c. Ore Slopes above the Pregnant Solution Storage Area (PSSA) is 2.5(H):1(V), a bench <br /> with a minimum width of 55' is required between the crest of the lower lift and <br /> the toe of the new lift. <br /> d. Ore slopes above the Mill Platform were designed to be 2.0(H):1(V), a bench with a <br /> minimum width of 30' is required between the crest of the lower lift and the toe of <br /> the new lift. <br /> 2) Lift transitions:Based on review of the TR submittal and discussions with CC&V personnel on site on <br /> May 23, 2018, there is an omission in this TR regarding ore stacking during the transition to a new <br /> lift. Please provide a plan for the transition to new lifts. <br /> 1.a <br /> 1 <br /> PROPOSED4 <br /> °`100'' 'VARIESBASED ON ° <br /> PAD SLOPE <br /> 1 2' DGF OVER 80 mil DOUBLE <br /> °•< :c �� . 2 MA) SIDED TEXTURED LLDPE <br /> 20% GEOMEMBRANE AND 1' OF SLF <br /> 0RE <br /> °0 n <br /> ep <br /> As shown in the figure above,the total lift height in the very small transition section varies between <br /> 111.8' and 120',depending on the slope of the pad. The ore being placed is contained inside a "v" <br /> section against the edge of the pad which prevents the ore from traveling down the slope in an <br /> uncontrolled manner. <br /> 3) Material tracking and placement: There appears to be generally four classifications of material to be <br /> placed on the VLF: crushed ore, ROM < 3 inches, ROM > 3 inches, and tailings. As there are <br /> different criteria for the placement of each of these materials, please describe how the mine tracks <br /> these various materials source and placement on the VLF to ensure these criteria are met. <br /> CC&V employs an Ore Control group which designates all material types and routing. <br /> Subsequently,material is classified and routed to an appropriate location as described in the VLF2 <br /> Ore Stacking Guidelines,submitted as Attachment 1 to TR103.Based on the stacking plan,each <br /> haul truck operator is given a load location assignment through Minestar.Once the load is <br /> delivered,the final dump location data is recorded.The final stacking location and material <br /> designation data is tracked through the MineStar Mining Management System. <br />
