Brasstacks,

Ag is usually locked up in the bornite, so recovery of silver will not add any additional cost to processing. However, Pb and Zn are not in concentrations high enough to justify building a separate circuit. If anything, they may be penalty elements that will detract from the value of the concentrate. Moly is occasionally intercepted in amounts high enough to bother recovering, but again it depends how easy it will be to extract the moly (classic cost/benefit situation).

The Pb and Zn are more useful in geochemical vectoring for high-grade Cu (as mentioned by the company).
