Location and accuracy This occurrence is at an elevation of about 3,500 feet northeast of Windy Creek. The map site is about 1.5 miles north of the confluence of Windy Creek and West Fork Windy Creek, in the south-central part of sec. 3, T. 17 S., R. 8 W., of the Fairbanks Meridian. The location is accurate to within 3,000 feet. This is location 3 of Hickman and Craddock (1976).

Geologic setting

Geologic description

This occurrence is in Pennsylvanian to Upper Triassic graywacke and argillite, and consists of a few small veinlets (up to 1-inch wide) of sphalerite, stibnite, and pyrite. Pyrite also is disseminated in the wallrock adjacent to the veins. The deposit has a strike length of at least 150 feet. Samples contain 8,800 ppm lead, 2,200 ppm zinc, 14.9 ppm silver, 2,000 ppm antimony, and traces of arsenic (Hickman and Craddock, 1976).
