Montreal, April 30, 2026 – Brunswick Exploration Inc. (TSX-V: BRW, OTCQB: BRWXF; FRANKFURT:1XQ) announced today that it has satisfied all work expenditures and share payments required to fully exercise its option agreement for the Anatacau Main and West projects. The company has now acquired a 90% interest in both projects and retains a right of first refusal on the remaining free carried 10% held by Electric Elements Mining Corp.
Drilling Campaign Results
The company recently completed a winter drill campaign at the Anatacau Main Project, where the Anais showing is located. This followed highly successful exploration work in 2025. Multiple large, well-mineralized pegmatites have been identified in drill core, and several holes still have pending assays that will be released in the coming weeks.
Mineralized Highlights
Key results from drilling programs at Anatacau Main include hole AN-25-04 with 0.72% Li2O over 11.8 meters, and hole AN-25-05 with 1.31% Li2O over 120.7 meters. Hole AN-26-07 returned 1.52% Li2O over 6.9 meters and 1.02% Li2O over 167.9 meters. The true thickness of the Anais dyke is estimated at approximately 60%.
Exploration Targets
Recent compilation work has identified several high-priority targets across the project. Between two and five kilometers south of the Anais showing, three unverified spodumene showings were identified, significantly expanding the exploration potential. Further south, over 16 highly fractionated pegmatites with favorable K/Rb ratios were identified within the Pontax trend, neighboring two potential spodumene showings controlled by BRW.
Anatacau West Project
This project is immediately contiguous to Rio Tinto’s James Bay Lithium Project. Drilling has intercepted at least two large spodumene-bearing pegmatites within 250 meters of mineralized pegmatites on Rio Tinto’s project, sharing the same orientation and strike. Drilling has focused on near-surface mineralization, with pegmatites tested to a maximum vertical depth of 137 meters, remaining open at depth. Till work in 2024 outlined significant potential for repetition of new pegmatites to the south and east.
