* Says offer yet to be discussed by Baffinland board
* Says will vote against board support of proposed bid
TORONTO, Jan 14 (Reuters) - ArcelorMittal
ArcelorMittal, the world's largest steelmaker, and Nunavut Iron, backed by U.S. private equity, on Friday made a C$1.50-a-share offer for 100 percent of Baffinland. Their joint bid may have ended a four-month fight to control its huge iron ore deposit in the Canadian Arctic.
Baffinland Chairman Richard McCloskey, who is also acting chief executive, said he planned vote against board support of the proposed bid. (Reporting by Pav Jordan; Writing by Euan Rocha; Editing by Frank McGurty)
