BRUNSWICK EXPLORATION FILES MAIDEN MINERAL RESOURCE ESTIMATE NI43-101 TECHNICAL REPORT FOR MIRAGE PROJECT

Brunswick Exploration Inc. has achieved a significant milestone by filing its maiden NI 43-101 compliant mineral resource estimate for the Mirage Project in Quebec's James Bay region. The technical report, prepared by PLR Resource Inc. and Synectiq Inc., establishes an inferred resource of 52.2 million tonnes grading 1.08% Li2O and 131ppm Ta2O5, containing over 550,000 tonnes of lithia. This substantial resource positions Mirage among the largest undeveloped hard rock lithium deposits in the Americas.

The resource estimate demonstrates exceptional efficiency in defining mineralization, having been established with only 23,626 meters of drilling across 132 drill holes and four trenches. Over 70% of the resource is contained within five dykes located above 150 meters from surface, all remaining open in multiple directions. The company has identified an additional exploration target of 40-50 million tonnes grading between 0.80-1.10% Li2O, indicating significant near-term growth potential within the core 1.5 by 3.0 kilometer area.

The technical work supports a potential dense media separation processing flowsheet that could produce high-quality concentrate, suggesting favorable metallurgical characteristics. With lithium mineralization observed up to 3.5 kilometers from the resource area, the property demonstrates substantial exploration upside beyond the current resource boundaries.

This maiden resource estimate represents a critical advancement for Brunswick Exploration's lithium portfolio and reinforces Quebec's position as a strategic lithium jurisdiction. The combination of resource scale, exploration potential, and favorable metallurgy positions Mirage as a significant asset in North America's critical minerals landscape, particularly important given growing demand for battery materials in the energy transition.
