From my personal experience and my experience over the 18-odd years I was at Cambior, we worked quite well in general with the mining industry.
To be honest, I would tell you that, when you come to a country where you don't speak the language, you obviously rely on people you trust. So we would take some of the people who worked with us for the first two or three years. After that, we would try to keep it at no more than 5% Canadian workers to about 90% to 95% local workers.
That's also the proportion we were trying to maintain across industry. I'm thinking of service companies such as geophysics, drilling or laboratories, for example.
In this regard, I certainly have more experience in Chile, Peru, Colombia, Argentina and Brazil. Unfortunately, it may not be as fashionable to talk about it now, but in the six years I spent in China, we had roughly the same ratios, even though it was more difficult to speak a Chinese language than Portuguese or Spanish.
