Keep in mind that it is 8.30am over in Perth where the company is based. We may not see an announcemet for another couple of hours.
After all why would they prepare a response during their 'easter holidays'. Also would have to wait for the company secretary to get in to be able to lodge it with ASX.
So if nothing by end of the day then I'd be peeved. Keep in mind that Aminex released their announcement on Thursday night our time.
