Location: Cobb (1972, MF-413) loc. 70. These placer deposits are scattered in the lower mile of Lucky Creek, a tributary of Livengood Creek. The coordinates given are for the placer deposits closest to the mouth of Lucky Creek. Accuracy is within 2,000 feet. Lucky Creek is also called 'Goodluck Creek' and 'Lucky Gulch'. The creek is named 'Lucky Creek' on the U.S.G.S. Livengood C-3 quadrangle.
Geology: Placer mining was reported in 1918, 1934, and 1939. At the lower placer, some flakey gold was obtained just above bedrock. About 1,500 feet upstream, some fine gold is present in angular wash almost at the surface (Mertie, 1918). Minerals in samples from old placer dumps included limonite, hematite, magnetite, epidote, spinel, chromite, ilmenite, gold, cinnabar and cassiterite (Wedow and others, 1954). The bedrock in the basin is chiefly chert and silicified Mississippian limestone. There is a small body of diorite on greenstone near the head of Lucky Creek which may be a dike between the chert and limestone (Wedow and others, 1954). One sample contained a mineral in the euxenite-polycrase series, rare-earth, uranium, niobates and titanates (Wedow and others, 1954). Chromite and chrome spinels are abundant in Lucky Gulch and are probably derived from serpentine in Middle Devonian basic volcanics (Joesting, 1942; ATDM Pamph. 1, p. 17).
Workings: During placer mining, one shaft was sunk 60 feet to bedrock (Mertie, 1918, p. 268).
Production: Placer mining was reported in 1918, 1934, and 1939, but there is no record of amount of production.
