Luxembourg, 15 March 2013 - ArcelorMittal announces today the completion of the first instalment of the previously announced investment by a consortium led by POSCO and China Steel Corporation (CSC) to acquire a joint venture interest in ArcelorMittal's Labrador Trough iron ore mining and infrastructure assets in Quebec, Canada.

The consortium acquired an 11.05% interest in the joint venture for total consideration of US$810 million in cash, with ArcelorMittal's wholly owned subsidiary ArcelorMittal Mines Canada retaining an 88.95% interest in the joint venture.
