Keffelew, Berhan <br />From; Keffelew, Berhan <br />Sent: Wednesday, September 28, 2005 5:29 AM <br />To: Humphries, Bruce <br />Cc: Posey, Harry; Waldron, Tony <br />Subject: CC&V UPDATE <br />Sensitivity: Private <br />was informed by CC&V yesterday around 4:00 p.m that Dr. John Lupo, Golder AND <br />ASSOCIATES INC, Project Manager for the Leach Pad construction will be on site to recommend <br />permanent fix for the area on Thursday 9129, as I told you (Bruce) I plan to attend the meeting. <br />One of the solutions mentioned is to tie in the solution application pipes, to a tertiary line away <br />from the interface area. Whatever the solution is, even though it dos not affect the DMG , <br />because this only applies to application of process solution, any spill even if it does not meet the <br />reportable criteria as this was the case, is our concern. Until and unless a permanent solution to <br />the problem is found, when the ore is loaded in the up gradient portion of Phase IVC, more <br />solution will report to this area causing a spill outside of the containment field. Since we know the <br />solution application rate, we know the permeability of the ore, a bit suspect, but as I said before, <br />whet they can not leach, we do not need to detoxify, we also know the surface area, so <br />calculating the total amount of solution that will report at any given time is simple. There is no <br />reaching from air in this case. However we can not allow them to place are until a permanent fix <br />is in place.CC&V agrees not to place ore in the up gradient portion of the pad until a permanent <br />solution is in place. I have also asked any changes to the solution application system, to be <br />submitted as a technical revision so DMG has a record of it. <br />
