Infiltration, Seepage, Fate and Transport Modeling Report - Revision 2

Document ID: 
tetra-tech-infiltration-seepage-fate-transport-rev-2-201206
Year Published: 
2012
Summary: 

At the end of the mine life, final reclamation of the site will include demolition and closure of the Plant Site facilities and final regrading and revegetation of the Rosemont Ridge Landform. The Rosemont Ridge Landform is the consolidated and contoured earthen structure consisting of the Waste Rock Storage Area, the closed Heap Leach Facility encapsulated with waste rock, and the Dry Stack Tailings Facility, also encapsulated with waste rock. The Open Pit will remain as an excavation subject to natural processes of wind and water erosion, and geochemical weathering processes.

This investigation evaluates the environmental consequences of developing the Rosemont deposit, with a focus on the potential to impact the regional groundwater system following completion of the closure process. Post-closure impacts of the Open Pit have been characterized in a separate report titled Geochemical Pit Lake Predictive Model, Revision 1 for Rosemont Copper Project (Tetra Tech, 2010a). This report presents the results of the infiltration and seepage, and fate and transport modeling for the proposed Waste Rock Storage Area, the Heap Leach Facility, and the Dry Stack Tailings Facility.
