LONDON MINE <br /> M-2023-015 <br /> Exhibit D—Rule 6.3.4 <br /> Reclamation Plan <br /> The post-mining land use of this site is Commercial/Industrial. Past disturbances included historic mining <br /> and processing, plus recent water quality activities. Under this permit activities will center around the <br /> moving and sorting of old mine waste, and the permanent disposal of sorted, non-mineralized waste. <br /> There was no previously-unaffected area within this permit; no native ground with soil to salvage, no <br /> vegetation to re-establish. The reclamation of this site concentrates on stabilizing these lands to <br /> minimize surface runoff and ground percolation of mineralized water,offsite sediment transport,and <br /> control of erosion. <br /> The onsite roads which pre-existed here were maintained during the mining stage and will remain as <br /> permanent features. The permanent onsite buildings were maintained and will remain onsite. <br /> All fuels,fluids,storage tanks and any contaminants will be removed from the site and disposed of in <br /> proper, licensed facilities as needed. All temporary structures will be removed from the site. Wooden <br /> waste materials will be legally burned or removed to a licensed landfill site as necessary. Any inert solid <br /> waste materials,such as concrete or stone will be broken as needed and buried onsite (though the <br /> operator may retain structurally sound pads onsite for future industrial use. Stockpiles of mineralized <br /> material will be removed; less-or non-mineralized (barren) materials will be placed in permanent <br /> disposal cells in stable configurations and locations. These areas are shown on the Reclamation Maps in <br /> Exhibit E. <br /> All mobile/earthmoving equipment and stationary equipment(including the sorting plant)will be <br /> removed from the site. <br /> Runoff and sediment control structures,whether pre-existing or constructed for this operation,will most <br /> likely remain permanently on the site, due to the overall degree of disturbance,the surface slopes,and <br /> the proximity to South Mosquito Creek. This is shown on the maps in Exhibit E. <br /> After all the waste rock in the South London Stockpile area has been moved to the sorter,the placement <br /> of the barren portion for permanent disposal will begin. The material will be carried by trucks and <br /> loaders to the area,and will be compacted as it is spread by dozer. No final slopes will be steeper than <br /> 30%. Erosion control wattles will be employed to catch sediment on the new slopes, probably midway <br /> down the slopes, but definitely at the toe of the slopes. <br /> After all the sorting has been carried out,the barren waste rock from the Central Extension and Sorting <br /> Plant area will be replaced on the upper and lower waste rock areas. It will be carried, spread and <br /> compacted as described above. New slopes will be 30%or less,and will contain sediment control <br /> structures as described above. <br />
