Location: Nome Creek is a productive placer area of approximately 40 square miles extending from Moose Creek to Sourdough Creek. Most mining was from about 1 km above the junction with Summer Creek to the junction with Moose Creek. Some mining was done on Summer Creek, just above its mouth. The location is the approximate center of the mined area and about 7 miles E-SE of Table Top Mountain. Nome Creek is now a recreational panning area that is accessible from the Steese Highway at mile marker 53.7 via a two-wheel drive gravel road that runs 6 miles to Nome Creek (Lampright, 1996).
Geology: Headwaters of Nome Creek are in the Mt. Prindle area where a small lower Tertiary pluton intrude Paleozoic and (or) Precambrian schist (Cobb, 1973, p. 174, [B 1374]). The paystreak is 2 to 4 feet thick overlain by about 15 feet of gravel (Ellsworth and Parker, 1911, p. 165). Concentrates contain gold, cassiterite, monazite, topaz and tourmaline (Wedow and others, 1954, p. 8). Gold was discovered in 1910 (Ellsworth and Parker, 1911). Dredging occurred in 1926 to 1931, 1939 to 1940, and 1946 (Cobb, 1976, p. 50, [OFR 76-633]). Mining occurred during several seasons between 1960 and 1982 (Menzie and others, 1983). Most of the mining has been about 1 km above the junction with Sumner Creek to the junction with Moose Creek, a distance of about 10 km. Some work was also done on Sumner Creek, just above its junction with Nome Creek. Nome Creek is now a state recreational mining site limited to non-mechanized operations.

Production: There are no data on production but the workings suggest that the total is substantial (Menzie and others, 1983, p. 49).
