Copper Supply Chain Fragility Is Underpriced Despite Price Rally

Ivanhoe

Copper supply chain risk is still being underpriced even after London Metal Exchange prices rallied above $13,000/t, according to Ivanhoe Mines chairman Robert Friedland. He warned that higher prices alone will not quickly unlock new mine investment or solve the operational bottlenecks now shaping copper supply.

The copper supply chain is facing a more complex problem than headline market balances suggest. Friedland pointed to sulphur, sulphuric acid, diesel and other critical inputs as increasingly important constraints for mining operations, especially in Africa.

The copper supply chain is particularly exposed in the Democratic Republic of Congo, where a large share of production depends on acid leaching. If sulphuric acid availability tightens further, Friedland said about half of the DRC’s low-grade leached copper could be at risk unless higher copper prices offset sharply higher acid costs.

This warning comes as the Middle East conflict affects copper markets indirectly. The immediate threat is not concentrate supply, but sulphur-linked cost inflation that can raise operating costs for solvent extraction and leaching operations.

Sulphuric Acid and Diesel Risks Expose Mining Cost Vulnerability

Sulphuric acid has become a central issue for copper supply because much of the DRC’s production relies on acid leaching. A prolonged disruption in sulphur flows could affect roughly 3mn t/yr of DRC copper output, making the country one of the most exposed parts of the global copper market.

The DRC’s vulnerability is different from that of traditional concentrate producers. Concentrate supply depends on mining, milling, logistics and smelter demand. Leached copper also depends on steady sulphur or sulphuric acid access, which creates another layer of supply-chain risk.

Ivanhoe’s Kamoa-Kakula complex is unusually positioned because it produces sulphuric acid as a by-product rather than relying only on external supply. The operation produced more than 100,000t of sulphuric acid in the first quarter of 2026, with annual output expected to reach 600,000-700,000 t/yr once the new smelter is fully ramped up.

That acid production gives Ivanhoe a strategic advantage. It can reduce exposure to imported acid costs while supporting copper output in a market where other DRC producers may face tighter reagent availability.

Diesel is another operational risk. Remote mines depend on diesel for haulage, power generation and logistics, especially where grid access is weak or transport routes are long.

Friedland said highly exposed mining firms should consider securing up to a year of diesel supply. He also argued that the DRC may be less vulnerable than some expect because refined products can arrive through India, Nigeria and southern Africa.

Still, the full operational impact may not yet be visible. Supply-chain shocks often appear first through higher costs, longer lead times and working-capital pressure before they become production losses.

This is why the copper market may be misreading risk. Visible inventories and annual balances can suggest moderate surplus, while the physical supply chain becomes more fragile beneath the surface.

A copper price above $13,000/t helps margins, but it does not immediately create acid, diesel, spare parts, qualified labour or new mine capacity. Mine investment still depends on permitting, capital cost, political risk and long development timelines.

AI, Data Centres and Critical Metals Raise Copper’s Strategic Value

Friedland linked copper’s long-term importance directly to electrification, cooling systems, data centres and artificial intelligence. These sectors are turning copper from a conventional industrial metal into a strategic infrastructure material.

AI data centres need large amounts of power infrastructure. That means more copper for grids, substations, transformers, cooling systems, cabling, backup power and electrical distribution.

The growth of AI also reinforces demand for metals beyond copper. Friedland highlighted gallium, scandium, dysprosium, rhenium and tantalum as thinly traded materials with low liquidity but high industrial dependence.

This is an important market signal. The next phase of industrial competition will not depend only on bulk metals. It will also depend on access to small-volume strategic materials that support semiconductors, aerospace, defence, magnets and high-performance alloys.

Copper remains the anchor metal because it connects electrification, grid expansion, industrial automation and data infrastructure. Friedland described copper as the “king of metals” because no large-scale energy transition can move without it.

However, copper’s strategic value also exposes the market to policy pressure. The US is beginning to understand mining’s national security role more clearly, especially as domestic supply concentration and import dependence become more visible.

Market participants expect moderate global copper surpluses this year, helped by last year’s supply windfall. But US physical balances are expected to remain tight, with the CME-LME arbitrage reopening to encourage flows into the country.

That regional tightness matters. Copper may look balanced globally, while specific markets face procurement pressure because of tariffs, logistics, exchange spreads, domestic manufacturing needs or strategic stockpiling.

The broader lesson is that copper pricing must account for supply-chain resilience, not only mine output. A mine that lacks acid, fuel or logistics capacity cannot deliver metal reliably, even if ore is available.

For investors, this strengthens the value of hard assets with low obsolescence. Mines, smelters, acid plants, power infrastructure and logistics corridors are becoming more valuable as supply chains become less predictable.

For manufacturers, copper procurement is becoming a strategic function. Buyers linked to grids, data centres, defence, cooling systems and energy infrastructure will need more secure supply agreements, not only exposure to exchange prices.

The Metalnomist Commentary

Friedland’s warning cuts through the headline copper rally: the market is pricing metal, but not enough supply-chain fragility. Copper’s next constraint may come less from ore availability and more from acid, diesel, logistics and the minor metals needed to build the electrified economy.
