Great pickup Post Trader.
A few points:
Oil price used is going to be very important in PFS. I expect Oil price to count for 25-28% of operating costs and it's moving (down).
Surprised they are now fine tuning pit wall angles (informed by geotech). That will affect waste/ore ratio and costs positive or negatively.
PFS out by Mid 2019. What about that bragging that the'yd accelerate it? Nov '17 to Jn '19 is 19 mths min. I guess it has to be done right. "measure twice, cut once".
