LUO Xi Cheng;YU Jing;LIAO Yan Heng;Jiangxi Provincial Geology and mineral exploration and Development Bureau of geology;  
Yu Jia Li area is located in the west of Jiangxi province, Administrative divisions under the jurisdiction of the town of Yichun city rui, There are mainly oxidized ore and primary ore in the mining area, The oxidized ore bodies are mainly found in the calcareous mudstone and silicified weathered rock residue of the Qinglong formation in the lower triassic, Weathered reddish brown gravel clay with siliceous gravel clay, There is no obvious boundary between the orebody and the surrounding rock, Through the recent exploration work, There are three oxidized ore bodies in this area, The shape, occurrence, distribution and location of the gold ore body of oxidized ore have been roughly ascertained, The average thickness of the orebody is 5.37 meters, It is an easy open pit orebody. The ore mineral assemblage is simple, Gold is mainly composed of fine-grained natural gold, The formation of gold intergrowth exist. Average grade of gold ore 1.25×10~(-6),The genetic type of the deposit belongs to fine disseminated type,The original gold mineralized bodies have been discovered by drilling in the mining area,Is a Carlin type gold deposit in the area representative,Prospecting for fine disseminated gold deposits in the area has pointed out the direction.
