EXHIBIT D MINING PLAN (coNT) placed into the five (5) settling ponds/overburden backfill Phases shown on the MAP EXHIBIT C-1 - MINING PLAN MAP, or removed from the site . The soils on the permit area that will be salvaged and replaced should be capable of growing vegetation consistent with what is required by the Reclamation Plan. The average depth of topsoil on the site according to the NRCS report and site investigations is 0 to 12 inches deep. Enough topsoil will be retained to place an average of 6-12 inches on the areas to be revegetated. As each area is stripped, L.G. Everist will determine how much soil will be needed to reclaim the area and it will be stockpiled for use in reclamation. Over the life of the mine, an estimated 816 , 000 yards of topsoil will be stripped from the mined area but, a minimum of 241, 500 yards will be retained for resoiling the areas to be revegetated. In addition, there is from 0 to 3 feet of overburden on most of the site . Much of this overburden will be retained and used to backfill the areas shown on the maps or removed from the site. The topsoil and overburden stockpiles will be located around the excavation, typical piles in possible location are shown on the MAP EXHIBIT C-1 - MINING PLAN MAP. If the soil stockpiles remain undisturbed for more than one year, a cover crop of the approved seed mix, at the rate called for in the Reclamation Plan, will be used to revegetate them. MINING PLAN MAP EXHIBIT C-1 - MINING PLAN MAP shows the approximate direction of mining as it progresses across the site . The plan is for having 180 acres ± of disturbance bonded to allow for flexibility during mining. This 180 acre area will include stripped, partially mined, partially reclaimed, Plant Site, materials stockpile area and future reservoir areas . As mining progresses across the property some parts of the property will remain undisturbed while other areas will be either, stripped, mined, partially reclaimed or totally reclaimed. The MAP EXHIBIT C-1 - MINING PLAN MAP shows how the area will look when approximately 23% of Phase 2 , and all of Phases lA and 2A are mined and partially refilled. Note how the final slopes around the perimeter of Phase 2 are created as mining progress by leaving undisturbed material in the slopes . So only the working face area would need to be shaped, and 20 acres would need to be resoiled, if mining ended at this time. Also in this snapshot in time, the reclamation in Phase 1 would be complete, and Phase 3 would be Plant Site, equipment storage and stockpile area. Of the 643 . 30 acres ± in the permit area, approximately 508 acres ± will be disturbed by mining. This mining plan details the L.G Evenst,Inc. Ragsdale Reservoirs May 5,2020 8
