KACHI

Lake Resources announced on 19 December 2023 the results of its Definitive Feasibility Study (DFS) for Phase One of the globally significant Kachi lithium brine project in Argentina.

Lake Resources announced on 4 August 2025 an addendum (DFS Addendum) to its 19 December 2023 Definitive Feasibility Study (DFS) for Phase One of the globally significant Kachi lithium brine project in Argentina, showing material capital and operating cost estimate reductions.

The Original DFS and DFS Addendum demonstrate that Kachi is a top tier project, backed by a significant resource and strong economics positioning it competitively within the growing lithium market.

PROJECT AND RESOURCE HIGHLIGHTS

• Total resource is estimated at 11.1 Mt LCE, a globally significant resource.
• DFS Addendum design basis brine grade of 249 mg/L and updated Ore Reserve statement showing an improvement to 268 mg/L.
• 25-year mine life supported by the updated Ore Reserve statement.
• Phase One targets production of 25 thousand tonnes per annum (ktpa) over the LoM to meet the growing demand and specifications of the battery market.
• Improved DLE process tailored to mitigate impact on the local community with minimal disruption to land, freshwater table, and water usage.
• The project targets production of consistent battery-grade lithium carbonate (>99.5% purity) at site without the need for further refining or processing.
• Long-term pricing forecasts used in the DFS are reflective of the forecasted lithium supply deficit.
• Derisked project execution plan, including a viable solution for grid power availability.
