BRUNSWICK EXPLORATION COMPLETES OPTION AGREEMENT FOR ANATACAU MAIN AND WEST

Brunswick Exploration Inc. has completed all required work expenditures and share payments to fully exercise its option agreement for the Anatacau Main and West projects (see press release dated Nov. 28, 2022). Brunswick Exploration has now acquired a 90-per-cent interest in both projects and retains a right of first refusal (ROFR) on the remaining free carried 10 per cent held by Electric Elements Mining Corp.

Anatacau Main -- Anais

As a reminder, the company recently completed a winter drill campaign at the Anatacau Main project, where the Anais showing is located, following highly successful exploration work in 2025. Multiple large and well-mineralized pegmatites have been identified in drill core and several holes still have pending assays, which will be released in the coming weeks.

Anatacau Main -- exploration targets

Recent compilation work by the company has identified several high-priority targets across the rest of this project (see press release dated Feb. 19, 2026). Between two and five kilometres south of the Anais showing, three unverified spodumene showings were identified through compilation work. These showings significantly expand the exploration potential surrounding the Anais discovery.

Farther south on the project, the company has identified over 16 highly fractionated pegmatites with highly favourable potassium/rubidium ratios and mineralogy within the Pontax trend within over 90 pegmatite outcrops. These high-priority targets neighbour two potential spodumene showings controlled by Brunswick Exploration.

Anatacau West project

This project is immediately contiguous to Rio Tinto's James Bay lithium project. Following drilling completed to date, Brunswick Exploration has intercepted at least two large spodumene-bearing pegmatites within 250 metres of mineralized pegmatites on Rio Tinto's project and sharing the same orientation and strike (see press release dated May 24 and July 20, 2023). Drilling has initially focused on near-surface mineralization, with the pegmatites only being drill tested to a maximum vertical depth of 137 metres. They remain open at depth.

Till work completed in 2024 also outlined significant potential for repetition of new pegmatites farther to the south and to the east of the drilled pegmatites where several high values of spodumene grain count were reported (see press release dated Oct. 17, 2024).
