Location: Along unnamed eastward flowing stream on west side of Unakwik Inlet across from Miners Bay. Accurate within 1 mile. This is locality P-32 of Janson and others (1984) and locality P-33 of Hoekzema and Fechner (1986).
Geology: Jansons and others (1984) reported fine gold disseminated in poorly washed fluvial glacial gravels. An alluvium sample contained 0.0021 oz Au/cubic yard. The gravels contain boulders up to 5 ft in diameter and moderate clay hardpan. Bedrock in the area is metasedimentary rocks of the Late Cretaceous Valdez Group.
Workings: No workings reported. An alluvium sample contained 0.0021 oz Au/cubic yard. Grade is likely low, but local concentrations of economic significance may exist. Moderate potential for small mining operation (Jansons and others, 1984).
