|Location and accuracy||The occurrence is located on the north side of Harriman Glacier at an elevation of about 1,500 feet. It is in the N1/2 section 12, T. 10 N., R. 5 E., of the Seward Meridian. This is location S-142 of Jansons and others (1984). This location is accurate to within half a mile.|
Geologic descriptionThe occurrence is hosted in carbonaceous, pyritiferous slate and hematite-stained conglomerate (Hoekzema and Sherman, 1983) of the Valdez Group of Late Cretaceous age (Nelson and others, 1985). The deposit is in a shear zone and consists of pyrite- and galena-bearing quartz veins and stockwork veinlets. The largest vein examined strikes N55W and dips steeply southwest. The conglomerate locally contains clasts as much as 12 inches in diameter that are extremely fractured and healed with quartz veins. A single grab sample contained 0.03 ppm gold (Hoekzema and Sherman, 1983).
