|Location and accuracy||The map site of this occurrence is at an elevation of 1,800 feet, about 2.0 miles east of Beaver River and 3.1 miles north of Beaver Bay. It is referred to as PMRGX-25 by Wilson and others (1988, locality 73). The location is accurate to within 2,500 feet.|
Geologic descriptionAt this site a dark shale member of the Upper Cretaceous Hoodoo Formation is cut by quartz veinlets and by an andesite sill containing disseminated pyrite (Wilson and others, 1988; 1995). The occurrence is on the periphery of a diorite(?) plug or sill that crops out to the east. Four samples collected by the U.S. Geological Survey in the mid-1980s were reported to be anomalous in arsenic, barium, copper, and zinc (Wilson and others, 1988).
