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): ORE LOCALIZED IN QUARTZ-PYRITE AND QUARTZ-CARBONATE-PYRITE VEINS DEPOSITED IN FAULTS AND FRACTURES RELATED TO EMPLACEMENT OF WHITE ROCK PLUTON. COUNTRY ROCK IS MAROON FM CLASTICS LOCALLY METAMORPHOSED TO HORNFELS BY GRANODIORITE STOCK AND NUMEROUS DIKES AND SILLS. WESTON'S (1910) DESCRIPTION ALSO INDICATES DISSEMINATED ORE IN MATRIX REQUIRING BENEFICIATION. THICKNESS OF SMELTER ORE IS 3 FT ON TAM O'SHANTER VEIN AND 2.5 FT ON MONTEZUMA VEIN. CONCENTRATING ORE IS 4 TO 6 FT ON TAM O'SHANTER VEIN AND 5 TO 8 FT ON MONTEZUMA VEIN.
Comment (Production): PARTIAL PRODUCTION RECORD. MINE INACTIVE 1916-1959 AND AFTER 1960
Comment (Workings): AS OF 1907, ABOUT 5500 FT OF CROSSCUTS, DRIFTS, WINZES, RAISES, AND SHAFTS, PLUS SURFACE WORKINGS
Comment (Development): DISCOVERED BY PROSPECTORS ON 9/23/81, PROMINENT VEIN OF SOLID ORE STOOD ABOVE GROUND SURFACE DUE TO EROSION RESISTANCE, FIRST WORKED BY SURFACE OPERATION, BUT HIGHER ZN CONTENT AT DEPTH AND LACK OF ADEQUATE ROADS FORCED CLOSURE. AFTER NEW ROADS AND RR. TO A SPEN BUILT AND NEW ZN-SEPARATION METALLURGY DEVELOPED, MINE REOPENED BY TUNNEL AND EXTENSIVE UNDERGROUND WORKINGS.
