Long Term Reclamation Activities <br />As mine operations progress to the north over time, the lower pit azea and final outslope <br />of the lower waste rockpile will be scheduled for re-vegetation. Topsoil from the lower <br />staging azea not consumed during eazlier reclamation activities described above will be <br />used for covering the final slope of the lower rockpile which will have grown in size to <br />approximately 6 acres. The final grade of the rockpile will be no greater than 3:1 slope <br />and no less than 6" topsoil will be applied to the final graded slope. Contour furrowing <br />techniques will be used on final graded slopes to minimise erosion and gullying until <br />vegetation is established. Slope breaks no farther apart than 100' will be constructed to <br />minimise sheet erosion. Slope breaks will be constructed with bulldozer grading to result <br />is a contour ditch and associated trail no wider than 10'-12' to allow for reclamation <br />equipment access such as pick-up truck and mulching equipment. The slope and berms <br />will be broadcast seeded at a rate of 20#/acre and will be mulched with clean straw at a <br />rate to less than 2000#.acre. The lower staging area will be final graded to slopes not <br />greater than 3:1 and topsoil applied no less than 6" prior to seeding mulching as <br />described above. <br />Final highwall rock faces will remain along the western side of the mine pit after mining. <br />In the lower benches of the pit azea (where mazble outcrop is left in place), rock faces no <br />steeper than 85°, or the angle of bedding plane approaching 90°, will be left with <br />unbroken runs of rock face not to exceed 40'. Waste rock from mining development in <br />the northern portions of the pit will be used to backfill the lowest two benches remaining <br />in the southern portions of the mining zone. Along the upper horizontal runs of the mine <br />benches, a containment berm no less than 4' high will be left 6'- 8' from the vertical face <br />with a total horizontal bench width of no less than 20'. The flat tops of the benches will <br />be capped with a topsoil depth of 1'. The flat benches will be graded 1 % to the west <br />(highwall direction) to minimize surface flow over the face. The upper benches of the <br />highwall system will be capped likewise with 1' of topsoil prior to seeding and mulching. <br />The final outslope angle of upper benches, cut in quartzite bedrock, will be determined <br />based on [he outcome of the quartzite weathering characteristics and rock hazdness. The <br />quartzite bedrock face will be no steeper than 70° but may be left as low 45°. <br />Pit floors and waste rockpiles will be graded to a final slope of no steeper than 3:1 prior to <br />capping with topsoil material bulldozed from the upper mine beaches or sourced from <br />topsoil stockpiles located immediately east of the waste rockpiles constructed east of the <br />hangingwall of the mazble outcrop. Topsoil used for capping of pit floors and fmat <br />graded slopes of the waste rock piles will be applied at no less than 6" depth prior to <br />seeding and mulching operations. Contour furrowing techniques will be employed to <br />m;n;m;~e vertical rifling or gullying on all slopes. Slope breaks no less than 100' apart <br />will be constructed via bulldozer grading to result in narrow roadway for reclamation <br />equipment access (10'-12') and ditch along the contour. <br />14 <br />
