Geologic setting

Geologic description

Small-scale placer mining was done on lower Rube Creek in the early 1900s. Gold is concentrated on clay-rich, false bedrock and in the overlying 2 to 3 feet of gravel. Overburden is a variable thickness of barren gravel and sand and two feet or more of muck. A report of platinum is not verified. The heavy mineral concentrates include an unusual amount of black garnet (Harrington, 1919).

Production and reserves

Workings or exploration Small-scale placer mining was done on lower Rube Creek in the early 1900s. In 1945 the U.S. Geological Survey sampled the placer to evaluate its radioactive mineral potential. The site of old placer workings could not be found at that time. Little mining was done after the stampede in the early 1900s.
Indication of production Yes; small

Additional comments

Stream gradient approximately 100 feet per mile in lower mile of creek.
