Abstract
Assesses mine site on moderately steep side slopes consisting of four collapsed adits and about 1500cy of wasterock. A Niton XLt unit found most metals detected at the site exceeded screening criteria for birds, invertebrates, and plants, but only arsenic (84.1 mg/kg) exceeded EPA Regional goals. Based upon the location of the adits, lack of evidence of water discharge from the mines, lack of surface water sources, and relative ease of access by the general public, the site has been ranked a Low Priority for further assessment.
