EXHIBIT D MINING PLAN <br /> 1 . General Mining Plan <br /> The property boundary has been surveyed and marked. Map C-2 outlines the mining plan <br /> including the affected area of 159.2-acres, with an average elevation of 4667 ft. above mean <br /> sea level. Sand and gravel will be extracted for use in construction materials such as crushed <br /> rock, sand, washed rock, concrete, and asphalt. There is also the possibility of incidental fill dirt <br /> production. The maximum mining disturbance at any given time will be 50-acres. Exhibit L <br /> outlines the reclamation conditions for this maximum disturbance scenario and the associated <br /> bond. <br /> Access to the mine will be via the existing site entrance located on the southwest end of the <br /> operation connecting to Highway 394. To prevent groundwater infiltration into the pit and <br /> facilitate water storage after reclamation, two slurry walls will be installed around the various <br /> mining areas. <br /> Due to timing of the operation, Phase 1 has already been stripped for the existing operations. <br /> Phase 1 will not be mined but has been included in the area descriptions and tables. Phase 1 <br /> will remain as an industrial operation after mining has completed. Phasing and areas are <br /> described below. <br /> Table D-1 Phasing <br /> Phase Description Approximate <br /> Acreage <br /> 1 Processing&Industrial Area-already developed 20.5 <br /> and in operation.Will remain after reclamation. <br /> 2 Westernmost mining pod. 21.4 <br /> 3 Northern portion of center pod. 18.2 <br /> 4 Southern portion of center pod. 18.2 <br /> 5 Northern portion of eastern pod. 20.8 <br /> 6 Southern portion of eastern pod. 20.7 <br /> Dozers and scrapers will strip topsoil and overburden from mining areas, storing them in <br /> designated stockpiles. Any stockpile remaining for over 90 days will be seeded to prevent <br /> erosion. Sand and gravel extraction will involve loaders, excavators, dozers, and trucks, with <br /> material transported to the southern permit area for processing. While haul trucks are currently <br /> anticipated, there is potential for replacement by a conveyor belt in the future. <br /> Evans Mining Resource <br /> October 2024 Lewicki& Associates <br />
