I find it very interesting. I know that in discussions I've had with Vale and Glencore, there's great interest now in being able to recover minerals through waste products such as tailings and so forth. As you say, there's active research and development under way to look at that.
There was something that I thought was interesting. Canada has the ability to recycle about 14% of its electronic waste. It is comparable, I think, to the U.S. When we look at European countries, that percentage is far lower. Is there something we can learn from those other countries?
