The Bonanza King Mine is a gold mine located in Pershing county, Nevada at an elevation of 4,951 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.
Elevation: 4,951 Feet (1,509 Meters)

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.
Bonanza King Mine MRDS details
Primary: Bonanza King Mine
Secondary: Lady Mary
District: Spring Valley District
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.

Comment (Deposit): DISCOVERED IN 1868, UNDER THE NAME LADY MARY, THEN RELOCATED IN 1871 AS THE EAGLEMINE. THE MINE WAS ACTIVELY WORKED DURING THE PERIOD 1868-85, THEN INTERMITTENTLY UNTIL 1910. THE MINE IS DEVELOPED ON A STEEPLY DIPPING, NW-TRENDING QUARTZ-TOURMALINE VEIN IN AN ALTERED DIABASE DIKE IN ROCHESTER RHYOLITE. THE VEIN WAS MINED BY DRIFTING EASTWARD FROM A SHAFT AT WEST END OF THE MINE STOPED TO THE SURFACE ALONG A LENGTH OF ABOUT 200 TO 250 FEET. ; INFO.SRC : 1 PUB LIT; 2 UNPUB REPT
Comment (Deposit): THE STEEPLY-DIPPING, NW-TRENDING QUARTZ-TOURMOLINE VEIN IS 2 1/2 TO 5 FT WIDE TERMINATING ON THE WEST END IN DIABASE DIKE AND ON THE EAST END AT A NORTHEAST TRENDING FAULT. TOURMALINE REPLACED QUARTZ AFTER SULFIDE MINERALIZATION. VISIBLE GOLD WAS OBSERVED AS FLAKES IN LIMONITE (FROM PYRITE), IN TETRAHEDRITE, AND RARELY IN GALENA. ORE DEPOSIT IS GENETICALLY RELATED TO THE GRANODIORITE STOCK EXPOSED IN SPRING VALLEY AND THE DIABASE DIKE THAT INTRUDES THE RHYOLITE MAY BE AN OFF SHOOT FROM THIS BODY.; MODEL NAME COULD ALSO BE: POLYMETALLIC VEINS.
Comment (Location): PREVIOUS QUAD DESIGNATION = UNIONVILLE (1954) 1:625000
Comment (Production): TOTAL PRODUCTION UNKNOWN, ESTIMATED OVER $50,000
Comment (Workings): THE VEIN WAS MINED BY DRIFTING EASTWARD FROM A SHAFT AT THE WEST END OF THE MINE STOPED TO THE SURFACE ALONG A LENGTH OF ABOUT 200 TO 250 FT.
Comment (Geology): VEIN IS 2 1/2 TO 5 FEET TERMINATING ON THE WEST END IN DIABASED DIKE AND ON EAST END AT A NORTHWEST TRENDING FAULT. TOURMALINE REPLACED QUARTZ AFTER SULFIDE MINERALIZATION. VISIBLE GOLD WAS OBSERVED AS FLAKES IN LIMONITE (FROM PYRITE), IN TETRAHEDRITE, AND RARELY IN GALENA. ORE DEPOSIT IS GENETICALLY RELATED TO THE GRANODIORITE STOCK EXPOSED IN SPRING VALLEY AND THE DIABASE DIKE THAT INTRUDES THE RHYOLITE MAY BE AN OFF SHOOT FROM THIS BODY.
Comment (Development): FIRST EXPLORED UNDER THE NAME LADY MARY, THEN RELOCATED IN 1871 AS THE EAGLEMINE. IT WAS ACTIVELY WORKED DURING 1868-85, THEN, INTERMITTENTLY UNTIL 1910.
