Porphyry copper deposits are copper orebodies that are formed from hydrothermal fluids that originate from a voluminous magma chamber several kilometers below the Geology of Porphyry Copper Deposits. Understanding Geology of Porphyry Copper Deposits and formations using models around the World.
Porphyry copper deposits are found around the world, most commonly in areas with active or ancient volcanism (Fig. 2). The economic viability of porphyry copper deposits is dictated by the economy of scale – they typically are low grade (average % copper in 2008), large tonnage (typically hundreds of millions to billions of metric tonnes

• Coppergold mineralisation in the Wainabau/Waimanu area appears to be fault/fracturecontrolled. • other minor, noneconomic, mostly gold accumulations in hardrock and alluvial type environments. The only mineralisation to be examined in more detail will be that occurring within the Waisoi porphyry copper +/gold deposits.

Alkalic porphyry deposits are uncommon, and are associated exclusively with coppergold mineralization. Multiple intrusive phases are common in most porphyry deposits, with one intrusive phase typically contributing most of the magmatichydrothermal fluids and metals. Porphyry deposits were originally described as
