|Location and accuracy||Cobb (1972, MF-413), loc. 93. The coordinates given are for a bench north of Nome Creek, east of the mouth of Ophir Creek, however, most of the mining on Nome Creek took place upstream, in the Circle quadrangle (ARDF no. CI041).|
Geologic descriptionCoarse placer gold, in 2 to 4 feet of pay gravel, was first found near the mouth of Ophir Creek in 1910 (Ellsworth and Parker, 1911, p. 165; Ellsworth, 1912). However, most of the mining and all of the dredging took place upstream in the Circle quadrangle (ARDF no. CI041).
|Geologic map unit||(-147.044478502328, 65.3665908133738)|
|Mineral deposit model||Placer gold deposit (Cox and Singer, 1986; model 39a).|
|Mineral deposit model number||39a|
|Workings or exploration||Some placer mining occurred prior to WWI in lower Nome Creek. The upper portion of Nome Creek lies within the Circle quadrangle (ARDF no. CI041), and has been actively mined up until at least 1982 (Menzie and others, 1983).|
|Indication of production||Yes; small|
|Production notes||Mining reported before WWI, but no record of amount of production.|
