Location and accuracy Gold Run is a small west tributary of Slate Creek. The location of placer gold mining is not reported; the coordinates are near an old cabin about 2.5 miles upstream of the mouth of the creek, in section 6, T. 4 S., R. 25 E., of the Fairbanks Meridian. Gold Run is locality 25 of Burleigh and Lear (1994), locality 32 of Eberlein and others (1977), and locality 42 of Cobb (1972 [MF-393]).

Geologic setting

Geologic description

The rocks along Gold Run are Paleozoic quartzite and micaceous, schistose quartzite (Prindle, 1913). At the head of Gold Run, there is a northeast-trending fault that separates metamorphic rocks to the southeast from Tertiary to Cretaceous conglomerate to the northwest (Foster, 1976). Just southeast of the fault, there is a small area of Tertiary to Mesozoic basalt or gabbro; northwest of the fault the sedimentary rocks have been intruded by Tertiary felsic volcanic rocks (Foster, 1976). Foster and Clark (1970) suggested the Tertiary(?) bedrock is the source for placer gold in Gold Run. The depth of the gravels is about 12 feet, and quartz is abundant (Brooks, 1905). Mining occurred on Gold Run in 1904 (Brooks, 1905). Foster and Clark (1970) reported Gold Run produced a considerable amount of placer gold.
