Abstract:
The Pogo gold mine is located in an undisturbed and pristine natural setting in central Alaska. The reclamation and mine closure plan needs to ensure that water quality is not unduly influenced after mining operations cease. The key components of the plan are underground mine closure and the reclamation of drystack tailings facility. The drainage from the underground should be prevented by sealing the portals properly. The seepage/runoff from drystack tailings facility will be collected at the recycle tailings pond and treated until the water quality meets the standards. The water quality of surface water and groundwater will be monitored for 40 years after mine operations cease.
