A wire with a flag attached has been placed <br />w~_thin each of the pipes. Measurements are taken using a surveyor's transit scope and a <br />yardstick from the top of the metal wire. A static reference point was painted orange on <br />top of the interim dam where the underlying material was bedrock. The difference in <br />settling was found after the difference between the current wire height was subtracted <br />from the height of the transit's scope at the reference point on the interim dam. <br />2) The geogrid layer was left loose on the interim dam side, and at the north and south sides <br />of the tailings layer, and was fastened to the dam's geogrid layer with plastic ties. <br />3) .the ore abandoned on the west side of the mill was used as consolidation material for the <br />tailings; all of it was removed from the pile where it had been previously stored over to <br />the dam, where it was then placed on the tailings. <br />4) A hydraulic excavator arrived at 11:15 a.m. Placement of the borrow began at 3 p.m., <br />after all of the material had been moved within easy reach on the dam crest. Using a <br />toothless bucket, the dirt was placed on the tailings in layers of at least 1E" <br />Standing water in the tailings was removed as much as possible, before the borrow was <br />placed on top. <br />The results of the consolidation monitoring are to be faxed to DMG prior to any further work <br />on 'the tailings layer or dam, or any placement of liner, takes place. Approval of work <br />continuance from DMG must be obtained before any further steps are taken. <br />I & E Contact Address <br />NAME Maxine Stewart <br />OPERATOR ITEC Environmental <br />STREET 9605 W. 49`" Ave. #102 <br />CITY/STATE/ZIP Wheat Ridae, Co 80033 <br />cc: Carl B.
