Thunder Mountain Gold Identitifies New and Significant Gold Anomaly at Their South Mountain Project

Thunder Mountain Gold, Inc. announced that it has identified anomalous gold mineralization in previously unexplored, multi-lithic intrusive breccia at the Company’s 100% owned and controlled South Mountain property in Owyhee County, Idaho. The newly identified gold targets significantly raise the potential for discovery of gold resources on the 868 acres of private land that make up the Company’s South Mountain property.

Anomalous gold mineralization was discovered through rock chip sampling and a soil orientation survey on private land leased by the Company. All 20 rock chip samples obtained from outcrop and float in the mineralized area were anomalous with gold values ranging from 0.047 ppm to 5.81 ppm. In a 24-sample, 100-foot spaced soil orientation survey in one area resulted in 23 of the samples being anomalous with gold values ranging up to 0.31 ppm. All assays were completed by ALS Chemex in Elko, Nevada.

The gold mineralization occurs in a multi-lithic intrusive breccia that covers an area of at least 60 acres and is oriented parallel to copper, zinc, silver, gold, and lead mineralization at the main South Mountain located one-half mile to the north. The breccia has sub-angular fragments of sulfidized and potassically altered quartz monzonite and silicified fragments of metasediments.

Thunder Mountain Gold is systematically mapping and sampling the multi-lithic intrusive breccia areas at South Mountain to define the surface extent of the anomalous gold mineralization. The South Mountain property is a precious metals project, with base metal mineralization at the core. Work completed by the Company during 2008 demonstrated that there is a potential for deeper base metal-gold mineralization associated and a larger gold system surrounding the historic mine. An extensive sample soil geochemical survey over the target area is planned to be completed by fall of 2009.

Jim Collord, President of Thunder Mountain, said of the new gold anomaly at South Mountain, “We are very excited about the favorable analytical results and the unique geology in this newly-recognized and extensive area. This changes the dynamics of South Mountain because it enhances our geologic model and demonstrates the potential for a much larger precious metal deposit associated with the mineralizing event.”
