The changes were necessitated by the <br />identification of a geologic fault resulting in the slight <br />reorientation of a few pits and by a minor modification of the <br />mining sequence designed to reduce the extraordinary front-end <br />costs required by the permanent regulations for the Ereatment <br />of excess spoil. In our original application, these costs <br />would have been incurred in the first 12 to 18 months of our <br />operations in the Eckman Park area and would have amounted to <br />an expenditure of between $10 and $20 million dollars. Hy <br />slightly alterating the mining sequence, we are able to spread <br />these costs over a period of two and one-half to three years <br />while maintaining our contractual production requirements. <br />The modification to the mine plan involves moving the large <br />Marion 8050 dragline into the area formerly designated as the <br />770 area of Eckman Park as shown in the permit application <br />mine plan rather than the area designated as the 8050 area. <br />The 8050 dragline will operate in the 770 area until the B-E <br />770 dragline is ready to move into this area. At such time, <br />the 8050 dragline will commence mining in the originally <br />scheduled 8050 area. <br />A letter from Leonard Rice Consulting Engineers is <br />enclosed and concludes that the above changes will not require <br />any redesign of the sedimentation ponds and in fact make the <br />existing design even more conservative. <br />
