UBR & PYRI have said a few times that I believe that UBR is the better bet as they don't burn cash as fast and don't dilute their shares so aggressivly. However, if this project is viable, positive news should spike PYR 100%+ easily. I don't own much PYR shares but I think it might be worth owning more for the long-term if I can get a dip, and luckily it hasn't run yet like UBR.
