CITIC ok’d to complete C$612m investment in Ivanhoe Mines

News that the Mongolian government is rethinking a 2009 deal that gave Ivanhoe Mines and Rio Tinto a 66% stake in the massive Oyu Tolgoi gold and copper project has sent the shares of Ivanhoe down more than 9.5% in Toronto on Wednesday afternoon, while Rio's ADRs gave up over 6% in New York trade. The bad news appears to have led to a bust-up between the two companies, with Ivanhoe founder and CEO Robert Friedland saying on Wednesday Rio's senior management has been making "unauthorized and incomplete" statements about Oyu Tolgoi and that he will take the matter up with the world's number three miner.

Adelaide Now reports BHP Billiton wants to "future-proof" its massive Olympic Dam project, including using driverless haulage trucks and this week put out a recruitment ad for an executive to oversee the high-tech initiative. The system would mean operators can be in a control room on the site or even in the comfort of a city office hundreds of kilometres away. BHP Billiton is in the final stages of the approval process for the $30 billion expansion of its existing underground operation at Olympic Dam to create a new open pit mine that would be the worlds biggest – trucks will haul overburden 24/7 for five to six years just to reach the ore body. The combined operations would mine 72 Mt ore per year and would produce 750,000 tonnes refined copper, 19,000 tonnes uranium oxide, 800,000 gold ounces and 2.9 Moz of silver per year.
