Lithium Argentina hits guidance high-end with record Q4 production

Lithium Argentina AG (NYSE:LAR) shares are in focus after the company announced standout preliminary 2025 results for its Cauchari-Olaroz operation.

The project, a joint venture with Ganfeng Lithium, achieved full-year production of 34,100 tonnes of lithium carbonate—reaching the upper limit of its 30,000–35,000 tonne guidance.

The fourth quarter was particularly transformative, delivering a record 9,700 tonnes while operating at a 97% nameplate capacity.

This ramp-up in volume has successfully driven down costs.

The company expects Q4 cash operating costs to fall below $6,000 per tonne, a notable improvement from the $6,285 per tonne reported in Q3.

This efficiency gain positions the asset as one of the most resilient low-cost brine operations in the global market.

Financially, the company bolstered its balance sheet by reducing net debt by $26 million during the final quarter of 2025.

With over $150 million in total liquidity, Lithium Argentina is pivoting toward its next phase of growth.

Meanwhile, the company has officially submitted its Stage 2 RIGI application (Argentina's Large Investment Incentive Regime) for an expansion to 45,000 tpa, with a similar application for the Pozuelos-Pastos Grandes (PPG) project expected by March 2026.
