PMET Achieves Over 97% Caesium Extraction from Pollucite Concentrate

PMET Resources Inc. has announced significant progress in extracting caesium (Cs) from pollucite concentrate. According to the company, bench-scale testing conducted by SGS Canada achieved over 97% caesium recovery using sulfuric acid. The program also successfully removed key impurities, such as aluminum, and identified an opportunity for rubidium by-product recovery.

The primary objective of the test program was to identify preliminary conditions for efficient caesium extraction and impurity profile characterization from pollucite concentrate from the Vega Zone at the Shaakichiuwaanaan project. This successful phase will lead to the development of high-purity caesium sulfate, carbonate, and formate, and potentially rubidium carbonate.

Concurrently, PMET is collaborating with Koch Technology Solutions to evaluate advanced processing pathways. Koch's proprietary process has demonstrated highly selective and efficient caesium recovery factors, opening new avenues for producing caesium-bearing chemicals.

PMET Resources holds one of the world's largest pollucite-hosted caesium mineral resources at its Shaakichiuwaanaan project. The resource comprises 0.69 Mt of indicated and 1.70 Mt of inferred resources. The company aims to leverage this strategic asset and generate value through caesium chemicals in partnership with others.
