• added to the circuit and will provide power for the ADR as part of the MLE Project in the <br />event of power failure to line power supply system. <br />The potential total amount of solution in circulation will be about 29,100 gpm, distributed <br />equally between the Phases I, II, III and IV VLF and associated PSSAs and the Phase 5 <br />VLF and PSSA. At any one time, the amount entering the ADR for gold recovery will be <br />no more than approximately 14,500 gpm. Water balances associated with the Phases I, II, <br />III and IV VLF and associated PSSAs have been previously approved under Amendment <br />No. 8 for up to 19,000 gpm of solution application. This MLE presents information in <br />Section 6.0 to support an average solution application at a rate of approximately 14,500 <br />gpm at Phases I, II, III and IV VLF and an average solution application at a rate of <br />approximately 14,500 gpm at Phase 5 VLF. The water balance model for the MLE <br />Project specifies total maximum flows within the all phases of the VLF at about 29,100 <br />gpm. <br />Cyanide addition to the enrichment solution circuit will be into the discharge header of <br />the four 800 horsepower pumps prior to delivering the solution to Phase 5. The <br />concentration of cyanide in the enrichment solution will be approximately 120 to 150 <br />is ppm. Cyanide addition will utilize the existing infrastructure in the ADR with minor <br />piping required to reach the enrichment discharge header. <br />Lime addition to the ore at the crushing circuit will provide pH control for the enrichment <br />solution. It is anticipated that between about 10 and 11 pounds of lime per ore ton will be <br />added. Alkalinity from the Phase 5 enriched pregnant solution will be transferred into the <br />barren solution being applied to Phases I through IV. <br /> <br />Cripple Creek & Victor Gold Mining Company <br />Cresson Project Mine Life Extension <br />7-5
