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): LOCAL SMALL PODS OF SULFIDES WITHIN 200 FEET OF THE GROUND SURFACE, ALTHOUGH THE MAJOR PART OF THE ORE IS THOROUGHLY OXIDIZED TO A GREATER DEPTH. GOLD WAS AN IMPORTANT CONSTITUENT IN THE EARLY PRODUCTION OF THIS MINE
Comment (Commodity): ORES MORE QUARTZOSE THAN THE MINES NEAR PICKHANDLE GULCH AND HIGHLY MANGANIFEROUS. SILVER IS PRESUMED TO LIE IN THE CRYSTAL LATTICES OF GALENA AND JAMESONITE.
Comment (Location): SHAFT AND SURFACE WORKINGS REPRESENTING WESTERNMOST MINESITE OF CANDELARIA DISTRICT
Comment (Production): CUMULATIVE PRODUCTION UNKNOWN. SEVERAL THOUSAND TONS OF ORE SHIPPED BETWEEN 1948 - 1952 VALUED AT $35 - $75 PER TON. AVE. METAL CONTENT/TON = AU 0.5-0.6 OZ.; AG 8 - 12 OZ.; PB 8 - 12 %; SB 4 - 6 %; FEO 12 - 15 %; CU 0.5 %; ZN 0.5 %. IN 1956, THERE WAS SOME UNDERGROUND PRODUCTION, BUT ACTIVITY CEASED BEFORE 1961.
Comment (Deposit): VEIN ESSENTIALLY CONCORDANT WITH THE BEDS OF THE FOOTWALL
Comment (Workings): EXTENSIVE WORKINGS. VEIN HAS BEEN SLOPED CONTINUOUSLY ALONG STRIKE FOR 600 FEET OR MORE TO THE SURFACE. EXTENT OF MORE RECENT WORKINGS UNKNOWN
Comment (Geology): MOST FAVORABLE HORIZON FOR VEINS IS JUST ABOVE THE DIABLO GRIT. WEST OF MINE, 2 OR 3 VEINS LIE SIDE BY SIDE, SHOWING THAT FAVORABLE HORIZON IS NOT CONFINED TO SINGLE STRATUM, BUT COMPRISES SEVERAL HUNDRED FEET OF STRATA.
