Milbank, Tweed, Hadley & McCloy and Morrison & Foerster have advised on a $1.4 billion financing for a Japanese government-backed project to source copper concentrate in Chile.

Morrison & Foerster Tokyo partners Dale Caldwell and Mike Graffagna represented Minera Lumina Copper Chile, a joint venture between two Japanese metals companies, Mitsui Mining & Smelting Co. Ltd. and JX Holdings, Inc. The JV is developing a mine in Chile that is expected to begin production in 2013. The site is expected to eventually meet 11 percent of Japan’s annual demand for copper concentrate.
