Cynthia Carroll, chief executive of Anglo American, speaks as she sits next to the name plate for Tokyo Sexwale, executive chairman of Mvelaphanda Holdings, at the opening session of the World Economic Forum (WEF) in Cape Town, South Africa, June 13, 2007. Anglo American Plc, the world's third biggest mining group, plans to inject $3.5 billion of new investment into Africa over the next five years, its chief executive said on Wednesday. Carroll said her firm would pump the money into several exploration and mining projects across the continent, which she said is seeing strong growth and reduced political risk.
