<br />Spill containment in the mill is controlled by a <br />collection sump built into the concrete floor at the lower <br />end of the mill. <br />Before tailings are discharged into the tailings <br />disposal area, the slurry will be tabled after flotation to <br />remove pyrite. Pyrite, like the magnetite, will be marketed <br />as a by-product. <br />Tailings will be maintained at an alkaline state <br />throughout the flotation process and will be discharged into <br />the tailings disposal area at or about a pH of 7.5 to 9.0. <br />Mineral concentrates will be filtered and sold to <br />smelters or other ore buyers. <br />The mill is designed with a nominal capacity of 125 <br />tons per day. It is our intent to furnish most of the mill <br />feed from the Hopemore Shaft, but we plan to utilize any <br />excess mill capacity_to treat odes from other mining <br />companies on a custom fee milling basis. In addition to <br />possible additional revenue, we believe this service will <br />benefit the mining industry in Colorado. However, only ores <br />which are amenable to our milling process, and which will <br />not create any problems economically, physically or <br />environmentally, will be considered. <br />It is our intent to begin milling about April 30, 1990, <br />with an estimated duration of life of approximately 12 <br />years. <br />
