This approach has been used at the Pebble porphyry Cu-Au-Mo deposit in Alaska, driven by the geology and metallurgy teams. The key finding from this work is that the host mineral for gold varies with changes in the alteration assemblages, and that each association requires a different metallurgical approach to optimize metal recovery.
