Exhibit D MINING PLAN AND TIMETABLE LOCATION This is an open pit mine located about 1 mile west of Platteville, with the entrance on the east side of County Road 21 just south of 32 . 5 Road. To reach the mine from Platteville, starting at the intersection of HWY 85 and Justin Ave (HWY 66) go west on Justin Ave 2 . 5 miles to Weld County Road 21, then north 1 .37 miles to the entrance. The coordinates of the entrance are 40013125 . 153611, -104052 1 02 . 8563" . Please refer to EXHIBITB-VICINITY MAP for the property configuration and the relationships to sur- rounding geological features . The area to be mined lies between County Road 21 and the South Platte River, straddling 32 . 5 Road and lies within the Town of Platteville, Colorado. GENERAL INFORMATION The primary commodities to be mined are sand, gravel, top- soil, overburden, and borrow materials . No incidental commodi- ties will be produced at this mine. Throughout this application we will refer to the two areas, (a) the south area containing Phases 1 & 4 and (b) the north area containing Phases 2 & 3 . The roadways (transportation corridors) are left out of the permit since L.G. Everist, Inc. does not own them. Permit/affected lands and mining lines and setbacks vary throughout the site, depending on ROWS and proximity to the South Platte River. Along the river the permit/affected lands line is 100 feet from the western bank of the river. Along the river in Phase 2 (north of CR 32 . 5) , the mining line will be 250 feet from the upper river bank. Along the river in Phase 1 (south of CR 32 . 5) , the mining line will be along the west side of the old railroad grade, which is greater than 345 feet from the river bank. Along the County and Local Roads, the permit lines use the ROW lines associated with the roads . Platteville requires 80 feet ROW for CR 32 . 5, and Weld County requires 40 feet, east of the section line, for the ROW along CR 21 . The slurry walls will be constructed 15 feet from the Per- mit/Affected lines or utility ROW lines, whichever is greater. The mining setback will be 25 feet inside the slurry walls . Mining in all Phases will be done after the slurry walls are completed around them so they can be dewatered and mined dry. Dewatering will continue until mining ends in each Phase to re- move any stormwater or leakage that accumulates in the mining L.G. EVERIST, INC-WEST FARM RESERVOIRS November 2022 4
