MINING PLAN EXHIBIT D <br />1. General Mining Plan <br />The permit area will be staked prior to any additional site disturbance. Map C -2A shows the <br />configuration of the site after mining has progressed through mining Area 4. This map also <br />displays the visual buffer berm left as Mining Area 5. Map C -2B shows the configuration of the <br />fully mined out pit as well as the location of the processing plants, stockpiles and office /shop <br />area. The plan shows that mining will be done in 5 phases: Mining Areas 1 through 5. Mining <br />Areas 1 through 4 contain the majority of the gravel resource and Mining Area 5 is used to retain <br />the visual buffer to the end of mining. Processing of the gravel will be conducted within Mining <br />Area 1 as shown on Map C -2B. The gravel will be excavated and hauled to the crusher with a <br />loader. Mining will progress in order starting in Mining Area and finishing in Mining Area 5. <br />Access to the mining area will be from a new access road starting a T Road on the west side of <br />the West Canal, traversing up the side of the terrace and ending in Mining area 1. This access <br />Road is shown on Map C -2A. The access road will be approximately 24 feet wide travel surface <br />with a small v- shaped drainage ditch on any cut slope of approximately 1.0 feet depth. The <br />crossing of the Ouray Ditch will be in a 24 inch diameter culvert, which is the same size as all <br />other crossings of the Ditch in the surrounding area. The access to the shop and office area is <br />directly from T Road. The anticipated haul route will be west on T Road and then north or south <br />on Highway 550 depending on the location of the project. There is minimal overburden on site, <br />but it averages at approximately 1 foot thick with 1 foot of topsoil above the overburden. The <br />loose gravel deposit is very uniform at approximately 25 -35 feet thick. The deposit tapers out as <br />the terrace transitions from the flat top to the side slopes. Below the loose gravel deposit is shale <br />which is exposed on the side slopes of the terrace. <br />Topsoil will be salvaged from all Mining Areas. The expected topsoil thickness is 12 inches. <br />Initially, topsoil will be stockpiled in the southwest corner of the permit area (See Map C -2A) in <br />Topsoil Stockpile 1. Approximately 77,000 cubic yards of topsoil from Mining Area 1 will be <br />stockpiled here. The topsoil in this stockpile will be used for reclamation. All other topsoil will <br />be salvaged and directly replaced on areas that have been previously excavated. The operation <br />will mine for a few months per year and produce stockpiles to last the remainder of the year. <br />Uncompahgre Pit, February 2013 D -1 <br />
