Reclamation Feasibility Report - Virginia Canyon <br /> <br />Reclamation Measures <br />The recommended reclamation measure for this site is to remove the waste rock near the stream <br />and consolidate on-site. The waste rock within 10 feet of the stream channel should be moved to <br />the main pile toward the county road. The toe of the reclaimed pile should be armored with riprap to <br />prevent future erosion if the stream meanders. Diversion ditches should also be constructed to <br />convey run-on water around the pile. <br />Diamond Joe Mine (Site #12) <br />Location <br />The Diamond Joe Mine is located in the mainstem of Virginia Canyon approximately 2.4 miles above <br />Clear Creek (Figures 3 and 23). The mine waste pile was sampled as site #12. Site #12 is located <br />at LAT. N390 45'56.8", LONG. W1050 32'09.4. The estimated volume of mine waste is 8,000 cubic <br />yards. <br />Historic Structures <br />There has been some recent activity at this site. A portion of the waste rock pile has been pushed <br />out of the stream. There is some scattered debris at the site, including rail. The adit has recently <br />been re-collared. <br />Water Quality Impacts <br />The stream bifurcates this waste pile. A portion of the waste rock is mixed with stream-eroded <br />material. Even with some alluvial material in the sample, this waste rock had one of the five highest <br />concentrations of soluble copper. The waste rock has partially dammed the stream. There is likely <br />to be some leaching of the waste rock by ground water, due to the damming. Results from the 2:1 <br />leachate analysis are given below: <br />48 <br /> <br />Figure 23.
