Granite Mountain Cu-Mo Property

The Granite Mountain Cu-Mo Property is a copper and molybdenum mine located in Pershing county, Nevada at an elevation of 6,841 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.

Comments

Comment (Deposit): Discovery Year: MID 1970'S

Comment (Location): ON TOP OF RIDGE AT HEADS OF WATER CANYON AND KENNEDY CANYON . INFO FROM LAND.ST :(1972)

Comment (Development): DISCOVERED EARLY 1980 BY GEOCHEMISTRY; NO ACTIVITY IN 1984. IN THE MID-1970'S, W.A. BOWES INC. FOUND ANOMALOUS COPPER VALUES IN SOILS OVER A BROAD AREA OF GRANODIORITIC ROCKS ON NORTH FLANK OF GRANITE MOUNTAIN. DIAMOND DRILLING OUTLINED OVERLAPPING ZONES OF MO AND CU IN THE SUBSURFACE (FIRST AT 100 FT BELOW SURFACE). THE ZONES RICH IN MOLYBDENITE AND CHALCOPYRITE ARE ABOUT 460 M WIDE, BUT OCCURRENCES OF MOLYBDENITE AND CHALCOPYRITE IN DRILL CORE EXTEND OVER A MUCH LARGER AREA.

Comment (Deposit): CU-MO MINERALIZATION IS REPORTED FROM THE GRANODIORITE ROCKS OF GRANITE MOUNTAIN. WIDESPREAD K-METASOMATISM IS REPORTED.

Comment (Workings): OVER 10 KM OF DRILL AND ACCESS ROADS; PROBABLY OVER 1 DOZEN ROTARYDRILL HOLES

Nevada Gold

Nevada has a total of 368 distinct gold districts. Of the of those, just 36 are major producers with production and/or reserves of over 1,000,000 ounces, 49 have production and/or reserves of over 100,000 ounces, with the rest having less than 100,000 ounces. Read more: Gold Districts of Nevada.
