Widest Caesium Drill Intercept to Date at the Helios Caesium Zone in Final Batch of 2025 Drill Results from Shaakichiuwaanaan
North America's critical-mineral powerhouse
The most recent news (March 18, 2026) reports the final assay results from the 2025 drilling campaign at the Shaakichiuwaanaan Property. Key highlights include the widest caesium (Cs2O) intercept to date at the Helios Caesium Zone (4.9 m at 3.65% Cs2O) and the discovery of a new mineralized lens north of the Vega Zone. This follows a series of high-grade lithium and caesium results reported throughout early 2026. The company has now completed 57,024 meters of drilling for the year and is transitioning into data interpretation to update geological models and Mineral Resource Estimates (MRE).
The most recent news is Routine - Positive. While the drill results are technically impressive (widest caesium intercept to date), they are incremental follow-ups to the major discoveries and high-grade intercepts already reported in January and February 2026. - In line with expectations: The market was already aware of the high-grade nature of the Vega and Helios zones. These results confirm continuity and scale but do not fundamentally alter the project's known potential. - Strategic Shift: The news reinforces the company's transition from a "lithium-only" story to a multi-commodity play. The successful production of marketable lithium hydroxide, tantalite, and pollucite (caesium) concentrates at bench-scale is a critical de-risking step. - Financial Context: This news follows the massive C$138 million financing closed in February 2026, which provides the "dry powder" necessary to integrate these co-products into the upcoming Feasibility Study (FS).
PMET Resources (formerly Patriot Battery Metals) owns 100% of the Shaakichiuwaanaan Project in the James Bay region of Quebec. It is the largest lithium pegmatite resource in the Americas. - Flagship: CV5 Pegmatite (84.3 Mt Probable Reserve at 1.26% Li2O). - Secondary: CV13 Pegmatite (Host to the world's largest pollucite-hosted caesium resource). - Infrastructure: Year-round road access and 14km from hydroelectric power.
