Location: This small alluvial placer gold mine is on Prospect Creek, a small east tributary to Snake River. This placer is upstream of the Snake River road crossing of Prospect Creek and 1.5 miles west-southwest of Mount Byrnteson. The map site is in the south-central part of section 10, T. 10 S., R. 34 W., Kateel River Meridian and includes localities 41 and 96 of Cobb (1972 [MF 463], 1978 [OFR 78-93]). The location is accurate to within 500 feet.
Geology: Small amounts of placer gold and scheelite occur in Prospect Creek gravels (Anderson, 1947; Thorne and others, 1948). One claim (the Terri) was surveyed for patent in 1976, and patent was granted in 1977 (U.S. Mineral Survey No. 2270. The Terri claim and an unpatented adjacent claim were mined for about 300 feet, probably by the claim owner, William Ullrich. Bedrock in the area is graphitic schist that 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). Anderson (1947) reported a galena- and bismuth-bearing quartz vein on Prospect Creek, but the exact location of the vein is unknown.
Workings: One pit was mined on the upper Terri claim, possibly in the 1960s or 1970s. The claim was patented in 1977.
Age: The placer deposit is Quaternary. The vein cuts schist metamorphosed during the mid-Cretaceous.
