Let me take that at a couple of levels. As you said, those two programs.... You can think of them together, one of which is trying to tell us where the deposits are that we don't really know about now, a kind of public science aspect. That's important work that the industry then builds upon and goes out and makes the finds. The second, and the targeted geoscience initiative is one, tries to take existing activities and see if we can go deeper, get more efficiency, get more extraction out of the mine.
You raise the point about how we evaluate these. Take the targeted geoscience for example. When we have a program like that, which sunsets and is due to end, we go through a pretty rigorous evaluation in which we go and talk to the people in the program. We talk to stakeholders and say, “What is this doing for you, what's the result, what's the outcome of this?”
