If I remember correctly, as long as the grade is above 50 or 60 ppm, Sunresin DLE technology will handle the brine with no problem at all. I cannot recall who mentioned this before, but GR is likely to have a higher grade than Paradox due to geological formation. So, if the upcoming announcements are highly likely to push the stock price higher, brokers representing URA or other players will want to accumulate more at this stage, which would make some sense given the recent stock price movement around 11 cents. (These are purely my own thoughts and assumptions. Do your own research.)
