The Unnamed (east of Sitkagi Bluffs) 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 (Workings): Workings / Exploration = This segment of the Yakutat beach placers was sampled in at least three locations by Reimnitz and Plafker (1976, samples numbers 33, 34, and 35). All three sample localities had detectable gold; samples 33 and 35, respectively, contained 0.890 and 0.030 ppm of gold. The gold was determined by atomic absorption; some of it, therefore, may be in combined rather than free state. There are no workings.
Comment (Exploration): Status = Inactive
Comment (Geology): Age = Holocene
Comment (Commodity): Ore Material = Gold (native)
Comment (Production): Production Notes = None known.
Comment (Reference): Primary Reference = Reimnitz and Plafker, 1976.
Comment (Deposit): Model Name = Placer; modern beach, largely derived from glacial-fluvial material brought down by Malaspina Glacier.
Comment (Deposit): Other Comments = the entire length of the beach placer is in Wrangell-St. Elias National Park and Preserve.
Comment (Geology): Geologic Description = The locally auriferous beach between Sitkagi Bluffs and Point Manby was produced by wave and long shore action on glacial moraine and outwash from the Malaspina Glacier and on alluvium brought down by the high energy streams that drain the glacier. The ultimate source of gold is in the upland hard rock terrane, but intermediate sources exist, as in the glacial deposits and the Yakutat Formation (Reimnitz and Plafker, 1976).? Reimnitz and Plafker (1976) also found gold at the three localities that they sampled along the beach, including a maximum of 0.890 ppm gold in sample number 33.
