So looking at -- so conceptually imagine 27 million ounces conceptually with a $1.3 billion investment, 800,000-plus ounces a year, at sort of the costs that you see now, we don't have to -- you could do it your own and so it makes real returns significant returns. So and part of that -- so you're right, that we needed a tailings disposal, site that will support that sort of size of mine, and we are working on that. We've got a number of targets that we're evaluating or potential sites that we're evaluating. And then the process side is very simple. Originally, the team was looking at a concentrate part, so you have a high-grade zone, direct fee, a high-grade ore. You have the lower grade ore and some very big stockpiles at around three-grams. Josh, are you got that? And so the idea then is to take part of that floater so you concentrate the gold. And then part of it that you oxidize, through a dump each base process, just putting water through a dump and you partially oxidized the sulfide. Yeah. So what we're doing now, is we're looking at -- so -- and that's all quite risky and it's re-handled. So what John and the team have done is that, we have true-tried and full-scale confirmation of being able to concentrate, and do ultrafine brand, both in Tongon and Kibali. And then the idea is you take that concentrate, ultrafine brand and it just starts the oxidation process and finish it in case. And so that you can control the partial -- because all you want to do is take the sulfide down, the energy down and they said they can put it through the autoclave. So you're taking a large amount of the lower-grade ore concentrating it producing the sulfur content and putting it through the process. And so -- and so the back end of the mine is the same and the opportunities that we're now modeling are quite exciting, because 800,000 ounces is the bottom-end of a profile that we're doing a trade-off on and as you increase that efficiency of that concentration, so you drop the costs. And as you drop the costs, you unlock the reserves. And so that's the model that we're doing now. And by quarter three, you will have a good handle on the actual – the scope. We've got a scoping study which works, and we will have a sort of pre-feasibility type project by the back half of this year. By next year we'll have – finished that. I don't know, John, do you want to add anything to that?
