• <br />Roger Day: <br />Carol, you were mentioning the springs in the alluvial, are those subirrigated type areas? <br />Carol Hollowed: <br /><can't hear at all> ... dry right there. <br />Roger Day: <br />I don't know. I haven't followed that area very well. I know that there's generally flow here <br />at the main road and there's a lot of dry sections over here. But, what areas and stuff, I don't <br />know. It's probably intermittent. <br />Jerry Daub: <br />Yes, it is intermittent. But, most of the source of the water is coming out of Water Gulch, <br />which is drainage up above CA and then comes down and joins in the flow of Corral Gulch. <br />Of any of those streams up there, Water Gulch is the one that's flowing the most. <br />Paul Daggett: <br />You don't plan on doing an on- the - ground spring survey at this point, is that right? <br />Jerry Daub: <br />It's not anticipated at this point. <br />Paul Daggett: <br />If not now, it will be required before you go commercial. <br />Paul Osborne: <br />What about subsidence monitoring? <br />Jerry Daub: <br />We went through that a little bit ago, but I'll run through it real quick. Dan was here. We <br />were talking about a casing collar locator, surface elevation monuments, potential for video <br />logging if there's a problem, gamma ray logging, then we've also got the cement bond log. <br />We'll probably end up having the original casing tally that we install in production wells, and <br />then we'll put in several short joints to identify when we're doing the casing collar locators to <br />give us an accurate reading of where those are. So, it will be a combination of a number of <br />those techniques. The Agapito studies that have been done do not indicate any affect on the <br />Mahogany Zone whatsoever. We have a 360 -ft barrier in the Saline Zone between <br />dissolution surface and the very top of the mine horizon, at the upper most resource interval. <br />Paul Osborne: <br />You will have something on the surface? <br />Jerry Daub: <br />Yes, there will be surface monitoring. We'll have an elevation monument at the casing well <br />head. From a surface water perspective, we were thinking that if we see an impact to the <br />alluvial well, we will then initiate a program that will monitor water quality. A grab sample <br />in Yellow Creek. If there's any impact to the alluvial well. <br />36 <br />
