Location: Cobb (1972, MF-413), loc. 72; SE1/4 sec. 26, T. 8 N., R. 5 W., of the Fairbanks Meridian. The Olive Creek placer mine tailings are marked along Olive Creek in the extreme northeast corner of Livengood (B-4) quadrangle. Coordinates given are for buildings adjacent to tailings.
Geology: Placer gold on the Discovery claim is in the lower 7 feet of 10 feet of angular slide gravel, and a little coarse gold is found on bedrock (Mertie, 1918). Bedrock is slate and sandstone intruded by now highly altered granitic rock. Concentrates contain gold, magnetite, ilmenite, picotite, scheelite, chromite, pyrite, arsenopyrite, zircon, limonite and plentiful cinnabar (Mertie, 1918; Overbeck, 1920).
Workings: Mining was reported in 1915, 1916, 1918, 1922, 1926, 1928-34, and 1936-40 (Cobb, 1976; OFR 76-633). Gold production was also reported in the 1980's by a small-scale sluicing opertation (Green and others, 1989).
Production: Mining was reported in 1915, 1916, 1918, 1922, 1926, 1928-34, 1936-40, and as recently as 1988, but no record of amount of production (Cobb, 1976; OFR 76-633; Green and others, 1989).
