In May 2011 Jinchuan Group, one of China's largest nickel and copper producers (Gansu Province, state-owned), agreed to acquire South African mining company Metorex Limited for ZAR 9.1 billion (approximately USD 1.36 billion), besting a competing bid from Vale. Metorex's principal asset was a 77% stake in Kinsenda Copper Company (DRC), operator of the Kinsenda underground copper mine in Katanga Province — at the time one of the world's highest-grade active underground copper mines, with ore grades of approximately 5.5% copper. The acquisition gave Jinchuan effective control of Kinsenda, adding high-grade DRC copper production to its existing Chinese and African operations. It was one of the first Chinese state-enterprise acquisitions of a JSE-listed mining company and established a template for Chinese SOE outbidding of Western and emerging-market competitors for African copper assets. The deal was financed by state-directed credit from China Development Bank and represents one of approximately 14 high-value mining transactions (each >$100M) in which Chinese policy-bank lending was deployed to secure copper and cobalt assets in the DRC-Zambia copper belt in the 2010-2015 period.
