Location: Gold Run Creek is a northeast-flowing stream with headwaters against the northeast side of the Kiwalik Mountain upland. This location is approximately located on upper Gold Run Creek, probably within one mile. It is locality 61 of Cobb (1972; MF 417; 1975; OFR 75-429).
Geology: Placer gold was discovered on Gold Run Creek in 1908 and mining or exploration activities were reported for many years up to WW II (Cobb, 1975, OFR 75-429). Early mining was in ground 6 to 12 feet deep in the upper creek (Henshaw, 1910). Scheelite, wolframite, and kyanite were reported to be present in placer concentrates and kyanite was exposed in a placer cut (Anderson, 1947). Bedrock along the north and east side of Kiwalik Mountain is part of Lower Paleozoic metasedimentary assemblage that includes metamophosed felsic dikes or sills thought to be related to the Devonian Kiwalik Mountain gneiss (Till and others, 1986). The metasedimentary assemblage includes marble, metapelitic rocks, and in some areas quartz-mica rocks that may be metatuffs or exhalites. Felsic metavolcanic rocks are present in this assemblage at the HOM (BN077) and Big Bar (BN083) prospects. Some skarn-like rocks are also present locally on this side of Kiwalik Mountain. The Lower Paleozoic assemblage is inferred to lay unconformably on polydeformed metapelitic schist of Monument Mountain that may be Precambrian in age.
Workings: Surface open-cut placer workings are present locally on this creek.
