Cripple Creek & Victor Gold Mining Company <br />Mill Site Earthworks Project <br />Final Report <br />Quality Assurance Monitoring & Test Results <br />January 31, 2014 <br />2.7 Drain Cover Fill <br />TMI d <br />Ames began placing DCF October 2012 and completed placement December 2012. <br />Ames processed DCF from December 2011 through February 2012 and again from <br />September 2012 through October 2012 by screening crushed Cresson Ore over a <br />vibrating 1-1/2 inch screen to remove oversize material from the borrow source. Ames <br />placed approximately 108,294 cubic yards (neat line) of DCF to Project Specifications. <br />DCF was placed in a minimum 2- foot -thick lifts over the geomembrane and in a 4 -foot- <br />thick lift where Caterpillar 740 haul trucks travelled over the geomembrane. During fill <br />placement, Polyvinyl Chloride (PVC) grade markers were placed at grade breaks and <br />on a maximum 50 foot wide by 50 foot long grid. After DCF placement, PVC grade <br />markers were removed and Ames performed any required additional grading. Ames <br />placed DCF in an uphill direction on any slopes steeper than 4H:1 V. <br />M <br />
