Appendix 5 -1 Reclamation Cost Estimate <br />Task 3 Cap Monitoring Wells <br />a) 2 wells each at 100ft well @ 4in dia. Approx 2.5 yd3. <br />b) Use -1 inch aggregate to fill well. Delivered aggregate cost is $35 /ton. <br />c) Use 90 -lb sacks concrete, hand mix to fill last 2 ft of wells. <br />Equipment Rates <br />Size <br />Labor <br />0 &M' <br />Op.

Dry material total 35t coarse ore bin, 100t fine ore bin =135t total material. <br />b) Operating costs based on UMC's Technical- Economic Model at 75t/d (3.75t/h @ 20hr /day) <br />c) All material and water in ball mill, conditioning tank, float cells and thickeners will be pumped out at same cost as dry material. <br />Material will be run through ball mill, then routed through float cells and to tailings thickener before reporting to TSF. <br />d) Lime will be added at ball mill to neutralize material. Metallurgical testwork on Cross Mine ore indicates 3.4kg of lime [Ca(OH)21 is required to bring <br />pH to 9.0. For purpose of this estimate, assume 2X this amount will be required. 6.8kg /tonne = 13.6lb /st = 0.007st lime per st -ore. Given 135 st <br />of ore must be treated, then: 0.007st- lime /st -ore x 135st -ore = 0.945st- lime is required. Assume 1 st lime will be required. <br />d) Process water (see Figure 4 -11) 3,900gal will be pumped through float cells and concentrate and tailings thickener to TSF. Reagents in the system <br />will also be pumped out with the process water. This will dilute the reagents and flush out the process system. Reagent amount in the system is minir <br />and will have di minimus affect on tailings chemistry in the TSF. <br />e) Fresh water (see Figure 4 -11) 10,600gal will be drained into sewer system via gravity. <br />No. <br />Task Description <br />Qty Unit <br />Hours Rate <br />$/ton <br />Cost <br />$ <br />Notes <br />1 <br />Crush Coarse Ore <br />35 tons <br />$4.11 <br />$144 <br />Based on UMC Technical Model <br />2 <br />Grind Coarse Ore and Fine Ore <br />135 tons <br />$2.62 <br />$354 <br />$4.72 basis without recirculating load factor, t.s <br />3 <br />Neutralize material with Lime <br />1 ton <br />$400.00 <br />$400 <br />$400/st- delivered price. <br />4 <br />Flush System with process water <br />135 tons <br />$0.25 <br />$34 <br />Pumping cost. <br />5 <br />Labor (2 personnel) <br />- - <br />36.0 $50.00 <br />$1,800 <br />2 personnel each @ $25 /hr <br />6 <br />Task 5: Process Remaining RoM <br />36.0 <br />$2,732 <br />RECLAMATION COST ESTIMATE <br />Union Milling Company, LLC 3 of 6 <br />Mill ReclamationCost 005nm -a <br />
