• <br /> • SSR <br /> MINING <br /> DESIGNATED CHEMICAL(S)AND MATERIAL(S) HANDLING <br /> Final closure of the VLFs will include double rinsing of the ore with recirculated solution from the <br /> VLFs, followed by a hydrogen peroxide-assisted rinsing cycle, if needed, to complete removal of <br /> sodium cyanide, as described in Exhibit E. As a result of recirculation and rinsing, associated <br /> process equipment will be rinsed and rendered suitable for demolition and salvage. The Mined <br /> Land Reclamation Board (MLRB) has approved a standard of an average concentration of weak <br /> acid dissociable cyanide (CNWAD) less than 0.2 mg/L in the rinse water or in results from meteoric <br /> water mobility testing of the neutralized ore material. Data supporting achievement of this <br /> standard will be provided to the DRMS for review and concurrence. Following concurrence, <br /> physical reclamation of the VLFs will proceed. <br /> The HG Mill facilities will be decommissioned prior to construction of the VLF2 Phase 4. <br /> Chemicals associated with the HG Mill will be removed as part of facility demolition. Rinse water <br /> from decontamination of the equipment will be recirculated into the VLF through makeup water. <br /> The pH modifiers and dilute sodium cyanide solutions also will be recycled through this process. <br /> During periods of temporary cessation, adequate staffing will be maintained to continue to <br /> • circulate solutions and monitor and maintain water balances associated with the VLFs. Power <br /> and emergency back-up power will be maintained. Monitoring and associated reporting activities <br /> also will continue during temporary cessation. <br /> • Cripple Creek&Victor Gold Mining Company Exhibit U <br /> Cresson Project Amendment 14 <br /> 8 <br />
