China Minmetals has announced that OZ Minerals shareholders have approved its sweetened A$1.7bn (US$1.39bn) asset acquisition deal.

"For our company, this is a landmark moment. This is a win-win transaction,” China Minmetals president Zhou Zhongshu said.
The assets acquired by Minmetals include Sepon, Golden Grove, Century, Rosebery, Avebury, Dugald River, High Lake, Izok Lake and OZ Minerals' interests in all other exploration and development assets.
