BRUNSWICK EXPLORATION DRILLS 37 METERS AT 1.14% EXTENDING THE MR-3 DYKE AT THE MIRAGE PROJECT

Brunswick Exploration Inc. has released the last results from the Mirage summer drilling campaign. The Mirage project is located in the Eeyou Istchee-James Bay region of Quebec, approximately 40 kilometres south of the Trans-Taiga Road. This campaign focused on the Central zone, including the MR-6 and MR-3 dikes (see Oct. 8, 2024, press release) and has continued to intersect wide and well-mineralized intervals on their extension and at depth.

Highlights include:

• 37 metres at 1.14 per cent Li2O (lithium oxide) in hole MR-24-87 and 1.15 per cent Li2O over 23 metres in hole MR-24-89, extending mineralization at MR-3 downdip, where it remains open;
• New interval at the MR-6 dike with 1.74 per cent Li2O over 19.7 metres in hole MR-24-84 and 0.93 per cent Li2O over 13.5 metres in hole MR-24-75, extending the dike to the northwest;
• New multiple intervals in the stacked dike area east of MR-6 with 1.39 per cent Li2O over 12.9 metres and 1.99 per cent Li2O over 10 metres in hole MR-24-78, 1.32 per cent Li2O over 16.1 metres in hole MR-24-80 and 1.61 per cent Li2O over 9.9 metres in hole MR-24-85;
• Hole MR-24-91, drilled for forthcoming metallurgical results, reaffirms the thick, near-surface continuous mineralization at MR-6 with 56 metres at 1.40 per cent Li2O.

Killian Charles, president and chief executive officer of Brunswick Exploration, commented: "Once more, our drilling continues to expand the known mineralized zones at Mirage both along strike and downdip. I'm particularly pleased to see the wide, well-mineralized intercept in MR-3 where the dike appears to thicken at depth. This is something observed across many well-mineralized lithium systems globally and Mirage is no different. Our primary objective at Mirage and across our portfolio is focused on defining a resource of at least 50 million tonnes within 50 kilometres from infrastructure and drilling to date continues to underscore this potential.

"While 2024 has been a challenging year for lithium markets, we have kept our focus on expanding Mirage and outlining new targets across our portfolio. We drilled approximately 12,000 metres just at Mirage, outlined several new significant dikes and substantially expanded the near-surface MR-6 dike. Outside of Mirage, we also made the first greenfield lithium discovery in Greenland.

"As we look to 2025, we will build upon these successes with a major winter drill program at Mirage, which will target new zones that have never been drilled before and launch one of the largest grassroot exploration program ever in Greenland."

Mirage project drilling overview

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

The summer drilling campaign focused on extending the mineralized dikes identified during the last two drilling campaigns. Highlights discussed in this release are shown in the attached table.

The holes MR-24-86, MR-24-87 and MR-24-89 extended the MR-3 dike 150 metres to the south. MR-3 has now been drill traced over an area measuring over 250 metres by 250 metres, with an average thickness of 25 metres. Identified at surface to the north, the dike plunges to the south, where it remains open with the last intercept at a depth of only 125 metres vertical.

Interestingly, hole MR-24-87 shows a significant thickening of the pegmatite, where it reaches an overall size of 58 metres downhole. This is associated with a larger core of higher-grade lithium mineralization highlighted in the intercept of 37.0 metres at 1.14 per cent Li2O.

Holes MR-24-75 and MR-24-84 expanded the MR-6 dike 100 metres to the southwest. MR-6 has been now drill traced over an area measuring over 350 metres by 350 metres with an average thickness of 30 metres with a core zone where the average thickness increases to 50 metres. MR-6 continues to be open to the northwest from surfaces to 170 metres vertical.

Holes MR-24-78, MR-24-81 and MR-24-85 were drilled in the stacked dike zone located immediately to the east of MR-6. These new holes continue to confirm the potential of this zone with multiple wide high-grade lithium mineralization. Contained within an envelope of 250 metres by 300 metres, this zone remains open to the north, east and south. More drilling is needed to improve the interpretation of the geometry of each dike in this zone.

Quality assurance/quality control

All drill core samples were collected under the supervision of Brunswick Exploration employees and contractors. The drill core was transported by helicopter and by truck from the drill platform to the core logging facility in Val d'Or. Each core was then logged, photographed, tagged and split by diamond saw before being sampled. All pegmatite intervals were sampled at approximately one-metre intervals to ensure representativity. Samples were bagged; duplicated on reject, blanks and certified reference materials for lithium were inserted every 20 samples. Samples were bagged and groups of samples were placed in larger bags, sealed with numbered tags, in order to maintain a chain of custody. The sample bags were transported from the Brunswick Exploration contractor facility to the ALS laboratory in Val d'Or. All sample preparation and analytical work was performed by ALS using ICP-AES according to the ALS method ME-MS89L. All results passed the quality assurance/quality control screening at the lab and all inserted standard and blanks returned results that were within acceptable limits. All reported drill intersections are calculated based on a lower cut-off grade of 0.3 per cent Li2O, with maximum internal dilution of five metres. Host basalts adjacent to the dikes may grade up to 0.3 per cent Li2O but were excluded from the reported intersections.
