I think if ppl are going to base investment decisions on this preso, then (obviously) that's their call, but I for one certainly wouldn't be doing it on a finance guys take on mining operations, metallurgical results, etc, or on his ability to present in public (finance ppl are generally known to be introverts, and public presentations is probably their biggest fear of all). Sure, he'd get practice at each AGM, but that's purely presenting on facts and figures, not discussing the specifics of a mining operation - which is where he stumbled slightly.

So, on this occasion, I agree that JC did an OK job stepping in and presenting a 'whole of coy' approach.

No better or worse in presenting than any other finance guy would in the same situation. I certainly don't agree with you that he provided a better take than Nic normally does, (Nic doesn't come across as a confident public orator) but he does get his points across - as did JC.

As you say, each to their own!
