We get into this in that same section of the report on adding value. It's the notion of sustainability in the creation of small and medium sized businesses that initially may be created around a particular major project or operation. The desire would be that they become sustainable, so that whenever the mine or whatever wraps up, the businesses don't all wrap up at the same time.
What we found particularly interesting about the Chilean example was that they started out by trying to create more value added in a cluster of SMEs around particular mining operations, enterprises that were, at the beginning, providing relatively low-value and low-skilled services to the mines. But the objective was to move the value chain up, so that not only would those companies grow but also that when the resource were no longer there, there would be more hope for these companies to actually be sustainable.
