EXHIBIT E Reclamation Plan Design intent The Iverson property will be reclaimed as an unlined, open water pond surrounded by uplands. Native and adaptive plantings and ground covers will be used to restore and enhance all areas disturbed by mining activities. The most appropriate primary post-mining land use designation for the site is wildlife habitat given the fact that a majority of the property will be covered by the open water pond. However, this designation is for purposes of the DRMS application only and the property is not designated by any other agency as wildlife habitat. Therefore, following reclamation and release of the property by the DRMS, the land use of the property could be changed by the land owner according to the land use regulations of Weld County. This Iverson Mine reclamation plan was developed based on the following considerations: • A thorough evaluation of the environmental resources and existing conditions on and adjacent to the property, particularly the Cache la Poudre River riparian corridor along the west, north and east sides of the property; • The context of the property relative to existing and planned land uses in the area; • The volume, depth and configuration of the mineral resource; • The landowners' plans for the property; and • The rules and policies of the Colorado Division of Minerals and Geology and other applicable local, State and Federal agencies. • The open water pond, which will be created upon reclamation of the Iverson property, may provide some wildlife habitat due to its proximity to the river corridor. Post-Mining Land Use Following the mining of the Iverson property, the land will be reclaimed with an open water pond surrounded by upland. All areas reclaimed as upland will be re-vegetated with a native seed mix, as recommended by the Soil Conservation Service (recommended seed mixes below). This use is compatible with the surrounding land uses. Lafarge will concurrently reclaim mine walls where mining has been completed. Reclamation, including re-grading and seeding, will be completed within two to five years following the completion of mining or filling operations. The mining and reclamation will leave no high walls on the property. No acid forming or toxic materials will be used or encountered in the mining. There will be no auger holes, adits, or shafts left on the site. Topsoiling Topsoils in the proposed mine areas are Aquolls and Aquents, Ascalon loam, Dacono clay loam, Nunn loam, and Otero sandy loam. All suitable soil material will be salvaged for topsoil replacement. The topsoil will be segregated and stored separately from the overburden material as required by Rule 3.1.9(1). Upon reclamation of the site, all upland areas will be reclaimed with at least six inches of topsoil. Iverson Mine DRMS 112 Reclamation Permit Application Page El of E4
