Just to answer that, again, the mines are only about 20% of the area, but the challenge with the mines is that they produce for a long, long period of time, in the range of 40 years. This is a challenge, so reclamation is an issue.
That said, of the 530 square kilometres that have been disturbed so far, about 65 square kilometres are under active reclamation. The fact that they haven't been certified as reclaimed means that the company is still hanging on to them. Some of that stuff is now forested land again.
So there is important work under way to do that, but the land issue does remain a significant one for us. I think Dr. Kasperski's lab is actually involved in dry stackable tailings.
You may have spoken to that.
