Unnamed mine (ARDF - TA024; west of upper Taylor Creek), Aniak District, Dillingham Borough, Alaska, USA

Latitude & Longitude (WGS84): 60° 52' 18'' North , 157° 26' 16'' West
Latitude & Longitude (decimal): 60.8719444444, -157.437777778


Location: This mine is in the headwaters of an unnamed north tributary to Kiknik Creek. A small saddle separates the mine from the headwaters of upper Taylor Creek (TA008) to the east. The mine, which was active as of August 2005, is in the NW1/4, section 16, T. 9 N., R. 46 W. of the Seward Meridian.
Geology: Like Taylor Creek (TA008) to the east, this placer is in a drainage that marks the approximate boundary between hornfels associated with the Taylor Mountain pluton and non-metamorphosed clastic sedimentary rocks of the Kuskokwim Group. Bedrock in the mine area is non-metamorphosed Kuskokwim Group sedimentary rocks. In some recent years to at least 2005, open cut mining has taken place on this creek early in the summer when water is available. The BLM sampled this deposit in 2004 (Ellefson and others, 2005). Their 2-pan, concentrate sample contained 40 to 60 very fine to fine gold colors. After removal of visible gold, this sample contained 305 parts per million (ppm) gold, 60.1 ppm silver, 267 ppm mercury, 1,660 ppm manganese, 2,350 ppm tin, less than 0.01 ppm tantalum, and 820 ppm tungsten. Two samples of sluice concentrate contained 556 and greater than 1,500 ppm silver, 37.1 and 171 ppm mercury, 5,130 and greater than 10,000 ppm manganese, 1,400 and 2,330 ppm tin, 0.6 ppm tantalum, and 15.7 and 36 percent tungsten. Abundant wolframite with minor magnetite and scheelite were identified in the concentrate samples.
Workings: In some recent years to at least 2005, open cut mining has taken place on this creek early in the summer when water is available. The BLM sampled this placer in 2004.
Age: Quaternary.
Production: In recent years and through 2005, this mine produced a small amount of gold each year. The concentrates also contain some tin and tungsten but neither commodity is recovered or marketed.
Reserves: Unknown but probably some (in 2005).

Commodities (Major) - Au; (Minor) - Ag, Sn, W
Development Status: Yes, small
Deposit Model: Placer Au (Cox and Singer, 1986; model 39a)
