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): TEN CLAIMS AT FIVE LOCATIONS ON THE NIBLACK ISLANDS, ERNEST SOUND, WERE STAKED FOR CU IN 1956; APPARENTLY NOT ACTIVE SINCE (U.S. BUREAU OF MINES, 1980). BRIEF EXAMINATION BY THE USGS IN 1979 DID NOT REVEAL ANY OBVIOUS SIGNS OF MINERAL DEPOSITS (GRYBECK, BERG, AND KARL, 1984, LOCALITY 79). ROCKS IN THE VICINITY CONSIST LARGELY OF MIGMATITE AND GRANITE (BREW AND OTHERS, 1984).
Comment (Production): NONE
Comment (Exploration): Status = Probably inactive
