MBiIWa RAW EXHIBIT D (CONT) <br />Initially the existing road will be used to access County <br />Road 60 in the northeast part of the site. Once gravel produc- <br />tion begins and a plant site has been established construction <br />and excavation of the new entrance will begin from the inside out <br />creating a rang from the mine floor to the county road. This new <br />ramp will slope down to the southwest and will intersect County <br />Road 60 at the 8100 elevation. This ramp will be oriented down an <br />existing draw. Finally, once traffic can be routed on the new <br />ramp, the original ramp in the northwest corner of the pit will <br />be mined out to ultimate pit limits. <br />Frontend loaders, haul trucks and scrapers will remove <br />material from the working face and floor of the mine. It will be <br />hauled to the processing plant and stockpiled for feeding the <br />plant. <br />Mining will begin in the central part of the property near <br />the old mine where a plant site will be established. Mining with <br />then advance to the north at an elevation intended to create a 50 <br />to 60 foot face. This will mean excavating a temporary floor at <br />and elevation of approximately 8195. The mining will progress <br />into the hillside at this level until the exterior slope area is <br />reached. The Mining Plan map shows how this will look as mining <br />begins to reach the souther limit. Note that the slope along the <br />east and west sides are mined as we go. Once the northern mining <br />limit is reached, we will reverse direction and begin to mine to <br />the south creating a face that extends to the final mine floor <br />elevation. Again the exterior slopes will be mined to their <br />final rate as mining progresses. In effect this will have <br />created a split level mining plan that avoids an excessive <br />highwall by splitting it in half. <br />The near vertical face will be worked across the property <br />except where it begins to approach the exterior slopes. In the <br />slope area the face will be mined to it final rate of 3:1. This <br />will leave native material for the slope base and assure the <br />stability of the slope when mining ends. Some backfilling of the <br />slope may be done if excess overburden is found as mining pro- <br />gresses. initially the site will be like a big bowl. The intent <br />is to leave most of the gravel hillside along the road to create <br />a sight berm that will remain in place until the very end. <br />Processing and mining will take place behind this berm and <br />surface water flow can be retained in this area. When the mine <br />limits are reached on the north, east and south, the sight berm <br />7 <br />
