ArcelorMittal Liberia's Phase II expansion is the most consequential industrial project in Liberia and one of the more strategically revealing ore investments in West Africa. The headline numbers are 20 Mt/y of exports by 2027 versus under 5 Mt in 2024, a $1.8 billion program covering a concentrator, rail, port and two power plants, and cumulative Liberia investment now "approaching $4 billion." The reason to pay attention is less about tonnage than about what kind of product the concentrator makes and who wants it.
What is actually being built
The $1.8 billion programme comprises four components: Liberia's first large-scale iron ore concentrator, rehabilitation and capacity expansion of the government-owned Tokadeh–Buchanan railway, upgrades at Buchanan Port, and two captive power plants. Roughly $800 million of the group's Liberia spend has gone to the rail and port infrastructure, which the government owns, not ArcelorMittal.
The concentrator is the strategic component. It is designed to produce a premium concentrate, and ArcelorMittal Liberia has explicitly positioned that product toward international steelmakers, including newer plants deploying low-carbon and carbon-reducing technologies. That framing matters: DR-grade and high-grade concentrate is scarce, and European and MENA direct-reduction projects are chasing it.
| Metric | Value |
|---|---|
| Phase II capex programme | ~$1.8bn |
| Cumulative Liberia investment (Jan 2026) | $3.5bn |
| Cumulative Liberia investment (Oct 2026, stated) | "approaching $4bn" |
| Rail/port spend (government-owned assets) | ~$800m |
| Exports 2024 | <5 Mt |
| Exports targeted 2027 | >20 Mt |
| Longer-term mine production ambition | 30 Mt/y |
| MDA term | To 2050, renewable +25 years |
The investment arithmetic is murkier than the headline
The cumulative figure and the programme figure are not the same thing, and the reporting tends to blur them. The ~$4 billion spans everything since ArcelorMittal restarted Liberian mining in 2011: Phase I operations, the $800m rail/port works, power, and social infrastructure. The $1.8 billion is the Phase II programme specifically. Between January and October 2026 the cumulative number appears to have risen by roughly $500 million, which is plausibly Phase II construction spend, but that is inference rather than a stated breakdown.
For suppliers this distinction is practical rather than academic: a cumulative number tells you little about how much Phase II money is still to be committed, and when.
Rail access is the real commercial variable
The Tokadeh–Buchanan line is state-owned, and the government decides who runs on it. CEO Michiel van der Merwe has said on the record that ArcelorMittal supports multiple users. Third parties wanting access would be expected to fund the incremental capacity their operations require, though spare capacity exists in the meantime. An independent operator is expected to run the railway from 2030, with operating principles "currently being formalized."
The "spare capacity in the meantime" wording is the interesting part. It implies Phase II capacity is being sized above ArcelorMittal's own near-term needs, which in turn implies latent rail and port headroom for other Liberian and Guinean shippers, and a possible future revenue line for a third-party operator. Treat the 2030 multi-user regime as a stated intent, not a contract: no operator has been named, and no third-party tonnage has been contracted publicly.
Where the steel sits
Phase II is a genuine steel-intensive build, though the procurement picture is opaque. The concentrator requires structural steel, plate and large volumes of process equipment; the rail works need rail, fastenings and bridge/culvert steel; the port upgrades need berth and materials-handling structures; and the power plants need structural and boiler/piping steel.
What is not available in public evidence is anything like the detail needed to size that: no EPC or EPCM contractor has been identified, no concentrator technology supplier has been named, and no tonnages or grades disclosed. The historical context is a caution against assuming reuse: the original LAMCO-era pelletising plant at Buchanan, Africa's first when it opened in 1968, was wrecked in the civil war and reportedly sold for scrap in 2010. There is no legacy processing steel to repurpose. Everything is new-build.
Procurement status should therefore be described plainly: not verified as awarded, and not verified as open. The safe read is that an expansion of this scale, mid-construction with commissioning targeted for 2027, will still require substantial fabricated and structural steel supply and erection services over the coming quarters, but anyone treating these packages as confirmed opportunities is working from assumption, not evidence.
What to watch
The near-term signals that would resolve most of the open questions are contractor awards: an EPC or EPCM for the concentrator, a rail rehabilitation package, a port package, and power plant contracts. Any of these would clarify scope, timing and steel specifications at once. Alongside that, watch for the naming of the independent railway operator and the first evidence of a third-party access agreement, which would tell you whether Liberia's rail corridor is genuinely becoming multi-user or remaining a single-shipper asset in practice.
The concentrator's product slate is the other thing worth tracking. If Phase II concentrate is directed at direct-reduction steelmaking rather than blast furnace burden, the project's strategic weight is considerably higher than 20 Mt/y of exports would otherwise suggest.
