Seabridge Gold Identifies New Copper-Gold Porphyry Target at Iskut

- December 18th, 2018

The company said the discovery of a hydrothermal breccia confirmed that a porphyry source for the lithocap is nearby.

Seabridge Gold (TSX:SEA,NYSE:SA) has announced that this summer’s drilling on its Iskut project in northwestern British Columbia encountered the hallmarks of a large copper-gold porphyry system: a robust hydrothermal breccia containing abundant clasts of chalcopyrite-pyrite-magnetite in veined intrusive rocks and stock works positioned over a large IP chargeability anomaly interpreted as a sulfide-rich porphyry intrusion.

A total of 2,700 meters of core were drilled in the program.

As quoted in the press release:

The discovery of a hydrothermal breccia (diatreme) in holes QR-18-14 and 17 confirmed that a porphyry source for the lithocap is nearby. Diatremes are explosive volcanic vents produced in a solid rock structure by the energy from expanding fluids and gases evolving off magmas. Diatremes are commonly found above and adjacent to porphyry mineral systems which are their source of heat and fluids. Extensive review of the available data indicates the source for the diatreme is south and southwest of Quartz Rise, where glacial erosion has exposed rocks deeper in the mineralizing system. This erosional window provides the opportunity to explore into the heart of the porphyry system with much shorter drill holes from a lower elevation.
