Guinea has officially commenced iron ore exports from the Simandou mines, a landmark development that marks the country’s entry into a new era of mineral exploitation. Simandou is home to the world’s largest untapped reserves of iron ore, and the project is expected to significantly boost Guinea’s economy, positioning the country as Africa’s second-largest mineral exporter after South Africa.
The $23 billion project incorporates a 650‑kilometre railway linking the mines in southeastern Guinea to two newly built ports on the Atlantic coast, enabling efficient mineral transport to international markets. Simandou is divided into four blocks managed by international companies. Blocks 1 and 2 are operated by Winning Consortium Simandou, backed by several Chinese firms, including China Baowu Steel Group, while Blocks 3 and 4 are controlled by Rio Tinto Plc in partnership with Aluminium Corp. of China (Chinalco).
At the ceremony marking the start of exports, Djiba Diakite, chief of staff at Guinea’s presidency, described the project as transformative for the nation. “Simandou must be for us what oil was for the Gulf countries,” he said. “The commissioning of the Simandou integrated mining and infrastructure project is a historic day for the people of Guinea, who have waited for this moment for decades.”
First explored in the 1950s during French colonial rule, the deposit’s high-grade potential was fully confirmed in the 1990s by Rio Tinto geologists. However, political instability, regulatory hurdles, and corporate disputes delayed development for decades, leaving the deposit largely dormant despite its global significance.
Experts anticipate that Simandou will reshape Guinea’s fiscal landscape. Mining currently accounts for roughly 2.2 percent of the nation’s GDP, but full-scale operation of Simandou could increase this contribution to around 3.4 percent between 2030 and 2039. Government revenues from the project are projected to reach $1 billion annually at peak production.
Beyond mining, Simandou represents a major infrastructure initiative. Its railway and port facilities are designed to streamline ore transportation, enhance logistical efficiency, and support broader economic development. Analysts suggest that successful commissioning could attract further foreign investment, not only into iron ore production but also into Guinea’s wider mining sector, potentially creating jobs and stimulating ancillary industries.
The project is expected to strengthen Guinea’s position in global mineral markets, particularly in supplying high-grade iron ore to major steel producers. Observers note that the combination of significant mineral reserves and modern infrastructure could make Guinea a critical player in the international mining industry over the next decade.
