Thanks team. I always think I am 'invested' in my investments too but don't have the analytical skills that you guys have.
Couple of questions. What is PON?
I cannot see the $AU / US$ conversion going to 0.76 to 1.00
The other ting in my mind is that if you see a Ni price recovery and wait until it hits $22335.00 per ton which is about the maximum predicted for 2020 ( looks a long way away from the $12000's or $13000's we see now) Then by the time you build and begin the mine one may well have past the peak?
One can never bet definitively on the exchange rate and cannot bet on an ever increasing price. Things just do not work that way. So it may be better to make a start somewhat before the $22355/ton than work on reducing costs and efficiencies..
Still, more core thing is AU$ 0.76 to US$1.00.....probably not in a very long time!
There you go. Gunna keep holding for an indefinite time. Either get my $$ back or the kids can inherit bugger all!
