Rio is already very confident about its prospects, after spending millions of dollars.

"Jadar Mineral Resources have increased to 136 million tonnes. Rigorous ore body knowledge studies and analysis completed in 2016 increased confidence in the size and composition of the Jadar ore body."

I don't think this success is going to brush off onto JDR until JDR shows it too has resources. "Nearology" is a dangerous game to play when the behaviour of jadarite (a totally new mineral) is not yet understood.

I have bought because I am taking a gamble on JDR finding resources.
