The South Mountain Mine is a polymetallic development project containing high-grade zinc, silver, gold,
and copper, and is located on private land approximately 70 miles southwest of Boise, Idaho. The
Project is on private land, permitting has been, and should remain straightforward. The Project was
intermittently mined from the late from 1940s to the late 1960s, by Anaconda Copper, with over 4,000

MSHA compliant. Thunder Mountain Gold Inc. purchased and advanced the project from 2007 through

processing at the Project has mostly come from high-grade Carbonate Replacement Deposits (CRD)
and skarn zones that remain open at depth and along strike. According to historical smelter records,
approximately 53,642 tons of mineralized material have been mined and direct shipped to the smelter,
with average grades;
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
