|Location and accuracy||The map site of this prospect is at an elevation of about 3,500 feet, in the valley of (informally named) Rock Creek, about 2.4 miles from its junction with Wood River. The site is in sec. 5, T. 11 S., R. 1 W., of the Fairbanks Meridian. The location is accurate to within 1 mile. This is location 2 of Clark and Cobb (1972).|
Geologic descriptionLimited information suggests that this deposit consists of one or more quartz-antimony veins near the contact between the Keevy Peak Formation to the north and Birch Creek Schist to the south (Wilson and others, 1998). The veins may be related to Upper Cretaceous and Lower Tertiary intrusive rocks that cut the metasedimentary rocks nearby.
