The Unnamed (east-northeast of Danger Pass) is a zinc, antimony, 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 (Workings): Workings / Exploration = Work restricted to limited surface sampling during geologic mapping by USGS in the late 1970s.

Comment (Reference): Primary Reference = Grybeck and Nelson, 1981

Comment (Geology): Geologic Description = This occurrence consists of a grab sample of thin, locally copper-stained, quartz veins that cut orange-weathering marble of the Devonian-Siluran Skagit Limestone (Nelson and Grybeck, 1980; Grybeck and Nelson, 1981). Selected samples contain up to 70 ppm Ag, 1 percent Cu, 1 percent Sb, and 2000 ppm Zn. The veins apparently are of only local extent.

Comment (Deposit): Model Name = Polymetallic veins ? (Cox and Singer, 1986; model 22c)

Comment (Deposit): Other Comments = Located within Gates of the Arctic National Park.

Comment (Exploration): Status = Inactive
