Were they holding off reporting on the poor grades in the vain hope that grades would improve?

If they knew the grades were bad from day 1 of pouring (which i agree they would have known) then surely they were just protecting the boards backs by not leaking this information to market as a huge drop in the share price like we have seen would have led to the possible removal of directors and board members at the AGM last month.
