Abitibi Metals Delivers 124% Resource Growth at B26, Defining a High-Grade Copper-Gold System of Meaningful Scale

Executive Summary

• Abitibi Metals announced a 124% increase in total mineral resources at its B26 deposit, now totaling >25 Mt (13.0 Mt Indicated + 12.3 Mt Inferred) with an average grade of 2.1 % CuEq.
• Contained metal totals rose sharply: copper +40%, gold +22%, silver +21%, zinc +9%; the Indicated resource now holds ~340 M lbs Cu, 332 M lbs Zn, 184 k oz Au, and 12.8 M oz Ag (595 M lbs CuEq, 1.2 M oz AuEq).
• The company has launched a fully‑funded 40,000‑m Phase 4 drill program (≈15–20 k m winter campaign) to further expand the deposit through 2026.

Key Details

• Resource Expansion
• Indicated: 13.0 Mt @ 2.1 % CuEq (1.2 % Cu, 1.2 % Zn, 0.44 g/t Au, 30.8 g/t Ag) – up 14% in tonnage vs. prior estimate.
• Inferred: 12.3 Mt @ 2.2 % CuEq – new category added since last update.

• Total defined resources >25 Mt @ 2.1 % CuEq.

• Contained Metals (Indicated)

• Copper: ~340 M lbs (595 M lbs CuEq)
• Zinc: ~332 M lbs
• Gold: ~184 k oz (1.2 M oz AuEq)

• Silver: ~12.8 M oz

• Drilling Database

• 356 drill holes, 172,164 m total depth.
• Includes 102 holes drilled by Abitibi in 2024‑2025 and 191 historic holes from SOQUEM/Investissement Québec.

• 67,842 assays with average core length 1.20 m underpin the model.

• Assumptions & Cut‑off

• Underground mining scenario; US$100/t cut‑off based on long‑term metal price assumptions and processing recoveries.

• ~9% of tonnage increase driven by revised commodity price assumptions; remainder from new drilling and lateral/vertical extensions.

• Future Drilling Program

• Phase 4: 40,000 m total, fully funded.

• Winter campaign: ~15,000–20,000 m planned; continuation through 2026 to test open‑ended zones laterally and at depth.

• Strategic Context

• B26 sits 7 km from the former Selbaie mine within a well‑established mining district, offering infrastructure and skilled labor.
• The deposit now qualifies as a “cornerstone” VMS copper‑gold asset supporting Abitibi’s Québec portfolio strategy.

Notable Quotes

• Jonathon Deluce, CEO: “The updated resource demonstrates our ability to rapidly grow a high‑grade, polymetallic system while maintaining consistent grades—a key milestone that positions B26 as a cornerstone asset in the Abitibi Greenstone Belt.”
