Lake Resources (LK1.DU) has announced a significant expansion of the Kachi lithium resource, with a 250% increase in measured and indicated resources ahead of the definitive feasibility study. The project now boasts 7.3 million tonnes of lithium carbonate equivalent (LCE) to a depth of 600 metres across 143.8 sq.km.
Substantial Growth in Kachi Lithium Resources
The updated figures mark a substantial leap from the June estimate of 2.9 million M+I tonnes LCE. Including inferred resources, Kachi’s total resource estimate now stands at over 10.6 million tonnes of LCE.
This growth stems from an extensive hydrogeological program that has enhanced the company’s understanding of the Carachi Pampa basin’s geology and hydrogeology. Michael Gabora, the director of geology and hydrogeology, emphasized the development of an optimal extraction strategy that prioritizes responsible and sustainable lithium production.
Advancements in Drilling and Resource Understanding
Recent drilling has targeted step out holes and deeper resources, with borehole K24D41 revealing high-grade lithium concentrations. The consistent brine chemistry across new holes indicates effective circulation within the basin, complemented by additional surface geophysical surveys.
The company plans to incorporate these findings into the hydrogeologic model for the upcoming maiden reserve estimate and the Phase 1 definitive feasibility study.
Global Ranking and Strategic Partnerships
The Kachi project is now among the top 10 global brine resources, with the potential to produce high-purity lithium carbonate. Lake Resources’ partnership with Lilac Solutions aims to leverage technology and funding to advance the lithium brine project.
