• Soil erosion resulting from the operation has been stabilized; and • A vegetative cover at least equal to that present prior to the disturbance has been established. Reclamation Costs The CM -25 Mine permit consists of two major parcels - the mine waste area and the proposed venthole areas. Listed below are the significant parts of the reclamation efforts required at each parcel, followed by the calculations for reclamation costs. Mine Waste and Portal Area Cost Remove office trailer $400 Plug portals $400 Re- contouring the mine waste dump $1,160 Spreading soil material $2,520 Pocking waste dump $1,250 Seeding $1,129 Plug ventholes $3,580 Total $10,439 The cost to remove the office trailer is based on two men taking apart the office trailer in 4 hours and hauling it offsite. The estimated cost is $400. The cost to remove the concrete for the shop building pad and put it inside the portal is included in the cost to plug the portal. The northern portal will be closed by replacing the bat gate, which is currently installed in the portal, back in place. The bat gate will be removed from the portal in one salvageable piece when mining operations resume; therefore, this gate should readily re- attach to the frame at the portal for final reclamation. The southern portal currently has a locked bat gate on it which will be maintained as such during mining operations. There should be no cost to reclaim this. Cost = $400 to re- attach the bat gate to the frame at the portal The cost to re- contour the mine waste dump is based on using a D -6 dozer, or equivalent, to push the mine waste material to a 2H:1 V final slope. The mine waste dump will consist of an upper tier, located just outside the portal, and a lower tier for the ore stockpile and haul truck access. It is estimated to take approximately 8 hours to re- contour the waste dump to a 2:1 slope. Cost = 1 dozer x $145 /hr x 8 hr = $1160 D -4
