Conversely, if tiie trench reins -- if we do not see expected <br />inflows or the inflows are significantly 1es, than what is anticipated <br />currently, the necessity for the trench may pot exist. At which point, a <br />technical revision could be submttted with s~Dstantive of hydrologic data -- <br />ar supporting hydrologic data to substantial! not creating or building the <br />trench or the slurry wall. i <br />i <br />KR. BARAY: Just to clarify, because I'm a little behind an some of ,~ <br />this. The slurry wall and the trench and all this stuf' on the West Pit, is , <br />all in an area that's going to be mined, but !their processing of cyanide will <br />i <br />not be present at that location. <br />I <br />MR. RENNER: No, not at ail. ,I <br />.I' <br />MR. BA0.RT: I aW correct? <br />MR. RENNER: Tou're exactly correct. <br />s <br />_ __ ._.MR.._BA0.RY.:._ And. you have identified that'jthere are no toxic or acid <br />i <br />forming materials in the native rode materialsI <br />MR. R°HNEA: Tes; that's correct. As fan as the typical design which was <br />submitted, the slurry wall would ba keyed to 1~e Santa r-e Conglomerate at the ' <br />point where it is well cemented. The wall will be about three feet wide, it <br />will be caopacted so permeability of 10 to theiminus 1 c_ntimeters per second <br />is achieved. The actual depth of Lhe wall wttlll be variable dependant an <br />topography and lithologic characteristics of tpe Santa Pe. <br />The fourth outstanding issue that we dtsc~ssed with the Company was the <br />amount of financial warranty necessary for thi# site. Tne Division has <br />calculated the financial warranty and we have ~ome up with a figure. The way <br />that the Company would like to have tha warranty and, acwally, the whole <br />i <br />
