<br />EXHIBIT C -paragraph 9 (continued) <br />The water consumed in the ore milling process wilt mainly resul~ <br />from water entrapped in the gravity and flotation concentrate: <br />and in the unconsolidated tailings. Because of the altitude anc <br />limited size of the tailings pond, only a relatively small amoun' <br />of water is expected to be lost due to evaporation. Recyclini <br />the mill water will reduce the amount of fresh water needed ii <br />the milling process, and decrease the quantity of water pumper <br />from Left Hand Creek. <br />Because of the hillside location selected for the tailing <br />impoundment structure, water runoff inflow will not b <br />substantial. A drainage diversion ditch will be excavated above <br />the tailings pond to intercept surface water runoff and convey it <br />away from the tailings impoundment area. <br />A seepage collection ditch will also be excavated around the <br />downstream perimeter of the tailings embankment dam. Tha water <br />that collects in this ditch will be conveyed by a pipeline to the <br />Hazel A. edit for underground storage and will be recycled <br />through the milling facility. <br />
