Option Exercised on +70,000 Ha Pegmatite Lithium Catamarca Project
Option Exercised on +70,000 Ha Pegmatite Lithium Catamarca Project
Brisbane, Sep 25, 2018 AEST (ABN Newswire) - Argentine-focused lithium exploration and project development company Lake Resources NL (ASX:LKE) has taken the decision to exercise the option over a large belt of outcropping pegmatites in the Ancasti area of Catamarca province, Argentina (see figures 1, 2 and 3 in link below).

- Pegmatites in Catamarca a likely host for significant lithium mineralisation as spodumene.

- Decision made to exercise option and acquire project 100% of 70,000 hectare project.

- Recent field programme suggests a number of potential targets in a 150km mineralised belt.

- District in Catamarca has seen previous small scale production. Lake is using modern techniques to locate potential new large scale deposits.

A recent field programme has reinforced the view that the 150 kilometre-long belt favourably hosts significant lithium mineralisation as spodumene in large pegmatite swarms.

Lake signed an agreement with Argentine company, Petra Energy SA, in early 2017 over an area of exploration lease applications exceeding 70,000 hectares within a belt of outcropping pegmatites over 150 kilometres long.

A total of 19 million ordinary LKE shares will be issued to the vendors to acquire 100% of the local company and the project, of which 50% of the shares will be escrowed for 6 months. Previously only 1 million shares were issued, on signing of the option agreement in 2017, with the remainder to be issued in the coming days.

Recent field work in the Ancasti area has resulted in new exploration models being developed which clearly show potential for the belt to host large scale deposits. Previously, coarse grained spodumene crystals 30-70cm long had been identified in a number of locations. Further exploration activities will be conducted once the transaction is completed. Field based XRF analysis to vector in on potential new targets will be undertaken first, followed by trenching and auger sampling. Drill locations will then be defined by these results.

Managing Director Steve Promnitz said: "The pegmatite project in Catamarca is an enormous target with lots of exploration upside. We secured the project because the geology is very compelling and there is a history of production in the area. We have had considerable interest from third parties, both foreign and local Argentine companies, wanting to jointly explore Catamarca and we'll assess these carefully."

"Our in-country exploration team expects to commence work very soon on sampling and this will not inhibit progress being made at Kachi and Cauchari which are both on track and progressing to plan."

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.
