The Unnamed (head of Slide Creek) is a zinc, silver, 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 (Deposit): Model Name = Kuroko massive sulfide (Cox and Singer, 1986; model 28a)
Comment (Geology): Geologic Description = The country rocks at this prospect are the Lower Mississippian to Middle Devonian Totatlanika Schist, composed predominantly of mafic and felsic metavolcanic and metavolcaniclastic rocks (Wilson and others, 1998). The deposit consists of massive-sulfide lenses in schist. The lenses are chiefly galena and sphalerite, accompanied by quartz and sericite. The footwall schist is altered to chlorite and sericite.
Comment (Exploration): Status = Active?
Comment (Geology): Age = Mineralization was probably syngenetic with the Lower Mississippian to Middle Devonian host rocks.
Comment (Workings): Workings / Exploration = There reportedly has been surface exploration and possibly limited drilling.
