Mr. Wes Hanson reports

THUNDER GOLD ANNOUNCES PIERRE A.J. JULIEN, MBA, CIMF AS DIRECTOR

Thunder Gold Corp. has appointed Pierre A. J. Julien to the company's board of directors.

Mr. Julien is a senior executive with 40 years of mining industry leadership experience. He brings a proven management record across multiple areas of the mining industry including finance, talent acquisition, project development, project execution, technological innovation, plant operations, and mergers and acquisitions. This experience spans global mining projects of all scale throughout North and South America and Europe. He has been a key contributor to the industry through his leadership roles at both the Canadian Mineral Processors (CMP) Society where he served as chair and the Canadian Institute of Mines and Metallurgy (CIM) where he served as president. Mr. Julien has served as executive director and chair of DRA Americas Inc. since 2018, a role he has retired from earlier this year.

Mr. Julien was recently welcomed to the board of the Canadian Mining Hall of Fame earlier this year.

Wes Hanson, president and chief executive officer, states: "I am honoured to welcome Pierre as our newest director. We have many mutual friends in the industry, and this is the first time we have been able to collaborate on a project together. Pierre is one of the most well-respected professionals in the industry. His knowledge and experience with project financing, design, engineering, development, construction and operation will be invaluable as we continue to advance and derisk the Tower Mountain property. His leadership roles at DRA Americas and his contributions to the industry through his CMP and CIM will be hugely beneficial for our shareholders and stakeholders immediately and in the future. Pierre is a guy who gets things done, understands project risk, and brings a skill set and professional network capable of addressing any challenge. I look forward to working with him and the team as we continue moving Tower Mountain forward."

Mr. Julien states: "I'm thrilled to be joining Wes Hanson and the Thunder Gold team. I've personally known Wes for over 25 years and always been impressed with his no-nonsense approach, the quality of projects he's been involved with and the respect he's garnered from industry peers. The Tower Mountain property is shaping up to potentially become a generational gold asset that could compete with the largest in the country. What is not to like, highly consistent disseminated mineralization, 40.0 kilometres from Thunder Bay, Ont., low strip ratio, year-round access road, power lines and rail already at the property. In all my years, I've seen a lot of projects, some with similar grades, but very few with the infrastructure advantages offered by Tower Mountain."

About the Tower Mountain gold property

The 7,625-hectare, 100-per-cent-owned Tower Mountain property is beside the Trans-Canada highway, 40 kilometres west of Thunder Bay, Ont. (population 120,000). Gold mineralization occurs in variably brecciated and altered rocks surrounding the calc-alkalic Tower Mountain intrusive complex (TMIC). Drilling to date has established an initial mineral resource parallel to the western contact of the intrusion representing approximately 25 per cent of the TMIC halo.

The MRE has an effective date of Jan. 19, 2026. A technical report titled "NI 43-101 Technical Report for the 2026 Mineral Resource Estimate on the Tower Mountain Project, Ontario, Canada," is available on the company's website and on SEDAR+ under the company's issuer profile.

The report was prepared by Charley Murahwi, PGeo, FAusIMM; William Lewis, PGeo, Tudorel Ciuculescu, PGeo, and Richard Gowans, PEng, all of Micon International Ltd., Toronto, Ont., Canada. The report was prepared in accordance with National Instrument 43-101 -- Standards of Disclosure for Mineral Projects and CIM Definition Standards of Mineral Resources and Mineral Reserves.

The MRE is summarized as follows.

The remaining 75 per cent of the TMIC halo demonstrates similar geology, alteration and geophysical signatures, and is untested by drilling.

A second gold trend, identified in 2026, outcrops at surface and is continuously mineralized over a 100-metre width. This gold mineralization occurs within Timiskaming-type conglomerates that have been traced for over 5.0 kilometres along a southwest trend paralleling the Thunder Lake fault. The company believes both targets offer opportunities to materially increase the total resource through systematic drilling.
