Guinea’s Simandou iron ore project has sharply increased exports in its early production phase, shipping a record 2.2 million tonnes in May as operations accelerate following decades of development delays.
The figure, reported on Wednesday, marks a significant rise from an average of about 600,000 tonnes per month during the first quarter of 2026, highlighting the rapid scaling-up of one of the world’s largest untapped iron ore deposits.
Simandou began production in November 2025 after more than 20 years of preparation, with its first export shipments dispatched in January 2026. The project is now moving through a ramp-up phase as mining, rail and port infrastructure progressively expand capacity.
The May shipment total surpassed the previous monthly high of 1.3 million tonnes recorded in April, underscoring improving operational efficiency across the supply chain, particularly at the Morebaya port facility used for exports.
The Simandou complex is being developed by the Rio Tinto Simfer joint venture and the Winning Consortium Simandou partnership, which together are responsible for four mining blocks with a combined planned production capacity of 120 million tonnes per year.

Industry observers say the recent increase in exports reflects gradual improvements in rail transport coordination and port loading systems as infrastructure continues to come online.
Alexandre Claude, chief executive of DBX Commodities, said early-year expectations had pointed to a slower ramp-up due to logistical constraints, particularly in rail transportation.
“At the beginning of the year, we expected a slow and constrained first half because of railway transportation challenges,” he said, adding that May’s figures suggest improved loading rates at the export terminal.
For Guinea, Simandou represents the cornerstone of its long-term economic transformation strategy and one of the most significant mining developments in Africa.
The government plans to use future revenues from the project to finance infrastructure development, expand agricultural production, strengthen education systems and support broader industrialisation efforts.
Officials have positioned the project as central to the country’s Simandou 2040 development agenda, which seeks to diversify the economy beyond raw mineral exports and integrate mining with wider industrial growth.
The project is also strategically important for global commodity markets. China, which is heavily involved in the development of Simandou, currently imports around 80 percent of its iron ore from Australia and Brazil, making the Guinean project a potential diversification source.
Chinese investors view Simandou as a key long-term supply asset aimed at reducing concentration risk in global iron ore supply chains.
Despite the strong early momentum, analysts caution that the project remains in its commissioning phase and will need sustained logistical performance to reach its full annual capacity target.

The continued expansion of rail and port infrastructure will be critical to achieving steady output increases toward the planned 120 million tonnes per year.
Guinean authorities have said maintaining this trajectory is essential not only for export revenues but also for delivering on the project’s broader promise of economic transformation.
If successful, Simandou could become one of the largest iron ore mining operations in the world, reshaping Guinea’s role in global commodity markets while providing a major source of funding for national development priorities.
