Technical Work Restarted At South Mountain Mine

BOISE, ID - Thunder Mountain Gold, Inc. reported on the progress of its South Mountain Mine located in Owyhee County, Idaho. The Company has restarted technical work on its Project, with a primary focus on updating the Mineral Resource Estimate (MRE) and advancing toward a Preliminary Economic Assessment (PEA).

The restarted technical work will focus on updating the MRE to reflect recent exploration results, further defining the high-grade polymetallic mineralization of zinc, silver, gold, lead, and copper. Following the MRE update, Thunder Mountain Gold plans to initiate a PEA, evaluating the economic potential and development pathways for South Mountain.

Mineral Resource Estimate Update: The updated MRE will incorporate recent exploration results, enhancing the understanding of the deposit's scale and grade distribution. Preliminary Economic Assessment: Upon completing the MRE, THMG will focus on delivering a PEA to outline the economic feasibility of advancing South Mountain towards production readiness. Technical Studies: The Company is also conducting technical studies, including metallurgical testing and site optimization, to support the restarted development efforts. Additional Exploration: In cooperation with its geophysical consultant - Durango Geophysical Operations, the Company plans expansive geophysical and geochemical work on surrounding prospective ground, following up on copper porphyry targets previously identified.

A strategic partnership with Swiss-based MFD Investment Holdings SA ("MFD") has provided additional funding, contributing $1,000,000 in project-related expenditures as well as providing technical support for project development. This partnership adds additional financial strength in advancing South Mountain's technical and economic studies.

Eric T. Jones, President and CEO, said, "We remain committed to advancing South Mountain as a high-grade polymetallic project with significant resource expansion potential. The ongoing MRE update and subsequent PEA will provide a strong foundation for the project's future development. Our partnership with MFD has further enhanced our ability to execute key technical work."
