|Location and accuracy||The occurrence consists of several mineralized zones near the head of Placer Creek where it drains Lowell Glacier and at an elevation of 1,500 feet. This occurrence is in the E1/2 section 23, T. 2 N., R. 3W., of the Seward Meridian. This is location S-207 of Jansons and others (1984). This location is accurate to within a quarter of a mile.|
The Placer Creek occurrence consists of quartz veins containing massive sulfide pods interbedded with siltstone and calcareous sandstones (Hoekzema and Sherman, 1983). Sulfide minerals include galena, sphalerite, and chalcopyrite. Nelson and others (1985) mapped the bedrock in this area as sedimentary rock of the Valdez Group of Late Cretaceous age.A single grab sample assayed 0.56 ounce of gold per ton, 11.34 ounces of silver per ton, 1.25 percent copper, 1.75 percent zinc, and 2.6 percent lead (Jansons and others, 1984). No further information is published.
