• <br /> • <br /> SSR <br /> MINING <br /> rinsed in the same manner as previously approved. Two rinsing cycles, using recirculated solution <br /> and fresh water, will require about 30 months to complete. It is proposed this will be followed by <br /> a hydrogen peroxide (H2O2) assisted rinsing cycle, to complete removal of cyanide (the need for <br /> this H2O2 rinse will be evaluated during VLF rinsing). The financial warranty is based on two <br /> standard water rinsing cycles and one H2O2 rinsing cycle over an approximate six-year period. <br /> The rinsing procedure will employ a rinse-rest strategy as previously approved. The VLFs will be <br /> rinsed in segments with portions being actively rinsed while other areas are allowed to "rest." <br /> Rinse water and H2O2 will be circulated using the VLF pumping systems at a pumping rate of <br /> approximately 15,000 gallons per minute. <br /> Rinsing criteria previously approved for the VLFs is an average concentration weak acid <br /> dissociable cyanide (CNwAp) of 0.2 milligrams per liter (mg/L) in the rinse water from meteoric <br /> water mobility testing on representative sampling of the spent ore, or in return flows derived from <br /> the neutralized ore, or both. A seven-year monitoring period will follow the rinsing to demonstrate <br /> compliance with the standard. Physical reclamation of the VLFs will be completed in <br /> • approximately two years and will start concurrent with the monitoring period. <br /> Upon achieving the CNWAD rinsing criteria, the VLF liner systems will be breached in the same <br /> manner as previously approved. The liner will be perforated to prevent excessive accumulation <br /> of stormwater infiltration in the neutralized ore behind the toe berms and to move meteoric drain <br /> down stormwater into the underlying diatreme rock. It is anticipated that a drill rig will be used to <br /> drill from the surface of the ore on the VLFs through the synthetic and clay liners into the closure <br /> drains and underdrains, where appropriate. Holes will be drilled to puncture the liner above these <br /> features installed at several locations beneath the PSSAs. This will allow conveyance of post- <br /> reclamation precipitation through the material on the VLFs and into the underlying diatreme. <br /> Following the achievement of the CNwAD removal criteria for both VLFs and following the <br /> breaching of the liner systems (as discussed above), all down-gradient appurtenances will be <br /> reclaimed as follows. <br /> At both VLFs the pipes, pumps and other structures will be removed from the underdrain collection <br /> systems. The concrete pump-back vault side walls and bottom will be broken up, followed by <br /> burial onsite with surrounding fill material. Ponds will be backfilled with material and re-contoured. <br /> The entire area will then be graded to blend with the surrounding topography, followed by <br /> reclamation of the sites. <br /> • Cripple Creek &Victor Gold Mining Company Exhibit E <br /> Cresson Project Amendment 14 <br /> 14 <br />
