|Location and accuracy||This occurrence is at the head of Muck Creek, an informally named, north-flowing tributary to Hunter Creek. The map site is in section 14, T. 4 N., R. 14 W., of the Kateel River Meridian. Cobb, 1972 (MF-389), location 25.|
Geologic descriptionThe Muck Creek area is underlain by Upper Cretaceous granitic rocks that may contain uranium-bearing minerals (Gault and others, 1953). Two pan-concentrate samples of stream gravels contained 0.125 percent and 0.16 percent equivalent uranium. Heavy minerals from the concentrate include garnet, hornblende, augite, sphene, zircon, epidote, apatite, scheelite, powellite, ilmenite, hematite, limonite, magnetite, uranothorianite, and pyrite.
