An Australian coal company is withdrawing its plan for a mine in the Crowsnest Pass region of the eastern slopes of Alberta's Rocky Mountains. "The coal mine, in our minds, is a no-go," said Peter Doyle, CEO of Montem Resources, which had proposed to redevelop the Tent Mountain site to produce steelmaking coal. In a letter filed Tuesday, Montem Resources asked the Alberta Energy Regulator to end the environmental impact assessment for the proposal.
