The Copperhead Mine is a gold, silver, and copper mine located in Saguache county, Colorado at an elevation of 8,599 feet.
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.

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.

Analytical Data
Analytical Data: Sampling by Ellis and others (1983) produced grades up to 0.58 oz/ton gold, 2.8 oz/ton silver, and 2% copper from iron- and copper-stained gneissic fault gouge, silicified fault breccia, and quartz veins.
Materials
Ore: Chalcopyrite
Ore: Galena
Ore: Pyrite
Gangue: Quartz
Gangue: Epidote
Gangue: Specularite
Comments
Comment (Geology): Mineralization is characterized by intense silica replacement of breccia matrix along a low-angle fault (Benson, 1997). The low-angle fault is similar to that at the large, modern san Luis Mine further south.
Comment (Location): Near Spring Creek at the western base of the Sangre de Cristo Mountains, about 10 miles north-northwest of the town of Crestone. This is the main mine of the Blake district.
Comment (Production): See entry on Blake district for production info.
Comment (Reserve-Resource): Sampling by Ellis and others (1983) produced grades up to 0.58 oz/ton gold, 2.8 oz/ton silver, and 2% copper from iron- and copper-stained gneissic fault gouge, silicified fault breccia, and quartz veins.
Comment (Workings): 25-FT-HIGH HILLSIDE CUT
Comment (Development): EPLORATION AND OPEN CUT DEVELOPMENT IN 1958 TO MINE COPPER ORE AN D SMELT IT AT SMELTER UNDER CONSTRUCTION BELOW MINE.
