Mine Shaft/Stope Remediation <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. Additional areas have been found by Ames during construction, <br />however we have not seen a location survey of the new areas. <br />C. Lateral/Slot Remediation <br />• No Activities <br />III.
