The Tuluksak River is a gold 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 (Workings): Workings / Exploration = Dredge tailings at least 3 miles long and up to 0.4 mile wide are present along the river. Ditches, flume, airstrip, buildings, and power line are shown on the USGS Bethel D-3 1:63,360-scale topographic map (1951/1971 edition).
Comment (Geology): Age = Quaternary.
Comment (Reference): Primary Reference = Hoare and Cobb, 1977
Comment (Deposit): Model Name = Placer Au-PGE (Cox and Singer, 1986; model 39a).
Comment (Geology): Geologic Description = Extensive dredging has taken place onTuluksak River for about 3 miles upstream of the mouth of Slate Creek. The dredged area is up to 0.4 mile wide and it continues upstream into the Russian Mission quadrangle. Mining on this river started as early as 1909 and continued until 1964 (Hoare and Cobb, 1977). Some platinum was produced along with the gold. There have been some attempts to renew placer mining without apparent success. Copper mineralization in andesitic bedrock was dredged up locally (BH013). A significant part of the bedrock in the drainage is hornfels in Jurassic volcanic rocks surrounding a mid-Cretaceous pluton (Box and others, 1993).
