XXIX Metal plans drilling at Thierry, Opemiska

Executive Summary

• XXIX Metal Corp. announces fully funded drill programs: up to 15,000 m at the Thierry K1 deposit and 5,000 m at the Cooke gold zone of Opemiska.
• The Thierry program aims to expand an inferred resource of 53.6 Mt @ 0.38% Cu (plus Ni, Au, Pt, Pd, Ag) by updating the geological model and targeting higher‑grade zones at depth.
• A Preliminary Economic Assessment for Opemiska is slated for October 2025, with Ausenco leading the study; drilling is expected to start in fall 2025.

Key Details

• Thierry – K1 Deposit
• Planned drill length: up to 15,000 m.
• Current inferred resource: 53.6 Mt @ 0.38% Cu, 0.10% Ni, 0.03 g/t Au, 0.05 g/t Pt, 0.14 g/t Pd, 1.8 g/t Ag.
• New consolidated geological model shows mineralization from surface to 400 m depth, strike length > 1.4 km, widths up to 260 m, and increasing Cu grades with depth.

• Model incorporates 15 previously excluded drill holes for a more complete geometry.

• Opemiska – Cooke Gold Zone

• Planned drill length: 5,000 m.
• Historical production (Cooke mine): 1.97 Mt @ 5.04 g/t Au, 0.66% Cu.

• Objective: expand and enhance the current Opemiska resource base.

• Preliminary Economic Assessment (PEA)

• Target completion: October 2025 for Opemiska.
• Study lead: Ausenco.

• Focus: prioritize high‑grade tonnes early in mine plan, potentially adding high‑grade gold to improve project IRR and overall returns.

• Funding

• Both drill programs are stated as fully financed, indicating no additional capital raising required at this stage.

• Qualified Person

• Technical information reviewed and approved by Denis McNichols, P.Geo., Vice‑President Exploration, in accordance with NI 43‑101.
