Thunder Mountain Kicks Off 2025 Exploration
at South Mountain
Field work underway as preparation begins for the upcoming
drilling campaign
Boise, Idaho--(Newsfile Corp. - July 7, 2025) - Thunder Mountain Gold, Inc. (OTCQB: THMG) (TSXV:
THM) (the "Company") is excited to announce 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.
This phase of fieldwork includes:
Comprehensive surface mapping and chip-channel sampling across key carbonate replacement
deposits (CRD)_/skarn and porphyry-hosted zones.
Draped 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.
"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."
Next steps:
Following the completion of this phase of field program, Thunder Mountain plans to interpret the data and
generate drill targets for Q4 drilling. Permitting for drilling is in progress, leveraging existing approvals for
underground and surface exploration.

The South Mountain Project
The South Mountain Mine is a polymetallic development project containing high-grade zinc, silver, gold,
and copper, and is located approximately 70 miles southwest of Boise, Idaho. The Project is on private
land, permitting has been, and should continue to be a clear-cut process. The Project was intermittently
mined from the late from 1940s to the late 1960s, most notably by Anaconda Mining.
Over 4,000 feet of
underground workings have been MSHA compliantly rehabilitated, re-engineered, and maintained in
preparation for mining. Thunder Mountain Gold Inc. purchased and advanced the project from 2007
through Present, with expenditures into the project of approximately US$25 million. Historic test mining
and processing at the Project has mostly come from high-grade CRD and skarn zones that remain open
at depth and along strike. According to historical smelter records, approximately 53,642 tons of
mineralized material were mined and direct shipped to the historic Toole Utah smelter, with average
grades of;
14.5% Zn, 10.6 o.p.t. Ag (363.42 g/t Ag), 0.058 o.p.t. Au
(
1.98 g/t Au), 1.4% Cu, and
2.4% Pb
were realized (See SK-1300 Technical Resource Statement, and NI 43-101 Technical Report:
Updated Mineral Resource Estimate for the South Mountain Project, dated December 31, 2023, and
December 15, 2023, respectively. More details are available at
