~11 ~ ±~ <br />SMITH WILLIAMS CONSULTANTS, INC. <br />• <br />Cripple Creek & Victor Gold Mining Company <br />Cresson Project <br />Valley Leach Facility <br />Phase 5 Extension Design <br />1.0 Introduction <br />Cripple Creek & Victor Gold Mining Company (CC&V) operates the Cresson Project, located in <br />Teller County, Colorado, near the city of Victor. The Cresson Project is a mining and ore <br />processing and beneficiation facility that is composed of surface mines as well as a valley leach <br />facility (VLF); an adsorption, desorption, and recovery (ADR) plant;-and associated <br />infrastructure, all of which were designed and constructed to meet or exceed the requirements <br />established by CRS §34-32-101 et seq. and regulations promulgated there under by the Mined <br />Land Reclamation Board (MLRB). <br />The existing Cresson Project was constructed in phases from 1994 through 2004 (Phases I <br />through IV). Phases I and II were permitted in 1994 and constructed during the 1994 through <br />. 1996 construction seasons. Phase III was permitted in 1999 and construction was initiated the <br />same year, with completion in-2000. Phase IV was permitted in 2000 and construction was <br />completed in 2004. CC&V is proposing to further extend the ore beneficiation operations to <br />accommodate additional ore reserves identified within the mine areas. This report presents the <br />design for the proposed addition of approximately 6.4 million (surface area corrected for slope) <br />square feet of lined leach area to the north and east of Phase IV, in an area referred to as Phase 5. <br />This area encompasses a portion of Squaw Mountain and the Arequa Gulch Overburden Storage <br />Area. - <br />Additionally, CC&V is proposing to increase the maximum depth of stacked ore on Phase I <br />through Phase IV VLF to 800 feet above the lined surface. Ore stacked within the Phase 5 VLF <br />will have a maximum depth of 590 feet. In addition, the Phase 5 VLF extension includes a new <br />dedicated PSSA. <br />This report presents the geotechnical data and analyses.for the Phase 5 VLF extension.
