Location: The map site of this occurrence is at an elevation of 850 feet, on the northeast side of a prominent ridge that extends northwest from the head of Clark Bay. The site is about 0.1 mile northeast of the center of sec. 2, T. 51 S., R. 70 W., of the Seward Meridian. It is referred to as PMRGX-31 by Wilson and others (1988, locality 79). The location is accurate to within 2,500 feet.
Geology: At this site conglomerate, sandstone, and siltstone of the Paleocene to Eocene Tolstoi Formation are cut by quartz veins and by altered aphanitic dikes or sills (Wilson and others, 1988; 1995). Six samples collected by the U.S. Geological Survey in the mid-1980's were reported to be anomalous in antimony, arsenic, copper, lead, silver, and zinc (Wilson and others, 1988). One mile to the west, a sample of hornfelsed siltstone contained anomalous values in silver.
Workings: Rock samples 83AYb532-537 and 83AWs105b (Wilson and others, 1988) were reported to be anomalous in antimony, arsenic, copper, lead, silver, and zinc.
