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 (Deposit): PRINCIPAL LODE IS AMETHYST FAULT (ATTITUDE ABOVE). MINE ALSO DEVELOPS ANCESTRAL AMETHYST FAULT (DEAN FAULT) WHICH LIES IN AMETHYST HANGING WALL BUT STRIKES MORE NORTHERLY (N 5 TO 10 W) AND DIPS MORE STEEPLY (70 TO 80 SW). LATER MINERALIZED FRACTURES OCCUPY HORSE BETWEEN THE TWO FAULTS. ANOTHER MAJOR FRACTURE SUBPARALLELS AND LIES JUST WEST OF DEAN FAULT BUT DIPS STEEPLY NE. SOUTHERN AMETHYST FAULT MINERALIZATION IS VEIN-TYPE AND DISSEMINATED, BOTH CONFINED TO DENSELY FRACTURED AND BRECCIATED CAMPBELL MTN. RHYOLITE IN HANGING WALL BUT IN SOME PLACES ALSO IN FOOTWALL. TWO-STAGE PARAGENESIS INCLUDES 1) STAGE 1, QUARTZ, BARITE, RHODOCHROSITE, NO AG; 2) STAGE 2, SUBSTAGE A, QUARTZ, AMETHYST, BASE-METAL SULFIDES, NO AG; SUBSTAGE B, AMETHYST, BARITE, BASE-METAL SULFIDES, AG-BEARING CU SULFIDES (ECONOMIC); SUBSTAGE C, QUARTZ, AMETHYST, CU AND BASE-METALS SULFIDES, FE-MN OXIDES, TETRAHEDRITE, ACANTHITE AND NATIVE AG ECONOMIC, ALSO PROBABLE DISSEMINATED MINERALIZATION IN CLOSELY
Comment (Deposit): SPACED MICROVEINLETS AND INTERGRANULAR PORE FILLING.
Comment (Workings): MINE DEVELOPED BY 4 TUNNELS AND NELSON-WOOSTER-HUMPHREYS TUNNEL (LOWEST) OVER 1175-FT VERTICAL INTERVAL. TUNNEL 4 IS 445 FT ABOVE NELSON TUNNEL; TUNNEL 3 IS 401 FT ABOVE TUNNEL 4; TUNNEL 1 IS 330 FT ABOVE TUNNEL 3. TUNNEL 2 (INACCESSIBLE) POSITION UNKNOWN. BACHELOR SHAFT (WITH SEVERAL HUNDRED FEET OF DRIFTS) SUNK TO 125 FT BELOW NELSON TUNNEL. TOTAL EXTENT OF WORKINGS UNKNOWN BUT EXCEEDS 10,000 FT ON 4 MAIN LEVELS.
Comment (Production): AMTS. OF METALS CALCULATED FROM REPORTED ORE GRADES
Comment (Location): S-T-R, LAT-LONG, AND ELEV DETERMINED FROM EMMONS AND LARSEN'S (1923) TOPO MAP (1:24,000). MINE OR CLAIM LIES ON SE SIDE OF BACHELOR MTN. ; INFO FROM LAND.ST :(1976)
Comment (Development): LOW-GRADE ORE MINED SOON AFTER DISCOVERY, TREATED WITHOUT SUCCESS AT SUNNYSIDE. WORK RENEWED WITH DEVELOPMENT OF OTHER LARGE LODE DISCOVERIES IN 1891.
