REVEGETATION <br />• Seeding and Shrub Planting <br />SCC observed and reviewed revegetation success in select portions of areas originally seeded in <br />1997, 1998, and 1999 and decided that the revegetaHon success for cover and production was <br />limited due to poor stand establishment Subsequently, inter-seeding was conducted on 167.4 <br />acres of previously seeded azea during the fall of 2006. The seed mix used is shown on the <br />following Table 06.2, Interseeding Seed Mix. The locations of the areas interseeded are shown <br />on the 2006 Annual Reclamation -Seeded map. <br />Table 06.2 <br />Interseeding Seed Mix <br />Drill Rate <br />Suedes Name P.L.S.

Canada <br />thistle was the primary tazget spedes, with lesser activity duected towards areas of hounds tongue <br />and whitetop. The weed conro! azeas will continue to be monitored in 2007 for effectiveness <br />and necessary retreatment <br />See the attached weed control daily log spreadsheet for more detailed description of the 2006 <br />herbicide application (actual log is on file at the mine site) and the 2006 Weed Control Areas map <br />for locations of spraying azeas. <br />3 <br />
