BLUE MOON METALS COMPLETES FIRST BLAST ON NUSSIR ACCESS PORTAL AHEAD OF SCHEDULE

Blue Moon Metals Inc. has begun underground construction on the Nussir mine, completing the first blast on the access portal on June 12, 2025 (ahead of schedule).

Nussir's mining contractor, Leonhard Nilsen & Sonner AS, will extend the decline approximately 2,500 metres, providing a platform for further underground exploration. The exploration work to be completed over the next year will provide key engineering inputs and lead to a final investment decision in 2026.

Christian Kargl-Simard, Blue Moon's chief executive officer, stated, "This key milestone marks the start of the next chapter in the exciting Nussir story and brings us one step closer to putting this important critical-metals mine into operation, supplying Europe's copper needs."
