EXHIBIT D <br />LUSK PIT #36 <br />MINING PLAN <br />A Material will be moved by front-end loaders and trucks. A bulldozer will be used <br />in location where loader is impractical due to loose footing. The maximum depth <br />of the mine is not expected to be lower than the north side of the area (mined area <br />is a ridge). The strata directly below is generally rock and will not be disturbed. <br />B The overburden will be moved by front-end loader and bulldozer and will be <br />stockpiled for use in reclamation. <br />C There will be a water diversion berm constructed on the north side of the entrance <br />road in order to insure that no erodible mat is washed onto non-permitted area. <br />No other berms for erosion control are expected to be necessary. The diversion <br />berm material will be used in reclamation and will not exist after final <br />reclamation. <br />D The area to be disturbed at any one time should not exceed twenty (20) acres. <br />After ten (10) acres are mined, five (5) acres will be reclaimed. By the time we <br />have mined a total of fifteen (15) acres, the original five (5) acres should be <br />reclaimed, and we can start to reclaim another five(5) acres. <br />E 1 Mining will start when permit is received and will continue on an <br />as-needed basis. Material to be mined is primarily caliche of varying <br />depth, with up to 8 (eight) inches of topsoil overburden. <br />2 Reclamation will be an ongoing process as the site is mined. <br />3 Mining and reclamation will be continued until supply of usable material <br />is exhausted. <br />4 Active mining will move in an eastwardly direction at the site and <br />reclamation will begin in the exhausted area. <br />5 Six (6) inches or more of topsoil will be pulled from the stockpile at the <br />pit site. <br />6 Reclamation will proceed as mining moves toward the East with the <br />topsoil stored on-site to be moved back over exhausted area, the ground <br />sloped 3:1 or flatter where necessary and planted back with native grasses. <br />The mixture of grass planted will be 20% Sideoats, 30% Western Wheat, <br />20% Blue Grama, and 30% Buffalo Grass. We will plant 7 to 10 lbs/acre <br />on land being reclaimed. The pit floor will also be re-vegetated.
