• MINING PLAN EXHIBIT D <br />• <br />• <br />1. General Mining Plan <br />The property boundary has been surveyed on site and the permit area will be surveyed and marked <br />prior to any site disturbance. Map C-2 shows the mining plan. <br />The access to the site will be from County Lane 15, which approaches the site from the north. The <br />gravel deposit is mostly flat with 0 to 4 inches of topsoil, 6 to 10' of overburden, and gravel <br />thickness of approximately 20 feet. It is underlain by approximately 30 feet of Pierre Shale. Both <br />the gravel and the shale will be mined year around, but in varying quantities depending on <br />demand. <br />Topsoil will be salvaged from all Mining Areas. The expected thickness of topsoil is <br />approximately 4 inches. Gravel will be mined and taken to the crusher/screener by the loader. <br />Mining will be conducted in five phases, which minimizes disturbed area and allows reclamation <br />to take place concurrently with mining. Mining will proceed from the current mining area, north <br />into the additional acreage. Stockpiles will be placed within the previously mined area to minimize <br />disturbance areas. Once ample room is created within the current pit, the overburden that is <br />encountered will be placed within this area. As mining progresses into the new area to the north, <br />overburden encountered will be used to reclaim previously disturbed area. The direct placement of <br />this overburden reduces the cost of mining and eliminates work that will be needed during <br />reclamation. This allows the total disturbed area to be as small as possible. Volumes of material <br />are shown in Table D-1 Mining Area Material Table. The mining areas and stockpiles are shown <br />on Map C-2. <br />Korinek 91 Pit August 2009 <br />D-1
