Banks and Gesso, LLC <br />Exhibit D -Mining Plan <br />Overview <br />The St. Barbara Sand and Gravel Mine permit area is approximately 364 acres, of which <br />eventually 304 acres will be mined. A plant and product stockpile area of approximately <br />30 acres and a fresh water/settling pond area of approximately 18 acres will be placed in <br />the northwest area of the permit property. Both of these areas will be mined. The plant <br />area will contain product stockpiles, crushers, screens, conveyors, a wash plant, scale <br />house, office and associated outdoor storage and vehicle and equipment parking. <br />Sand and gravel products will be mined, processed and shipped at the rate of 300,000 - <br />500,000 tons per year. This rate of production will require mining about 5 to 7 acres <br />annually. This will be a dry mine, and dewatering will take place continuously over the <br />life of the mine. Topsoil, overburden, and sand and gravel will be excavated by front- <br />end loaders, dozers or scrapers, and will be transported to the plant site by truck, <br />conveyor, or front-end loaders. <br />The end land use of ibis property will be wildlife habitat with 2 ponds comprising 210 <br />acres and 94 acres of reseeded land at approximately the pre-mining grade. <br />Schedule and Seouence <br />Mining is scheduled to commence in summer of 2004 and continue for at least 25 years, <br />depending on market demand and economic conditions. <br />The initial stage of operations will include construction of the plant and associated <br />facilities in the plant area and construction of the freshwater/settling pond area. The <br />process water ponds will remain in the same area until mining and processing of the <br />remainder of the property ceases. <br />Mining will then begin east of the plant area and proceed east to the eastern permit <br />boundary setback. Once excavation reaches this setback, mining will move to the west <br />portion of the property and proceed east again, repeating this process until mining area <br />1 is exhausted (see Exhibit C-3 for mining sequence). <br />St. Barbara Sand and Gravel Mine 03028 <br />Trans Colorado Concrete g February 19, 2004 <br />
