About the MRDS Data:

All mine locations were obtained from the USGS Mineral Resources Data System. The locations and other information in this database have not been verified for accuracy. It should be assumed that all mines are on private property.

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.

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.
