PMET reports 97%-98% caesium extraction from pollucite concentrate in bench tests
  • Pmet Resources reported bench-scale tests extracting 97%-98% caesium from 12% Cs2O pollucite concentrate using sulphuric acid leaching.
  • Work advanced caesium processing options for the Shaakichiuwaanaan project, targeting value-added caesium chemicals from on-site pollucite concentrates.
  • Impurity removal tests cut aluminum and sulphur with negligible caesium losses; a potential rubidium by-product stream was identified.
  • Next test phase aims to produce gram-scale high-purity caesium salts; results expected in Q4 2026.
  • A project-wide PEA covering lithium, caesium, tantalum is scheduled for Q4 2026 alongside the CV5 lithium-only feasibility study.
