Exhibit D- Mining Plan Of the 157.06± Acres of lands comprising the parcel boundary, 3.41± acres surrounding an existing residence and outbuildings are not included in the permit boundary, resulting in total permit area of 153.65± acres described as follows: 65.57± Acres of Planned Extraction - Tract A - 05-15± years. 40.69± Acres of Planned Extraction - Tract B - 10-20± years. 26.26± Acres of Planned Extraction - Tract C - 01-25± years. 132.52± Acres of Planned Extraction - TOTAL, Of the 132.52± acres of planned extraction, the remaining 21.13± acres of the permit boundary comprise planned or existing permanent access roads, operational support use, or areas of minor to no disturbance. Lands not otherwise occupied will be later developed to the highest possible end-use, and will likely comprise a mixed use which may include other agricultural uses, as well as light residential, commercial, or industrial uses. As indicated in Exhibit E - Reclamation Plan; of the 132.52± acres of potential extraction, the resulting basin will function as a reservoir with a surface covering 105.44± acres of water, leaving a balance of 31.01± of affected land above the anticipated high water mark to be revegetated. Tracts A and B comprise the northern and central portions of the parcel. While found within the upper terrace of the flood plain of St. Vrain Creek, the FEMA designated flood plain does not reach the site location since a rail road bed to the northwest intercepts and prevents flood waters of St. Vrain Creek from reaching the location. Soil and overburden vary over the location to a depth of 4.0± feet. Actual soil variations, depths and descriptions, including potential volumes to be extracted, are detailed in Exhibit I & J: Soils and Vegetation Information, and are shown on Exhibit I & J: Soil and Vegetation Map. Aggregate extends from the overburden to a depth of 49± feet from the surface until it reaches the unconsolidated layer of Pierre Shale. Surface elevation for these tracts is established by survey at the existing water monitoring well identified in Tract A. Elevation at the surface is 4798.45± feet, with groundwater at 6.80± feet below the surface, or elevation 4791.65, as determined by a water level meter (March 2006). The upper terrace of the St. Wain flood plain of Tracts A and B meet the escarpment and uplands of Tract C which comprises the balance of the parcel to the south. This location is influenced by Aeolian deposits up to 4.5± feet in depth. The soil and overburden extends to an approximate depth of 25.0± feet.
