Report: Mill tailings were present at the site, and the volume of the tailings was estimated to be 255 cubic yards. The tailings contained elevated levels of silver, arsenic, barium, cadmium, copper, mercury, manganese, nickel, lead, antimony, and zinc. The volume of waste rock was estimated to be 21,860 cubic yards and had elevated levels of silver, barium, copper, manganese, lead, arsenic, cadmium, mercury, nickel, and zinc. There were not any discharging adits present at the site. There were also not any filled shafts, seeps and springs observed at the site. The Hartley mine is located on the northwest side of Neihart Baldy Mountain about a half mile northeast of Neihart (Robertson, 1951). The site was a silver, lead, and zinc mine. The main drift was 1,000 feet long and a winze was sunk 500 feet deep. The main vein reached widths of up to 4 feet.
