Really? This is what most are embracing?

Yes, this is what a realist would anticpate on laws of probability.
24kt at PB by design. It would be modelled on AN although the harder ore would be compensated for this time round imo. So optimised maybe 28kt. AN is good for the 14 odd kt depending on rom grades. I can see issues doubling production without crusher upgrades at AN, so maybe 18-20kt with additions excluding crusher upgrade. Maybe one or both crushers might make its way to PB from AN.
So 40- 45 kt is a reasonable expectation 2020.
An economical resource to extend lom should be proven around AN over the next 24mnths.
