Most of <br /> this material will be able to be placed in its final <br /> locations early in the life of the mine. <br /> Overburden will be stripped from the area to be <br /> mined and sloped back at 2H:1 V above the <br /> margins of the pit highwall. Initially, stripped <br /> h. Overburden overburden will be used to construct permanent <br /> stripping, sediment control structures and the expanded <br /> operations pad near the base of the pit. Excess Y N N <br /> stockpiling, and overburden will be placed in permanent disposal <br /> stabilizing cells north of the pit area. Disposal cells will be <br /> compacted and have slopes no steeper than 2:1. <br /> Overburden cells will be topsoiled and vegetated <br /> with the reclamation seed mix. <br /> The initial steps in mining are drilling and <br /> blasting to break out the rock from the highwall, <br /> then loaders move the pit run to the screen and <br /> i.
