PRU has high C3 costs relative to price currently. Margin getting squeezed.
Similar to lots of goldies with C1 and C2 cash reported at 700-900$ they often leave out the C3 which is far higher.
However if/when gold recovers (depends on your opinion and outlook) PRU and existing producers will be first to reap the benefits. Bounce will happen before gold is 'officially' known as in a new up-trend. be sure of that.
