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.
