Geologic descriptionRedman and others (1984) describe this occurrence as, 'Malachite-stained quartz veins that cut diorite and carry chalcopyrite and bornite.' The veins trend N25E and dip 55E. They can be traced for at least 330 feet and occupy a zone 80 feet wide. A sample of mineralized vein contained 5.73% copper and 21 ppm silver. The mineralization is near a metabasalt body that is probably a pendant within the mid-Cretaceous, Mount Kashagnak pluton. This is probably the same occurrence referred to by Buddington and Chapin (1929) who report bornite and hematite from quartz veins about 10 miles northwest of Haines. |
