If some consolidation <br />could by attained this would [end to yield higher strength parameters, and conversely, a <br />higher FOS. The 18 inch lift dtickness for the relocated tailings was initially <br />recommended for stability concerns, however, this placement procedure has proven to be <br />very impractical from a constructability standpoint. Therefore, Golder recommends that <br />the lift thickness of the tailings generally not exceed 10 feet. <br />Golder appreciates the ongoing opportunity to provide technical support for the Cresson <br />Project.
