Bob I think this is something that will be more important further down the line and once they are in production.
But looking at this now @ 30MC? at the beginning of their story with so much "potential" I see more chance they will increase in MC in the ST-MT as they build their resource and talk about being a X,000 oz /pa producer than decrease due to potential mining difficulties 2-3yrs away. All IMO (and I am not even a holder at the moment!).
