Scroogy,
PL171 20% VPE 80% BG
ATP574P 30% VPE 70% BG
The combined value of the above will be worth over $1.00 to VPE. Getting BG to release data on their reserve value is like extracting teeth from a chicken.
Have a look at the VPE news item on 26/11/2010 to get a better background. But the best thing to look at is VPE's top 20 shareholders. These guys know what they are doing.
