The Unnamed (north of Kiwalik River) is a gold 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 (Geology): Geologic Description = This occurrence is located adjacent to the mid-Cretaceous Quartz Creek quartz monzonite, a hook-shaped pluton that intrudes Jurassic-Cretaceous andesitic volcanic rocks. The pluton is surrounded by a N 15 W-trending alteration zone about 18 miles long and 2 to 5 miles wide. The altered volcanic rocks are marked by carbonate-quartz replacement, and possibly by tourmaline. A sample of gossan at the contact between quartz monzonite and andesite contained 1 ppm Au, 3,000 ppm As, 300 ppm Cu and 150 ppm Pb (Miller and Elliott, 1969, location 37).
Comment (Workings): Workings / Exploration = The area has been mapped by the U.S. Geological Survey and examined by various exploration companies.
Comment (Reference): Primary Reference = Miller and Elliott, 1969
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.
Comment (Geology): Age = Mid-Cretaceous or younger.
Comment (Deposit): Model Name = Sulfides in altered andesite.
Comment (Exploration): Status = Inactive
