Ah, my mistake. Either way, that's more than triple the cost for only an additional 10ktpa. And it's a low grade mine in comparison to CYM. And then - as you've said - the efficiencies of dealing with copper plate are huge and save millions of dollars each year.

Off-topic;Personally, I wouldn't mind CYM utilising the concentrator to get additional tonnes shipped. All of these other projects are concentrate, so it's clearly economical. By diverting some of the cash flow towards the refurbishment, we could very well be shipping an additional 25kt+ of copper, concentrate equivalent, on top of our 25ktpa copper cathode, for a rather minimal cost...

Perhaps this is where Barry's estimate of 80kt-100kt comes into play. Upwards of 50ktpa at Nifty, with two additional mines producing 25ktpa .
