20's geez I think you are being kind. Killer announcement for this stock imo. Long time to recover if at all because if the grades are that variable (meaning bad imo and unreliable) then the ROM blend will likely not help. Messing up grades - geez I know another ASX stock did the same drilling LOL. Glad I am out of CCU long time ago. Hope it comes good one day for those stuck in it at huge losses.
