Location and accuracy | This prospect is near the summit of Oakley Peak, south of Kulik Lake, in sec. 20, T. 14 S., R. 34 W., of the Seward Meridian. The location is accurate. |
Geologic descriptionThis deposit consists of pyrite-bearing quartz veins that cut Lower Jurassic, Talkeetna Formation that consists mainly of volcanic and volcaniclastic rocks (Riehle and others, 1993). The country rocks are propylitically altered. Several small prospect pits probably date from about 1966 (also see Kulik Kopper MK007). Church, Riehle, and Goldfarb (1993) report values in rocks of up to 1,000 ppm copper, 340 ppm zinc, and 2 ppm silver. | |
