EPBC 2023/09556 Hemi Gold Project
Northern Star is planning to develop the Hemi Gold Project proposal located approximately 85km south of Port Hedland in the Pilbara region of Western Australia. The Project involves the excavation of open pits, mine dewatering, surplus water management including reinjection and controlled discharge and associated supporting infrastructure. The Project will commence with approximately a two-year period of dewatering, earthworks (including pre stripping), and construction activities, followed by operational pre-strip mining and processing.
