<br /> <br />moved from the north side of the Rito Seco the south side. The net <br />effect of these changes is an overall reduction in the total waste <br />rock disposal area and relocation of certain waste rock areas <br />further from Rito Seco Creek. However, the design criteria, <br />stability, geochemistry and reclamation plans and criteria remain <br />unchanged from those approved in the existing reclamation permit. <br />The mined ore will be hauled to the mill and will be <br />stockpiled for sorting and beneficiation. The new facility will <br />include a crushing and grinding circuit, a cyanidation ~:ircuit, a <br />gold recovery circuit, and a tailings treatment circuit, As with <br />the previously approved mill, the design contemplated in the <br />amendment is a closed circuit operation with an internal curbing <br />and collection system to ensure total containment in the unlikely <br />event of a tank rupture or leak. The milling procese~ produces <br />tailings consisting of finely ground rock and residual process <br />water. The mill facility includes a tailings treatment circuit <br />which will serve to treat the tailings prior to disposal. The <br />treated mill tailings will be piped from the mill in slurry form <br />for disposal in a fully lined tailings disposal facility located <br />southwest of the mill in the same general area as the currently <br />approved heap leach facility. The entire tailings disposal <br />facility has been designed as a fully lined, nondi.scharging <br />facility utilizing a composite liner consisting of compacted <br />subsoil material overlain by a synthetic geomembrane liner. The <br />tailings facility has been designed conservatively to provide <br />storage capacity for the total volume of tailings produoed in the <br />3 <br />
