Minimum Thickness Analysis for Waste Rock Placed Over Spent Heap Leach Ore Material

Document ID: 012413

This tech memo presents Tetra Tech's infiltration and seepagei modeling associated with a waste rocki cover over the proposed Heap Leachi Facility for the Rosemont Cpper Project. The purpose of this modeling was to assess the minimum thickness of waste rock needed on top of the heap in order to minimize meteoric water from infiltrating into the spent orei.
