Power Metallic Reports High Grade Assays and Provides Summer Update

Executive Summary

• Power Metallic completed its summer drill program (34 holes, 17,250 m) and reported high‑grade intercepts, including 22.66 m @ 4.57% CuEq (including 6.05 m @ 9.70% CuEq) in Hole 020 and 28.0 m @ 4.28% CuEq (including 3.4 m @ 15.45% CuEq) in Hole 015.
• The Lion Zone extension hole PML‑25‑014 intersected 9.44 m @ 1.10% CuEq, and multiple in‑fill holes confirmed continuity of the zone with variable grades and thicknesses.
• Fall‑Winter program updates include expanded mining rights near the Lion discovery, a pending land bid, and plans to release a detailed drilling schedule by end‑October.

• Six exploration holes on VTEM anomalies completed; results pending.
• Fall‑Winter program to incorporate newly acquired land (post‑Hydro‑Quebec restriction lift) with detailed schedule expected by end‑Oct 2025.
• Qualified Person: Joseph Campbell, P.Geo, VP Exploration, reviewed and approved technical disclosure.

Notable Quotes

“We were very excited to get this ground… the lifting of the Hydro‑Quebec restriction will really benefit the project’s development.” – Terry Lynch, CEO, Power Metallic.
