Abstract: Jinjiaya Antimony Deposit is located at Xichuan fault polymetallic metallogenic belt in the eastern part of the Southern Qinling Mountains Orogenic Belt at the junction of Henan Province and Shaanxi Province，the metallogenic conditions of the mining area is good.In order to study the prospecting potential of the area，geological prospecting and study have been carried out in the mining area by means of 1∶50 000 stream sediment survey， 1∶10 000 geological sketch survey，1∶2 000 rock profile survey and trench prospecting engineering control，besides that，geological characteristics，ore-controlling factors，prospecting indicators and prospecting prospective of the mining area are discussed in detail.The study results show that:①the orebodies are mainly hosted in a set of black siliceous rocks and yellowish clay rocks at the bottom of Shuigoukou Formation of Cambrian System；②the ductile-brittle structure is a favorable space for ore-controlling and storage，which activates and migrates the ore-forming elements in the stratum，with the change of physical and chemical conditions，antimony and other useful elements are deposited and enriched at favorable areas，therefore，the antimony deposit is formed；③the method of 1∶50 000 stream sediment survey，1∶10 000 geological survey，1∶2 000 rock survey and trench exploration and exposure has obvious prospecting effect.Based on the above discussion results，two prospecting targets areas are delineated and antimony orebodies are found in the target areas，which indicates that the prospecting prospective of the target areas is good and they are worth conducting further prospecting work.
