Reclamation Feasibility Report - Virginia Canyon <br />• To neutralize the waste rock, it is recommended that the waste piles be sprinkled with a mixture of <br />lime and water. Sodium hydroxide could be used instead of lime. The piles can be sprinkled over a <br />period of several weeks to allow the high pH water to percolate into the piles. Following completion <br />of sprinkling, a slurry of ground limestone should be applied to the waste pile and the vegetation kill <br />zone, then the entire area should be seeded and fertilized. <br />Unknown Site #82 <br />Location <br />This site is located in the streambed of Virginia Canyon approximately 2.1 miles above Clear Creek <br />(Figures 3 and 36). The mine waste pile was sampled as site # 82. The waste pile is located at LAT. <br />N390 45'49.6", LONG. W1050 32'03.1 ". The estimated volume of mine waste is 600 cubic yards. <br />• <br />Historic Structures <br />There are no historic structures or artifacts at this site. <br />Water Quality Impacts <br />Virginia Canyon has heavily eroded the waste rock pile at this site. The top of the pile is covered <br />with debris and is partially vegetated. During May of 2000, a spring was observed flowing from the <br />base of the pile. The source of the water was apparently stream flow that had infiltrated into the <br />• alluvium, then surfaced at the toe of the waste pile. This indicates that there may be some leaching <br />66
