Global miner Anglo American has risked its future in the world's largest copper producing nation by denying Chile's state-owned Codelco a 49 percent stake in its Sur unit, said Diego Hernandez, Codelco's chief executive on Thursday. Miguel Angel Durán, president of Anglo American’s Chilean operations, told a Chilean newspaper that the company wants to sit down with Codelco, the Chilean state mining company, and find a way to avoid years of litigation over Anglo’s Chilean assets. The copper giant is putting together a crack team of lawyers and financial advisers from Chile and New York to fight Anglo’s attempt to block it from exercising an option to buy half of Anglo’s Chilean copper assets for $6 billion. Anglo early in November sold 24.5% to Mitsubishi for $5.4 billion.

A major expansion to an existing coal mining operation near historic Bryce Canyon National Park is getting a frosty reception in tourism-friendly Utah, reports Steel Guru. Alton Coal Development LLC and partner Kane Mining want to expand their reserves at the Coal Hollow Mine — Utah's only coal strip-mine — just one year after the mine opened. The expansion to more than 3500 acres requires the approval of the US Bureau of Land Management. But opponents are already lining up against the proposal, with one online petition signed by over 21,000 people.

Wind turbine manufacturers are scrambling to find alternatives to a key element used in direct-drive permanent magnet generators (PMGs), thanks to skyrocketing prices and diminishing supplies of crucial rare earths. China currently provides 94% of the world's rare earths, including neodymium and dysprosium, which are used in the magnets for direct-drive wind turbine motors. However, the Chinese government has put new restrictions on rare-earth mining that have resulted in lower supply levels, according to a report from research firm Roskill Information Services (RIS).

The International Energy agency says in its World Energy Outlook 2011 released last week, widespread deployment of more efficient coal-fired power plants and carbon capture and storage (CCS) technology could boost the long-term prospects for coal, but there are still considerable hurdles. The agency says more efficient technology for new coal power plants would require relatively small additional investments, but improving efficiency levels at existing plants would come at a much higher cost. The IEA says If CCS is not widely deployed in the 2020s, an "extraordinary burden" would rest on other low-carbon technologies to deliver lower emissions in line with global climate objectives. Today only two small pilot projects in Germany and the US exist and a $4.8 billion project in the UK, which would be the world's largest appears to be going nowhere.
