The Unnamed (near Kelsall River) is a copper and zinc 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 = No workings are reported and very little information is available. The cursory description by Eakin (1919) appears to have been replicated in subsequent references. The claim(s) is apparently long inactive.
Comment (Geology): Geologic Description = Eakin (1919) describes the prospect as a vein a few inches wide that contains pyrite, pyrrhotite, chalcopyrite, and sphalerite in quartz gangue. The main portion of the vein is chalcopyrite and pyrrhotite; sphalerite occurs along the vein margins. No additional detail is provided in subsequent references to this prospect (Cobb, 1972 [MF 424]; Cobb, 1978 [OF 78-316]; and Berg, 1984).
Comment (Reference): Primary Reference = Eakin, 1919
Comment (Deposit): Model Name = Very little information, but apparently a polymetallic quartz-sulfide vein (Cox and Singer, 1986; model 22c).
Comment (Exploration): Status = Inactive
