MINING PLAN EXHIBIT D (coNT) <br />overburden slopes will be 3 : 1 . MAP EXHIBIT C AND EXHIBITS contain <br />information on all structures within 200 feet of the mined area. <br />This mine will be operated as a single staged operation <br />beginning on the southwest corner of the site in the old mine <br />cut. The rock is a solid deposit of igneous rock that averages <br />25 feet thick and in its natural state is not suspectable to <br />erosion. This hard rock deposit is stable when left nearly <br />vertical as is evident in the old mine areas. The depth of the <br />deposit will not require benching to remain stable when not being <br />actively mined. <br />From this point mining will progress to the north and east <br />leaving a gently sloping floor and a working face that stretches <br />across the mined area. The working face will increase in height <br />from the outer edges of the rock deposit to the center of the <br />mine where the rock is the deepest. Mining will progress into <br />the hillside at this level until the exterior edges of the <br />deposit daylights out the sides or mining reaches the mine <br />boundary. The MINING PLAN MAP shows how this will look as mining <br />begins to reach the north /south mine limits. Note that the mine <br />floor is being reclaimed as mining moves from west to east. <br />The topsoil /overburden will be stripped from the top of the <br />rock in an area cover approximately 3.0 acres, segregated into <br />like material stockpiles and placed along the north perimeter of <br />the stripped area. Once this is complete, drilling will begin <br />and the first charges will be set. The rock will be placed in <br />haul trucks using a trackhoe or front -end loaders and delivered <br />to the Plant Site - Stockpile Area on the ease side of the mine. <br />Mining will progress in this fashion until all material has <br />been removed. As the floor area enlarges, any areas that will <br />not be disturbed again will be reclaimed. The MINING PLAN MAp shows <br />how we believe the site will look when mining has reached the <br />final floor elevation and the face stretched across the property <br />from south to north. MSHA safety berms will be placed along the <br />exterior of the mine floor during mining. <br />As mining advances across the property we expect the over- <br />burden depth to increase as it approaches the hill on the central <br />part of the site. At this time we have not determined if it will <br />be economical to strip more then 15 feet of overburden from the <br />rock or whether the hill contains material that we may be able to <br />sell. For this reason we have developed two mining options as <br />7 <br />
