Pongkor’s gold is of epithermal origin, meaning it was carried and deposited, along with other minerals, by the movement of hydrothermal fluids through rock factures that subsequently formed quartz veins. The bulk of Pongkor’s gold is hosted in four main quartz vein systems formed 8–9 million years ago, which are themselves situated inGold.
