40 Derick Ma: And let me ask you and ask a question on Khoemacau. You mentioned the potential for M&G to look at additional expansion to 200,000 tons of copper per year. What would that mean in terms of silver deliveries in terms of your AOI -- Martin Raffield: Look, it's very early stages, at the moment. They have just announced that they are thinking about moving to that or looking at that sort of level. Obviously, it would be an increase, but I wouldn't want to put a specific number on that. I mean, we've said that with the latest expansion, there's a 35% increase. So, beyond that 130 to 200, I wouldn't ratio it up, but it's going to be an increase and it's going to be relatively significant. It is not a further increase up to 200 million, no. Heiko Ihle: Thanks for having us. Very comprehensive. We got a good part of your team sitting up on stage here today. I assume, between everyone here, you talk to dozens of investors, operators, stakeholders, every day. In your opinion, given that we have a wide range of the team here, what are the three assets of yours that are most misunderstood or even misvalued by the market, especially given Martin's comments in one of his four or five slides, that there [are] two million meters of drilling per year. William Heissenbuttel: Okay. To me, the one asset that I think the market doesn't really, fully, fully appreciate might be Mount Milligan. We try very, very hard to say life-of-mine extension, that's great -- our top asset now has two decades of mine life. But when we just casually reference the fact that they're building a tailings storage facility that's going to accommodate material well beyond that. And listen to Paul Tomory talk about that asset -- he's talking decades beyond the two decades. I just don't think that's in anybody's estimation right now. I think the other asset everybody underestimates a little bit because there just isn't enough information right now is how big could Fourmile get. I think in your mind, you kind of think, oh, it's one of the greatest exploration stories ever. But do we really understand the potential of the decades of potential production that's out there. Beyond that, I'll just pick two smaller ones. Because Wassa has been owned by Chifeng for the last few years, there just isn't a lot of, sort of, airplay for the asset. You don't -- there aren't quarterly results. There was a technical report that was issued, I think, at this point, it's a couple of years old, that shows the potential for that asset to go to 2049. Nobody knows, really knows that unless you've seen that report. Nobody really knows it.
