The Unnamed (near Igloo Creek) is a tin 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 = Sainsbury, 1972
Comment (Geology): Age = May be Late Cretaceous, the age of other tin-bearing mineralized systems of western Seward Peninsula.
Comment (Geology): Geologic Description = Sainsbury (1972) notes the occurrence of tactite rubble and outcrop on this ridge. The mapped bedrock assemblage in this area is chlorite-epidote-amphibole schist with some intercalated metacarbonate rocks and local metamorphosed mafic intrusive bodies (Sainsbury, 1972). Partial results of a spectrographic analysis reported by Sainsbury (1972, p. 3) indicate that tactite here can contain greater than 1,000 ppm tin, 1,000 ppm beryllium, and greater than 1,000 ppm bismuth. No other data are available.
Comment (Deposit): Other Comments = A 1982 reconnaissance traverse on this ridge did not relocate this occurrence (Hudson, 1983).
Comment (Deposit): Model Name = Tin-bearing skarn (Cox and Singer, 1986; model 14b)
Comment (Workings): Workings / Exploration = No prospecting activities are known to have taken place at this location.
Comment (Exploration): Status = Inactive
