Lake Resources' drilling at Kachi project reinforces scale and quality of lithium brines

The results will be used in the preparation of a maiden mineral resource.
Lake Resources' drilling at Kachi project reinforces scale and quality of lithium brines
The Kachi project is in Argentina's Catamarca Province

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

The drill program is advancing towards an initial resource estimate, anticipated to be complete in October, and has one further hole planned.

Similar geochemistry to major projects

Recent drilling returned results between 250-276 milligram per litre lithium over 42 metres, with the best assay to date 306 milligram per litre over 239 metres.

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

Analytical results in the best drill hole display encouraging densities with a favourable magnesium:lithium ratio of 4.3.

This ratio is similar to that of other large 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 investigation as it potentially has very deep lake sediments.

Resource estimate work ongoing

Drilling has intersected different interlayered lithologies which are dominated by sandy sediments.

Samples have been collected for porosity tests, with these to be included in the upcoming resource estimate along with systematic brine analyses.

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

These leases are held over the centre of the known Kachi salt lake in the deepest part of the basin.

Surface sampling had initially revealed positive lithium results in brines, which has been supported by positive results from drilling and geophysical programs.
