The Chaijiagou Mo deposit lies within the central segment of the Yanliao Mo Belt. Mineralization is featured with concealed veinlet-disseminated quartz–sulfide orebodies, predominantly localized in the cupola of the Middle Jurassic granite porphyry. Hydrothermal alteration is intense and widespread. Two main alteration zones have been identified based on field and petrographic observations: a deep potassic alteration zone and a mid- to shallow-level phyllic alteration zone, both developed within the granite porphyry. Four paragenetic stages of vein formation are determined in the Chaijiagou deposit, each with distinct mineral assemblages. Stage 1 represents the magmatic–hydrothermal transition and is marked by veins composed of quartz, K-feldspar, and magnetite. Stage 2 contains the main Mo mineralization and is hosted within quartz porphyry. Stage 3 veins occur mainly in shallow and peripheral parts of the deposit. These include quartz–pyrite, quartz–pyrite–sphalerite, quartz–pyrite–sphalerite–galena), and quartz–sphalerite–galena veins. This stage marks the introduction of Pb–Zn mineralization.
