Porphyry cores are formed under higher temperature and pressure conditions in deeper parts of the system. They typically contain copper-rich minerals such as bornite or chalcocite and yield copper and gold grades at multiples of KSM's reserves. World-class gold-copper porphyry districts usually exhibit links between the deeper, magmatic source ores upwards through transitional volcanic-hosted porphyries and skarn zones to replacement deposits including shallow vein systems. The six deposits in the area of KSM display this vertically evolutionary relationship. Furthermore, all four porphyry zones at KSM remain open at depth, with geological signatures that vector downwards towards higher temperature and pressure conditions.

Seabridge President and CEO Rudi Fronk said that "after we discovered the Mitchell Zone in 2006, we focused all our exploration efforts on defining reserves. At 2.2 billion tonnes of proven and probable reserves, KSM now represents one of the largest undeveloped gold-copper projects in the world. Six years of intensive exploration and data analysis strongly suggest that the six deposits in the immediate area are distinct yet related mineralizing events likely generated by a single magmatic source. The vertically-zoned mineral assemblages were then displaced laterally by regional thrust faulting. What is most encouraging to us is that the total displacement along these faults now appears to have been just a few hundred meters, not kilometers. The core should therefore be close to the existing KSM deposits at a reasonable depth. A magnetotelluric ("MT") geophysical survey conducted last year has identified several distinct resistivity targets which could represent the core.
