Boz 5280 <br />Durango, CO R 1302 <br />RE: CARBON JUNCTION MINE SANDSTONE SLOPE <br />Dear Jim: <br />I am attaching a copy of the slope analysis done by Lambert & Associates, as <br />required by Harry Ranney of the Division of Mining & Geology. The conclusion, as 1 <br />read it, is that the material will stand (at 4 feet thick) as long as it is in the dry state. When <br />it gets wet the safety factor will drop to 1.0 or lower and the cover material can be <br />expected to fail (slump). <br />[f you want me to forward this on to Harry, let the know, or you can do it. <br />V r tntly yours, <br />arry L. Go , P.E. <br />HLG/ws <br />
