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...
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...
Here's how it works: McArthur River uses two horizontal floors, above and below the uranium-ore zone. One floor is 1,740 ft. underground and the other is at 2,100 ft., where Powder was stationed on the day of our visit. To start mining a new section of ore, a drill is used to dig a 15-in. pilot hole from the upper level to the lower one. Once the drill bit punches through the ceiling of the lower horizontal shaft, the drill is removed and a 10-ton, 10-ft.-wide reamer with tungsten-carbide teeth...

...Some of the stuff Missy Elliott’s done in the past few years is more innovative that most of the underground hip-hop I’ve heard,” he says. “Yet there’s stuff in the mainstream which I think is also devoid of…of anything. Like Ja Rule, DMX…it’s just...
