The Qiuguobi gold deposit is a recently identified gold deposit of silicified fractured altered rock-type within the Yalujiang metallogenic belt, with proven gold resources of ∼9.6 t at an average grade of 3.2 g/t. Exposed lithological units in the mining area exhibit a banded distribution and are dominated by the Paleoproterozoic Li’eryu (Pt1lr), Gaojiayu (Pt1ghyp), and Gaixian formations (Pt1gx) of the Liaohe Group, together with Cenozoic Quaternary deposits (Q). The Gaixian Formation outcrops in the northern and central mining area and consists predominantly of low-grade metamorphic clastic rocks, in which biotite schist is the dominant lithology. This unit constitutes the principal wall rock hosting the gold orebodies. The orebodies of the Qiuguobi gold deposit occur exclusively within biotite schist of the Paleoproterozoic Gaixian Formation of the Liaohe Group. They are predominantly vein-like and lenticular in morphology, with some exhibiting branching and merging characteristics. Their distribution is closely controlled by ore-bearing fracture zones and lamprophyre dikes and is characterized by discontinuous extension. The ore-bearing fracture zones are 2–8 m wide and display well-developed silicification and pyritization. Orebody thickness and gold grade increase significantly at the intersections between fracture zones and lamprophyre dikes.
The first stage is the quartz–pyrite stage (Stage 1), representing the earliest mineralization event. The second stage is the quartz–polymetallic sulfide stage (Stage 2). Smoky-gray polymetallic sulfide veinlets approximately 1-cm-wide crosscut the earlier milky-white quartz veins, and oxidation of chalcopyrite to malachite is observed in field outcrops. The third stage is the quartz–ankerite–polymetallic sulfide stage (Stage 3), which mainly occurs as hydrothermal breccia within fracture zones and represents the principal ore-bearing style of the Qiuguobi gold deposit. It is characterized by breccias formed through tectonic fragmentation of earlier quartz–sulfide veins and wall rocks, subsequently filled and cemented by quartz–ankerite–polymetallic sulfide assemblages. The fourth stage is the calcite–quartz stage (Stage 4). Calcite–quartz veinlets crosscut the hydrothermal breccias formed during Stage 3.
