Sunyelin copper deposit in Sichuan Jiulong is located in the north of Jianglang magma - metamorphism core complex, and is one of mining areas in Liwu copper mine. The Geological Characteristics of Sunyelin copper deposit was analyzed from the stratum, structure, wall-rock alteration, ore-body characteristics and ore nature. By deep proof with drilling, the extension variation in depth on S-3 and S-4 ore-body was studied. It was showed that wall-rock had a strong alteration. And its grade and thickness of the stratoid ore-body vary in depth. There are multi-storied ore-body with low grades. Metallization is connected with silicified quartz reef, sericitization and garnet, and so on. Thus there is a good prospection for hunting copper deposits surrounding the Sunyelin copper deposit.
