Does production == having the resource?

Asking because I think it's possible that many places don't bother to mine it due to a combination of regulations and cost.

So, Australia is where most of the uranium is :| Also, Russia does seem to have significant reserves that could be mined.

My official study was in the area of uranium enrichment. The situation in Soviet Union was always following - mostly Kazakhstan, Uzbekistan, Tajikistan mined the raw uranium and did first enrichment pass (I grew up in one of that areas), and then final enrichment was done in Russia. I’m not involved into that anymore for more than 20 years, but I doubt that situation has changed significantly as it requires significant capital investment, plus know-how…

Ukraine has a large deposit of uranium as well.
