General Motors Holdings LLC and General Motors Company have fully exited their reportable stake in Lithium Argentina AG. On March 26, 2026, GM Holdings sold 15,002,245 common shares in a block sale at $5.85 per share. Following this transaction, the reporting persons now report beneficial ownership of 0 common shares, representing 0% of Lithium Argentina’s outstanding common shares, so they are no longer more-than-5% holders.
Lithium Argentina has entered into a loan agreement with GFL International, a Ganfeng subsidiary, under which the lender may provide up to US$130 million. The loan carries a six-year term from the initial advance (no later than December 31, 2032) and bears interest at SOFR plus 2.5%.
Advances cannot start before October 1, 2026 and must primarily fund repayment or refinancing of the company’s US$258.75 million convertible notes due in January 2027. The facility is secured by a first‑priority pledge over the company’s shares in Millennial and its equity interest in the consolidated Pozuelos‑Pastos Grandes projects. While the loan is outstanding, Lithium Argentina has agreed to allocate up to 6,000 tonnes per year of lithium carbonate equivalent from Cauchari‑Olaroz and later up to 50% of its Phase 1 offtake (capped at 6,000 tonnes) from the new PPG joint venture to Ganfeng at market prices, and to use specified Minera Exar distributions to repay the loan.
Lithium Argentina reported 2025 results showing strong lithium production growth at Cauchari-Olaroz but a wider consolidated loss. The operation produced about 34,100 tonnes of lithium carbonate in 2025, at fourth-quarter cash operating costs of $5,618 per tonne and revenue of $92 million.
Fourth-quarter 2025 net income at Exar (Cauchari-Olaroz, 100% basis) was $31.2 million, yet Lithium Argentina recorded a 2025 net loss of $76.8 million, or $0.47 per share, driven by higher share of project losses, non-cash items and fair value changes. Cash and cash equivalents were $61.1 million as of December 31, 2025.
The company set 2026 production guidance at 35,000–40,000 tonnes of lithium carbonate and is advancing a 45,000 tpa Stage 2 expansion, plus the PPG project targeting 150,000 tpa across three phases. It completed an $85 million cash distribution from Cauchari-Olaroz and a $130 million six-year debt facility with Ganfeng to support refinancing and growth.
Lithium Argentina AG files its annual report outlining operations, risks and capital structure for the year ended December 31, 2025. The company had 162,406,904 registered common shares outstanding as of December 31, 2025 and operates the Cauchari-Olaroz lithium brine project and the PPG project in Argentina’s high-altitude Puna region.
The report highlights that Cauchari-Olaroz reached around 85% of its 40,000 tpa lithium carbonate nameplate capacity during 2025 and is pursuing a planned 45,000 tpa LCE expansion and potential adoption of Direct Lithium Extraction. Management discloses substantial project, technical and jurisdictional risks, including joint-venture governance with Ganfeng, climatic and reservoir uncertainties, and challenges in scaling new solvent-extraction technology at PPG.
The company notes significant indebtedness, including equity-settleable convertible notes and material third-party debt at Exar, and warns that its audited 2025 consolidated financial statements contain going concern disclosure. It also emphasizes exposure to Argentine macroeconomic instability, foreign exchange and capital controls, evolving climate and ESG regulation and potential impacts from geopolitical tensions around critical minerals.
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.
