野猫冲铜矿是小型的铜多金属矿床，储量丰富，所处黄茅地区属钦杭结合带北侧之萍乡乐平坳陷带北缘新元古代早期裂谷区西段。在地表地质调查、钻孔岩心的考察以及岩矿鉴定的基础上，对矿床特征进行了详细研究。研究显示矿床受断裂构造控制，与晋宁早期变海底火山岩关系密切，具有富铜低硫、两期成矿温度，成矿流体具有海底喷流与构造岩浆热液叠加改造双重作用，得出矿床为海相火山喷流沉积与构造岩浆热液改造蚀变岩型铜矿床。

Yemaochong copper deposit is a small type copper multi-metallic deposit with rich reserve.Its located area Huangmao belongs to the west segment of early Neoproterozoic rift in north margin of Pingxiang-Leping de-pression belt in the north side of Qinhang structure belt.On the basis of geological investigation,drilling cores ob-servation and rock -mineral identification,characteristics of the ore deposit have been studied in detail.It is showed that the deposit is controlled by fault structures and has close relation with metamorphosed marine volcanic rocks in early Jinning group.It has the characteristics of high copper,low sulfide and two periods metallogenic tem-peratures.The metallogenic fluids have experienced marine exhalation and structural magmatic fluids superimposi-tion.It is regarded that this copper deposit is marine -volcanic exhalative sedimentation and structural magmatic fluids superimposition type.
