PL3: Investor Presentation

Patagonia Lithium's investor presentation details a significant lithium resource at Formentera, totaling 551,400 tonnes LCE, though primarily in the Inferred category. Recent drilling at Formentera has yielded numerous high-grade lithium intercepts, with some reaching exceptional levels. Furthermore, pilot plant test work using Ekosolve DLE technology demonstrated a high 92.1% lithium extraction efficiency, and the company is also exploring rare earth elements and niobium in Brazil.

Lithium Argentina Announces Cauchari-Olaroz Stage 2 Scoping Study Results and Acceleration of Initial Phase of 10,000 tpa

Lithium Argentina announced positive results from a Scoping Study for its Cauchari-Olaroz Stage 2 Expansion Project in Jujuy Province, Argentina. The study outlines an additional 45,000 tpa lithium carbonate production, resulting in an after-tax NPV 8% of $3.1 billion and an IRR of 28.5% at a lithium carbonate price of $18,000/t. Concurrently, the company reported an updated Mineral Resource Estimate with a 42% increase in total Measured and Indicated LCE resources, now totaling 28.1 Mt LCE, and is accelerating an initial 10,000 tpa phase of the expansion.

PUR: 2026 Annual Report

Pursuit Minerals Limited reported a net profit for the year ended June 2026, driven by significant progress on its Rio Grande Sur Lithium Project. The company completed a Pre-Feasibility Study outlining a 5,000tpa lithium carbonate operation with strong economics, including a post-tax NPV of US$364 million and an IRR of 22.4%. The project's Mineral Resource Estimate was updated to 1.264Mt LCE (a 14% increase), and a Maiden Probable Ore Reserve of 125kt LCE was declared, supported by successful pilot plant production of high-purity lithium carbonate. However, the company noted a material uncertainty regarding its ability to continue as a going concern.
