Location: Kigezruk Creek is a 2.5 mile-long, south-southwest flowing stream whose mouth is on the Bering Sea coast about 7 miles east of Tin City and 2.2 miles west of York. It is located at the major fork in the creek, about 0.6 mile upstream from the mouth. This is locality 34 of Cobb and Sainsbury (1972). Cobb (1975) summarized relevant references under the name 'Kigezruk Cr.'.
Geology: Bedrock in the drainage is a slaty metapelitic and metasandstone sequence of unknown but probable Paleozoic age that is locally intruded by altered mafic bodies (Sainsbury, 1972). A trace and 0.01 pounds of tin per cubic yard were found in heavy mineral concentrates from two USBM churn-drill holes (Mulligan, 1959, p. 21). Heavy minerals that were identified included pyrite, magnetite, ilmenite, and tourmaline; cassiterite was not identified. Overburden is not present and the stream gravels over bedrock are only 3 to 4.5 feet thick. Gold has been reported from this creek but its presence was not confirmed by USBM churn-drilling.
Workings: Two USBM churn drill holes have been completed here.
Age: Quaternary
