There's a lot of research going on in tailings reclamation basically looking at trying to get the tailings ponds to settle faster so we can reclaim. But the other issue in getting the tailings ponds to settle faster is that if they settle faster, they'll release more water, which we can then recycle. So there is a lot of work going on in that area.
There are two beliefs in terms of what a reclaimed tailings pond looks like. Does it look like a dry landscape where we can put in trees and restore the forest? Or is it a wet landscape where there could be a lake that could eventually be used? So there are those two different approaches, and there's a lot of debate about which approach is the better approach to be used.
I'm currently involved in the tailings project at the University of Alberta through the Alberta Water Research Institute. It is looking at accelerated tailings densification, if you will, to try to get more recycled water and to eventually reclaim the tailings.
So there's a lot of research going on in that area.
