Response to Preliminary County Comments Received on March 17, 2011 <br />Secondary Preliminary Adequacy Issue #5 <br />Exhibit E - Reclamation Plan; Rule 3.1.7(2)(c)(ii), page 7. Please describe how ambient <br />groundwater quality will be determined. <br />Response #5 <br />Ambient groundwater quality data will be collected from the point of compliance which is <br />the proposed groundwater production well (May Day No 1 bench) or the base of the drv <br />stack tailings pile. In addition, Wildcat Mining Corporation proposes to drill a monitoring <br />well north of the Idaho No. 1 spring and a second monitoring well on May Day No 2 <br />bench. The wells are located to provide to determine the depth to groundwater and to <br />obtain a sample to benchmark groundwater quality characteristics The wells will be <br />drilled 10 feet below the elevation of the La Plata River. If water is not encountered the <br />hole will be abandoned and Wildcat Mining will seek a determination that no groundwater <br />of significance exists at the location. If water is encountered at the elevation of the La Plata <br />River, a 4 to 6 inch well will be completed and tested for production yields and water <br />quality. If the groundwater quality has water quality characteristics are similar to surface <br />and spring water quality samples previously collected by Wildcat Mining, Wildcat Mining <br />will seek a determination that groundwater and surface water quality are adequately <br />characterized. If surface and groundwater well water quality are similar, Wildcat Mining <br />will seek determination that background water quality is considered to be adequately <br />characterize to address DRMS groundwater monitoring regulatory requirements If <br />groundwater quality is significantly different from surface water, Wildcat Mining will <br />continue groundwater monitoring to characterize groundwater quality. If groundwater <br />needs to be further characterized, Wildcat Mining will conduct mining activities above the <br />water table and will focus on storing dry stacked tailings in the underground workings. <br />Secondary Preliminaa Adequacy Issue #6 <br />A. Exhibit E - Reclamation Plan; Rule 3.1.7(6), page 10. The Applicant must specifically <br />state where the points of compliance (POC) will be for surface water. Sampling station <br />SW-2 appears to be satisfactory as the surface water POC, but this must be explicitly <br />stated in the application. <br />B. For ground water, the Division does not believe that the Idaho seep is satisfactory as a <br />ground water point of compliance due to the probability that all ground water in the May <br />Day area may not report to the Idaho Seep. The receptor of greatest concern to which <br />ground water from the site may report is the La Plata River, which is a local drinking <br />water source. <br />Therefore, the relevant ground water containment limits shall be the domestic water <br />supply and drinking water standards, except as noted in Colorado Water Quality Control <br />Commission (WQCC) Region 9 stream classifications. <br />Revised <br />4/14/2011 <br />27
