ArcelorMittal S.A. : ArcelorMittal completes the first instalment of its sale
 of a 15% interest in ArcelorMittal Mines Canada for $1.1bln to a Consortium
                   led by POSCO and China Steel Corporation

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.

As part of its strategy to  build strategic relationships with key  customers, 
the joint venture has also entered into long-term iron ore off-take agreements
with POSCO and CSC proportionate to the consortium's joint venture interests.

The second instalment of the investment by the consortium, which will increase
the consortium's interest  in the  joint venture  to 15%,  remains subject  to 
various conditions and is expected to close in the second quarter of 2013.
