Gold occurs in quartz veins and associated altered country rocks at the Jabal Guyan ancient mine in southern Saudi Arabia. The gold-bearing veins follow northwest-trending fault zones which cut the Precambrian metavolcanic rocks of the area.

The Jabal Guyan mine, one of the largest ancient gold mines discovered in southern Saudi Arabia, is about 150 km north of Najran, a large town near the Yemen border.

Jabal Guyan is an orogenic gold deposit hosted within deformed Proterozoic metasediments and metavolcanic rocks. Two sub-parallel shears each host a steeply dipping auriferous quartz vein that can reach 2 m in thickness.
