The occurrence is in the Wrangell-St. Elias National Preserve.
Location: This occurrence is on the east side of the glacier at the head of the middle fork of Bond Creek. It is at an elevation of about 7,000 feet, 1,300 feet southwest of peak 8075, and 1,000 feet east of the glacier. The occurrence is about 0.4 mile west of the center of section 34, T. 5 N., R. 15 E. of the Copper River Meridian. It is locality 15 of Richter (1973), locality 32 of Richter and others (1975), and National Park Service locality WRST-40 (unpublished data). This locality is included as an 'Unnamed occurrence' by Cobb and Richter (1980). It is located to within a few hundred feet.
Geology: At this occurrence, brecciated and highly altered volcanic rocks of the upper Paleozoic Tetelna Volcanics are cemented by quartz that contains minor pyrite and chalcopyrite (Richter, 1973; Richter and others, 1975; Richter, 1976). A sample of altered volcanic rock contained 1,500 parts per million copper (Richter and Matson, 1970 [OFR 70-276]). The volcanic rocks are intruded by small Tertiary porphyry dikes and stocks.
Age: Tertiary? The mineralization may be related to the small Tertiary intrusives in the area.
Alteration: The host rocks to this deposit are highly altered but the type and extent of alteration have not been reported. The area is iron-stained.
Commodities (Major) - Cu
