Construction of the SGOSA <br />The SGOSA will continue to be constructed in much the same manner as previously <br />approved under MLE although the final configuration has been modified as part of <br />MLE2. <br />The SGOSA overburden is placed in lifts that are, initially, up to about 300( ±) feet high, <br />with benches of appropriate width for erosion control and access during development. <br />This configuration facilitates final grading to achieve slopes that accommodate <br />reclamation. The approximate final reclamation slopes are shown on Drawing F -1. <br />These are shown as overall average slopes of 2.5 horizontal:1 vertical (2.51-1:1V). <br />As currently approved, actual slopes may vary from 2.5H:1 V. CC &V's grading <br />operations typically produce a combination of slopes that compliment the existing <br />topography of the area, and which achieve an overall slope of 2.5H:1 V. Steeper slopes <br />between 2.0H:1 V and the angle -of- repose (generally 1.3H:1 V) will be employed in areas <br />where necessary and appropriate to blend in with the adjacent, non - disturbed terrain or <br />serve to better emulate native terrain, and when they meet the following criteria: <br />• Geotechnically stable <br />• Erosionally stable (sediment is not transported past the footprint of the area in <br />quantities greater than surrounding terrain - based on routine observations and <br />sediment control management practices under the standard operating practices of <br />CC &V) <br />• Can be reclaimed, or covered with talus -like rock <br />• Safe for approved post- mining land uses <br />Construction of the Mill Platform within the SGOSA <br />A new High Grade Mill platform will be constructed adjacent to the SGVLF to process <br />the higher grade ore. To provide the space for construction of the High Grade Mill <br />facilities, an area within the SGOSA will be prepared as the mill platform. The mill <br />platform, shown on Figure C -4 will be located on a portion of the SGOSA. The platform <br />will be approximately 15 acres in size with dimensions of 1,000 ft by 600 ft. Material to <br />achieve the OSA elevations for the High Grade Mill facilities is currently being placed <br />under the approved SGOSA design. The mill platform, shown on Figure C -4, will be <br />located within the currently approved footprint of the SGOSA. Additional details for the <br />High Grade Mill facilities are contained in Section 6.0. <br />Cripple Creek & Victor Gold Mining Company <br />Cresson Project Mine Life Extension 2 <br />5 -18 <br />
