The only other serious positive announcement it could be is an extension to the offtake agreement with Jinchuan or a new one at that (if one can deem this to be 'serious' enough to warrant a trading halt).
Otherwise, takeover news would be naturally nice.
Would that mean the 'proposed buyer' (if Oz company)would also have to request a trading halt ?

Either way, the recent downward selling is either 'tricks in motion' or fair dinkum stuff.
