THUNDER MOUNTAIN GOLD IDENTIFIES A LARGE GOLD ANOMOLY AT THEIR SOUTH MOUNTAIN PROJECT
Elko, Nevada, March 23, 2010: Thunder Mountain Gold, Inc. (OTCBB: THMG) (Company), is pleased to announce the results of their 2009 soil and rock sampling grid conducted by the Company on the Gold Breccia Zone at South Mountain. The anomaly covers an area approximately one mile long by one-half a mile wide and is located approximately one-half mile south of the historic polymetallic mine area. A total of 236 soil samples were collected along with approximately 200 rock chip samples.
The goal of the sampling program was to better define the extent and quality of gold mineralization in the intrusive hosted Gold Breccia Zone. Systematic mapping and sampling of breccia outcrops were completed along with preliminary geologic mapping. A total of 236 soil samples were taken on the grid points and targeted the C soil horizon (where present), sieved in the field to 80-mesh, then delivered by Company personnel to ALS Chemex Laboratory for analytical work.
The results were plotted and confirmed an extensive gold anomaly with over 75% of the samples containing detectable gold that ranged from trace to up to 701 ppb. Base metal and minor element plots supported the structural control of the gold anomaly, and are interpreted to be consistent with high level leakage from a potential porphyry base metal/gold system at depth. A number of the samples were anomalous in zinc, copper, molybdenum, silver, and indium. Plots of these elements mirrored the orientation of the gold anomaly. Of note was the anomalous indium, and further review of the assay data from the underground portion of the South Mountain Mine shows anomalous indium, a potentially valuable bi-product of any future mining operation.
The intrusive breccia exposed in the anomaly consists of fragments of altered multi-compositional intrusive rock and silicified fragments of schist and marble. Initial rock chip samples from the outcrop area ranged from 0.49 ppm to 1.70 ppm gold, and follow-up outcrop and float sampling in 2009 yielded gold values ranging from 0.047 ppm to 5.81 ppm.
G. Peter Parsley, Vice President of Thunder Mountain Gold, said of the new target area, ?The gold anomaly at South Mountain is significant, and conceptually proves that we are dealing with a porphyry-type system, and with a broad zone of potassic alteration.?
Jim Collord, President of Thunder Mountain Gold, added,?The work completed in the Gold Breccia Zone significantly enhances the target potential at South Mountain. With this work we have identified three positive targets: the first being the potential of a near-surface gold deposit, the second pointing to the continued down dip extension of the marble-hosted polymetallic ore shoots, and the third being a large base metal-gold system at depth. We look forward to testing all of these target concepts with our 2010 drilling program.?
