THUNDER GOLD ACKNOWLEDGES $215,000 IN FUNDING FROM ONTARIO JUNIOR EXPLORATION PROGRAM (OJEP)

Thunder Gold Corp. is acknowledging $215,000 in funding from the Ontario government's Junior Exploration Program (OJEP).

Stephen Lecce, Minister of Energy and Mines for Ontario, announced $10-million in funding for 68 early exploration mining companies, at the Norcat Underground Centre northwest of Sudbury on March 19, 2026. "The Ontario Junior Exploration Program has been at the heart of discovery about sort of reimagining what is possible by government providing that upfront investment to really catalyze private sector investment in the North," said Mr. Lecce.

"Ontario is leading the charge to secure the minerals that will power our economy and strengthen our sovereignty," said Mr. Lecce. "Through OJEP, we're backing companies like Thunder Gold Corp. to advance promising projects here at home -- unlocking resources, creating jobs, and building a more self-reliant and secure Canadian economy."

The funding will be used to support exploration activities at the company's 100-per-cent-owned Tower Mountain gold property, located in the Shebandowan greenstone belt approximately 40 kilometres west of Thunder Bay, Ont. Grant-supported work is anticipated to include geophysical and geochemical programs designed to further advance the company's understanding of the project and support exploration and technical evaluation.

"The Ontario Junior Exploration Program plays an important role in supporting mineral exploration across the province," said Wes Hanson, president and chief executive officer of Thunder Gold. "This funding supports continued exploration at Tower Mountain and complements our ongoing work on the project as we advance key technical milestones. I would like to thank Premier Ford and Minister Lecce for their ongoing commitment to support the mining industry."

Tower Mountain benefits from excellent infrastructure access, low exploration costs and district-scale gold potential. The project is the focus of the company's current exploration and development efforts, highlighted in its recent NI 43-101 mineral resource estimate by Micon International Ltd.

On Jan. 26, 2026, the company announced a mineral resource estimate for Tower Mountain as summarized in the table. The estimate was prepared by Micon International of Toronto, an independent engineering firm specializing in mineral resource and reserve estimation for a global client pool.

About the Tower Mountain Gold property

The 100-per-cent-owned Tower Mountain gold property is located adjacent to the Trans-Canada Highway, approximately 40 kilometres west of the international port city of Thunder Bay, Ont. The 2,500-hectare property surrounds the largest, exposed, intrusive complex in the eastern Shebandowan greenstone belt, where most known gold occurrences have been described as occurring either within, or proximal to, intrusive rocks. Gold at Tower Mountain is localized within extremely altered rocks surrounding the Tower Mountain intrusive complex, a multiphase, long-duration intrusive complex that control gold distribution on the property. Historical drilling has established anomalous gold extending out from the intrusive contact for over 500 metres along a 1,500-metre strike length, to depths of over 500 metres from surface. The remaining 75 per cent of the perimeter surrounding the intrusion shows identical geology, alteration and geophysical response, offering a compelling exploration opportunity.

About Thunder Gold Corp.

Thunder Gold is advancing the Tower Mountain project in Thunder Bay, Ont., an emerging gold system with the scale, consistency and quality to support a long-life, open-pit operation. Results from the company's disciplined drill programs have consistently reinforced confidence in the continuity and predictability of the discovery, while highlighting significant potential for expansion across multiple zones of the Tower Mountain intrusive complex. With industry-leading drilling costs, existing infrastructure and a skilled local work force, Tower Mountain represents a rare combination of size, scalability and cost-effective growth.
