Thunder Gold Files NI 43-101 Technical Report for the Tower Mountain Property Mineral Resource Estimate

Thunder Gold Corp. has completed a significant milestone by filing its NI 43-101 Technical Report for the Mineral Resource Estimate on the Tower Mountain Gold Property, marking a critical step in the project's development trajectory. The report, prepared by qualified persons from Micon International Limited and dated March 9, 2026, provides the technical foundation required for advancing this 100%-owned gold project located strategically near Thunder Bay, Ontario's transportation infrastructure.

The Tower Mountain property encompasses 2,500 hectares surrounding the largest exposed intrusive complex in the eastern Shebandowan Greenstone Belt, where gold mineralization is associated with altered rocks around the Tower Mountain Intrusive Complex. Historical drilling has demonstrated gold continuity extending over 500 metres from the intrusive contact along a 1,500-metre strike length and to depths exceeding 500 metres, indicating substantial scale potential for the deposit.

The strategic significance of this filing extends beyond the immediate technical validation, as Thunder Gold positions the project as an emerging gold system with the scale and consistency to support long-term open-pit operations. The company emphasizes cost advantages including industry-leading drilling costs, existing infrastructure proximity, and access to skilled local workforce, factors that could enhance project economics in the current mining landscape.

Looking forward, the company has identified that 75% of the intrusive complex perimeter remains underexplored despite showing identical geological, alteration, and geophysical characteristics to the established mineralized zones. This presents significant expansion potential that could materially enhance the resource base as the company advances toward feasibility studies and potential production decisions.
