Copper is KING,think bread and butter. Mining companies have a constant plan of building all of their ops revolving around COPPER. wHY DO THEY DO THIS. Here is your answer,boom and bust in the metals, because of swing prices, thus as was just posted here (100million oz gold and still counting)but mining cos, keep a focus that the MKT is very swing so they set a benchmark of production,that scale is COPPER PRODUCTION,generally the mill will be 100% design for copper recovery. That way they survive the throws of metal prices flux. That is survival to them. No they do not forget to process the other stuff, but Milo2, you are right,our value is entirely based on,COPPER.
