| Location and accuracy | The occurrence is located on the beach about 3/4 mile north of Cape Resurrection in section 33, T. 3 S., R. 1 E., of the Seward Meridian. This is location 110 of Tysdal (1978) and is accurate to within one quarter of a mile. |
Geologic descriptionThe host rock is Upper Cretaceous sheeted basalt of the Valdez Group that has been sheared and brecciated (Tysdal, 1978). he shear and breccia zone is 0.6 meters wide and contains quartz, pyrite, chalcopyrite, and galena. Analysis showed 3 ppm silver, 70 ppm cadmium, 1,500 ppm copper, 3,000 ppm lead, and 9,200 ppm zinc. Tysdal (1978) considers this occurrence to be a volcanogenic massive sulfide deposit. | |
