PMET, Koch Unit Advance Simplified Caesium Chemical Process

Montreal – September 22, 2026 -- PMET Resources Inc. has completed a Phase 2 bench-scale testwork program with Koch Technology Solutions (KTS) that demonstrates a simplified, more selective pathway to convert pollucite concentrate from its Shaakichiuwaanaan Project into high-purity caesium chemical products.

KTS process shows high selectivity, bypassing costly impurity-removal stages

The bench-scale program used approximately 6 kg of pollucite concentrate, assaying 12% Cs2O, produced via X-Ray Transmission ore sorting of drill core from the Vega Caesium Zone at the CV13 Pegmatite. Results confirmed the KTS proprietary flowsheet technology achieves high selectivity for caesium with a much-reduced impurity profile, potentially allowing much of the conventional impurity-removal stages to be skipped and lowering recovery costs into a final high-purity product.

PMET Collects 2.5 Tonnes of Caesium Ore, Targets Q4 Ore Sorting

Montreal – September 12, 2026 -- PMET Resources Inc. has collected more than 2.5 tonnes of pollucite pegmatite from the Vega Caesium Zone (CV13) at its Shaakichiuwaanaan Property in Quebec, advancing a bulk-sampling initiative called the BerryPick program aimed at feeding downstream caesium chemical testwork.

PMET deploys large-diameter coring to cut sampling costs and speed

The company used very large diameter drill core (~30 cm) drilled through a grid of shallow holes (under 60 cm deep) across the mineralized outcrop, avoiding costlier alternatives such as blasting or PQ coring (8.5 cm). Prior testwork had relied on smaller NQ (4.8 cm) and HQ (6.4 cm) core, which supported only initial-stage programs; the larger fragments better approximate blasted run-of-mine material after crushing, a requirement for feasibility-level data.
