Hi Tarax,
Have held PNA for a few years, $1.50 is a realistic target, but gold and Copper prices need to be at current levels at least, and they have to increase production down the track.
Dont forget at $2 share price, thats over 2.8 Billion market cap, i believe the will have to have earninga forecast of 20c a share = P/E of 10, $300m profit,that still way off.
