Shares in London-listed Antofagasta, the copper giant controlled by Chile’s Luksic family, jumped 7% in afternoon trade on the FTSE, one of the best performers on a good day for miners. CEO Marcelo Awad earlier told Dow Jones Newswires the slump in copper prices in the last few weeks is a market overreaction and it hadn't seen any of its customers cancel or delay shipments. Copper has slumped over 30% since peaking at an all-time high of $10,190/tonne in February and Awad added that European customers of Antofagasta – after Thursday's move upward worth £10 billion again – are nevertheless reluctant to commit to 2012 orders thanks to all the uncertainty in the eurozone. The Luksics could do with a bit of a boost: analysts say Chile's richest family may have lost their way after buying control of Latin America’s largest container shipping company last month.

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.

Despite worldwide efforts to reduce the consumption of rare earth elements, researcher IMARC Group expects strategies like substitution and recycling to have a little effect on demand for erbium, dysprosium, terbium, neodymium and europium in the short term.

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."

Gold and gold receivables held by euro zone central banks rose by €56.8 billion to €420 billion after a quarterly revaluation, the European Central Bank said on Wednesday. Net foreign exchange reserves in the Eurosystem of central banks rose by €13.2 billion to €191.1 billion after the revaluation, the ECB said in a weekly consolidated financial statement. The combined balance sheet of the ECB and the 17 national euro zone central banks grew by €80.8 billion to €2.289 trillion, the statement showed. The euro fell against the dollar on Wednesday as worries about a Greek default persist and one day after the first European bank had to be bailed out.

Canada's North American Palladium said it plans to expand its flagship mine in Northern Ontario at a cost of around $75 million for the first phase of the project. Phase 1 of the Lac des Iles expansion should be completed in the fourth quarter of next year when the shaft will begin operating at a rate of 3,500 tonnes per day. The mine is located northwest of the city of Thunder Bay, and its primary deposits are palladium with some platinum, gold, nickel, and copper by-products. The company, which also operates two gold mines in Quebec, received a bump at the opening of trade in New York with the stock up 3.3% in a softer broader market.

Businessweek reports on the day it cleared and matched its first gold trade the London Metal Exchange which handles some 80% of global trade in metals futures, told members on Tuesday that it has receive "many" expressions of interest from potential bidders. The 134-year-old exchange is facing increased competition from other exchanges in Asia and is plagued by a backlog of industrial metals particularly aluminum that’s building at warehouses. LME-monitored warehouses contain 6.7 million metric tons of metal and at some warehouses such as Detroit it can take as long as seven months to withdraw metal. The LME is looking to start trading silver next year.

US stocks were driven down at Tuesday’s start with the Dow Jones falling as much as 250 points as Belgium's Dexia become the first Eurozone bank to be bailed out before making a dramatic about turn during the last hour of trade to end up 153 points or 1.4%. The S&P 500 dropped shortly after the opening bell only to end up 2.25% at 1,124 points, but is still down 18% over the last four months. The resource-heavy TSX composite index were almost at a two-year low before making up some of the lost ground to end down just two-thirds of a percent. Gold could not capitalize on the ongoing volatility and fell further after hours to trade at $1,623/oz. Bullion had briefly dipped below $1,600/oz before noon.

The Independent reports the first coal to be mined in Newcastle upon Tyne for more than 50 years could be dug on the site of a 21st century science park ahead of construction. Up to 60,000 tonnes of coal lie below what was a brewery until recently. The area was mined extensively in the 18th century and the various workings underneath make present-day building work perilous.
