Brunswick Exploration (TSX-V:BRW) has uncovered three new major dykes at the Mirage Project in Québec, Canada, after completing a drilling program aimed at extending the mineralised stacked dyke zone.
The new dykes, located between 200 and 500m northeast of MR-6, returned 33.2m @ 1.1% lithium oxide, 20m @ 1.3% lithium oxide, and 11m @ 1.2% lithium oxide.
CEO Killian Charles says these results highlight the exploration potential at Mirage.
“Brunswick Exploration remains one of the most compelling stories in the mining sector as we leverage the atypical combination of advanced exploration work at Mirage alongside an aggressive global lithium grassroot program which has no comparable peers,” Charles says.
“As we move toward a maiden resource estimate in late 2025, I am extremely proud of the work the BRW exploration team has achieved across its still growing pipeline of projects.”
During the 2025 Canadian winter program, the company discovered four new major dykes measuring between 10 and 25m. All of the dykes are located near surface and in the core of the project, which remain open in all directions.
Further metallurgical work will be completed to determine the viability of producing a tantalum by-product.
The Mirage Project, comprising 427 claims, is located in the Eeyou Istchee-James Bay region of Québec, Canada.
Brunswick Exploration is a Montreal-based mineral explorer focused on grassroots exploration for lithium in Canada.
According to the Canadian Government, Canada was ranked seventh globally for its lithium production in 2023, producing 520 tonnes — representing 0.4% of the world’s production.
Canada ranks sixth in the world for its lithium reserves, accounting for 3.4% of the global lithium reserves. Meanwhile, Australia held the second-largest proven reserves with 6.2 million tonnes, while Chile ranked the largest with 9.3 million tonnes.
The same year, Australia led global lithium production, with five of its mines contributing more than half of the world’s total output.
