Response to Preliminary County Comments Received on March 17, 2011 <br />The Chief Portal was built before 1926. The portal was stabilized in 2009 and the bench <br />leading to the portal was graded to remove debris at the entrance. No additional material <br />was removed from the head cut above the adit. There is no sign that stability of the road <br />has been adversely affected by the Chief Portal repair scaling activities in 2009. <br />Adequacy Issue #23 <br />Attachment 6.5.1 suggests steel sets will be constructed at the Lamb Portal. Please clarify <br />whether the Lamb Portal will be re-opened and stabilized with steel sets. <br />Response #23 <br />Timber or steel sets will at some point be constructed at the Chief Portal. All construction <br />activities will be approved by the Mine Safety and Health Administration. There are no <br />immediate plans to open the Lamb Portal. <br />Adequacy Issue #24 <br />Please submit road designs, prepared and certified by a professional engineer, for the proposed <br />access roads to the eleven drill pads. <br />Response #24 <br />Pre-existing roads will be used to the maximum extent to support future surface <br />exploration activities.
