STO-P'nyang Implied Valuation

STO has farmed into Pn'yang as part of the PNG-LNG expansion.
They are paying just under USD$0.30 / mmcf for a 14.30% share of the 4.4TCF Pn'yang.

Using this implied value / mmcf to value HZN's northern permits (closest to the (proposed) P'nyang-PNG-LNG pipeline, we get the following table.
I have split the valuation into Elevala-Ketu-Ubunto and Stanley due to the shadow hanging over Stanley at the moment.
