Thunder Mountain Gold, Inc. Thunder Mountain Gold recently commissioned Kleinfelder to produce an independent assessment and validation of geological and mineral data for the South Mountain Mine. Kleinfelder reviewed previous site work, physiography, history, geology, and historical development and production data. They also developed a panel model using existing historical records to estimate total remaining mineral resources. Based upon such data, Kleinfelder`s panel modeling estimated an indicated resource of 629,979 tons containing 12,197,500 equivalent silver ounces. This resource is consistent with resource calculations by South Mountain Mines, Inc. and W.A. Bowes Company/J.R.Bowes in 1985, of 469,890 tons containing approximately 12,948,460 silver equivalent ounces. A copy of the report can be downloaded on this website.

Thunder Mountain Gold geologists are currently preparing a core drilling program at South Mountain, along with a development program that will open the Sonneman level for further exploration and underground drilling to test the extent of the mineralization.

Thunder Mountain Gold has initiated a property acquisition program in Arizona through the Company’s subsidiary, Thunder Mountain Resources. The Company is targeting precious and base metal deposits through lease agreements and the claim staking of public lands. Thunder Mountain Resources is focusing on detachment style mineralization related to structure between Precambrian and younger Paleozoic and Tertiary rocks.

Thunder Mountain Gold, Inc. was formed in 1978 when the owners of the claims containing the Sunnyside Deposit obtained Montgomery Mines, Inc. and gave it new life as Thunder Mountain Gold, Inc. in order to persue production on the property.

See the District History for a more detailed history of the Thunder Mountain property.

The Thunder Mountain property was put into production in the mid-1980's by Couer d'Alene Mines under a net profits agreement. It produced 100,000 ounces of gold and 200,000 ounces of silver until the property was relinquished back to TMG and surface-reclaimed in the early 1990's.

Subsequently the property was leased to and explored by several other companies, including Kennecott and USMX/Dakota Mining. A joint venture between the Company and Dewey Mining unified the mining district during this period, and USMX/Dakota Mining expended approximately $4 million to explore the district and define a significant measured mineral resource on the Dewey property.
