|Location and accuracy||The map site of this occurrence is at an elevation of about 1,200 feet on the northeast side of the ridge between Lawrence Creek and Grass Valley. It is in the NE1/4 of sec. 4, T. 52 S., R. 73 W. Seward Meridian. It is referred to as PMRGX-22 by Wilson and others (1988, locality 70). The location is accurate to within 1200 feet.|
Geologic descriptionThis occurrence represents a group of four samples collected on the periphery of an altered silcic (silicified?) pluton intruding the Paleocene to Eocene Tolstoi Formation (Wilson and others, 1988; 1995). The northernmost of the four samples was from a basalt(?) plug or sill. The samples were collected by the U.S. Geological Survey in the mid-1980s and were reported to be anomalous in copper and zinc (Wilson and others, 1988).
