The Unnamed Copper Mine is a copper mine located in Humboldt county, Nevada at an elevation of 5,259 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.

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.

Land Status

Land ownership: BLM Administrative Area
Note: the land ownership field only identifies whether the area the mine is in is generally on public lands like Forest Service or BLM land, or if it is in an area that is generally private property. It does not definitively identify property status, nor does it indicate claim status or whether an area is open to prospecting. Always respect private property.

Materials

Ore: Malachite

Comments

Comment (Development): WORKED IN EARLY 1900'S, WITH OLD TAILINGS FROM THIS ERA IN A SMALL WASH EAST OF THE SHAFT. NO ACTIVITY IN 1984.

Comment (Workings): SEVERAL PITS AND SHALLOW SHAFTS, ONE OF WHICH IS SHOWN ON THE TOPO MAP. BULLDOZING IN THE LAST FEW YEARS AND A VER-Y SMALL-SCALE ATTEMPT TO BATCH LEACH SOME ORE, PROBABLY FOR PR-ECIOUS METALS.

Comment (Deposit): OXIDE COPPER MINERALS AND IRON AND MN OXIDES OCCUR ALONG A PROBABLE SHEAR ZONE IN GREENSTONE AND CHERT OF THE PUMP-ERNICKEL OR HAVALLAH FMS. SIMILAR MINERALIZATION IS PRESENT IN- A POSSIBLE LOW-ANGLE NORTH-TRENDING FAULT ZONE IN A SMALL PIT- SW OF THE MAIN SHAFT. LITTLE OBVIOUS HYDROTHERMAL ALTERATION;- THE GREENSTONE MAY BE LOCALLY ARGILLIZED.
