Brunswick Exploration Once More Outlines a New, Major Dyke at Mirage

MONTREAL, June 10, 2025 (GLOBE NEWSWIRE) -- Brunswick Exploration Inc. (TSX-V: BRW, OTCQB: BRWXF; “BRW” or the “Company”) is pleased to report a further six drill results from the Winter 2025 program at its Mirage Project. The Mirage Project is located in the Eeyou Istchee-James Bay region of Quebec, approximately 40 kilometres south of the Trans-Taïga Road. This press release focuses primarily on drilling completed north and east of the MR-6 dyke and, in the neighboring, “Stacked Dyke” area, where BRW continues to intersect dozens of well-mineralized spodumene-bearing pegmatites.

Highlights include:

• A newly discovered dyke located approximately 250 metres northeast of MR-6, which returned 29.25 metres at 1.19% Li₂O in hole MR-25-115 and it remains open in all directions.
• The “Stacked Dyke” area has been extended 150 m to the northeast, with hole MR-25-106 intercepting 1.01% Li₂O over 17.4 metres. The area continues to show significant potential and widespread mineralization over the entire length of the drill holes.

Mr. Killian Charles, President and CEO of BRW, commented: “Every drill campaign has underscored the potential of the Mirage project. As we begin to step out from the core area of interest, we continue to intersect new, significant, well-mineralized pegmatites, all located near surface and this release is no different. We have again extended both the footprint of the Stacked Dyke area and found new sub-parallel mineralization adjacent to MR-6. We believe the forthcoming resource estimate, expected in late 2025, will position Mirage as one of the most important lithium projects in the province of Quebec.

Looking further ahead, we expect to have news related to our Greenlandic summer program shortly and look forward to the start of drilling at our Anatacau project in late Q3.”

Mirage Project Drilling Overview

The Mirage Project comprises 427 claims located roughly 40 kilometers south of the Trans-Taiga Highway in Quebec’s James Bay region and 34 kilometers northeast of Winsome Resources’ Adina Project.

The drilling campaign focused on extending the mineralized Stacked Dyke area to the northeast. Highlights discussed in this release are shown in Table 1 and Figure 1. Collars are shown in Table 2.
