Geologic information

Identification information

Deposit ID 10308731
Record type Site
Current site name Ishut Creek

Geographic coordinates

Geographic coordinates: -167.61542, 65.56326 (WGS84)
Relative position Ishut Creek is a major, south-flowing headwater tributary to the Anikovik River; their confluence is about 4 miles upstream from the mouth of the Anikovik River at York on the Bering Sea. This locality, where 2 USBM churn-drill holes contained trace amounts of scheelite, is about 2.5 miles further upstream on Ishut Creek than locality 41 of Cobb and Sainsbury (1972). Cobb (1975) summarized relevant references under the name 'Ishut Cr.'.

Comments on the geologic information

  • Geologic Description = Bedrock in the drainage is a slaty metapelitic and metasandstone sequence of unknown but probable Paleozoic age locally intruded by altered mafic bodies (Sainsbury, 1972). Heavy mineral concentrate from two USBM churn-drill holes contained pyrite, limonite psuedomorphs after pyrite, magnetite, apatite, tourmaline, zircon, and traces of scheelite (Mulligan, 1959, p. 19). Three churn-drill holes on lower Ishut Creek (about 0.3 miles upstream from the mouth) contained heavy mineral concentrates with pyrite, limonite psuedomorphs after pyrite, augite, ankerite and zircon. A trace of tin was detected but tin-bearing minerals were not identified (Mulligan, 1959, p. 18-19).

Mining district

District name Port Clarence

Comments on the workings information

  • Workings / Exploration = A total of five churn-drill holes were completed by the USBM on Ishut Creek in 1957 (Mulligan, 1959). Two of these were at the location of this occurrence and three were about 2.5 miles downstream (about 0.3 miles upstream from the mouth of Ishut Creek on Anikovik River).
