EXHIBIT D Mining Plan General The Parsons Mine property is located in the East %2 of the Southeast '/ of Section 25, Township 6 North, Range 67 West of the 6th PM; in the West/2 of the Southwest'/ of Section 30, Township 6 North, Range 66 West of the 6th PM; in the Northeast '/ of Section 36, Township 6 North, Range 67 West of the 6th PM; and in a portion of the Northwest'/ of Section 31, Township 6 North, Range 66 West, of the 6th PM. The site is directly south of Weld County Road 64%2 and Weld County Road 25 bisects the property. The property contains a significant commercial deposit of sand and gravel located near the Cache La Poudre River. The permit boundary will encompass approximately 381 acres, with mining activities anticipated to disturb approximately 189 acres of the site. The remaining unmined acres will be used for overburden and topsoil stockpiles, offsets from existing structures, property lines and waterways, and internal road and conveyor access. Agricultural uses surround the property with the exception of some reclaimed gravel mining ponds that are southeast of the property. The site has been drilled during sampling episodes from March of 2002 to April of 2007, and testing has been performed to verify the sand and gravel deposits are commercially marketable. Based on test results, it is estimated that the overburden will amount to approximately 1,865,000 cubic yards. Overburden exists to an average depth of approximately 7 feet over the entire site. All overburden needed for the construction of the final reclamation slopes will remain on-site. The average depth of sand and gravel is 13 feet across the site and mining at the site is intended to progress down to bedrock. The groundwater level lies approximately 5 to 15 feet below natural ground level, on average. The deposit is therefore classified as a wet alluvial deposit. However, mining operations will be carried out following dewatering. The site is owned by Lafarge West Inc.; Livingston Leigh Livestock of Weld County, LLC; and Sally A. Parsons. Lafarge has a lease to mine the Livingston Leigh Livestock of Weld County, LLC property and both a lease to mine and an option to purchase Sally A. Parson's property. The site will be mined in five phases. These phases are neither representative of the maximum area of disturbance nor do they limit disturbance to a particular phase. The mineral rights in the portions of the site that fall in Section 36 are owned by the Colorado State Board of Land Commissioners. This affects portions of the land owned Sally A. Parsons and Livingston Leigh Livestock of Weld County, LLC. Methods of Mining The typical mining procedure for all phases will be as follows.
