Korea’s LG International is ponying up US$176 million for a 20 percent stake in Augusta Resource’s (AMEX: AZC ) Rosemont copper and molybdenum project. The group is also going to buy 30 percent of the copper concentrate and 20 percent of the copper cathode and molybdenum produced for the mine. This month, Japan’s Sumitomo Corp. and Sumitomo Metal Mining Co. jointly bought a 45 percent stake in Quadra FNX Mining’s (TSE: QUX ) Sierra Gorda copper in Chile for US$1.2 billion. (Quadra FNX is itself the result of the largest copper merger in 2010 between Quadra Mining and FNX Mining.) And Singapore’s Tamsek signed a US$510 million deal with Inmet, which will go to developing Inmet’s gold and copper project in Panama (which was the center of attacks from Equinox during the Lundin-Inmet merger talks that eventually fell apart).
