BRUNSWICK EXPLORATION DRILLS 58.1 METERS AT 1.59% LI2O STARTING FROM SURFACE AT MIRAGE

Brunswick Exploration Inc. has released the first assays from the Mirage winter drilling campaign, where it drilled an additional 35 holes. The Mirage project is located in the Eeyou Istchee/James Bay region of Quebec approximately 40 kilometres south from the Trans-Taiga Road. The winter drill campaign focused on the Central zone and has continued to intersect multiple wide, well-mineralized intervals on the MR-6 dike and its vicinity where it remains open in all directions.

Highlights include:

• Best interval to date at Mirage with 1.59 per cent Li2O over 58.1 metres in drill hole MR-23-49 starting at surface and which extends the flat-dipping MR-6 dike a further 80 metres to the south. Importantly, MR-6 remains open to all directions.
• Evidence of significant dike stacking with an intercept of 1.71 per cent Li2O over 31.6 metres, including 14.0 metres at 2.32 per cent Li2O in drill hole MR-23-60 at a vertical depth of 60 metres, located 300 metres east from MR-6.
• Several other significant near surface intercepts in drill MR-24-60 including 1.03 per cent Li2O over 18.4 metres at a vertical depth of 11 metres, and 0.93 per cent Li2O over 12 metres. To date, four major dikes have been intercepted in this hole and all remain open in every direction.
• A total of 35 drill holes prioritizing near surface mineralization were completed during the winter and assays are pending for a further 32 drill holes.

Mr. Killian Charles, President and CEO of BRW, commented: "The winter drilling reaffirms once more Mirage's position as one of the most exciting lithium discoveries in Quebec. Building upon the last discovery from our previous campaign in 2023, the MR-6 dike has proven to be an extremely prospective exploration target with significant potential as it remains open in all directions. On the basis of current and expected results from our winter campaign, we have immediately started preparations and planning for a summer drilling campaign at Mirage. Combined with our extensive grassroot exploration across Canada and Greenland, the forthcoming summer promises to be milestone-rich for Brunswick Exploration shareholders."

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 km northeast of Winsome Resources' Adina Project. On the project, a spodumene-bearing pegmatite boulder field extends over 3.0 kilometres in a northeast direction and several dozen well-mineralized pegmatite outcrops have been observed along a 2.5 kilometres-long trend further to the northeast. Both the extent of the outcrops and boulder train remain open in all directions (See August 21, 2023 press release).

The Central Zone sits on a synformal fold hinge axis, oriented east-northeast, where multiple wide high grade pegmatite dike were intercepted predominantly in MR-3 and MR-6. The sub-horizontal and near-surface MR-6 dike appears to become thicker to the southwest (see Figure 3). However, the width and strike extent remain to be fully tested with true thicknesses varying between 75% and 95%. Further drill holes will be released from MR-6 and it is expected to be a core part of future drilling campaigns at Mirage. The MR-3 dike, located 350 metres southeast of MR-6 in the Central Zone also demonstrates significant apparent thicknesses of up to 50.6 metres at 1.06 per cent Li2O (See December 4, 2023 press release) with a moderate dip at around 50 degrees towards the south with true thickness estimated at 95% in all reported holes. MR-3 is oriented NE and reaches the surface where it can be traced continuously for more than 400 metres with continuous thickness in excess of 40 metres.

The new discoveries in MR-24-60 also significantly extend the potential in the Central Zone another 300 metres to the northeast of MR-6. This area has seen very little exploration with only a single hole drilled to date and all pegmatites, including the four sizeable ones, remain open in all directions. These four pegmatites are near surface and demonstrate similar mineralogy to MR-6.

The North Zone is located on the north limb of the folding, where the MR-1 dike likely dips to the north and returned bonanza grade intervals of 24.5 m at 2.18 per cent Li2O and 25.8 m at 2.57 per cent Li2O (See December 4, 2023 press release). Located 500m northeast, MR-24-57 significantly extends the exploration potential in the North Zone with the discovery of a new dike that returned 0.84 per cent Li2O over 6.5 metres (see above) where it remains open in all directions.

QAQC

All drill core samples were collected under the supervision of BRW 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 1m intervals to ensure representativity. Samples were bagged; duplicated on one-quarter core splits; 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 BRW contractor facility to the ALS laboratory in Val-d'Or. All sample preparation and analytical work was performed by ALS by ICP-AES according to the ALS method ME-MS89L. All results passed the QA/QC 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 cutoff grade of 0.3 per cent Li2O, with maximum internal dilution of 5 metre. Host basalts adjacent to the dikes may grade up to 0.3 per cent Li2O but were excluded from the reported intersections.
