Does seem to be a lot of knocker-twisting at times...

5N would be quite nice, although obviously the extra work that has to be undertaken to achieve it in terms of the mettalurgical processes would need to be worth it. And consistently achievable - we don't know whether the sample used is from a higher-yield part of the prospect which would make itself more amenable to higher extraction outcomes, and other samples from elsewhere wouldn't be conducive to a higher recovery rate. If that might be the case, you don;t want to back yourself into a corner reporting five 9s now, and then not being able to deliver later as you have to move into other lower-quality parts of the ore base.
