It's good news for the Zambian mining sector – a lengthy suspension could have further pressured mines already dealing with volatile metal prices in recent weeks. Newly elected President Michael Sata has been concerned – analysts say with good reason – about copper exporters misreporting the amount of ore leaving Zambia, and earlier this week suspended export permits, to put new guidelines in place. Cobalt, gold and nickel also fell under the ban and now all export payments need to be routed via the central bank.
