Brunswick grows Anatacau’s pegmatite dyke system footprint

Brunswick Exploration (TSX-V:BRW) has increased the Anais strike extent to more than 350m wide and 600m long, after receiving the final assays from a drilling campaign at the Anatacau Main Project in Canada.

The mineral explorer says the results continue to highlight the “excellent” continuity of the Anais Main dyke, with step-out drilling intersecting multiple large, well-mineralised pegmatites. Hole AN-26-12 returned 27.4m @ 1.13% lithium oxide.

CEO Killian Charles says the company continues to grow the footprint of the pegmatite dyke system, with several intervals occurring over substantial widths.

“We now strongly believe that Anatacau is starting to show the same potential as our Mirage Project,” Charles says.

“This unique combination of two highly promising projects demonstrates Brunswick Exploration’s ability to continue to make impactful discoveries across its portfolio. We look forward to returning to Anatacau in late Q3 2026, following the completion of our forthcoming drill campaign at Mirage.”

The Anais Main dyke, which remains open in all directions, is interpreted to be gently folded, oriented north-south to northeast-southwest. The surrounding several mineralised dykes are interpreted to be stacked, subparallel, and steeply dipping towards the west. All of these dykes are hosted within the same structural corridor that hosts Rio Tinto’s (ASX:RIO) Galaxy Project.

Brunswick Exploration is a Montreal-based explorer focused on grassroots exploration for lithium and critical minerals.
