A Canadian company’s push to build the United States’ first new conventional uranium mill since the Cold War has cleared local hurdles — despite environmental concerns — and won wary high-level support. Many residents of the economically bereft western Colorado area around Nucla and Naturita (approximate population 700 each) now count on the Energy Fuels Inc. project to bring back Atomic Age prosperity. Beyond the mill, they envision uranium mining jobs as part of a national nuclear renaissance that could spur homebuilding, better schools, restaurants and recreational amenities. “Nothing’s going to happen without a mill,” said Mike Thompson, 25, board member of the Naturita-based Western Small Miners Association. “Right now, we can’t support 18- to 30-year-olds because we just don’t have the jobs.”
