Is the African mining sector becoming uninvestable?

(How We Made It In Africa) - At the recent Africa Forum hosted by Hogan Lovells, in London, a number of common, positive themes came through: Africa is a continent of endless possibilities and opportunities; Africa has significant natural and human resources which can be unlocked for the benefit of all Africans; and the investability of many African countries has improved, for various reasons, including mature banking, finance and legal institutions, investment-friendly policies and regulatory frameworks, and national development plans which demonstrate governmental support for sustainable infrastructure and development.
