The Unnamed (near summit of White Mountain) is a copper and mercury 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 (Deposit): Model Name = Polymetallic vein (?) (Cox and Singer, 1986; model 22c).
Comment (Geology): Geologic Description = This unnamed occurrence is a cinnabar-bearing breccia in a diabase dike that intrudes an unnamed algal limestone, a subdivision of the Nixon Fork subterrane (Gilbert, 1981; Wilson and others, 1998). The host dike trends east-west and dips steeply into the hillside. One sample of cinnabar-bearing breccia contained 214 ppm copper; mercury was not analyzed.
Comment (Reference): Primary Reference = Gilbert, 1981
Comment (Workings): Workings / Exploration = W.G. Gilbert found the occurrence during geologic mapping for the Alaska Division of Geological and Geophysical Surveys in 1979 (Gilbert, 1981). One sample of cinnabar-bearing breccia contained 214 ppm copper; mercury was not analyzed.
Comment (Exploration): Status = Inactive
