Unnamed (east of Walker Lake)

The Unnamed (east of Walker Lake) is a molybdenum, lead, copper, and silver mine located in Alaska.

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 (Geology): Age = Devonian, based on the age of the host rocks.

Comment (Reference): Primary Reference = Garland and others, 1975 (ADGGS OFR 66)

Comment (Deposit): Model Name = Kuroko massive sulfide (Cox and Singer, 1986; model 28a)

Comment (Geology): Geologic Description = This occurrence consists of a 100-foot-thick section of Mn-stained graphitic schist, from which grab samples assayed up to 5 ppm Ag, 500 ppm Cu, 70 ppm Mo, and 70 ppm Pb. The schist is Devonian in age (Grybeck and Nelson, 1981). Grybeck and Nelson (1981) note that the occurrence is probably similar to volcanogenic massive sulfide deposits elsewhere in the Survey Pass quadrangle.

Comment (Exploration): Status = Inactive
