Comments on the geologic information

  • Geologic Description = In 1942, a placer cut on Willow Creek exposed high-grade stibnite in several parts of a wide quartz zone (Joesting, 1943). The vertical vein of stibnite with occasional quartz and other sulfides is 6 to 8 inches wide and was traced N 40 E for 75 feet (Killeen and Mertie, 1951). Nearby in 1912, a shaft was sunk 16 feet on a narrow quartz stringer carrying stibnite (Killeen and Mertie, 1951). Massive stibnite was identified on the dumps at the Johnson and Martin prospect with coarse grained scheelite (Byers, 1957). The prospect was examined by Metz and Robinson (1980) who noted that massive stibnite and scheelite were in quartz muscovite schist striking N 60 E and dipping 25 NW. Ore exposed in a 28-inch-thick horizon in a small pit on the prospect contained abundant coarse- to fine-grained stibnite, discrete bands of coarse scheelite grains to 0.8 inches across, and minor pyrite and arsenopyrite. By volume, stibnite constitutes 95% of the lens, scheelite 4% and arsenopyrite and pyrite constitute 1% each. In 1986 the prospect was examined by Fairbanks Exploration Inc. (Fairbanks Exploration Inc., unpublished report, 1986). The deposit consisted of disseminated to massive coarse-bladed stibnite with coarse-grained scheelite crystals disseminated in the stibnite. Gold values ranged from 420 ppb to 2450 ppb, silver values ranged from trace to 2.21 ounces of silver per ton, antimony values were greater than 10,000 ppm and arsenic values ranged from 600 to 800 ppm. Extensive trenching was conducted by Yukon Tanana Mining Company in the vicinity of the Johnson and Martin prospect in 1988, however the results of this work are not known (Freeman, 1992).
