EXHIBIT D -Mining P)an <br />The mining plan will be: <br />a) Commence mining along the northwest corner of the SW 1/4 of Section 10, then <br />proceed east. Topsoil will be stripped and stockpiled for later use in reclamation of the <br />pit. The mining of gravel will take place as soon as the topsoil is removed. This effort <br />will be accomplished primarily by bulldozers, scrapers, and front-end loaders. The <br />material will be hauled from the site in trucks. Mining will take place in 20-acre phases <br />beginning at the NW corner of the quarter. The N 1(2 of the SW 114 and the SW 1(4 of <br />the SW 1/4 of Section 10 will be mined before any mining occurs in the SE 1/4 of the <br />SW 1/4 of Section 10. All walls around the outside of the quarter will be left at a slope <br />no greater than 4:1. <br />b) Material will essentially be loaded and removed as it is mined. Stockpiling may <br />occur, allowing material to simply be loaded and hauled at a later date. No additional <br />processing of material is anticipated at the site. <br />c) There will be no water diversions created by the mining efforts. There is currently <br />no intermittent drainage across the property. Since the ultimate plan for the 1/4 will be a <br />large grassland area, which is significantly lower than surrounding property, two ponds <br />will be left to collect drainage from large rainfall at the site. One pond will be left in <br />phase 1 in the northwest corner. The second pond will be left in phase 7 in the very <br />southeast corner. These ponds correspond with the current natural drainage off the <br />property during a large rainstorm. They will collect water for cattle, as returning the site <br />to grazing is the ultimate plan of reclamation. <br />d) The open portion will be fairly small, allowing the operator to concentrate on <br />mining one area at a time, then moving on to the next mining segment. <br />e) It is anticipated that with limited use of the pit, each 20 acre segment may last as <br />long as 5 years, giving a total pit life of up to 40 years. <br />(i) The operator will work on a fairly small segment of the existing phase as <br />material is needed. Time periods are difficult to estimate since the pit is only used on a <br />limited basis. <br />(ii) The Road Foreman will determine the actual location and size of the working <br />area, depending on how much material is needed at the time. The excavation will simply <br />work in a west to east pattern, proceeding from north to south. <br />(iii) Each new working segment will be stripped of topsoil and overburden before <br />mining of the gravel occurs. <br />f) Additional information on Exhibit C (Mining Map) shows the following: <br />
