EXHIBIT L <br />RECLAMATION COSTS (revised 6/25/2020) <br />The following information is provided to evaluate the amount <br />of bond needed when mining has reaches a point where L.G. <br />Everist, Inc. has Phases 1, 1A and 3 disturbed in some form or <br />another. The numbers presented for each Phase are based on what <br />is estimated to be disturbed at the time when mining has impacted <br />much of those areas. At this mine, it will not be necessary to <br />import fill material to complete reclamation in Phase 1A, as <br />discussed in the Mining Plan. The RECLAMATION ACTIVITIES table <br />below shows the various items needed to reclaim the initial 3 <br />phases once full production is taking place in that area. In <br />this scenario: <br />The first 4 tables are used in the Bond Cost Estimate but <br />each Phase represents the total cost to reclaim that Phase less <br />any activity that is not part of the Working Bond estimate for <br />this time period in the mine. The Floating Table has the costs <br />that will float from one Phase to the next as mining progresses. <br />The primary costs are the staging of the Bank Armoring in 1000 <br />foot segments with a minimum of 2350 cubic yards of concrete <br />rubble stockpiled within 500 feet of the placement area, the <br />stripped area in front of the working face, yearly weed control <br />and final grading of a 2600 foot long working face using a <br />cut/fill method (5.65 cy/lft). No dewatering cost is included <br />since we presume that the liner in Phase 1 will effectively seal <br />the mined area, so no dewatering is needed. <br />In Phase 1A, the slope will be mined 3h to 1v so no <br />underwater sloping will be needed and this Phase can be <br />backfilled, without pumping the water, to a point 2 ft above the <br />average ground water table. No ground water will be exposed in <br />Phase 3 while it is being used as the plant site area, so no <br />slurry wall will be installed until mining is planned for that <br />area. <br />Phase 1 is the active mining area. The cost to reclaim <br />would include all items shown in the Table for that Phase, less <br />the total armoring. As mining progresses, the items in the <br />Floating Costs table come into play. There are 30 acres stripped <br />in front of the working face that is 2600 ft long (5.65 yds/lft) <br />cut/fill sloping). <br />All other slopes will be finished and armoring installed as <br />L.G.
