Response to Geochemistry Review - May Day Conversion CN-1 <br />File No. M-1981-185 <br />The point of compliance for groundwater will be at the mine pool, at the groundwater <br />production well or at the base of the proposed dry stack tailings disposal site. DRMS has <br />not accepted the Idaho Spring water quality as being representative of groundwater. <br />Therefore, alternative points as described in the previous sentence are being offered as the <br />groundwater point of compliance Wildcat Mining has adopted the water quality <br />standards referenced by DRMS. <br />Groundwater monitoring, wells may be completed if groundwater is encountered during <br />future exploration activities. Wildcat Mining has adopted the water quality standards <br />referenced by DRMS. <br />Adequacy Issue #7 <br />Exhibit E - Reclamation Plan; Rule 3.1.5(2), item 2, page 6. The reclamation plan proposes to <br />permanently dispose mill tailings and debris from the dismantled mill facility in the underground <br />workings. The application does not demonstrate such plan will be compliant with the ground <br />water quality regulations. The Division cannot approve the proposed reclamation plan until the <br />Applicant demonstrates such plan will be compliant with the ground water regulations and <br />protective of existing and reasonably potential future uses of ground water, per Rule 3.1.7. <br />Response #7 <br />Wildcat Mining will dispose of mill material in an environment that will eliminate water <br />quality impacts and concerns per rule 3.1.7. Wildcat Mining has demonstrated the mine <br />rock is not hazardous or toxic producing and has demonstrated the chemicals to be used to <br />concentrate ore will not impact the environment. The mine has been in operation since the <br />early 1900s and surface and groundwater quality have not been affected by past mining <br />activities Based on all presented data, water quality impacts will be minimized or <br />prevented. <br />Adequacy Issue 48 <br />Exhibit E - Reclamation Plan; Rule 3.1.7(7)(a), Ground water monitoring, page 11. The locations <br />at which down gradient impacts may reasonably be expected are not well known, because the <br />ground water regime is not well characterized. The Applicant must submit a proposed <br />monitoring well and piezometer network that will allow the determination of the ground water <br />flow regime, including the depth to the water table at various locations in the mine vicinity, the <br />piezometric surface, ground water flow directions, and ground water discharge rates. <br />Response #8 <br />See Adequacy response #7 and #8. <br />May Day Idaho Mine Complex 112(d) Permit Application <br />Revised: April 14, 2011 <br />4
