EXHIBIT B SITE DESCRIPTION <br /> 1. Location and General Land Use Information <br /> The site is located on a dry, elevated terrace north of State Highway 141,approximately 1.25 <br /> miles northwest of the Naturita City Center. The site is composed of and surrounded by dry <br /> rangeland and has been historically used for cattle grazing. The San Miguel River is <br /> approximately 0.5 miles southwest of the active mining area. The parcel landowner will also be <br /> the mine operator—Weimer Ranches, LLLP. <br /> 2. Site Geology <br /> Site geology consists of 0-8 inches of topsoil over Quaternary aged alluvium and terrace gravels <br /> underlain by Mancos Shale, Dakota Sandstone,and the Burro Canyon Formation. Williams <br /> (1964),describes the Quaternary deposits as follows: <br /> Alluvium and aeolian deposits, undifferentiated;mostly wind-deposited silt and sand on mesa <br /> tops, benches, and in broad valleys, reworked in part by water. <br /> The Mancos Shale in the vicinity of the Weimer Ranches#4 Mine is a fissile marine shale with <br /> thin sandstone beds. The Dakota Sandstone is a quartzitic fluvial sandstone and conglomerate <br /> sandstone. The Burro Canyon Formation is a quartzitic fluvial sandstone and conglomerate <br /> sandstone interbedded with green and purplish lacustrine siltstone, shale,and mudstone'. <br /> Mining will occur to a depth of—15 feet below the present surface. Variable overburden depth of <br /> 0 to 30 inches is found throughout the site. Topsoil and overburden depths at the Weimer No.2 <br /> Pit, approximately 500 feet to the east,were highly variable and were combined with landowner <br /> experience to determine topsoil and overburden replacement depths for the Weimer Ranches#4 <br /> Pit. There are no hazardous or acid forming materials expected to be encountered during <br /> excavation. See the Natural Resources Conservation Service(MRCS) soil report in Appendix 1 <br /> for more details on surface composition. <br /> ' Williams,P.L.(1964).Geology,structure, and uranium deposits of the Moab quadrangle, Colorado and <br /> Utah(No.360). <br /> Weimer Ranches #4 C-g I k*i std AS—a—N A A <br /> June 2021 B-1 <br />
