Anaktuvuk River

The Anaktuvuk River is a phosphorus-phosphates 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 (Deposit): Model Name = Bedded phosphorite

Comment (Geology): Geologic Description = Ocurrence consists of phosphatic, uranifereous(?) pelletal rock from the Alapah Limestone of the Mississippian and Pennsylvanian Lisburne Group. Pelletal phosphate with quartz, purple fluorite and carbonaceous matter, occurs in a calcite matrix in the black shale and chert member of the Alapah.

Comment (Workings): Workings / Exploration = Samples of phosphatic, uranifereous(?) pelletal rock contain 15% and 21.4% P2O5. Highest radioactivity was 0.014% eU. Field samples No. 50AB076 and No. 50AB078
