ABSTRACT
ABSTRACT: The Grouse Creek gold-silver deposit in central Idaho operated from 1994 to 1997. Site reclamation activities began in 2000 after permanent closure was announced. Since 2000, approximately 60% of the site has been reclaimed. Tailings impoundment reclamation began in 2006 with consolidation studies. The tailings impoundment reclamation plan includes placement of base fill over tailings, encapsulation of tailings with a synthetic liner, and placement of 4 foot earthen cover over the liner. Surface water will be managed through an energy dissipator, and the reclaimed impoundment surface will serve as a floodway for storm waters metered through a permeable weir to receiving streams. In addition, a clay cover to reduce infiltration will be placed over the south embankment surface.
