Canada-based Power Metals is moving to make the Case Lake task successful north-eastern Ontario, adjacent to the borderline with Quebec. The project, which could participate accumulation successful the 2nd fractional of 2026, is positioning itself to go the world’s 4th large caesium mine.
During PDAC 2025, Mining Technology spoke with Power Metals CEO Haydn Daxter astir the caesium marketplace and the adjacent steps for the Case Lake project.
Caesium is listed arsenic a captious mineral by some the US and Canada. It is utilized chiefly (70%) arsenic a low-viscosity fluid to assistance power good pressures and trim friction during high-temperature good drilling for lipid and state exploration. Caesium besides has applications successful atomic clocks, star and artillery technology, catalysis and medicine.
“We cognize that 3,000 tonnes of [caesium] ore is the yearly consumption, which is not a large deal, but currently, determination is nary excavation that is producing immoderate accordant tonnage,” says Daxter.
To date, lone 3 high-grade caesium mines person operated globally: Bitika successful Zimbabwe, Sinclair successful Western Australia and Tanco successful Manitoba, Canda. China has had a “foothold” successful each of these done state-owned relation Sinomine.
The US Geological Survey reported “intermittent” caesium accumulation and processing from mined ore and stockpiles astatine the Tanco excavation successful 2024, on with immoderate estimated excavation accumulation successful China.
“Previously, the US, Canada [and] Australia were each buying their caesium from the Chinese market,” adds Daxter. However, helium notes geopolitical hostility arsenic good arsenic the tariff warfare betwixt the US and Canada and Mexico is making it challenging.
The latest drilling results from Power Metals' Case Lake project, announced successful February, bespeak that the task hosts high-grade deposits of caesium, tantalum and lithium (spodumene).
“Last year, we completed implicit 8,000m of exploration drilling… and we are presently moving connected a maiden mineral assets that volition beryllium retired by the extremity of the archetypal 4th [Q1],” Daxter says.
Power Metals is besides moving connected a preliminary economical appraisal (PEA) for Case Lake, which is owed retired successful Q2. Further exploration drilling is besides scheduled for aboriginal this year.
Winsome Resources owns a 19.6% involvement successful Power Metals, arsenic good arsenic the offtake rights for lithium, cesium and tantalum from the company's Case Lake project.
