Lithium Argentina filed a Form 6-K furnishing a detailed S-K 1300 scoping study for its PPG Salars lithium brine project in Salta, Argentina. The report outlines total measured and indicated resources of 14,580,305 tonnes of lithium carbonate equivalent (LCE) and inferred resources of 6,714,899 tonnes across Pozuelos and Pastos Grandes.
The development concept targets three phases producing about 51,000 tonnes per year of LCE each, for total planned output of 153,018 tonnes per year over a nominal 30-year life. Total capital cost is estimated at US$3,301,209,207, with steady-state operating costs of US$5,027 per tonne LCE and assumed long-term prices of US$18,000 per tonne lithium carbonate and US$17,800 per tonne lithium hydroxide monohydrate.
Including Argentine RIGI incentives, the project shows an after-tax Net Present Value of US$5,766,032,301 at a 10% discount rate and a 32.7% internal rate of return, with an estimated five-year payback. No mineral reserves are defined yet, but groundwater models and planned wellfields support production planning, and qualified persons report no known legal, political, or environmental risks that would materially affect resource development.
Lithium Argentina reported a major update to the Cauchari-Olaroz lithium brine project, increasing total measured and indicated resources by 42% to 28.1 Mt LCE at an average grade of 562 mg/L. Inferred resources more than doubled to 9.6 Mt LCE.
The new Technical Report also outlines 1.4 Mt LCE of proven and probable reserves, supporting Stage 1 production of 40,000 tpa LCE over an additional 35-year period from 2026–2060. Stage 1 is currently operating near its 40,000 tpa capacity with costs under $6,000 per tonne, versus reserve economics based on $18,000/tonne long-term pricing and operating costs of $5,411/tonne.
The company is advancing a Stage 2 plan targeting an extra 45,000 tpa LCE, with environmental permits and an application under Argentina’s RIGI incentive regime submitted in December 2025 and a Stage 2 scoping study expected by mid-2026.
