South Mountain Field Work For Exploration Season Has Commenced

BOISE, ID – Thunder Mountain Gold, Inc. reported that field work for the 2025 Exploration season has begun at its flagship 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.

“The 2025 exploration program at South Mountain highlights our clear focus on moving the project toward drilling and resource expansion,” commented Eric T. Jones, President & CEO. “With the upgraded technical database — including targeted geophysical and geochemical data — we are confident this will guide a highly-productive drill campaign. Field work now sets the stage for what we believe could be a pivotal phase in South Mountain’s development.”
