RE:Some perspective The marketing is over the top for what they have but guess trying to benefit early investors..
Anyway 0.2bcf isn't a "massive helium reservoir" in my opinion. Global usage is 6bcf per year of helium approximately so 0.2bcf won't have much impact at all on the global producers having a major new entrant I reckon... But being the US they could become a small modest producer given infrastructure already in place in the USA
"Extrapolating the new data to estimate the amount of helium beneath Pulsar's overall land position comes with large uncertainties, but 176 million cubic feet (5 million cubic meters) — the number one gets by multiplying 22.9 million cubic feet by 7.7 to cover 100% of the land position — "may not be too far off" the actual volume of helium in the reservoir, Gluyas said."
