Hey BW. Slipped through the filters before my coffee kicked in.

I'm almost certain that most of the mineralization is in discrete zones. They'd have an idea of which metal lies where, and they'd purposefully extract them discretely. They'd have a gold stream of processes, a Ni/Cu stream, and a chromite. Where the minerals overlapped, they may well have to forego recovering one metal in favour of another, but that's not always the case either. If all the metals were in one single truckload, they'd have to make decisions about the best value that could be obtained from that load, because optimizing chromite might mean no nickel at all, for example. But optimizing nickel might also optimize the gold. Overlapping mineralization zones would likely present problems, but separate zones would likely not.
