Comments
Comment (Reference): Primary Reference = Gassaway, 1935
Comment (Workings): Workings / Exploration = The beach areas had been prospected prior to 1935 (Gassaway). U.S. Bureau of Mines claim map shows no apparent activity after 1950.
Comment (Deposit): Model Name = Gold placer (Cox and Singer, 1986; model 39a).
Comment (Geology): Age = Quaternary
Comment (Exploration): Status = Inactive
Comment (Geology): Geologic Description = Black sands occur along the northeast coast and at the extreme north end of the island for a distance of approximately 10 miles (Gassaway, 1935). These sands commonly occur as thin surface crusts on the beaches near high-tide levels. Some crusts were also noted on local sand dunes. On the northern tip of the island a narrow strip of black sand about 6 inches thick and extending about 1/8 mile was noted. The presence of gold in the black sands was found to be very sporadic as indicated in panned samples taken by Gassaway.
