Four economic porphyry Cu-Au deposits occur at Northparkes, New South Wales: Endeavour 22 (E22), E26, E27 and E48.

Nine intrusive phases have been recognised, with a common sequence of emplacement recognised in all deposits. Pre-mineralisation intrusions include coarse-grained, equigranular monzodiorite and equigranular to weakly porphyritic biotite-quartz monzonite (U-Pb SHRIMP...[Show more]
