Recent operational updates have shown the methodical and sustained progress at the Kachi site.
Based on conclusions following a rigorous assessment of the project, Lake reset the production plan, timelines, and estimated costs of the Kachi project. The new approach significantly de-risks the project, with a phased development plan to target plant capacity of 50,000 tpa battery grade lithium carbonate.
Key target milestones and estimates for Kachi are outlined below: - Two phases of 25,000 tpa each; - On track for submission of Initial DFS for Phase 1 targeting capacity for 25,000 tpa battery gradelithium carbonate; - First lithium production targeted for 2H 2027.
EIA Submission for Phase 1 was reported to the Catamarca Ministry of Mining on March 26, 2024. |

Summary:
The known sediments within the salar consist of salt/halite, clay, sand and silt horizons, accumulated in the salar from terrestrial sedimentation and evaporation of brines. Brines within the Salt Lake are formed by solar concentration, interpreted to be combined with warm geothermal fluids, with brines hosted within sedimentary units. Geology was recorded during the diamond drilling and from chip samples in rotary drill holes.
The Salar de Carachi Pampa is located within a large hinterland water catchment that focuses water flows into the closed drainage intermontane Carachi Pampa basin of about 9,500 km2. In particular, it drains the lithium bearing volcanic rocks of Cerro Galan volcano and associated hot springs, which is also interpreted to be the source of lithium for the Livent’s Fenix lithium brine project production at Salar de Hombre Muerto, about 110 km north of Kachi.
The Carachi Pampa basin is bounded to the east and west by NNE-SSW trending mountain ranges that have been raised by reverse faults to expose a basement sequence of rocks that rise to an elevation of 5,100 metres. The ranges are formed from Ordovician Falda Cienaga Formation comprising green-grey turbidites in outcrop, Permian Pataquia Formation, a red-bed sedimentary unit, and beige-green Eocene-aged Geste Formation of continental fluvial sediments.
The Carachi Pampa salt lake is rhomboidal in shape with a NW-SE long-axis, and covers a known surface area of about 135 ........
Summary:
The conceptual mining method is recovering brine from the Salt Lake via a network of wells, the established practice on existing lithium and potash brine projects.
