All of the things are reviewed.
What I was pointing out on lithium was just that there's the production of lithium and the processing of lithium, and that difference is quite profound. In terms of the production of lithium, the two largest producers, which dominate some 45% of the market, are the United States and Chile. The processing, of course, as you pointed out, happens more predominantly in China and it is significant and is certainly something that the market is responding to.
As I mentioned, there are some 20 different projects under way in Canada around lithium. They're in Quebec, Alberta and Saskatchewan, and they're using new and different ways of developing lithium so that there will be lithium supply to feed the value chains that we expect will emerge.
