|Location and accuracy||This occurrence is at an elevation of about 600 feet in the headwaters of an unnamed tributary of Duck Creek, about 1.4 miles south of Clem Mountain. The map site is in section 34, T. 7 N., R. 13 W., of the Kateel River Meridian. Cobb, 1972 (MF-389), location 21.|
Geologic descriptionThis occurrence consists of Upper Cretaceous-Lower Tertiary granite that may contain uranium-bearing minerals. Uranothorianite was found in a concentrate sample of stream gravels (Gault and others, 1953). The sample contained 0.106% eU.
