TSX- and NYSE-listed Lithium Argentina says its Cauchari-Olaroz operation delivered a strong and consistent operating performance last year, achieving production at the high end of yearly guidance and record quarterly production in the fourth quarter.

The Argentina-based lithium mine produced 34 100 t of lithium carbonate for the year, in line with guidance of between 30 000 t and 35 000 t.

Output in the fourth quarter reached a record 9 700 t with an average operating rate of 97% nameplate capacity.

Moreover, cash operating costs are expected to be below $6 000/t of lithium carbonate sold, compared with an operating cash cost of $6 285/t during the third quarter, which reflects continued operational optimisation and higher production volumes.

Lithium Argentina currently has more than $150-millionin liquidity from cash and undrawn facilities, with the company aiming to reduce net debt by $26-million.

Meanwhile, the company submitted an environmental permit application for the Stage 2 expansion of the operation to produce 45 000 t/y of lithium carbonate.

Lithium Argentina also applied for the project to be included in Argentina’s Regime for Large Investments (RIGI), which would afford the company long-term tax stability, import duty exemptions, value-added tax benefits and foreign exchange flexibility.

The company is also submitting a RIGI application for the Pozuelos-Pastos Grandes project soon – this project is located in the Salta province of Argentina and is also a high-potential lithium brine project.

CEO Sam Pigott comments that the performance achieved at Cauchari-Olaroz in 2025 represents a significant milestone, reflecting the successful establishment of Argentina’s largest lithium operation and another year of disciplined execution across the organisation.

“Strong production through the fourth quarter, together with continued cost reductions, highlights the increasing operational maturity of the business and positions us well for the next stage of growth as we advance Stage 2 at Cauchari-Olaroz and progress the Pozuelos-Pastos Grandes project.”
