Posco, Asia’s third-largest steelmaker, agreed to buy a stake in ArcelorMittal Mines Canada Inc, Chung Jae Woong, a Seoul-based spokesman at Posco said.

The Korean steelmaker hasn’t decided on the amount of stake it will purchase or for how much, Chung said on Tuesday. The Maeil Business Newspaper reported earlier on Tuesday Posco will buy a 15 per cent stake in the mine for $1.1 billion. Yonhap News reported a group, including Posco and China Steel Corp, will buy the stake for $1.1 billion. China Steel will invest $540 million, while Posco will spend $270 million, the Korean-language news agency said, citing people it didn’t identify.
