The Simandou project is a large, high-quality open-pit iron ore mining project located in the Kérouané province in southeastern Guinea, West Africa. It has proven resources of over 4 billion tons, with an average total iron grade of over 65%. The project is divided into two blocks, north and south, and is jointly developed by the Guinean government, the SimFer joint venture (comprising Rio Tinto and Chinalco Iron & Steel, among others), and the Winning Alliance (including Weli International, Weiqiao Aluminum, Baowu Resources, etc.), with the Guinean government holding a 15% stake. The project covers systemic infrastructure like mines, railways, and ports, and requires constructing a cross-Guinea railway of about 600 kilometers to connect the mines to the port of Matakong.
