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 (Deposit): IN MINOR SHEAR ZONES IN THE DOLOMITE AND CONGLOMERATE, AND AS SMALL REPLACEMENT LENSES IN DOLOMITE. SEVERAL MINERALIZED AREAS OCCUR IN AN E-TRENDING BELT; THE LARGEST AREA 300 FT X 135 FT, LENSES OF NEARLY PURE HEMATITE AND PARTLY REPLACED DOLOMITE AND CONGLOMERATE ARE INTERMIXED WITH SMALL MASSES OF UNREPLACED COUNTRY ROCK.

Comment (Development): A FEW TONS OF IRON ORE WERE PRODUCED IN 1952 BUT THE OPERATION WAS SHUT DOWN DUE TO DIFFICULTY OF MAINTAINING A 57% FE MINIMUM GRADE

Comment (Workings): 2 PITS SHOWN ON TOPO SHEET, SHAFT, 40' ADIT, "CUTS" REPORTED (1958)

Comment (Location): A FEW MILES SW OF THE MAIN ROCK HILL DISTRICT . TO SHAFTS IN MINE AREA. UTM IS TO ONE OF SEVERAL WORKINGS. ; INFO FROM LAND.ST :(1972)

Comment (Production): DIFFICULTY IN MAINTAINING MINIMUM GRADE OF 57% FE HALTED MINING

Comment (Geology): CONGOLMERATE=CANDELARIA FM SLATE, QUARTZITE=PALMETTO FM. DOLOMITE=DIABLO FM.
