Location: This small placer mine is on Seattle Creek, a small southwest-flowing tributary to Snake River. A small amount of placer mining has taken place upstream of the Snake River road crossing of Seattle Creek. The map location is near the center of section 24, T. 9 S., R. 33 W., Kateel River Meridian. This is locality 91 of Cobb (1972 [MF 463], 1978 [OFR 78-93]).
Geology: Seattle Creek was examined during WW II and found to contain possibly important amounts of placer scheelite (Coats, 1944). Bedrock in the area includes graphitic mica schist, marble, and calc-muscovite schist, units that are probably of early Paleozoic protolith age (Hummel, 1962 [MF 247]; Sainsbury, Hummel, and Hudson, 1972 [OFR 72-326]; Till and Dumoulin, 1994; Bundtzen and others, 1994). The placer ground in Seattle Creek is underlain only by granitic orthogneiss of uncertain age. This rock underlies about 800 feet of upper Seattle Creek and is cut off on the south by a steep, northwest-striking fault (C.C. Hawley, written communication for Kennecott Exploration Company, 1995). The parts of the creek underlain by orthogneiss contain quartz boulders. About 300 feet of the creek upstream of the fault--on orthogneiss bedrock--was worked by hand methods.
Workings: About 300 feet of upper Seattle Creek was worked by shovel-in methods.
Age: Quaternary.
