RE:Good news about the copper. Copper and gold are often buds.Lots of people have been moaning about Brimacombe trading his shares, but NB he's not done anything on the recent dip - if he was a proper seller and had concerns about RUP, he would be dumping his stock - he's not doing that.
Agreed on the copper front PACO, a lovely addition for RUP and only supports the bull case.
I am very long RUP, but if you are looking for a copper play, check out Chile explorer Marimaca (MARI.TO)
