Abstract: Guided by prospecting prediction theories and methods, a systematic analysis of geological processes, metallogenic tectonics, mineralization alteration, and various metallogenic information has been conducted. This study summarized the metallogenic geological body, ore-controlling structures and structural planes, and metallogenesis characteristics of the Caiwa Antimony Deposit, leading to the development of a “Trinity” prospecting prediction geological model. The Caiwa antimony deposit is a distal epithermal deposit related to magmatic hydrothermal activity. The metallogenic geological body consists of late Yanshanian plagiogranite and granite porphyry, while the metallogenic tectonics is defined by the Shuanghuaishu−Zhuyangguan fault and its secondary faults. The main metallogenic structural surfaces include nearly east-west trending ductile shear zones, folds, tectonic crushed zones, and lithological interfaces, with alteration primarily characterized by stibnite mineralization, silicification, and carbonization. The main mineralization period can be divided into three stages, with the quartz-sulfide stage being the primary metallogenic phase. There is a clear correlation between antimony enrichment and hydrothermal activity in this region, with the metallogenic materials and fluids mainly sourced from the Qinling Group and deep magmatism.
