Abitibi's B26 mineral resources up 124% since optioning

Executive Summary

• Abitibi Metals Corp. announced a 124% increase in total mineral resources at its B26 polymetallic project in Quebec's Abitibi greenstone belt, driven by successive drilling campaigns and revised commodity price assumptions.
• The updated estimate defines 13.0 million tonnes of indicated resources and 12.3 million tonnes of inferred resources, grading 2.1% and 2.2% CuEq respectively, bringing total defined resources to over 25 million tonnes.
• Mineralization remains open laterally and at depth, with a fully financed 40,000-metre Phase 4 drill program underway to continue through 2026.

Key Details

• Resource Growth: 124% increase in total mineral resources since the project was optioned in 2023.
• Indicated Resource: 13.0 Mt at 2.1% CuEq (1.2% Cu, 1.2% Zn, 0.44 g/t Au, 30.8 g/t Ag); tonnage increased 14% from the prior estimate.
• Inferred Resource: 12.3 Mt at 2.2% CuEq.
• Total Defined Resources: >25 Mt.
• Contained Metals (Indicated): ~340M lbs Cu, 332M lbs Zn, 184,000 oz Au, 12.8M oz Ag (equivalent to 595M lbs CuEq / 1.2M oz AuEq).
• Drilling Database: 356 drill holes totaling 172,164 metres (102 holes by Abitibi in 2024/2025; 191 holes by Soquem).
• Assay Data: 67,842 assays with an average sample length of 1.20 metres.
• Cut-off & Mining Scenario: Underground mining scenario with an in situ cut-off of $100/tonne based on long-term metal price assumptions and established processing recoveries.
• Price Impact: ~9% of the tonnage increase attributed to revised commodity price assumptions; the remainder driven by additional drilling and lateral/vertical extensions.
• Effective Date & Standards: Jan. 1, 2026; prepared in accordance with NI 43-101 and CIM standards.
• Metal Growth vs Prior Estimate: Copper +40%, Gold +22%, Silver +21%, Zinc +9%.
• Future Exploration: Fully financed 40,000-metre Phase 4 drill program, including a 15,000–20,000-metre winter campaign, expected to continue through 2026.
• Project Location: 7 km from the former Selbaie mine in Quebec’s Abitibi greenstone belt, providing access to existing infrastructure and skilled labour.
• Additional Portfolio Update (Beschefer Gold Project): Historical drilling identified four notable intercepts, including 55.63 g/t Au over 5.57m and 13.07 g/t Au over 8.75m across four modelled zones.
