The Unnamed (near Cape Resurrection) is a lead, copper, silver, 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.

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 = Cretaceous or younger; breccia zone in Cretaceous basalt.
Comment (Workings): Workings / Exploration = A hand sample contained 3 PPM silver, 70 ppm cadmium, 1500 ppm copper, 3000 ppm lead, and 9,200 PPM Zn (Tysdal, 1978).
Comment (Reference): Primary Reference = Tysdal, 1978
Comment (Deposit): Model Name = Cyprus massive sulfide (Cox and Singer, 1986; model 24a).
Comment (Geology): Geologic Description = The host rock is Upper Cretaceous sheeted basalt of the Valdez Group that has been sheared and brecciated (Tysdal, 1978). The shear and breccia zone is 0.6 meters wide and contains quartz, pyrite, chalcopyrite, and galena. Analysis showed 3 ppm silver, 70 ppm cadmium, 1,500 ppm copper, 3,000 ppm lead, and 9,200 ppm zinc. Tysdal (1978) considers this occurrence to be a volcanogenic massive sulfide deposit.
Comment (Exploration): Status = Inactive
Comment (Commodity): Ore Material = unknown zinc mineral
Comment (Commodity): Ore Material = unknown zinc mineral
