I can go first. As I mentioned, the investment tax credit that exists today, the clean technology manufacturing investment tax credit, does apply to limited expenses related to mining.
I'll give you a real example. I can buy a pickup truck, get a 30% discount to drive that around at surface and not have to bring one tonne of nickel to surface, but for the cost of ventilation to keep our workers breathing underground, the electricity to power our equipment underground and even the bolting to protect our drifts underground—our tunnels underground—from collapsing, not one of those expenses is eligible.
The fact is that we have to go further and deeper in Canada with existing mines. Again, we're not running out of minerals, but the cost gets greater with greater depth, and some of those expenses are not eligible.
