Location: Location is at west end of Ivotuk Hills, 100 m from Otuk Creek. Known to within one mile.
Geology: 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.
Workings: Geochemical analysis showed the phosphatic limestone contained 30.7% P205, 0.11% V, and 150 ppm U.
Commodities (Major) - P, U, V
Development Status: No
Deposit Model: Bedded phosphorite
