Reclamation Feasibility Report - Virginia Canyon <br />• <br />• <br />Figure <br />Above. <br />Historic Structures <br />Scattered metal and wooden debris is all that remains at site #55. The remains of a burnt building <br />remain at site #55A <br />Water Quality Impacts <br />During normal precipitation events, this waste pile is a minor source of metals to Virginia Canyon. <br />The vegetated slopes above the mine contribute very little runoff. The access road to the Seaton <br />mine does concentrate runoff, which erodes the area between piles #55 and #55A. However, during <br />heavy precipitation events, water builds up on the bench of Pile #55, resulting in leaching of metals <br />from the pile. In addition, pile #55A slumped onto Virginia Canyon road in 1995. <br />The waste rock at this site had higher than average leachable metals. The waste rock had the <br />highest Arsenic level and high cadmium and zinc levels in the total metals analysis.
