Banks and Gesso, LLC <br />Exhibit D -Mining Plan ~~~~~` ~~~ <br />OCT 0 2 2006 <br />IntrOdUCtiOn Division of Reclamation, <br />Mining and Safety <br />The proposed Sundance Resource site is a sand and gravel extraction operation located <br />approximately five (5) miles south of Fountain in EI Paso County, Colorado. Lafarge has <br />a Gravel Property Lease with the property owners, Sundance Investments, for the <br />subject property. Total mineable acreage is estimated at 437 acres. There will be <br />additional acreage affected by stockpiles of topsoil and overburden placed around the <br />periphery of the Phase I pit to visually screen aboveground plant operations. The total <br />proposed affected area is 479 acres. <br />Lafarge plans to extract sand and gravel from the property, process it on site and sell it <br />as is or use it to make concrete and asphalt. Blasting will not be necessary to recover <br />the reserves onsite. Reserve estimates based on test pits and borehole samples show <br />30 million tons of gravel contained within the proposed disturbance boundary. The <br />Sundance Resources operation will process up to 2.0 million tons of aggregate per year <br />and mine approximately 25 acres per year. Lafarge estimates a mine life of 15+ years, <br />although market conditions will determine the life of the mine. Lafarge intends to use the <br />Sundance site as a replacement for the current Lafarge Fountain Pit. <br />Initial Operations <br />Initial operations will consist of preparation of the processing area and the freshwater <br />(stormwater management and dewatering) pond. The freshwater pond will first be <br />stripped of topsoil and overburden (to be temporarily stockpiled at the western boundary <br />along with topsoil and overburden from the processing area). Aggregates beneath the <br />freshwater pond will be recovered and the footprint will then be backfilled with <br />overburden to achieve functional grading for the basin. Processing will be established <br />on an aggregate base by stripping topsoil and overburden and, if necessary, backfilling <br />with recovered aggregates to establish grading for drainage. <br />Mining Methods <br />Mining operations will include topsoil and overburden stripping. As areas are cleared <br />and stripped, previously mined areas will receive backfill material to establish the <br />permanent design side slopes and/or fill to near-existing grades (see below and Exhibits <br />Sundance Sand and Gravel Resource 06015 <br />Lafarge West, Inc. 6 September 2006 <br />
