<br />Natural of the Deposit <br />The material to be mined consists of a clay body located within what is <br />described by G.B. Richardson (1915, Description o/ the Castle Rock <br />Quadrangle, Colorado, U.S.G.S Atlas Folio No. 198) as the upper part of the <br />Dawson Arkose, a formation exposed over much of the eastern half of the county. The <br />rock units underlying the area to be mined consist of variegated arkosic conglomerate, <br />sandstone and shale that is interbedded with andesitic sandstone. Clay lenses occur <br />throughout. The clay type is ared-burning variety and will be used for the manufacture <br />of brick at the company's plant located at Castle Rock. The material lies over other <br />sedimentary units. <br />Mining Plan <br />It is planned that operations will begin on the northeast side of the site and work <br />toward the south and west. The operation is expected to be dry. Test borings drilled to <br />a depth of 50 feet below the ground surface in the area to be mined encountered no <br />ground water. <br />The clay will first be ripped with a dozer and either pushed directly into a <br />stockpile or loaded into a scraper and transported to the stockpile. The pit will be <br />mined to depths ranging from about 27 to 45 feet, maximum. Product stockpiles (refer <br />to the Exhibit C map for a typical location) will then be depleted as necessary. Front- <br />end loaders will load the clay from stockpiles into haul trucks for transport to the plant <br />in Caste Rock. <br />It is anticipated that the site will be mined less than one hundred eighty (180) <br />days per year. <br />Processing <br />No clay processing will occur on site. <br />-5- <br />
