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.

Comments

Comment (Deposit): ORE IS IN OVERLAPPING QUARTZ LENSES. HANGING WALL PORTION OF LENSES IS GENERALLY BETTER-GRADE ORE THAN IS THE FOOTWALL PORTION

Comment (Deposit): MINE WAS SOLD TO CORD INTERESTS BY BLACK MAMMOTH. CORD GROSSED OVER $2 MILLION FROM 289,857 TONS, BUT OPERATIONS WERE NOT PROFITABLE AND THE MINE CLOSED DOWN SHORTLY AFTER PEARL HARBOUR ATTACK. SOME ; INFO.SRC : 1 PUB LIT; 5 PERS COMM

Comment (Workings): 2 TUNNELS RUNNING SW; THE LONGER ONE 1100 FT. LONG IN 1906; WINZES, INCLINES; GLORY HOLE; 28,317 FT. OF WORKINGS WERE DEVELOPED FROM 1936 TO 1941 UNDER CORD INTERESTS (THIS INCLUDED ALL THE MARY MINE WORKINGS ON MANY CLAIMS.) IN 1981, IT WAS ESTIMATED THAT THERE WERE ABOUT 60 MILES OF UNDERGROUND WORKINGS IN THE MARY MINE.

Comment (Geology): FREE GOLD ORE IN UPPER WORKINGS; MORE SULPHIDES CARRYING GOLD IN LOWER WORKINGS. SULPHIDES ARE IN CRACKS IN THE QUARTZ, AND COAT CREVICES IN SILICEOUS LIMESTONE PARTINGS IN QUARTZ.

Comment (Development): MARY CLAIM WAS PATENTED TO JOHN CHIATOVICH IN 1891, AND CAME INTO POSSESSION OF THE MOHAWK-ALPINE MINING CO. IN 1904, AFTER WHICH IT AND MANY OTHER CLAIMS WERE CONSOLIDATED UNDER THE PITTSBURG-SILVER PEAK GOLD MINING CO. IN 1906. PITTSBURG BEGAN LARGE-SCALE OPERATIONS IN 1906, HAVING ACQUIRED ALL MAJOR CLAIMS IN DISTRICT

Comment (Deposit): MOST OF PITTSBURG'S OPERATIONS WERE CARRIED ON THROUGH THE OLD MARY TUNNEL, WHICH WAS EXTENDED AND EQUIPPED WITH ELECTRIC RAILWAY AND LIGHTS. THEY CALLED THEIR OPERATIONS "THE MARY MINE" ALTHOUGH IT ACTUALLY ENCOMPASSED MANY CONTIGUOUS MINING CLAIMS BESIDES THE MARY CLAIM. IN 1908 PITTSBURG COMPLETED A 100-STAMP MILL TO WHICH 20 MORE STAMPS WERE ADDED IN 1909, MAKING IT THE LARGEST MILL IN NEVADA, TREATING 540 TPD. IN 1915, PITTSBURG WAS NO LONGER ABLE TO MAKE A PROFIT AND THEY CLOSED DOWN. IT REMAINED IN ACTIVE UNTIL ABOUT 1928. IN 1928-1929, BLACK MAMMOTH CONSOLIDATED MINING CO. BEGAN OPERATIONS AT THE OLD MARY MINE, BY PURCHASING THE SUBLEASE FROM ALBERTOLI. THE PROPERTY WAS AT THAT TIME OWNED STILL BY PITTSBURG SILVER PEAK GOLD MINING CO., AND LEASED BY LUCKY BOY DIVIDE MINING CO. IN 1936, BASIL PRESCOTT SUBLEASED SOME OF THE MARY MINE PROPERTIES, INCLUDING THE MARY CLAIM. IN 1935, BLACK MAMMOTH BUILT A NEW 100 TPD BALL MILL TO COMPLY WITH LEASE PROVISIONS. ALSO IN 1936, THE MARY
