Argentina’s Kachi Lithium Project: Poised for Production in 2026
Lake Resources is on track to receive Argentine government approval and secure final investment for its Kachi lithium project in 2026, a development fueled by rising lithium demand and improving economic conditions in Argentina. The US$1.16 billion project is anticipated to initiate production within 30 months of receiving the final investment decision (FID).
Direct Lithium Extraction (DLE) Technology: A Game Changer
The Kachi project will utilize ion-exchange technology from Lilac Solutions for lithium extraction. This method offers significant advantages over traditional evaporation pond techniques, notably reducing freshwater consumption and improving brine treatment, productivity, and recovery rates. Lilac Solutions holds a 20% stake in Kachi, facilitating the validation of this direct lithium extraction (DLE) technology.
DLE technology is gaining traction as a more sustainable and efficient alternative to conventional methods. Reproducing operating conditions and adhering to strict protocols are crucial for successful DLE implementation, as highlighted by Andrés González, general manager of the National Pilotage Center in Chile.
Strategic Advances and Resource Expansion
Lake Resources has made substantial progress in de-risking the Kachi project. Key achievements in 2025 include increasing the lithium carbonate equivalent (LCE) resource to 11.1Mt, completing the definitive feasibility study for phase 1, and securing engineering agreements for power supply from the national grid through a partnership with YPF Luz. Crucially, the Carachi Pampa lagoon, essential to the project, has been authorized for regulated productive use by the Catamarca government.
Favorable Economic Climate Boosts Investment
Argentina’s improving economic landscape is creating a more attractive environment for foreign direct investment. Inflation has decreased from 117% in 2024, and the government is actively pursuing agreements to address debt and fiscal deficits. The recent finalization of the Mercosur-European Union free trade agreement and a realignment of relations with the United States further contribute to a positive outlook.
Lithium Price Rebound and Demand Surge
A significant rebound in lithium prices between mid-November 2025 and February 2026, with prices reaching an average of US$21,924/t in Chinese and Australian markets, is expected to further stimulate investment. Analysts at Goldman Sachs and BMI have likewise revised their lithium price projections upwards for 2026-2030.
Global lithium demand is projected to double between 2025 and 2030, driven by the growth of battery energy storage systems (BESS) and continued demand for electric vehicles in Asia and Europe. Kachi is well-positioned to capitalize on this increasing demand.
Kachi’s Production Profile
Phase 1 of the Kachi project is expected to yield approximately 23,000 tonnes of lithium carbonate (LCE) in the first year of production, scaling up to 25,000 tonnes – its nameplate capacity – in the following year. A second phase is planned to add an additional 25,000 tonnes of LCE production capacity.
