146 <br />1 could be lowered inside a casing string. To prevent <br />2 hanging inside the cases, centralizers can be used. <br />3 And there's a couple photos of those centralizers. <br />4 And the number one -- if the operator <br />5 is concerned about dangling the pump string in the N <br />6 1 shaft, there are alternative possibilities. One <br />7 is the Number 2 shaft which doesn't involve going <br />8 2,200 feet in depth. <br />9 Drilling to go hit a 74-foot -- <br />10 square-foot at a depth of 300 feet represents a <br />11 challenge. Now, the operator didn't bring this up <br />12 today, so perhaps they have reconsidered. But there <br />13 are numerous examples of drilling to intercept small <br />14 targets. <br />15 It's common practice not just in the <br />16 mining industry but in the construction industry. <br />17 Some of them have been pretty high profile and in <br />18 the news lately here in Colorado. For instance, <br />19 Leadville Mine Drainage Tunnel, 300 foot large <br />20 diameter well that's drilled into the Lakewood Mine <br />21 Drainage Tunnel. <br />22 Oil shale projects in western <br />23 Colorado. 19-foot holes with 2 foot deviation. <br />24 Cheeseman Dam construction project, Denver Water. <br />25 We have folks here who are probably closely familiar
