Montana Resources Halts Berkeley Pit Water Pumping Due to Wall Instability
WATER INFRASTRUCTURE & DESALINATION
Montana Resources has paused water pumping from the Berkeley Pit due to instability detected in the pit wall, which could lead to a small slide affecting access to the pump station. The company is relocating pumping infrastructure to the south ramp to address this risk, a process that may take months. Meanwhile, the water level in the pit is under control through ongoing management efforts from a 2019 Pilot Project aimed at treating and discharging contaminated water.
