Alaska's Pebble deposit presents big problems for Northern Dynasty, the junior Canadian miner that wants to cash out of its sole asset. Pebble has an eye-popping recoverable resource of 67 million ounces of gold and 55 billion pounds copper with some molybdenum thrown in for good measure which at today's prices is worth over $300 billion in total. The Vancouver company shares the venture with Anglo-American but the $4.7 billion development costs could be too rich even for the London-listed giant's blood. Apart from the problem of finding a heavyweight buyer for its 50%, Dynasty also faces opposition from a $150 million a year salmon fishery near the site and local environmental protesters who have enlisted the support of Hollywood celebrities like Robert Redford.

Reuters reports Indonesia may impose a tax or quota on mineral ore exports ahead of a planned regulation to ban all exports of raw minerals by 2014, the industry ministry said on Wednesday. The planned ban is part of a mining and coal law introduced in 2009 that requires miners to process minerals into higher value products before exporting them. The move would negatively impact copper miners Newmont and Freeport as currently only 30% of output is processed domestically and comes on top of news that workers at Freeport's massive Grasberg mine in the Papua province plan a second strike next week after wages negotiations broke down.

The deal-making frenzy in the global mining sector during the first half of the year was followed by a dramatic drop in activity in July and August, according to a new report by consultants PricewaterhouseCoopers. Figures from the report titled Riders on the Storm show that in July and August the value of global mining deals fell by 49% and deal volumes declined by 25%. The sharp reversal came after a record first half when 1,379 deals worth $71bn were announced even though Chinese entities, firmly focused on value, retreated from iconic western takeovers. Buyers were also willing to pay over the odds for large publicly listed targets – for $500 million+ acquisitions, the average premium was 37%. For sub-$500 million deals, premiums averaged a mere 8%.
