trials are attempted on salvaged topsoil stripped from the open pit <br /> aromas during the summer of 1988 . <br /> As described in Amendment No. 3 , two open pits in the Sunnyside <br /> Darin will be started in 1988 . The Lake Emma glor;: hole will remain <br /> ur__eclaimed, and it will be used as an ore pass tc the mine for <br /> ha--lage to the Mayflower Mill . Upon completion o-f the open pit <br /> project, the waste rock generated by the open pits will be used to <br /> ba=kfill the open stopes . <br /> Ta_ linas Pond No. 4 Area <br /> Normal maintenance was conducted on the Tailin=s Fond No. 4 <br /> fa=•ilities ( Plate 3 ) . Drainage ditches above the .ailings ponds were <br /> pr--L.ned of young aspen trees and other accumulated -vegetation, and <br /> wa-er collecting in the pump back pond was periodically pumped to the <br /> reservoir. A dust suppressant was sprayed on the pond outslope twice <br /> du=-ing the summer of 1987 . Repeat spraying is required by the <br /> current modified centerline raise method which adds new sands to the <br /> po_d outslope each successive pour. <br /> The embankment elevation had reached 9413 feet as of July 9, 1987 <br /> any several alternatives are being considered in order to extend the <br /> li_e of the impoundment. Test drilling of the slimes and sands was <br /> cc-ducted during October 1987 to investigate the feasibility of <br /> raising the berm by the upstream method. If this alternative proves <br /> ec=nomically and technically sound, a permit technical revision will <br /> be submitted to the Division detailing the required land disturbance <br /> an� modifications to the reclamation plan which will be entailed. <br />
