Mr. Chairman, it's a difficult question to answer. I can risk an answer.
The major concern we hear about rare earth mines is associated with radioactivity, mainly thorium. It's sometimes uranium, but most of the time it's thorium. Thorium is less nasty and less radioactive than uranium.
So far, the data we have indicate that most Canadian deposits do not have high concentrations of radioactivity. They are at levels that need to be managed in any case, and the environmental assessment process normally helps to identify what's in the deposit and how to manage it. It's the company that will have to develop a plan to be able to do that.
