Geologic setting

Geologic description

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.

Production and reserves

Workings or exploration 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).
Indication of production None
