MINING PLAN <br />1. General Mining Plan <br />EXHIBIT D <br />The permit area will be staked prior to any additional site disturbance. Map C-213 shows the <br />mine plan. The plan shows that mining will be done in 3 phases: Mining Areas 1, 2 and 3. <br />Processing of the gravel will be conducted within the product stockpile and processing area <br />shown on Map C-213. The gravel will be excavated and hauled to the crusher with a loader. <br />Mining will progress from Mining Area 1 to Mining Area 2 and finish in Mining Area 3. <br />Access to the permit area will not change. The site has a gated access to Sundown Road. The <br />anticipated haul route is shown on Map B-1. There is minimal overburden on site, but it averages <br />at approximately 1 foot thick. The loose gravel deposit is very uniform at approximately 12 feet <br />thick. Below the loose gravel deposit is a conglomerate gravel deposit with an approximate <br />thickness of 2.5 feet, which can also be used for road base. The overall deposit to be mined is <br />approximately 14.5 feet thick. Below the conglomerate is shale. <br />Topsoil will be salvaged from all Mining Areas. The expected topsoil thickness is limited to <br />approximately 6 inches. Initially, topsoil will be stockpiled in the northeast corner of the permit <br />area (See Map C-213). Approximately 3,549 cubic yards of topsoil from Mining Area 1 will be <br />stockpiled. The topsoil in this stockpile will be used for reclamation. All other topsoil will be <br />salvaged and directly replaced on areas that have been previously excavated. The operation will <br />mine for a few months per year and produce stockpiles to last 1-2 years. Crushed product will be <br />stored within the product stockpile and processing area. See Map C-213. All final slopes will be <br />mined to 3H:1V to reduce the amount of reclamation required after mining. The overburden will <br />not be stockpiled but directly replaced on the pit floor as it is mined. The mining areas and <br />stockpiles are shown on Map C-213. <br />Moonscape Pit, July 2009 D-1
