| Location and accuracy | This occurrence is at the top of hill 3836, in section 6, T. 28 N., R. 22 W., of the Fairbanks Meridian. The site corresponds to the location of sample no. 80 in Dillon and others (1981 [AOF 133B]). The location is accurate. |
Geologic descriptionThis occurrence consists of a mineralized stockworks of quartz veins in dolomite (Dillon and others, 1981 [AOF 133B]). The rocks in the area are Devonian, Skajit Limestone, with subordinate metabasite (Dillon and others, 1986). The veins contain malachite, azurite, bornite(?), and galena. A sample of quartz near a contact with greenschist with 5% magnetite, contains up to 1,500 ppm copper, 1,000 ppm antimony, 240 ppm zinc, and no detectable lead. | |
