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.

Comment (Deposit): Discovery Year: 1870'S

Comment (Location): 3/4 MILE N OF CASTLE DOME MINE ; INFO FROM LAND.ST :(1979)

Comment (Production): PRODUCTION INCLUDED UNDER OLD DOMINION PRIOR TO 1931 IN ABGMT-USBM DATA 14,300 TONS REPORTED IN 1906 TO 1908. ORE GRADES 1906-1936 WERE 5.2 PERCENT CU, 0.06 OUNCES/TON AU 3.4 OUNCES/TON AG. AFTER 1936, GRADES FELL ABRUPTLY

Comment (Development): NOW INCLUDED IN CASTLE DOME PROPERTY. OPERATED BY OLD DOMINIOM CO UNTIL 1929, BOUGHT OUT BY MIAMI COPPER CO IN 1931, LATER BOUGHT BY CITIES SERVICE CO.

Comment (Deposit): MAIN VEIN HAS CURVED COURSE, NE TREND AT E END, NW TREND AT W END BELOW ABOUT 100 FT. VEIN PASSES INTO MINERALIZED POPRHYRY.

Comment (Workings): IN 1903, FIVE TUNNEL LEVELS, THREE WITH CROSS CUTS AND DRIFTS, AND SOME SMALLER SHAFTS. MAIN TUNNEL N TRENDING FOR 215 FT BEFORE MAIN WORKINGS ARE ENCOUNTERED

Comment (Geology): HYPOGENE MINERALIZATION SAME AS THAT OF THE CASTLE DOME MINE, 1/2 MILES, AND MINERALIZATION PERIOD IS ALSO THE SAME.
