Junior miners remain in focus after Atlas Iron sought a trading halt on Tuesday. "The news from Atlas Iron was something I have long suggested was coming and I don't believe it will be the last bad news on the wires. I have concerns for BC Iron, Mount Gibson and the junior play Gindalbie Metals," Evan Lucas, IG's market strategist, wrote in a note.
Shares of BC Iron and Gindalbie Metals tanked nearly 10 percent each, while Mount Gibson erased gains to close virtually unchanged.
