Some of the biggest man-made holes in the ground are porphyry copper mines: Bingham Copper Mine, Utah, and Chuquicamata in Chile, and two of the largest. A porphyry is not a rock type, but rock with a particular texture. This porphyritic rock has large feldspar crystals in a finer grained matrix.

Porphyry copper deposits of western USA are very large low grade deposits dominated by disseminated Cu mineralisation but commonly with appreciable Mo and Au. Many deposits began as gold camps. Mineralisation is centred on, and mostly within, near surface quartz monzonite intrusions in which there is inner and deeper concentric Mo-rich shells.
