PMET Resources completes Phase 2 caesium testwork with Koch Technology Solutions

PMET Resources Inc. has completed its Phase 2 bench-scale caesium testwork program in collaboration with Koch Technology Solutions (KTS), a division of Koch Inc. The program focused on pollucite concentrate from the Shaakichiuwaanaan Project, which contains a significant pollucite-hosted caesium pegmatite mineral resource.

The testwork results demonstrated a pathway to produce various high-purity caesium-based chemical products. KTS’s proprietary technology may simplify and reduce the costs associated with producing these products. The company plans to expand follow-up testwork to include a complete bench-scale proof-of-concept and the production of marketable samples.

Caesium and tantalum are expected to be co-products at the Shaakichiuwaanaan site, with potential revenue potentially offsetting lithium production costs. A Preliminary Economic Assessment is scheduled for Q4 2026 to provide the initial economic evaluation of the caesium credit.
