The Unnamed (near Iron Creek) is a copper 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 = Cathcart, 1922
Comment (Workings): Workings / Exploration = This lode mineralization was exposed at the surface by a small open cut.
Comment (Deposit): Model Name = Copper sulfides and malachite in quartz-rich rock.
Comment (Geology): Geologic Description = A 3-foot-wide zone of silicified marble contains copper sulfide and some malachite stain (Cathcart, 1922). A nearby calcite vein is cut by quartz veinlets and pyrite is present in both. Bedrock is part of a lower Paleozoic metasedimentary assemblage (Till and others, 1986). Also see other copper prospects in the Iron Creek area such as SO124 and SO125.
Comment (Exploration): Status = Inactive
