ECR Minerals #ECR Argentina Progress Update

ARGENTINA PROGRESS UPDATE

ECR Minerals plc (LON:ECR) the precious metals exploration and development company is pleased to provide an update to shareholders following the visit by the Company to Argentina to discuss the status and plans in respect of the Company’s existing interests and also to consider potential new opportunities in Argentina that may complement existing interests.

The Company previously outlined the latest position in respect of Argentinian operations in its full year report released 29 March 2018. Then, despite having established a next stage exploration programme for the Sierra de las Minas (“SLM”) gold prospective licences, reflecting the need to conserve cash resources and to consider various corporate developments in the area of the Company’s operations, the Company decided to watch developments and conserve resources for a period.

During the visit to Argentina a full review of the SLM project licences was undertaken, including relevant liaison with the Ministry of Mining in La Rioja province. We are pleased with the outcome of this review and the opportunities we have identified for exploration of potentially high-grade gold mineralisation. With the Company’s enhanced financial strength we have now restarted our work and further information will follow with regard to the specific work programme we intend to implement.

Of particular interest during the Company’s visit we have identified additional licence areas that could complement the existing gold prospective ground and we will provide further updates in due course if there are any developments in this area.

Furthermore during a review of additional, non-gold focused projects, the Company has identified a number of completely new opportunities including a lithium and poly-metallic high impact exploration opportunity. Again, if these progress then we will provide further updates.

Craig Brown, Chief Executive Officer of ECR Minerals plc, commented: “Following the Company’s recent fundraise the business, as previously highlighted, is in a robust financial position. With our significant cash at bank and with core costs covered into late 2019 we have been able to look with fresh eyes at all the Company’s interests in order to advance existing projects and also seek new additional complementary opportunities.

Our main driving force of late has been Australian exploration and that will continue with the Board currently in Perth to review progress in our existing Victoria interests, to undertake due diligence in respect of the recently announced Iceberg gold project and to review a number of new and potential opportunities.

ECR has a long history of working in South America and particularly Argentina. We visited Argentina last week and held various meetings and discussions. Our engagement with the Department of Mining was particularly productive and we were highly encouraged by their professionalism and support for our investment in La Rioja province. In addition during our visit we were extremely pleased with the opportunities presented to expand our existing interests in gold and also lithium.

The Board have decided to become more proactive in Argentina and are now pursuing a number of initiatives upon which we will report to market if they were to progress. We look forward to updating shareholders on our progress in due course”.

Cadence Minerals #KDNC CEO Kiran Morzaria discusses the San Luis exploration programme on Vox Markets podcast

Kiran Morzaria CEO of Cadence Minerals #KDNC discusses the commencement of an exploration programme at the San Luis Lithium asset in Argentina. The interview starts at 17 minutes 27 seconds in.

Cadence Minerals #KDNC – Exploration programme on Argentina Lithium Assets commences

Cadence Minerals (AIM/NEX: KDNC; OTC: KDNCY) announced on 11 December 2017 that it had entered into binding agreements to acquire up to 100% of six high-quality lithium assets in Argentina. The Company is now delighted to inform shareholders that the initial exploration programme on these assets in the San Luis Province has started.

HIGHLIGHTS

  • Detailed desktop and remote exploration started over 55,773 hectares within the known spodumene bearing pegmatite fields in San Luis Province, Central Argentina.
  • Work includes high-resolution satellite imagery interpretation to map pegmatites or other potential lithium bearing host rock.
  • The pegmatite fields of San Luis have an important past record of producing mica, beryl, spodumene, tantalite (tantalum oxide), columbite (niobium oxide), and recently potassium feldspar, albite and quartz.
  • Based on results we will develop a ranked target list of prospective pegmatites for further exploration, sampling and drilling.
  • Cadence has completed Stage 1 of the 5-stage timetable to acquire up to 100% of the assets.

The Initial exploration programme which is targeted to complete in approximately 4-6 months, has been designed to provide the Company with a thorough understanding of the pegmatite geology and extent of lithium mineralisation.

The first part of this programme consists of detailed desktop work that is undertaken remotely, which is followed up by field work to reconcile the findings and identify key pegmatite targets. At the conclusion of this process and upon regulatory approval, the exploration program will move into sampling these targets and, if successful, exploratory drilling and the definition of mineral resources.

Kiran Morzaria, Chief Executive Officer, added: “We are very excited to have started exploration on the San Luis lithium prospects. The initial remote exploration expects to identify pegmatites that are exposed at the surface, which will provide low-cost exploration targets for sampling and, if appropriate, drilling.”

 “Our long-term goal is to identify, explore and develop a substantial hard rock lithium resource, in  a country with an established lithium industry, good infrastructure and supportive regulatory and fiscal regimes. We will update shareholders on the exploration programme as we advance up the development curve. “

Desktop and fieldwork

The desktop and field work the geology team are undertaking is comprehensive and leverages high-tech equipment to the fullest extent. Key steps involved in the desktop review comprise the following:

  • Review all legacy reports that mention lithium mining and other minerals (beryl, tourmaline, muscovite, garnets) in Sans Luis, as this data can help determine the evolution of pegmatites in the area;
  • Use satellite imagery to map pegmatites/granite/other rocks of interest then determine accessibility from current road network and digitalise the information;
  • Identify pegmatites that are near known lithium mineralisation and historic mines then double check geophysics and radiometry to ensure they are viable targets;
  • From this data, calculate the number of prospective pegmatites in the area; and
  • Assess infrastructure requirements, especially accessibility on how to transport drilling equipment to prospective future areas of interest.

Upon completion of the desktop review, the geology team will visit pegmatites that are readily accessible to undertake field work. After all the field work data is collected, it will be reconciled with the geophysical and satellite imagery findings. This will enable the geology team to develop its sampling and XRF programme focused on the pegmatites with the highest probability of containing high-grade lithium mineralisation.

The next stage in the process will be securing regulatory approval to further the exploration programme.

Ownership

Cadence can acquire 100% of the interest in the exploration permits under application and will initially earn 49% via staged investments of cash spent on exploration and development and the issue of new ordinary shares in Cadence. Cadence has completed Stage 1 of the investment and currently indirectly owns 4% of the exploration permits under application.

Details of the commitments under the acquisition agreement with the vendors are summarised below

Stage Ownership % Total Ownership % Lithium Technologies Pty Ltd Lithium Supplies Pty Ltd Purpose
Stage 1 4% 4% £0.05 M £0.05 M Earn-in early non-invasive exploration (pre -exploration permits being granted)
Stage 2 20% 24% 95,153,846 shares in Cadence 57,692,308 shares in Cadence On grant of exploration permits – acquisition of Lithium Technologies and Lithium Supplies shares
Stage 3 7.5% 31.5% £0.15 M £0.15 M Earn – in on commencement of exploration works after grant exploration permits

The combination of this approach and seeking value opportunities allows us to identify projects capable of achieving high rates of return.

The Cadence board has a blend of mining, commodity investing, fund management and deal structuring knowledge and experience, that is supported by access to key marketing, political and industry contacts. These resources are leveraged not only in our investment decisions but also in continuing support of our investments, whether it be increasing market awareness of an asset, or advising on product mix or path to production. Cadence Mineral’s goal is to assist management to rapidly develop the project up the value curve and deliver excellent returns on its investments.

Cadence Minerals #KDNC acquires up to 100% of Hard Rock Lithium Prospects in Argentina

Cadence Minerals (AIM/NEX: KDNC; OTC: KDNCY) is delighted to inform shareholders that it has executed binding investment agreements with Lithium Technologies Pty Ltd and Lithium Supplies Pty Ltd to acquire up to 100% of six prospective hard rock lithium assets in Argentina.

These transactions mark the start of the Company’s strategic shift to earn in to early stage lithium assets in well-known lithium jurisdictions where we see the potential to deliver shareholder value by investing in projects that have shorter development timeline to cashflow than a typical lithium carbonate producer.

HIGHLIGHTS

  • The Vendors have claims over 55,773 hectares for six exploration permits within the known spodumene bearing pegmatite fields in San Luis Province, Central Argentina.
  • Initial site visit and reviews by Cadence have confirmed multiple pegmatite outcrops across the six claims. Some of these occurrences are proximate or along strike from known mineralised pegmatites that have been previously mined for lithium minerals (such as spodumene or lepidolite).
  • The pegmatite fields of San Luis have an important past record of producing mica, beryl, spodumene, tantalite (tantalum oxide), columbite (niobium oxide), and recently potassium feldspar, albite and quartz.
  • Historic mines outside of the claims have produced lithium oxide (“Li2O”) at grades ranging from 4.5% to 6.5%.
  • The properties have good access and infrastructure support for exploration activities on a year-round basis.
  • On grant of the exploration permits Cadence will acquire up to 49% by spending £1.1m on exploration and drilling, and by issuing £0.4 million of new ordinary shares in Cadence to The Vendors.
  • Cadence has an option to acquire up to 100% by issuing a further £1.75m of new ordinary shares in Cadence.

Kiran Morzaria, Chief Executive Officer of Cadence, commented: “These assets tick all the boxes that we were looking for: located in a well-known lithium producing country and in a large pegmatite field with known lithium compound production; potential to deliver quicker and cheaper development timelines and produce lithium oxide concentrate; near-term value triggers in the form of sampling and drilling and low cost in terms of the acquisition itself and the mineral exploration.”

Andrew Suckling, Executive Chairman of Cadence, added: “After an extensive review of opportunities, this acquisition enables us to deliver on our strategic objectives.It also provides us with an excellent platform to investigate building a larger portfolio of interests in a country with an established lithium industry, good infrastructure and supportive regulatory and fiscal regimes.  The presence of operators of the calibre of SQM and others in our view is a testament to this. The next year promises to be an exciting period for Cadence, and, we look forward to providing further updates on our progress in due course.”

New lithium assets

The Vendors have claims over a total of six hard rock lithium assets in San Luis Province, Central Argentina. Combined, the total area of the six assets is 55,773 hectares which delivers Cadence a large potentially mineralised footprint to ramp up exploration activities with the target of proving up a commercially viable JORC code compliant resource.

There are over a dozen historic mines (mined between 1936-80) in the Sans Luis area which produced lithium oxide at grades from 4.5% to 6.5% Li2O. In recent years, assay results taken from the spodumene outcrops across the region have returned results ranging from 5% up to 8.1% Li2O. Aggregating historic estimates for the legacy mines, there is an estimated 55,000 tonnes of lithium oxide. However, with the application of modern exploration techniques, we believe that there is potentially considerable exploration upside across the six assets.

More broadly, there are several other competitive advantages:

  • Readily accessible infrastructure – the assets are close to main roads, power lines, railroads, and small cities for labour and supplies; with highly competitive labour mining services available
  • Relatively low topographic height range and smooth fields enabling easy access to all project areas;
  • Mining friendly communities and active quarries provide advantages for exploration; and
  • No cities or lakes inside project areas which mitigates environmental issues to a large degree.

Background of the Lithium – Bearing Pegmatite Fields of San Luis

The San Luis and Córdoba lithium bearing pegmatite fields belong to the Pampean pegmatite province that was defined to include the economic fields of granitic pegmatites of central and north-western Argentina. It contains more than 95% of the granitic pegmatites of the country, with mineral resources that have been mined during the past 80 years, producing most of the potassium feldspar, quartz and mica plus Be‐, Li‐, Ta‐, Bi‐ and Rb‐ bearing minerals.

Of particular importance for hard rock lithium exploration are those pegmatite districts located in San Luis and western Córdoba.

Two parallel belts of Lithium-Caesium-Tantalum (“LCT”) pegmatites are found orientated NNE-SSW. In the western belt, pegmatites are enriched with Sn, whereas in the eastern belt pegmatites are Nb-Ta rich. The Sn-enriched pegmatite bodies were exploited for cassiterite during the 1940’s. The lithium mineralisation is predominantly represented by spodumene with minor amblygonite and lepidolite.

Future Work Program

We are looking to evaluate and define the most prospective targets across the six areas. Initially, this will focus on geological mapping, mineralogical studies of exposed pegmatites and the mapping and any newly identified historical workings. We anticipate we will be able to start this in Q1 of 2018.

This will be followed by an extensive sampling programme to identify any potential mineralisation, after which we can develop a drill programme with a target of identifying a JORC code compliant economic resource.

Argentine Background

Since 2015, reformist economic and political policies have placed Argentina back on the radar as a favourable investment destination: the economic landscape is improving while inflation is being tamed. Further, a US free trade deal has been negotiated, while debt issues are mostly resolved, and exchange controls eliminated, which has seen credit ratings improve.

For the mining sector, the government has eliminated export taxes on metals and allowed foreign-owned mining groups to repatriate profits overseas. More recently, the government signed a mining deal with 20 provincial governors to harmonise taxes and regulations to attract mining investment away from Chile and Peru.

Argentina is a growing lithium producer, and since 2015 Argentina has received more investment than any other country in the ‘lithium triangle’.  It is currently the world’s third-largest producer, with at least five new projects slated to come into production over the coming years.

Technical Glossary

The following is a summary of technical terms:

“amblygonite”

is a fluorophosphate mineral, composed of lithiumsodiumaluminiumphosphatefluorideand hydroxide. The mineral occurs in pegmatite deposits and is easily mistaken for albiteand other feldspars. Its density, cleavage and flame test for lithium are diagnostic.Geologic occurrence is in granite pegmatites and high-temperature tin veins. Amblygonite occurs with spodumeneapatitelepidolitetourmaline, and other lithium-bearing minerals in pegmatite veins. It contains about 10% lithium, and has been utilized as a source of lithium.

“beryl”

is a well-known mineral varieties of beryl include emerald and aquamarine. Naturally occurring, hexagonal crystals of beryl can be up to several meters in size.

“columbite”

is a black mineral group that is an ore of niobium. It has a submetallic lustre and a high density.

“deposit”

a coherent geological body such as a mineralised body

“exploration”

the method by which ore deposits are evaluated

“exploration permit”

Under the Argentine legislation, The holder of this right can explore an area during the period granted. In case of discovering mineral evidence, the holder has an exclusive right to apply for an exploitation concession. The only way to acquire an exploration permit is through an application to the proper mining authority to explore an area which is free of other mining tenements.

“geological map” & “geological mapping”

A geological map is a graphical presentation of geological observations and interpretations on a horizontal plane. Making, or otherwise acquiring, a geological map is invariably the first step in any mineral exploration programme, and it remains an important control document for all subsequent stages of exploration and mining, including drilling, geochemistry, geophysics, geostatistics and mine planning. They allow theories on ore deposit controls to be applied and lead (hopefully) to predictions being made on the location, size, shape and grade of potential ore bodies. They are the essential tool to aid in developing 3-dimensional concepts about geology and mineralisation at all scales.

“grade”

relative quantity or the percentage of ore mineral or metal content in an ore body

“JORC Code”

Joint Ore Reserve Committee Code; the Committee is convened under the auspices of the Australasian Institute of Mining and Metallurgy

“LCE”

the total equivalent amount of lithium carbonate (see explanation below entitled Explanation of Lithium Classification and Conversion Factors)

“lepidolite”

lilac-grey or rose-coloured member of the mica group of minerals. It is the most abundant lithium-bearing mineral. It is associated with other lithium-bearing minerals like spodumene in pegmatite bodies. It is one of the major sources of the rare alkali metalsrubidium and caesium. Associated minerals include quartzfeldsparspodumeneamblygonitecolumbitecassiterite, and beryl.

“Lithium-caesium-tantalum pegmatites” or “LCT pegmatites”

comprise a compositionally defined subset of granitic pegmatites; they are typically enriched with lithium caesium and tantalum. They are products of plate convergence and mountain building episodes. Most LCT pegmatites intruded metasedimentary rocks, typically at relatively low pressures and low temperatures.

“lithium”

a soft, silvery-white metallic element of the alkali group, the lightest of all metals

“lithium carbonate”

Lithium carbonate is an inorganic compound, the lithium salt of carbonate with the formulaLi2CO3. Lithium is extracted from primarily two sources: pegmatite crystals and lithium salt from brine pools. Lithium carbonate has many uses and is the primary lithium compound that is used in the manufacture of lithium-ion batteries.

“lithium oxide”

lithium oxide or lithia is an inorganic chemical compound. Lithium oxide is formed along with small amounts of lithium peroxide when lithium metal is burned in the air and combines with oxygen. Lithium oxide concentrate is produced from the mining and processing of spodumene ore.

“metallurgical”

describing the science concerned with the production, purification and properties of metals and their applications

“mica”

is a group of sheet minerals that have a layered or platy texture. Micas are used in a variety of applications. Mica’s value is based on several of its unique physical properties.

“Mineral Resource”

a concentration or occurrence of material of intrinsic economic interest in or on the Earth’s crust in such a form that there are reasonable prospects for the eventual economic extraction; the location, quantity, grade geological characteristics and continuity of a mineral resource are known, estimated or interpreted from specific geological evidence and knowledge; mineral resources are sub-divided into Inferred, Indicated and Measured categories

“mineralisation”

process of formation and concentration of elements and their chemical compounds within a mass or body of rock

“pegmatite”

A pegmatite is an intrusive igneous rock composed of crystals usually larger than 2.5 cm in size. Pegmatite bodies are usually of minor size compared to typical intrusive rockbodies. Pegmatite body size is on the order of magnitude of one to a few hundred meters. Compared to typical igneous rocks they are rather inhomogeneous and may show zones with different mineral assemblages. Crystal size and mineral assemblages are usually oriented parallel to the wall rock or even concentric for pegmatite lenses. Pegmatites are the primary source of lithium either as spodumene or lepidolite.

“processing” or “mineral processing”

is the science of treating crude ores and mineral products in order to separate the valuable minerals from the waste rock. It is the first process that most ores undergo after mining in order to provide a more concentrated material for the procedures of extractive metallurgy. The primary operations are comminution and concentration, but there are other important operations in a modern mineral processing plant

“recovery”

the proportion of valuable material obtained in the processing of an ore, stated as a percentage of the material recovered compared with the total material present

“spodumene”

is a pyroxene mineral consisting of lithium aluminium inosilicate, and is a source of lithium. It occurs as colourless to yellowish, purplish, or lilac kunzite (see below), yellowish-green or emerald-green hiddenite, prismatic crystals, often of great size. Spodumene is an important source of lithium for use in ceramicsmobile phone and automotive batteriesmedicine and as a fluxing agent. Lithium is extracted from spodumene by fusing in acid.

“ore”

is a type of rock that contains sufficient minerals with important elements including metals that can be economically extracted from the rock. The ores are extracted from the earth through mining; they are then refined to extract the valuable element, or elements.

“tantalite”

is the primary source of the chemical element tantalum. It is chemically similar to columbite, and the two are often grouped together as a semi-singular mineral called coltan or “columbite-tantalite” in many mineral guides.

Lithium Classification and Conversion Factors

Lithium grades are normally presented in percentages or parts per million (ppm). Grades of deposits are also expressed as lithium compounds in percentages, for example as a per cent. lithium oxide (Li2O) content or per cent. lithium carbonate (Li2CO3) content.

Lithium carbonate equivalent (“LCE”) is the industry standard terminology for, and is equivalent to, Li2CO3. Use of LCE is to provide data comparable with industry reports and is the total equivalent amount of lithium carbonate, assuming the lithium content in the deposit is converted to lithium carbonate, using the conversion rates in the table included further below to get an equivalent Li2CO3 value in per cent. Use of LCE assumes 100% recovery and no process losses in the extraction of Li2COfrom the deposit.

Lithium resources and reserves are usually presented in tonnes of LCE or Li.

The standard conversion factors are set out in the table below:
