Ann: Trading Halt , page-12

I've had a bit of time to think this over and even though I have great faith in PNA management I don't think this is the right time to be buying anything.

Whatever cash the company has should be utilised to commission BH and Puthep.

Perhaps they are buying out the 10% Govt ownership of Laotian assets - salient footnote from yesterday's announcement :
1 PanAust?s assets in Laos are held by Phu Bia Mining Limited (PBM). The Government of Laos (GoL) has exercised its right to acquire a 10% interest in PBM. Results referred to in this announcement reflect 100% ownership of PBM. The GoL minority interest has been recognised in the net profit after tax attributable to PanAust Limited.

Not much use speculating, I guess we'll just have to wait for further announcements.
