No evidence of springs nor seeps <br />was observed. <br />Observation of Fill Construction: (Description of material, compaction, lift thicknesses, slopes, and <br />construction methods) <br />Coarse to fine-grained development waste rock has been placed and compacted according to <br />approved plans. Compaction testing was done by CTL -Thompson on May 28, 2012 demonstrating that <br />refuse placement has been conducted in accordance with plan requirements. No refuse placement has <br />occurred since the May 2012 compaction testing. <br />Indications of Potential Failure or Instability: <br />Surface and outslopes of the pile were inspected for visible signs of potential failure or instability. None <br />were observed <br />Threat to Human Life or Property: <br />Failure could impact persons or equipment on or adjacent to the disposal area. <br />No threat was observed. . <br />Potential Harm to Land, Air, and Water Resources: <br />Failure could impact the Purgatoire River or areas adjacent to the disposal area. <br />No adverse conditions were observed. <br />Page 3 <br />
