It loses its head quite quickly, which is <br />again characteristic of a small, relatively <br />impermeable, in comparison to some of the deeper <br />stuff in the valley. <br />MR. HOLDER: Is there a perched water <br />table? <br />MR. HALEPASRA: Perched is a -- might <br />be an expression that one would use. It seems to be <br />isolated from the hydraulic community around it, and <br />I think, as Gary has indicated, as the pit is opened <br />up and there's actual opportunity to pump the system <br />down and to understand it better, whatever is <br />necessary will be modified to satisfy the plan that's <br />been submitted. <br />MR. DANIELSON: One final question <br />I had here on the same subject is what is the <br />relationship, if any, between this potential seepage <br />from the Rito Seco and the potential stability <br />problems that lead to this rock wall being needed on <br />the south side of the pit? Could the seepage <br />exacerbate the stability problem? <br />MR. JIM JOHNSON: No. The stability <br />problem is related only peripherally to the seepage <br />
