BMI View: With vast gold and coal reserves, Tanzania has the potential to become one of the leading mining centre in Sub-Saharan Africa. However, the country's unfavourable operating environment is a major impediment to the development of the local mining industry. We highlight a fragile investment climate, in which foreign-owned mining operators have been subjected to growing restrictions and financial charges, most notably in the case of a long-running dispute between the government and Barrick Gold subsidiary, Acacia Mining. As in other parts of Africa, the trend towards resource nationalism will be of increasing concern to overseas investors. Meanwhile, long-running constraints, including the poor development of transport and other critical infrastructure, present further challenges to growth.
