Exhibit D - MINING PLAN <br /> Native/Pierre Mine is located in horizontally bedded buff, gypsiferous Pierre shale of lower Cretaceous <br /> age. <br /> The current operator of this clay mine began this operation in 1915 and has continuously mined to date. <br /> The mining method as approved, in the 1977 permit is similar; the only changes are the utilization of <br /> more modern efficient equipment. The primary reason for this conversion is to add approximately 24 <br /> acres to the permit area that covers the reserves leased or owned by Summit Brick and will extend the <br /> life of the mine.The additional area has been owned by the current owners for the purpose of mining <br /> since approximately 1915. <br /> The primary commodities to be produced are clay and a sand borrow material. There are not any <br /> incidental products created. The entire mining sequence is in the Pierre Shale formation. The ore body <br /> consists of clay and sand with the sand typically overlying the clay. Depth from the surface to the top of <br /> the clay/sand will vary from 1' to 5'.The usable clay varies from 0'to 15'thick. Maximum pit depth may <br /> reach the 20-foot range but average depth will be less than 15 feet. <br /> Mining will be accomplished using a dozer, loader and/or scraper depending on the distance the <br /> material is to be moved. As mining progresses through the mining area, all available topsoil will be <br /> removed, and will either be spread over areas previously graded to final slope or will be stored for <br /> future application. The overburden will then be removed and used as backfill or will be stockpiled where <br /> it will not be mixed with the topsoil. The exposed clay and/or sand is then mined and stockpiled on the <br /> pit floor of a previously mined area. The mined slope along the permit boundary will be 3H to 1V or <br /> flatter, while the working face slopes in the interior of the permit boundary will be a maximum of 0.5 H <br /> to 1 V. No blasting will take place at this mine. <br /> The stockpiled material is then transported to the nearby brick plant by truck. <br /> Mining operations including the truck traffic at this pit are intermittent and typically occur in less than <br /> 30 days of the year and only as this clay type is needed by the brick factory. Activity usually occurs <br /> monthly. <br /> Map Exhibit C shows the current permit area and the area being added to the permit. Mining to date has <br /> utilized nearly all the Eastern Portion of the existing �10 Permit. <br /> Map Exhibit C-1 shows the next stage of mining consisting of the active processing and mining area and <br /> a released reclaimed area. Note that, a portion of the area will be in the final stages of reclamation as <br /> mining progresses thru the mine. The maximum extent of disturbance for the processing and mining <br /> area will not exceed 10.0 acres. Mining will progress into addition area to the west only after a like sized <br /> area is reclaimed and released. <br /> This will stay a dry mining operation of clay. Except for dust suppression, no water usage is anticipated <br /> at the mine site and no surface or ground water is retained. Surface water will be diverted around the <br /> affected area. A sediment basin will be maintained for storm water runoff. Stormwater will not be <br /> retained for more than 72 hours in this basin before it is released. <br /> Summit Brick&Tile Company - Native/Pierre Mine 6/24/2020 <br /> 6 <br />
