Stream gradient approximately 100 feet per mile in lower mile of creek.
Location: This placer mine is on lower Rube Creek in section 35, T. 1 S., R. 12 W., of the Kateel River Meridian. Cobb, 1972 (MF-389), location 38.
Geology: Small-scale placer mining was done on lower Rube Creek in the early 1900's. 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).
Workings: Small-scale placer mining was done on lower Rube Creek in the early 1900's. 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 1900's.
Age: Quaternary.
