Agreed that the valuation is held back by perceived short life.

My simplistic comparison shows PNA on nearly 30 times expected future earnings, EQN on over 21 times, and OZL sitting on 15.9 times expected future earnings.

On the other hand, my comsec charts tell me that PNA and EQN have already risen much more in percentage terms than OZL.

On top of that we have almost every analyst telling people to pile into copper stocks, so the general sentiment is pretty positive.
