Berkeley’s nuclear re-rating

Analysts believe Berkeley Energia (BKY:AIM)is worth four times as much as its current market value, assuming that it can successfully raise money to build a uranium mine in Spain. The project economics are very good for the Salamanca project; Berkeley is one of the few miners that could theoretically make a profit at current depressed commodity prices. Is this a no-brainer stock to own or should you treat the story with the same caution applied to most other mining stocks in the current environment?
