EXHIBIT D - MINE PLAN <br />~ Exhibit D of the approved San Luis permit is being amended to change <br />the method of ore beneficiation. The currently approved permit allows half <br />of the ore to be milled in a conventional mill circuit with-c~anidation <br />of the concentrates and dry tailings disposal and the otheM half of the <br />ore to be subjected to leaching in a cyanide heap leach. This amendment <br />proposes to extract the gold from the ore through the use of a carbon in <br />leach circuit in the mill with disposal of the tailings through managed <br />thin layer deposition. This exhibit also addresses revisions to the mill <br />process description as a result of the change and revision:c to three of <br />the waste rock disposal areas. The mining plan remains unchanged from the <br />approved permit and is therefore not discussed in this amendment. The <br />mining plan for the San Luis Project can be found in Section D.2 of the <br />approved permit. <br />D.1 Site Geoloav and Seismicity <br />The geology and seismicity of the site are as described in <br />Section D.1 of the approved permit. The pseudostatic: coefficient <br />used in the reclaimed tailings disposal area configuration stability <br />calculations remains unchanged from the approved permit value of <br />0.08 g, however a more conservative coefficient of 0.15 g has been <br />used to evaluate the stability of the tailings disposal area during <br />the operational period. <br />D.2 Mine Plan <br />The mine plan for the San Luis Project remains unchanged from <br />the plan approved in the permit and is as described in Section D.2 <br />of the approved permit. <br />D-1 <br />
