Brunswick Exploration intercepts 202 m spodumene pegmatite at Anatacau Main

MONTREAL, Sept. 17, 2026 (GLOBE NEWSWIRE) -- Brunswick Exploration Inc. ( TSX-V: BRW , OTCQB: BRWXF ; FRANKFURT:1XQ ; “ BRW ” or the “ Company ”) is pleased to report the results of a drill hole that represents an exceptional and material expansion to the Anais dyke at the Anatacau Main Project, located 20 km east of Rio Tinto's Galaxy project, in the Eeyou Istchee James Bay region of Quebec. This hole is part of the 2026 summer drill campaign, which is still ongoing at the Anatacau Main Project.

Significant Highlights of Drill Hole AN-26-15:

The hole’s intercept of 202 metres of spodumene-bearing pegmatites containing, on average, an estimated 25% spodumene extends the Anais dyke to a vertical depth of 300 metres.

This represents the single largest pegmatitic intercept drilled by Brunswick Exploration across its portfolio and is one of the largest mineralized intercepts reported in the James Bay amongst lithium focused companies.

The Anais dyke remains open in all directions and is significantly expanded following this drill hole. At this time, BRW believes there is considerable potential to continue expanding this discovery.

The drill hole also encountered several other spodumene-bearing pegmatite intervals , separate from the 202-metre intercept, with widths of up to 21.3 metres , containing between 20–35% spodumene.

Assays are pending and will be released as quickly as possible.

The Anatacau Project is strategically located approximately 440km north of Matagami by road, whereas PMET Resources’ Shaakichiuwaanaan project is 840km away, and WhiteRock’s Banana project is 1,060km away.

Mr. Killian Charles, President and CEO of BRW, commented: “While it is atypical for us to release mineralized intervals without assays, we believe the size of this major interval and its implication for the Anatacau Main project is highly material to Brunswick
