Location: This occurrence is at an elevation of about 3,500 feet, about 0.4 mile south-southeast of VABM Allen. The occurrence is the site of sample 84 in Dillon and others (1981 [AOF 133B]). The location is accurate within one-half mile.
Geology: This occurrence consists of a quartz vein that contains abundant bornite, lesser amounts of covellite, and traces of chalcopyrite altering to malachite. The vein cuts calcareous schist. A sample of the vein contains more than 2% copper and 100 ppm silver (Dillon and others, 1981, sample 84 [AOF 133B]). Degenhart and others (1978) reported minor amounts of chalcopyrite, bornite, and malachite in metamorphosed, reef limestone a short distance north of this occurrence.
Workings: Only surface sampling.
Alteration: Chalcopyrite oxidizing to malachite.
