Prices in the spot market are well below the cost of production, it's been an industry in liquidation... but nuclear power plants need to keep running. Because it's been an industry in liquidation, production is going to be way less than expected consumption. On top of that consumers are just not price sensitive, as uranium is quite a small part of running a nuclear power plant. And adding more mines takes years, if not decades. Prices will rise, last time it went from $15 to $140 for uranium itself, and some mining companies did more than a 100x.

Interesting. What mining companies would be interesting to follow when this happens?

Just buy an uranium EFT (exchange traded fund), which will include multiple companies:

CCJ has the largest market cap and is the top holding in URA etf. I was thinking along the same lines as commenter above and bought some CCJ 2023 LEAP options a few weeks back.
