Location: Located along both sides of Monitis Creek, 600 m above junction with Kiruktagiak River. Known to within one mile
Geology: The phosphate occurrences are confined to the black chert and shale member of the Alapah Limestone. Interbedded phosphorite and phosphate rock occur in sections up to 11.3 m thick. The phosphate-bearing mineral consists of fluorapatite, which is concentrated in oolites, pellets, and matrix. Purple fluorite occurs locally. The phosphatic rocks can be traced for 1.5 km along strike.
Workings: Individual phosphorites up to 0.6 m thick contain up to 330% P2O5. One 6.7 m-thick section averaged 23% P2O5. Samples also contained up to 2,000 ppm V, and 119 ppm U.
Age: Mississippian

Commodities (Major) - P; (Minor) - U, V
Development Status: No
Deposit Model: Bedded phosphorite
