The Aichilik River is a ree 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 (Exploration): Status = Inactive
Comment (Commodity): Ore Material = Yttrium
Comment (Geology): Geologic Description = High yttrium (300 ppm) and ytterbium (15 ppm) in sample of efflorescent salt that is mainly aluminum sulfate. Efflorescent salts coat outcrops of Kingak Shale and accumulate along the margins of ephemeral pools at the foot of cut banks.
Comment (Deposit): Other Comments = Sulfosalts similar to those described here are present in outcrops of the Hue Shale, Gamma-ray, and Inoceramus zones, Cretaceous units that lie above the Kingak Shale. Sulfosalt blooms similar to those described here are more abundant in these units than in the Kingak Shale. The Kingak Shale can be difficult to descriminate from these units, especially where these shales are structurally complex and poorly exposed. (J.S. Kelley, personal observation)
Comment (Deposit): Model Name = Sedimentary
Comment (Commodity): Ore Material = Ytterbium
Comment (Commodity): Ore Material = Yttrium
Comment (Geology): Age = Host rock is Jurassic and Early Cretaceous age
Comment (Geology): Age = Host rock is Jurassic and Early Cretaceous age
