Drilling <br />• Rockbreakers have completed drilling in the area of the Lower and upper <br />Elkton Mine workings by mid-week. The Elkton workings area is <br />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 />B. Mine Shaft/Stope Remediation <br />• AMEC completed a follow-up check of mine workings #19 and #20 within <br />the LOB Pad area. Remediation of these mine workings was not started by <br />the end of the week. However due to the cut within the LOB pad it appears <br />the mine workings #20 has been removed. The mine working locations are <br />shown in 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 />C.
