Geologic setting

Geologic description

This prospect consists of Upper Cretaceous or Lower Tertiary granite which may contain uranium-bearing minerals. A sample of stream-gravel concentrate contained 0.033% eU (Gault and others, 1953).
Geologic map unit (-161.462664960947, 65.6793289693448)
Mineral deposit model Radioactive minerals in stream sediments.

Production and reserves

Workings or exploration In 1947 the U.S. Geological Survey sampled the stream sediments to evaluate their radioactive mineral content (Gault and others, 1953).
Indication of production Undetermined

Additional comments

Stream falls approximately 400 feet in headwater mile.
