There's kind of a long list.
For many of them, fundamentally, we just haven't found viable deposits in Canada yet through our exploration efforts. I think that's one of the reasons some of them aren't extracted here by us. I think the challenge with what we do with all of the waste is becoming more and more of a preoccupation for us, as well as for society.
This is really why we're focusing on looking at what we already have within our portfolio, our ore bodies and within our streams that we can extract. That means that the material is here, but it's not necessarily a new mine; it's within our own processes. We're looking on our own doorstep to see what we can do to solve this problem and to support the economy and the growth of the green economy. That's just the choice we've made at the moment.
