Both at 12:52am for 54,305.68 (collectively) at 0.22 which could have triggered buy alerts for ther traders further pushing the price up. These wiped out the 0.22 buy lines leaving on $500 dollars worth left which were quickly snapped up. To put this into perspective that's 246,884 units or 0.57% of the total float. That's 0.1% less than the 20th largest holder, MOGGS CREEK PTY LTD who holds 0.58%. Seems like a well thought out purchase with no need for announcement... (if they were purchased by the same person/group) which looks the case.
