EXHIBIT D MINING PLAN (CONT) <br /> location, the velocity of the river must have slowed sufficiently <br /> to have dropped boulders and most large cobble before it reached <br /> this point . <br /> This type of material is typically found from south of <br /> Denver to the Colorado state line along the South Platte River . <br /> The thickness of the mineral deposit varies from 8 to 52+ <br /> feet and the average depth on this mine is approximately 40 feet <br /> deep. This site has a zero to 10 inch layer of topsoil, <br /> consisting of loam and zero to 36 inches of a clay loam to sandy <br /> clay loam overburden that overlays the gravel . This alluvium is <br /> a well sorted coarse gravel, sand and silt, predominantly <br /> granitic and quartzite material with minor amounts of gneiss, <br /> schist and sandstone. The bedrock under the surface gravel is <br /> grey to grey black shale that is impervious . <br /> SOILS AND OVERBURDEN <br /> The SOILS MAP IN EXHIBIT I, shows the soil types as delineated by <br /> the National Resource Conservation Service (NRCS) and obtained <br /> from their website . The information contained in EXHIBITI/Jwill <br /> provide background levels for the site as reclamation begins on <br /> the entire area. The depths of the topsoil and overburden, shown <br /> in the following table were obtained from drill logs provided by <br /> the Cannon Land Company. <br /> There are eleven (11) types of soils found on the site . <br /> These soils are typically found throughout Weld County. They have <br /> no unusual qualities . The eleven types of natural soils on the <br /> site as determined by the Natural Resource Conservation Service <br /> and shown in the report are designated as map Units 1, 2, 3, 10, <br /> 16, 21, 22, 38, 42, 52, and 76. Soil units 38 and 76 are very <br /> small areas on the edges of the mine that will not be mined. See <br /> the soils map in the NRCS report for how the soils are <br /> distributed on the permit area. The NRCS report contains <br /> detailed information including the soils description, and <br /> chemical, physical, and engineering qualities, which can be found <br /> in EXHIBIT I-SOILS. <br /> The Vegetation inventory applies to only the non farmed area <br /> in each soil type and is provided as background for when the <br /> perimeters of the lakes and backfilled areas are revegetated. <br /> Typically, at this time, the irrigated areas are used to grow <br /> various crops, such as corn, wheat, barley, sorghum or <br /> sunflowers . <br /> L.G.
