Location and accuracy There are some inconsistencies in the location given in Kurtak and others (1995) but this occurrence probably is about 0.8 mile northeast of hill 809 (in meters) in the headwaters of Tukuto Creek. This location is accurate to within a half mile and the occurrence is probably in the northwest quarter of section 12, T. 34 N., R. 7 E.

Geologic setting

Geologic description

Kurtak and others (1995) briefly examined this site and collected a sample of iron-stained lithic tuff that contained 1,838 parts per million (ppm) zinc and 1,686 ppm lead. No ore minerals were visible in the sample but the values are distinctly anomalous and suggest a continuation of the mineralization they discovered several miles to the west (HW032 and HW033). Most of the rocks in the area are Lower Mississippian Kayak Shale.
