EXHIBIT D MINING PLAN(corm) the Mining Plan Map, so importing material would not be needed to complete disturbed slope areas . The "direction of mining" arrows on MAP EXHIBIT C-1 - MINING PLAN MAP show the applicant 's best guess on how mining will progress through the mine area at this time. Natural ground conditions and unforeseen circumstances may necessitate changes to the mining direction throughout the life of the mine. The RECLAMATION COST ESTIMATE-EXHIBIT L is based on an estimated disturbance area when the mine has been open for a few years . The acreage disturbed may increase or decrease as mining pro- gresses . If it increases, a Technical Revision will be filed to adjust the bond amount to cover the changed cost estimate. Initial mine development will begin on the southwest side embankment just east of the entrance on HWY 85. The plan is to use portable processing equipment located next to the working face and limit the plant site/stockpile areas to a minimum and produce only what can be used over a month or more. Most of the material will be used inter-company with a few outside sales so large stockpiles of material are not needed. The topsoil and overburden will be stripped and stockpiled around the mining area. Some of this material will be used to construct a sight berm along the HWY 85 corridor to limit visi- bility from the highway into the active mining and processing areas. Any material not used for the sight berm construction will be stockpiled on the north and east sides to have for build slopes. The berms will vary in height depending on the area to be screened, with 3: 1 slopes on each side. As mining progresses and backfilling begins some of the overburden and topsoil may be placed on the backfilled area to avoid having to handle it twice. Operations will begin by stripping an approximate 5 acres. This will allow mining to start into the gravel slope along the southwest side of the sand and gravel deposit . A portable pro- cessing plant will be setup where mining begins and the material will be stockpiled in the immediate area for use as needed. The plant may run sporadically depending on the companies need for material. Periodically as mining progresses the stripped area will be extended so there is approximately two (2) acres ready for min- ing, and 2 acres of stockpiled material and 6 acres being back- filled for a total of 10 acres . All topsoil will be kept sepa- rate from the overburden when stockpiling. Overburden and top- soil will be stored around the mining area for use in reclama- tion. These stockpiles will be placed strategically in progres- sion with mining, and in some cases the topsoil and overburden 8 1/2 Enterprises LLC. December 9, 2025 Sasaki Pit 10
