Okay. This will take maybe 32 seconds.
You're right about the grade of the resource, and it gets back to your question about the oil sands economics. Syncrude, the Shell part that you saw, and Suncor are the best deposits. They're the ones that were developed first.
In the presentation I left for you, there are a couple of charts looking at the quality, and there are changes in the quality. This is basic resource economics. As the price goes up, the stuff that wasn't economical before starts to become economical.
You still have companies buying leases. You have Royal Dutch spending hundreds of millions of dollars on leases. They're still in the very early research stage of studying how to get this stuff out. It's oil and carbonate rather than oil sand.
So that's what you get when you have this increase in oil prices. Does that mean that the cost doesn't go up? Well, no. It costs more. There's more competition. I guess that's the point I'm trying to make, that as this industry is developed, we just see more and more competition, which is great for our business.
