EXHIBIT D <br />RECLAMATION PLAN <br />All mining activity will be located on privately owned land. Colorado Mining and Exploration, <br />LLC, will work closely with the Colorado Mined Land Reclamation Board to ensure that when <br />mining is complete all reclamation is completed in a timely and responsible manner. It is <br />Colorado Mining and Exploration's intent, wherever possible, to restore disturbed areas at <br />Crystal Hill to their original levels of natural productivity when mining operations have ceased. <br />Because potentially valuable mineral content will remain upon termination of mining, and <br />because the economics of potential future recovery dictate economic benefits from leaving <br />such deposits uncovered and near the surface of the earth, the open pit will remain. The <br />historical pit walls were engineered and constructed so as to minimize environmental <br />degradation. This is supported by the minimal amount of rock fall from the pit walls since the <br />open pit was last mined in the 1980's. <br />The open pit will retain the slope of the historic open pit. The slope angle is based on a slope <br />stability study conducted by John F. Abel, Jr., Mining Engineer, for the previous operator and <br />approved by the Colorado Department of Natural Resources. This study and supporting <br />documentation is attached in the Geotechnical Stability Exhibit. <br />Coarseness of mine waste and the lack of existing topsoil make it impracticable to topsoil the <br />mine waste dumps. However, the waste dump is planned to have ultimate contours that will <br />resemble natural deposits, and thus approximate natural appearing topography as well as <br />provide a viable ecologic regimen. This will include, but not limited to, grading so that the <br />material is stable and does not exceed the angle of repose, and construction of water bars to <br />prevent surface water runoff. <br />In the open pit, the base will be graded to produce a roughly flat surface and any unstable <br />lower benches will be stabilized. No soil exists in the historic open pit where mining will take <br />place, or on the existing waste dump that will be used for waste rock storage. <br />Review of these reclamation plans will be undertaken prior to termination of mining, and <br />modifications may be made where desirable. Such review will be done in full cooperation with <br />the Colorado Division of Reclamation, Mining and Safety. <br />Reclamation efforts will be directed toward restoration to a near natural state for as much land <br />as practicable. Where complete restoration proves impracticable, efforts will be directed <br />toward maximum mitigation of environmental hazards and degradation effects. <br />Once reclamation has been completed, habitat productivity should return to its pre- mining <br />levels, allowing a full restoration of wildlife values. The walls of the open pit will remain and <br />will probably inadvertently provide additional habitat for a few native animal species, especially <br />raptors. <br />
