It's a good question, and it's a difficult one to answer.
I think most mines today have a finite life. By the time the mine moves into a community, builds the mine, extracts the resource, and moves out, you want to make sure that the mining company leaves a legacy. And that legacy often is a very skilled and competent workforce that can then move on to other opportunities, be it in the mining sector or other sectors, because they have transferrable skills now that can be applied to other sectors.
We see that in a number of mining communities today, where a mining company will come in and hire somebody where the hiring requirement is a high school minimum. The individual doesn't have a high school diploma, but they will still be hired. The company will provide the employee with company time to go off and write that GED or the high school equivalent, or to fund a technician or technology degree—something along those lines so they can get the most value out of the employee during the course of the mine. But when, in time, the mine does close—and we all know they eventually all do—this workforce is not left with nothing. They are left with a legacy, which is often a very skilled workforce.
