The Domeyko Cordillera and its associated copper mines and prospects are controlled by a series of coastal-parallel, approximately north-south oriented, faults and fault zones, which have played an intimate and intricate part in the evolution and development of the giant deposits located along the belt, including both hypogene (syn-mineral) and supergene (post-mineral) copper deposition.

The nearest four holes on the Canadian Creek Property to Casino have moderate potassic alteration to strong propylitic alteration, leach capping or incipient leaching, weak enrichment and hypogene copper-gold-molybdenum mineralization, which are typical of that occurring at the outer edges of a porphyry copper - gold - molybdenum deposit.

Hypogene ba-rich todorokite and associated nanometric native silver in the san miguel tenango mining area, Zacatlan, Puebla, Mexico.

The solutional sinkholes are formed by epigene processes and collapse structures represent failure into an underlying void, which may have formed by hypogene or epigene processes.

In operation since 1996, Carmen de Andacollo is an open pit mine which currently produces primarily copper in concentrates from the hypogene portion of the orebody.

The hypogene zone hosts 79.1 million tonnes averaging 0.26% copper, 0.020% molybdenum, 0.083 gpt gold, or 0.45% copper equivalent at a 0.21% copper equivalent cutoff.

At Altar East, new vertical drill hole ALD-176 (905 meters averaging 0.52% Cu and 0.29 g/t Au) entered hypogene copper-gold mineralization at 46 meters and exhibited a steadily increasing copper gradient and continuous copper-gold mineralization to the terminus of the drill hole at 951 meters.

The ore minerals in these deposits are scattered throughout host rock as what is called disseminated mineralization or they are largely or wholly restricted to quartz veinlets forming a ramifying complex called stockwork; both forms of mineralization occur In many deposits Many alkaline and calc-alkaline porphyry Au-Cu deposits have extensive potassic hydrothermal alteration halos, varying both laterally and vertically, with changes in pressure, temperature, eH and pH during magmatic, hypogene and subsequent supergene processes (Wilson, 1986).
