BRUNSWICK EXPLORATION INTERSECTS UP TO 32.9 METERS OF LITHIUM BEARING PEGMATITE AT ANATACAU WEST

Brunswick Exploration Inc.'s Anatacau West maiden drill program has been completed and drilling has intersected multiple spodumene-bearing pegmatites. The Anatacau West project is located in the Eeyou Istchee-James Bay region of Quebec near Allkem's James Bay lithium project.

Killian Charles, president and chief executive officer of Brunswick, commented: "We are pleased that we have successfully identified significant spodumene mineralization in our maiden drilling campaign. Several lithium pegmatite dikes were intersected that remain open at depth and along strike to the south. While the Anatacau West project remains poorly explored and merits further work this summer, we remain focused on continuing our ambitious Canada-wide exploration campaign as we seek to delineate new prospective lithium-bearing pegmatites. This phase of drilling at Anatacau West is over and we now look forward to sharing more details on our next drill campaign at the Hearst project before the end of the month."

Anatacau West drill campaign overview

A total of 3,712 metres, representing 18 drill holes, were drilled at Anatacau West, targeting extensions of mineralized pegmatites found on Allkem's neighbouring claims. The drilling completed to date has successfully identified several spodumene-bearing pegmatites, two of which have a strike length of over 250 metres. Of the 18 drill holes, 17 drill holes intersected spodumene mineralization. All pegmatite intersections are above 200 metres depth; significant intercepts are listed herein, for which assays are pending.

Following summer prospecting, Brunswick will evaluate the appropriate next steps at Anatacau West. At this time, no further drilling is planned as the company wishes to fully evaluate the potential of its extensive portfolio in Quebec across the rest of Canada before proceeding with further drilling.

Following drilling completed to date, Brunswick believes the pegmatites are oriented north-northeast, are closely spaced in an en echelon pattern and dip steeply toward the west. The pegmatites are hosted in metasedimentary rocks similar to Allkem's James Bay lithium deposit. Potential exists for repetition of new pegmatites farther to the south and to the east.

Lithium mineralization in core was visually identified and consists predominantly of spodumene with minor lepidolite. Spodumene crystals are generally well formed, decimetric in scale (up to 10 centimetres) and have a white to grey colour.

The drill program initially consisted of a set of two fences, each spaced approximately 150 metres from each other. Five drill holes were completed in each fence (at approximately 75 to 100 m spacing). Two scissor holes were also drilled to confirm the geometry of the pegmatite dikes. Mineralization and pegmatite widths are their strongest in the middle of each fence reaching up to 32.9 m in width with visible mineralization of spodumene up to 20 per cent.

Another three holes targeted pegmatites that were identified through satellite imagery approximately three kilometres to the east. Strongly altered pegmatites were intercepted in two of the drill holes with traces of spodumene mineralization.
