We have gaps across the whole range of skill sets, including the trades, the university level, and engineering. It really depends on where you look on how acute it is.
For example, metallurgical engineers are extremely rare these days. We haven't seen the turnout from our schools to meet the demand for metallurgical engineers. There has been a far greater take-up for mining engineers, and a lot of our schools across the country are full to overflowing. We are starting to see certain niches being addressed better than others, so it really does depend.
Of course, part of what we're also facing is that with some of the skills we need in the trades—electricians, auto mechanics, etc.—there are other sectors in the economy that are facing the same shortages, so we're competing for a lot of the same people.
