Spent ore elevations were maintained above the drain cover fill <br />grade by at least 20 feet for 793 haul traffic. <br />Spent ore was placed and compacted as engineered fill beneath the footprint of the ADR2 <br />foundation.

The pipes were <br />wrapped with geomembrane before burial per project plans and site instruction. <br />Snow was removed from the access road and the security area, hauled, and dumped on the <br />north side of the ADR2 platform outside of the footprint. <br />Subgrade: Phase 2 rough subgrade preparation occurred.
