Location and accuracy Nugget Creek is a small south tributary of the Seventymile River. Gold-bearing placer deposits were mainly found along the lower mile of Nugget Creek. The coordinates are about one-half mile upstream of the mouth of the creek, in section 28, T. 2 N., R. 27 E., of the Fairbanks Meridian. The location is accurate. Nugget Creek is locality 18 (locality 19 on the map) of Cobb (1972 [MF-393]), locality 46 of Eberlein and others (1977), and locality 4 of Burleigh and Lear (1994).

Geologic setting

Geologic description

The rocks on lower Nugget Creek are Paleozoic gneiss, schist, quartzite, amphibolite, and feldspathic gneiss (Clark and Foster, 1969; Foster, 1976). Upper Nugget Creek is crossed by strands of the Tintina Fault; the rocks consist of Permian quartzite and argillite that have been intruded by Tertiary to Mesozoic granitic to ultramafic plutonic rocks; Tertiary felsic volcanic rocks are also present (Foster, 1976).
Gold placers are found mainly along the lower mile of the Nugget Creek (Mertie, 1938). The gravel has an average thickness of 4 feet; the pay was found over a width of 20 feet. (Prindle, 1905). Gold in Nugget Creek occurs as plates as much as one-quarter of an inch in diameter (Prindle, 1905). Placer concentrates contain minor black sand (magnetite?) and garnets (Prindle, 1905). An assay of placer gold from Nugget Creek contains 851 parts of gold and 143 parts of silver per thousand (Mertie, 1942).
Two men were working on Nugget Creek in 1903 (Prindle, 1905). Mining on Nugget Creek was sporadically reported from 1908 to 1936. There has been placer gold production on the Seventymile River (see EA025) downstream of Nugget Creek.
