I vaguely remember either Rowe or Calaway stating that Rhyolite Ridge has a number of favourable aspects over the Jadar project held by Rio.
Or it might have been in comparison to LAC's Thacker Pass, I forget which.

Some analysts have predicted that Rio will put Jadar on hold/backburner, whether this is because they are happy to buy out the only other similar project to it globally, in a far better location (INR) or whether or not they just dont see it as economically viable in the current market remains to be seen.

Regardless INR's experience management team will get this project to market with a far lower cost than a lot of other producers out there. In particular Rio's current borate mine in California will cost far more to extract Boron than this new long life project.
