| Location and accuracy | This placer mine is at an elevation of approximately 1,100 feet in a small drainage basin downstream from Silverbow Basin on Gold Creek. It is in the NW1/4SE1/4 section 18, T. 41 S., R. 68 E. of the Copper River Meridian. The location is accurate. |
Geologic descriptionThe Little Basin placer was discovered in 1881 and had a 300-foot drainage tunnel. The placer was formed by the erosion of the adjacent north ore body of the Alaska-Juneau Mine. The deposit is divided into 2 sections; the lower section is alluvium and the upper section is colluvium (Spencer, 1906). Approximately 75,000 cubic yards were mined, including 52,000 cubic yards from the upper section and 23,000 cubic yards from the lower section. The mine produced at least 2,400 ounces of gold by 1889 (Redman and others, 1989). | |
