For decades, the Simandou iron ore project has been a hot spot for Guinea to seek investment. It is reported that the railway construction and tunnel construction of the Simandou iron ore project in southeastern Guinea in Africa has started. The Simandou deposit is estimated to be 2.4 billion tons of high-grade ore. The mine is located in West Africa and will reshape the global iron ore trade pattern.

The investment in the Simandou iron ore project is estimated to be as high as 20 billion U.S. dollars; the government of Guinea, like Rio Tinto, Chinalco, and IFC, also holds shares in the project; in addition to iron ore development, the project also includes two major foundations: railway and seaport Facility construction, and an investment consortium should be formed "within the agreed time frame".

The infrastructure project will build a 650-kilometer railway line and a deep-water port in Matakong on the Atlantic coast, aiming to put these two blocks (blocks 1 and 2) into production by 2025 to provide shipping facilities. The railway will pass through an 11.7-kilometer tunnel through the mountain. A second tunnel with a total length of 9 km will also be constructed in Ouré-Kaba County in Mamou County. According to the Ministry of Mines of Guinea, the tunnel construction will take three years and is expected to be completed by January 2024. Editor/Xu Shengpeng
