Colowyo C-1981-019 <br /> 20 May 2008 <br /> Pg 5/5 <br /> General Mine Plan Compliance (cont.): - The 114 shovel operation was currently <br /> working on the box-cut area of the South Taylor Pit. <br /> - The 115 excavator was also working on the box-cut area of the South Taylor Pit. <br /> - The mining at the Colowyo Mine appears to be progressing as discussed and <br /> approved in the PAP. <br /> Air Resource Protection: - The mine was very wet on 26 February 2008 so there was no <br /> problem with fugitive dust. The majority of the haul roads had dried out by 27 <br /> February 2008 so there was some dust being generated. Please remember that even <br /> though it is winter, it may still be necessary to water the haul roads, as conditions <br /> dictate. <br /> Excess Spoil: - The reclaimed portions of the West Pit fill were well vegetated and <br /> appeared to be stable at the time of the inspection. There were no erosional <br /> problems noted on the fill. The top 75 feet of the fill (approximately) will need to be <br /> removed and hauled into the West Pit to achieve AOC and the approved PMT. <br /> - The Streeter fill was well vegetated and appeared to be stable at the time of the <br /> inspection. No erosional problems were noted on the fill. This pile has gone through <br /> a Phase II bond release. The fill was well vegetated at the time of the inspection. <br /> - The Section 16 fill was inaccessible at the time of the inspection due to mud. The <br /> pile should be accessible in June. <br /> - The operator has begun construction on portions of the East Taylor fill. The area is <br /> clear of topsoil and ready for fill. The underdrain location has been constructed and <br /> Colowyo is waiting to get into more competent and larger rock before starting to <br /> dump into the fill. The underdrain will be constructed using gravity-sorted rock that <br /> will be wing-dumped into the fill. The large rock will then be covered with filter fabric <br /> then the excess spoil. It is anticipated that the underdrain will be completed in <br /> stages as competent rock is encountered. <br /> Overall, the operations and reclamation at the Colowyo Mine are being conducted <br /> in accordance with the approved plans contained within the PAP. The operation is <br /> doing a good job ensuring compliance with all of the Rules. <br /> I�� <br />
