From Stockanalysis following recent announcement by BOW/VPE:
"....Running a ruler over the potential at Don Juan, by applying an NPV of 85 cents per Mcf of gas and assuming that at least 400 Pj of gas will be outlined, produces a target valuation of ~$1 per Bow share and 70 cents per Vicpet share"
Thats 4x for BOW and 4.5x for VPE - PROVIDED THEY MEET THEIR TARGETS.
