Large Maiden 4.4mt LCE Resource Estimate for Kachi Project
Large Maiden 4.4mt LCE Resource Estimate for Kachi Project
Brisbane, Nov 28, 2018 AEST (ABN Newswire) - Argentine-focused lithium exploration and project development company Lake Resources NL (ASX:LKE) is pleased to release a large maiden resource estimate for Lake's 100% owned Kachi Lithium Brine Project in Argentina (see Figure 1 in link below).

- Maiden Mineral Resource estimate of 4.4 million tonnes of contained Lithium Carbonate Equivalent in Inferred and Indicated Categories extending to 400m below ground level in porous, permeable sediments.

- Indicated Mineral Resource estimate of 1.0 million tonnes of Lithium Carbonate Equivalent (LCE) in the central area of Kachi.

- Inferred Mineral Resource estimate of 3.4 million tonnes LCE in the surrounding area.

- Estimate based on results of 15 drill holes. Brine bearing sediments remain open at depth and laterally with opportunity for resource expansion from additional deeper drilling and extending the area of exploration drilling.

- Resource estimate centred within an exploration target with potential for 8 to 17 million tonnes LCE over 20 km x 15km with brines from surface to 400+ metres depth, demonstrating scale of the project of a similar size to globally significant lithium producers.

The maiden resource estimate contains 1 Mt of lithium carbonate equivalent (LCE) as Indicated resources, and 3.4 Mt of LCE as Inferred resources, with a resource depth of 400m for both areas (see Table 2 in link below).

Lake Resources Managing Director Steve Promnitz said: "We are very pleased to report such a significant maiden JORC Mineral Resource estimate for Kachi. The team advanced drilling within 12 months on an undrilled project, and defined a large resource and located a project that stands alongside the largest lithium projects in Argentina."

"We will expand the resource with more drilling and move into a pre-feasibility study using conventional and a direct extraction technology from Lilac Solutions which indicate high recoveries, low costs and a reduced time to production of lithium."

Project Background

Lake Resources' 100%-owned Kachi Lithium Brine Project in Catamarca province, Argentina covers 69,000 hectares (170,000 acres) with 36 mining leases owned by Lake's Argentine subsidiary, Morena del Valle Minerals SA. These are held over the centre and southern extension of the salt lake at Kachi in the lowest point (around 3000 m altitude) of a large drainage area of approximately 6800 square kilometres (2500 square miles). The basin drains the lithium bearing volcanic rocks of Cerro Galan, which is interpreted to provide the lithium for the FMC Lithium (Livent) production at Hombre Muerto, together with hot springs. Surface samples with positive lithium results in brines were explored at depth through the drilling and geophysics programs.

Drilling at Kachi has returned positive lithium values in the southwest of the project, where the passive seismic geophysics suggests the basin is the deepest, and brine extends under cover to the south.

Resource Summary

The company has to date drilled 15 brine investigation drill holes to depths of up to 403m across principal target areas of the Kachi salt lake (see Figure 1 in link below). This has revealed thick permeable sand dominated sediments that are expected to continue below current drilling depth limits and beyond the surface dimensions of the salt lake. The ongoing 2017-2018 investigation program has completed a total of 3150m of drilling to date, comprising diamond drill holes, rotary wells and installation of test production bores. The table in link below and Table 2 (see link below) outline the resource reported in accordance with the JORC Code (2012) and estimated by a Competent Person as defined by the JORC Code.

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.
