We are doing that as we speak for our specific design, which we've just tabled.
What I would say to you is that the model developed by DFO, which you have sort of tabulated there in that report, is actually an excellent model in terms of being able to explore all those sensitivities. You just need to plug in the numbers to explore the sensitivities. So if you plug in $12 million for the capital cost, the outcome currently shown in that report—that closed containment was barely profitable, including depreciation, at $22 million—becomes quite profitable at $12 million.
Please don't get me wrong: that was an excellent piece of work in terms of the full package. There was a lot of work done by DFO to construct that model. What you feed into it is very useful, so pick your starting point and explore. We are going through that very exercise now for our project, and we'd be delighted to report on that in due course.
