The Elkton workings area is considered part of the LOB area. <br />• Mechanical problems slowed progress during the week. The drillers had a <br />total of three rigs on site, two operating and one down due to mechanical <br />problems. <br /> <br />aab .? .

Mine Shaft/Stope Remediation <br />• AMEC completed a follow-up check of mine workings #18, #19 and #20 <br />within the LOB Pad area. Remediation of these mine workings was not <br />started by the end of the week. The mine working locations are shown in <br />the Attached Figure 1. <br />• Mine Working No. 27 located within the limit of the LOB/Delivery Road <br />left of Station 38+00 was backfilled during the week. This mine working <br />does not require remediation per engineering (John Lupo) but was checked <br />in the field by Amec (J. Namlick) as the location was backfilled. The <br />opening to the mine working was initially backfilled with oversize and then <br />closed during subsequent fill lifts across the location. This location is shown <br />on the attached Figure 1. <br />• Some of the mine workings identified in Figure 1 will be remediated as a <br />result of the locations being removed following excavation to grade. All <br />mine workings, whether requiring remediation or not as determined by <br />engineering, will be checked and verified in the field during construction <br />activities. <br />Sheet 3 of 10 <br />LOB Weekly Report WE 02.21.09
