Met testing update: High recoveries; high concentrate grade
LRS announced an update from ongoing metallurgical test work
being competed on Salinas lithium mineralisation. Highlights from sample testing to date
are:
• Coarse crush size of 12.5mm resulted in an average Li2O recovery of 80.5% and
production of an extremely high-grade concentrate (up to 6.6% Li2O) from Heavy Liquid
Separation processing alone;
• Relatively consistent results across the width and depth of the known orebody;
• Minimal fines generation, potentially resulting in a low reliance on flotation as part of the
processing flow sheet; and
• Low iron grades, resulting in a higher value-in-use end product.
LRS are now progressing with a bulk pilot plant test-work to optimise the flowsheet which
will be assessed as part of a Preliminary Economic Assessment due in the March 2023
quarter.
