Resource calculations
It appears that method of calculation of resource has changed and there is an apparent different standard compared to 2012. The same scenario played out with MOZ who also had great new drill results after a promising inferred resource , the later calculations were disappointing when moving from inferred to indicated. I have not looked back to see if the grade cut-off changed but it is a more complicated issue than just that, perhaps there was accounting for nugget value. resource calculation is a lot more complicated than plugging figures into a calculator. Itis obviously advantageous to have the most accurate figures possible, any error leading up to a BFS would be actionable or more likely SP would crash (how do you crash from .8c LOL).
