Köppen climate type:
May be same location described by Proffett (1977) as a 'steep North-South striking, cross cutting quartz vein with coarse chalcopyrite. The ore-bearing part is 1 to 3 ft. wide and may average 5 to 10 percent copper. The vein is more than 1,000 ft. in strike length.' Proffett (1977) also estimated that the occurrence 'may have potential for 10,000 - 100,000 ton' deposit. Cathrall and other (1977) reported 1 ppm Ag in a rock sample (sample number 75 RR 121).
Location: Site is at an elevation of about 4,700 ft. approximately 1 1/4 miles east of Beaucoup Creek (SE1/4 sec. 35, T. 14 S., R. 19 E., of the Umiat Meridian). Location accurate within 1-mile radius.
Geology: Occurrence described only as visible chalcopyrite and anomalous silver occurring in a quartz vein in Skajit Limestone beneath the contact with the Beaucoup Formation (Menzie and others, 1985). The area is mapped as the conglomerate member of Beaucoup formation (Menzie and others, 1985).
