Stabilization Tank to the head of the PSES where it will recombine with the other AGADR barren <br /> solutions. From this point on, barren solution distribution remains unchanged from current flows. By <br /> leaching Phase II pregnant solution separately, ADR1 recoveries will improve. The lime addition at the <br /> Stabilization tank will prevent solids from plugging the barren distribution system after the PSES. Figure <br /> 2 details this proposed modification flow, and Figure 3 details the location of this modification. <br /> Modification#2: <br /> Pregnant leach solution from Phase Il will be routed via a new pipe to the existing Stabilization Tank to <br /> mix with slaked lime in order to increase recovery. The lime will be routed via pipe from a new, 20,000 <br /> gallon storage tank. The ore/lime mixture will be removed from the bottom of the tank and hauled by <br /> truck to both of the VLFs (AG and Squaw Gulch) for further recovery. This solid mixture, in turn, will <br /> further increase the pH of the VLFs, which will also aid in recovery. Prior to removal, the Phase II <br /> solution valve will be shut off. Once removal is complete, the Phase II solution and lime will be <br /> reintroduced to the Stabilization Tank by turning the lines on again. The solid mixture is anticipated to be <br /> removed annually; although the actual frequency may vary upon implementation. Figure 4 details this <br /> proposed modification. Figure 5 details the location of these changes in relation to the ADR Facility. <br /> Modification#3: <br /> Pregnant solution from Phase II will be gravity-fed via pipe from Train A and B to the PSES. Slaked lime <br /> will be introduced at the discharge side of Train A and B prior to entering the CoMag Clarifier at the <br /> PSES. The overflow from the clarifier will then be gravity-fed into the stabilization tank while the <br /> underflow, a heavy solid will be pumped into solid thickener and then filter pressed. The filter press <br /> product will be taken to the VLF. Figure 6 details these recommended modifications. Figure 7 details the <br /> locations of these changes. Additional piping changes will be located inside the PSES. <br /> Implementation Schedule: <br /> Pending DRMS approval and recommendations of one of these modification options, CC&V will begin <br /> construction immediately. <br /> Financial Warranty: <br /> CC&V has determined the guidelines presented within this TR will not affect the financial warranty. <br /> Enclosed please find check no. 200037429 in the amount of $1,006.00 for the technical revision fee. <br /> Should you require further information please do not hesitate to contact Katie Blake at 719.689.4056 or <br /> Katie.Dehlin(a�newmont.com or myself at 719.689.4055 or Meg Burt(a newmontxom. <br /> Sincerely, <br /> P <br /> Meg Burt <br /> Senior Envir nmental Manager <br /> Cripple Creek and Victor Gold Mine <br /> MB/kb <br /> Ec: Tim Cazier,DRMS <br /> Figures: 7 <br /> 2 <br />
