BRW Brunswick Exploration Inc

Brunswick Exploration Inc. (TSX-V: BRW, OTCQB: BRWXF; FRANKFURT: 1XQ; “BRW” or the “Company”) is pleased to report 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 kilometers south of the Trans-Taiga Road. This campaign focused on the Central Zone including the MR-6 and MR-3 dykes (see October 8, 2024 press release) and has continued to intersect wide and well-mineralized intervals on their extension and at depth.

Highlights include:

• 37 meters at 1.14% Li2O in hole MR-24-87 and 1.15% Li2O over 23 meters in hole MR-24-89 extending mineralization at MR-3 down dip where it remains open.
• New interval at the MR-6 Dyke with 1.74% Li2O over 19.7 meters in hole MR-24-84 and 0.93% Li2O over 13.5 meters in hole MR-24-75 extending the dyke to the northwest.
• New multiple intervals in the stacked dyke area east of MR-6 with 1.39% Li2O over 12.9 meters and 1.99% Li2O over 10 meters in hole MR-24-78, 1.32% Li2O over 16.1 meters in hole MR-24-80 and 1.61% Li2O over 9.9 meters 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 meters at 1.40% Li2O.

Mr. Killian Charles, President and CEO of BRW, commented: “Once more, our drilling continues to expand the known mineralized zones at Mirage both along strike and down-dip. I’m particularly pleased to see the wide, well-mineralized intercept in MR-3 where the dyke 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 50Mt within 50km 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 meters just at Mirage, outlined several new significant dykes and substantially expanded the near-surface MR-6 dyke. 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 kilometers south of the Trans-Taiga Highway in Quebec’s James Bay region and 34 kilometers northeast of Winsome Resources’ Adina Project.

The summer drilling campaign focused on extending the mineralized dykes identified during the last two drilling campaigns. Highlights discussed in this release are shown in Table 1 and Figure 1.

Figure 1: Central Zone of the Mirage Project

The holes MR-24-86, MR-24-87 and MR-24-89 extended the MR-3 dyke 150m to the South (Figure 2). MR-3 has been now drill traced over an area measuring over 250 meters by 250 meters as seen on Figure 2 with an average thickness of 25 meters. Identified at surface to the north, the dyke plunges to the South where it remains open with the last intercept at a depth of only 125 meters vertical.

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

Holes MR-24-75 and MR-24-84 expanded the MR-6 dyke 100 meters to the Southwest. MR-6 has been now drill traced over an area measuring over 350 meters by 350 meters with an average thickness of 30 meters with a core zone where the average thickness increases to 50 meters. MR-6 continues to be open to the Northwest from surfaces to 170 meters vertical (Figure 3).

Figure 3: Cross Sections B to B’

Holes MR-24-78, MR-24-81 and MR-24-85 were drilled in the stacked dyke 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 meters by 300 meters, this zone remains open to the North, East and South. More drilling is needed to improve the interpretation of the geometry of each dyke in this zone.

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 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 BRW 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 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% Li2O, with maximum internal dilution of 5 meters. Host basalts adjacent to the dykes may grade up to 0.3% Li2O but were excluded from the reported intersections.
