Abitibi Metals 150m Step-Out Extends B26 Western Copper-Gold Zone With 8.16% CuEq Over 3.2m Within 11.0m at 3.93% CuEq, Highlighting Significant Expansion Potential

Executive Summary

• Significant step‑out intercepts expand the high‑grade Western Copper‑Gold Zone (e.g., 3.2 m @ 8.16 % CuEq) and extend the Zinc‑Silver VMS zone to ~225 m depth, plus discovery of a new copper‑gold shoot ~300 m west of the model.
• Phase 3 drilling is 84 % complete (16,990 m of 20,000 m); the program remains fully funded through 2027 with a planned 20,000 m Phase 4 in 2026.
• The results are expected to materially increase the B26 mineral resource base (currently 11.3 Mt @ 2.13 % CuEq indicated and 7.2 Mt @ 2.21 % CuEq inferred).

Key Details

• Western Plunge Copper‑Gold Zone – Hole 1274‑25‑373W1: 3.2 m @ 8.16 % CuEq (6.26 % Cu, 2.21 g/t Au) within an 11.0 m @ 3.93 % CuEq interval.
• Zinc‑Silver VMS Zone – Hole 1274‑25‑371W1: 7.2 m @ 2.29 % CuEq (3.56 % Zn, 166.81 g/t Ag) within a 24.0 m @ 1.05 % CuEq interval.
• New Copper‑Gold Zone – Hole 1274‑25‑372: ~25 m of copper mineralization at ~550 m depth; best sub‑interval 0.9 % Cu & 0.9 g/t Au (1.7 % CuEq) over 3 m, located ~300 m west of the current block model.
• Additional high‑grade intercepts (selected):
• Hole 1274‑25‑371: 5.55 m @ 1.36 % CuEq (1.29 % Cu, 2.38 g/t Ag).
• Hole 1274‑25‑373W1: 3.2 m @ 8.16 % CuEq (6.26 % Cu, 2.21 g/t Au) – one of the highest grades reported to date.
• Phase 3 drilling status: 16,990 m completed; remaining ~3,010 m scheduled for completion by end‑Nov 2025.
• Funding: Program fully funded through 2027; Phase 4 (20,000 m) planned for 2026 to further expand the resource.
• Resource context: Current estimate – Indicated: 11.3 Mt @ 2.13 % CuEq (1.23 % Cu, 1.27 % Zn, 0.46 g/t Au, 31.9 g/t Ag); Inferred: 7.2 Mt @ 2.21 % CuEq (1.56 % Cu, 0.17 % Zn, 0.87 g/t Au, 7.4 g/t Ag).
• Assay methodology: Samples split and sent to AGAT Laboratories; fire‑assay for Au with gravimetric finish; four‑acid digestion for multi‑element analysis; CuEq calculated using $4.00/lb Cu, $1.50/lb Zn, $20/oz Ag, $2,500/oz Au (recovery factors applied).
• Qualified Person: Louis Gariépy, P.Eng., VP Exploration, reviewed and approved technical information per NI 43‑101.
