Wally Erickson <br />June 28, 2010 <br />Page 19 <br />Response to Adequacy Issue No. 28-11: No discharges (springs or seeps) have <br />been identified at May Day No., No.2 or May Day No. 3 (Lamb). <br />28-12. Section 6.3.3(1)(k). Regarding the statement "Sampling and analysis will cease <br />when eight samples document results suggest groundwater or surface water quality <br />will not be adversely impacted by the mining and milling process. " The possibility <br />exists that rock extracted during progressively later phases of mining will be <br />geochemically different than rock mined earlier. Therefore, the Operator should <br />continue the sampling program during all phases of mining to monitor for ground <br />water and surface water impacts. <br />Response to Adequacy Issue No. 28-12: Wildcat Mining Corporation will sample <br />every 5,000 ton of ore processed. <br />28-13. Section 633(1)(l). Regarding the statement "Sample testing will be conducted to <br />confirm preliminary findings that adverse impacts to water quality will not occur. " <br />Please elaborate on the types and frequency of testing. <br />Response to Adequacy Issue No. 28-13: Wildcat Mining Corporation will <br />complete quarterly monitoring during the period of mining, for the analyte suite in 8) <br />above. <br />28-14. Section 6.3.3(1)(m). Please provide locations ofground water monitoring. The <br />applicant must monitor for a yet-to-be determined period of time after mining <br />ceases to ensure that there are no adverse ground water or surface water impacts. <br />Response to Adequacy Issue No. 28-14: Groundwater sampling will be conducted <br />for a permitted well (Well Permit 64335, Appendix D) located on the Idaho permit area. <br />28-15. Page 36 of the Christensen report states that dewatering may be required in the <br />future to extract deeper ore. Will the phases of mining proposed in the current plan <br />extend below the water level, or will mining below the water level be proposed in a <br />future amendment? If in the current phase, please provide a plan for handling <br />dewatering effluent. <br />Response to Adequacy Issue No. 28-15: At this time, dewatering is not part of the <br />mine plan. In the event that dewatering is required, Wildcat Mining Corporation will <br />comply with all regulations, including DRMS and CDPHE discharge requirements. <br />28-16. Exhibit D, Reclamation Plan: Please provide details of the tailings encapsulation, <br />both physically and chemically. For any mine waste deposited underground, DRMS <br />will require accelerated weathering tests of the final produce to assess the leaching <br />behavior of the material. The results of the testing must be made available for <br />DRMS review before any tailings product deposition proceeds in the underground.
