The Unnamed (head of Kansas Creek) is a zinc, antimony, and lead 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 = Joesting, 1943
Comment (Workings): Workings / Exploration = Only surface workings. Samples contain as much as 63% antimony (Joesting, 1943).
Comment (Deposit): Model Name = Simple Sb (Cox and Singer, 1986; model 27d)
Comment (Exploration): Status = Inactive
Comment (Geology): Geologic Description = This prospect is in the Lower Paleozoic or possibly Late Precambrian Birch Creek Schist, which consists of quartz-sericite schist, quartzite, and a few interbeds of massive marble (Wilson and others, 1998). Lower Tertiary and Upper Cretaceous granites intrude the metasedimentary rocks less than one mile to the south. The deposit consists of quartz lenses containing stibnite, minor galena, and sphalerite. The lenses are up to 6 feet thick and trend northeast. Samples contain as much as 63% antimony (Joesting, 1943).
Comment (Geology): Age = Probably Late Cretaceous or younger, assuming deposit is related to nearby granitic intrusive rocks.
