Adularia-sericite-type epithermal gold deposit, related to a Late Triassic granite intrusion that was in turn intruded by a Cretaceous granite stock and is overlain by a sequence of rhyolitic lavas and tuffs with minor dacite. Both the intrusion and the volcanic sequence are intruded by rhyolitic porphyry dykes. The ore bodies are controlled by a series of NS-, NE- and NNE-trending faults. Most of them are hosted within the dykes or in the lavas surrounding them, and one of them is hosted within the Triassic granite.
Eight of the orebodies are hosted in rhyolitic lavas, five are hosted in rhyolitic porphyry dykes, and one is hosted in Jurassic granite. Gold orebodies are commonly brecciated and the breccias are bounded by faults. The size of the gold veins varies considerably, from 50 to 800 m in length and from 1 to 7 m in thickness. They extend to depths of<400 m and have grades of 3–10 g/t Au. The largest vein is 770 m long, 6.70 m thick on average, and has a vertical extent of 358 m, with an average grade of 8.8 g/t Au and 75.8 g/t Ag.
