Brunswick Exploration Launches Phase 2 Drilling at Anatacau Lithium Discovery in Quebec
Brunswick Exploration Starts Phase 2 Drilling at Anatacau Lithium

Brunswick Exploration Inc. (TSX-V: BRW, OTCQB: BRWXF; FRANKFURT:1XQ) has officially launched Phase 2 drilling at its Anatacau Main Project, located in the Eeyou-Istchee James Bay region of Quebec. This significant exploration effort aims to build upon the Anais lithium discovery, which previously yielded an impressive intercept of 120 meters at 1.31% Li₂O. The project is strategically positioned 22 kilometers east and along strike of Rio Tinto's Galaxy Project, as well as Brunswick's own Anatacau West Project, placing it within a proven lithium-bearing structural corridor with substantial growth potential.

Drilling Program Details

The Phase 2 drilling campaign is set to complete approximately 2,500 meters, consisting of 12 inclined holes averaging 200 meters each. The initial three holes are designed to aggressively expand the Anais showing, where mineralization has been intersected in all previous holes and remains open at depth and along strike in all directions. This expansion effort underscores the company's commitment to unlocking the full potential of this promising lithium asset.

Geological Insights and Expansion

The largest pegmatite observed at the Anais showing has now been extended to over 250 meters in strike length and to a vertical depth of 115 meters, with an apparent thickness of 47.2 meters at its widest point. The main pegmatite dyke is interpreted to be dipping 85 degrees to the West. Additionally, several other well-mineralized stacked pegmatite intervals were intercepted in all holes, indicating the potential for further dyke discoveries in the vicinity of the outcrop.

The mineralized dykes at Anatacau are controlled by a major northwest–southeast deformation corridor, exhibiting structural control highly comparable to those observed at the Galaxy deposit. This regional structure appears to form a continuous corridor linking the Galaxy and Anais lithium discoveries, highlighting the scale and opportunity of this emerging system. The following nine holes will test the deformation corridor to the East for additional mineralized pegmatites.

Company Leadership and Future Plans

Mr. Killian Charles, President and CEO of Brunswick Exploration, expressed enthusiasm for the 2026 exploration program, stating, "I am extremely pleased to begin our significant 2026 exploration program at Anatacau Main and the Anais discovery. The drilling released in November last year from Anatacau was among the highest grade and longest lithium intercept released globally in 2025. It speaks to a highly promising project and to Brunswick’s exciting portfolio which includes the Mirage project, our Greenlandic lithium asset, Nuuk Lithium and our new Saudi Arabian lithium portfolio."

Results from the drilling campaign are expected to be released as rapidly as possible in early Q2. Following the completion of drilling at Anatacau, Brunswick plans to initiate prospecting activities in Saudi Arabia and an exploration program at the Mirage project, further diversifying its lithium portfolio.
