Stormy Day Mine

The Stormy Day Mine is a tungsten mine located in Pershing county, Nevada at an elevation of 5,440 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 (Commodity): LAMPING OF ORE SHOWED IT TO BE OF VERY GOOD GRADE. AVERAGED 0.66% WO3.

Comment (Location): ACCESSIBLE BY GOOD DIRT ROAD ACROSS PRIVATE LAND WHICH IS FENCED AND POSTED (1985). ; INFO FROM LAND.ST :(1972)

Comment (Workings): 2 CROSS CUTTING ADITS DRIVEN UNDER MINERALIZED OUTCROP, AND LESSER ADITS AND PITS ABOVE AND ALONG THE N-S STRUCTURES; DRIFTS, STOPES. 4 LEVELS OF WORKINGS

Comment (Development): FIRST DEVELOPED DURING WWII. PRODUCTION FROM 1941 TO 1957 BY SHRINKAGE STOPE METHODS FROM 300 FEET OF DRIFTS 105 AND 125 FEET BELOW THE SURFACE AND 390-FOOT DRIFTS FROM THE MAIN ADIT. IN 1985, THE MAIN ADIT HAD AN ORE-BIN AND STOCKPILES OF ORE NEAR THE ENTRANCE, WHICH WERE SAMPLED (2921). DEPOSIT WAS FIRST EXPLORED BY SMALL ADITS AND TEST PITS ALONG THE OUTCROP ZONE FOR ABOUT 3 MILES. A LEASE AND OPTION WAS OBTAINED BY STANLEY F. O'LEARY, WHO EXPLORED THE SOUTH PART OF THE DEPOSIT WITH GOVERNMENT ASSISTANCE UNDER THE DMEA PROGRAM, DURING 1953-1954. OTHER INDIVIDUALS AND MINING COMPANIES LEASED THE PROPERTY FOR SHORT PERIODS UNTIL 1957. DIAMOND DRILLING IN 1953 INDICATED THAT ORE EXTENDED AT LEAST 100 FT BELOW THE LOWEST ADIT LEVEL. INACTIVE IN 1985; MINED IS LOCKED UP AND APPEARS TO HAVE BEEN SO FOR A CONSIDERABLE PERIOD OF TIME.

Comment (Deposit): THIS RECORD HAS BEEN MERGED WITH M234143 AS WELL AS M060203, M030092 AND D001180 WHICH HAVE BEEN DELETED.

Comment (Deposit): TACTITE BODIES OCCUR ALONG THE CONTACT OF MARBLIZED LIMESTONE/DOLOMITE AND GRANITE. THREE ORE SHOOTS OCCUR ALONG STRIKE OF THE CONTACT; THE CENTRAL ORE SHOOT IS FULLY DEVELOPED WHILE THE OTHER 2 ARE ONLY PARTIALLY DEVELOPED.
