|Location and accuracy||The occurrence is near the confluence of Trembley Creek and Kuyuktuvuk Creek about 1 1/2 miles west of the Dietrich River (NE1/4 sec. 19, T. 36 N., R. 10 W., of the Fairbanks Meridian). The location is accurate within a 1/2-mile radius.|
Geologic descriptionTwo claims were reported to have been located in 1963, and there is evidence of placer mining activity, principally along Kuyuktuvuk Creek (U.S. Bureau of Mines, 1973; Dillon, 1987). Country rocks in the area are shown by DeYoung (1978) to be principally Devonian limestone and siltstone, Pennsylvanian and Mississippian limestone, dolomite, shale, and conglomerate of the Lisburne Group and Kayak Shale, and Devonian Hunt Fork Shale. No other information is available on this occurrence.
