EXHIBIT B <br /> Site Description <br /> Numerous prospect pits, surface disturbances, and an inactive open pit dating from the 1980's <br /> already exist at Crystal Hill. In addition to the pre-existing open pit (approximately 7.2 acres), <br /> other previously disturbed areas include reclaimed waste dumps and heap leach pad <br /> (approximately 39.1 acres), and about two miles of access roads. <br /> The bottom of the historic open pit is at an elevation of approximately 9,000 feet, and is <br /> approximately 380 feet by 280 feet in area. The open pit has the form of a steep-sided, <br /> topographically closed, flat-floored amphitheater facing west and carved into the southwest <br /> side of Crystal Hill. The top of the open pit is approximately 600 feet by 600 feet. There are no <br /> pre-existing buildings at the mine site. The only pre-existing man-made features in the vicinity <br /> are a few livestock watering impoundments, fences to delineate grazing areas and a gate to <br /> block access to the open pit. <br /> Current land use in the area, not related to prospecting and mining exploration, appears to be <br /> limited to livestock grazing, seasonal hunting, mostly deer and elk, woodcutting, National Forest <br /> access, and rockhound activities. <br /> SOIL CHARACTERISTICS <br /> The proposed affected area has been previously disturbed by historic mining activity and is <br /> situated at an elevation of about 9,000 feet on a west-facing slope. The area of the historic <br /> Crystal Hill open pit has been denuded of soil and cover, and consists of rock outcrops. Historic <br /> waste dumps found outside of the open pit have been reclaimed by grading and seeding, and <br /> contain very little soil. <br /> As part of the previous operator's mine permit application, Impact Environmental Consultants, <br /> Ltd., a Denver-based research and service group, conducted a field survey to confirm the <br /> observations of a U.S. Soil Conservation Service report which included the proposed permit <br /> area. In November 1980, the U.S. Soil Conservation Service (SCS) made a site visit, and <br /> provided a written report on the soils of the area. <br /> The mapping units SCS described are complexes consisting of two or more soils series. The four <br /> mapping units identified by the SCS in the Crystal Hill area are the Jodero-Lolo complex, the <br /> Tolman Rock Outcrop complex, the Bushvalley-Tellura complex, and areas of Rock Outcrop. For <br /> the most part, these designations are coincident with hillslope gradients. <br /> The results of the SCS and Impact Environmental Consultants, Ltd. surveys were used to <br /> develop a soils map for the area, presented as Exhibit B - Soil Map. <br />
