ZUG, Switzerland, Aug. 05, 2026 (GLOBE NEWSWIRE) -- Lithium Argentina AG (“ Lithium Argentina ” or the “ Company ”) ( TSX: LAR ) ( NYSE: LAR ) today announced that the Cauchari-Olaroz lithium brine operation, held through Minera Exar S.A. (“ Cauchari-Olaroz ” or the “ Operation ”), has closed on $220 million of new unsecured debt facilities (“ Debt Facilities ”), further strengthening its financial position and enhancing funding flexibility as it continues to advance an expansion plan to increase production capacity by an additional 45,000 tonnes per annum of lithium carbonate equivalent (“ Stage 2 ”). All monetary amounts in this news release are expressed in U.S. dollars.

The Debt Facilities consist of:

$50 million facility: closed in June 2026 with a two-year term, to replace existing short-term credit facilities.

$170 million facility: closed in August 2026, with a syndicate of international banks. The $170 million credit facility has a three-year term with an interest rate under 5%.

Sam Pigott, CEO of Lithium Argentina, commented: “These financings – unsecured and attractively priced - reflect confidence in Cauchari-Olaroz, the strength of our partnership with Ganfeng and the strong cash flow generation from the Operation. Together with the recent RIGI approval, the new Debt Facilities strengthen our balance sheet and provide the funding flexibility to advance our long-term growth strategy. We look forward to sharing further detail on Stage 2 as we complete the updated development plan in the coming months.”

The Debt Facilities are unsecured, provide flexibility for further distributions from Cauchari-Olaroz, support additional debt capacity (including project debt) and are available for drawdown until second quarter of 2027. They are supported by a guarantee from Ganfeng Lithium Co., Ltd (“ Ganfeng ”) with Lithium Argentina providing a counter-guarantee to Ganfeng for 49% of the debt outstanding.

The Debt Facilities form part of Lithium Argentina’s broader strategy to optimize its capital structure by utilizing debt financing at the operating asset level, while reducing debt at the corporate level. This approach is expected to improve financing efficiency and provide additional flexibility from both tax and foreign exchange management perspectives.

Next Steps

Stage 2 permitting: the environmental permit application was submitted in December 2025, underpinned by the completion of a basin-wide hydrogeological resource model that supports the Stage 2 production capacity.

Stage 2 development plan: technical and engineering studies are ongoing, with results of an updated development plan expected in the coming months.
