RECEIVED <br />OCT 2 3 2002 <br />Division of Minerals and Geology <br />MINING PLAN IXHIBIT C <br />The Mining Plan for the Cucharas Pit is as follows (Please also see map): <br />a. The estimated starting date is November 1, 2002. The life of this mine will be <br />over 5 years. <br />b. Re soiling will not begin until mining is complete on the entire area because of <br />the limited room available for stockpiling and processing. All available topsoil will <br />be salvaged and stockpiled on the affected lands. We estimate the average <br />depth of the replaced topsoil will be 6". <br />The overburden (subsoil) will also be stockpiled on the proposed mining area. <br />See Reference Map: Exhibit E <br />Characteristics of the flora and fauna consist of rabbit bush, blue grams grass, <br />sand dropseed, needle and thread, prickly pear cactus, and yucca. <br />Characteristics of the undisturbed soils consist of a top 6"-12" layer of light <br />brownish gray sandy loam (topsoil). The substratum to a depth of 6" to 12" or <br />more is sandy loam. Pit run aggregate 6 to 7 feet thick is below the sandy loam <br />overburden. A seam of clay (thickness unknown) is below the gravel deposit. <br />Permeability of the soils is moderately rapid and effective rooting depth is 60 <br />inches or more. <br />The pit area will be basically the same type land and vegetation surrounding it. <br />The surrounding properties are rangeland. <br />c. The Mining Plan Map, will show in more detail the topography and the gravel <br />deposits. However, the nature of this deposit is a very gravelly sand material <br />used for construction aggregates, such as road base, and structural fill materials <br />as the main products. The overburden is about 1 ft. in depth, and the gravel <br />deposit is a mining of 6 ft. deep. Overburden will either be used in the product <br />mix or used for backfilling the pit. There are no secondary commodities to be <br />mined or extracted on this site. <br />d. The substratum to a depth of 6" to 12" or more will be mined for our primary <br />commodity being road base. However, mining will not be commenced within <br />two (2) feet of the water table. <br />
