• <br /> • SSR <br /> MINING <br /> 2 EVALUATION OF PROJECT COMPONENTS <br /> The Cresson Project activities associated with Amendment 14, and other ongoing operations <br /> associated with the Cresson Project, meet the requirements of a DMO discussed above. CC&V <br /> uses certain chemicals in the gold recovery process and exposes materials through mining that <br /> have potential for acid generation. Such chemicals are presently in use within the areas of the <br /> Valley Leach Facilities (VLFs), High Grade Mill (HG Mill), Process Solution Enhancement System <br /> (PSES), and the Adsorption, Desorption and Recovery (ADRs) facilities exclusively. The HG Mill <br /> Building and associated infrastructure will be decommissioned and demolished prior to <br /> commencement of Amendment 14 construction activities (VLF2 Phase 4), anticipated in 2025. <br /> Information related to the Mill facilities, including chemical use and storage, is included in this <br /> Exhibit to describe the environmental protection protocols used until and through <br /> decommissioning. <br /> Currently there are no plans to recommission the HG Mill prior to the commencement of <br /> • construction of the VLF2 Phase 4 expansion. Notifications will be submitted to DRMS if a restart <br /> of the HG Mill is anticipated. <br /> The chemicals in use at the Cresson Project and stored for use within the VLFs, ADRs, Mill <br /> facilities, and underground operations are listed on Table U-1, which includes information on the <br /> chemical use, typical storage volumes, and the fate of the chemical. There are no proposed <br /> changes to chemicals used or dosage rates in Amendment 14. <br /> • Cripple Creek&Victor Gold Mining Company Exhibit U <br /> Cresson Project Amendment 14 <br /> 2 <br />
