• Process technology test works produce 96% lithium recovery
• High purity lithium chloride concentrate successfully produced
• Lycopodium engaged to progress Rincon 40MW energy infrastructure works

Argosy Minerals Limited (ASX: AGY) provides an update on the 12,000tpa Rincon Lithium Project, located in Salta Province, Argentina. The company continues to advance the overall key engineering and feasibility works phase, with strong progress achieved across key development workstreams. The process design program is nearing completion, and test works conducted to optimize and upgrade the chemical flowsheet have proved constructive, with the company's concentrated lithium brine successfully producing a high purity lithium chloride concentrate using the selected process technologies, with test work results confirming a lithium recovery of 96%. The optimized process flowsheet validation testing has advanced to continuous pilot plant scale operations in Argentina. Consistent with its strategy to enhance flexibility, reduce capital intensity and de-risk project and operational execution, the company is pursuing a two-stage product development pathway: 12ktpa Stage 1a - lithium chloride production of solid lithium chloride as an intermediate product at the Rincon site, and 12ktpa Stage 1b - conversion of solid lithium chloride into battery quality lithium carbonate or lithium hydroxide. The company has also engaged Lycopodium as Owner's Electrical Engineer to progress the 40MW energy infrastructure project from design into construction, which will provide a reliable 33kV connection from the 500kV Argentina National Grid to the Rincon site.
