The Cobb Creek Prospect is a gold and silver mine located in Elko county, Nevada.
About the MRDS Data:
All mine locations were obtained from the USGS Mineral Resources Data System. The locations and other information in this database have not been verified for accuracy. It should be assumed that all mines are on private property.
Mine Info
Satelite View
MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Comments
Comment (Economic Factors): In their 1988 Annual Report, PanOrvana Resources reported a geologic resource for the deposit of 3.2 million short tons of material grading 0.045 opt gold (2900 kilotonnes of ore containing about 5 tonnes of gold). The McCall zone within this property has an estimated resource of over 173,000 ounces of gold.
Comment (Identification): This record replaces MRDS record No. MP90052 which is an incomplete entry for the same deposit.
Comment (Commodity): Ore Materials: gold
Comment (Deposit): The deposit consists of disseminated and stockwork gold-silver mineralization in argillized, potassium metasomatized, weakly silicified greenstone of the Valmy Formation.
Comment (Location): The prospect is located about 8 miles north of Maggie Summit
Comment (Workings): The prospect has been developed by drill roads and prospect pits
Comment (Development): The first reported prospecting was done by Pemberton Explorationsin 1983, who drilled at least six holes to test several gold-arsenic soil geochemical anomalies found on the property the prospect was explored and drilled by several companies in the 1980s. In 2004, Staccato Gold Resources Ltd. acquired the Cobb Creek gold property in the Independence Mountains district on a 50/50 basis with Bell Coast Capital Corp. The Cobb Creek property, which now comprises an area of 1,500 acres, has seen exploration by BHP, Newmont, Geomaque, and Orvana since the discovery of the mineralized zone in 1983. The McCall zone within this property has an estimated resources of over 173,000 oz Au.
