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 (Location): INFO FROM LAND.ST :(1978); LATITUDE-LONGITUDE VALUES CALCULATED FROM TOWNSHIP, RANGE, SECTION.
Comment (Deposit): THE HOST ROCK ON THE LETA LYNN PROSPECT IS ARGILLIZED PURPLE ANDESITE PORPHYRY. A MINERALIZED FAULT ZONE ABOUT 16 FT WIDE, STRIKING N 20 W AND DIPPING 80 SW, CUTS ACROSS THE PROSPECT. ROCK AND VEIN MATERIAL IN THE FAULT ZONE ARE STRONGLY SILICIFIED. FLUORSPAR OCCURS IN IRREGULAR VEINS (8 TO 10 IN WIDE) AND PODS ALONG THE NW TRENDING FAULT. THE PODS AND VEINS CONTAIN COARSELY CRYSTALLINE FLUORITE, WITH MILKY QUARTZ, AND MINOR AMOUNTS OF PYRITE AND MN-OXIDES. ANDESITE BRECCIA IN THE FAULT ZONE IS PARTIALLY REPLACED BY FINELY CRYSTALLINE FLUORITE. THE FLUORITE IS PREDOMINANTLY WHITE AND GREEN WITH A SMALL AMOUNT OF BLUE.
Comment (Development): ABOUT 3 TONS OF FLUORITE ORE WERE SOLD TO BISHOP BAILEY IN DEMING IN 1972. A FEW PERCUSSION HOLES WERE DRILLED ON THE PROPERTY IN THE EARLY 1970'S.
Comment (Workings): WORKINGS CONSIST OF SEVERAL TRENCHES, THE LARGEST OF WHICH IS 3 TO 8 FT DEEP, ABOUT 10 FT WIDE, AND 35 FT LONG.
