Construction techniques proposed for the SGVLF also are the same construction techniques that <br />have been used at the AGVLF. The design and construction of the SGVLF are discussed in <br />subsequent sections. <br />The design and layout of the SGVLF were developed to achieve several key objectives: <br />• Provide a geotechnically stable layout such that acceptable slope stability factors of <br />safety could be achieved during operations and post closure <br />• Develop an effective remediation program for the underground workings and unsuitable <br />soils located within the SGVLF footprint area <br />• Provide adequate capacity for ore reserves within a lined containment area with the same <br />level of protection as the existing AGVLF <br />• Provide adequate containment for process solutions within the PSSA <br />Construction of the SGVLF will be staged over about five years, beginning in 2012 and will <br />occur in two phases. An initial embankment will be constructed at the toe of the SGVLF to <br />provide an area for construction of the SGADR and PSSA and facilitate realignment of SH 67. <br />Based on topographic affects on the ore stacking plan and the designed minimum leach block <br />area, the maximum ore height is proposed at approximately 700 feet, while the design allows for <br />a capacity of up to 800 feet of ore loading. The overall side slopes around the perimeter will be <br />1.6H:1 V, with the exception of the area upgradient of the PSSA toe berm (2.5H:1 V) and the <br />SGVLF area above the High Grade Mill facilities platform (2.0H:1 V). <br />Operation of the SGVLF will include placement of crushed ore and agglomerated ground <br />product from the High Grade Mill facilities. Agglomerated ground product will not be placed <br />within 25 feet of the crest of any ore lift to minimize the potential for localized ore sloughing <br />close to the ore face. <br />Access roads have been incorporated into the design of SGVLF where possible to provide for <br />small truck traffic access around the perimeter of the SGVLF and construction roads within the <br />SGVLF area. An 80 foot wide haul truck ramp was included to provide access from the LOB to <br />the toe of the SGVLF for construction access. <br />As part of the SGVLF design, a water balance was conducted to evaluate the volume of solution <br />that will be generated as a result of the operation of the SGVLF. The water balance model <br />accounts for normal operating volume, solution accumulation due to seasonal climatic variations <br />Cripple Creek & Victor Gold Mining Company <br />Cresson Project Mine Life Extension 2 <br />7 -2 <br />
