Waste has just stopped leaking from Mount Polley mine

Reuters reports Zambia has lifted a ban on metal exports just two days after imposing it to sort out revenue collection and increase transparency in Africa's top copper producer, a minerals ministry official said on Thursday. 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.

Even if both Keystone XL and Enbridge's Northern Gateway pipelines are built, bitumen is expensive to extract and cannot compete with the many new shale oil plays – particularly in the Bakken oil basin where studies put the recoverable oil at 24 billion barrels – which have pushed US production to its highest level in a decade. No wonder Enbridge – busy building out its capacity in Bakken while Northern Gateway wallows in the approval process – said "it's the wild west out there at the moment."

The Keystone XL pipeline project of TransCanada Corp. should be halted because the US did not complete an environmental impact review before work started, green advocacy groups said in a lawsuit filed on Wednesday. The Center for Biological Diversity, Friends of the Earth and Western Nebraska Resources Council alleges the public process was a "sham" and that TransCanada has already started construction in the lawsuit filed in Omaha, Nebraska federal court. Governors of five of the six states the pipeline crosses have backed the project, except for the Nebraska. TransCanada has strongly denied the claims – all it did in Nebraska was "mow some grass."
