Brine Drilling Progressing Well at Kachi Lithium Brine Project
- Drilling has intersected brine in a second drillhole within brines below the lithium bearing salt lake of the 100%-owned Kachi Lithium Brine Project in Catamarca Province, Argentina
- The second diamond drillhole is below 125m depth in permeable sandy horizons containing brines with promising conductivities and densities
- Initial assay results from the brines are anticipated in early January
These brines display encouraging conductivities and densities - positive indicators for future results. Initial assay results are anticipated in early January. The second drill hole is at 126m depth and planned to continue to below 250m after the Christmas recess (12 days) to test deeper aquifers. The first hole was terminated at 71m after testing the near surface aquifer. These holes are part of a maiden 1,000m diamond drilling programme. The programme can be extended pending the outcome of assay results.
After returning from site this week, Lake Resources' Managing Director Steve Promnitz said: "Drilling has intersected brine saturated sediments from a metre from surface, which includes significant permeable sands. The first set of assay results will be reported as soon as possible. Activity in the lithium sector has intensified with a neighbouring project under a takeover offer on market for C$265 million. This bodes well for Lake given the scale of the four projects in Argentina's Lithium triangle and the fact that they are 100% owned."
The Kachi Lithium Brine Project covers over 50,000 ha of mining leases owned 100% by Lake's Argentine subsidiary, Morena del Valle Minerals SA, over the centre of the known salt lakes in the deepest part of a large basin. Surface sampling has revealed positive lithium results in conductive brines which will be expanded through the drilling program and geophysics.
The company has a focus on an inclusive approach with local communities together with appropriate environmental management. The Kachi Project was selected by the State of Catamarca to be accelerated, together with a small group of energy and mining projects in the province, to ensure appropriate development. A Letter of Intent was signed with Catamarca Province to facilitate the project through various permitting stages from exploration to production which bodes well for the future.

About Lake Resources NL
Lake Resources NL (ASX:LKE) is a lithium exploration and development company focused on developing its three lithium brine projects and hard rock project in Argentina, all owned 100%. The leases are in a prime location among the lithium sector's largest players within the Lithium Triangle, where half of the world's lithium is produced. Lake holds one of the largest lithium tenement packages in Argentina (~200,000Ha) secured in 2016 prior to a significant 'rush' by major companies. The large holdings provide the potential to provide consistent security of supply demanded by battery makers and electric vehicle manufacturers.
The Kachi project covers 69,000 ha over a salt lake south of FMC's lithium operation and near Albemarle's Antofalla project in Catamarca Province. Drilling at Kachi has confirmed a large lithium brine bearing basin over 20km long, 15km wide and 400m to 800m deep. Drilling over Kachi (currently 16 drill holes, 3100m) has produced a maiden indicated and inferred resource of 4.4 Mt LCE (Indicated 1.0Mt and Inferred 3.4Mt) within a 8-17 Mt LCE exploration target (refer ASX announcement 27 November 2018).
A direct extraction technique is being tested in partnership with Lilac Solutions, which has shown 80-90% recoveries and lithium brine concentrations in excess of 3000 mg/L lithium and is planned to be trialled on site in tandem with conventional methods as part of a PFS to follow the resource statement. Scope exists to unlock considerable value through partnerships and corporate deals in the near term.
The Olaroz-Cauchari and Paso brine projects are located adjacent to major world class brine projects either in production or being developed in the highly prospective Jujuy Province. The Olaroz-Cauchari project is located in the same basin as Orocobre's Olaroz lithium production and adjoins Ganfeng Lithium/Lithium Americas Cauchari project, with high grade lithium (600 mg/L) with high flow rates drilled immediately across the lease boundary.
Two drill rigs are currently drilling at Cauchari with results anticipated to extend the proven resources in adjoining properties into LKE's area with results anticipated from November into December 2018. This will be followed by drilling extensions to the Olaroz area in LKE's 100% owned Olaroz leases.
Significant corporate transactions continue in adjacent leases with development of Ganfeng Lithium/Lithium Americas Cauchari project with Ganfeng announcing a US$237 million for 37% of the Cauchari project previously held by SQM. Nearby projects of Lithium X were acquired via a takeover offer of C$265 million completed March 2018. The northern half of Galaxy's Sal de Vida resource was purchased for US$280 million by POSCO in June 2018. These transactions imply an acquisition cost of US$55-110 million per 1 million tonnes of lithium carbonate equivalent (LCE) in resources.
The demand for lithium continues to be strong for lithium ion batteries in electric vehicles, according to recent data from the leading independent battery minerals consultant, Benchmark Mineral Intelligence. Supply continues to be constrained suggesting good opportunities for upstream lithium companies.
