The <br />portion of the road on the north side does direct some concentrated flow onto the piles. <br />Reclamation Measures <br />This site contains historic structures. The structures and the waste rock pile are heavily visited and <br />photographed because of the close proximity of the County road. Because of the historic nature of <br />this site, removal and capping and revegetation are not feasible options. <br />The preferred reclamation measure for this site is a combination of diversions and in-situ <br />cementation. Diversion of the runoff from the adjacent road should be done. The road should be <br />sloped to the north to prevent flow onto the waste rock pile. The waste rock at this site could be <br />cemented with sodium silicate or a water jet injection could be tested on this site. If a waterjet is <br />used, the top of the pile will have to be neutralized with surface application of lime or limestone. <br />This will change the color of the pile, but should not disturb the historic integrity of the site. <br />Castleton Mine (Site #4) <br />is Historic Structures <br />25 <br /> <br />Location <br />This site is located near the headwaters of the mainstem of Virginia Canyon (Figures 3 and 7). This <br />waste pile was sampled as site #4. Site #4 is located across the County road from site 1 and 2, to <br />the north. Site #4 is located at LAT. N390 46' 19.2", LONG. W1050 32'23.9". The estimated volume <br />of waste rock is 7,100 cubic yards
