|Location and accuracy||Beaver Creek is a southeast-flowing tributary of Poorman Creek and is about 5 miles long. This site corresponds to location 31 of Cobb (1972 [MF405]) and is located in section 21, T. 16 S., R. 16 E., Kateel River Meridian. The location is accurate within 1 mile.|
Geologic descriptionThe bedrock under Beaver Creek is probably weathered basaltic greenstone (Eberlein and others, 1977). Placer gold was initially discovered in 1930 at the bottom of a 60-foot shaft. The gold-bearing gravel was mined from 1930 to 1932, and the discoverers may have removed as much as 315 ounces from a drift at the bottom of the shaft (Mertie, 1936). The gold was found on bedrock, and there was very little gravel. Since continuity was not found, mining stopped in 1932 (Mertie, 1936).
