Location: Cobb (1972, MF-413), loc. 65; SE1/4NE1/4 sec. 15, T. 8 N., R. 5 W., of the Fairbanks Meridian. The Ruth Creek placer mine is near the mouth of Ruth Creek, a tributary of Livengood Creek, near the old town of Livengood.
Geology: Gold is found at the base of the gravels and in the top 2 feet of bedrock with a paystreak 30 to 40 feet wide (Mertie, 1918). Black crystalline limestone with calcite and quartz veins slopes away from the creek on both sides (Mertie, 1918). Gold was reportedly high grade, netting $18/oz after charges (Mertie, 1918). Placer mining took place from as early as 1916 to as late as 1940 (Cobb, 1976; OFR 76-633). Concentrates contain gold, scheelite, magnetite, cinnabar, chromite, pyrite, arsenopyrite, zircon, monazite, chrome spinels and stibnite (Cobb, 1976; OFR 76-633, p. 164-166).
Workings: Placer mining took place from as early as 1916 to as late as 1940 (Cobb, 1976; OFR 76-633).
Production: Foster (1968) reported that Ruth Creek had been a major placer-gold producer, but there is no data on the amount produced.
