Magna Mining Reports 17.9% Cu, 0.6% Ni and 28.1 g/t Pt + Pd + Au over 1.8 Metres in the 700 Footwall Copper Zone at McCreedy West Mine

Executive Summary

• Magna Mining released additional underground diamond drill results from the McCreedy West mine, highlighting several high‑grade copper–nickel‑PGE intersections within 150 m of surface in the footwall of the 700 Cu‑PGE Zone.
• Notable intercepts include 17.9 % Cu, 0.6 % Ni, 28.1 g/t Pt+Pd+Au over 1.8 m (hole MMW‑25‑119) and 10.5 % Cu, 8.3 % Ni, 42.6 g/t Pt+Pd+Au over 0.3 m (hole MMW‑25‑133).
• Management indicated the results support near‑term production planning, potential expansion of the 700 Zone in 2026, and justify continued narrow‑vein mining methods and new western access development later this year.

Key Details

• High‑grade intercepts (selected examples):
• MMW‑25‑119 – 17.9 % Cu, 0.6 % Ni, 28.1 g/t Pt+Pd+Au over 1.8 m.
• MMW‑25‑133 – 10.5 % Cu, 8.3 % Ni, 42.6 g/t Pt+Pd+Au over 0.3 m.
• MMW‑25‑118 – 4.9 % Cu, 1.0 % Ni, 2.9 g/t Pt+Pd+Au over 1.5 m; also 10.4 % Cu, 0.5 % Ni, 16.1 g/t Pt+Pd+Au over 0.9 m.
• Additional notable assays (selected):
• MMW‑25‑119 – 1.7 % Cu, 0.7 % Ni, 4.0 g/t Pt+Pd+Au over 10.5 m.
• MMW‑25‑118 – 1.5 % Cu, 0.4 % Ni, 1.3 g/t Pt+Pd+Au over 7.3 m.
• Program context: Two underground drills are operating; one continues infill/definition drilling for near‑ to mid‑term production, the second is expanding into previously inaccessible footwall targets. Development of a new western access platform on the 930 Level is on schedule, with drilling expected later in 2025.
• Strategic implication: High‑grade Cu‑Ni‑PGE veins could be mined selectively in 2026, providing “high‑margin ore” and expanding the 700 Zone both up‑dip and laterally (east/west). The western margin is identified as a priority target with potential linkage to the historic Hardy/Boundary deposit.

Notable Quotes

“The diamond drilling at the McCreedy West mine continues to yield excellent copper and precious metal grades… These narrow, massive sulphide veins … can be incorporated into our mine plan and provide an opportunity for selective mining of high margin ore in 2026.” – Mynyr Hoxha, VP Mines Geology.
