Finally shes blasting off...., page-15

They clearly have a strong interest in holding a major stake. Anything more is hypothetial and so we are, Im assuming, discussing what may happen if they do wish to acquire even further.
They could equally stay at 60% and just take full offtake as they are doing at Molly.
The ASX laws are in refence to the buying of shares. Approval for full ownership would obviously also have others concerns to consider. But as no one has offered any verification on what is expected it remains all hypothetical too.

I personally think Shenghe will just stick with 60% and do a full off take deal. By the time all the dust settles the share price would be much higher and maybe of lesser interest to push for the full holdings. Who knows. Its all hit and miss. Point being though nothing can be forced in acquisition.
