Elevated Lithium Recoveries from Organic Acid Leaching Compounds

Arcadia Minerals Ltd (ASX:AM7, DAX:8OH) (Arcadia), the diversified exploration company targeting a suite of projects aimed at Tantalum, Lithium, Nickel, Copper and Gold in Namibia, is pleased to announce positive lithium organic leach test results from its Bitterwasser lithium clay project.

Philip le Roux, CEO of Arcadia stated: “This result is a significant step for Arcadia towards possibly confirming the viability of extracting significant quantities of lithium from the Bitterwasser clays in an environmentally and economically compliant manner. The test results, combined with the potential of producing a lithium rich leachate from concentrates2 , holds the promise of confirming processing matrices with competitive capex and opex responses for any future analyses of economic and technical assessment, which Arcadia could undertake towards confirming the project viability. “

HIGHLIGHTS

• Pre-liminary leaching test work conducted at the University of Stellenbosch1 indicates that organic acids are suitable to extract lithium from the Bitterwasser clays
• Initial unoptimized test work indicates that one specific organic acid extracts up to 78% of the lithium
• Organic acids are generally regarded as being environmentally friendly and relatively cheap to produce and use, compared to inorganic acids such as Sulfuric and Hydrochloric Acid
• Full-scale test work program underway at the University of Stellenbosch to further optimise and potentially increase the leachability and recoveries
