Report: From Pioneer Technical Services (1995), there are no mill tailings present at the site. Approximately 10,015 cubic yards of waste rock is present. The waste rock contains arsenic, cadmium, copper, iron, mercury, manganese, nickel, lead, antimony, and zinc. There was a discharging adit that had a pH of 2.38. The MCLs for cadmium, nickel, and antimony were exceeded. Rock Creek flowed adjacent to the site, and the MCL for nickel in Rock Creek was exceeded (related to the site). Hazardous structures included an open adit, numerous structures, and the highwalls. The site is located one mile northeast of Neihart (Robertson, 1951). The site was prospected by shallow surface workings and two short adits. Total development work includes four adits ranging in length from 100 feet to 1,200 feet.
