Mr. Athanasios Pythagoras reports

TOMBILL MINES LIMITED TO ADOPT SEMI-ANNUAL FINANCIAL REPORTING

Tombill Mines Ltd. intends to rely on the exemptions contained in Coordinated Blanket Order 51-933, Exemptions to Permit Semi-Annual Reporting for Certain Venture Issuers, adopted by the Canadian Securities Administrators on March 19, 2026, and in Ontario on Ontario Securities Commission Rule 51-507, Exemptions to Permit Semi-Annual Reporting of Certain Venture Issuers, to file interim financial reports and related management's discussion and analysis (MD&A) on a semi-annual rather than quarterly basis. This news release is being filed pursuant to CBO 51-933.

The company intends to discontinue filing interim financial statements, management's discussion and analysis, and related certifications for the reporting period ending July 31, 2026, and for subsequent applicable interim periods. Tombill will continue to comply with all timely disclosure and material change reporting obligations under applicable Canadian securities laws and the policies of the TSX Venture Exchange.

The company believes adoption of the semi-annual reporting exemption will reduce administrative burden and compliance costs, allowing management to focus additional time and resources on the company's business and strategic objectives while continuing to provide investors with material information on a timely basis.

About Tombill Mines Ltd.

Founded 1935 by Newmont Mining, and Tom Johnson and Bill Johnson, Tombill owns two of the 11 past-producing and producing mines in Geraldton gold district (population: 4,300, about 225 kilometres northeast of Thunder Bay). Within this optimal local and mining infrastructure, the company's assets comprise four royalty-free claim groups, occupying the middle of the Geraldton gold district. The Greenstone gold mine (founded May, 2024), which borders on the east boundary, is one of Canada's largest gold mines and mills by annual production. The company's assets comprise 74 royalty-free claims (57 fully owned patent claims, three fully owned with easements, nine fully owned patented mineral rights and five leases) covering 3,168 acres. Of these, the 58-claim Main group borders west of the Greenstone gold mine and straddles the Trans-Canada Highway; the five-claim Ellis group lies four kilometres south of the town of Geraldton and the original Tombill Old mine group of six claims sits 10 kilometres west-southwest of Geraldton.

The Tombill Old mine produced 68,737 gold ounces at a grade of 12.47 grams per tonne between 1938 and 1942 and 1955 in the southeast part of that claim group. The Talmora mine, located northeast on the Main group, was built in 1942, but saw only very minor production before closing in 1948 (1,406 gold ounces at 5.05 grams per tonne). From the Greenstone open pit to Key Lake, the Geraldton camp is approximately 15 kilometres in length over a defined corridor -- essentially along the Bankfield Tombill fault and Trans-Canada Highway -- housing multiple shallow and deep gold zones.
