agree with all that but from mine design point of view one needs indicated resource. even where they marked the first 2 open pits the areas have huge gaps left undrilled.
Funds or Instos will not take any scoping study seriously if it's done on the back on inferred resource. Infill drilling is never exciting but it does build confidence when serious long term investors as pension funds are considering to buy and hold.
During all presos they talk about mining while not have an ounce of indicated resource. Funds will not look at POD seriously.

But you are right the geology is well understood. Yes they may find couple of more high grade zones but everyone can see the big picture - from individual investor point of view.
Most Funds have lot of constraints where they can invest and how much.
