Stream gradient in the mining area is approximately 100 feet per mile.
Location: The Central Creek placer mine is in section 19, T. 20N., R. 7W., of the Kateel River Meridian. Coordinates are for the approximate center of placer ground. Cobb (1972, MF-386), location 10. Schmidt and Allegro (1988), location 283.
Geology: This placer gold deposit is located in the stream channel and benches along Central Creek. Bedrock along the creek is schist and limestone of early to mid-Paleozoic age. Depth to bedrock varies from 9 to 14 feet in the benches and from 1 to 5 feet in the stream bed. The gold is fine and flaky (Reed,1932).
Workings: Many shallow shafts were sunk in the 1930s to test for gold along the creek and some winter drift mining was done. Early miners shoveled gravel directly from the stream bed. During the winter of 1930-31, a line of drill holes at 50 foot spacing were put across the stream valley. Results indicated an average value of $0.64 per cubic yard (gold at $20.67/ounce). Additional drilling was planned for the summer of 1932 (Reed, 1932).
Age: Quaternary.
Production: Production through 1930 was approximately 145 ounces of fine, flaky gold (Schmidt and Allegro, 1988).
