A series of liner load tests conducted by Golder (2005) indicate that the liner system <br />within the SGVLF can withstand the proposed ore depths of up to approximately 800 <br />feet, or approximately 610 pounds per square inch ( "psi ") assuming an ore density of 110 <br />pounds per cubic foot ( "pcf'). <br />Further information about the ore storage area liner system is located in Appendix 9, <br />Volume V. <br />7.2.1.3 Pregnant Solution Storage Area Liner System <br />The PSSA will be constructed as an internal pond within the SGVLF area. The PSSA <br />will be formed by constructing a containment embankment across the Squaw Gulch <br />drainage. This embankment serves as the toe of the SGVLF and provides foundation for <br />realignment of a portion of SH 67. <br />The liner system for the PSSA will be similar to the existing PSSA liner for the AGVLF <br />and will consist of the following: <br />• Outside of the PSSA sump, the liner system will consist of 12 inches of SLF <br />overlain by a 100 -mil textured (single -sided with the textured side down) <br />LLDPE bottom geomembrane overlain by 3 feet of low volume solution <br />collection system ( "LVSCS ") fill overlain by a 100 -mil smooth LLDPE top <br />geomembrane overlain by 2 feet of DCF. A textured geomembrane was <br />selected for the bottom liner as it provides for higher interface shear strength <br />than smooth LLDPE geomembrane. <br />• Inside of the PSSA sump, the liner system will consist of 12 inches of SLF <br />overlain by a 100 -mil textured (single -sided with the textured side down) <br />LLDPE bottom geomembrane overlain by 3 feet of LVSCS fill overlain by a <br />100 -mil smooth LLDPE top geomembrane overlain by 5 feet of DCF. <br />Installation of the composite liner systems will generally be on slopes of2.5H:1 Vor <br />flatter. Additional details are provided in Appendix 9, Volume V. <br />7.2.1.4 High Volume Solution Collection System <br />The HVSCS provides a means to collect and route process solutions from the ore storage <br />area to the PSSA. The HVSCS for the SGVLF will be similar to the system approved <br />and certified for the AGVLF. It will consist of 24 inches of free draining DCF, <br />Cripple Creek & Victor Gold Mining Company <br />Cresson Project Mine Life Extension 2 <br />7 -5 <br />
