If you look back to the research notes published end of 2020 you will see comparisons of the unrisked NAV for the various different prospects. At the point HE1 were hoping to drill Kasuku, Itumbula and Mbuni in 2021. The assumed Gross and Net bcf were given as 5, 5, 7 and 4, 5, 6 for those three, respectively. Oxford University took macroseep samples at Itumbula in 2016 showing the deep gas concentrations between 8-10% helium. The NAV for Itumbula was about 3x that of Tai (5.4 P50 unrisked with 10% P50 CoS, 0.5 risked, compared to 1.7 with 15% CoS at Tai, 0.3 risked).
