Lake boosts Kachi lithium resource
Lithium developer Lake Resources has announced a substantial increase in the resource estimate for its flagship Kachi project, in Argentina.
Measured and indicated resources have increased from 2.9-million tonnes to 7.3-million tonnes of lithium-carbonate equivalent (LCE) defined to a depth of 600 m over 143.8 km2.
The updated total resource estimate exceeds 10.6-million tonnes of LCE.
The resource update, announced on Tuesday, will be used in the hydrogeologic model for the forthcoming maiden reserve estimate and will be the basis for the project Phase 1 definitive feasibility study (DFS), expected in December.
“Our expansive hydrogeological characterization programme over the last year-and-a-half has led to significant improvements in our understanding of the geology, hydrogeology and geochemistry of the Carachi Pampa basin,” said geology and hydrogeology director Michael Gabora.
The resource update incorporates the vertically expansive lithium intersects of the last six months and includes exceptional lithology and lithium concentrations intersected at K24D41.
The footprint of the lithium brine extent has been growing dramatically to the north, south and, most important, vertically.
The consistency of the lithium concentration and brine chemistry in the new step-out holes demonstrates how well the brine has circulated and mixed within the basin.
The new results build on the strong track record of continued resource growth since the maiden resource estimate first announced in November 2018.
“Our improved hydrogeologic understanding of the system will allow us to develop an optimal extraction and recovery strategy to allow for responsible development of clean lithium in the basin while minimizing the consumption of water and related hydrologic impacts,” Gabora said.
