Teck Said to Bid for Rio’s Iron Ore Co. of Canada Unit

Teck Resources Ltd., Canada’s second-biggest mining company, is among the remaining bidders for Rio Tinto Group’s controlling stake in Iron Ore Co. of Canada, according to a person familiar with the situation.

Rio may decide to keep its Iron Ore Co. stake after being disappointed with the bids it’s received so far, said the person, who asked not to be identified because the talks are private. While London-based Rio has considered selling the unit’s mining and infrastructure assets separately, it decided against the plan, the person said. Spokesmen for Teck and Rio and a spokeswoman for Iron Ore Co. declined to comment.
