Salt Lake Potash Limited (Salt Lake Potash or the Company) is pleased to announce it has signed a Native Title Land Access and Brine Minerals Exploration Agreement (the Agreementwith Tarlka Matuwa Piarku (Aboriginal Corporation) RNTBC (TMPAC) covering the Lake Way Project area.

TMPAC have entered into the Agreement with Salt Lake Potash on behalf of the Wiluna People who are the recognised Native Title Holders of the land covering the Lake Way Project area. TMPAC have also provided consent for the total area required for the construction and operation of the Williamson Ponds.

The signing of the Agreement with TMPAC and receipt of TMPAC’s consent for the Williamson Ponds is a major milestone in the development of the Lake Way Project and positions Salt Lake Potash to accelerate the works program for the Williamson Ponds.

Salt Lake Potash’s Chief Executive Officer, Mr Tony Swiericzuk, said:

“It has been a pleasure working with TMPAC to develop an agreement which respects the significance of the area’s heritage and also enables us to progress the Lake Way Project. The signing of the Agreement is a key milestone for construction activities to commence and the Company’s goal of developing the first SOP project within Australia. We look forward to building on the strong working relationship with TMPAC as we progress our plans to develop the Lake Way Project.”

Having signed the Agreement, Salt Lake Potash is looking to accelerate works at Lake Way, including:

1.   Construction of Williamson Ponds – Key contracts in respect of the construction of the Williamson Ponds are in the process of being finalised and construction equipment will be mobilising shortly in preparation for the imminent planned works to begin on the Williamson Ponds at Lake Way. The completion of this work program will result in the construction of Australia’s first commercial scale SOP evaporation ponds.

2.   Resource Definition Program – A maiden Mineral Resource Estimate for Lake Way (Blackham tenements only) was reported in July 2018. Work is currently underway to enable the Company to report a Mineral Resource Estimate for the lake bed brine and the paleochannel aquifer for the ‘whole of lake’, which will enable the Company to examine larger production options.

Salt Lake Potash (SO4) – September 2018 Quarterly Report and Appendix 5B

The Board of Salt Lake Potash Limited (the Company or SLP) is pleased to present its Quarterly Report for the period ending 30 September 2018.

The Company’s primary focus is progressing the development of the Goldfields Salt Lakes Project (GSLP), intended to be the first salt-lake brine Sulphate of Potash (SOP) production operation in Australia.

Highlights for the quarter and subsequently include:

APPOINTMENT OF MANAGING DIRECTOR / CEO

  • Highly regarded mining executive Tony Swiericzuk appointed as Managing Director and Chief Executive Officer of Salt Lake Potash effective 5 November 2018.
  • Mr Swiericzuk recently spent 9 years with Fortescue Metals Group, including as Director Business Development and Exploration, General Manager Christmas Creek Mine and General Manager Port.
  • Mr Swiericzuk’s initial focus will be the rapid development of Australia’s first SOP operation.

LAKE WAY

Maiden Resource for Lake Way

  • Measured mineral resource estimate of 32,000t SOP for the Williamson Pit Brine. The resource grade of 25kg/m3of SOP is easily the highest grade SOP brine resource in Australia.
  • Indicated resource estimate of 1,900,000t SOP calculated from Total Porosity (Stored) and 490,000t calculated from Drainable Porosity reported for the Blackham Resources tenements.

Scoping Study for Low Capex, High Margin Demonstration Plant

  • The Company completed a Scoping Study on the development of a 50,000tpa SOP Demonstration Plant at Lake Way that supports a low capex, highly profitable, staged development model, with total capital costs of approximately A$49m and average cash operating costs (FOB) of approximately A$387/t.
  • The Demonstration Plant is intended to validate the technical and commercial viability of brine SOP production from the GSLP, providing the basis to build a world class, low cost, long life SOP operation across the 9 lakes in the GSLP.

Process Testwork

  • Completed validation testwork that confirmed the process flowsheet to be used in the Lake Way Demonstration Plant Scoping Study.
  • A bulk field evaporation trial processing both Lake Way and Williamson Pit brine is ongoing, to confirm the modelled evaporation parameters and produce harvest salt samples for SOP production.

Geotechnical Investigations

  • The Company significantly progressed the design of the Williamson Ponds to dewater the Williamson Pit at Lake Way.

Approval to Construct Williamson Ponds

  • The Department of Mines, Industry Regulation and Safety (DMIRS) gave environmental approval for the pond system to dewater the Williamson Pit at Lake Way.

LAKE WELLS

MOU with Australian Potash to study sharing infrastructure and other costs at Lake Wells

  • The Company and Australian Potash Limited (ASX: APC) entered into a Memorandum of Understanding and Co-operation Agreement to undertake a joint study of the potential benefits of development cost sharing for each Company’s projects at Lake Wells.

Granting of Mining Lease

  • The Company’s first Mining Lease at Lake Wells covering 87.4 km2 was granted, a significant milestone in the Project’s development pathway.

LAKE BALLARD

  • A fieldwork programme of 38 test pits was completed over the extent of the lake area.  The test pits enabled geology, brine chemistry and hydraulic parameters to be understood. 
  • Commenced site evaporation trials to confirm pathway for salt production in field conditions.

SOP SAMPLE PRODUCTION

  • SOP granulation testwork produced initial samples for marketing and product quality assessment.
  • Testwork began in SLP’s in-house laboratory to replicate process flowsheet on larger batch scale. 

 

APPOINTMENT OF MANAGING DIRECTOR / CEO

Subsequent to the end of the quarter, the Company appointed Tony Swiericzuk as Managing Director and Chief Executive Officer (CEO), effective 5 November 2018.

Mr Swiericzuk is a Mining Engineer with outstanding credentials as a builder and operator of mining projects, having recently been General Manager of the Christmas Creek Mine from 2012 to 2017. He oversaw the construction, commissioning and ramp-up of this project from 15Mtpa to 60Mtpa in his initial 2 year period, then proceeded to optimise the operation and help drive FMG to become the world’s lowest cost iron ore producer.

In his initial years at FMG Mr Swiericzuk was General Manager Port Operations in Port Hedland and managed the ramp up from 20Mtpa to 60Mtpa from 2009 to 2011.

Mr Swiericzuk has the ideal operating and commercial experience to rapidly deliver on the exceptional potential of the Goldfields Salt Lakes Project (GSLP). The GSLP is a technically advanced, sustainable and highly scalable project to produce sought-after chlorine free fertilisers for the export and domestic markets.

Mr Swiericzuk’s diverse background in large scale logistics operations will be a substantial benefit to the development of the GSLP and he also intends to utilise the tried and proven methods which were essential in making FMG the lowest cost iron ore producer in the world.

Current CEO of the Company, Mr Matthew Syme, was integral to Mr Swiericzuk’s appointment and will remain a director and consultant to the Company, ensuring a seamless handover.

THE GOLDFIELDS SALT LAKES PROJECT

The Company’s long term plan is to develop an integrated SOP operation, producing from a number (or all) of the lakes within the GSLP, after confirming the technical and commercial elements of the Project through construction and operation of a Demonstration Plant producing up to 50,000tpa of SOP.

The GSLP has a number of important, favourable characteristics:

  • Very large paleochannel hosted brine aquifers at each Lake, with chemistry amenable to production of salts by solar evaporation for SOP production, extractable from both low cost trenches and deeper bores;
  • Over 3,300km2 of playa surface, with in-situ clays suitable for low cost on-lake pond construction;
  • Excellent evaporation conditions;
  • Excellent access to transport, energy and other infrastructure in the major Goldfields mining district;
  • Lowest quartile capex and opex potential based on the Lake Wells Scoping Study;
  • Clear opportunity to reduce transport costs by developing lakes closer to infrastructure and by capturing economies of scale;
  • Multi-lake production offers operational flexibility and diversification of risk from localised weather events;
  • The very high level of technical validation already undertaken at Lake Wells substantially applies to the other lakes in the GSLP; and
  • Potential co-product revenues, particularly where transport costs are lowest

Salt Lake Potash will progressively explore the lakes in the GSLP with a view to estimating resources for each Lake, in parallel with the development of the Demonstration Plant. Exploration of the lakes will be prioritised based on likely transport costs, scale, permitting pathway and brine chemistry.

The Company’s Memorandum of Understanding with Blackham Resources Limited (see ASX Announcement dated 12 March 2018) offers the potential for an expedited path to development at Lake Way, possibly the best site for a 50,000tpa Demonstration Plant in Australia.

A Scoping Study on the development of a 50,000tpa SOP Demonstration Plant at Lake Way was completed during the quarter, supporting a low capex, highly profitable, staged development model, with total capital costs of approximately A$49m and average cash operating costs (FOB) of approximately A$387/t.

LAKE WAY

Lake Way is located in the Goldfields region of Western Australia, less than 15km south of Wiluna. The surface area of the Lake is over 270km2.

Salt Lake Potash holds two Exploration Licences (one granted and one under application) covering most of Lake Way, including the paleochannel defined by previous exploration. The northern end of the Lake is largely covered by a number of Mining Leases, held by Blackham Resources Limited (Blackham), the owner of the Wiluna Gold Mine.

The Company entered into a Memorandum of Understanding with Blackham in March 2018 to investigate the development of an SOP operation on Blackham’s existing Mining Leases at Lake Way, including, initially, a 50,000tpa Demonstration Plant.

The Wiluna region is an historic mining precinct dating back to the late 19th century. It has been a prolific nickel and gold mining region with well developed, high quality infrastructure in place.

The Goldfields Highway is a high quality sealed road permitted to carry quad road trains and passes 2km from the Lake. The Goldfields Gas Pipeline is adjacent to SLP’s tenements, running past the eastern side of the Lake.

Lake Way has some compelling advantages which potentially make it an ideal site for an SOP operation, including:

  • Likely substantial capital and operating savings from sharing overheads and infrastructure with the Wiluna Gold Mine, including the accommodation camp, flights, power, maintenance, infrastructure and other costs.
  • The site has excellent potential freight solutions, being adjacent to the Goldfields Highway, which is permitted for heavy haulage, quad trailer road trains to the railhead at Leonora, or via other heavy haulage roads to Geraldton Port.
  • A Demonstration Plant would likely be built on Blackham’s existing Mining Leases.
  • SLP would dewater the existing Williamson Pit on Lake Way, prior to Blackham mining. The pit contains an estimated 1.2GL of brine at the exceptional grade of 25kg/m3 of SOP. This brine is potentially the ideal starter feed for evaporation ponds, having already evaporated from the normal Lake Way brine grade, which averages over 14kg/m3.
  • The high grade brines at Lake Way will result in lower capital and operating costs due to lower extraction and evaporation requirements.
  • There would be substantial savings to both parties from co-operating on exploration activities on each other’s ground.
  • The presence of clays in the upper levels of the lake which should be amenable to low cost, on-lake evaporation pond construction.

Mineral Resource

A maiden Mineral Resource Estimate for Lake Way (Blackham tenements only) was estimated by Groundwater Science Pty Ltd, an independent hydrogeological consultant with substantial salt lake brine expertise.

Areas outside the Blackham tenements at Lake Way, including the remaining playa surface covered by SLP tenements and applications, were not considered as part of the Mineral Resource estimate and provide significant future upside to increase resources at Lake Way.

Scoping Study

In July 2018, the Company completed a Scoping Study on development of a 50,000tpa sulphate of potash (SOP) Demonstration Plant at Lake Way that supports a low capex, highly profitable, staged development model.

The Demonstration Plant is supported by the Indicated resource estimate of 1,900,000t SOP calculated from Total Porosity (Stored) and 490,000t calculated from Drainable Porosity, a multiple of the resource required to support a 50,000tpa Demonstration Plant for 2-3 years.

The Demonstration Plant will produce up to 50,000tpa of high quality, standard SOP from hypersaline brine extracted from Lake Way via a system of shallow trenches.

The extracted brine will be transported to a series of solar evaporation ponds built on the Lake where selective evapo-concentration will precipitate potassium double salts in the final evaporation stage. These potassium-rich salts will be mechanically harvested and processed into SOP in a purification and crystallisation plant. The final product will then be transported for sale to domestic and international markets.

The Company has previously tested and verified, at Lake Wells, all the major technical foundations for production of SOP from salt lake brine under actual site conditions and across all seasons. These technical achievements are broadly applicable across all the lakes in the GSLP and form part of the inputs into the Scoping Study.  Subsequent testing of salts generated from Lake Way brine at the Saskatchewan Research Council (“SRC”) (Canada) has confirmed the validity of the GSLP process flowsheet selected for the Lake Way Demonstration Plant.

The Scoping Study established the indicative costs of the Demonstration Plant to +/- 30% accuracy for Operating Costs and -10%/+30% for Capital Expenditure.

Ongoing Hydrogeological Testwork

Following the completion of the Scoping Study, pumping of four trenches continued (LYTR01, 02, 03 and 04).  Trenches 1 and 2 were pumped for approximately 90 days each and terminated in mid-September in order to observe recovery.  Pumping of trenches 3 and 4 continues, to observe recharge effects during the upcoming wet season.

The extended time of pumping enabled the reconfirmation of the specific yield parameters quoted in the Scoping Study.  The analysis of the final dataset from Trenches 1 and 2 is expected to provide good estimations of aquifer transmissivity and Drainable Porosity that will be key to the further development of the numerical groundwater model.

Throughout the trench testing a brine sample was taken from each trench on a weekly basis with the objective of identifying any variation in brine grade due to the pumping. The results obtained to date show minimal variation in brine grade as the pumping progressed.

Geotechnical Investigations

During the quarter, the Company significantly progressed design of the Williamson Ponds to dewater the Williamson Pit at Lake Way.

A Cone Penetration Test (CPT) rig completed a soil testing programme across the Williamson Pond footprint. Thirty-one CPT’s were undertaken to measure the strength and permeability characteristics of lakebed sediments. The CPT’s provided data to define the geotechnical parameters that are required for final pond analysis and design.

Detailed engineering of the Williamson Ponds commenced, with geotechnical design work completed including CPT data analysis, trafficability assessment, access road analysis, setup of seepage models, borrow pit assessments and development of the Pond construction methodology. Further analysis and design work will produce design drawings for the Ponds.

Civil engineering work also included topographical surveys of the pond and process plant site areas.

Given the unique design and site conditions, the Company is planning an Earthworks Trial as part of the early works construction activities. The trial will finalise earthworks equipment selection and refine the construction methodology for on-lake embankments.

The Company is progressing with the contractor selection process for dewatering of the Williamson Pit.

Mines Department Approval

SLP received environmental approval from the Department of Mines, Industry Regulation and Safety (DMIRS) for the pond system to dewater the Williamson Pit at Lake Way.

DMIRS has given environmental approval to construct ponds totalling up to 133Ha, as well as ancillary infrastructure and a trench to provide conditioning brine to manage the chemistry of the brine extracted from the Williamson Pit.

The Williamson Ponds will be the first operational scale SOP evaporation ponds built on a salt lake in Australia – an important part of the staged de-risking and development at Lake Way and across the Goldfields Salt Lakes Project.

Construction of the Williamson ponds will proceed upon:

·     completion of final engineering designs and contractor engagements;

·     completion of formal documents with Blackham to supersede the MOU (already substantially advanced); and

·     satisfaction of aboriginal heritage requirements. 

Process Testwork

Brine evaporation modelling, conducted by international solar pond experts, Ad Infinitum, indicated the salts produced at Lake Way through the natural evaporation process will be comparable to those produced at Lake Wells and therefore suitable for conversion into SOP. 

The Company executed a range of process development testwork to confirm the Ad Infinitum model and validate inputs to the Lake Way Scoping Study production model. The testwork uses both brines from the lake playa and the super-concentrated brines from the Williamson Pit.

The Lake Way Site Evaporation Trial (SET) continued to process significant volumes of both Lake and Williamson Pit brine. Assay results from samples collected at regular intervals are used to confirm the evaporation pathway aligns closely with predictions from the Company’s evaporation modelling.

Harvest salt from the laboratory evaporation of Lake Way brine was processed at SRC (Canada) to confirm the flowsheet for the Lake Way Demonstration Plant. The Lake Way flowsheet utilises the same unit operations as the previously piloted Lake Wells flowsheet, giving the company confidence that the process is robust and highly transferrable with only minor modifications to crush size.

LAKE WELLS

MOU with Australia Potash

In September 2018, Salt Lake entered into a Memorandum of Understanding and Co-operation Agreement with Australian Potash Limited (ASX: APC) to undertake a joint study of the potential benefits of development cost sharing for each Company’s project developments at Lake Wells.

The Companies’ substantial project holdings at Lake Wells are contiguous with many common infrastructure elements, including access roads, proximity to the Leonora rail terminals, and potential power and fresh water solutions. Both Companies anticipate substantial potential Capex and Opex benefits from some level of infrastructure sharing, with further potential benefits arising from shared or common evaporation and salt processing facilities.

The Companies have agreed to constitute a joint study team to carry out an initial assessment of the merits of infrastructure cooperation. The team will also conduct a high-level review of potential benefits of upstream operational synergies. A substantial part of the Study work will be outsourced to independent engineers and both Companies intend to continue with their independent project developments in parallel with the Study.

Mining Lease

The Company’s first Mining Lease at Lake Wells was granted in September 2018, a significant milestone in the Projects development pathway.

ML 38/1278 covers 87.4km2 in the south east corner of the Lake Wells project. The Mining Lease has an initial 21 year term.

LAKE BALLARD

Geological Interpretation

Lake Ballard project is located about 15 km north of Menzies. The playa is a significant regional landform with a surface area of over 626km2. The geology of Lake Ballard is similar to that encountered at other lakes in the Company’s GSLP.   

The Lake Ballard drainage is incised into the granite-greenstone basement and now in filled with a mixed sedimentary sequence. The lake bed sediments are underlain by a deeper paleochannel characterised by a sandy layer at its base.

The lake bed sediments comprise a mixed sequence of sands, clays and silts reflecting the climatic and depositional environment that created firstly the paleochannel and subsequently the lake.

At Lake Ballard the surficial deposits also include a highly consolidated sand layer between 1.5 and 3m depth.  This layer is non continuous across the lake and acts as a local aquiclude that results in a release of hydrostatic pressure and localised high flows when broken through.

Surface Aquifer Exploration Programme

The Company mobilised an amphibious excavator on Lake Ballard in July 2018 to complete a surface aquifer exploration programme.

The objective of the programme was to gather geological and hydrological data about the shallow brine aquifer hosted by the Quaternary alluvium stratigraphic sequence in the upper levels of the Lake. The programme is to evaluate the geology of the shallow lakebed sediments, and to undertake pumping trials to provide estimates of the potential brine yield from trenches in the shallow sediment and ultimately enable estimation of an indicated resource calculated from Total Porosity and Drainable Porosity. The excavator programme provides important geological and geotechnical information for potential construction of trenches and on-lake brine evaporation ponds.

Previous work in 2017 included the excavation of 163 test pits and 8 trenches and brine sampling. Work during the quarter included re-evaluation of gravity data to locate the deepest part of the paleochannel (the Thalweg), resampling and hydraulic testing of 38 test pits across the lake comprising 17 of the 2017 test pits at the eastern end of the lake and 21 new test pits located across the lake.  The new pits were logged geologically and all pits were sampled for brine chemistry and hydraulic testing.  In addition, 170 test pits from the 2017 and 2018 programmes were rehabilitated and one of the 2017 trenches extended to a total length of 180m.

The programme is ongoing and involves an auger drilling programme and trench testing.

Gravity Re-evaluation

The gravity data initially collected in 2017 was re-evaluated to identify the location of the Thalweg. Of particular interest was the eastern end where the channel crosses from Lake Ballard to the adjacent Lake Marmion. This assessment will facilitate the location of targets for future drilling.

Test Pits

38 test pits were assessed in 2018 to develop a greater understanding of the geology and brine chemistry across the lake. The pits were dug to 5m. In-situ samples were taken using Shelby tubes for 5 pits to assess total and drainable porosity of the sediment. Preliminary results of the data available are summarised in Table 5.

Brine Chemistry

Over 140 brine samples have been analysed for Lake Ballard. Brine chemistry is reasonably uniform across the lake. 

All brine samples are considered to be composite samples representing the whole excavated or drilled depth at each location. Given the proposed abstraction techniques will involve trenches excavated to at least 4m across a large portion of the playa, the use of composite samples is representative of the brine that will be extracted.

Between 2017 and 2018, 142 brine samples were analysed from the test pits and trenches. The full suite of brine samples including their location is attached in Appendix 2. 

The spatial distribution of potassium concentration across the samples is reasonably consistent ranging from 1,040 to 2,460 mg/L. There are several low measurements of potassium, all of which relate to samples taken from test pits very close to the lake shore. At the lake shore there is the potential for local dilution following freshwater runoff onto the lake that may result in a localised area of lower brine concentration.

Auger Drilling

The Company commenced an auger drilling programme at Lake Ballard in September to obtain insitu samples for geological logging, porosity measurement, specific yield testing and brine sampling. The holes were drilled using a track mounted auger rig, capable of drilling to between 15 – 20m depth depending on ground conditions.

The programme consisted of a total of 15 holes at 11 locations. Location and total depth is outlined in Table 6. A brine sample was also recovered at each location. 

The core sample was collected using hollow stem augers within which a 1m plastic tube was inserted.  The plastic tubes were sealed immediately upon retrieval to prevent drying and loss of entrained brine.

The programme was successful with over 130m of core collected, from which 45 samples were selected for laboratory analysis of total and drainable porosity.  The core samples chosen for analysis were representative of the programme in terms of both location and depth interval from surface to total depth.

All core was delivered to Core Laboratories and the analysis will be completed and reported in the next quarter.

Further Planned Work

The Company intends to undertake further work at Lake Ballard, including pumping of 2 test trenches to determine aquifer properties including hydraulic conductivity and Drainable Porosity.

EVAPORATION MODELLING

The Company continued to develop in-house capability to model evaporation pathways for lake brines under differing conditions to inform evaporation pond design and model salt production. An in-house modelling tool has been developed using a combination of standard engineering expressions and a well established and proven chemical-thermodynamic database.

SOP SAMPLE PRODUCTION

Perth Laboratory

The Company began the process of converting 10 tonnes of harvest salts collected from the Lake Wells SET into SOP samples at the Company’s in-house laboratory in Perth at the end of the quarter.  The process being used is based upon the flowsheet previously tested by SRC.

An initial 2 tonnes of salt were selected to represent a range of seasonal outputs from the SET. The process will initially be simulated through a series of batch operations to investigate the effects of seasonality on process performance.

The ultimate aim of the in-house work is to generate several hundred kilograms of lake-derived SOP product for assessment of quality and for marketing purposes. The operation also provides the Company’s process team valuable hands-on experience in the operation of a salt-brine process.    

Product Preparation

The Company is considering a range of product preparations for commercial scale production of SOP including standard (powder), compacted, spherical (granular) and soluble products.

During the quarter the Company engaged FEECO, USA to conduct granulation testwork using growth agglomeration techniques to generate a spherical fertilizer granule from Lake Wells produced SOP. The tests found that an attractive, 2mm to 4mm spherical SOP granule can be readily produced with the desired strength and physical properties.

APPENDIX 3 – JORC TABLE ONE

Section 1: Sampling Techniques and Data

CriteriaCriteria

JORC Code explanationJORC Code explanation

CommentaryCommentary

Sampling techniques

Nature and quality of sampling (eg cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc). These examples should not be taken as limiting the broad meaning of sampling.

Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used.

Aspects of the determination of mineralisation that are Material to the Public Report.

In cases where ‘industry standard’ work has been done this would be relatively simple (eg ‘reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay’). In other cases more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (eg submarine nodules) may warrant disclosure of detailed information.

Sampling involved the excavation of 38 test pits over the tenement area to a depth of 4mbgl or weathered basement whichever was encountered first. 

A brine sample and duplicate were taken from each test pit and trench for analysis.

Samples were taken manually by initially rinsing out the bottle with brine from the pit or trench and then placing the bottle in the test pit or trench and allowing it to fill.

Samples were analysed for K, Mg, Ca, Na, Cl, SO4, HCO3, NO3, pH, TDS and specific gravity.

Each test pit was geologically logged and a sample taken each 1m depth.

Drilling techniques

Drill type (eg core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (eg core diameter, triple or standard tube, depth of diamond tails, face-sampling bit or other type, whether core is oriented and if so, by what method, etc).

No drilling results are reported.  Test pits were dug with an excavator approximately 2m long x 1m wide x 4m deep.

 

Drill sample recovery

Method of recording and assessing core and chip sample recoveries and results assessed.

Measures taken to maximise sample recovery and ensure representative nature of the samples. Whether a relationship exists between sample recovery and grade and whether sample bias may have occurred due to preferential loss/gain of fine/coarse material.

Samples from the test pits were logged each bucket and a representative sample bagged.

100% of excavated sample was available for sampling.  The ability to see the bulk sample facilitated the selection of a representative sample.

There is no relationship between sample recovery and grade and no loss of material as a result of excavation.

Logging

Whether core and chip samples have been geologically and geotechnically logged to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies.

Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc) photography.

The total length and percentage of the relevant intersections logged.

The geological logging is sufficient for the purposes of identifying variations in sand/ clay and silt fraction within the top 4m.  For a brine abstraction project, the key parameters are the hydraulic conductivity and storativity of the host rock, which will be determined during test pumping of trenches.

The logging is qualitative.

The entire pit depth was logged in every case.

Sub-sampling techniques and sample preparation

If core, whether cut or sawn and whether quarter, half or all core taken.

If non-core, whether riffled, tube sampled, rotary split, etc and whether sampled wet or dry.

For all sample types, the nature, quality and appropriateness of the sample preparation technique.

Quality control procedures adopted for all sub-sampling stages to maximise representivity of samples.

Measures taken to ensure that the sampling is representative of the in situ material collected, including for instance results for field duplicate/second-half sampling.

Whether sample sizes are appropriate to the grain size of the material being sampled.

No drilling results are reported.

At all test pits brine samples were taken from the pit after 24hours or once the pit had filled with brine.  The brine samples taken from the pits are bulk samples which is an appropriate approach given the long-term abstraction technique of using many kilometres of trenches to abstract brine from the upper 4m.

All the samples taken were incorporated into a rigorous QA / QC programme in which Standards and Duplicates were taken. The samples were taken in sterile plastic bottles of 250ml capacity.

Excavated lake bed samples were sealed in plastic bags.  For all brine samples (original or check samples) the samples were labelled with the alphanumeric code Y8001, Y80002.

Lake bed samples were labelled with the test pit locator LYTT01, LYTT02 etc. and the depth from which they were taken.

Quality of assay data and laboratory tests

The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total.

For geophysical tools, spectrometers, handheld XRF instruments, etc, the parameters used in determining the analysis including instrument make and model, reading times, calibrations factors applied and their derivation, etc.

Nature of quality control procedures adopted (eg standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (ie lack of bias) and precision have been established.

The brine samples were sent to Bureau Veritas Laboratories in Perth, WA with the duplicates being held by SLP.  Every 10th duplicate was sent to Intertek, an alternate laboratory for comparison purposes.

No laboratory analysis was undertaken with geophysical tools.

Soil samples and laboratory derived hydraulic conductivity, total porosity and drainable porosity samples were analysed by Core Laboratories in Perth WA.  All laboratories used are NATA certified.

Verification of sampling and assaying

The verification of significant intersections by either independent or alternative company personnel.

The use of twinned holes.

Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols.

Discuss any adjustment to assay data.

No drilling results reported.

All sampling and assaying is well documented and contained on SLP’s internal database.

No adjustments have been made to assay data

Location of data points

Accuracy and quality of surveys used to locate drill holes (collar and down-hole surveys), trenches, mine workings and other locations used in Mineral Resource estimation.

Specification of the grid system used.

Quality and adequacy of topographic control.

All coordinates were collected by handheld GPS.

The grid system is the Australian National Grid Zone MGA 51 (GDA 94).

The is no specific topographic control as the lake surface can essentially be considered flat.

Data spacing and distribution

Data spacing for reporting of Exploration Results.

Whether the data spacing and distribution is sufficient to establish the degree of geological and grade continuity appropriate for the Mineral Resource and Ore Reserve estimation procedure(s) and classifications applied.

Whether sample compositing has been applied.

The Lake Ballard area was calculated by digitising the lake surface and removing the area covered by the islands the approximate area is 626km2.  38 test pits were excavated over the lake surface resulting in 1 excavation per 16.47Km2. Which whilst it is a low density of investigation for a salt-lake it is sufficient to establish variations in brine content.

Sample compositing has not been applied.

Orientation of data in relation to geological structure

Whether the orientation of sampling achieves unbiased sampling of possible structures and the extent to which this is known, considering the deposit type.

If the relationship between the drilling orientation and the orientation of key mineralised structures is considered to have introduced a sampling bias, this should be assessed and reported if material.

There are no structural or geological controls with respect to sampling the lake bed sediments. 

Geological influence on the brine is limited to the aquifer parameters of the host rock, namely the hydraulic conductivity, drainable porosity and storativity.

Sample security

The measures taken to ensure sample security.

SLP field geologists were responsible for collecting, sealing and labelling brine and Shelby tube samples prior to shipping to the Perth labs and the SLP offices.  The security measures for the material and type of sampling at hand was appropriate.

Audits or reviews

The results of any audits or reviews of sampling techniques and data.

No audits or review of sampling techniques have been undertaken.  The brine chemistry data has been reviewed for charge balance.

 

Section 2: Reporting of Exploration Results

CriteriaCriteria

JORC Code explanationJORC Code explanation

Commentary

Mineral tenement and land tenure status

Type, reference name/number, location and ownership including agreements or material issues with third parties such as joint ventures, partnerships, overriding royalties, native title interests, historical sites, wilderness or national park and environmental settings.

The security of the tenure held at the time of reporting along with any known impediments to obtaining a licence to operate in the area.

The Lake Ballard project area is covered by Exploration licences E29/0912, E29/1011, E29/1022, E29/0958, E29/1021, E29/0948, E29/1020 and E29/0913.

All tenements are held by Piper Preston Pty Ltd, a wholly owned subsidiary of Salt Lake Potash Limited.

Exploration done by other parties

Acknowledgment and appraisal of exploration by other parties.

No previous work has been carried out on Lake Ballard for potash exploration.

Geology

Deposit type, geological setting and style of mineralisation.

The deposit is a salt-lake brine deposit.

The lake setting is typical of a Western Australian palaeovalley environment. Ancient hydrological systems have incised palaeovalleys into Archaean basement rocks, which were then infilled by Tertiary-aged sediments typically comprising a coarse-grained fluvial basal sand overlaid by palaeovalley clay with some coarser grained interbeds. The clay is overlaid by recent Cainozoic material including lacustrine sediment, calcrete, evaporite and aeolian deposits. 

Drill hole Information

A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drill holes:

o   easting and northing of the drill hole collar

o   elevation or RL (Reduced Level – elevation above sea level in metres) of the drill hole collar

o   dip and azimuth of the hole

o   down hole length and interception depth

o   hole length.

If the exclusion of this information is justified on the basis that the information is not Material and this exclusion does not detract from the understanding of the report, the Competent Person should clearly explain why this is the case.

No drill results are reported. 

38 test pits and 8 trenches were excavated on the lake surface.

All test pit locations are presented in the report.

Data aggregation methods

In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (eg cutting of high grades) and cut-off grades are usually Material and should be stated.

Where aggregate intercepts incorporate short lengths of high grade results and longer lengths of low grade results, the procedure used for such aggregation should be stated and some typical examples of such aggregations should be shown in detail.

The assumptions used for any reporting of metal equivalent values should be clearly stated.

Within the salt-lake extent no low-grade cut-off or high-grade capping has been implemented due to the consistent nature of the brine assay data.

Relationship between mineralisation widths and intercept lengths

These relationships are particularly important in the reporting of Exploration Results.

If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported.

If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (eg ‘down hole length, true width not known’).

The chemical analysis from each of the test pits has shown the that the brine resource is consistent and continuous through the full thickness of the Lake Playa sediments unit. The unit is flat lying all test pits were excavated into the lake sediments to a depth of 4m or basement, the intersected depth is equivalent to the vertical depth and the thickness of mineralisation.

 

Diagrams

Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any significant discovery being reported These should include, but not be limited to a plan view of drill hole collar locations and appropriate sectional views.

All location maps and sections are contained within the body of the report.

Balanced reporting

Where comprehensive reporting of all Exploration Results is not practicable, representative reporting of both low and high grades and/or widths should be practiced to avoid misleading reporting of Exploration Results.

A summary of the average of all brine results has been included in the body of the report.

The total and drainable porosity results for 4 test pits where Shelby tube insitu samples were taken are included in the body of the report.

Other substantive exploration data

Other exploration data, if meaningful and material, should be reported including (but not limited to): geological observations; geophysical survey results; geochemical survey results; bulk samples – size and method of treatment; metallurgical test results; bulk density, groundwater, geotechnical and rock characteristics; potential deleterious or contaminating substances.

All material exploration data available at the time of writing has been reported.

Further work

The nature and scale of planned further work (eg tests for lateral extensions or depth extensions or large-scale step-out drilling).

Diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, provided this information is not commercially sensitive.

Trench tests will commence and be concluded in Q2, an auger drilling programme will be completed and the results reported in Q2.

Salt Lake Potash (SO4) Mines Department Approval to Construct Williamson Ponds at Lake Way

Salt Lake Potash (the Company or SLP) is pleased to announce that the Company has now received approval from the Department of Mines, Industry Regulation and Safety (DMIRS) for a pond system to dewater the Williamson Pit at Lake Way.

DMIRS has given approval to construct ponds totalling up to 133Ha, as well as ancillary infrastructure and a trench to provide conditioning brine to manage the chemistry of the brine extracted from the Williamson Pit.

The Williamson Pit at Lake Way has a JORC Measured Resource of 1.26Gl of brine at an average SOP grade of 25kg/m3, easily the highest grade SOP brine resource in Australia. Pursuant to the Company’s MOU with Blackham Resources Limited, the owner of the Williamson Pit, SLP will dewater the Pit ahead of Blackham re-entering the Pit for mining.

The Williamson Ponds will be the first operational scale SOP evaporation ponds built on a salt lake in Australia – an important part of the staged de-risking and development at Lake Way and across the Goldfields Salt Lakes Project.

Construction of the Williamson ponds will proceed upon:

  • completion of final engineering designs and contractor engagements;
  • completion of formal documents with Blackham to supersede the MOU (already substantially advanced); and
  • satisfaction of aboriginal heritage requirements. 

Salt Lake CEO, Matt Syme saidThis approval from DMIRS is an important milestone in our plans for staged development at Lake Way and across the Goldfields Salt Lakes Project more broadly. Our objective is to build the most sustainable and rewarding fertiliser project in the world and low cost, environmentally friendly on-lake ponds are an important part of our business model. Construction and filling of the Williamson Ponds will provide very strong validation of that model“.

OPERATING AND FINANCIAL REVIEW

Operations

The Company’s aim is to develop the first salt-lake brine Sulphate of Potash (SOP) operation in Australia, starting with a Demonstration Plant producing up to 50,000tpa of SOP, at the Goldfields Salt Lakes Project (GSLP) located in the Northern Goldfields of Western Australia. The Company’s multi-lake portfolio, and the comprehensive technical achievements to date, highlight the potential for a very economic, large scale and long term project.

Highlights

The Company has undertaken a significant level of work during the year across a range of disciplines and has achieved a number of very important milestones, substantially progressing the Company’s aim is to develop the first salt-lake SOP operation in Australia. Highlights during, and subsequent to the end of, the financial year include:

LAKE WAY

MOU with Blackham Resources to access Lake Way

·      The Company entered into a Memorandum of Understanding (MOU) with Blackham Resources Limited (Blackham) to investigate the potential development of a SOP operation based at Lake Way, near Wiluna.

Pursuant to the MOU with Blackham, the Company would construct an initial pond system to dewater Blackham’s Williamson Pit, which contains approximately 1.2GL of super-saturated brine, with a very high average SOP content of 25kg/m3. These Williamson Ponds would comprise approximately 1/3 of the total Demonstration Plant pond area, and dewatering of the Williamson Pit offers a shorter development time due to its very high grade and salt saturation.

Scoping Study for Low Capex, High Margin Demonstration Plant

·      The Company completed a Scoping Study on the development of a 50,000tpa SOP Demonstration Plant at Lake Way that supports a low capex, highly profitable, staged development model, with total capital costs of approximately A$49m and average cash operating costs (FOB) of approximately A$387/t.

The Demonstration Plant is intended to validate the technical and commercial viability of brine SOP production from the GSLP, providing the basis to build a world class, low cost, long life SOP operation across the 9 lakes in the GSLP.

LAKE WELLS

Process Testwork

·      The Company completed pilot scale crystalliser validation testwork at a leading crystalliser vendor in the United States, processing approximately 400 kg of crystalliser feed salt (schoenite concentrate), produced from previous Lake Wells development work at Saskatchewan Research Council (SRC). The testwork successfully produced high quality SOP crystals, representative of a full scale plant product.

·      The Site Evaporation Trial (SET) at Lake Wells was decommissioned after completing over 18 months of operation under site conditions and through all seasons. The SET processed approximately 412 tonnes of brine and produced over 10 tonnes of harvest salts.

MOU with Australian Potash to study sharing infrastructure and other costs at Lake Wells

·      Subsequent to year end, the Company and Australian Potash Limited (ASX: APC) entered into a Memorandum of Understanding and Co-operation Agreement to undertake a joint study of the potential benefits of development cost sharing for each Company’s projects at Lake Wells.

·      The Company’s first Mining Lease at Lake Wells was granted subsequent to year end, a significant milestone in the Projects development pathway.

LAKE BALLARD

·      An initial surface aquifer exploration program was completed at Lake Ballard, comprising a total of 160 shallow test pits and 10 test trenches. This work provides preliminary data for the geological and hydrological models for the surface aquifer of the Lake, as well as brine, geological and geotechnical samples. 

·      Subsequent to year end exploration drilling and excavation continued with a view to reporting an initial JORC mineral resource estimate for the shall aquifer.

LAKE IRWIN

·      A surface aquifer exploration program was completed at Lake Irwin, comprising 56 shallow test pits and 5 test trenches. This work provides preliminary data for the geological and hydrological models of the surface aquifer of the Lake, as well as brine, geological and geotechnical samples. 

REGIONAL LAKES

·      The Company undertook initial surface brine sampling of the near surface aquifer and reconnaissance of access and infrastructure at all remaining Lakes held under the GSLP.

GOLDFIELDS SALT LAKE PROJECT

First MOU for an Offtake Agreement with Mitsubishi

·      The Company executed its first MOU for an Offtake Agreement with Mitsubishi, for the sales and offtake rights for up to 50% of the SOP production, from a Demonstration Plant at the GSLP, for distribution into Asia and Oceania and potentially other markets.

World Class Scale Revealed with Initial Exploration Target Estimation

·      The Company released an initial estimate of Exploration Targets for eight of the nine lakes comprising the Company’s GSLP. The ninth lake, Lake Wells, already having a Mineral Resource reported in accordance with the JORC code.

The total “stored” Exploration Target for the GSLP is 290Mt – 458Mt of contained Sulphate of Potash (SOP) with an average SOP grade of 4.4 – 7.1kg/m3 (including Lake Wells’ Mineral Resource of 80-85Mt). On a “drainable” basis the total Exploration Target ranges from 26Mt – 153Mt of SOP. The total playa area of the lakes is approximately 3,312km2.

The potential quantity and grade of this Exploration Target is conceptual in nature. There has been insufficient exploration to estimate a Mineral Resource and it is uncertain if further exploration will result in the estimation of a Mineral Resource.

Background

The Company is the owner of the Goldfields Salt Lakes Project (GSLP), which comprises nine large salt lakes in the Northern Goldfields Region of Western Australia.

The GSLP has a number of important, favourable characteristics:

·      Very large paleochannel hosted brine aquifers, with chemistry amenable to evaporation of salts for SOP production, extractable from both low-cost trenches and deeper bores;

·      Over 3,300km2 of playa surface, with in-situ clays suitable for low cost on-lake pond construction;

·      The total “stored” Exploration Target for the GSLP is 290Mt – 458Mt of contained Sulphate of Potash (SOP) with an average SOP grade of 4.4 – 7.1kg/m3 (including Lake Wells’ Mineral Resource of 80-85Mt). On a “drainable” basis the total Exploration Target ranges from 26Mt – 153Mt of SOP. [The potential quantity and grade of this Exploration Target is conceptual in nature. There has been insufficient exploration to estimate a Mineral Resource and it is uncertain if further exploration will result in the estimation of a Mineral Resource].

·      Excellent evaporation conditions;

·      Excellent access to transport, energy and other infrastructure in the Goldfields mining district;

·      Lowest quartile capex and opex potential based on the Lake Wells Scoping Study;

·      Clear opportunity to reduce transport costs by developing lakes closer to infrastructure and by capturing economies of scale;

·      Multi-lake production offers operational flexibility, cost advantages and risk mitigation from localised weather events;

·      The very high level of technical validation already undertaken at Lake Wells substantially applies to the other lakes in the GSLP; and

·      Potential co-product revenues, particularly where transport costs are lowest.

The Company’s long term plan is to develop an integrated SOP operation of global scale, producing high quality organic SOP from a number (or all) of the lakes within the GSLP, after confirming the technical and commercial elements of the Project through construction and operation of a Demonstration Plant producing up to 50,000tpa of SOP.

Demonstration Plant

The Company believes the advantages of the Demonstration Plant approach are:

·      While substantial salt-lake brine production of SOP is undertaken in China, Chile and the USA, it is new in Australia and overseas production models need to be tested and adapted for Australian conditions.

·      Proof of concept for SOP production from salt-lake brines in Australia will substantially de-risk the full-scale project, with commensurate improvement in financing costs and alternatives. While the Demonstration Plant does not benefit from economies of scale, it will provide financiers and partners a very reliable cost basis for larger scale, longer term operations, while still being low capex and high margin in its own right.

·      Refinement of design and costing of engineering elements at Demonstration Plant scale should result in considerable time and cost savings at larger scale.

·      Market acceptance of a new product in conservative agricultural markets is best achieved progressively and in conjunction with existing, established partner(s). It is important to establish Salt Lake’s product(s) as premium, sustainable nutrients in the key long-term markets, and staged production increments are the best way to achieve this objective.

·        A Demonstration Plant offers an accelerated pathway to initial production, with limited infrastructure requirements and a faster, simpler approval process. The Demonstration Plant is intended to operate for 12-24 months to establish parameters for larger scale production, and then be integrated into a larger operation. The Company’s objective is to commence construction in 2018, harvesting first salts in 2019, and producing first SOP in 2020.

Lake Way

Salt Lake holds two Exploration Licences (one granted and one under application) covering most of Lake Way, including the paleochannel defined by previous exploration. The Northern end of the Lake is largely covered by a number of Mining Leases, held by Blackham Resources Limited (Blackham), the owner of the Wiluna Gold Mine.

The Company entered into a Memorandum of Understanding with Blackham in March 2018 to investigate the development of an SOP operation on Blackham’s existing Mining Leases at Lake Way, including initially a 50,000tpa Demonstration Plant.

Lake Way is located less than 15km south of Wiluna. The Wiluna region is an historic mining precinct dating back to the late 19th century. It has been a prolific nickel and gold mining region with well developed, high quality infrastructure in place.

The Goldfields Highway is a high quality sealed road permitted to carry quad road trains and passes 2km from the Lake. The Goldfields Gas Pipeline is adjacent to SLP’s tenements, running past the eastern side of the Lake.

Scoping Study

In July 2018, the Company completed a Scoping Study on development of a 50,000tpa sulphate of potash (SOP) Demonstration Plant at Lake Way that supports a low capex, highly profitable, staged development model.

The Demonstration Plant is supported by an Indicated and Measured Mineral Resource (drainable) within the Blackham mining lease area totalling 500,000t (Stored Resource – 2Mt), a multiple of the resource required to support a 50,000tpa Demonstration Plant for 2-3 years.

Development Process

The Demonstration Plant is intended to validate the technical and commercial viability of brine SOP production from the GSLP, providing the basis to build a world class, low cost, long life SOP operation across the 9 lakes in the GSLP.

The Company has previously established that larger production volumes (400,000tpa) can result in operating costs in the lowest cost quartile for SOP production globally*. This is principally a result of the economies of scale inherent in the GSLP’s advantageous location in the Northern Goldfields mining district, mostly in the main cost centres of transport, labour and power.

Pursuant to the MOU with Blackham, the Company will construct an initial pond system to dewater the Williamson Pit, which contains approximately 1.2GL of super-saturated brine, with a very high average SOP content of 25kg/m3. These Williamson Ponds will comprise approximately 1/3 of the total Demonstration Plant pond area, and dewatering of the Williamson Pit offers a shorter development time due to its very high grade and saturation.

Process Testwork

The Company undertook a range of process development testwork to enhance the process model for both Lake Way and Lake Wells.

A large scale, continuous Site Evaporation Trial (SET) at Lake Wells was successfully completed over 18 months of operation under site conditions and through all seasons. The results of the SET are an Australian first and have provided significant knowledge to the Company on the salt crystallisation pathway under site conditions in Australia. 

The SET processed approximately 412 tonnes of Lake Wells brine and produced 10.3 tonnes of harvest salts. Site-produced harvest salts have been used in a range of subsequent process development testwork programs.

The Company has used the harvest salts produced by the SET to perform comprehensive process development testwork at Saskatchewan Research Council (SRC). Most recently, SRC completed locked cycle testwork that validated the SysCAD process flowsheet and demonstrated that the process converges quickly to operate at steady state.

In addition to locked cycle testing, 1,000kg of harvest salts from Lake Wells SET were processed by SRC to produce approximately 350kg of the flotation concentrate (crystalliser feed salt) which was then provided to a globally recognized crystalliser vendor for crystalliser testwork and equipment design. The tests generated samples with large chrystal size, similar to full scale production, and allowed the vendor to refine the design and pricing of a key process equipment item.

Building on the knowledge gained from the Lake Wells project, a staged engineering approach was used in the process development for Lake Way, whereby initial evaporation modelling was undertaken followed by laboratory tests and then field trials.  The initial brine evaporation modelling, conducted by international solar pond experts, Ad Infinitum, indicated that the predicted harvest salts produced at Lake Way are comparable to those produced at Lake Wells (containing a mix of Halite, Kainite and Schoenite) and therefore suitable for conversion into SOP. 

Laboratory evaporation tests were conducted by international laboratory and testing company, Bureau Veritas (BV), to validate the evaporation model.  BV completed a series of laboratory-scale brine evaporation trials at their Perth facility, under simulated average Lake Way climate conditions. This testwork confirmed the modelled brine evaporation pathways. Furthermore it demonstrated that the Williamson pit brine follows a similar evaporation pathway to Lake Way lake brine with similar brine chemistry and salts produced. This indicates that the Williamson Pit brine is a pre-concentrated version of the Lake Way brine, which provides the advantage of a large volume of brine that is essentially accelerated in the evaporation pathway.

A range of process development testwork to provide and validate inputs to the Lake Way Scoping Study production model was also undertaken, including field evaporation tests and metallurgical processing testwork on harvest salts. The testwork incorporates brines from the Lake itself, as well as the super-concentrated brines from the Williamson Pit.

The results of testwork undertaken to date support the Company’s aim to produce an organic premium SOP product from the GSLP. Salt Lake continues to progress testwork to refine products in line with offtake partner expectations.

MOU for Offtake with Mitsubishi

The Company executed a MOU for an Offtake Agreement with Mitsubishi for the sales and offtake rights for up to 50% of the SOP production from a Demonstration Plant at the GSLP, for distribution into Asia and Oceania and potentially other markets. 

Salt Lake Potash is progressing its GSLP development strategy, initially involving construction of a Demonstration Plant producing up to 50,000tpa of high quality SOP, with its plans to distribute production through a small number of global distribution partnerships.

The Mitsubishi MOU is non-binding and sets out the key terms for a subsequent formal Offtake Agreement as the Demonstration Plant is developed. As well as quantities and target markets, the MOU’s other terms include:

·      Market pricing and commission mechanisms;

·      Specifications and delivery parameters;

·      Mitsubishi to provide strategic advice on marketing within the region; and

·      The parties to continue discussions regarding funding requirements for the GSLP.

Mitsubishi Australia Limited is a wholly owned subsidiary of Mitsubishi Corporation. Mitsubishi is one of the world’s largest trading and investment enterprises that develops and operates businesses across virtually every industry, including industrial finance, energy, metals, machinery, chemicals, and daily living essentials. Its current activities expand far beyond its traditional trading operations to include investments and business management in diverse fields including natural resources development, manufacturing of industrial goods, retail, new energy, infrastructure, finance and new technology-related businesses.

MOU with Australian Potash

In September 2018, Salt Lake entered into a Memorandum of Understanding and Co-operation Agreement with Australian Potash Limited (ASX: APC) to undertake a joint study of the potential benefits of development cost sharing for each Company’s project developments at Lake Wells.

The Companies’ substantial project holdings at Lake Wells are contiguous with many common infrastructure elements, including access roads, proximity to the Leonora rail terminals, and potential power and fresh water solutions. Both Companies anticipate substantial potential Capex and Opex benefits from some level of infrastructure sharing, with further potential benefits arising from shared or common evaporation and salt processing facilities.

The Companies have agreed to constitute a joint study team to carry out an initial assessment of the merits of infrastructure cooperation. The team will also conduct a high-level review of potential benefits of upstream operational synergies. A substantial part of the Study work will be outsourced to independent engineers and both Companies intend to continue with their independent project developments in parallel with the Study.

The Company’s first Mining Lease at Lake Wells was granted in September 2018, a significant milestone in the Projects development pathway.

 

Results of Operations

The net loss of the Consolidated Entity for the year ended 30 June 2018 was $11,327,108 (2017: net loss of $9,200,509). This loss is mainly attributable to:

(i)         Exploration and evaluation expenses of $8,545,647 (2017: $7,717,231) which are attributable to the Group’s accounting policy of expensing exploration and evaluation expenditure incurred by the Group subsequent to the acquisition of the rights to explore and up to the successful completion of definitive feasibility studies for each separate area of interest;

(ii)        Non-cash share-based payment expenses of $1,284,062 (2017: $580,976) which are attributable to the Group’s accounting policy of expensing the value (estimated using an option pricing model) of Incentive Securities issued to key employees and consultants. The value is measured at grant date and recognised over the period during which the option holders become unconditionally entitled to the options and/or rights; and 

(iii)       Business development expenses of $1,110,578 (2017: $559,247) which are attributable to additional business development and investor relations activities required to support the growth and development of the Goldfields Salt Lakes Project, including travel costs associated with representing the Company at international conferences and investor meetings.

 

Financial Position

As at the date of this report, the Company had working capital in excess of $4 million which includes cash and cash equivalents.

At 30 June 2018, the Company had cash reserves of $5,709,446 (2017: $15,596,759).

At 30 June 2018, the Company had net assets of $7,019,989 (2017: $17,046,443), a decrease of 59% compared with the previous year. This decrease is a result of the exploration and evaluation activity during the year, which has been expensed as discussed in the results of operations section above.

 

Business Strategies and Prospects for Future Financial Years 

The objective of the Group is to create long-term shareholder value through the discovery, exploration and development of its projects.

To date, the Group has not commenced production of any minerals. To achieve its objective, the Group currently has the following business strategies and prospects:

(i)      Complete a PFS for the Lake Way Demonstration Plant;

(ii)     Commence construction of the Williamson Ponds at Lake Way and dewatering of Blackham’s Williamson Pit;

(iii)    Commence construction of the on-lake infrastructure and Plant for the Lake Way Demonstration Plant;

(iv)    Complete a PFS on the Lake Wells Project;

(v)     Develop an organic premium SOP product in conjunction with offtake partners and potential customers; and

(vi)    Continue additional exploration activities including drilling, test pumping and other testwork across the Company’s multi lake portfolio.

All of these activities are inherently risky and the Board is unable to provide certainty of the expected results of these activities, or that any or all of these likely activities will be achieved. The material business risks faced by the Group that could have an effect on the Group’s future prospects, and how the Group manages these risks, include:

The Company’s exploration properties may never be brought into production – The exploration for, and development of, mineral deposits involves a high degree of risk. Few properties which are explored are ultimately developed into producing mines. To mitigate this risk, the Company will undertake systematic and staged exploration and testing programs on its mineral properties and, subject to the results of these exploration programs, the Company will then progressively undertake a number of technical and economic studies with respect to its projects prior to making a decision to mine. However there can be no guarantee that the studies will confirm the technical and economic viability of the Company’s mineral properties or that the properties will be successfully brought into production;

The Company’s activities will require further capital – The exploration and any development of the Company’s exploration properties will require substantial additional financing.  Failure to obtain sufficient financing may result in delaying or indefinite postponement of exploration and any development of the Company’s properties or even a loss of property interest. There can be no assurance that additional capital or other types of financing will be available if needed or that, if available, the terms of such financing will be favourable to the Company;

The Company’s licences may be subject to Native title and Aboriginal Heritage – There may be areas over which legitimate common law and/or statutory Native Title rights of Aboriginal Australians exist.  If Native Title rights do exist, the ability of the Company to gain access to the Projects (through obtaining consent of any relevant landowner), or to progress from the exploration phase to the development and mining phases of operations may be adversely affected;

The Company has contractual rights in respect of the Mining Leases on which it plans to build a Demonstration Plant at Lake Way – The Company entered into a Memorandum of Understanding with Blackham in March 2018 that outlines the respective rights and obligations of both parties. The Demonstration Plant will initially be based on Mining Leases held by Blackham and the ability of the Company to proceed with its plans at Lake Way will be dependent on ongoing co-operation with Blackham. The parties intend to formalise arrangements in a Split Commodity Agreement;

The Company’s activities are subject to Government regulations and approvals – Any material adverse changes in government policies or legislation in Western Australia and Australia that affect mining, processing, development and mineral exploration activities, income tax laws, royalty regulations, government subsidies and environmental issues may affect the viability and profitability of any planned development the GSLP. No assurance can be given that new rules and regulations will not be enacted or that existing rules and regulations will not be applied in a manner which could adversely impact the Group’s mineral properties;

The Company may be adversely affected by fluctuations in commodity prices – The price of potash and other commodities fluctuates widely and is affected by numerous factors beyond the control of the Company. Future production, if any, from the Company’s mineral properties will be dependent upon the price of potash and other commodities being adequate to make these properties economic. The Company currently does not engage in any hedging or derivative transactions to manage commodity price risk.  As the Company’s operations change, this policy will be reviewed periodically going forward; and

Global financial conditions may adversely affect the Company’s growth and profitability – Many industries, including the mineral resource industry, are impacted by these market conditions.  Some of the key impacts of the current financial market turmoil include contraction in credit markets resulting in a widening of credit risk, devaluations and high volatility in global equity, commodity, foreign exchange and precious metal markets, and a lack of market liquidity. Due to the current nature of the Company’s activities, a slowdown in the financial markets or other economic conditions may adversely affect the Company’s growth and ability to finance its activities. If these increased levels of volatility and market turmoil continue, the Company’s activities could be adversely impacted and the trading price of the Company’s shares could be adversely affected.

NOTES TO AND FORMING PART OF THE FINANCIAL STATEMENTS
FOR THE YEAR ENDED 30 JUNE 2018

 

1.       STATEMENT OF SIGNIFICANT ACCOUNTING POLICIES

The significant accounting policies adopted in preparing the financial report of Salt Lake Potash Limited (Salt Lake or Company) and its consolidated entities (Consolidated Entity or Group) for the year ended 30 June 2018 are stated to assist in a general understanding of the financial report.

Salt Lake is a Company limited by shares incorporated and domiciled in Australia whose shares are publicly traded on the Australian Securities Exchange (ASX), and the AIM Market (AIM) of the London Stock Exchange.

 

The financial report of the Group for the year ended 30 June 2018 was authorised for issue in accordance with a resolution of the Directors on 26 September 2018.

(a)      Basis of Preparation

The financial report is a general purpose financial report, which has been prepared in accordance with Australian Accounting Standards (“AASBs”) and other authoritative pronouncements of the Australian Accounting Standards Board (“AASB”) and the Corporations Act 2001. The Group is a for-profit entity for the purposes of preparing the consolidated financial statements.

The financial report has been prepared on a historical cost basis. The financial report is presented in Australian dollars.

Going concern 

The consolidated financial statements have been prepared on a going concern basis which assumes the continuity of normal business activity and the realisation of assets and the settlement of liabilities in the ordinary course of business.

For the year ended 30 June 2018, the Consolidated Entity incurred a net loss of $11,327,108 (2017: $9,654,977) and experienced net cash outflows from operating and investing activities of $9,821,628 (2017: $8,586,094). As at 30 June 2018, the Group had cash and cash equivalents of $5,709,446 (2017: $15,596,759) and net current assets of $4,246,901 (2017: $14,515,834).

The Company has recently completed a successful Scoping Study for the Lake Way Demonstration Plant and is currently in the process of finalising parameters for the Pre-Feasibility Study and construction of holding ponds to dewater Blackham’s Williamson Pit. The Scoping Study on the development of a 50,000tpa sulphate of potash (SOP) Demonstration Plant at Lake Way supports a low capex, highly profitable, staged development model. In order to continue to progress the Demonstration Plant at Lake Way and ongoing studies for the wider GSLP, the Company will be required to raise additional capital during the current financial year.

Based on the successful results of the Scoping Study and having previously raised funds for the GSLP, the Directors are confident that they will be able to raise additional capital as and when required to continue to fund operations. In addition, the Directors have been involved in a number of recent successful capital raisings for other listed resource companies, and accordingly, they are satisfied that they will be able to raise additional capital when required to enable the Consolidated Entity to meet its obligations as and when they fall due, and accordingly, consider that it is appropriate to prepare the financial statements on the going concern basis.

Should the Consolidated Entity be unable to raise additional capital as and when required, the Consolidated Entity would need to reduce operational expenditure to continue as a going concern. In the event that the Consolidated Entity is unable to achieve the matters referred to above, uncertainty would exist that may cast doubt on the ability of the Consolidated Entity to continue as a going concern.

These consolidated financial statements do not include any adjustments relating to the recoverability and classification of recorded asset amounts, or to the amounts and classification of liabilities that might be necessary should the Consolidated Entity be unable to continue as a going concern.

(b)      Statement of Compliance

The financial report complies with Australian Accounting Standards and International Financial Reporting Standards (IFRS) as issued by the International Accounting Standards Board.

In the current year, the Group has adopted all of the new and revised Standards and Interpretations issued by the AASB that are relevant to its operations and effective for the current annual reporting period.

New and revised standards and amendments thereof and interpretations effective for the current reporting period that are relevant to the Group include:

 

·           AASB 2016-1 Amendments to Australian Accounting Standards – Recognition of Deferred Tax Assets for Unrealised Losses which clarify that the existence of a deductible temporary difference depends solely on a comparison of the carrying amount of an asset and its tax base at the end of the reporting period, and is not effected by possible future changes in the carrying amount or expected manner of recovery of the asset;

 

·           AASB 2016-2 Amendments to Australian Accounting Standards – Disclosure Initiative: Amendments to AASB 107 which amend existing presentation and disclosure requirements to evaluate changes in liabilities arising from financing activities, including both changes arising from cash flows and non-cash changes; and

 

·           AASB 2017-2 Amendments to Australian Accounting Standards – Further Annual Improvements 2016-2016 Cycle which clarify the existing disclosure requirements and scope of AASB 12 Disclosure of Interest in Other Entities to apply to interests that are classified as held for sale or distribution.

 

The adoption of these new and revised standards has not resulted in any significant changes to the Group’s accounting policies or to the amounts reported for the current or prior periods.

Australian Accounting Standards and Interpretations that have recently been issued or amended but are not yet effective have not been adopted by the Group for the annual reporting period ended 30 June 2018. Those which may be relevant to the Group are set out in the table below.

AASB 16 Leases

1 January 2019

1 July 2019

Management has reviewed the requirements of these accounting standards and has assessed that these will not have any significant impact on the Group’s financial statements based on the following:

·      At 30 June 2018, the Group’s only financial assets and liabilities are cash, receivables, finance lease and payables for which no significant measurement changes have been introduced under AASB 9.  The changes to the impairment model are not anticipated to have an impact on the Group as receivables are primarily comprised of GST and interest;

·      The Group does not currently have any revenue contracts and accordingly AASB 15 is not expected to have an impact on the Group’s results; and

·      The Group’s main operating lease is for office space, currently at a cost of $10,170 per month.  Under AASB 16, an asset (the right to use the leased item) and a financial liability to pay rentals will be recognised. AASB 16 will not apply to short term contracts of less than 12 months.

(c)      Principles of Consolidation

The consolidated financial statements incorporate the assets and liabilities of all subsidiaries of the Company as at 30 June 2018 and the results of all subsidiaries for the year then ended.

Subsidiaries are all entities (including structured entities) over which the group has control. The group controls an entity when the group is exposed to, or has rights to, variable returns from its involvement with the entity and has the ability to affect those returns through its power to direct the activities of the entity.

 

The financial statements of the subsidiaries are prepared for the same reporting period as the Company, using consistent accounting policies. Accounting policies of subsidiaries have been changed where necessary to ensure consistency with the policies adopted by the Company.

 

Subsidiaries are fully consolidated from the date on which control is transferred to the Company. They are de-consolidated from the date that control ceases. Intercompany transactions and balances, income and expenses and profits and losses between Group companies, are eliminated.

(d)      Cash and Cash Equivalents

Cash and cash equivalents include cash on hand, deposits held at call with banks and other short-term highly liquid investments with original maturities of three months or less.

(e)      Trade and Other Receivables

Trade receivables are recognised and carried at the original invoice amount less a provision for any uncollectable debts. An estimate for doubtful debts is made when collection of the full amount is no longer probable. Bad debts are written‑off as incurred.

Short term receivables from related parties are recognised and carried at the nominal amount due and are interest free.

(f)       Investments and Other Financial Assets

(i)       Classification

Financial assets in the scope of AASB 139 Financial Instruments: Recognition and Measurement are classified as either financial assets at fair value through profit or loss, loans and receivables, held-to-maturity investments, or available-for-sale investments, as appropriate. When financial assets are recognised initially they are measured at fair value, plus, in the case of investments not at fair value through profit or loss, directly attributable transaction costs. The Group determines the classification of its financial assets after initial recognition and, when allowed and appropriate, re-evaluates this designation at each financial year-end.

Loans and receivables are non-derivative financial assets with fixed or determinable payments that are not quoted in an active market. They arise when the Group provides money, goods or services directly to a debtor with no intention of selling the receivable. They are included in current assets, except for those with maturities greater than twelve months after the reporting date which are classified as non-current assets. Loans and receivables are included in receivables in the statement of financial position.

 Loans and receivables are carried at amortised cost using the effective interest rate method.

(ii)      Impairment

Collectability of trade and other receivables is reviewed on an ongoing basis. Individual debts that are known to be uncollectible are written off when identified. An impairment allowance is recognised when there is objective evidence that the Consolidated Entity will not be able to collect the receivable. Financial difficulties of the debtor, default payments or debts more than 60 days overdue are considered objective evidence of impairment. The amount of the impairment loss is the receivable carrying amount compared to the present value of estimated future cash flows, discounted at the original effective interest rate.

(g)      Property, Plant and Equipment

(i)       Recognition and measurement

All classes of property, plant and equipment are measured at historical cost.

Plant and equipment is stated at historical cost less accumulated depreciation and any accumulated impairment losses. Such cost includes the cost of replacing parts that are eligible for capitalisation when the cost of replacing the parts is incurred. Similarly, when each major inspection is performed, its cost is recognised in the carrying amount of the plant and equipment as a replacement only if it is eligible for capitalisation. All other repairs and maintenance are recognised in the Statement of Profit or Loss and other Comprehensive Income as incurred.

(ii)      Depreciation and Amortisation

Depreciation is provided on a straight line basis on all property, plant and equipment.

 

2018

2017

Major depreciation and amortisation periods are:

Plant and equipment:

22%- 40%

22%- 40%

The assets’ residual values, useful lives and amortisation methods are reviewed, and adjusted if appropriate, at each financial year end.

(iii)     Derecognition

An item of property, plant and equipment is derecognised upon disposal or when no further future economic benefits are expected from its use or disposal.

(h)      Exploration and Development Expenditure

Expenditure on exploration and evaluation is accounted for in accordance with the ‘area of interest’ method.

Exploration and evaluation expenditure encompasses expenditures incurred by the Group in connection with the exploration for and evaluation of mineral resources before the technical feasibility and commercial viability of extracting a mineral resource are demonstrable.

For each area of interest, expenditure incurred in the acquisition of rights to explore is capitalised, classified as tangible or intangible, and recognised as an exploration and evaluation asset. Exploration and evaluation assets are measured at cost at recognition and are recorded as an asset if:

a.      the rights to tenure of the area of interest are current; and

b.      at least one of the following conditions is also met:

 

·      the exploration and evaluation expenditures are expected to be recouped through successful development and exploitation of the area of interest, or alternatively, by its sale; and

·      exploration and evaluation activities in the area of interest have not at the reporting date reached a stage which permits a reasonable assessment of the existence or otherwise of economically recoverable reserves, and active and significant operations in, or in relation to, the area of interest are continuing.

Exploration and evaluation expenditure incurred by the Group subsequent to acquisition of the rights to explore is expensed as incurred, up to costs associated with the preparation of a feasibility study.

 

(i)    Impairment

Capitalised exploration costs are reviewed each reporting date to establish whether an indication of impairment exists. If any such indication exists, the recoverable amount of the capitalised exploration costs is estimated to determine the extent of the impairment loss (if any). Where an impairment loss subsequently reverses, the carrying amount of the asset is increased to the revised estimate of its recoverable amount, but only to the extent that the increased carrying amount does not exceed the carrying amount that would have been determined had no impairment loss been recognised for the asset in previous years.

Where a decision is made to proceed with development, accumulated expenditure is tested for impairment and transferred to development properties, and then amortised over the life of the reserves associated with the area of interest once mining operations have commenced. Recoverability of the carrying amount of the exploration and evaluation assets is dependent on successful development and commercial exploitation, or alternatively, sale of the respective areas of interest.

(i)       Payables

Liabilities are recognised for amounts to be paid in the future for goods and services received. Trade accounts payable are normally settled within 60 days. Payables are carried at amortised cost.

(j)       Provisions

Provisions are recognised when the group has a legal or constructive obligation, as a result of past events, for which it is probable that an outflow of economic benefits will result and that outflow can be reliably measured.

(k)      Revenue Recognition

Revenue is measured at the fair value of the consideration received or receivable.

Interest income

Interest revenue is recognised on a time proportionate basis that takes into account the effective yield on the financial assets.

(l)       Income Tax

The income tax expense for the period is the tax payable on the current period’s taxable income based on the national income tax rate for each jurisdiction adjusted by changes in deferred tax assets and liabilities attributable to temporary differences between the tax bases of assets and liabilities and their carrying amounts in the financial statements, and to unused tax losses.

Deferred tax assets and liabilities are recognised for temporary differences at the tax rates expected to apply when the assets are recovered or liabilities are settled, based on those tax rates which are enacted or substantively enacted for each jurisdiction. The relevant tax rates are applied to the cumulative amounts of deductible and taxable temporary differences to measure the deferred tax asset or liability. An exception is made for certain temporary differences arising from the initial recognition of an asset or a liability. No deferred tax asset or liability is recognised in relation to these temporary differences if they arose on goodwill or in a transaction, other than a business combination, that at the time of the transaction did not affect either accounting profit or taxable profit or loss.

Deferred tax liabilities and assets are not recognised for temporary differences between the carrying amount and tax bases of investments in controlled entities where the Company is able to control the timing of the reversal of the temporary differences and it is probable that the differences will not reverse in the foreseeable future.

Deferred tax assets are recognised for deductible temporary differences and unused tax losses only if it is probable that future taxable amounts will be available to utilise those temporary differences and losses.

The carrying amount of deferred income tax assets is reviewed at each reporting date and reduced to the extent that it is no longer probable that sufficient taxable profit will be available to allow all or part of the deferred income tax asset to be utilised.

Unrecognised deferred income tax assets are reassessed at each balance date and are recognised to the extent that it has become probable that future taxable profit will allow the deferred tax asset to be recovered.

Current and deferred tax balances attributable to amounts recognised directly in equity are also recognised directly in equity.

Deferred tax assets and deferred tax liabilities are offset only if a legally enforceable right exists to set off current tax assets against tax liabilities and the deferred tax liabilities relate to the same taxable entity and the same taxation authority.

 

Tax consolidation

Salt Lake Potash Limited and its wholly-owned Australian subsidiaries have formed an income tax consolidated group under the tax consolidation regime. Each entity in the group recognises its own current and deferred tax liabilities, except for any deferred tax assets resulting from unused tax losses and tax credits, which are immediately assumed by the Company. The current tax liability of each group entity is then subsequently assumed by the Company. The tax consolidated group has entered a tax sharing agreement whereby each company in the Group contributes to the income tax payable in proportion to their contribution to the net profit before tax of the tax consolidated group.

(m)     Employee Entitlements

Provision is made for the Group’s liability for employee benefits arising from services rendered by employees to balance date. Employee benefits that are expected to be settled within 12 months have been measured at the amounts expected to be paid when the liability is settled, plus related on-costs. Employee benefits expected to be settled more later than 12 months after the year end have been measured at the present value of the estimated future cash outflows to be made for those benefits.

(n)      Earnings per Share

Basic earnings per share (EPS) is calculated by dividing the net profit attributable to members of the Company for the reporting period, after excluding any costs of servicing equity, by the weighted average number of Ordinary Shares of the Company, adjusted for any bonus issue.

Diluted EPS is calculated by dividing the basic EPS earnings, adjusted by the after tax effect of financing costs associated with dilutive potential Ordinary Shares and the effect on revenues and expenses of conversion to Ordinary Shares associated with dilutive potential Ordinary Shares, by the weighted average number of Ordinary Shares and dilutive Ordinary Shares adjusted for any bonus issue.

 

(o)      Goods and Services Tax

Revenues, expenses and assets are recognised net of the amount of GST, except where the amount of GST incurred is not recoverable from the Australian Tax Office. In these circumstances the GST is recognised as part of the cost of acquisition of the asset or as part of the expense. Receivables and payables in the statement of financial position are shown inclusive of GST.

Cash flows are presented in the cash flow statement on a gross basis, except for the GST component of investing and financing activities, which are disclosed as operating cash flows.

(p)      Acquisition of Assets

A group of assets may be acquired in a transaction which is not a business combination. In such cases the cost of the group is allocated to the individual identifiable assets (including intangible assets that meet the definition of and recognition criteria for intangible assets in AASB 138) acquired and liabilities assumed on the basis of their relative fair values at the date of purchase.

(q)      Impairment of Non-Current Assets

The Group assesses at each reporting date whether there is an indication that a non-current asset may be impaired. If any such indication exists, or when annual impairment testing for an asset is required, the Group makes an estimate of the asset’s recoverable amount. An asset’s recoverable amount is the higher of its fair value less costs of disposal and its value in use and is determined for an individual asset, unless the asset does not generate cash inflows that are largely independent of those from other assets or groups of assets and the asset’s value in use cannot be estimated to be close to its fair value. In such cases the asset is tested for impairment as part of the cash-generating unit to which it belongs. When the carrying amount of an asset or cash-generating unit exceeds its recoverable amount, the asset or cash-generating unit is considered impaired and is written down to its recoverable amount.

In assessing the value in use, the estimated future cash flows are discounted to their present value using a pre-tax discount rate that reflects current market assessments of the time value of money and the risks specific to the asset.

An assessment is also made at each reporting date as to whether there is any indication that previously recognised impairment losses may no longer exist or may have decreased. If such indication exists, the recoverable amount is estimated. A previously recognised impairment loss is reversed only if there has been a change in the estimates used to determine the asset’s recoverable amount since the last impairment loss was recognised. If that is the case the carrying amount of the asset is increased to its recoverable amount. That increased amount cannot exceed the carrying amount that would have been determined, net of depreciation, had no impairment loss been recognised for the asset in prior years. Such reversal is recognised in profit or loss. After such a reversal the depreciation charge is adjusted in future periods to allocate the asset’s revised carrying amount, less any residual value, on a systematic basis over its remaining useful life.

(r)      Issued and Unissued Capital

Ordinary Shares are classified as equity. Issued and paid up capital is recognised at the fair value of the consideration received by the Company.

Incremental costs directly attributable to the issue of new shares or options are shown in equity as a deduction, net of tax, from the proceeds.

(s)      Foreign Currencies

(i)         Functional and presentation currency

The functional currency of each of the Group’s entities is measured using the currency of the primary economic environment in which that entity operates. The consolidated financial statements are presented in Australian dollars which is the Company’s functional and presentation currency.

(ii)           Transactions and balances

Foreign currency transactions are translated into functional currency using the exchange rates prevailing at the date of the transaction. Foreign currency monetary items are translated at the year-end exchange rate. Non-monetary items measured at historical cost continue to be carried at the exchange rate at the date of the transaction.

Exchange differences arising on the translation of monetary items are recognised in the Statement Profit or Loss and other Comprehensive Income, except where deferred in equity as a qualifying cash flow or net investment hedge.

Exchange differences arising on the translation of non-monetary items are recognised directly in equity to the extent that the gain or loss is directly recognised in equity, otherwise the exchange difference is recognised in the other Comprehensive Income.

(iii)          Group companies

The financial results and position of foreign operations whose functional currency is different from the Group’s presentation currency are translated as follows:

·           assets and liabilities are translated at year-end exchange rates prevailing at that reporting date;

·           income and expenses are translated at average exchange rates for the period; and

·           items of equity are translated at the historical exchange rates prevailing at the date of the transaction.

Exchange differences arising on translation of foreign operations are transferred directly to the group’s foreign currency translation reserve in the statement of financial position. These differences are recognised in the Statement of Profit or Loss and other Comprehensive Income in the period in which the operation is disposed.

(t)         Share-Based Payments

Equity-settled share-based payments are provided to officers, employees, consultants and other advisors. These share-based payments are measured at the fair value of the equity instrument at the grant date. Fair value is determined using the Binomial option pricing model. Further details on how the fair value of equity-settled share based payments has been determined can be found in Note 20.

The fair value determined at the grant date is expensed on a straight-line basis over the vesting period, based on the Company’s estimate of equity instruments that will eventually vest. At each reporting date, the Company revises its estimate of the number of equity instruments expected to vest. The impact of the revision of the original estimates, if any, is recognised in profit or loss over the remaining vesting period, with a corresponding adjustment to the share based payments reserve.

Equity-settled share-based payments may also be provided as consideration for the acquisition of assets. Where Ordinary Shares are issued, the transaction is recorded at fair value based on the quoted price of the Ordinary Shares at the date of issue. The acquisition is then recorded as an asset or expensed in accordance with accounting standards.

(u)      Use and Revision of Accounting Estimates, Judgements and Assumptions

The preparation of the financial report requires management to make judgements, estimates and assumptions that affect the application of accounting policies and the reported amounts of assets, liabilities, income and expenses. Actual results may differ from these estimates. The estimates and underlying assumptions are reviewed on an ongoing basis. Revisions to accounting estimates are recognised in the period in which the estimate is revised if the revision affects only that period, or in the period of the revision and future periods if the revision affects both current and future periods.

In particular, information about significant areas of estimation uncertainty and critical judgements in applying accounting policies that have the most significant effect on the amounts recognised in the financial statements are described in the following notes:

·              Exploration and Evaluation Expenditure (Note 10)

·              Share-Based Payments (Note 20)

2.       SEGMENT INFORMATION

The Consolidated Entity operates in one operating segment and one geographical segment, being mineral exploration in Australia. This is the basis on which internal reports are provided to the Directors for assessing performance and determining the allocation of resources within the Consolidated Entity.

The benefit of deferred tax assets not brought to account will only be brought to account if:

·      future assessable income is derived of a nature and of an amount sufficient to enable the benefit to be realised;

·      the conditions for deductibility imposed by tax legislation continue to be complied with; and

·      no changes in tax legislation adversely affect the Group in realising the benefit.

Deferred tax assets have not been recognised in respect to tax losses because it is not probable that future taxable profit will be available against which the Group can utilise the benefits.

 

(d)        Tax Consolidation

The Company and its wholly-owned Australian resident entities have formed a tax consolidated group and are therefore taxed as a single entity. The head entity within the tax consolidated group is Salt Lake Potash Limited.

Notes:

(b)        Rights Attaching to Ordinary Shares:

 

The rights attaching to fully paid Ordinary Shares (Ordinary Shares) arise from a combination of the Company’s Constitution, statute and general law.

Ordinary Shares issued following the exercise of Unlisted Options in accordance with Note 14(c) or Performance Shares in accordance with Note 14(d) or Performance Rights in accordance with Note 14(e) will rank equally in all respects with the Company’s existing Ordinary Shares. 

Copies of the Company’s Constitution are available for inspection during business hours at the Company’s registered office. The clauses of the Constitution contain the internal rules of the Company and define matters such as the rights, duties and powers of its shareholders and directors, including provisions to the following effect (when read in conjunction with the Corporations Act 2001 or the listing rules of the ASX and AIM (Listing Rules)).

(i)       Shares

The issue of shares in the capital of the Company and options over unissued shares by the Company is under the control of the Directors, subject to the Corporations Act 2001, ASX Listing Rules and any rights attached to any special class of shares.

(ii)      Meetings of Members

Directors may call a meeting of members whenever they think fit. Members may call a meeting as provided by the Corporations Act 2001. The Constitution contains provisions prescribing the content requirements of notices of meetings of members and all members are entitled to a notice of meeting. A meeting may be held in two or more places linked together by audio-visual communication devices. A quorum for a meeting of members is two shareholders.

The Company holds annual general meetings in accordance with the Corporations Act 2001 and the Listing Rules.

(iii)     Voting

Subject to any rights or restrictions at the time being attached to any shares or class of shares of the Company, each member of the Company is entitled to receive notice of, attend and vote at a general meeting. Resolutions of members will be decided by a show of hands unless a poll is demanded. On a show of hands each eligible voter present has one vote. However, where a person present at a general meeting represents personally or by proxy, attorney or representative more than one member, on a show of hands the person is entitled to one vote only despite the number of members the person represents.

On a poll each eligible member has one vote for each fully paid share held and a fraction of a vote for each partly paid share determined by the amount paid up on that share.

(iv)     Changes to the Constitution

The Company’s Constitution can only be amended by a special resolution passed by at least three quarters of the members present and voting at a general meeting of the Company. At least 28 days’ written notice specifying the intention to propose the resolution as a special resolution must be given.

(v)      Listing Rules

Provided the Company remains admitted to the Official List of the ASX, then despite anything in its Constitution, no act may be done that is prohibited by the Listing Rules, and authority is given for acts required to be done by the Listing Rules. The Company’s Constitution will be deemed to comply with the Listing Rules as amended from time to time.

22.     FINANCIAL RISK MANAGEMENT OBJECTIVES AND POLICIES

(a)        Overview

The Group’s principal financial instruments comprise receivables, payables, finance leases, cash and short-term deposits. The main risks arising from the Group’s financial instruments are credit risk, liquidity risk and interest rate risk.

This note presents information about the Group’s exposure to each of the above risks, its objectives, policies and processes for measuring and managing risk, and the management of capital. Other than as disclosed, there have been no significant changes since the previous financial year to the exposure or management of these risks.

The Group manages its exposure to key financial risks in accordance with the Group’s financial risk management policy. Key risks are monitored and reviewed as circumstances change (e.g. acquisition of a new project) and policies are revised as required. The overall objective of the Group’s financial risk management policy is to support the delivery of the Group’s financial targets whilst protecting future financial security.

Given the nature and size of the business and uncertainty as to the timing and amount of cash inflows and outflows, the Group does not enter into derivative transactions to mitigate the financial risks. In addition, the Group’s policy is that no trading in financial instruments shall be undertaken for the purposes of making speculative gains. As the Group’s operations change, the Directors will review this policy periodically going forward.

The Board of Directors has overall responsibility for the establishment and oversight of the risk management framework. The Board reviews and agrees policies for managing the Group’s financial risks as summarised below.

 

(b)        Credit Risk

Credit risk is the risk of financial loss to the Group if a customer or counterparty to a financial instrument fails to meet its contractual obligations. This arises principally from cash and cash equivalents and trade and other receivables.

There are no significant concentrations of credit risk within the Group. The carrying amount of the Group’s financial assets represents the maximum credit risk exposure, as represented below:

15,596,759

Trade and other receivables

227,273

300,058

5,936,719

15,896,817

 

With respect to credit risk arising from cash and cash equivalents, the Group’s exposure to credit risk arises from default of the counter party, with a maximum exposure equal to the carrying amount of these instruments. Where possible, the Group invests its cash and cash equivalents with banks that are rated the equivalent of investment grade and above. The Group’s exposure and the credit ratings of its counterparties are continuously monitored and the aggregate value of transactions concluded is spread amongst approved counterparties.

The Group does not have any significant customers and accordingly does not have significant exposure to bad or doubtful debts.

Trade and other receivables comprise interest accrued and GST refunds due. Where possible the Consolidated Entity trades only with recognised, creditworthy third parties. Receivable balances are monitored on an ongoing basis with the result that the Group’s exposure to bad debts is not significant. At 30 June 2018, none (2017 none) of the Group’s receivables are past due.

(c)        Liquidity Risk

 

Liquidity risk is the risk that the Group will not be able to meet its financial obligations as they fall due. The Board’s approach to managing liquidity is to ensure, as far as possible, that the Group will always have sufficient liquidity to meet its liabilities when due. At 30 June 2018 and 2017, the Group had sufficient liquid assets to meet its financial obligations.

The contractual maturities of financial liabilities, including estimated interest payments, are provided below. There are no netting arrangements in respect of financial liabilities.

(d)        Interest Rate Risk

 

The Group does not have any long-term borrowing or long term deposits, which would expose it to significant cash flow interest rate risk.

The Group currently does not engage in any hedging or derivative transactions to manage interest rate risk.

(e)        Capital Management

The Group defines its Capital as total equity of the Group, being $7,019,989 as at 30 June 2018 (2017: $17,046,443). The Group manages its capital to ensure that entities in the Group will be able to continue as a going concern while financing the development of its projects through primarily equity based financing. The Board’s policy is to maintain a strong capital base so as to maintain investor, creditor and market confidence and to sustain future development of the business. Given the stage of development of the Group, the Board’s objective is to minimise debt and to raise funds as required through the issue of new shares.

The Group is not subject to externally imposed capital requirements.

There were no changes in the Group’s approach to capital management during the year. During the next 12 months, the Group will continue to explore project financing opportunities, primarily consisting of additional issues of equity.

(f)         Fair Value

The Group uses various methods in estimating the fair value of a financial instrument. The methods comprise:

·      Level 1 – the fair value is calculated using quoted prices in active markets.

·      Level 2 – the fair value is estimated using inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly (as prices) or indirectly (derived from prices).

·      Level 3 – the fair value is estimated using inputs for the asset or liability that are not based on observable market data.

At 30 June 2018 and 30 June 2017, the carrying value of the Group’s financial assets and liabilities approximate their fair value.

8.     MINERAL RESOURCES STATEMENT 

Salt Lake’s Mineral Resource Statement as at 30 June 2018 is grouped by deposit, all of which form part of the Lake Wells SOP in Western Australia. To date, no Ore Reserves have been reported for these deposits. Subsequent to 30 June 2018, the Company reported a Mineral Resource Estimate for Lake Way.  The Lake Way Mineral Resource does not form part of this statement.

Governance

The Company engages external consultants and Competent Persons (as determined pursuant to the JORC Code 2012) to prepare and estimate the Mineral Resources. Management and the Board review these estimates and underlying assumptions for reasonableness and accuracy. The results of the Mineral Resource estimates are then reported in accordance with the requirements of the JORC Code 2012 and other applicable rules (including ASX Listing Rules).

Where material changes occur during the year to the project, including the project’s size, title, exploration results or other technical information, previous resource estimates and market disclosures are reviewed for completeness.

The Company reviews its Mineral Resources as at 30 June each year. A revised Mineral Resource estimate will be prepared as part of the annual review process where a material change has occurred in the assumptions or data used in previously reported Mineral Resources. However, there are circumstances where this may not be possible (e.g. an ongoing drilling programme), in which case a revised Mineral Resource estimate will be prepared and reported as soon as practicable.

Results of Annual Review

In November 2015, the Company reported its maiden JORC Mineral Resource estimate for the Lake Wells Project, totalling 29 million tonnes (Mt) of Sulphate of Potash (SOP) with approximately 80% in the ‘Measured’ category with excellent brine chemistry of 4,009 mg/L Potassium (K), 19,175 mg/L (SO4). The resource was calculated only on the upper 16 metres of the Lake, with mineralisation remaining open at depth across most of the Lake.

In February 2016, an expanded Mineral Resource Estimate (MRE) was calculated at Lake Wells totalling 80-85 million tonnes of SOP. This represents an additional 51-56 Mt of Inferred Resource calculated in the strata below the previously reported shallow Resource of 29 Mt.

During the year ended 30 June 2018, the Company continued exploration and development activities for Lake Wells including surface aquifer characterisation (test pits and trenches), deep aquifer exploration, long term pump testing, evaporation pond trials and process testwork.

In addition, in March 2018, the Company released an initial estimate of Exploration Targets for eight of the nine lakes comprising the GSLP. The ninth lake, Lake Wells (as discussed above) already has a Mineral Resource reported in accordance with the JORC code.

The total “stored” Exploration Target for the GSLP is 290Mt – 458Mt of contained SOP, with an average SOP grade of 4.4 – 7.1kg/m3 (including Lake Wells’ Mineral Resource of 80-85Mt). On a “drainable” basis the total Exploration Target ranges from 26Mt – 153Mt of SOP.  The total playa area of the lakes is approximately 3,312km2. The potential quantity and grade of this Exploration Target is conceptual in nature. There has been insufficient exploration to estimate a Mineral Resource and it is uncertain if further exploration will result in the estimation of a Mineral Resource.

As a result of the annual review of the Company’s Mineral Resources, there has been no change to the Mineral Resources reported for the Lake Wells Project in February 2016 as at 30 June 2018.

Salt Lake Potash #SO4 & Australian Potash ASX: #APC to Study Benefits of Cost Sharing at Lake Wells

Salt Lake Potash#SO4 & Australian Potash ASX: #APC to Study Benefits of Cost Sharing at Lake Wells

Highlights:

  • Salt Lake Potash Limited (ASX/AIM: SO4) and Australian Potash Limited (ASX: APC) have entered into a Memorandum of Understanding and Co-operation Agreement to study the potentially very substantial benefits of sharing infrastructure and other costs at Lake Wells
  • The Companies will conduct a joint study into the merits of developing aspects of their respective Lake Wells projects together (the ‘Study’)
  • The Study will initially focus on a shared costs model around infrastructure developments
  • The Study will also address at a high-level the potential for cost sharing on common evaporation and salt processing developments
  • Both Companies’ projects at Lake Wells will proceed independently in parallel with the Study with no impact on either Company’s timelines

Salt Lake Potash Limited (ASX/AIM: SO4) and Australian Potash Limited (ASX: APC) are pleased to advise that the Companies have entered into a Memorandum of Understanding and Co-operation Agreement to undertake a joint study of the potential benefits of development cost sharing for each Company’s project developments at Lake Wells.

The Companies’ substantial project holdings at Lake Wells are contiguous with many common infrastructure elements, including access roads, proximity to the Leonora rail terminals, and potential power and fresh water solutions. Both Companies anticipate substantial potential Capex and Opex benefits from some level of infrastructure sharing, with further potential benefits arising from shared or common evaporation and salt processing facilities.

A paleochannel extending in excess of 140 kilometres traverses the Companies combined tenement holding over Lake Wells. Recently both APC and SO4 have been granted initial Mining Leases over their respective projects at Lake Wells.

APC’s scoping study released in March 2017 indicated a staged development producing 150,000 tpa rising to 300,000 tpai of premium grade Sulphate of Potash (SOP) from its stand-alone development. APC has a 2012 JORC Mineral Resource Estimate (calculated from drainable porosity) of 14.7 Mti of SOP (derived from a total of 72 Mt contained in total porosity).

SO4’s scoping study released in August 2016 indicated a staged development producing 200,000 tpa rising to 400,000 tpa on a fully ramped basis. SO4 has reported a total JORC Mineral Resource at Lake Wells of 80-85 Mt of SOP (Stored Resource).

Logistics and Infrastructure

Each Company’s project is based on heavy haulage road transport from Lake Wells to the rail head at either Malcolm (280kms) or Leonora (300kms), utilising the same haulage route. There is compelling logic in pursuing the economies of scale inherent in a (larger) shared solution as well as sharing the capital costs for road upgrades, haulage equipment and other transport and handling facilities. There is similar synergy potential in shared power, air transport, accommodation and process water costs.

Both projects have very similar brine chemistry given they are essentially hosted on the same paleochannel. Naturally they will also experience the same climatic conditions, meaning the process flowsheets for each project should be very similar. This offers the opportunity for potential additional savings by a co-operative arrangement extending to evaporation and salt processing facilities.

The Companies have agreed to constitute a joint study team to carry out an initial assessment of the merits of infrastructure cooperation. The team will also conduct a high-level review of potential benefits of upstream operational synergies. A substantial part of the Study work will be outsourced to independent engineers and both Companies intend to continue with their independent project developments in parallel with the Study.

Stockhead – Potash stock guide: how the Pilbara could help feed the world

The Pilbara region of Western Australia is best known for iron ore — and in more recent times goldand lithium.

But a group of pioneering ASX companies reckon it also has the potential to be a major hub for potash — a mineral salt that’s critical in plant, animal and human life.

There are some 30 ASX-listed companies active in potash, but it is not a well-understood industry.

Over the past year, 16 of 28 potash-related stocks tracked by Stockhead have made gains of 4 per cent to 263 per cent.

Potash comes from salts that contain potassium in water soluble form. It is used as a fertiliser.

There are two commonly used fertilisers – muriate of potash (MOP) and sulphate of potash (SOP).

MOP is the most common (around 90 per cent of the world’s potash) and is used on a variety of crops. However, the more chloride-sensitive crops like avocados, coffee beans and cocoa require SOP – which fetches $US270 per tonne more than MOP.

The global potash market is estimated to be around 75 million tonnes.

Demand is set to increase as the global population grows to around 8 billion by 2023.

Greg Cochran, the boss of Pilbara potash explorer Reward Minerals (ASX:RWD) told Stockhead an extra 100,000 to 150,000 tonnes of potash will be required each year.

Right now Australia imports all its potash from Canada, the Middle East and Europe. Australia’s MOP and SOP consumption is around 250,000 tonnes each year.

China and big plantation-focused countries in southeast Asia – like Malaysia and Indonesia – are expected to be the key contributors to demand growth.

The potash market is perhaps one of the most stable compared to other commodities, with the price difference between MOP and SOP remaining close to $US270 per tonne for the past three years.

Pilbara could rival world’s largest potash exporter 

Reward Minerals' Lake Disappointment sulphate of potash project.

Reward believes the Pilbara could become the next Saskatchewan – a region in Canada that is currently the world’s largest exporter of potash.

Canada produced 12 million tonnes of potash last year and the bulk of that came from Saskatchewan.

Mr Cochran said director Michael Ruane saw the potential of the Pilbara early on.

“Mick saw it first, where he said: ‘this has the potential to be the next Saskatchewan’,” Mr Cochran said.

“That’s the potash potential of this broader region in which we operate up here [the Pilbara], and with the climatic conditions it’s ideal and it’s a lot closer than Saskatchewan is to Vancouver.”

Saskatchewan is nearly 1700km from Vancouver.

By comparison, Reward’s Lake Disappointment project is less than 900km from Port Hedland – which is where the company is planning to ship its SOP product from.

“I’m not talking just about Lake Disappointment, but other projects further inland, and we’ve got some really good insights into the geological potential that we as a company have learnt over the last 12 years,” Mr Cochran said.

“In fact, when we talk to government ministers that’s part of the conversation. There’s a dream there, this vision is big.”

A recent pre-feasibility study indicated Reward’s Lake Disappointment project will produce 9 million tonnes of SOP over a 27-year life.

One of the evaporation ponds at Reward Minerals' Lake Disappointment project.

Reward says it will be one of the world’s largest and longest-life brine SOP projects.

The who’s who of potash

Australia does not currently produce any of its own potash, but the bulk of the production will eventually come from WA.

Kalium Lakes (ASX:KLL) this week announced it has increased the measured and indicated resources for its flagship Beyondie SOP project in WA by 150 per cent.

This is expected to translate into a “substantial increase” in ore reserves, which is also due for an update this month, managing director Brett Hazelden told investors earlier this week.

Kalium’s share price has jumped 31 per cent to 46.5c since this time last year.

The Beyondie project currently has enough in reserves to mine 75,000 tonnes each year for more than 23 years.

Kalium is the closest to production, having already been granted the necessary mining licence and received approval for its mining proposal and mine closure plan.

The company expects to be able to start early construction works this year.

Kalium is also in a joint venture with BCI Minerals (ASX:BCI) on the Carnegie potash project, which is located about 220km east-north-east of Wiluna.

BCI diversified into salt, SOP and gold following the steep drop in iron ore price.

The company, which was once known as BC Iron, has witnessed a 15.6 per cent drop in its share price over the past year and is trading around 13.5c.

BCI is now selling off its Pilbara iron ore projects after it sunk to a $16.9 million loss in FY18.

The company can earn up to a 50 per cent interest in the Carnegie project by sole-funding exploration and development expenditure across several stages.

The Carnegie project lies directly north of Salt Lake Potash’s (ASX:SO4) Lake Wells project and Australian Potash’s (ASX:APC) project, which is also named Lake Wells.

Salt Lake also has another project near Wiluna called Lake Way.

From MiningNews.net – Salt Lake #SO4 promotes Lake Way demonstration numbers

Salt Lake promotes Lake Way demonstration numbers

SALT Lake Potash has outlined a demonstration-style development in Western Australia that could cost A$50 million to build and be capable of yielding 50,000 tonnes per product selling for about $667 per tonne at a cost of $387/t FOB.

Notionally at least, such a margin would generate annual cashflow at an operational level of $14 million per annum.

The demonstration project at Lake Way is based on previously mined gold open pits at Lake Way near Wiluna containing super-saturated brine, and is intended to validate the technical and commercial viability of large scale brine SOP production of 400,000 tonnes per annum.

Salt Lake Potash believes a full scale project development – at Lake Wells, east of Wiluna – could produce at operating costs of $185/t FOB.

Assuming positive feasibility work Salt Lake Potash’s objective is to produce initial harvest salts in mid-late 2019 for initial SOP production in early 2020, subject to permitting, weather and other parameters.

Salt Lake Potash #SO4 – Scoping Study For Low Capex, High Margin Demonstration Plant At Lake Way

Salt Lake Potash Limited (SO4) is pleased to announce that a Scoping Study on development of a 50,000tpa sulphate of potash (SOP) Demonstration Plant at Lake Way supports a low capex, highly profitable, staged development model, with total capital costs of approximately A$49m and average cash operating costs (FOB) of approximately A$387/t.

Cautionary Statement

The Scoping Study referred to in this announcement has been undertaken to determine the potential viability of a Demonstration Plant constructed at the Lake Way Project (Project) and to reach a decision to provide a basis for proceeding with more definitive studies. The Scoping Study has been prepared to an accuracy level of ±30%. The results should not be considered a profit forecast or production forecast.

The Scoping Study is a preliminary technical and economic study of the potential viability of the Lake Way Project. In accordance with the ASX Listing Rules, the Company advises it is based on low-level technical and economic assessments that are not sufficient to support the estimation of ore reserves. Further evaluation work including infill drilling and appropriate studies are required before Salt Lake Potash will be able to estimate any ore reserves or to provide any assurance of an economic development case.

100% of the total production target is in the Indicated and Measured resource category.

The Scoping Study is based on the material assumptions outlined elsewhere in this announcement. These include assumptions about the availability of funding. While Salt Lake Potash considers all the material assumptions to be based on reasonable grounds, there is no certainty that they will prove to be correct or that the range of outcomes indicated by the Scoping Study will be achieved.

To achieve the range outcomes indicated in the Scoping Study, additional funding will likely be required. Investors should note that there is no certainty that Salt Lake Potash will be able to raise funding when needed. It is also possible that such funding may only be available on terms that dilute or otherwise affect the value of the Salt Lake Potash’s existing shares. It is also possible that Salt Lake Potash could pursue other ‘value realisation’ strategies such as sale, partial sale, or joint venture of the Project. If it does, this could materially reduce Salt Lake Potash’s proportionate ownership of the Project.

The Company has concluded it has a reasonable basis for providing the forward looking statements included in this announcement and believes that it has a reasonable basis to expect it will be able to fund the development of the Project. Given the uncertainties involved, investors should not make any investment decisions based solely on the results of the Scoping Study.

The Demonstration Plant will initially be based on Mining Leases owned by Blackham Resources Limited, under the Memorandum of Understanding (MOU) described in the ASX Announcement dated 12 March 2018.

Longer term and larger volume production will be based on SLP’s Lake Way exploration permits.

Timeline:

The Company’s objective is to produce initial harvest salts in mid-late 2019 for initial SOP production in early 2020, subject to permitting, weather and other parameters. 

There are potentially considerable time savings from utilising the super-saturated brines in the Williamson Pit at Lake Way and testwork continues to define these parameters.

DEVELOPMENT PROCESS

The Demonstration Plant is intended to validate the technical and commercial viability of brine SOP production from the Company’s Goldfields Salt Lakes Project (GSLP), providing the basis to build a world class, low cost, long life SOP operation across the 9 lakes in the GSLP.

The Company has previously established that larger production volumes (400,000tpa) can result in operating costs in the lowest cost quartile for SOP production globally*. This is principally a result of the economies of scale inherent in the GSLP’s advantageous location in the Northern Goldfields mining district, mostly in the main cost centres of transport, labour and power.

The Company will pursue a fast track, staged approach to the development of a Demonstration Plant at Lake Way, taking advantage of the unique circumstances of the Williamson Pit to accelerate the development timeline, while also de-risking the project at each stage.

Pursuant to the MOU with Blackham Resources Ltd (Blackham), the Company will construct an initial pond system to dewater the Williamson Pit, which contains approximately 1.2GL of super-saturated brine, with a very high average SOP content of 25kg/m3. These Williamson Ponds will comprise approximately 1/3 of the total Demonstration Plant pond area, and early dewatering of the Williamson Pit offers a much shorter development time due to its very high grade and saturation.

SLP plans to construct the Williamson Ponds by the end of 2018, in parallel with completing a Feasibility Study for the Demonstration Plant, followed by initial kainite salt harvesting in mid-late 2019.

After the Feasibility Study, the Company anticipates completing the balance of the on-lake infrastructure – evaporation ponds and trenches – while the fabrication of the process plant is completed offsite. Stockpiled kainite harvest salt will be used for commissioning when the plant is installed, also on existing Mining Leases, with the Company planning for initial SOP production in early 2020, subject to weather, permitting and other factors.

LONGER TERM OUTLOOK

The excellent economic parameters support the development of a Demonstration Plant on the Blackham Mining Leases at Lake Way, which would likely be followed by expanded production onto SLP’s current Exploration Permits, covering most of the Lake and including the paleochannel identified by previous exploration.

Expansion of production beyond the Demonstration Plant would capture substantial economies of scale inherent in bulk transport, reduced royalties and spreading the fixed cost base, amongst other things.

The Company has previously estimated Exploration Targets for the whole of Lake Way ranging from 28-54Mt of SOP (stored) and 3-19Mt (drainable), indicating potential for the Lake to support a much larger SOP operation. [The potential quantity and grade of this Exploration Target is conceptual in nature. There has been insufficient exploration to estimate a Mineral Resource and it is uncertain if further exploration will result in the estimation of a Mineral Resource].

Following demonstration of the viability of SOP production in the GSLP the Company plans to expand production to the other lakes, which have broadly similar salt production potential and transport solutions in some cases superior to Lake Way. The company is investigating integrated production scenarios across a number of lakes, ranging from centralised processing of intermediate concentrates to centralised stockpiling, transport staging, packaging and logistics.

As production volumes increase, particularly to the lakes south of Lake Way, the optimal transport solution is likely to be based on bulk rail haulage from Leonora or Malcolm sidings, through Kalgoorlie to port. Transport and handling is the largest cost centre for SOP production, and there is substantial potential to capture economies of scale from this logistics solution.

The Company has been in discussion with a range of parties about potential financing structures for a Demonstration Plant on the GSLP, including debt, equity, off-take, royalty and joint venture structures. The Company is well funded to continue Feasibility Study work while these discussions continue.

The Company is in the process of drafting a formal agreement with Blackham, in accordance with the MOU. Both parties currently anticipate dewatering of the Williamson Pit in late 2018/early 2019.

CEO Matt Syme said “This Scoping Study confirms our expectations that a Demonstration Plant at Lake Way is the ideal model for starting development of the broader SOP project across our extensive salt lake portfolio. The advantages inherent in our location and the cost benefits associated with low cost trench extraction and on-lake ponds are apparent, and these advantages will increase significantly with scale. The low capex, excellent operating margins and ability to de-risk the Project through staged development also give us the opportunity to optimise the numerous financing alternatives before us.  We are excited to be at the leading edge of a whole new industry in Australia and we are looking forward to developing the most sustainable and rewarding fertiliser project in the world.”

BACKGROUND

SLP is the owner of the Goldfields Salt Lakes Project (GSLP), which comprises nine large salt lakes in the Northern Goldfields Region of Western Australia.

The GSLP has a number of important, favourable characteristics:

Ø  Very large paleochannel hosted brine aquifers, with chemistry amenable to evaporation of salts for SOP production, extractable from both low-cost trenches and deeper bores;

Ø  Over 3,300km2 of playa surface, with in-situ clays suitable for low cost on-lake pond construction;

Ø  The total “stored” Exploration Target for the GSLP is 290Mt – 458Mt of contained Sulphate of Potash (SOP) with an average SOP grade of 4.4 – 7.1kg/m3 (including Lake Wells’ Mineral Resource of 80-85Mt). On a “drainable” basis the total Exploration Target ranges from 26Mt – 153Mt of SOP. [The potential quantity and grade of this Exploration Target is conceptual in nature. There has been insufficient exploration to estimate a Mineral Resource and it is uncertain if further exploration will result in the estimation of a Mineral Resource].

Ø  Excellent evaporation conditions;

Ø  Excellent access to transport, energy and other infrastructure in the Goldfields mining district;

Ø  Lowest quartile capex and opex potential based on the Lake Wells Scoping Study;

Ø  Clear opportunity to reduce transport costs by developing lakes closer to infrastructure and by capturing economies of scale;

Ø  Multi-lake production offers operational flexibility, cost advantages and risk mitigation from localised weather events;

Ø  The very high level of technical validation already undertaken at Lake Wells substantially applies to the other lakes in the GSLP; and

Ø  Potential co-product revenues, particularly where transport costs are lowest.

The Company’s long term plan is to develop an integrated SOP operation of global scale producing high quality organic SOP from a number (or all) of the lakes within the GSLP, after confirming the technical and commercial elements of the Project through construction and operation of a Demonstration Plant producing up to 50,000tpa of SOP.

DEMONSTRATION PLANT

The Company believes the advantages of the Demonstration Plant approach are:

·     While substantial salt-lake brine production of SOP is undertaken in China, Chile and the USA, it is new in Australia and overseas production models need to be tested and adapted for Australian conditions.

·     Proof of concept for SOP production from salt-lake brines in Australia will substantially de-risk the full-scale project, with commensurate improvement in financing costs and alternatives. While the Demonstration Plant does not benefit from economies of scale, it will provide financiers and partners a very reliable cost basis for larger scale, longer term operations, while still being low capex and high margin in its own right.

·     Refinement of design and costing of engineering elements at Demonstration Plant scale should result in considerable time and cost savings at larger scale.

·     Market acceptance of a new product in conservative agricultural markets is best achieved progressively and in conjunction with existing, established partner(s). It is important to establish SLP’s product(s) as premium, sustainable nutrients in the key long-term markets, and staged production increments are the best way to achieve this objective.

·     A Demonstration Plant offers an accelerated pathway to initial production, with limited infrastructure requirements and a faster, simpler approval process. The Demonstration Plant is intended to operate for 12-24 months to establish parameters for larger scale production, and then be integrated into a larger operation. The Company’s objective is to commence construction in 2018, harvesting first salts in 2019, and producing first SOP in early 2020.

LAKE WAY

The Company’s recent Memorandum of Understanding with Blackham Resources Limited (see ASX Announcement dated 12 March 2018) offers the potential for an expedited path to development at Lake Way, possibly the best site for a 50,000tpa Demonstration Plant in Australia.

Lake Way is located less than 15km south of Wiluna. The Wiluna region is an historic mining precinct dating back to the late 19th century. It has been a prolific nickel and gold mining region with well developed, high quality infrastructure in place.

The Goldfields Highway is a high quality sealed road permitted to carry quad road trains and passes 2km from the Lake. The Goldfields Gas Pipeline is adjacent to SLP’s tenements, running past the eastern side of the Lake.

Lake Way has some compelling advantages which make it potentially an ideal site for an SOP operation, including:

·        Substantial capital and operating savings potential from sharing overheads and infrastructure with the Wiluna Gold Mine. This includes the accommodation camp, flights, power, maintenance, infrastructure and other costs.

·        The site has an excellent freight solution, located 2km from the Goldfields Highway, which is permitted for heavy haulage 4 trailer road trains to the railhead at Leonora or by road to Geraldton. It is also adjacent to the Goldfields Gas Pipeline.

·        A Demonstration Plant would likely be built on Blackham’s existing Mining Licences.

·        SLP would dewater the Williamson Pit, prior to Blackham mining, planned for early-mid 2019. The pit contains an estimated 1.2GL of brine at the exceptional grade of 25kg/m3 of SOP. This brine is potentially the ideal starter feed for evaporation ponds, having already evaporated from the normal Lake Way brine grade, which averages around 14kg/m3.

·        The high grade brines at Lake Way will result in lower capital and operating costs due to lower extraction and evaporation requirements.

·        Historical exploration and initial sampling indicate the presence of clays in the upper levels of the lake which should be amenable to low cost, on-lake evaporation pond construction.

PROJECT OVERVIEW

The Demonstration Plant will produce up to 50,000tpa of high quality, standard SOP from hypersaline brine extracted from Lake Way via a system of shallow trenches.

The extracted brine will be transported to a series of solar evaporation ponds built on the Lake where selective evapo-concentration will precipitate potassium double salts in the final evaporation stage. These potassium-rich salts will be mechanically harvested and processed into SOP in a separation and crystallisation plant. The final product will then be transported for sale to the domestic and international markets.

The Company has previously tested and verified at Lake Wells all the major technical foundations for production of SOP from salt lake brine under actual site conditions and across all seasons. These technical achievements are broadly applicable across all the lakes in the GSLP and form part of the inputs into the Scoping Study.

The Study has established the indicative costs of the Demonstration Plant to +/- 30% accuracy for Operating Costs and -10%/+30% for Capital Expenditure.

PROJECT GEOLOGY AND RESOURCE

Geological Setting

The investigation area is in the Northern Goldfields Province on the Archaean Yilgarn Craton. The province is characterised by granite-greenstone rocks that exhibit a prominent northwest tectonic trend and low to medium-grade metamorphism. The Archaean rocks are intruded by east-west dolerite dykes of Proterozoic age, and in the eastern area there are small, flat-lying outliers of Proterozoic and Permian sedimentary rocks. The basement rocks are generally poorly exposed owing to low relief, extensive superficial cover, and widespread deep weathering. 

A key feature of the Goldfields is the presence of paleochannel aquifers.  Palaeochannels are former deep river valleys that eroded into the bedrock within the broad palaeodrainages the sedimentary sequence in the northern goldfields is approximately 130m thick comprising basal Eocene sand overlain by plastic clay, which is in turn concealed by the lakebed sediments and surface alluvial cover.

The stratigraphy of the lake and paleochannel system is described below

Lake Bed Sediments

The hydrogeology of Lake Way is that of a terminal groundwater sink. The large area of the playa and the shallow water table observed at all sites beneath the playa will facilitate evaporative loss. The brine potash resource extends the full depth of the lakebed sediments, with higher permeability noted at the weathered bedrock contact.

The Lake bed sediments are dominated by red-brown lacustrine clays. Logging and observation of the stratigraphy from the test pits indicated that multiple paleosurfaces are evident within the lake sediments, with characteristics very similar to the current lacustrine and fringing environments. 

Moving east from the lake edge the sedimentary sequence consists of clean, evaporitic sands, beneath the surface sands there is evidence of vegetated type paleosurfaces. These surfaces are characterised by thin beds of dark brown to black (organic enriched) evaporitic sands overlying lacustrine clays with abundant remnant root channels. 

Beneath these the sandy silty clays are firm to hard and notably competent.

The lakebed sediments in the vicinity of the Williamson pit are approximately 3 – 4m thick, they were initially dewatered prior to mining and have remained dry since. Test pits excavated within the dewatered zone had a water level 2.5mbgl after 24 hours.

Paleochannel Sediments

The paleochannel sediments are overlain by the brine rich Lacustrine sequence. The paleochannel sediments are dominated by dense grey and redbrown clays. These clays have a low permeability and are not considered a principal source of brine. At the base of the clays there is a high permeability basal sand aquifer. 

Paleochannel Basal Sand Aquifer

Drilling conducted by AGC Woodward Clyde (1992)1 on behalf of WMC Ltd in the early 1990’s located a Tertiary paleochannel beneath the eastern margins of the lakebed outside Blackham’s Mining Leases, the basal sands within the paleochannel were observed to be 20 – 40m thick. The hydrochemistry of the paleochannel water is high in Potassium, Magnesium sulphate and therefore represents a prospective exploration target and future source of brine, it is not included within the current resource estimate.

Basement

The shallowness of sediments, particular to the west of the WIllaimson pit and the island, means that the weathered basement is at excavatable depths. Further to the east the lakebed sequence thickens to depth approaching 15 – 20m. Basement geology is complex with mafic, felsic and metasedimentary rocks existing in multiple, thin, NNW-SSE trending lineations along with an abundance of (often, recently activated) faults. Brine flows from basement contacts is highly variable but, in places, can be very rapid. 

Williamson Pit

There is a significant brine resource within the Williamson Pit. The top of the brine sits approximately 30m below ground level (bgl). There is only minor evidence of inflow from above the standing brine level from either the bedrock or the lakebed sediments. 

The annual sequence of seepage and rainfall followed by evaporation has, over the past 10 years since the pits closure, concentrated the salts to the point where they are almost twice the concentration than the brine contained within the lakebed sediments.

MINERAL RESOURCE

The Lake Way Mineral Resource (Blackham tenements only) was estimated by Groundwater Science Pty Ltd, an independent hydrogeological consultant with substantial salt lake brine expertise.

The Mineral Resource Estimate (MRE) underpinning the production target, classified as Indicated and Measured, was prepared by a Competent Person and is reported in accordance with the JORC Code (2012 Edition) in this announcement.

Hydrology Summary 

The Lake Way catchment as defined using Geoscience Australia’s 1 second DEM and MapInfo Discover Hydrology Package, the catchment area is 3,767 km2.

A runoff model was developed for the Lake Way Catchment using the WaterCress software package. The model was constructed and calibrated to the adjacent and analogous Gascoyne River catchment, and then run using the catchment area defined for Lake Way and rainfall data from the Wiluna BOM station. Average calculated annual run-off is 3.9% of annual rainfall but is highly variable.

The morphology of the playa shape and surface is consistent with the classification system described by Bowler, (1986). The Northern part of the Playa exhibits morphology typical of significant surface water influence and periodic inundation (smooth playa edges, one island). The southern part of the playa exhibits morphology consistent with a groundwater dominated playa with rare inundation (irregular shoreline, numerous islands).

Exploration History

Significant historical exploration work has been completed in the Lake Way area focusing on nickel, gold and uranium. The Company has reviewed multiple publicly available documents including relevant information on the Lake Way’s hydrogeology and geology.  

A review of the Department of Mines and Petroleum’s WAMEX database was undertaken. The database contains more than 6,200 mineral exploration drill holes across the Lake Way region, with about 1,000 drill holes within the Blackham Mining Lease area above.

Recent Exploration Activities

A comprehensive surface aquifer exploration program was completed on the Blackham Mining Leases, comprising a total of 36 shallow test pits and 2 test trenches. This work provides preliminary data for the geological and hydrological models of the surface aquifer of the Lake and was used in the establishment of the Mineral Resource for Lake Way’s surface aquifer.

Estimation and Modelling Techniques

Area

The lateral extent of the indicated resource is defined by the tenement boundary and the Playa edge.  Within the tenement area there are two significant features that reduce the total area, namely the island in the central north of the tenement (3.2km2) and the Williamson pit and associated dewatered zone (4km2).  The total area of the resource is 55.4 km2. The resource is open to the east and south of the Blackham Resources tenements.

Thickness

The top of the indicated resource is defined by the water table. The average water table depth beneath the playa surface noted in the piezometers and test pits ranged 0.3 to 0.5m averaging 0.4m.

The base of the indicated resource is defined by the depth to the base of the lakebed sediments within the Blackham Mining Leases as determined from the test pits, piezometers, air core drilling and previous work. Test pits to the west terminated in weathered basement at around 3mbgl whilst some air core holes to the east didn’t encounter base of the lakebed sediments until 9mbgl. All air core holes and test pits terminated in saturated material. 

The base of the lakebed sediments was interpolated from recent and historic drill hole information and the recent data using the Leapfrog software. The interpolation provided an average thickness of 5.3m.

Porosity

Total porosity (Pt) relates to the volume of brine filled pores contained within a unit volume of aquifer material. A fraction of this pore volume can by drained under gravity, this is described as the drainable porosity (or specific yield).  The remaining fraction of the brine, which is held by surface tension and cannot be drained under gravity, is described as the un-drainable porosity (or specific retention). The resource estimate is reported for both total porosity and drainable porosity to assess the Lake Way resource.

Twenty four (24) samples were selected from push tube locations next to test pit locations and from test pit excavations and LYTR01 (Trench 1) across the playa. The push tube samples were analysed by E-Precision Laboratories in Perth and the remaining samples by Core Laboratories in Perth. Samples were selected on the basis of spatial variability across the playa and being representative of the lakebed stratigraphy. Eighteen (18) of the samples were also tested for drainable porosity (Specific Yield). The samples selected, and the results are shown in Table.

The results show a broad concentration into two layers with the upper layer 0 – 1.5m having a porosity in the region of 50% and the lower layer having a porosity of around 40%.  Drainable porosity is generally lower towards the base of the lakebed sediments. This differentiation is consistent with the geology, the upper layer being more friable and sandy and the lower layers being more dense clay.

Long Term Test Pumping

Sustained pump tests on two test trenches provided reliable data for the preparation of a surface aquifer hydrogeological model for Lake Way.

The testing was conducted as a “constant head test” whereby flow rate was adjusted to maintain a constant trench water level. Drawdown was observed at nearby observation bores placed at distances of 10m, 20m and 50m from the trench.

Trench dimensions and pumping test results are presented in Table 5.

Average flow rates over the duration of testing ranged from 94 to 110m3/day. Higher flow rates are associated with evaporite deposits in the Playa Sediments.

These results are encouraging and continue to support the design of the SOP operation at Lake Way.

Table 5: Summary of Trench Test Pumping

Brine chemistry was consistent throughout the duration of the test.

Analysis of the data from trench pumping trials at test trenches LYTR01 and LYTR02 yields estimates of drainable porosity of 13% and 15% respectively. These values are consistent with literature values for clastic sediment and are consistent with estimates of playa sediment drainable porosity reported by other Salt Lake Brine evaluation studies.

Williamson Pit

The Measured Resource is calculated as the tonnage of minerals dissolved in the liquid brine contained within the Williamson Pit shell.

The potassium tonnage of the resource is then calculated as: Brine volume times average concentration = tonnage

The Williamson pit was mined during 2005 and 2006. At the end of mining a detailed survey was undertaken (2006) prior to the open cut operation being allowed to fill with water.

This data represents the most recent information available on the pit shell.

A drone survey of the pit in 2016 established that the water level was at RL1462 (Referenced to Blackham mine grid). Using this RL and the pit shell the volume was calculated in Surpac to be 1,150,495m3.

Brine Chemistry

Lake Way

All brine samples are considered to be composite samples representing the whole excavated or drilled depth at each location. Given that the proposed abstraction techniques will involve trenches excavated to at least 4m across a large portion of the playa the use of composite samples is representative of the resource that will be extracted.

Mining Factors or Assumptions

The measured resource will be pumped directly from the pit into a holding pond for processing.  Mining of the indicated resource will be undertaken by gravity drainage of the brine by pumping from trenches. 

Metallurgical Factors or Assumptions

No metallurgical factors or assumptions have been applied.

The brine is characterised by elevated concentration of potassium, magnesium and sulphate elements and distinctly low in calcium ion. Such a chemical makeup is considered highly favourable for efficient recovery of potassium double salts from the playa brines (the main feedstock for SOP fertiliser production), using conventional evaporation methods.

Environmental Factors or Assumptions

Environmental impacts are expected to be; localized reduction in saline groundwater level, surface disturbance associated with trench and pond construction and accumulation of salt tails. The project is in a remote area and these impacts are not expected to prevent project development.

The project is located with the Goldfields Groundwater Proclamation Area. A license to take groundwater will be required under the Rights in Water and Irrigation Act 1914. This act is administered by the Government of Western Australia, Department of Water and Environmental Regulation.

MINING AND SCHEDULING

Brine Extraction

Brine will be extracted from the Lake using a network of surface trenches. A trenching system comprising of 30 km of trenches up to 5m deep will be installed.

The trench system will feed the evaporation ponds at an average annual demand of 163 L/s. The trenches will be excavated at a nominal gradient, with a single transfer point into the halite pond system.

Brine Evaporation

The extracted brine is concentrated in a series of solar ponds to induce the sequential precipitation of salts and eventually producing potassium double salts in the harvest ponds. Evaporation modelling, pond sizing and design was completed by international experts, Ad Infinitum and CPPC.

Evaporation Ponds

The operational area of the evaporation ponds required for the final 50,000 t/a SOP production rate is 350ha.

A comprehensive geotechnical investigation by the Company and Knight Piesold confirmed the availability of in-situ clays ideal for on-lake evaporation pond construction.

On-lake harvest ponds have considerable environmental and commercial advantages, as any seepage from the ponds simply return to the brine pool in the Lake.

The Demonstration Plant Scoping Study considers low cost, un-lined ponds for the evaporation and crystallisation of halite (NaCl) and small quantities of other rejected salts such as gypsum (Ca.SO4.2H2O).

The kainite and carnallite harvest ponds will be partially lined, with a HDPE liner around the inside walls (berms). Knight Piésold’s modelling confirm that the high clay content and low soil permeability of the Lake Way playa sediments mean seepage of unlined evaporation ponds is very low.

Ongoing testwork will determine whether the harvest ponds can also be constructed without partial lining as indicated by preliminary modelling, which would result in further capital savings.

The pond systems will produce, on average 326Kt per annum of harvest salts, with an average Potassium (K) content of 8.76%. The Company has developed a high level of understanding of salt harvest parameters through computer simulations, laboratory evaporation trials and SLP’s unique experience in operating evaporation trials in the field at Lake Wells. The combination of this experience has been used to build and refine the mass balance model for the Demonstration Plant.

The harvest salts will be drained, windrowed and harvested using conventional equipment, a cost-effective and reliable harvesting method in Australia. 

PROCESSING PLANT

Salts harvested form the evaporation ponds are then treated in a processing plant to first purify and then convert these salts into SOP, while minimising deportment of sodium chloride (the principal contaminant) to the product.

Key design parameters for the process plant are presented in Table 8, below.

Table 8: Process Plant Parameters

Overall potassium recoveries are lower in the Demonstration Plant as potassium reporting to the carnallite ponds is not processed at this scale. Carnallite salt will be stockpiled for Stage II processing.

The scale of the process plant is designed around the largest scale of standard road transportable modules that can be constructed off-site and transported to site, minimising site based construction costs. The majority of the process plant components are readily available, off the shelf items. There are several long lead-time items, such as the atmospheric draft tube baffle crystalliser, which will be sourced from international specialist vendors.

The Scoping Study anticipates production of 50,000tpa of high quality, organic standard SOP with the following specifications:

Potassium (K2O)

Min. 52%

Sulphate (SO4)

Min. 54%

Chloride (Cl)

< 1%

SLP’s research indicates that, once in production, organic certification for the product should be obtainable if desired.

Discussions with partners and end users around the optimal product preparation for the Demonstration Plant are ongoing, including the possibility of agglomerated or and compacted of a granular products.

WATER AND POWER

A raw water requirement of around 45m3/h is estimated, of which 7m3/h is treated in a reverse osmosis unit for potable and boiler feed water. A number of potential sources have been identified, as a consequence of the long exploration and mining history in the area, including from existing mining voids and known subterranean aquifers.

The operating power requirement for the plant is 0.8MW. There is substantial surplus capacity available from the Wiluna Gold Mine power station. The Company is also investigating stand-alone renewable energy alternatives.

TRANSPORT

The lakes of the GSLP are located close to the major regional transport and energy infrastructure corridors. Transport from site to port is the single largest cost for (export oriented) Australian salt lake SOP projects and the GSLP has a considerable advantage in this regard, with excellent proximity to the Kalgoorlie-Leonora rail line and the Goldfields Highway. The Company has made substantial progress in understanding and optimising its transport proposition, with major economies of scale to be achieved as the production volume increases.

The Lake Way development has been fast-tracked due to its significant infrastructure and transport advantages.

The Company engaged Bis Consulting to undertake a transport study for production from the Demonstration Plant. Bis is a leading provider of resources logistics in Australia, offering bulk logistics and materials handling processes.

Transport cost estimates were undertaken by Bis based on market data, industry databases, industry contacts and Bis’ existing knowledge of the Western Australian infrastructure market.

The outcome of the transport study provided a number of alternatives, however for Demonstration Plant production volumes, the most efficient route to international markets was via Geraldton port.

Total transport and handling costs have been estimated at $95/t of SOP product, packed in 2 tonne bags and loaded on flat bed trailers. The main road routes for Wiluna to Geraldton are currently permitted for quad road trains. 

Geraldton Port is capable of handling fully loaded Panamax size vessels up to 70,000 tonnes and 225m in length.  The Port handles approximately 19mt per annum of trade per year with significant excess capacity available for handling and storage.

At a slightly higher cost, a bimodal solution is available based on containerised product road hauled to Leonora and then by rail to Fremantle, Esperance or elsewhere from Kalgoorlie.

MINING INFRASTRUCTURE

Lake Way was identified due to its strategic location and significant infrastructure advantages. The Wiluna region is an historic mining precinct dating back to the late 19th century. It has been a prolific nickel and gold mining region and therefore has well developed, high quality infrastructure in place.

Lake Way has some compelling advantages which makes it an ideal site for an SOP operation, including the substantial capital and operating savings from sharing overheads and infrastructure with the Wiluna Gold Mine. This includes potentially the accommodation camp, flights, power, maintenance, infrastructure and other costs. There is also a large mining camp and sealed airstrip at the nearby Mount Keith Nickel Mine.

This proximity to existing infrastructure requires relatively minor area infrastructure upgrades and modifications for the Demonstration Plant development. The site has an excellent freight solution, located 2km from Goldfields Highway, which is permitted for heavy haulage 4 trailer road trains (refer to Transport section). It is also adjacent to the Goldfields Gas Pipeline.

PRODUCT QUALITY AND MARKETING

Fertilisers consist of essential plant nutrients that are applied to farmed crops in order to achieve favourable quality and yield. They replace the nutrients that crops remove from the soil, thereby sustaining the quality of crops, and are considered the most effective means for growers to increase yields.

The key components of agricultural fertilisers are nitrogen (ammonia and urea), phosphates (ammonium phosphates), and potassium (muriate of potash and sulphate of potash). In addition, sulphate has gained increased attention over the past several years due to soils becoming deficient in sulphur (the ‘fourth macronutrient’).

Global fertiliser demand is expected to increase significantly in the coming years due to the world population growth accompanied by decreasing arable land per capita, changes in diet and growth in income. These increases will provide an incentive for farmers to increase fertiliser use for improved yields and quality.

The most widely available source of potassium used by growers is Muriate of Potash (MOP or KCl), with around 65 million tonnes consumed annually. SOP is a speciality type of potassium fertilisers that is produced and consumed on a smaller scale.

MOP is widely used in all types of farming, however it can be detrimental to some plants, especially fruits and vegetables, due to its chloride content. SOP is primarily used as a source of potassium for crops intolerant to chloride. SOP is priced at a premium to MOP, due to supply constraints, high production costs and because of its ability to be used on chloride intolerant crops (such as fruits, vegetables, beans, nuts, potatoes, tea, tobacco and turf grass), which typically sell at sufficiently higher prices to absorb the premium cost.

SOP can be used in most applications where MOP is used and is preferred in many circumstances as it enhances yield and quality, shelf life and improves taste. SOP generally outperforms MOP in terms of crop quality and yield. SOP performs particularly well with crops that have a low tolerance to the chloride in MOP and in arid, saline and heavily cultivated soils. The low volume of SOP consumption relative to market demand is partly a result of the scarcity of reliable SOP supply.

SOP’s premium to the MOP price is correlated to the conversion costs from MOP to SOP (Mannheim Process) where MOP is used as an input in the process. The premium has been around 60% for the past decade. In recent years, this premium has expanded significantly, as decreases in the MOP price have not translated to similar declines in the price of SOP, indicating that the SOP market is supply constrained.

SOP can be sold as a standard powder or as a premium granular or soluble grade product. Granular and coarse SOP is generally priced at a premium. Salt Lake Potash plans to sell at a premium to the market price as a certified organic producer, similar to Compass Minerals.  The primary production of SOP from salt lakes allows for organic certification.

The current spot price for SOP ranges from US$580-US$635 per tonne in the main North American markets, with different (and less visible) prices in other global markets.

The Company’s Fertiliser marketing consultant, Fertiliser Sales Development (FSD) has over 25 years experience in the sales, marketing and distribution of various fertiliser products. FSD expects the long-term price for SOP FOB ex-Western Australia to be at least US$500/t for standard grade.

The Company’s main initial target market is the Asia-Pacific and East-Asia, a region forecasting significant increases in the demand for SOP. SOP production is not easily substitutable and is in supply deficit, therefore the Company is confident in the current and forecasted levels of demand.

Off-take

In April 2018, SLP executed a Memorandum of Understanding (MOU) with Mitsubishi Australia Limited and Mitsubishi Corporation (Mitsubishi). The Offtake Agreement will provide Mitsubishi with sales and offtake rights for up to 50% of the SOP production from the Demonstration Plant, for distribution into Asia and Oceania and potentially other markets. 

Discussions are ongoing with various parties for the balance of the Demonstration Plant production.

ENVIRONMENTAL & SOCIAL IMPACT ASSESSMENT

SLP’s consultants Pendragon Environmental under took a gap analysis to identify gaps in historical environmental knowledge, potential issues arising from the approval process, identify statutory approval requirements for the Demonstration Plant and provide a time frame for the environmental approvals.

As the proposed activities are to take place on active mining leases SLP has access to previous completed detailed environmental reports. The key findings for areas that required additional work:

·        Native Terrestrial Flora and Fauna – Ground truthing of specific infrastructure prior to submission of mining proposal.

·        Ground water – water balance and water quality requirements for plant operations.

·        Surface water – drainage study to be incorporated in to final location of trenches and pond layout.

·        Heritage – No registered Aboriginal sites were found within the impact area. Continuing engagement with the Aboriginal Community is required.

PERMITTING AND FISCAL REGIME

The Demonstration Plant will initially be based on Mining Leases held by Blackham Resources Limited, under the Memorandum of Understanding (MOU) described in the ASX Announcement dated 12 March 2018.

For supporting infrastructure or areas not included under Blackham’s ground, the Company will obtain Miscellaneous Licences.

The Company has agreed to extend the MOU timeline with Blackham Resources Ltd to 31 August 2018 as drafting of formal Spilt Commodity Agreement progresses.

The Company is also in ongoing discussions with the Native Title holders at Wiluna regarding an Exploration Agreement covering SLP’s exploration permits. We continue to work toward a mutually beneficial relationship with the Wiluna community.

Royalties

Potash has not been produced in Western Australia since 1950. The current royalty legislation does not include any specific rate for potash produced in WA. The ad valorem or value-based rate of royalty, which applies under the Mining Regulations 1981, is applied to a commodity based on the extent to which the commodity has been processed. As the SOP is sold in its final form (not subject to any further refinement or processing before sale to consumers) a royalty rate of 2.5% is expected. 

Other royalties provided for in the Scoping Study estimates include to the holder of Blackham tenements.

PROJECT TIMING

The Company will pursue a staged approach to development of a Demonstration Plant at Lake Way, taking advantage of the unique circumstances of the Williamson Pit to accelerate the production timeline, while also de-risking the project at each stage.

Completion of the Scoping Study provides the basis to now proceed with a Feasibility Study, to be completed in late 2018 or early 2019.

In parallel, SLP and Blackham have applied for a permit to construct the Williamson Ponds, to allow dewatering of the Williamson Pit in time to meet Blackham’s mine plan. Both companies aim to complete the construction and dewatering by late 2018/early 2019, subject to permitting, weather and other constraints.

The Williamson Ponds comprise approximately one third of the total Demonstration Plant pond area and will provide the opportunity to resolve design and construction processes and costs to a very high standard for the Feasibility Study. In order to manage the chemistry of the Williamson brines, ancillary brine trenches will also be required, which will similarly provide a high standard of hydrogeological and construction data.

Williamson brines are the highest grade brine resource in Australia, containing approximately 25kg/m3 of SOP. They are also super-saturated with other salts, boasting an average Total Dissolved Salt content of approximately 30%. This means that the brines will precipitate halite and gypsum salts almost immediately they are pumped from the Pit.

This offers the opportunity to use the Williamson brines to lay down a salt base in the harvest ponds much more quickly than would normally be the case for less concentrated brines. A salt base is an important element of evaporation pond construction, providing a platform or pavement for harvest equipment, and can take many months to develop depending on requirements, brine chemistry and weather.

The very high grade of the Williamson brines also reduces the evaporation time required for precipitation of kainite harvest salts.

Construction of the Williamson ponds, dewatering of the Williamson Pit and the initial evaporation and salt precipitation, will provide a very high level of information and understanding of the parameters for brine extraction and evaporation in an Australian context, at a scale directly representative of the complete operation.  For a very modest capital expenditure, this information will substantially reduce the perceived risk, and improve the financing parameters, for the balance of the project.

[Note that the capital expenditure estimated in the Scoping Study for the full Demonstration Plant evaporation pond system totals $7.8m, and the Williamson Ponds are one third of that area.]

Subject to permitting, performance, weather and other factors, the construction of the balance of the on-lake infrastructure – mainly the remaining ponds and brine trenches – will ideally follow on directly from completion of the Williamson Ponds and the Feasibility Study.

The Study estimates the extraction trench network capital expenditure is a further $1.6m, meaning the total capital expenditure for on-lake infrastructure is $9.4m, slightly less than 20% of the total capex.  If the construction and operation of the Williamson Ponds validates the modelled performance of unlined harvest ponds, then the potential savings from not using partial HDPE liners, will significantly reduce capex for the balance of the pond system.

The longest lead time for the main plant components is 36 weeks, for the crystalliser, which will be fabricated off-shore. The Scoping Study estimates total fabrication and installation time for the process plant at approximately 9-12 months, meaning a decision taken at the anticipated time of completion of the Feasibility Study would result in plant commissioning in early 2020, utilising stockpiled kainite harvest salts.

The Company will continue to investigate opportunities to reduce the development schedule by early ordering of long-lead time items and modular delivery and installation of plant components, an option available for a small scale, skid mounted plant.

The Company’s anticipated delivery schedule is naturally provisional at this stage, subject to permitting, performance, financing, weather and other factors.

Table 8: Sensitivity Analysis 

SUMMARY OF MODIFYING FACTORS

The Modifying Factors included in the JORC Code have been assessed as part of the Scoping Study, including mining (brine extraction), processing, metallurgical, infrastructure, economic, marketing, legal, environmental, social and government factors. The Company has received advice from appropriate experts when assessing each Modifying Factor.

A summary assessment of each relevant Modifying Factor is provided below.

Mining (Brine Extraction) – refer to section entitled ‘Mining and Scheduling’ in the Announcement.

The Company engaged an independent hydrogeological consultant with substantial salt lake brine expertise, Groundwater Science Pty Ltd, to complete the Mineral Resource Estimate for the Lake Way project. The Principal Hydrogeologist of Groundwater Science, Mr Jeuken, has over 10 years of experience in groundwater resources assessment and management for mining. He has experience in salt lake brine potash evaluation, aquifer testing, wellfield planning and installation for mining, and the development of conceptual hydrogeological models

The hydrological model was produced by the Company in consultation with independent experts. The two methods of extraction outlined in the Announcement are common practice for brine extraction. These extraction methods are used by the three main current operations which include Great Salt Lake in the US, Lop Nur Salt Lake (Luobupo) and SQM in Chile. 

Processing (including Metallurgical) – refer to sections entitled ‘Mining and Scheduling’ and ‘Processing Plant’ in the Announcement.

The Company engaged brine-processing experts Carlos Perucca Processing Consulting Ltd (CPPC) and AD Infinitum Ltd (AD Infinitum) and their principals Mr Perucca and Mr Bravo, who are highly regarded international experts in the potash industry. Mr Bravo previously worked as Process Manager Engineer at SQM, the third largest salt lake SOP producer globally. He specialises in the front end of brine processing from feed brine through to the crystallisation of harvest salts. Mr Perucca has over 25 years of experience in mineral process engineering and will provide high-level expertise with respect to plant operations for the processing of harvest salts through to final SOP product. AD Infinitum and CPPC were responsible for the brine evaporation and salt processing components in the Scoping Study.

Lake Way’s process development relied heavily on experience applied by Wood and specialist consultants (CPPC and Ad Infinitum) who are well experienced from working on similar operations. Production of SOP from lake brines is well understood and a well-established process.

Infrastructure – refer to section entitled ‘Mining Infrastructure’ in the Announcement.

Lake Way’s proximity to the West Australian goldfields means relatively minor area infrastructure upgrades and modifications are required.

The Scoping Study was managed by Wood. Wood is a recognised global leader in potash mining and processing with capabilities extending to detailed engineering, procurement and construction management. Wood are able to leverage an international network, including access to its Centre of Potash Excellence located in Saskatoon, Canada. All capital and operating costs were estimated by Wood.

Transport cost estimates were undertaken by Bis Consulting based on market data, industry databases, industry contacts and Bis’ existing knowledge of the Western Australian infrastructure market.

Marketing – refer to section entitled ‘Product Quality and Marketing’ in the Announcement.

Independent potash market forecasts and assessments were provided by experts FSD, Greenmarkets, CRU International.

FSD’s scoping level assessment of local and regional markets indicates that various markets around the world and particularly in the Asia-Pacific region would absorb the planned production output of the Demonstration Plant either to fill new demand or to substitute lower quality or higher cost supply.

Salt Lake has undertaken initial market discussions with local and international fertiliser industry participants, which have indicated substantive interest in a new and stable supplier of high quality organic SOP from an Australian salt lake project.

The execution of an initial non-binding MoU with Mitsubishi confirmed there is a reasonable expectation the Company will be able to execute off-take agreements with customers.

The current spot price for SOP is around US$625 (FOB Northwest America).

The Company’s target market is the Asia-Pacific, a region forecasting significant increases in the demand for SOP. SOP production is not easily substitutable and is in supply deficit, therefore the Company is confident in the current and forecasted levels of demand.

Salt Lake will continue to focus on developing marketing relationships and discussions with potential additional off-take and trade partners.

Economic – refer to sections entitled ‘Product Quality and Marketing’ in the Announcement.

A detailed financial model and discounted cash flow (DCF) analysis has been prepared in order to demonstrate the economic viability of the Project. The financial model and DCF were modelled with conservative inputs to provide management with a baseline valuation of the Project. Sensitivity analysis was performed on all key assumptions used. Key inputs and assumptions are outlined in Table 1 to allow analysts and investors to calculate Project valuations based on their own revenue assumptions.

The Company engaged the services of a funding and debt advisory firm, Argonaut. Argonaut is a financial advisory and investment banking firm which specialises in the metals, oil & gas and agri-business sectors. Argonaut is well regarded as a specialist capital markets service provider and have raised project development funding (including debt, equity, hybrid instruments and strategic capital/partners) for companies across a range of commodities including substantial experience in the industrial and speciality minerals sector. Following the assessment of a number of key criteria, Argonaut has confirmed in writing that, provided a definitive feasibility study arrives at a result not materially worse than the Scoping Study, the Company should be able to raise sufficient funding to develop the Project.

An assessment of various funding alternatives available to Salt Lake has been made based on precedent transactions that have occurred in the mining industry, including an assessment of alternatives available to companies that operate in industrial and specialty minerals sector. The assessment and advice from Argonaut (referred to above) indicates that financing for industrial mineral companies often involves a broader mix of funding sources than just traditional debt and equity, and the potential funding alternatives available to the Company including, but not limited to: royalty financing; mezzanine finance; prepaid off-take agreements; equity; joint venture participates; strategic partners/investors at project or company; senior secured debt/project finance; secondary secured debt; and equipment leasing. It is important to note that no funding arrangements have yet been put in place, as these discussions will usually commence upon completion of a Feasibility Study with results not worse than this Scoping Study. The composition of the funding arrangements ultimately put in place may also vary, so it is not possible at this stage to provide any further information about the composition of potential funding arrangement.

Since the acquisition of the Project in June 2015, the Company has completed comprehensive exploration programs across the GSLP, with the delineation of Mineral Resources at both Lake Wells and Lake Way, and the successful completion of positive Scoping Studies on Lake Wells and now for the Demonstration Plant for Lake Way. Over the last six months, the Company’s market capitalisation has ranged between A$75m and A$110m.

Salt Lake has a high quality Board and management team comprising highly respected resource executives with extensive finance, commercial and capital markets experience. The Company’s Chairman has previously raised over A$1 billion from capital markets for a number of exploration and development companies.

As a result, the Board has a high level of confidence that the Project will be able to secure funding in due course, having particular regard to:

–    Required capital expenditure;

–    Salt Lake Potash’s market capitalisation;

–    Recent funding activities by Directors in respect of other resource projects;

–    Recently completed funding agreements for similar or larger scale development projects;

–    The range of potential funding options available;

–    The favourable key metrics generated by the Project and GSLP; and

–    Investor interest.

Environmental – refer to section entitled ‘Environmental & Social Impact Assessment’ in the Announcement.

An opportunities and constraints assessment was completed for the Project by Pendragon Environmental, a leading Western Australian environmental management consultancy. Based on the Project’s stage of development, Pendragon Environmental confirmed there are no current impediments on the Project.

To date, SO4 has only undertaken preliminary desktop studies for the purposes of identifying potential environmental opportunities and constraints. Extensive data is available across the Scoping Project area from work undertaken historically by Blackham Resources. The further development of the Project may require additional detailed flora, fauna and other studies; this is dependent on the final design criteria.  

Social, Legal and Governmental – refer to section entitled ‘Permitting and Fiscal Regime’ in the Announcement.

The Company has taken legal advice in relation to relevant Modifying Factors.

Based on the legal advice received the Company considers there is presently no reason to believe that the development of the Demonstration Plant is not able to be developed, constructed and operated on Blackham Resources Limited’s current Mining Leases, subject to obtaining necessary regulatory approvals.

APPENDIX 2 – JORC TABLE ONE

Section 1: Sampling Techniques and Data

Criteria

JORC Code explanation

Commentary

Sampling techniques

Nature and quality of sampling (eg cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc). These examples should not be taken as limiting the broad meaning of sampling.

Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used.

Aspects of the determination of mineralisation that are Material to the Public Report.

In cases where ‘industry standard’ work has been done this would be relatively simple (eg ‘reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay’). In other cases more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (eg submarine nodules) may warrant disclosure of detailed information.

Lake Way

Sampling involved the excavation of 36 test pits over the tenement area to a depth of 4mbgl or weathered basement whichever was encountered first.  Two trenches were also dug to 4m depth, Trench 1 112m long in a north south orientation and Trench 2 100m long in an east west orientation.

 

A brine sample and duplicate were taken from each test pit and trench for analysis.

 

Samples were taken manually by initially rinsing out the bottle with brine from the pit or trench and then placing the bottle in the test pit or trench and allowing it to fill.

Samples were analysed for K, Mg, Ca, Na, Cl, SO4, HCO3, NO3, pH, TDS and specific gravity.

 

Each test pit was geologically logged and a sample taken each 1m depth.

 

Williamson Pit

Samples were taken manually at three locations along the pit lake and at three depths at each location giving a total of 9 sampling locations in total.

At each location a brine sample and duplicate were taken for analysis.

Samples were analysed for K, Mg, Ca, Na, Cl, HCO3, SO4 and NO3

 

Drilling techniques

Drill type (eg core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (eg core diameter, triple or standard tube, depth of diamond tails, face-sampling bit or other type, whether core is oriented and if so, by what method, etc).

Lake Way

No drilling was undertaken. 

 

Test pits were dug with an excavator approximately 2m long x 1m wide x 4m deep.

Drill sample recovery

Method of recording and assessing core and chip sample recoveries and results assessed.

Measures taken to maximise sample recovery and ensure representative nature of the samples. Whether a relationship exists between sample recovery and grade and whether sample bias may have occurred due to preferential loss/gain of fine/coarse material.

Lake Way

Samples from the test pits were logged each bucket and a representative sample bagged.

 

100% of excavated sample was available for sampling.  The ability to see the bulk sample facilitated the selection of a representative sample.

Lake Way

The geological logging is sufficient for the purposes of identifying variations in sand/ clay and silt fraction within the top 4m.  For a brine abstraction project, the key parameters are the hydraulic conductivity and storativity of the host rock, which will be determined during test pumping of the trenches.

The logging is qualitative.

The entire pit depth was logged in every case.

Not applicable

At all test pits brine samples were taken from the pit after 24hours or once the pit had filled with brine.  The brine samples taken from the pits are bulk samples which is an appropriate approach given the long-term abstraction technique of using many kilometres of trenches to abstract brine from the upper 4m.

All the samples taken were incorporated into a rigorous QA / QC program in which Standards and Duplicates were taken. The samples were taken in sterile plastic bottles of 250ml capacity.

Excavated lake bed samples were sealed in plastic bags.  For all brine samples (original or check samples) the samples were labelled with the alphanumeric code Y8001, Y80002 …

Not applicable, no adjustments were made to the data

Location of data points

Accuracy and quality of surveys used to locate drill holes (collar and down-hole surveys), trenches, mine workings and other locations used in Mineral Resource estimation.

Specification of the grid system used.

Quality and adequacy of topographic control.

Lake Way

All coordinates were collected by handheld GPS.

The grid system is the Australian National Grid Zone MGA 51 (GDA 94)

There is no specific topographic control as the lake surface can essentially be considered flat.

 

Williamson Pit

The pit lake sampling locations were located with a GPS.  Whilst the samples were taken from a boat in the lake, movement was limited as far as possible.

The depth from the pit lake surface to the ground surface was measured from calibrated drone survey footage

When the samples were being taken the depth to the base of the pit was also measured and recorded at each of the three sampling locations.

All coordinates were collected by handheld GPS.

The grid system is the Australian National Grid Zone MGA 51 (GDA 94)

The is no specific topographic control as the pit lake surface can essentially be considered flat.

 

 

Data spacing and distribution

Data spacing for reporting of Exploration Results.

Whether the data spacing and distribution is sufficient to establish the degree of geological and grade continuity appropriate for the Mineral Resource and Ore Reserve estimation procedure(s) and classifications applied.

Whether sample compositing has been applied.

Lake Way

The lake area contained within the Blackham tenement was calculated by digitising the lake surface and removing the area covered by the islands and the dewatered area of the Williamson pit, the approximate area is 55.4km2.  36 test pits and 2 trenches were excavated over the BRT surface resulting in 1 excavation per 1.5Km2. Which is a high density of investigation for a salt-lake and sufficient to establish variations in depth to basement, sedimentology and local hydraulic conductivity.

 

Sample compositing not applicable

 

Williamson Pit

The Williamson pit is orientated north south and is approximately 600m long, 100m wide with a calculated brine volume of 1,150,495m3.  Nine samples were taken giving a sample density of 1 per 128,000/m3 given the limited size of the pit and no observed inflows the sample density was deemed appropriate for this resource.

 

Orientation of data in relation to geological structure

Whether the orientation of sampling achieves unbiased sampling of possible structures and the extent to which this is known, considering the deposit type.

If the relationship between the drilling orientation and the orientation of key mineralised structures is considered to have introduced a sampling bias, this should be assessed and reported if material.

Lake Way

There are no structural or geological controls with respect to sampling the lake bed sediments.  The variation in depth to basement does control the potential depth of future trench systems to the west of Williamson pit and the main island.

 

Geological influence on the brine is limited to the aquifer parameters of the host rock, namely the hydraulic conductivity, drainable porosity and storativity.

 

Williamson Pit

 

Not Applicable.

Criteria

JORC Code explanation

Commentary

Mineral tenement and land tenure status

Type, reference name/number, location and ownership including agreements or material issues with third parties such as joint ventures, partnerships, overriding royalties, native title interests, historical sites, wilderness or national park and environmental settings.

The security of the tenure held at the time of reporting along with any known impediments to obtaining a licence to operate in the area.

 

On the 9th March 2018 Salt Lake Potash Ltd. and Blackham Resources Ltd. signed a gold and brine minerals memorandum of understanding.  Under this MOU Blackham has granted the brine rights on its Lake Way tenement free from encumbrances to SLP.

The tenements referred to in the MOU are; Exploration licences E53/1288, E53/1862, E53/1905, E53/1952, Mining Licences, M53/121, M53/122, M53/123, M53/147, M53/253, M53/796, M53/797, M53/798, M53/910, and Prospecting Licences P53/1642, P53/1646, P53/1666, P53/1667, P53/1668.

 

All tenure is granted to Blackham Resources Ltd.

Exploration done by other parties

Acknowledgment and appraisal of exploration by other parties.

There is a database of approximately 6200 boreholes across Lake Way of which some 1000 are within the Blackham tenement.  The primary source for the information is the publicly available Western Australian Mineral Exploration (WAMEX) report data base.

Recent sterilisation drilling has also been undertaken by Blackham resources to the south and east of the BRT area.

The majority of previous work has been concerned with investigating the bedrock and calcrete for gold and Uranium, it is of limited value in defining the stratigraphy of the lakebed sediments.  The data has been shown to be useful in the determination of the depth to base of lakebed sediments and has been used to develop an overall estimate of the volume of lake bed sediments that has been applied to the mineral resource calculations.

 

Geology

Deposit type, geological setting and style of mineralisation.

The deposit is a salt-lake brine deposit.

The lake setting is typical of a Western Australian palaeovalley environment. Ancient hydrological systems have incised palaeovalleys into Archaean basement rocks, which were then infilled by Tertiary-aged sediments typically comprising a coarse-grained fluvial basal sand overlaid by palaeovalley clay with some coarser grained interbeds. The clay is overlaid by recent Cainozoic material including lacustrine sediment, calcrete, evaporite and aeolian deposits. 

Drill hole Information

A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drill holes:

o   easting and northing of the drill hole collar

o   elevation or RL (Reduced Level – elevation above sea level in metres) of the drill hole collar

o   dip and azimuth of the hole

o   down hole length and interception depth

o   hole length.

If the exclusion of this information is justified on the basis that the information is not Material and this exclusion does not detract from the understanding of the report, the Competent Person should clearly explain why this is the case.

No drilling was undertaken. 

36 test pits and 2 trenches were excavated on the lake surface.

All test pit and trench details and locations of all data points are presented in the report.

 

Data aggregation methods

In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (eg cutting of high grades) and cut-off grades are usually Material and should be stated.

Where aggregate intercepts incorporate short lengths of high grade results and longer lengths of low grade results, the procedure used for such aggregation should be stated and some typical examples of such aggregations should be shown in detail.

The assumptions used for any reporting of metal equivalent values should be clearly stated.

Within the salt-lake extent no low-grade cut-off or high-grade capping has been implemented due to the consistent nature of the brine assay data.

Test pit and trench data aggregation comprised calculation of a hydraulic conductivity for the whole sequence using the Hvorslev (1951) recovery analysis technique.

 

Relationship between mineralisation widths and intercept lengths

These relationships are particularly important in the reporting of Exploration Results.

If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported.

If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (eg ‘down hole length, true width not known’).

The chemical analysis from each of the test pits has shown the that the brine resource is consistent and continuous through the full thickness of the Lake Playa sediments unit. The unit is flat lying all test pits were excavated into the lake sediments to a depth of 4m or basement, the intersected depth is equivalent to the vertical depth and the thickness of mineralisation.

 

 

Diagrams

Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any significant discovery being reported These should include, but not be limited to a plan view of drill hole collar locations and appropriate sectional views.

Addressed in the announcement.

Balanced reporting

Where comprehensive reporting of all Exploration Results is not practicable, representative reporting of both low and high grades and/or widths should be practiced to avoid misleading reporting of Exploration Results.

All results have been included.

Other substantive exploration data

Other exploration data, if meaningful and material, should be reported including (but not limited to): geological observations; geophysical survey results; geochemical survey results; bulk samples – size and method of treatment; metallurgical test results; bulk density, groundwater, geotechnical and rock characteristics; potential deleterious or contaminating substances.

All material exploration data has been reported.

Further work

The nature and scale of planned further work (eg tests for lateral extensions or depth extensions or large-scale step-out drilling).

Diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, provided this information is not commercially sensitive.

Further trench testing and numerical hydrogeological modelling to be completed that incorporates the results of the test pumping.  The model will be the basis of the annual brine abstraction rate and mine life.

Criteria

JORC Code explanation

Commentary

Database integrity

Measures taken to ensure that data has not been corrupted by, for example, transcription or keying errors, between its initial collection and its use for Mineral Resource estimation purposes.

 

Data validation procedures used.

 

Cross-check of laboratory assay reports and database.

 

Extensive QA/QC as described in Section 3 Sampling Techniques and Data

Site visits

Comment on any site visits undertaken by the Competent Person and the outcome of those visits.

 

If no site visits have been undertaken indicate why this is the cases.

 

A site visit was undertaken by the Competent Person (CP) from 29th to 30th April 2018. The CP visit was documented in Letter Report SLP-18-1-L001 (Groundwater Science, 2018).

 

Geological interpretation

Confidence in (or conversely, the uncertainty of) the geological interpretation of the mineral deposit.

 

Nature of the data used and of any assumptions made.

 

The effect, if any, of alternative interpretations on Mineral Resource estimation.

 

The use of geology in guiding and controlling Mineral Resource estimation.

 

The factors affecting continuity both of grade and geology.

 

The shallow geological profile beneath the lake is relatively homogenous.  The porosity of the material is consistent with depth; hence the geological interpretation has little impact on the resource except to define its thickness.

 

The island is excluded from the resource estimate as access is not permitted.  Mining the Williamson Pit has resulted in an area of approximately 4km2 being dewatered, this areas has also been excluded from the resource estimate.

 

Dimensions

The extent and variability of the Mineral Resource expressed as length (along strike or otherwise), plan width, and depth below surface to the upper and lower limits of the Mineral Resource.

The resource extends beneath 55.4km2 of the Blackham Resources Tenements on Lake Way. The top of the resource is defined by the water table surface; on average 0.3m below ground surface.  The average thickness of the resource is 5.3m as determined from the leapfrog model.

 

The Williamson Pit volume has been estimated as 1.26million m3.

Estimation and modelling techniques

The nature and appropriateness of the estimation technique(s) applied and key assumptions, including treatment of extreme grade values, domaining, interpolation parameters and maximum distance of extrapolation from data points. If a computer assisted estimation method was chosen include a description of computer software and parameters used.

 

The availability of check estimates, previous estimates and/or mine production records and whether the Mineral Resource estimate takes appropriate account of such data.

 

The assumptions made regarding recovery of by-products.

 

Estimation of deleterious elements or other non-grade variables of economic significance (eg sulphur for acid mine drainage characterisation).

 

In the case of block model interpolation, the block size in relation to the average sample spacing and the search employed.

 

Any assumptions behind modelling of selective mining units.

 

Any assumptions about correlation between variables.

 

Description of how the geological interpretation was used to control the resource estimates.

 

Discussion of basis for using or not using grade cutting or capping.

 

The process of validation, the checking process used, the comparison of model data to drill hole data, and use of reconciliation data if available.

 

Brine concentration was interpolated using both Ordinary kriging and Voronoi polygons

 

The thickness of the lakebed sediments was developed using the Leapfrog software package and an inverse distance weighted calculation applied to the WAMEX boreholes database covering Lake Way.

Average test pit spacing was 500m.

No check estimates were available

No recovery of by-products was considered

Deleterious elements were not considered

Selective mining units were not modelled.

Correlation between variables was not assumed.

The geological interpretation from the WAMEX database was used to inform the Leapfrog model which was used to define the thickness of the orebody.

Grade cutting or capping was not employed due to the homogenous nature of the orebody. 

 

Moisture

Whether the tonnages are estimated on a dry basis or with natural moisture, and the method of determination of the moisture content.

Not applicable to brine resources. See discussion of moisture content under Bulk Density

Cut-off parameters

The basis of the adopted cut-off grade(s) or quality parameters applied.

No cut-off parameters were used

Mining factors or assumptions

Assumptions made regarding possible mining methods, minimum mining dimensions and internal (or, if applicable, external) mining dilution. It is always necessary as part of the process of determining reasonable prospects for eventual economic extraction to consider potential mining methods, but the assumptions made regarding mining methods and parameters when estimating Mineral Resources may not always be rigorous. Where this is the case, this should be reported with an explanation of the basis of the mining assumptions made.

Mining will be undertaken by gravity drainage of brine from trenches.

Test pumping of two trenches was undertaken to obtain preliminary aquifer characteristics.

Metallurgical factors or assumptions

The basis for assumptions or predictions regarding metallurgical amenability. It is always necessary as part of the process of determining reasonable prospects for eventual economic extraction to consider potential metallurgical methods, but the assumptions regarding metallurgical treatment processes and parameters made when reporting Mineral Resources may not always be rigorous. Where this is the case, this should be reported with an explanation of the basis of the metallurgical assumptions made.

The brine is characterised by elevated concentration of potassium, magnesium and sulphate elements and distinctly deficient in calcium ions. Such a chemical makeup is considered highly favorable for efficient recovery of Schoenite from the lake brines (the main feedstock for Sulphate of Potash production), using conventional evaporation methods

Environmen-tal factors or assumptions

Assumptions made regarding possible waste and process residue disposal options. It is always necessary as part of the process of determining reasonable prospects for eventual economic extraction to consider the potential environmental impacts of the mining and processing operation. While at this stage the determination of potential environmental impacts, particularly for a greenfields project, may not always be well advanced, the status of early consideration of these potential environmental impacts should be reported. Where these aspects have not been considered this should be reported with an explanation of the environmental assumptions made.

Environmental impacts are expected to be; localized reduction in saline groundwater level, surface disturbance associated with trench and pond construction and accumulation of salt tails. The project is in a remote area and these impacts are not expected to prevent project development.

Bulk density

Whether assumed or determined. If assumed, the basis for the assumptions. If determined, the method used, whether wet or dry, the frequency of the measurements, the nature, size and representativeness of the samples.

The bulk density for bulk material must have been measured by methods that adequately account for void spaces (vugs, porosity, etc), moisture and differences between rock and alteration zones within the deposit.

Discuss assumptions for bulk density estimates used in the evaluation process of the different materials.

Bulk density is not relevant to brine resource estimation.

Volumetric moisture content or volumetric porosity was measured based on determination of 19 samples (average sample spacing 1.5m) to yield an average value of 43% v/v.

Classification

The basis for the classification of the Mineral Resources into varying confidence categories.

Whether appropriate account has been taken of all relevant factors (ie relative confidence in tonnage/grade estimations, reliability of input data, confidence in continuity of geology and metal values, quality, quantity and distribution of the data).

Whether the result appropriately reflects the Competent Person’s view of the deposit.

The data is considered sufficient to assign a measured resource classification to brine within the Williamson Pit shell.

The data is considered sufficient to assign an indicated resource classification to brine within the lakebed sediments within the Blackham Resources tenements excluding the Williamson Pit dewatered area and the area of the island.

The result reflects the view of the Competent Person

Audits or reviews

The results of any audits or reviews of Mineral Resource estimates.

No audit or reviews were undertaken.

Discussion of relative accuracy/ confidence

Where appropriate a statement of the relative accuracy and confidence level in the Mineral Resource estimate using an approach or procedure deemed appropriate by the Competent Person. For example, the application of statistical or geostatistical procedures to quantify the relative accuracy of the resource within stated confidence limits, or, if such an approach is not deemed appropriate, a qualitative discussion of the factors that could affect the relative accuracy and confidence of the estimate.

The statement should specify whether it relates to global or local estimates, and, if local, state the relevant tonnages, which should be relevant to technical and economic evaluation. Documentation should include assumptions made and the procedures used.

These statements of relative accuracy and confidence of the estimate should be compared with production data, where available.

It is expected that all the Williamson Pit brine will be extracted.

For the lakebed sediments the estimated tonnage represents the in-situ brine with no recovery factor applied. It will not be possible to extract all of the contained brine by pumping from trenches. The amount which can be extracted depends on many factors including the permeability of the sediments, the drainable porosity, and the recharge dynamics of the aquifers.

No production data are available for comparison
