Mining
Simandou has the potential to become the site of the largest integrated iron-ore mine and infrastructure project ever developed in Africa, consisting of a large new source of iron ore and creating a 650 km new railway to the Guinean coast at Matakong.
However, the potentially lucrative blocks I and II were mired for several years later in litigation of possible corruption. This corruption, which occurred through the use of bribery involved two Western foreign companies -
