| 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). |
