6.4.5 Exhibit E <br /> Reclamation Plan <br /> Post-mining land use will be rangeland that will blend with the successful <br /> reclamation of the Flintlock Mine to the north. The post-mining land use will increase <br /> the open space area owned by Jefferson County to the east. The rangeland <br /> vegetation will enable a cattle lease opportunity for the CO State Land Board, the <br /> property owner. <br /> Topsoil will be salvaged and stockpiled along the east edge of the mine area. <br /> Topsoil thickness increases as one progressed east across the mine area. Whereas it <br /> is very thin near the toe of the vertical face, topsoil may be present to a depth of of <br /> eight inches along the east side of the proposed mine area. All topsoil, regardless of <br /> depth will be salvaged prior to mining. This will insure that sufficient topsoil will be <br /> available for reclamation; replacing to a depth of four to six inches. Stockpiled <br /> topsoil will be appropriately posted and segregated for use in reclamation if it is not <br /> immediately placed on backfilled and graded slopes. In the event the topsoil cannot <br /> be used within one year, the stockpiles will be broadcast seeded with a temporary <br /> seed mix or chemically stabilized. <br /> Reclamation will occur contemporaneously with mining once a linear length <br /> of approximately 300 feet is mined to the final 6050 feet elevation. At the end of <br /> mining, all reclamation will be completed within two years. Reclamation will include <br /> backfilling and plugging the inactive underground mine adits with interburden. As <br /> interburden and fines are produced during mining, the material will be placed at the <br /> toe of the hogback at a 3H:1V slope. Non-clay fines will be placed on the slope, and <br /> contoured with a bulldozer. Four to six inches of topsoil will be placed on the <br /> reconstructed slopes in this same contemporaneous fashion, reducing the need for <br /> stockpiles. This will also reduce degradation of the topsoil. <br /> The reclamation slope and vegetation will blend with the Flintlock Mine to the <br /> north to develop a consistent vista for the Jefferson County residents and passersby <br /> on the highway. Based on interburden production projections, approximately 25% of <br /> mined material will be interburden or reject material. Interburden is currently <br /> stockpiled on the north end of the mine disturbance. The existing stockpiled <br /> interburden will be used to build the stockpile and processing pad. As mining <br /> progresses the proposed 300 linear feet to a depth of 6050 ft. elevation, the <br /> interburden will be placed at the toe of the vertical face at a 3H:1V slope. The <br /> resulting slope will be approximately 15 vertical feet on the mine face and 45 <br /> horizontal feet eastward onto the mine floor. In the event interburden is in a greater <br /> quantity than anticipated, it will all be placed to construct the slope at the toe of the <br /> vertical face. Upon completion of mining, the material in the stockpile and <br /> processing pad will be transported to the south end, the final mine area, and used to <br /> continue the slope, ultimately blending with the topography to the east and south. <br /> The access road is owned by CO State Land Board. At the time of this <br /> application, it will be included in final reclamation. The road will be ripped using a <br /> loader fitted with a claw to loosen the compacted surface. The area will be graded to <br /> blend with surrounding contours. Topsoil will be placed to a depth of four to six <br /> inches and seeded. <br />
