Argosy Minerals made progress in its Rincon Lithium Project in Argentina's Lithium Triangle.
Argosy aims to increase ownership to 90% with the development of a 10,000 tpa operation.
The company has produced battery-quality lithium carbonate at its industrial scale pilot plant, selling 25 tonnes to Japan and South Korea customers.
Argosy Minerals plans to expand beyond 12,000 tpa and enter the USA with the Tonopah Lithium Project.
