Based on my opening remarks, different critical minerals have different markets and different usage, so in aluminum, we're talking about a million tonnes, versus in scandium, we're just talking about double-digit tonnes—80 tonnes—that we're looking at.
It depends on, number one, in which part of the value chain, for instance, our domestic needs would be. Number two is looking at the global demand, especially in the advanced supply chain. Number three is looking at our capabilities in what we're able to produce.
