Guinea's Morebaya port shipped 2.2 million tonnes of Simandou iron ore in May, up from a record 1.3 million tonnes in April and no more than 0.6 million tonnes in any of the first three months of the year, according to Bloomberg reporting carried by Mining Weekly on June 3.
For the Capesize market, this is the moment a long-promised project became a demand line on the map. Simandou is the first structural addition to iron ore tonne-mile demand since Vale ramped up its Brazilian exports, and geography does the heavy lifting: the run from Morebaya to China is roughly double the Pilbara-to-China distance, so every tonne shipped out of Guinea absorbs about twice the vessel-days of an Australian tonne. That multiplier is why a project still shipping single-digit millions of tonnes a year already has the attention of every Capesize desk.
From first ore to 120 million tonnes
The ramp has been quick by mining standards. The first ore sailed on December 2 2025 aboard Winning Youth and reached Majishan, in China's Zhejiang province, on January 17 2026. That maiden voyage made the tonne-mile point by itself: a cargo that left West Africa in the first days of December was still at sea deep into January. The project spans four blocks, with the Baowu-backed Winning consortium on blocks 1 and 2 and Simfer, the Rio Tinto and Chinalco venture, on blocks 3 and 4. Nameplate capacity is 120 million tonnes a year on a ramp of roughly 30 months: around 5 to 10 million tonnes in 2026, rising to 60 million and then the full 120 million. Brokerage Ifchor Galbraiths projects shipments of up to 8 million tonnes in the third quarter and 12 million in the fourth.
Twice the distance, twice the work
Distance is what turns a mid-sized export stream into a large freight event. BRS puts the combined Brazil-plus-Guinea fronthaul about 58% above the Australia-to-China run, and every Simandou cargo stretches that gap further. The destination side is just as lopsided: DBX's Alexandre Claude noted in the Bloomberg report that the great bulk of this year's Guinean flows have gone to China. The pull shows in the import data, with China's iron ore imports up 8% year on year at 418.6 million tonnes over January to April. Concentrating the new cargoes on China means concentrating them on one of the longest hauls in the iron ore trade, which is exactly where tonne-mile demand is created fastest. It also concentrates risk, since a single buyer sits at the end of the longest supply line.
Supplement or displace
Whether the freight math stays bullish turns on a single question: does Simandou ore supplement Australian and Brazilian supply, or displace it? If Chinese mills take Guinean tonnes on top of existing flows, tonne-mile demand compounds and the Capesize balance tightens for years. If Simandou instead squeezes out cargoes from shorter hauls, the net gain shrinks, though the distance asymmetry means even a displaced Australian tonne is replaced by one that works a ship twice as hard. Breakwave Advisors flagged mounting price pressure in a June 5 insight, a reminder that 120 million tonnes a year of new supply must find its place in a market that will not simply absorb it at prevailing prices.
The road ahead
The ramp is not riskless. A fatality at the Simfer operation in February, strike action at BWCS in May and a rainy season that runs from May to October are all reminders that this is a frontier logistics chain being pushed hard. Those are also the ingredients of freight volatility, and BRS analyst Wilson Wirawan expects the new trade to feed demand for FFA hedging alongside it. "Capesize freight prospects are poised for renewed strength heading into 2026 and beyond," Wirawan told Riviera as the first cargoes moved. The near-term test is concrete: hold the ramp through the rains and deliver on Ifchor Galbraiths' 8 million tonne third quarter. If Morebaya does that, the Capesize map will have gained a durable third pole alongside Australia and Brazil, and the market's freight arithmetic will have changed for good.
