The Unnamed (on Quartz Creek) is a lead and silver 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 = Galena in calcite vein.
Comment (Exploration): Status = Inactive
Comment (Geology): Age = Late Cretaceous.
Comment (Deposit): Other Comments = This site is one of numerous occurrences of argentiferous galena, sphalerite, pyrite and arsenopyrite in an 18-mile-long, 2- to 5-mile-wide zone of altered andesite surrounding the Quartz Creek quartz monzonite pluton. The altered zone trends N 15 W, across the drainage basins of Quartz Creek and the Kiwalik River, parallel to prominent lineaments in the area.
Comment (Geology): Geologic Description = This occurrence consists of a calcite veinlet containing minor galena. The veinlet cuts altered Jurassic-Cretaceous andesite near its contact with quartz monzonite of the Cretaceous Quartz Creek pluton. A grab sample from this location contained: 300 ppm Pb and a trace Ag (Miller and Elliott, 1969).
Comment (Reference): Primary Reference = Miller and Elliott, 1969
Comment (Workings): Workings / Exploration = The area has been mapped and examined by the U.S. Geological Survey and various exploration companies.
Comment (Commodity): Ore Material = argentiferous galena
