Thunder Mountain Gold, Inc. Announces Field Work for the 2025 Exploration Season Has Begin at its South Mountain Mine Project in Owyhee County, Idaho Thunder Mountain Gold, Inc. announced that field work for the 2025 Exploration season has begun at its South Mountain Mine project in Owyhee County, Idaho. The intensive field exploration program is the first step in preparations for a planned drilling program later this season once targets are generated through interpretation of the geologic, geochemical and geophysical data through visualization of the data in the 3-D Leapfrog software. The Company has mobilized geologists, geophysicists and techs to conduct geological mapping, sampling, and advanced geophysical surveys across critical zones at South Mountain. These activities are designed to refine and expand target areas, while updating existing structural and stratigraphic models in advance of drilling. This phase of fieldwork includes: Comprehensive surface mapping and chip-channel sampling across key carbonate replacement deposits (CRD)_/skarn and porphyry-hosted zones. Drape Magnetic and Magnetotelluric (MT) surveys to delineate continuity of high-grade lenses and deep-seated targets. Ground truthing and follow-up on historical IP/geochemical anomalies to advance drill target confidence. Georeferencing historic data from Anaconda Mining and others into the model. Next steps: Following the completion of this phase of field program, Thunder Mountain plans to interpret the data and generate drill targets for fourth quarter drilling. Permitting for drilling is in progress, leveraging existing approvals for underground and surface exploration. Regarding Thunder Mountain Gold Inc. Thunder Mountain Gold Inc., a junior exploration company founded in 1935, owns interests in base and precious metals projects in the western U.S. The Company's principal asset is The South Mountain Mine, a historic former Anaconda Mining producer of zinc, silver, gold, lead, and copper, located on private land in Owyhee County Idaho.

Thunder Mountain Gold Reports Significant Drill Intercepts in the Texas Zone at its High-Grade Polymetallic South Mountain Project Thunder Mountain Gold, Inc. reported on the latest analytical results from its Phase 2 underground diamond drilling program at the high-grade South Mountain Zinc-Silver-Gold-Copper Project (“South Mountain” or “South Mountain Project” or the “Property”) in southwestern Idaho, U.S.A. The Company`s 2020 drill results demonstrate that South Mountain’s Texas Zone contains both high-grade Copper-Silver and Zinc-Silver-Gold mineralization. The Company’s core drilling program intersected mineralization at depths beyond any historical drilling of the Texas Zone and the deposit remains open to depth. Further drilling results will be reported when received from the laboratories.
A total of 8,904 feet (2,714 meters) of underground core drilling was completed during Phase 2, with 30 holes in both the Texas and DMEA zones. During this drilling campaign, company site team widened and advanced the existing Sonneman level eastwards by 170 feet (52 meters) to establish a new drill station closer to the Texas Zone. With better access to drill the Texas Zone, a total of 24 holes were completed to test this zone of mineralization. Geological logging of the core supported by sampling results indicate that two styles of high-grade mineralization have developed in this area and are now identified as the Texas West and Texas East zones.
