Kamoa Kakula Copper Guidance Cut Highlights DRC Supply Recovery Risk

Kamoa Kakula

Kamoa Kakula copper guidance has been lowered for 2026 after seismic shocks forced Ivanhoe Mines to drain and rebuild parts of the complex in the Democratic Republic of Congo. The Canadian miner now expects the asset to produce 290,000–330,000t of copper in 2026, down from its previous target of 380,000–420,000t.

The cut also affects the medium-term outlook. Ivanhoe’s 2027 target of 380,000–420,000t remains below the mine’s pre-shutdown guidance of 500,000–540,000t, although the company still expects output to exceed 500,000 t/yr from 2028.

Kamoa Kakula copper guidance matters because the project is one of the most important growth assets in the global copper pipeline. Any slower recovery from the complex affects expectations for DRC copper supply at a time when electrification, grid investment and industrial demand continue to support long-term copper consumption.

Seismic Damage Raises Costs and Delays Copper Recovery

Ivanhoe’s revised guidance shows how quickly geotechnical risk can affect large underground copper operations. The need to drain and rebuild the mine has delayed the return to earlier production targets and increased the cost of the recovery path.

Kamoa Kakula’s cash costs are now expected at $2.60–$3.00/lb this year and $2.10–$2.50/lb in 2027. That is higher than earlier expectations of around $2/lb, reflecting the combined impact of disruption, rebuilding work and inflation across key inputs.

The wider DRC copper belt remains one of the fastest-growing copper regions in the world. The country lifted output by 10% to 3.4mn t last year, but rapid growth still depends on reliable acid supply, power, transport and mine-site execution.

Sulphuric Acid and Lobito Rail Shape DRC Copper Economics

Sulphur and sulphuric acid costs remain a major pressure point for DRC copper producers. A squeeze in Middle East sulphur flows pushed delivered sulphur prices close to $900/t into Kolwezi, increasing acid costs for leaching operations.

Ivanhoe’s new smelter could reduce some of this exposure. The smelter began producing anodes and sulphuric acid late last year and could add up to 700,000 t/yr of acid once it reaches steady operation.

Transport capacity is another constraint. The first low-carbon anodes moved out of Kamoa Kakula through the Lobito corridor in February, but available rail freight still falls short of the complex’s full logistics needs.

These bottlenecks show that DRC copper growth depends on more than orebody quality. Acid integration, rail access and underground transport capacity will decide how quickly Kamoa Kakula can return to higher output.

The Metalnomist Commentary

Ivanhoe’s guidance cut shows that the copper market cannot treat DRC growth as risk-free supply. Kamoa Kakula remains a world-class asset, but seismic recovery, acid costs and logistics will determine how fast its tonnes return to market.
