Cameco Corp. plans to begin output at the world’s largest untapped uranium deposit in 2013, just in time to make up for a shortfall in global supplies. The project’s critics say it won’t happen.

The Canadian company, the world’s second-largest uranium producer, is developing the Cigar Lake mine in Saskatchewan beneath almost a half-kilometer (1,641 feet) of water-soaked sandstone. The mine, six years behind schedule because of floods, could meet 10 percent of current global needs.
