FYI the bettermeetsreality site you link to is SEO spam. But anyway, those numbers sound about right, here's what wikipedia (and their source, https://doi.org/10.1787/uranium-2018-en https://doi.org/10.1787/uranium-2018-en) says: > As of 2017, identified uranium reserves recoverable at US$130/kg were 6.14 million tons (compared to 5.72 million tons in 2015). At the rate of consumption in 2017, these reserves are sufficient for slightly over 130 years of supply. The identified reserves as of 2017 recoverable at US$260/kg are 7.99 million tons (compared to 7.64 million tons in 2015). I wouldn't be too worried right now though, because Table 1.1 in uranium-2018 shows that the known recoverable uranium sources @ $40/kgU grew 50% between 2015 and 2017, and known recoverable uranium sources @ $80/kgU grew 4.6% over the same time period. No one's going to go around prospecting unless they think they can make a profit doing it.
