That's a great question, because I think what it will help to identify is the opportunity to talk about a legacy that's sustainable. Any time you put people to work, you're creating a legacy, you're building skills, you're building knowledge, and you're building experience they can take elsewhere, if that's the opportunity and that's their desire in the future.
What we're seeing with more and more companies is that they're hiring more people from the local population. There are training programs that are more localized to encourage more people to find the skills and the experience through the training programs, so that they can then participate in the local projects. I think that in regard to sustainability, while the ore resource might be diminished or taken away, what you have is a group of trained individuals and companies that can then provide opportunities elsewhere, or go elsewhere for the same kind of work, or deliver the same kind of service.
