Cigar Lake

The highest-grade large uranium mine in the world.

What this place is

The ore is so radioactive and the ground so waterlogged that Cameco freezes the rock solid and cuts it with a remote water jet. No one stands at the face.

Grade. Ore grades around a hundred times the world average, high enough that the ore is handled remotely.
“Grade” is the percentage of the useful stuff in the rock. A copper mine at 0.5% grade throws away 199 tonnes of rock for every tonne of copper it sells. That single number decides whether an orebody is a mine or just an interesting piece of geology.

What comes out

A “by-product” is a metal recovered because it happens to be in the same rock, not because anyone went looking for it. Its supply therefore follows the primary metal’s economics, not its own.
