RENNER: No, actually --- it would <br />be the west pit area, okay? And the aquifer we're <br />concerned with is the confined ore zone aquifer and <br />that lies -- it's highly confined by an overlying <br />green clay layer and is not tributary at all to <br />the Rito Seco. <br />MR. HOLDER: And then let's look at <br />the worst case scenario on the leach itself on the <br />heap. The liner breaks for some reason. A. deer <br />steps on it or something, and the alarm is triggered <br />or there is leakage in the inside liner, the gravel <br />blanket, and possibly you can get some cracking in <br />the second liner which is a clay and could, from <br />wetting and drying, crack. Now, what's the drill? <br />MR. RENNER: Well, there's a stepped <br />response depending on how much solution we see within <br />the secondary -- or the leak detection system. <br />The ultimate response would be to <br />initiate pumping out of the secondary recovery or <br />leak detection system back in either to the <br />pregnant pond or onto the heap itself. <br />If we had a leak of duration and <br />quantity which is fairly significant, the company <br />
