Ivanhoe Mines announces today that following the temporary suspension of underground operations at the Kakula Mine announced on May 20, 2025, senior management continues to work alongside world-leading engineering experts to safely and conservatively restart mining operations.Kamoa Copper’s engineering teams are currently updating the short-, medium-, and long-term plans to resume operations on both the western and eastern sides of the Kakula Mine. Subject to dewatering progress, underground mining is expected to restart later this month on the western side of the mine, which remains dry and supported by over 1,000 litres per second of operational pumping capacity.Operations on the eastern side of the Kakula Mine are expected to restart once dewatering is complete. Kamoa Copper has implemented a two-stage plan to dewater the entire Kakula Mine:Stage One involves the installation of temporary underground pumping infrastructure to stabilize and maintain current water levels. Stage One was completed today, with total underground pumping capacity increasing to approximately 4,400 litres per second, sufficient to manage water inflows.Stage Two involves the installation of high-capacity, surface-mounted pumps and new permanent infrastructure to fully dewater the entire Kakula Mine. Stage Two is already underway.
