The Unnamed (south of King Salmon River) is a silver and gold 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 (Reference): Primary Reference = Clark and others, 1970 (OF 437)
Comment (Geology): Geologic Description = Clark and others (1970 [OF 437]) report analytical data for several rock samples collected over about 6,000 feet of this ridgecrest. The samples contain weakly to strongly anomalous concentrations of Ag (to 3 ppm), Au (to 0.7 ppm), As, B, Cu, Mo, and Hg. These samples were collected in a large area of hornfels. Clark and others (1970 [OF 438]) generally describe hornfels with anomalous metal contents as strongly limonite stained and cut by numerous small quartz veins rarely exceeding 1/8 inch in width. Some of the quartz veins carry minor amounts of arsenopyrite, and arsenopyrite is also locally disseminated in hornfels. Some scorodite and malachite are also locally present.
Comment (Workings): Workings / Exploration = Reconnaissance surface observation and sampling has taken place on this prospect.
Comment (Geology): Age = Late Cretaceous. Hornfels is developed in mid-Cretaceous clastic sedimentary rocks and is probably similar in age to hornfels at the Shotgun prospect (TA007). Intrusive rocks in the area of the Shotgun prospect are about 68 to 70 Ma in age.
Comment (Deposit): Model Name = Polymetallic veins? (Cox and Singer, 1986; model 22c)
Comment (Exploration): Status = Probably inactive
