Naturally, it is impractical or impossible to return original contours to these areas. Over-all slopes on solid rock sections of the Open Pit are approximately 1 :1 with bench slopes approaching a new vertical rise. Other areas within the pit that are composed of a crumbly rock (west of ,' Mosquito fault) or that appear as talus due to subsidence from underground mining are at the angle of repose , approximately Within the Open Pit where it is likely that a free forming water pool may develop, it is not practical to provide a ��t ~! grade no steeper than 3 : 1 within 5 feet above to 10 feet below a .// 1, water line because the ultimate water line presently cannot be anticipated . 'Therefore , Climax Molybdenum Company requests from fthe 'Reclamation Board a variance to this 15ar-ticular reclamation ';. standard . The rock waste slopes of McNulty Dq p_will have an overall slope of 3 :1 near the base and approximately 2: 1 elsewhere . Some bank slopes of waste rock dumps existing naturally at 1 . 5 : 1 will partically be reshaped in the range 2 :1 to 10-3
