We pick up extra tonnes in my model for years 9 & 10 the PFS goes to year 8. Yes, there will be extra nickel produced and after the plant capital costs are amortised but in a NPV calculation, the discount rate is very high in those out years (specifically 1.10^9 & 1.10^10) so doesn't add much to the NPV and thus current SP. It's exactly the question I asked a the AGM as described I the answer by Mike Young described on my post 23/02/1914:13Post #: 37542881 on the other thread.
So in simple answer to your question YES. However, the most critical component is the nickel price used.
Now you can say half the time my answer is indecipherable rocket science (and that's being kind).
