The Unnamed (in divide at head of Quartz Creek) is a lead, silver, and zinc 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 (Commodity): Ore Material = argentiferous galena
Comment (Deposit): Model Name = Sulfides in altered andesite.
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 (Exploration): Status = Inactive
Comment (Geology): Geologic Description = This occurrence is located adjacent to the mid-Cretaceous Quartz Creek pluton, a hook-shaped, quartz monzonite body. The pluton is surrounded by a N 15 W-trending alteration zone about 18 miles long and 2 to 5 miles wide. The alteration zone is in Jurassic-Cretaceous andesitic volcanic rocks, and is marked by carbonate-quartz replacement, and tourmaline. Fine-grained dikes of varying composition cut the andesites near the pluton. Dikes near the Quartz Creek pluton are locally mineralized. This occurrence is a sulfide-bearing, oxidized carbonate zone in altered andesite. A composite grab sample contained: 200 ppm Ag (5.8 ounces Ag per ton), greater than 500 ppm Cd, 200 ppm Cu, greater than 2% Pb, and greater than 1% Zn (Miller and Elliott, 1969, location 27).
Comment (Geology): Age = Late Cretaceous.
Comment (Reference): Primary Reference = Miller and Elliott, 1969
Comment (Workings): Workings / Exploration = The area has been mapped by the U.S. Geological Survey and examined by various exploration companies.
