Due to snow - cover, inspection by <br />DMG or confirmation of project completion by the Division according to the terms of the <br />Consent Decree and Order (Section IV.8a) probably cannot occur until spring. Sunnyside <br />will contact the Division when the area is clear of snow and inspection and confirmation <br />of completion is possible. <br />Sunnyside Gold Corporation (SGC) has completed the B List — Tailings Pond No.4 <br />Upland Groundwater Diversion Project. It was anticipated in the Consent Decree work <br />plan that the BLM would construct the groundwater diversion through the project area in <br />exchange for future use of the area for waste disposal from their planned remediation <br />projects. Since it did not appear that the work would be done by BLM in the allotted time <br />frame, Sunnyside assumed project construction. Following is a summary of the work <br />completed for this project. <br />Sunnyside excavated exploratory holes to determine the depth to bedrock and the location <br />of water sources and paths so a groundwater diversion structure could be placed where it <br />would be the most effective. From these exploratory holes, it was learned that it would <br />not be feasible to place diversion structures at the rock - overburden contact because of <br />
