Portia Mine Expansion Numerical Groundwater Model

WGA completed a review of the hydrogeological and pit dewatering data to provide an updated water balance to support the revised mining schedule.

Once the model was complete the information was used to update the impact assessment and prepare an updated Program for Environment Protection and Rehabilitation (PEPR) to be submitted to the Department of State Development (DSD) for assessment along with an updated supporting Groundwater Monitoring and Management Plan (GMMP)
