  • Gold in porphyry copper deposits: its abundance and fate ...

    Gold abundances in porphyry copper deposits vary greatly, complicating efforts to define gold-rich porphyry copper deposits. The original definition was based on the Au/Mo ratios of porphyry copper deposits with no reference to their copper content , and resulted in the suggestion that gold-rich deposits were found largely in island arc regions (Kesler, 1973).

  • Porphyry Deposits 101 – Doubleview Capital Corp.

    Porphyry copper-gold deposits form in a variety of volcanic environments, most commonly in continental margins and intra-oceanic arcs. These are large scale magmatic-hydrothermal systems associated with a series of porphyritic intrusions, which result in extensive alteration footprints that we map and model to target high grade copper-gold mineralization.
