TSX.V: BRW 2#3We Need More Grassroot Lithium Exploration! brunswick bru exploration Lithium demand has skyrocketed over the last two years and shows no sign of slowing down: • • Decarbonization is real and leading to a dramatic rewriting of global metal demand. Investments in new and existing lithium battery plants continue to grow at an extremely rapid pace. • THERE IS NOT ENOUGH LITHIUM SUPPLY TO MEET THIS FORECASTED DEMAND BRW is the one of the very few public companies aggressively and systematically conducting large-scale grassroots exploration for hard rock lithium in Canada. • We are well financed with key shareholders supportive of our long-term exploration program to discover new lithium sources • We use state-of-the-art exploration technology, including pegmatite discrimination criteria, satellite imagery and portable XRF-LIBS multi-element geochemistry.

Only S-type pegmatites can evolve into economic LCT (lithium-cesium-tantalum) pegmatites. Many of the areas we staked were historically explored for gold or base metal. Pegmatites were ignored for decades. Three-phase approach to our exploration program: 1. 2. Compilation and target generation using state-of-the-art geological models and technology; Field work and prospecting to discriminate pegmatites and identify LCT targets; 3. Drilling of high priority targets. This is a continuous process. TSX.V: BRW#10We Are Building the Largest Grassroots Package In The World brunswick bru exploration Our aggressive exploration initiative has allowed BRW to amass a portfolio of hundreds of untested pegmatites across Canada. • ● · . • ● In Quebec's James Bay region alone, we have secured over 250 untested pegmatites measuring over 600 meters in strike length. We have hundreds more smaller scale targets in our portfolio. This is one of the largest untested land packages of S-type pegmatites in the world. BRW's grassroots exploration strategy is a numbers game. More S-type pegmatites means greater chances of making a world class LCT discovery. Field testing+elimination+new acquisitions is a highly efficient and continuous process that will lead to discovery. It is replicable in any jurisdiction we deem prospective. There is no parallel in base metal or precious metal exploration.

Brunswick Exploration is focused on discovering new hard-rock lithium resources across Canada.
