Orogenic gold deposit with quartz vein-type and fractured altered rock-type mineralization styles, controlled by a ductile shear zone. Host rocks are chlorite phyllite and siliceous slates.
Controlled by EW-trending brittle-ductile shear zones, are hosted in greenschist-facies metamorphic rocks. Reserves >40 t Au.

In Guoluolongwa deposit, Au mineralization mainly occurs in lenticular quartz-sulfide veins formed in the metamorphic rocks of the Ordovician-Silurian Naij Tal Group. There are six auriferous orebodies labeled as I-VI in the host rock. The veins exhibit a significant inclination of 45โ€“75ยฐ towards the southern direction (170โ€“180ยฐ), spanning lengths ranging from 40-1340 m and widths of 0.5โ€“2.0 m. The veins possess an average gold grade of 6.8 g/t, with certain areas containing visible gold reaching an exceptional grade of 274.0 g/t.
A pre-ore (stage 0) and three ore stages (stages I, II, III) are defined at the Guoluolongwa deposit based on mineral assemblages, textures and crosscutting relationships between veins. Stage 0 (Pre-ore vein): Small euhedral pyrite grains and pyrite veinlets can be observed in the phyllite. Stage I (Pyrite-quartz vein): Coarse-grained or disseminated pyrites can be observed within the coarse-grained quartz veins. Stage II (Quartz-pyrite vein): Large amounts of massive pyrite can be found in the coarse-grained quartz veins, and quartz-pyrite vein (stage II) is obviously more enriched pyrite than pyrite-quartz vein (stage I). Stage III (Calcite-quartz-sulfide vein): There are various sulfides such as pyrite, chalcopyrite, sphalerite, and galena found in coarse-grained quartz veins.
