Ivanhoe Mines has stopped activities at the Kakula underground mine, located at its Kamoa-Kakula copper complex in the Democratic Republic of Congo (DRC). The firm decided the halt on May 18 but officially announced it on May 20.

Operations were halted after seismic activity was recorded in the eastern section of the mine. There were no casualties, and all personnel were evacuated. The Phase 1 and 2 concentrators still run, at reduced capacity, processing ore from surface stockpiles. As of April 30, these stocks stood at 3.8 million tonnes, at an average grade of 3.2% copper. The Phase 3 concentrator and Kamoa underground mine continue to operate normally.

Geotechnical experts are inspecting the underground infrastructure. The western zone of Kakula has already been declared safe, while the eastern zone remains under evaluation.

Despite the disruption, Ivanhoe has not revised its production targets for the year; it still eyes an output of 520,000–580,000 tons of copper in 2025, for the whole complex. However, the impact of this suspension will depend on its duration. For now, it is unknown when operations will resume.
