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 (Workings): OLD WORKINGS INCLUDE 1800-FT TUNNEL DRIVEN GENERALLY EASTWARD WITH THREE RAISES AND DRIFT. NEW DEVELOPMENT IS 492-FT TUNNEL

Comment (Deposit): MINE DEVELOPED ON WHAT CAN BE TERMED FOREST KING FAULT, WESTERNMOST OF SEVERAL PRINCIPAL QUARTZ-PYRITE VEINS IN PLATORO FAULT ZONE. FAUL TRENDS GENERALLY N 25 TO 30 W, DOWNDROPPED TO SW. MINE DEVELOPED AT INTERSECTION OF FOREST KING FAULT WITH NORTH-SOUTH-TRENDING FAULT (PART OF RESURGENT RADIAL FAULT SYSTEM WITH RESPECT TO CALDERA RIM) AND WITH N 75 TO 85 E-TRENDING EMMA CROSS-FAULT THAT EXTENDS NE THROUGH MAMMOTH-REVENUE PORTAL AND THAT IS PART OF RESURGENT FAULT SYSTEM OF CORNWALL BLLOCK.

Comment (Location): CLAIMS LIE ON NW SIDE OF FOREST KING MTN ABOVE AND PARTLY BELOW PLATORO RESERVOIR. ELEV AND LAT-LONG GIVEN ARE FOR TUNNEL PORTAL IN SE SE NE SEC. 21 (SECTIONS PROJECTED INTO UNSURVEYED AREA). ; INFO FROM LAND.ST :1975

Comment (Commodity): ORE MINERALS LISTED ABOVE ARE REPORTED FROM MAMMOTH-REVENUE MINE, AND ALTHOUGH NOT ALL SPECIFICALLY NOTED AT OTHER MINES IN DISTRICT, THEY ARE GENERALLY APPLICABLE TO THEM (BIRD, 1973). ARSENOPYRITE REPORTED BY PATTON (1917) CITED FOR ENTIRE DISTRICT. PETZITE (TELLURIDE) REPORTED BY PATTON IN GILMORE AND PLATORO DISTRICTS WAS PROBABLY MISIDENTIFIED SULFIDE (BIRD, 1973). MINOR PRODUCTION OF CU AND PB UNCERTAIN DUE TO LACK OF OLDER PRODUCTION RECORDS.

Comment (Production): PARTIAL PRODUCTION RECORD. NO FIGURES AVAILABLE PRIOR TO 1940.
