Brunswick Exploration starts Anatacau phase 2 drilling

Executive Summary

• Brunswick Exploration Inc. has launched Phase 2 drilling at its Anatacau Main project in Quebec, aiming to expand the Anais lithium discovery following a significant prior intercept of 120 metres at 1.31% Li2O.
• The new program consists of approximately 2,500 metres across 12 inclined holes, with the first three targeting the expansion of the Anais showing and the remaining nine testing the regional deformation corridor to the east.
• The company anticipates releasing results from this campaign in early Q2 2026, while also planning to begin prospecting in Saudi Arabia and exploration at its Mirage project in Greenland.

Key Details

• Drill Program Scope: Approximately 2,500 metres total, consisting of 12 inclined holes averaging 200 metres each.
• Previous Intercepts: The program follows a release from November 2025 featuring an intercept of 120 metres at 1.31% Li2O, described as among the highest grade and longest lithium intercepts globally in 2025.
• Geological Context:
  • The largest pegmatite at the Anais showing has been extended to over 250 metres in strike length and 115 metres vertical depth, with an apparent thickness of 47.2 metres at its widest point.
  • The main pegmatite dike dips 85 degrees to the west.
  • Mineralization is controlled by a major northwest-southeast (NNW-SSE) deformation corridor, structurally comparable to Rio Tinto's Galaxy project.
  • This structure forms a continuous corridor linking the Galaxy and Anais discoveries.
• Hole Objectives:
  • Holes 1-3: Aggressively expand the Anais showing (mineralization intersected in all previous holes, open at depth and along strike).
  • Holes 4-12: Test the deformation corridor to the east for further mineralized pegmatites.
• Future Plans: Following Anatacau drilling, the company expects to begin prospecting in Saudi Arabia and an exploration program at the Mirage project in Greenland.
• Results Timeline: Expected to be released as rapidly as possible in early Q2 2026.
• Qualified Person: Francois Goulet, Manager, Quebec, Professional Geologist.

Notable Quotes

• "I am extremely pleased to begin our significant 2026 exploration program at Anatacau Main and the Anais discovery. The drilling released in November last year from Anatacau was among the highest grade and longest lithium intercept released globally in 2025. It speaks to a highly promising project and to Brunswick's exciting portfolio which includes the Mirage project, our Greenlandic lithium asset, Nuuk Lithium and our new Saudi Arabian lithium portfolio." — Killian Charles, President and CEO
