Lake Resources NL Drilling at Kachi Project Strengthens Scale and Quality of Lithium Brines


The results will be used in the preparation of a first mineral resource.

Lake Resources NL (ASX:LKE) has extended drilling activities at its Kachi Lithium Brine project in Argentina, with results indicating consistent brine chemistry so far.

The drilling program is progressing towards an initial resource estimate, which is expected to be completed in October, and another hole is planned.

Geochemistry similar to major projects

Recent drilling has returned between 250 and 276 milligrams per liter of lithium over 42 meters, with the best dosage to date of 306 milligrams per liter over 239 meters.

Lithium brine is present in sandy sediments from surface to over 400 meters depth, in over 14 rotary and diamond drill holes.

Analytical results in the best drill hole show encouraging densities with a favorable magnesium to lithium ratio of 4.3.

This ratio is similar to other major Argentine projects operated by Galaxy Resources Ltd (ASX:GXY) and Neo Lithium Corporation (CVE:NLC).

The area around this hole is a key target for ongoing research as it potentially contains very deep lake sediments.

Resource estimation work in progress

The drilling intersected different interbedded lithologies dominated by sandy sediments.

Samples have been taken for porosity testing, these are to be included in the next resource estimate along with systematic brine analyses.

The Kachi project covers more than 50,000 hectares of mining leases and is owned by Lake’s Argentinian subsidiary, Morena del Valle Minerals SA.

These leases are held in the center of the known salt lake of Kachi, in the deepest part of the basin.

Surface sampling initially revealed positive results for lithium in brines, which was supported by positive results from drilling and geophysical programs.
