NIINING PLAN <br />1. General Minine Plan <br />EXHIBIT D <br />The property boundary has been surveyed on site and the permit area will be surveyed prior to <br />any site disturbance. Map C-2 shows the mining plan. <br />The gravel zone is approximately 40 feet thick in a alluvial deposit and is overlain by soil and <br />overburden ranging from 4 to 15 feet. In general, the area will be mined by first excavating <br />soil/overburden with front end loaders which will be used to backfill the slopes of mined Phases <br />to a 3H:1 V slope as well as building peninsulas as shown on Map F. Since the thickness of the <br />overburden and gravel is so great across the Anderson property, the feasibility of creating the <br />peninsulas exists. Note that the shapes of the peninsulas shown on Map F are approximate. <br />Exhibit E Reclamation Plan addresses the construction of these peninsulas more specifically. <br />The raw gravel material will then be loaded into a crusher/screen plant where various sizes of <br />product will be made and placed in separate stockpiles. Dozers may also be used to move <br />topsoil/overburden or gravel. Mining activities are expected to occur approximately 3 to 5 <br />months per yeaz, while the processing operations including screening/crushing and washing will <br />occur yeaz round. Mining will proceed in Phases from the northwest corner of the gravel deposit <br />east through Phases 1 through 3, as shown on Map C-2. Upon completion of the mining of Phase <br />3, mining will proceed immediately to the south in Phase 4 and will then mine west through <br />Phase 6. At the completion of Phase 6, mining will proceed south to Phase 7 and Phases 7 <br />through 9 and then 10 through 12 will be mined in the same fashion as Phases 1 through 3. The <br />mining of the deposit will occur to the limits shown on Map C-2 and will be mined to a slope no <br />steeper than O.SH:1 V in order to maximize gravel recovery. <br />United Companies mines using a O.SH:1 V to neaz vertical slope on active mining faces. <br />Highwall mining will progress to an offset of the crest line which marks the mid-slope of the <br />final mining 2H:1 V slope. Both boundaries will be staked prior to mining in the area. This <br />offset serves two purposes. First, the volume of material left in the highwall will allow the crest <br />Anderson Pit February OS D-1 <br />
