This report presents the results of a regional groundwater flow model developed for the Rosemont project. This geologically based, numerical flow model predicts the formation of a pit-lake within the proposed Rosemont Open Pit following the cessation of dewatering. Additionally, the pit-lake will be a hydraulic sink, meaning that water will flow into and not out of the pit due to the high evaporation rate of the area.
