Zambia: Mines audit planned

Top African copper producer Zambia plans to audit all its mining houses in a bid to dig for back taxes of up to $1 billion it estimates it is owed, its mines minister said. Such a policy by the government of populist president Michael Sata would widen an initiative launched by the previous administration and comes against the backdrop of a surge of resource nationalism across Africa and Zambia's own doubling of copper royalties to six per cent.
