Reclamation Feasibility Report - Virginia Canyon <br />surface. The waste rock is not particularly high in soluble heavy metals compared to other piles in <br />a Virginia Canyon, but erosion of the waste into Boomerang Gulch subjects the eroded material to <br />frequent leaching. Results from the 2:1 leachate analysis are given below: <br />^:l- JA AG <br /> <br />pH <br />S.U. aiav n?v <br />Total Acidity <br />m /I <br />As <br />b <br />Cd <br />b <br />Cu <br />b <br />Fe <br />b <br />Mn <br />b <br />Pb <br />b <br />Zn <br />b <br />3.43 108 BDL 76 590 50 400 5800 13000 <br />Reclamation Measures <br />Because of the high visibility of this waste pile, removal is not recommended. This waste pile and <br />others like it contribute to the historic mining flavor of Virginia Canyon. <br />The preferred alternative is to direct the road drainage away from the waste rock. A portion of the <br />road drainage should be culverted into the small ephemeral drainage around the corner to the east. <br />The remaining drainage should be taken directly to the Boomerang Gulch channel crossing. The <br />road drainage should not be culverted at the small drainage to the northwest because the road <br />outslope contains mine waste from sites 43, 140 and 141. <br />Casino Mine( ite #53) <br />Location <br />This site is located near the headwaters of Seaton Gulch approximately 200 yards below the Gilson <br />Gulch turnoff (Figures 3 and 17). The waste pile is located in the drainage immediately below-the <br />county road. This waste pile was sampled as site #53. Site #53 is located at LAT. N390 45'29.1", <br />LONG. W105030'51.1". The estimated volume of waste rock is 5,500 cubic yards <br />• <br />• <br />38
