Granite Mountain Drill Site 101

The Granite Mountain Drill Site 101 is a copper and molybdenum mine located in Pershing county, Nevada at an elevation of 6,660 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.

Analytical Data

Analytical Data: SAMPLE 2332 CONSISTS OF CORE CHIPS AND FINELY GROUND ROCK FROM A DIAMOND DRILL HOLE, PROBABLY HOLE 101 OF BOWES (1982). THE SAMPLE MAY BE CONTAMINATED BY DRILLING FLUID, SURFACE ROCK MATTER, ETC., AS IT WAS COLLECTED FROM AROUND THE DRILL PAD. IT CONTAINS 10% FE, 3% MG, 7% CA, 1% TI, 3000 PPM MN, 2 PPM AG, 70 PPM B, 5000 PPM BA, 2 PPM BE, 20 PPM CO, 150 PPM CR, 1500 PPM CU, 200 PPM LA, 700 PPM MO, 70 PPM NI, 150 PPM PB, 20 PPM SC, 20 PPM SN, 2000 PPM SR, 200 PPM V, 50 PPM Y, 200 PPM ZR.

Comments

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

Comment (Development): NO ACTIVITY IN 1984

Comment (Location): ON SLOPE OF RIDGE EAST OF EASTERNMOST FORK OF SAY CANYON . INFO FROM LAND.ST :(1972)

Comment (Deposit): MOLYBDENITE, PYRITE AND CHALCO PYRITE WERE NOTED IN DRILL CORE CHIPS FROM THIS DRILL HOLE. PROPERTY IS REPORTED TO CONTAIN CU. MO MINERALIZATION IN GRANODIORITE, CORE CHIPS APPEAR TO BE MORE SILICIC THAN GRANODIORITE.

Comment (Workings): NUMEROUS DRILL ROADS AND DRILL HOLES
