５０５脉总体走向２７０～３１０°，呈透镜体状、扁豆状以尖灭再现或尖灭侧现的形式产出．５０５脉为一典型的具多金属硫化物含金石英脉．含金矿物主要是黄铁矿，其次为方铅矿和黄铜矿．黄铁绢英岩化是金矿化的重要标志．控矿构造有４次脉动，与其对应，５０５脉分４个成矿阶段，主要是Ⅰ、Ⅱ阶段及Ⅰ、Ⅱ、Ⅲ阶段叠加的部位成矿最好．５０５脉受一近东西向脆－韧性剪切带控制．矿体主要产于断裂的８５～９０°走向段和倾角为小于４５～５０°的缓倾段．这些部位也是多次矿化叠加、矿体厚度大、矿石品位高的部位，这些地段也是工业矿体产出的地段．
505 pulse to the overall 270 ~ 310 °, was lenticular, lentils to pinch off reproduction or pinch out the side of the form of output. The 505 pulse is a typical polymetallic sulphide-bearing quartz vein. The gold-bearing minerals are mainly pyrite, followed by galena and chalcopyrite. Yellowstone sericite is an important symbol of gold mineralization. The ore-controlling structure has four ripples, corresponding to them, with 505 pulses divided into four metallogenic stages, mainly in the stages I and II and in the superimposed parts of stages I, II and III. 505 pulse by a nearly east-west brittle - ductile shear zone control. The orebodies are mainly produced in the gently inclined section of 85 ~ 90 ° of fault and the inclination of less than 45 ~ 50 °. These sites are also superimposed mineralization, ore body thickness, high grade ore parts, these lots are also produced by industrial ore lots.
