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.
