01 THE SETUP

While it doesn’t dominate copper news, Central Africa has become a recurring theme in the headlines.

The latest installment — late last week, Wood Mackenzie principal analyst Vidhya Sreelalan told Mining Weekly that Central Africa — notably, the Copperbelt, a mineral-rich arc running through the DRC and Zambia — is emerging as a key player to step up copper supply.

This week, we’re taking a whirlwind tour of the region to look at what’s behind the Central African story beyond the usual “exceptional grades” talking points we all know by now.

02 WHY IT MATTERS

The expected copper shortfall is increasingly a construction problem rather than a geological one. Meanwhile, Western majors are largely holding back, leaving risk-tolerant Chinese and other players to push into resource-rich Africa where a disproportionate share of the actual building is happening: between now and 2029, production is tipped to grow 32.8%.

That makes the Copperbelt one of the most important swing regions for near-term global supply, and worth understanding beyond a grade table.

03 THE DECODE

Below the “exceptional grades” headline, five things are happening, each with an implication that surface coverage tends to skip.

1. The near-term tonnage is brownfield, and that’s why it’s credible.

The supply arriving before 2029 comes almost entirely from expansions at existing mines: First Quantum’s $1.25bn Kansanshi S3, commissioned in August 2025; Barrick’s $2bn Lumwana Super Pit, on schedule for first copper in Q1 2028; CMOC’s $1.08bn Kisanfu Phase 2, board-approved and building toward 2027.

The point worth registering: because these sites already hold permits and infrastructure, their tonnes carry lower execution risk. When you read that Africa supplies half of supply growth, this funded brownfield core — not any single discovery — is what backs the number.

2. The region is starting to process its own metal.

Ivanhoe’s Kamoa-Kakula now runs Africa’s largest copper smelter, turning out 99.7%-pure anodes on-site, moving the complex from shipping concentrate to shipping finished metal. Beyond captured margins and sharply improved transport efficiency, the detail that matters downstream is sulphuric acid byproduct, which has become a lever over the entire Copperbelt (see point 4). This processing depth is changing what the region can do with the rest of its supply chain.

3. A second export route is being built, and with it comes a second bidder.

The US- and EU-backed Lobito Corridor links the Copperbelt to Angola’s Atlantic coast, cutting transit from over a month to about a week, with $753m in DFC/DBSA financing closed and a greenfield Zambian extension underway.

But the travel-time saving is the obvious part. The structural part is that the route is explicitly Western-financed as an alternative to Chinese-controlled logistics. This gives host states more than one path to market, and more than one set of suitors for their ore. It also means the region now sits inside broader Sino-American dynamic, which brings capital and complications in the same package.

4. The two countries are learning they’re one system.

Zambia banned sulphuric acid exports in September 2025 to protect domestic supply (The ban has since been lifted). Because acid is the reagent DRC’s oxide-leach operations depend on, one country’s export policy became a direct input cost on the other’s production — spot acid reached $700/t in Kolwezi against a $150/t planning assumption.

The takeaway: The Copperbelt behaves as one industrial system even when its governments do not. A domestic intervention in Zambia can become an immediate production constraint in the DRC, making cross-border policy coordination (or its absence) a material copper-market variable.

5. The cobalt quota might be a broader mineral story in disguise.

The DRC replaced its cobalt export ban with a quota-and-royalty regime capping exports at 96,600 tonnes a year and is building a state stockpile through Gécamines. It’s reported as a cobalt event, but the more durable signal is the playbook: a resource state managing volume to manage price, tested on the metal where it holds more than 70% of global supply.

Copper is much less concentrated, making direct replication harder. But the broader precedent matters: Kinshasa is becoming more willing to manage mineral flows, renegotiate the state’s commercial role and use export policy to pursue price and domestic-processing objectives.

The next-decade.

Two developments that are drawing the most coverage will contribute little tonnage before 2029, which is worth touching on so they’re read for what they are — signals about the 2030s rather than the current supply wave.

Together, they suggest the region’s relevance isn’t a single-decade event: new geology, new capital, and new discovery methods are all extending it beyond today’s brownfield expansions.

The bird’s-eye view.

The Copperbelt’s near-term relevance comes from brownfield execution. Its longer-term relevance comes from becoming a more integrated industrial system — a system with local smelting, competing export routes and governments increasingly willing to intervene in flows. That integration raises the region’s supply potential, but it also means failures in power, acid, rail or policy can propagate across borders.

04 WHAT TO WATCH
 
Now → H2 2026: Ivanhoe’s updated Makoko/Western Forelands resource estimate, the step that turns a discovery into a defined project. Kamoa’s recovery from the 2025 seismic event that cut 2026 guidance to ~330kt; a clean ramp steadies the region’s flagship. And Zambia’s acid-export permitting, a recurring swing factor for DRC output.

2027–2029: The brownfield wave — Lumwana first copper, Kisanfu Phase 2 ramp, Kansanshi S3 achieving stated milestones. Also the Lobito Zambian extension holding its timeline would lift the region’s export ceiling.

2029 → the 2030s: The longer-run tests. Whether Mingomba proves a deep, capital-intensive build is executable, which would validate the model more broadly. And whether Makoko converts to a development decision. Together those help answer whether this decade’s brownfield surge is a peak or a starting point.

The common overhang is host-state policy: the same governments drawing the capital are rewriting the export and royalty rules, so regulatory risk is the variable to underwrite more than grade or geology.

/ Zambia’s Election Puts Copper Expansion Under the Microscope
Ahead of Zambia’s August election, investors are watching whether promised foreign investment can translate into actual mine output and whether chronic power constraints can be resolved. Zambia has the resources to expand materially, but electricity, financing and policy execution remain the real bottlenecks.

/ Higher Prices Cover for Lower Copper Output at Freeport
Freeport beat earnings expectations even as copper production fell 18.2%, with stronger prices offsetting the continued drag from Grasberg. A reminder that miner profits are recovering faster than mine supply.

/ Teck’s Copper Production Jumps as Quebrada Blanca Improves
Teck’s copper output rose nearly 25% helped by a stronger quarter at Quebrada Blanca. After a difficult ramp-up, QB is finally delivering the production growth expected from one of the few recent major mine builds.

That's the wire for today. The price is quiet; the ground underneath it isn't.
