The Unnamed (near Slate Creek) is a 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 (Geology): Age = Cretaceous Mineralization postdates regional mid-Cretaceous metamorphism. The host dikes may be Cretaceous in age like many felsic intrusive rocks in the Kigluaik Mountains to the north or possibly younger.
Comment (Reference): Primary Reference = Chapin, 1914
Comment (Workings): Workings / Exploration = A small surface open cut was used to explore this prospect in 1913 (Chapin, 1914).
Comment (Exploration): Status = Probably inactive
Comment (Geology): Geologic Description = Greenstone is cut by altered, fine-grained, felsic (?) dikes in this area; the feldspars in the dikes has been replaced by sericite and kaolin. A 3-foot-wide altered dike contains ferruginous calcite in fracture fillings and replacements that are in turn cut by quartz-calcite veinlets; free gold has been panned from crushed vein material (Chapin, 1914). Another 10-feet-wide dike nearby contains quartz, epidote, chlorite, albite, calcite, and tremolite(?). The greenstone host rock is completely recrystallized and contains hornblende, chlorite, epidote, garnet, pyrite, albite, rutile and sphene. Bedrock in this area is mostly part of a lower Paleozoic metasedimentary assemblage (Till and others, 1986).
Comment (Deposit): Model Name = Auriferous carbonate and quartz-carbonate veins and replacements in felsic (?) dikes.
Comment (Geology): Age = Host dikes may be Cretaceous.
