Reclamation Feasibility Report - Virginia Canyon <br />• The highest priority for reclamation should be diversion of water away from the waste rock piles. <br />Diversions will be the most cost effective methods to reduce heavy metals contributions to Virginia <br />Canyon. Removal of some of the waste rock piles will require construction of a repository in order to <br />be cost effective. <br />Road drainage patterns should be studied to determine where culverts and drainage control berms <br />should be placed to minimize erosion of the mine waste piles. The crystal stope should be capped <br />to prevent road drainage from entering the mine workings, which could possible eliminate this <br />perennial or near perennial source of heavy metals. The shaft at site #13 should also be capped to <br />prevent water from entering the mine workings, which may contribute to mine drainage from adit <br />DM-2. <br />Erosion of material from the gravel roads has been observed to contribute greatly to the sediment <br />load during thunderstorms in Virginia Canyon. It is recommended that sediment traps be <br />constructed and maintained near culvert crossings in the major drainages. <br /> <br />• <br />70 <br />
