2.5 Exhibit E: Reclamation Plan <br /> The Dawson Gold Mine site will be reclaimed to wildlife habitat. After mining is complete and the mill is <br /> no longer in operation,final reclamation will begin. During reclamation,the mine portal and all mine <br /> openings are sealed,the mill is dismantled,the disturbed areas are stabilized and pre-mining conditions <br /> are re-established with contours reflecting elevation changes resulting from the construction of various <br /> pads, roads and the FTSF during the LOM. <br /> 2.5.1 Growth Medium Materials <br /> The soil type at the proposed mill site is Bronell gravelly sandy loam according to USDA NRCS web <br /> survey. Gravelly sandy loam may exist up to 16 inches deep. During development of the entire mill <br /> facility including FTSF, storage areas, laydown area etc,four to six inches of topsoil (growth medium)will <br /> be salvaged. The salvaged growth medium will be maintained in the topsoil stockpile located at the <br /> north end of the mill site. It is anticipated that approximately 24,000 yd3 will be stockpiled during site <br /> development. <br /> 2.5.2 Beneficial Use of Removed Trees <br /> Native vegetation on the mill site includes pinyon and juniper trees. During site development,the trees <br /> will be scrubbed and stockpiled. A tree removal contractor will be hired to make the scrubbed trees into <br /> firewood or mulch. The end product(s)will be made available to the community through the tree <br /> removal contractor. <br /> 2.5.3 Reclamation Procedure <br /> 2.5.3.1 Mill and Building Demolition and Removal <br /> All surface structures and mining equipment will be dismantled and removed from the site to <br /> other industrial sites to be reused. Mill components including ore sizing equipment will be <br /> transported off-site. Metal buildings will be dismantled and hauled off-site. Manufactured <br /> buildings will be transported off-site. <br /> During mill demolition, large equipment and structures that are not moved to other industrial <br /> sites will be cut to sizes that can be safely moved by salvage contractors to recycling yards. <br /> Concrete building foundations and concrete pads will be demolished using a loader and a <br /> bulldozer equipped with a ripper. Concrete debris from slabs and foundations will be broken to <br /> sufficient size to be used as backfill to seal the mine portal and ventilation shafts. <br /> 2.5.4 Mine Portal and Ventilation Raise Closing <br /> Once mining has been completed, equipment and materials will be brought to surface prior to <br /> closure.The portal access will then be backfilled with concrete debris from slabs and mill <br /> foundations, and rock fill to ensure the mine entrance and portal face is completely covered. <br /> The portal will be sealed with a concrete plug as described in the DRMS AMS handbook. Topsoil <br /> will be placed on the concrete plug and sloped for final reclamation. <br /> Once the main ventilation fan has been removed,the ventilation raise will be backfilled and <br /> sealed with a concrete plug.The placement of fill will be mounded above the raise opening to <br /> allow for possible settling or subsidence over time.The concrete plug will be capped with a <br /> topsoil cover for final reclamation. <br /> 31 <br />
