EXHIBIT D MINING PLAN (CONT) <br /> BEGINNING OF UPDATED MINING PLAN <br /> LOCATION <br /> This is an open pit mine located about 3 . 5 miles north of <br /> Fort Lupton, Colorado, with the entrance on the west side of <br /> State Highway 85 . To reach the mine from the Ft . Lupton, go <br /> north on HWY 85 about 3 . 5 miles to Weld County Road 20 . The <br /> coordinates of the entrance are 40°07 ' 50 . 49211, -104048 ' 39. 076" . <br /> Please refer to EXHIBITB-VICINITY MAP for the property configuration <br /> and the relationships to surrounding geological features . The <br /> area to be mined lies north of this point on the west and east of <br /> sides of HWY 85 and Union Pacific Railroad (UPRR) . <br /> GENERAL INFORMATION <br /> The primary commodities to be mined are sand, gravel, <br /> topsoil, overburden, and borrow materials . No incidental <br /> commodities will be produced at this mine . Throughout this <br /> application we will refer to the two areas, (a) the west area <br /> containing Phases 1, 2 & 3 and backfill areas, and (b) an east <br /> area containing Phases 4, 5 & 6 and the backfill areas east of <br /> the railroad. <br /> The western area is made up of four (4) mining areas - three <br /> areas will be mined and reclaimed as developed water storage <br /> reservoirs and one area will be mined, backfilled and reclaimed <br /> as cropland. The eastern area will have up to eight (8) mining <br /> areas, of which five (5) areas will become reservoirs and 3 areas <br /> will be backfilled and reclaimed as cropland. <br /> Mining in Phases 1, 2, 3, 4, 5 & 6 will be mined after the <br /> slurry walls are completed around them. Phases 1A, 4A, 4B, and <br /> 5A will be dewatered during mining so they can be mined dry. <br /> Dewatering will continue until mining ends in each of the <br /> backfill phases . <br /> The area being permitted and much of the surrounding areas <br /> has historically been used as cropland (irrigated and <br /> non-irrigated) , and vacant land. This site lies near the South <br /> Platte River, so it contains an alluvial gravel deposit in the <br /> western area, which extends into a large terrace of gravel in the <br /> eastern area. <br /> CURRENT CONDITIONS <br /> Large portions of the lands to be permitted are currently <br /> operated as irrigated farm land, by Cannon Land Company. There <br /> are two operation areas separated by HWY 85 and the UPRR tracks <br /> that run north to south. The area between the east and west <br /> L.G. Everist, Inc.
