History of discovery of Sungun, a world-class porphyry copper deposit, NW Iran Hashem ETMINAN Email: hashem.etminan@gmail.com


Significant porphyry-copper style mineralisation at Sungun was discovered by the author in 1977. This was based on field and laboratory studies of favourable foot prints, geological setting and the presence of distal porphyry-copper mineralisation in Iran. In 1988 a major exploration program was launched by National Iranian Copper Industries (NICICO) and results of subsequent feasibility studies carried out between1997 and 1999 vindicated author’s exploration model.
The estimated reserves at Sungun are around 1billion and 700 million tonnes with proven reserves of about one billion tonnes at a grade of 0.62% copper.
The Cenozoic volcanic belt which resulted from the subduction and subsequent continental collision, extends from Turkey to Pakistan. It hosts world-class porphyry copper deposits in Iran (Sarcheshmeh and Sungun) and Pakistan (Reko Diq , and Saindak).
Skarn-type mineralisation at the Sungun deposit had been mined since ancient times. The mining at this low-grade deposit was abandoned in early seventies. Extensive hydrothermal alteration zones around Sungun are associated with porphyritic granodioritic to monzonitic rocks. The exploration model was based on favourable structural features (such as intersection of several major fault systems), presence of hydrothermal breccia, and stockwork-style copper and molybdenum mineralisation. Extensive potassic, phylic, argillic alteration surrounded by a regional propylitic alteration constitute a distal alteration footprint of mineralisation. Fluid inclusion studies of veins and alteration minerals provided additional constraints for discovering world-class mineralisation at Sugun.
