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 = Killeen and Mertie, 1951.
Comment (Geology): Geologic Description = Quartz vein containing small lenses and stringers of stibnite and possibly gold. The quartz vein is hosted in middle Paleozoic or older quartz schist, mica schist and marble of Yukon Crystalline terrane. Grab samples contained up to 28 percent Sb (Killeen and Mertie, 1951, Nokleberg and others, 1987).
Comment (Deposit): Other Comments = Includes references to Sb lode on Sourdough Creek.
Comment (Deposit): Model Name = Low-sulfide Au-quartz vein (Cox and Singer, 1986; model 39a)
Comment (Workings): Workings / Exploration = Explored by several short adits.
Comment (Exploration): Status = Inactive
