• Q3 revenue falls 31% to $566.3M after output disruption

• Copper sales dropped 39% due to May seismic event affecting operations

• Higher copper prices offset losses partially; Q4 recovery still uncertain
  

Kamoa-Kakula, the Democratic Republic of Congo’s largest copper mine, generated $566.3 million in revenue in the third quarter of 2025, a 31% drop from the $827.8 million reported a year earlier by its Canadian operator, Ivanhoe Mines.

According to the company’s financial report released on Oct. 29, the mine sold 71,266 tonnes of copper concentrate during the quarter, down sharply from 116,313 tonnes in the same period of 2024. The decline reflects a 38% fall in copper output, as previously reported in early October, following a seismic event in May that disrupted operations.

The incident forced Ivanhoe to lower its 2025 production targets, directly affecting revenue despite a favorable market. Copper prices have risen 17% this year, according to Trading Economics.

Ivanhoe reported an average realized price of $4.42 per pound, or about $9,700 per tonne, for Kamoa-Kakula’s copper in the third quarter, compared with $4.16 per pound a year earlier. The company said fourth-quarter results will depend largely on how quickly production recovers over the remainder of the year.

Kamoa-Kakula is jointly owned by Ivanhoe Mines and China’s Zijin Mining, which each hold 39.6%, while the Congolese government retains a 20% stake.
