Boise, Idaho, and Elko, Nevada, September 1, 2010: Thunder Mountain Gold, Inc. (OTCBB: THMG, TSX-V – Pending) (Company), a US-based exploration company focused on discovering and defining high grade, high quality precious and base metal resources, is pleased to announce the positive results of its road cut sampling program completed in July on the Intrusive Gold Breccia Zone at South Mountain. The Company completed approximately two miles of exploration road to access and drill the broad gold-bearing breccia defined by the soil sampling program completed last year by Company geologists. The results confirmed an extensive gold anomaly with all but two of the samples containing detectable gold.
A total of 115 road cut samples were collected along the new roads in 100-foot, 50-foot or 25-foot intervals, depending upon whether the road was in soils, colluvium or bedrock. Over 8,700 feet of roads were sampled as part of the program. The average value of all samples averaged 132 parts per billion (ppb), or 0.004 ounce per ton (opt). The 2,600 feet of road cuts within the main anomaly target areas averaged 497 ppb (0.015 opt). The values ranged up to 859 ppb, or 0.025 opt, over 25 feet or road cut. The road samples confirmed the geological structural control that has been outlined by geologic mapping along with rock chip and soil sampling programs.
Jim Collord, President of Thunder Mountain Gold, commented, “The preliminary sample results are outstanding and increase our confidence in the South Mountain gold target discovered by the Company. The sample geology and gold values exposed by the new roads show the target has the potential to be more extensive than we initially expected. We look forward to the start of our drilling program to test the vertical extent and grade of the large anomaly. The drilling is scheduled to start by mid-September.”
The goal of the sampling program was to better define the extent and quality of gold mineralization in the intrusive hosted intrusive gold-bearing breccia, an anomaly that covers an area approximately one mile long by nearly one-half a mile wide and is located approximately one-half mile south of the historic South Mountain polymetallic mine area. Systematic mapping and sampling of breccia outcrops were completed along with preliminary geologic mapping. The road cut samples were screened in the field to quarter-inch minus in areas of areas of poor outcrop with rock chips being collected in bedrock zones, then delivered by Company personnel for analytical work to ALS Chemex Laboratory in Elko, Nevada.
The intrusive breccia exposed in the road cut consists of fragments of altered multi-compositional intrusive rock and silicified fragments of schist and marble. Initial rock chip samples from 2009 exploration in the outcrop area ranged from 490 ppb to 1700 ppb gold, and follow-up outcrop and float sampling in 2009 yielded gold values ranging from 47 ppb to 5,810 ppb. The 2009 soil sampling program of 236 samples confirmed the extent of the anomaly with values ranging up to 700+ ppb. Approximately 75% of them contained anomalous gold values.
About Thunder Mountain Gold, Inc.:
Thunder Mountain Gold, founded in 1935, is an exploration company focused on discovering and defining high grade, high quality precious and base metal projects primarily in politically stable regions such as the Western United States. Thunder Mountain Gold performs its own natural resource exploration and generates value for shareholders by demonstrating the value of its properties through a comprehensive drilling program and then seeking strategic partners to move the properties into production. South Mountain, its flagship property located in Owyhee County Idaho — just north of the Nevada border, is 100% owned/controlled with 17 patented mining claims, along with private leases totaling over 1,200 acres. The Company’s other precious metals properties include Clover Mountain in Idaho, the Trout Creek and West Tonopah in Nevada, along with two properties in Arizona.
