Location: This occurrence is at an elevation of about 3,950 feet in the saddle west of elevation 3972; it is near the center of the SW1/4 sec. 1, T. 32 N., R. 3 E., Seward Meridian. The location is accurate to within 1/4 mile.
Geology: This occurrence consists of disseminated pyrite in fine-grained schist, adjacent to a Tertiary granitic intrusion (Kurtak and others, 1992). A sample of the schist contains 200 parts per million copper and 100 parts per million zinc (Miller and others, 1978). Four U.S. Bureau of Mines samples contain up to 56 parts per million copper (Kurtak and others, 1992).
Workings: Surface sampling by U.S. Geological Survey and U.S. Bureau of Mines (Miller and others, 1978; Kurtak and others, 1992).
