|Location and accuracy||Goldbottom Creek is a north tributary to Niukluk River that, in its upper part, is 6 miles west of Ophir Creek. Only its upper parts (including its headwater triburtaries Virginia and Russel Creeks) are within the Bendeleben quadrangle. Most of the placer gold mining on Goldbottom Creek took place to the south in the Solomon quadrangle. This location is very approximate; probably located within one mile. It is locality 76 of Cobb (1972; MF 417; 1975; OFR 75-429).|
Geologic descriptionCollier and others (1908) report that 3 feet of schist gravel (covered by 2 feet of sod and muck) from a claim near the head of Goldbottom Creek., was shovelled into a sluice and fine, angular gold was recovered. This description could indicate a location farther up Goldbottom Creek (perhaps a headwater tributary) than that identified here. Gold-bearing bedrock is known at two localities (BN104 and BN125) on the divide at the head of Goldbottom Creek. Bedrock in the area is metasedimentary schist and marble of a Lower Paleozoic assemblage (Till and others, 1986).

|Workings or exploration||Surface placer mine workings, perhaps only the result of hand operations, have been reported here. Much more extensive placer mining, including dredging, has taken place lower on Goldbottom Creek (primarily in the Solomon quadrangle).|
