MINING PLAN EXHIBIT D(CONT) benches that extend from east to west across the stage as shown on the MINING PLAN MAP - EXBIBIT C-1. The typical layout of the bench is show on Figure D-1 following the Mining Timetable . Eventually, an additional 10 acres of partially reclaimed area will be present since reclamation will run concurrent with mining, so the total bonded disturbance allowed will be 40 acres . There will be a 25-foot or wider digline setback maintained from the permit boundary so there is adequate space on the level above the slope for property line access, setback maintenance, grading and shaping. In Stage VI the setback from the northern house will be between 210 and 215 feet and on the southern ranch complex it will vary from 50 to 130 feet. As mining progresses across a stage the exterior slope will be mined 1-� to 1 until it is within 55 feet of a stage perimeter then shaped to the final 3 : 1 rate from the surface to the top of the first bench. Once that slope toe of that slope is established another 55 foot wide vertical mining setback will be established to leave enough material to create the bottom of the 3 : 1 cut/fill slope along the outer limits of a Stage . The Plant Site/stockpile area will start on the surface, but once the initial level is reached it will be moved below grade so it is screened below the surrounding areas . MAP EXHIBIT C-1 shows how the site would look when the mine reaches full production. On the Mining Plan Map the processing/stockpile and partially reclaimed areas covers approximately 22 . 0 acres, there is 15 . 0 ac. of bench and working face area and 3 . 0 acres stripped. The highwall is 500 feet long with approximately 4100 feet being temporary graded to 2h to lv. As the mining face extends across the property, we will maintain a 500 foot long, near vertical, working face . The remaining highwall will be kept at an interim grade of 2h to lv. The working face will move from the top bench to the mine floor as it progresses across a given Stage. The plan is to continue to mine into the sand deposit at the mining face until the permit limits are reached. . Typically mining will be done in cycles . These cycles involve moving a crushing plant into a mine and beginning to process material until there is a six month to 1 year supply of material stockpiled. Once an adequate supply is processed, the processing plant and equipment is moved to another mine . The 6(revised 10.31/19)
