Lithium Argentina (LAR) Reports 42% Increase in Lithium Resource to 28.1M Tonnes

Lithium Argentina (NYSE:LAR) is one of the best hot stocks to buy according to analysts. On March 11, Lithium Argentina announced an updated mineral resource and reserve estimate for its Cauchari-Olaroz brine operation in Jujuy Province, Argentina. The updated figures show a 42% increase in Measured and Indicated resources, now totaling 28.1 million tonnes of lithium carbonate equivalent/LCE with an average grade of 562 mg/L. This expansion was driven by a basin-wide hydrological model and new drilling that extended the resource area ~20 kilometers south of the previous footprint.

The new data is intended to support the Company’s Stage 2 development plans, which target an additional 45,000 tonnes per annum (or tpa) of LCE on top of the current Stage 1 capacity of 40,000 tpa. To facilitate this growth, Lithium Argentina filed applications for environmental permits and the Incentive Regime for Large Investments/RIGI in December 2025. A comprehensive technical report detailing these estimates is expected to be filed in March this year, with an updated Stage 2 development plan following in mid-2026.

Operationally, Stage 1 continues to perform near capacity with production costs maintained below $6,000 per tonne. The updated reserve model reaffirms a 35-year operating period from 2026 to 2060, aligning with the project’s original 40-year lifespan after accounting for prior production. Lithium Argentina (NYSE:LAR) stated that these results strengthen its goal of achieving a combined regional capacity of over 200,000 tpa LCE by using existing infrastructure and new technologies.
