Location: The headwaters of Boulder Creek are in the Nome C-3 quadrangle; about 3.5 miles long, it flows southeasterly into Sinuk River in the Nome C-2 quadrangle. A placer gold deposit extends for about 2 miles along the creek. The location is the approximate mid-point of the auriferous section about at the boundary of the C-2 and C-3 quadrangles. This is locality 60 of Cobb (1972 [MF 463], 1978 [OFR 78-93]).
Geology: There is no specific information on this placer deposit. Collier and others (1908, p. 216-217) reported mining in 1902-03. Later claim activity was reported by Heiner and Porter (1972, Kardex site Kx 52-90) and active claims were reported as recently as 1981-82 (Alaska Division Geological and Geophysical Surveys, 1982). Bedrock in the Boulder Creek drainage is chloritic and graphitic schist (Sainsbury and others, 1972 [OFR 72-322]).
Workings: A placer deposit in Boulder Creek was discovered early in the history of the Nome district and was mined in 1902-03 (Collier and others, 1908). Claim activity was reported in 1929; claims may have been patented as U.S. Mineral Survey No. 841 (Heiner and Porter, 1972, Karex site Kx 52-90). Further claim activity was reported as recently as 1981-82 (Alaska Division of Geological and Geophysical Surveys, 1982).
