No, but typically if a railway is built or you have a highway, then your transportation costs are minimal. Where it starts to make more sense is when you look at regions that don't have that infrastructure. So if you have to factor in the cost of $4 billion to install a railway so you can access a mine, for example, it's starts to become a different equation. With this type of solution you wouldn't need to put that capital investment in.
So in Canada's north there are numerous stranded resource plays that haven't been developed, because the companies, quite frankly, don't have $4 billion to invest in an all-season road and a deep sea port so they can extract their resources to markets—not to mention that the installation of those roads and deep-sea ports is going to have negative impacts on the environment. We think the environmental approval process is going to become increasingly challenging. The easy stuff has all been found, in our opinion. In the process of developing stranded resources, should we not be looking at other ways of doing this?
