This is particularly worrying, as in the minds of some investors it is linked with proposals over the past 12 months for new mining codes in Guinea, Democratic Republic of Congo and Zimbabwe, and new mining taxes in Côte d’Ivoire, Ghana and Zambia.

At an Indaba panel discussion, Sheila Khama, a mining expert at ACET, a multilateral-sponsored think-tank, says government equity participation in joint ventures can sometimes help states understand what drives investment.
