Page 5 <br /> 6.4.4 EXHIBIT D — Extraction Plan <br /> 5.11± feet from the surface, we determined the Static Water Level using the <br /> upper limit of 5.0± feet. The Cyan colored contour shown on Exhibit G: Water <br /> Information Map represents the Static Groundwater Elevation at 4675' at <br /> North-West Field, and 4673' at Central Field. Since completed reservoirs will <br /> be lined to meet State of Colorado Water Resources specifications and <br /> requirements, and since lined basins will ultimately equalize with the <br /> surrounding groundwater elevations, the Static Water Levels shown should <br /> reasonably reflect those of the both the lined or unlined state; and represent <br /> a proper reflection of the optimal surface area of the water over the finished <br /> basins. Raptor Materials, LLC has sufficient water to meet the circumstances <br /> and obligations of both the lined and unlined states; and as reflected under <br /> Exhibit G: Water Resources Information; until and unless the reservoirs have <br /> an approved liner, the Operator will dedicate sufficient waters to secure the <br /> reclamation of the resulting basins in the unlined state. <br /> Planned Field Activities: The 409.23± acre parcel boundary forms the permit <br /> boundary, as reflected on exhibit maps. All lands under its direct control <br /> within the 409.23± acre permit area, are affected lands under C.R.S. 34-32.5- <br /> 103(1), respective of this permit application. As a result, any changes required <br /> in the nature of planned extraction or reclamation will be made only through <br /> the Colorado Office of Mined Land Reclamation (OMLR), by Technical Revision <br /> only. If lands are needed beyond the designated permit boundary, those lands <br /> will be secured for the active OMLR permit by Amendment. <br /> Within the permit boundary, there are two* (2) identifiable areas designated <br /> for primary extraction, the description of which will help to explain the nature <br /> of planned extraction and reclamation. The Primary Areas of Extraction are as <br /> f ollows: <br /> 180.76± Acres = Primary Extraction (***) Central Field: 20-30± years (2023- `53) ** <br /> 53.30± Acres = Primary Extraction North-West Field: 5-10± years (2048- `58) ** <br /> 234.06± Acres = Total Primary Extraction * <br /> 175.17± Acres = Affected Lands beyond planned extraction limits <br /> 409.23± TOTAL <br /> (*) NOTE: The third area of secondary extraction is limited to approx. 5.60±Acres for a <br /> Plant Processing/Stockpile Area Pond, as further indicated, below; and is not included in <br /> this total. <br /> (**) NOTE: Final reclamation will add up to five (5.0±) years to the anticipated Life of the <br /> Mine, subsequent to completion of extraction and removal of all marketable <br /> materials. Life of Extraction is an approximation, and could lengthen or shorten the <br /> overall life of the mine depending upon market conditions. <br /> (***) NOTE: Of the 180.76± Acres of Primary Extraction, 4.09± Acres comprise an <br /> existing Farm Yard & Structures with residence.
