Brunswick Exploration Drills 36 Meters at 1.51% and Continues to Extend the Mineralized Footprint of Mirage
Rhea-AI Summary
Brunswick Exploration (BRWXF) has reported promising results from its 2025 winter drilling campaign at the Mirage Project in Quebec's Eeyou Istchee-James Bay region. The company completed 24 drill holes, with significant findings including:
- A notable intersection of 36 meters at 1.51% Li2O in hole MR-24-102 within the Stacked Dyke area
- A new interval at MR-6 Dyke showing 1.32% Li2O over 28 meters in hole MR-24-101
- The MR-3, MR-6, and stacked dyke system now covers an area of over 1,000 meters by 450 meters
The drilling campaign focused on extending the mineralized Stacked Dyke area, with assays still pending for 16 holes. The Mirage Project, comprising 427 claims, is located 40 kilometers south of the Trans-Taiga Highway and 34 kilometers northeast of Winsome Resources' Adina Project.

MONTREAL, April 24, 2025 (GLOBE NEWSWIRE) -- Brunswick Exploration Inc. (TSX-V: BRW, OTCQB: BRWXF; “BRW” or the “Company”) is pleased to report the first results from the 2025 Mirage winter drilling campaign where it drilled an additional twenty-four holes targeting extensions of known mineralized zones. The Mirage Project is located in the Eeyou Istchee-James Bay region of Quebec, approximately 40 kilometers south of the Trans-Taiga Road. This release focuses on the Central Zone including the MR-6, MR-3 dykes and Stacked Dyke area where BRW has continued to intersect wide and well mineralized intervals along strike and at depth.
Highlights include:
- Significant interval of 36 meters at
1.51% Li2O in hole MR-24-102 within the Stacked Dyke area extending mineralization to the south-east and where an additional 13 dykes measuring between 1.3 and 9.35 meters were intercepted in the same hole. - New interval at the MR-6 Dyke with
1.32% Li2O over 28 meters in hole MR-24-101 extending the dyke to the northwest. - The MR-3, MR-6 and staked dyke system can now be traced together into a major swarm of spodumene bearing pegmatites covering a surface area of over 1,000 meters by up to 450m.
- A total of 24 drill holes prioritizing near surfaces mineralization in the extension of the staked dyke area were completed during the winter. Assays are pending for a further 16 holes.
Mr. Killian Charles, President and CEO of BRW, commented: “To date, every drill campaign has demonstrated the significant exploration upside at Mirage and these first results from our winter 2025 campaign are no different. We have successfully extended the MR-6 pegmatite and continue to rapidly add considerable intercepts in the neighboring Stacked Dyke area. Interestingly, this high potential target area has continued to return multiple significant mineralized intercepts over the entirety of each drill hole and the Stacked Dyke area remains open in multiple directions.
Brunswick Exploration remains one of the most active lithium exploration companies globally and looks forward to releasing more drill results from Mirage and the restart of prospecting in Greenland. With its unique portfolio, the Company expects to have a milestone rich year.”
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 2025 winter 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.

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 AGAT laboratory in Val-d’Or. All sample preparation and analytical work was performed by AGAT by sodium peroxide fusion with ICP-OES and ICP-MS finish. 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
