Thank you, Mr. Chair.
First of all, thorium is not an issue for all Canadian development. Thorium is not an element that shows up necessarily with every single rare earth mineral deposit. It occurs with some, not with others.
I am personally not aware of any systematic research that has been done to address the thorium stability issue in tailings. This is something that definitely has to be part of the research priorities.
But in Canada, we have a lot of experience from the uranium mining in Saskatchewan, and dealing with the radioactive tailings. Again, I am not an expert in this area, but I would say in Saskatchewan the management of the uranium tailings should meet the environmental requirement.
