Of course, we process several products in Canada. I don't have the exact figure. The fact remains that we are a part of a free market and that in that context it is up to industry to determine if that is really worthwhile. We have also carried out studies. Where copper is concerned, we have determined that it is more profitable for Canada economically speaking to only do the mining extraction, and not do the rest, the subsequent processing. The case was not exactly the same for all of the minerals. We work with industry in order to find ways of adding value to resources here in Canada. We have managed to do so in certain situations.
Be that as it may, you are correct: in many cases we can't process the products either because of the cost of energy, the cost of labour, transportation, infrastructure, and so forth.
