Patriot Battery Metals Inc. (ASX:PMT) Announces World’s Largest Caesium Mineral Resource
Largest Caesium Resource Confirmed
Patriot Battery Metals Inc. (ASX: PMT) has announced the world’s largest pollucite-hosted caesium pegmatite mineral resource at its Shaakichiuwaanaan Project in Quebec. The maiden Mineral Resource Estimate (MRE) for the Rigel and Vega zones includes 163,000 tonnes at 10.25% Cs₂O and 530,000 tonnes at 2.61% Cs₂O, with a total contained caesium content of 30.5 kilotonnes indicated and 40.8 kilotonnes inferred.
Operational Progress and Future Plans
The company is evaluating options to incorporate the caesium opportunity as an additional saleable product into the project’s economic development, following the completion of the lithium-only Feasibility Study on the CV5 Pegmatite. Patriot remains on track to deliver a maiden Ore Reserve and Feasibility Study for lithium at the CV5 Spodumene Pegmatite in Q3 2025.
Executive Comments
Darren L. Smith, Executive and Vice President of Exploration, stated, “At Shaakichiuwaanaan, we have now defined the largest reported occurrence of pollucite in the world – by a significant margin. To find a pollucite-hosted caesium deposit of this scale and grade is exceptionally rare, with only three deposits globally known to have produced this extremely high-value critical and strategic mineral.”
Ken Brinsden, President, CEO, and Managing Director, added, “This is another feather in the cap of our technical team, led by Darren, with their hard work resulting in yet another world-class discovery at Shaakichiuwaanaan. What stands out is the sheer scale and grade of this caesium discovery, relative to anything that’s been found before globally.”
