On January 8, 2026, Brunswick Exploration Inc. announced a maiden, open-pit Mineral Inferred Resource Estimate (“MRE”) of 52.2 million tonnes (“Mt”) grading 1.08% Li2O and 131ppm Ta2O5 for its wholly owned Mirage Project located in the Eeyou Istchee Baie-James region of Quebec, Canada. The MRE was prepared in accordance with the National Instrument (“NI”) 43-101 standards by PLR Resource Inc. and Synectiq Inc.
Highlights include:
- Inferred resource of 52.2Mt at 1.08% Li2O and 131ppm Ta2O5 at a cut-off grade of 0.5% Li2OEq for total contained lithia in excess of 550,000 tonnes. This places Mirage among the largest undeveloped hard rock lithium resources in the Americas.
- Additional Exploration Target of 40Mt to 50Mt grading between 0.80% and 1.10% Li2O and 120ppm and 145ppm Ta2O5 indicating a significant opportunity for continued near-term growth at Mirage. The potential quantity and grade are conceptual in nature. There has been insufficient exploration to define a mineral resource and that it is uncertain if further exploration will result in the target being delineated as a mineral resource.
- The maiden resource and Exploration Target are confined to a core area measuring approximately 1.5 by 3.0 kilometers. Substantial exploration potential exists both across this area, as seen in the Exploration Target, and further along strike, throughout the rest of the property where lithium mineralization is observed up to 3.5km from the MRE area.
- Over 70% of the MRE is contained within five dykes found above a vertical depth of 150 meters from surface, all of which remain open in several directions.
- Metallurgical testwork demonstrates the potential for a dense media separation (DMS) only processing flowsheet, producing a high-quality concentrate.
- The maiden MRE and Exploration Target were estimated after only 23,626 meters of drilling and 62 channel samples, significantly less than its peer group and similar projects.
