Granite Creek Mine

The Granite Creek Mine is a tungsten mine located in Humboldt county, Nevada at an elevation of 5,499 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: Private
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 (Geology): MAIN TACTITE BODY LAY IN KEEL & LOWER PART OF TROUGH-LIKE STRUCTURE, VERY VARIABLE IN SIZE AND SHAPE THE CONTACT IS GENERALLY EAST-WEST WITH NUMEROUS IRREGULARITIES. IRREGULAR AND DISCONTINUOUS TACTITE BODIES OCCUR ALONG THE CONTACT FOR OVER 2200 FT.

Comment (Location): ON GRANITE CREEK; SW 1/4 SEC. 29

Comment (Deposit): OCCURRENCE OF SCHEELITE WAS KNOWN FOR SOME TIME BEFORE ORE WAS MINED IN 1942. MAINLY UNDERGROUND WORKINGS, FROM 1942 TO 1944 AND FROM 1950 TO 1955. THE PROPERTY IS ESTIMATED TO HAVE ABOUT 42,200 TONS ORE AT 0.45% WO3 RESERVES. MAIN PRODUCTION WAS FROM THE MAIN TACTITE BODY AT THE EAST END OF THE OREBODY. WORKINGS CONSIST OF 2 ADITS CONNECTED TO 2 GLORY HOLES; PITS AND TRENCHES. ; INFO.SRC : 1 PUB LIT; 2 UNPUB REPT

Comment (Deposit): SCHEELITE IS IRREGULARLY DISTRIBUTED AND IS ENTIRELY ABSENT FROM MUCH OF THE TACTITE. WHERE THE CONTACT IS ABOUT P-ARALLEL TO THE STRIKE OF THE LIMESTONE, THE TUNGSTEN MINERALIZ-ATION IS MORE NEARLY UNIFORM THROUGHOUT THE WHOLE MASS OF TACT-ITE. WHERE THE CONTACT IS AT AN ANGLE TO THE STRIKE OF SEDIMEN-TARY BEDS, THE TACTITE BODIES AND THE ORE ZONES WITHIN THEM AR-E MORE IRREGULAR AND MAY PITCH IN THE DIRECTION OF THE DIP OF -THE BEDS. THE LARGEST AND MOST CONTINUOUS TACTITE OREBODY IS A-T THE EASTERN END OF THE PROPERTY. THE MAIN LAYER HAS BEEN TRA-CED FOR 230 FT ON THE SURFACE WHERE ITS WIDTH RANGES FROM 5 TO- 25 FT. ON THE LOWER ADIT LEVEL IT IS 200 FT LONG. THE AVERAGE- WIDTH IS BETWEEN 15 AND 20 FT AND THE TUNGSTEN CONTENT IS R- ATHER UNIFORMLY ABOUT 0.6 % WO3, WHICH WAS DILUTED SOMEWHAT - IN MINING.

Comment (Workings): 2 ADITS, 2 GLORY HOLES, PITS, TRENCHES

Comment (Production): MINE YIELDED 88000 TONS ORE AVERAGING 0.5 % WO3 IN 1942-1944 AND AN ADDITIONAL 18629 TONS IN 1946.ALL OF THIS ORE -WAS MINED FROM THE EASTERN PART OF THE MINE BY UNDERGROUND WOR-KINGS AND 2 GLORY HOLES. IN 1951, OPEN PIT MINING OF THE TIP-T-OP DEPOSIT AT THE WEST END OF THE PROPERTY BEGAN AND CONTINUED- THROUGH 1956, YIELDING ABOUT 37200 TONS ORE. AN ADDITIONAL 18-8000.TONS WERE ALSO MINED FROM THE UNDERGROUND WORKINGS DURING- THE PERIOD FROM 1955, BY THE GETCHELL MINING CO.
