ABITIBI METALS ANNOUNCES FILING OF NI 43-101 TECHNICAL REPORT FOR THE B26 DEPOSIT

Abitibi Metals Corp. has filed a National Instrument 43-101 technical report dated effective Jan. 1, 2026, entitled "NI 43-101 Technical Report on the Updated Mineral Resource Estimate for the B26 Project, Quebec, Canada," by Yann Camus, PEng, of SGS Canada Inc. on SEDAR+. The technical report is with respect to the updated resource estimation on its B26 polymetallic deposit in Quebec, Canada. The technical report has been prepared in accordance with National Instrument 43-101, Standards of Disclosure for Mineral Projects. The classification of the mineral resources is consistent with the Canadian Institute of Mining, Metallurgy and Petroleum (CIM) definition standards (2014 CIM definitions).

Highlights:

• Indicated resources increased by 14 per cent to 13 million tonnes from 11.3 million tonnes:
  • Indicated resources now grade 1.2 per cent copper, 1.2 per cent zinc, 0.44 gram per tonne gold and 30.8 g/t silver, or 2.1 per cent copper equivalent or 2.8 g/t gold equivalent.
  • Indicated resources contain 340 million pounds Cu, 332 million pounds Zn, 184,000 ounces Au and 12.8 million ounces Ag, or 595 million pounds of CuEq or 1.2 million ounces AuEq.
• Inferred resources increased by 72 per cent to 12.3 million tonnes from 7.2 million tonnes:
  • Inferred resources now grade 1.6 per cent Cu, 0.16 per cent Zn, 0.68 g/t Au and 8.14 g/t Ag, or 2.2 per cent CuEq or 2.97 g/t AuEq.
  • Inferred resources contain 435 million pounds Cu, 43 million pounds Zn, 268,000 ounces Au and 3.2 million ounces Ag, or 599 million pounds of CuEq or 1.2 million ounces AuEq.
• Significant growth across all metals: Since the 2024 resource estimate, results were previously announced in Abitibi's news release dated Feb. 5, 2026.

The mineral resource estimate has been prepared in conformity with the CIM Estimation of Mineral Resource and Mineral Reserves Best Practices Guidelines (2019). The updated resource included within the technical report was previously announced in the company's news release dated Feb. 5, 2026.

The qualified person, as defined under NI 43-101, is Mr. Camus, who is independent of the company.

The B26 property, located seven kilometres southeast of the historical Selbaie mine, is approximately 170 kilometres north of the Horne smelter and 140 kilometres north-northwest of the city of Amos in Abitibi. On Nov. 15, 2023, the company entered into an option agreement on the B26 property to earn up to 80 per cent from Soquem Inc. (see news release dated Nov. 16, 2023). As of March 12, 2026, Abitibi Metals has successfully completed the second phase of the option agreement, securing the additional 30-per-cent undivided interest and increasing its ownership to 80 per cent. The company is now the majority owner and operator of the high-grade B26 polymetallic deposit, with Soquem retaining a 20-per cent participating interest under a joint venture framework.

Jonathon Deluce, chief executive officer of Abitibi, remarked: "The filing of the technical report marks another significant milestone for Abitibi Metals. This updated mineral resource estimate incorporates 35,543.8 metres of drilling completed across 40 holes, 16 wedges and one hole extension as part of our successful 2024 and 2025 phase 2 and phase 3 drill programs. With more than 25 million tonnes now defined across both resource categories -- representing a 124-per-cent increase since the project was optioned from Soquem -- B26 has crossed an important threshold of scale and continuity."

Mr. Deluce continued: "With mineralization remaining open laterally and at depth, and a fully funded 40,000-metre phase 4 drill program currently under way, B26 is well positioned to continue demonstrating a strong growth profile toward Selbaie-scale potential. We have applied conservative base-case commodity price assumptions in the mineral resource estimate, using gold at $2,500 (U.S.) per ounce, silver at $30 (U.S.) per ounce, copper at $4.50 (U.S.) per pound and zinc at $1.35 (U.S.) per pound. At current spot prices, the indicated CuEq grade increases to 2.59 per cent, with inferred resources at 2.55 per cent CuEq."

Mr. Camus of SGS Canada is the independent qualified person, as defined by NI 43-101, responsible for the technical information presented in this news release, including the verification of released data.
