Location: The map site of this occurrence is at an elevation of about 1,250 feet, on a ridge approximately 3.5 miles east of the head of Albatross Anchorage. The site is 0.15 mile southeast of the center of sec. 8, T. 53 S., R. 73 W., Seward Meridian (Christie, 1974, part of color anomaly 76; Wilson and others, 1988, locality 69). The site is referred to as PMRGX-20 by Wilson and others (1988). The location is accurate to within 1,200 feet.
Geology: At this site altered andesitic dikes intrude altered Miocene volcanic and sedimentary rocks (Wilson and others, 1995). Three samples collected by the U.S. Geological Survey in the mid-1980's were reported to be anomalous in copper, lead, and zinc (Wilson and others, 1988).
Workings: Rock samples 85AYb739-740 and 85AJm805 collected by the U.S. Geological Survey in the mid-1980s were reported to be anomalous in copper, lead, and zinc (Wilson and others, 1988).
