内蒙古布航特位于内蒙古东乌旗-大兴安岭北段Cu-Mo-Pb-Zn-Ag-Au-Ni-Cr-Co三级成矿带上。1∶5万土壤测量显示，土壤中Ag、Pb、Zn等中低温元素异常呈半环带状围绕Sn、W、Mo高温元素异常分布，异常强度高，组分分带明显，异常查证中圈出的1∶1万土壤异常分布与其类似，异常强度更高，Pb、Zn、Ag异常浓集中心指示了浅覆盖铅锌矿体位置。与土壤异常对应的低阻高极化率圆形面状异常，指示有隐伏极化体存在，推测深部存在隐伏花岗斑岩体；隐伏岩体及其内、外接触带深部找矿潜力较大。以斑岩成矿理论为指导，进一步发现了多条浅覆盖铅锌矿体和隐伏银矿体、钼矿体，总结了本区地质、物探、化探找矿标志。

Along the third grade Cu-Mo-Pb-Zn-Ag-Au-Ni-Cr-Co metallogenic belt in Dong Ujimqin Banner-northern Da Hinggan Mountains region of Inner Mongolia, 1 ∶ 50,000 soil survey has revealed that there exist Ag, Pb and Zn mesothermal-epithermal ele-ment anomalies which are distributed in the semi-ring form around high-temperature elements Sn, W and Mo. The anomalies have high intensity and obvious compositional zoning. The 1 ∶ 10,000 soil anomalies delineated by anomaly verification are distributed similar to the above anomalies, but with higher intensity;the concentration centers of Pb, Zn and Ag anomalies indicate the locations of the shal-lowly-covered Pb-Zn orebodies. The low-resistivity and high-polarizability circular planar anomalies corresponding to the soil anomalies indicate the existence of polarized bodies. It is inferred that there exists a concealed granite-porphyry body in the depth, and this rock body as well as the depth of its endo-and exo-contact zones has fairly promising prospecting potential. Guided by the porphyry metallo-genic theory, the authors further found a number of shallowly-covered lead-zinc orebodies, concealed silver orebodies and molybdenum orebodies, and summarized the geological, geophysical and geochemical indicators in search for ore deposits.
