Since we don't have anything built yet let alone a mine, the CDN$ vs. US$ costs have gone up proportionally for everything from all the equipment required to not only build, but operate the facility. The US dollar goes both ways and unfortunately, we are on the wrong end of the stick right now for that. It sure looks great to convert copper prices into Canadian bucks and say "wow, look at this!" but not when you first have to build and buy everything in US dollars just to get started. The converted price of copper is nowhere near a one way street for us...
