Thank you. That leads me to a question. One of the other statements made was that it's good PR and good business to be able to do this in the most environmentally sustainable way.
Mr. Nelson, when you were talking about your technology, you said you'd been working on this for, I think you said, the last seven years, predominantly working your technology to get it more value-added in the supply chain in terms of just dumping the stuff in tailings ponds as opposed to getting other products out of it. You've done the demonstration projects, but you're slow to get adoption.
It seems to me there's a tremendous business case in this, with the billions of dollars that could be added with the zircon and the extra bitumen that we're getting out of the oil sands. Is it just a matter of lack of resources? The business case seems to be there. What are the other major stumbling blocks to the adoption of these technologies?
