You just made me realise that (if true) this move by Zijin is to get information.
Knowing they couldn't get the support (50%) to sack the board.
But calling an EGM in itself is bad. Just hearing about such a move brings negative sentiment toward the BoD.
They hope that AVZ might release a progress announcement to combat any negative support to call an EGM, which was my initial thoughts as to what the BoD should do.
Or they plan to drum up discontent amongst shareholders and badger the BoD at the EGM to tell them what's going on.
Because there's no way they'd get a 50% vote.
If they have to cold call just to get 5% for an EGM, no chance of a 50% vote right?
So I agree, fuck 'em, keep them in the dark.
Besides like I said, I believe it's too late now
