Area C as a result of eliminating the previously approved Area A, but the <br />designs for both remain the same. The East Pit Disposal Area also remains <br />unchanged. Area B has been renamed Area A and has been downsiaed. The South <br />Waste Rock/Tailings Disposal Area has also been redesigned to contain only <br />waste rock and to accommodate the location of the constructed mill haul <br />road. A sixth area designated as Area D has been added south of the Rito <br />Seco between the mine haul road and the eastern permit boundary. See Figure <br />C-1 for the location of all waste rock disposal areas. The waste rock <br />disposal area design changes are discussed in Section D.3 of this <br />amendment. <br />The mined ore will be hauled to the mill and will be stockpiled for <br />sorting and beneficiation in the mill. The mill facility will consist of <br />a crushing and grinding circuit, a cyanidation circuit, a gold recovery <br />circuit and a tailings treatment circuit. Milling operations are discussed <br />in detail in Section D.5. <br />The milling process produces tailings, consisting of )'finely-ground <br />• rock (80 percent minus No. 150 U.S. sieve size) and residual process water. <br />Under the proposed mining schedule, about 12.2 million ton# of tailings <br />will be produced. The tailings will be passed through a treatment circuit <br />in the mill prior to disposal. The treated mill tailings }ill be piped <br />from the mill in slurry form (approximately 50 percent solids for disposal <br />in alined tailings disposal site located southwest of the mill in the same <br />general area as the currently approved heap leach. The tailings facility <br />has been designed to provide storage capacity for the total tailings <br />produced using the managed thin layer deposition technique. The tailings <br />disposal facility and its operation are described in more detail in Section <br />D.6. <br />Reclamation plans for the project facilities will remain essentially <br />the same as previously approved. Waste rock disposal area reclamation is <br />unchanged and is discussed in Section E.3 of the original permit. Tailings <br />reclamation is discussed in Section E.2 of this amendment. <br />i <br />Pre-existing facilities such as the old heap and the test heap will <br />2 <br />
