Location: The occurrence is at an elevation of about 5,500 feet near the head of a north-flowing tributary glacier to Chistochina Glacier. The occurrence is in the SW1/4SW1/4 section 18, T. 20 S., R. 16 E., Fairbanks Meridian. The site corresponds to locality 22 of Rose (1967), locality 23 on figure 6 of Cobb (1979 [OFR 79-238]), and locality 141 in table 2 of Nokleberg and others (1991).
Geology: The rocks in the vicinity of the occurrence are argillite, probably of the Eagle Creek Formation of Early Permian age (Richter and Dutro, 1975), a unit formerly assigned to the Mankomen Formation. The rock has been pyritized. An assay showed a trace of gold and 0.12 ounce of silver per ton (Rose, 1967).
Workings: The mineral site is a natural outcrop; only limited surface sampling has been done.
Age: Early Permian or younger.
Alteration: Pyritization.
