BRUNSWICK EXPLORATION DRILLS 93.45 METERS AT 1.55% LI2O AT MR-6

Brunswick Exploration Inc. has released more significant results from the Mirage winter drilling campaign. 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 and well mineralized intervals within the MR-6 dike and its vicinity, where it remains open in all directions.

Highlights include:

• Best interval to date at Mirage with 1.55 per cent Li2O over 93.45 metres in drill hole MR-24-62 starting at surface and which extends the flat dipping MR-6 dike a further 80 metres to the south-west.
• The MR-6 dike was also extended 135 metres to the north of MR-24-62 where BRW intersected 1.05 per cent Li2O over 34.05 metres in drill hole MR-24-65.
  • MR-6 has now been drill traced over 220 metres of strike extent with true thickness varying from 25 metres and up to 70 metres. The dike remains open in multiple directions with the strongest potential to the northeast and southwest.
• New MR-8 dike confirmed in the North zone with 1.27 per cent Li2O over 18.6 metres in drill hole MR-24-43 and 1.42 per cent Li2O over 11.5 metres in drill hole MR-24-55.
• New exploration drill hole located approximately 800 metres northeast of MR-6 intersected anomalous lithium values in drill hole MR-24-53 within a zone of stacked dikes. These intercepts continue to extend the central corridor of prospective dikes towards a spodumene bearing outcrop located 3.5 kilometers to the northeast, that has yet to be drill tested.
• A total of 26 drills holes results were received to date and 9 drills holes results style pending.

Mr. Killian Charles, President and CEO of BRW, commented: "With this latest set of results, MR-6 is rapidly becoming a top priority for Brunswick Exploration and will be the core focus of our next drill campaign. This is another very significant intercept which begins at surface and adds to the prior results of 58 metres at 1.59 per cent Li2O and 37 metres at 1.80 per cent Li2O. all starting from surface as well. Our understanding of the Mirage project has grown tremendously over the last six months and we are extremely excited to announce our future plans for the project over the forthcoming weeks and months as we continue to see important exploration potential across the project and outside the drill program area."

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. At Mirage, a spodumene-bearing pegmatite boulder field extends over 3.0 kilometers in a northeast direction and several dozen well-mineralized pegmatite outcrops have been observed along a 2.5 kilometers-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 dikes were intercepted, predominantly in MR-3 and MR-6. MR-6 is interpreted to be a large, thick, sub-horizontal dike with a higher-grade core with potential evidence of zonation to the northwest. Latest results confirm a thickening of the MR-6 dike to the southwest in MR-24-62 where drilling intercepted 93.45 metres at 1.55 per cent Li2O. This new hole significantly extends MR-6 to the southwest where the dike remains open. Moreover, BRW believes there is extensive potential to expand the MR-6 dike to the northeast where it also remains open. The higher-grade core which is generally oriented southwest-northeast was extended northwest of MR-24-62 with 34.05 metres at 1.05 per cent Li2O. The true thickness varys between 75 per cent and 95 per cent of intersected intervals. This core is defined by coarser and more prevalent spodumene mineralization and is thicker than other portions of the dike. Interestingly, a fence of holes continued to intersect the MR-6 dike up to 350 metres north of MR-24-62 where it remains open and the results are still pending (see Figure 3). In this region, the MR-6 dike appears to be more heterogenous with changing mineralization and highly variable spodumene concentration. MR-24-64 appears to be at the boundary of this new zone of the MR-6 dike and outside of the high-grade core. Spodumene mineralization is observed in MR-24-66 indicating the possibility of economic grades outside of the core.

There is potential to extend MR-6 350 metres to the west where it remains open towards the MR-3 dike. The MR-3 dike demonstrates significant apparent thicknesses of up to 50.6 metres at 1.06 per cent Li2O (See December 4, 2023 press release) in core with a moderate dip of 50 degrees towards the south with true thickness estimated at 95 per cent in all reported holes. MR-3 is oriented NE and reaches the surface where it can be traced continuously for more than 400 metres of strike with consistent thickness of 40 metres.

Potential to extend Central Zone 800 metres to the east where MR-24-53 intersected the volcanic-sedimentary contact to test a similar geological context as the MR-4 dike in the South Zone. Drill hole MR-24-53 returned 0.33 per cent Li2O over 23 metres within evidence of dike stacking. Although this intercept is not related to the MR-4 dike (located 2 km to the southwest), the drillhole highlights the lithium potential of the lithological contact throughout the project and further to the northeast.

The North Zone is located on the north limb of a regional fold, where a newly drilled dike, MR-8, was extended over 250 metres in strike (See figure 4 and 5) with 1.27 per cent Li2O over 18.6 metres in drill hole MR-24-43 and 1.42 per cent Li2O over 11.5 metres in drill hole MR-24-55. The dike remains open to the southwest and to the northeast with 0.84 per cent Li2O over 6.5 metres in drill hole MR-24-57 (See April 25, 2024 press release).

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 1-meter intervals to ensure representativity. Samples were bagged; duplicated on one-fourth 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 metres. Host basalts adjacent to the dikes may grade up to 0.3 per cent Li2O but were excluded from the reported intersections.
