The Red Ledge Mine Area is a mine located in Sierra county, California.
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.

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.
Red Ledge Mine Area MRDS details
Primary: Red Ledge Mine Area
Land ownership: National Forest
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 (Geology): GEOL.DESC: AREA UNDERLAIN BY PROMINENT MASS OF SERPENTINITE THAT IS INTRUSIVE INTO OLDER ROCKS OF CALAVERAS GROUP AND TAYLOR FORMATION. LOCALLY, ESPECIALLY NEAR RED LEDGE MINE, SERPENTINITE WAS ALTERED TO SILICA-CARBONATE ROCK, WHICH CONSISTS OF MARIPOSITE, ANKERITE, SECONDARY QUARTZ IN VEINLETS, AND MAGNETITE. THE MARIPOSITE IS NICKEL BEARING. LYING UPON SERPENTINITE AND SILICA-CARBONATE ROCK IS MANTLE OF DEEP, NICKEL-BEARING REDDISH-BROWN LATERITE AND SILICA BOXWORK, UP TO 50 FT. DEEP IN PLACES. RANGE AND AVERAGE DEPTH UNKNOWN.
Comment (Deposit): Discovery Year: GOLD RECOVERED FROM LODE AND PLACER DEPOSITS SINCE MIDDLE 1850'S. NICKELIFEROUS LATERITE IDENTIFIED, 1975
