EXHIBIT A - Leaat Description The pit area is approximately 9.9 acres in the E 1/2 of Section 32 and the W 1/2 of Section 33, all in T2N, R44W of the 6th P.M., Yuma County, Colorado. Delineator boundary posts will be set to mazk the pit areas as shown on the map. EXHIBIT B -Site Description a) Ve eg tation - Native grasses and sagebrush currently cover the pit area. The azea is sparsely vegetated and has to be closely managed when grazed. Overgrazing will cause erosion and loss of the grass population. Soil Information - The Natural Resource Conservation Service soil maps show two soils within the pit area. They are both Valent Sand. The only difference between the two soil profiles is the slopes where they exist The primary slopes within the pit area range from 1 to 15 percent. The soils consist of deep, excessively drained soils on sand hills. Permeability is typically very rapid. Surface runoff is slow. Water erosion is a moderate hazazd and soil blowing is a severe hazazd. The soil is an excellent source of good sand that is the material to be mined at this site. b) Permanent man-made structures There are two electric power poles in the pit azea. No other permanent man- made structures lie within 200 feet of the pit boundaries. c) Water resources The pit site lies north of the Chief Creek tributary to the Republican River. The normal water table below the site is about 25-30 feet below the surface. Excavation will stop prior to an encounter with the water table. The anticipated mining depth will be 20 feet. Thus, no water should affect mining efforts. Rainfall can cause the pit area to be unworkable for short periods, Since the Valent Sand is highly permeable, rainwater will quickly soak in and Leave the pit azea dry again. Rainfall in the azea averages about 16.7 inches per year. The site will generally not be impacted by water.
