Smelter Ramp-Up Delayed Amid Seismic Setback

Ivanhoe Mines

Ivanhoe Mines has withdrawn its 2025 copper production guidance due to seismic disruptions at the Kakula mine in the Democratic Republic of Congo. The underground operations at Kakula were initially suspended on May 18, resumed briefly, and were suspended again on May 25 after further seismic activity. This operational volatility prompted Ivanhoe to review its previously announced copper production range of 520,000–580,000 tonnes for the year.

Water Inflow Escalates, Surface Operations Continue

The seismic events also increased water inflow at the site, necessitating new dewatering infrastructure to sustain future mining activities. As a result, the company also suspended its ramp-up schedule for the newly built direct-to-blister smelter, which was slated to produce its first copper anode in July. While underground mining is halted, surface concentrators remain active by processing stockpiled ore, and the nearby Kamoa mine remains unaffected.

The Metalnomist Commentary

Seismic risk now emerges as a critical operational challenge for copper mining in Central Africa. Ivanhoe’s decision highlights how geological instability can derail even well-planned projects. Investors and analysts will be watching closely as this event affects both copper market expectations and smelting capacity timelines.
