Spoil Fill #8, <br />June 28, 2008 <br />Page 2 <br />FILL PLACEMENT <br />Fill placement has been completed in accordance with the approved plan. No additional fill placement is <br />anticipated <br />COVER MATERIAL <br />Final fill configuration has been established and topsoil material has been placed on the excess spoil-fill. <br />The area was mulched and seeded in the fourth quarter of 2003. Soil was placed and spread on the upper <br />most surface of the fill in May of 2004. During the second quarter of 2005, areas disturbed by maintenance <br />of the armored down-drains were seeded using certified weed free straw and the approved rangeland seed <br />mix. The construction access road east of the east down-drain was hand mulched and seeded during August <br />of 2006. <br />STRUCTURAL INTEGRITY <br />The entire excess spoil fill facility was examined for signs of failure and instability such as tension cracks, <br />ground movement, springs and seeps, and standing water. No indication of potential instability was <br />observed <br />DOCUMENTATION AND OTHER OBSERVATIONS <br />Early summer conditions prevail. A small i9.5acre) parcel is ready for seeding later this year as conditions <br />permit. This parcel is located on the second bench just west of the west down-drain. Minor erosion is <br />occurring midway along the east armored down-drain and should be addressed while equipment is on site <br />later this year. Overall, site is in good condition except as noted <br />CERTIFICATION <br />This inspection was conducted by Ronald G. Thompson, a qualified professional and MSHA certified <br />inspector of earth and rockfill embankments and impoundments, under the direction of Mr. Charles <br />McGlothlin, a registered professional engineer licensed in the State of Colorado. <br />This is to certify, to the best of my knowledge and belief; that Fill No. 8 construction and placement, as <br />noted since the previous certification and as determined during this inspection and discussions with mine <br />personnel, is in accordance with designs as proposed by CTL Thompson in their report dated April 27 and <br />amended July 27, 2001 and as approved by the Division of Minerals and Geology. <br />Ronald G.
