|Location and accuracy||This prospect is at an elevation of about 2,700 feet on the northeast bank of Kansas Creek, approximately 2 miles upstream from its junction with Wood River. It is in sec. 17, T. 12 S., R. 1 W., of the Fairbanks Meridian. The location is accurate to within 1.5 miles. This is location 3 of Clark and Cobb (1972).|
Geologic descriptionThe prospect is in the Lower Paleozoic or possibly Upper Precambrian Birch Creek Schist, comprising quartz-sericite schist, quartzite, and a few interbeds of massive marble (Wilson and others, 1998). Locally, Lower Tertiary and Upper Cretaceous granites intrude the metasedimentary rocks. The deposit consists of quartz veins containing stibnite and minor galena and sphalerite. No gold and silver has been reported (Cobb, 1978; OFR 78-1062).
