THUNDER GOLD PURCHASES FREEHOLD PATENT AT TOWER MOUNTAIN PROPERTY AND COMPLETES SALE OF SEAGULL LAKE PROPERTY

Thunder Gold Corp. has purchased 100-per-cent ownership of a freehold patent (the Kons patent), within the current boundary of the company's flagship Tower Mountain property in the Shebandowan greenstone belt, 40 kilometres west of the port city of Thunder Bay, Ont.

On May 8, 2026, the company acquired 100 per cent of the surface and mineral rights associated with the 31-hectare Kons Patent, within the Tower Mountain claim boundary. The company acquired the patent in exchange for a one-time cash payment of $50,000 (U.S.) and a one-time share issuance of 700,000 common shares of Thunder Gold. No legacy royalties are associated with the patent and no royalty was retained by the vendors.

The company also announces that Rift Mineral Inc., a private company, has earned a 100-per-cent interest in the Seagull Lake property located in the Leckie Lake area of Ontario, by paying the company $75,000.00 in cash and issuing 15.99 million Class A common shares of Rift. The company shall retain a 1.0-per-cent NSR (net smelter returns) royalty on the claims optioned to Rift, which can be purchased at any time for $1-million.

Wes Hanson PGeo, president and chief executive officer, states: "The Kons patent increases our surface rights within the existing property boundary, adds exploration potential and simplifies exploration access to the eastern TMIC contact. The acquisition will reduce access costs to the northeastern and eastern TMIC boundary where strong magnetic lows remain untested. All known mineralization surrounding the TMIC is coincident with strong magnetic lows observed at the western TMIC contact as well as at the P-target along the eastern TMIC contact. The remaining magnetic lows surrounding the TMIC are untested and represent a compelling exploration target as does the strong, linear magnetic low observed in the recently optioned Electra property to the west.

"Completing the Seagull Lake transaction with Rift Minerals allows us to continue focusing on advancing our flagship Tower Mountain property west of Thunder Bay, Ont. Rift has identified an exciting exploration concept at Seagull Lake, focused on natural pressurized gas that may include hydrogen and/or helium, in addition to the demonstrated platinum group element mineralization identified by historical drill holes. As a large shareholder, we wish them continued success with their ongoing exploration, currently being funded by Anteros Metals (CSE: ANT)."

The company also advises that the board of directors has approved the grant of one million options at a strike price of 15 cents for an 18-month term to a director of the company.

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 7,000-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.
