Geochemistry and Water Quality Review Adequacy Response <br />Wildcat May Day; DRMS File No. M-1981-185 Conversion Application CN-1 <br />waters have the potential to be contaminated by designated chemicals used in the <br />extractive metallurgical process or by materials that are toxic or acid-forming, or that <br />produce acid mine drainage." This information will be of great use to the Applicant in <br />compliance with Hard Rock Rule 6.4.21(8). <br />Response #5 <br />Wildcat Mining proposes to transport a drill rig to the site to drill two wells for the purpose <br />of ground water quality sampling, monitoring, and as a point of compliance. The two wells <br />are intended to provide data to supplement the body of data accumulated by Wildcat <br />Mining over the last five calendar quarters from five different testing locations, including: <br />on the Little Deadwood Creek upstream and downstream of the Site; on the La Plata River <br />upstream and downstream of the Site; at the Idaho spring; and, during the fifth quarter, at <br />the downstream wetlands. Provisionally, the location of the two wells will be at the Idaho <br />Spring and May Day No. 2 portal. Wildcat Mining proposes that the wells will be drilled to <br />a depth at or slightly below the depth of the La Plata River and that ground water <br />sampling would commence immediately. Wildcat Mining's current water quality testing <br />results indicate that the character of the ground and surface water is identical. Wildcat <br />Mining believes that due to fracture flows through the mine the ground water is simply the <br />surface water dropping into the mine fracture system. Neither source and none of the <br />Wildcat Mining's test results to date evidences any actionable contamination from the site. <br />Wildcat Mining proposes that ground water sampling would occur for at least two quarters <br />and, pending the results of the water quality test results, full mining activity would be <br />allowed following the second quarter with the understanding that the wells would remain <br />in operation for monitoring purposes, until further agreement of the parties. <br />Adequacy Issue #6 <br />Please see comment 5 above. Otherwise adequate. <br />Response #6 <br />Noted. <br />Adequacy Issue #7 <br />The Applicant has not adequately demonstrated that all of the rocks in the mine are non- <br />hazardous or non-toxic-producing. Therefore, the Applicant shall conform to the geochemical <br />testing protocols as described elsewhere in the Division's adequacy reviews. <br />6/6/11
