Brunswick Exploration Inc. (TSX-V: BRW, OTCQB: BRWXF; FRANKFURT:1XQ) has announced additional results from its 2026 winter drilling campaign at the Anatacau Main Project, located in the Eeyou Istchee-James Bay region of Quebec. The company continues to intersect multiple new, large, and well-mineralized pegmatites to the east of the main Anais pegmatite.
Drilling Highlights
Drill hole AN-26-08 returned 1.10% Li2O over 17.7 meters within a larger package of continuous lithium mineralization spanning 123 meters at 0.72% Li2O. This intercept is among the highest-grade and longest cesium intervals reported in the James Bay region, with values up to 11.8 meters at 1.84% Cs2O.
The mineralized pegmatite zone, hosted within a structural corridor that includes the Anais pegmatite, now extends over 500 meters to the east and remains open. All newly reported pegmatites are open in all directions.
CEO Commentary
Mr. Killian Charles, President and CEO of BRW, stated: “We are starting to define a major system at Anatacau Main. After demonstrating significant mineralization at Anais, our exploration holes to the east have provided a first glimpse of the project’s potential as we continue to intercept multiple lithium-rich pegmatites. The strength of the mineralized fluids that formed these pegmatites is striking. Drilling has encountered significant and pervasive lithium mineralization in the host rock surrounding the pegmatites, indicating a well-formed system with further exploration upside.”
He added: “Almost all pegmatites have returned very high cesium values, indicating potential for additional payable minerals at Anatacau. Metallurgical testwork will be initiated promptly to evaluate cesium recoverability. This combination of large pegmatites enriched in both lithium and cesium compares favorably to neighboring projects.”
