• Mineral Resource Increase

  Measured and Indicated Mineral Resources increased by 60% to 25.9 million tonnes LCE, with Inferred Resources rising by 104% to 9.6 million tonnes LCE, driven by new drilling and an updated hydrological model.

• Mineral Reserve Update & Stage 2 Plan

  Total Mineral Reserves are 1.4 million tonnes LCE over 35 years, a 28% reduction from previous estimates, but Proven Reserves increased by 45%. This re-scoping supports a Stage 1 production of 40,000 tpa LCE, with plans for a Stage 2 expansion to over 80,000 tpa LCE using DLE technology.

• Improved Lithium Recovery

  Overall lithium recovery efficiency has improved from 53.7% to 63% based on demonstrated operating performance.

• Increased Operating Costs

  Operating costs are estimated at $5,411 per tonne LCE, a substantial increase from the previous $3,579 per tonne, attributed to inflation and local currency devaluation.

Lithium Argentina AG has released a comprehensive S-K 1300 Technical Report for its Cauchari-Olaroz project, revealing a substantial 60% increase in Measured and Indicated Mineral Resources to 25.9 million tonnes of Lithium Carbonate Equivalent (LCE). This significant expansion of the resource base, driven by new drilling and a basin-wide hydrological model, underpins the company's long-term growth potential. While total Mineral Reserves saw a 28% reduction to 1.4 million tonnes LCE over a 35-year mine life, this is a strategic re-scoping for Stage 1 operations (40,000 tpa LCE) to preserve capacity for a planned Stage 2 expansion targeting over 80,000 tpa LCE using new DLE technology. Notably, Proven Mineral Reserves increased by 45%, reflecting enhanced certainty from production history and updated modeling. The report also highlights an improved lithium recovery rate from 53.7% to 63%. However, operating costs have increased significantly from $3,579 to $5,411 per tonne LCE, primarily due to inflation and local currency devaluation, which will impact profitability. The project's capital expenditure is confirmed at $979 million, already expended. The market outlook for lithium remains positive, driven by strong demand from electric vehicles and battery energy storage systems.
