MINING PLAN EXHIBIT D (CONT) EXHIBIT C -PRE- MINING MAP shows the outline of the mining area, the touching landowners, easements and ROWS, the 200 foot owner- ship, current topography, and hydrologic features of the prop- erty. Surrounding property uses includes, rangeland, forested areas and rural ranchetts. The closest house is approximately 2100 feet northwest of the mine. The site will be accessed using an existing road currently used to get to gas facilities and property north of the mine site. The gas companies maintain the road as needed to allow heavy equipment access and it will remain when reclamation ends. GEOLOGIC SETTING The affected lands are located on an east -west trending ridge that is a member of the Raton Formation with a 0 -36 foot thick intrusion or sill of basic igneous rock inserted between a dark -gray silt stone on the bottom and a conglomerate on the top. It is a gray to grayish -black Gabbro Porphyry found in sills, dikes and plugs throughout the vicinity. SOILS AND OVERBURDEN See the soils and vegetation information for the soils report prepared using the Natural Resources Conservation Service Web Soil Service for the soils on this site. The soil informa- tion prepared by this service is not site specific, it describes in general terms the nature of the soils found at this site. Soils on the proposed mine site tend to be fairly uniform even thought the topography varies. This site contains 2 types of soil according to the Soils Survey information; the Lorencito- Rombo- Sarcillo Complex, 25 -60% slopes - Map symbol LRT, This soil makes up approximately 3.7% of the soils on the site. It is a soil complex containing properties of each soil in the group. In general this soil is described as shallow, and well - drained varying in depth from 0 to 26 inches. Only the upper 0 to 4 inches would be suitable for topsoil. On this site this soil type occupies a small area on the very western side of the site. This area is fairly steep, stoney and is underlain by the rock that will be mined. Origins of the soil are alluvium and resid- uum derived from shale and silt stone, probably eroded from the material over the rock to be mined. The Lorencito - Sarcillo- Trujillo Complex, 3 -25% slopes - Map symbol LST. This soil makes up approximately 97.3% of the 4
