May 28, 2026, 7:45 PM EDT. Argosy Minerals (ASX: AGY) achieved 99% lithium chloride purity and 94.4% lithium yield in pilot tests at its Rincon Lithium Project, validating key process technologies. These results reduce technical risks and support progression to the Definitive Feasibility Study (DFS), targeting a 12,000 tonnes per annum production capacity. Operational stability and improved system recovery over time were confirmed, underpinning robust process performance. The company's two-stage development strategy focuses first on producing crystallised lithium chloride, then converting it into battery-grade lithium carbonate or hydroxide. While the milestone de-risks the project, investors remain cautious about funding needs, scale-up execution risks, and Argentina's challenging economic environment, including currency volatility and hyperinflation.
