Geologic setting

Geologic description

Spring Creek heads in the Late Cretaceous Granite Mountain monzonite pluton and flows across its contact with Jurassic-Cretaceous andesitic volcanic rocks. Placer gold reportedly was mined about a mile below a hot spring. Depth to bedrock at the mouth of creek is about 10 feet. Some of the bench placer ground is 12 feet deep.

Production and reserves

Workings or exploration In 1947 the U.S. Geological Survey sampled the placer to evaluate its radioactive mineral potential. There was little sign of active mining at that time.
Indication of production Undetermined
