...McArthur River isn't much to look at from above ground--just a cluster of green, corrugated-metal buildings, a company lodge and an airstrip--but the mine is an industrial marvel. The rocks underground average 21% pure uranium, with pockets as concentrated as 80%, far richer than the typical 1% deposits at other mines. The ore at McArthur River is the richest in the world and is far too radioactive to handle conventionally; the miners extract it by remote control, using giant boring machines and scoop trams instead of pickaxes and shovels...
Since uranium was discovered at McArthur River in 1988, its corporate owner, Cameco, based in Saskatoon, Sask., has spent $277 million to develop it. Considering that the price of uranium has languished below the cost of production for most of the intervening years, Cameco's investment might seem like a fool's wager--until you look at what is happening in the battered market for U3O8, the raw uranium that's refined and enriched for use in nuclear reactors...
Even as the debate over long-term storage of spent nuclear fuel raged during the 1990s, U.S. uranium consumption rose about 35% over the decade, to about 55 million lbs. in 2001. That makes Cameco's bet on McArthur River--and the firm's nearby mine, Cigar Lake, which could begin production around mid-decade--look a lot less foolish...
...recent winter day, more than 2,000 ft. below the surface of the McArthur River mine, Dale Powder operated a scoop tram from a niche in the rock wall 100 ft. or so from the vehicle. He wore a hard hat and rubber boots, a radiation detector and a shoulder harness with a pair of joysticks that he manipulated through his heavy work gloves. The scoop tram looked like a dump truck with the cab lopped off. On solid-rubber tires 5 ft. high, it carried freshly mined ore in soccer-ball-size chunks to the "grizzly," the big grated...
Powder is from Uranium City, 186 miles northwest of the mine, and near the end of his day shift, he was one of only two dozen or so miners at work underground at McArthur River. Where Powder works, it's as dry as a bone, but a few hundred feet away, in a neighboring tunnel, a perpetual fine rain falls. The porous sandstone that encases the mine's ore zone is saturated, even in winter, with water melting from the frozen surface. To keep the water from pouring into the mining shafts, Cameco's engineers have pulled off a remarkable...
