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.

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 (Location): SECTION SUBDIVISIONS: THE CENTER OF THE S 1/2 OF 10

Comment (Development): RECENT URANIUM EXPLOR. INDICATES A FAIR U3O8 CONTENT (UP TO 0.15-0.20%), BUT IT OCCURRS IN COMPLEX STRUCTURE WITH F IONS WHICH MAKES IT ECONOMICALLY MARGINAL FOR EXTRACTION

Comment (Deposit): THE OVAL PIPE IS 6 FT LONG BY 4 FT MAX WIDTH AT SURFACE, AND 4 FT LONG BY 2 FT WIDE AT A DEPTH OF 22 FT BELOW THE SURFACE. ORE IS SOFT & FRIABLE & RANGES FROM DARK PURPLE-WHITE

Comment (Workings): WORKINGS CONSIST OF SEVERAL TRENCHES, PITS & 2 SMALL SHAFTS ON ORE PIPES, & A 64 FT. INCLINE

Comment (Geology): BEDS STRIKE N6W-N29E & DIP 25-42 DEG. NW.

Comment (Commodity): CHIEF IMPURITIES ARE MONTMORILLONITE, CREAM COLORED DOLOMITE & QUARTZ
