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 (Location): NEAR HEAD OF SULTAN BASIN ON NORTH SIDE OF NORTH FORK SULTAN RIVER
Comment (Deposit): 2-10 FT WIDE VEIN ALONG SHEAR ZONE. THERE MAY BE TWO PHASES OF MINERALIZATION, A MAGMATIC SULFIDE PHASE DURING CRYSTALLIZATION OF THE ULTRAMAFIC ROCKS WHICH CONCENTRATED SOME OR ALL CU AND NI AND A HYDROTHERMAL PHASE POSSIBLY ASSOCIATED WITH THE INDEX BATHOLITH DURING WHICH THE REMAINING COMMODITIES AND POSSIBLY MORE COPPER WERE CONCENTRATED.
Comment (Workings): OPEN CUTS, ADITS
Comment (Geology): THE DISTRICT CONSISTS OF ACCRETED METASEDIMENTARY ROCKS INTRUDED BY GRANITIC ROCKS AND OVERLAIN BY MARINE STRATA AND YOUNGER VOLCANIC ROCKS
Comment (Commodity): CHROMITE HAS BEEN REPORTED, BUT APPARENTLY NOT VERIFIED
