<br />ITEM #11 <br />We do not believe a larger than 4.6 acre area for tailings <br />disposal is necessary. <br />Current known ore at the mine is estimated at 12 years <br />operating reserve. Our tailings volume calculations <br />indicate an average maximum depth of tailings which could be <br />accumulated in the 4.0 net acre disposal area would be a <br />depth of 2.35 ft. per year if the mill ran at capacity 250 <br />days per year. <br />Once in operation, we estimate the capacity tonnage to be <br />run through the mill 838 of the time. This 83$ figure is <br />the basis for determining that our tailings disposal area <br />will adequately hold our estimated 12-year mining reserves. <br />Our calculations indicate the 4.6 acre area for tailings <br />disposal is adequate. These calculations are based on the <br />following data: <br />1. A net area of 4.0 acres for tailings disposal after <br />deducting .6 acre for constructed clay-soil embankment. <br />2. Mill heads tonnage of 31,250 tons per year. <br />3. Tailings disposal tonnage of 27,500 tons per year. <br />4. Tailings to a density of 153ft = 1 ton. <br />5. A net operating factor of ± 858 at mill. <br />Twelve years of milling at an 858 time operating factor <br />would create the same approximate volume of tails as a mill <br />operating 10 years at 1008 time factor. <br />Based on this data, we could expect an average maximum depth <br />increase of tailings of 2.0 ft. over the four acre area per <br />year for 12 years, or 24 total feet. Assuming about 8 to 10 <br />feet of clay topsoil to be excavated from the original <br />ground surface for use in construction of the pond retaining <br />embankment and pond covering during reclamation, the <br />approximate average elevation of the tailings would be about <br />14 to 16 feet above original undisturbed ground level. <br />Construction of the tailings disposal area as stated follows <br />the recommendations of the study done by CTL/Thompson, Inc. <br />ITEM #12 <br />A. 8 B. It is our opinion, based on our investigation of <br />the area and that of CTL/Thompson, Inc., that no adverse <br />impact on surface or ground water would occur with <br />construction of the tailings disposal area as proposed in <br />
