BMRI San Luis Project CDMG Annual Report March 2002 Page 2 The remaining 22-acre unreclaimed area at the tailing facility was used during 2001 to stage reject concentrate from the West Pit water treatment plant and collect underdrain solutions. The staged water was used for vegetation irrigation along the reclaimed tailing surface. The supernatant pond footprint or some portion thereof pending the ability to manage the staged water is expected to continue until West Pit water treatment is completed. If similar success is experienced in 2002 with the center pivot irrigation system, the size of the footprint could possibly be reduced in surface area. Reclamation closure cost estimates were reviewed with the Division during calendar year 2001. The existing financial surety was determined to be adequate to complete the remaining surface land reclamation, fulfill surface water and ground water monitoring obligations, and complete water treatment operations associated with the West Pit and Rito Seco alluvial groundwater systems.
