The Ivotuk Hills is a uranium, vanadium, and 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.

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 = Geochemical analysis showed the phosphatic limestone contained 30.7% P205, 0.11% V, and 150 ppm U.
Comment (Deposit): Model Name = Bedded phosphorite
Comment (Geology): Geologic Description = A 1.2 m-thick sequence of interbedded phosphatic pelletal limestone and shale of the Otuk Formation is exposed on the north side of the Ivotuk Hills. The limestone beds are lensey, average approximately 78 mm thick, and comprise up to 50% of the 1.2 m-thick section. This occurrence is unique because rocks with such high phosphate content are not common in the Otuk Formation. The Lisburne Ridge phosphate occurrence, 47 km to the northwest may be an extension of the Ivotuk phosphorites.
Comment (Exploration): Status = Inactive
