Chile will draw on all options at its disposal, including suing for damages, to defend the interests of state-owned Codelco in its fight with Anglo American, President Sebastián Piñera told the Asia Pacific Economic Cooperation Forum on Saturday. Earlier Codelco's chief Diego Hernandez said in a press interview the looming legal battle with Anglo could take three to four years to be resolved. The state-owned 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 last week sold 24.5% to Mitsubishi for $5.4 billion.

The Telegraph reports Anglo American CEO Cynthia Carroll took a last-minute flight to Santiago on Thursday to calm tempers over the sale of a 24.5% stake to Mitsubishi Corporation but neither Chile's president Sebastian Pinera, finance minister Felipe Larrain or mining minister Hernan de Solminihac would see her. She is understood to have contacted all three before announcing the $5.39 billion deal that undermines state-owned copper giant Codelco's plan to exercise the 33-year old option to buy half of Anglo's Sur copper complex. The Mitsubishi transaction values Anglo Sur at $22 billion and Anglo's stock is up 4.8% since the deal. Codelco was offering $6 billion for 50% and is now putting together a team of top New York and Chile litigation firms and financial advisor Rothchild.

Katanga Mining announced on Friday it has secured $635.5 million in new loan facilities from parent Glencore International to fund the expansion of its Democratic Republic of Congo copper-cobalt mine. The Toronto-listed firm wants to bump copper production to 270,000 tonnes per annum and thereafter bump it up to 310,000 tonnes from cash flow. The company is already ramping up copper production with financials results also out on Friday showing year to date copper in ore mined was 157,658 tonnes, a 96% increase over 2010. Cobalt produced fell 30% to 593 tonnes, but that was in line with expectations.

While peace in Afghanistan still looks to be a utopian dream, AFP reports that developing nations like China and India are eager to make resource deals in the troubled country even before the guns fall silent: While an end to the fighting seems remote for now, mining lots are being quickly parcelled out among Afghanistan's resource-hungry neighbours, potentially sparking a new "Great Game" for control of its battle-worn ground. According to mining ministry documents seen by AFP, Afghanistan is planning to sell extraction rights for up to five mines every year until the departure of the last foreign combat troops in 2014 -- a rattling pace, say experts.
