为了解决寨上矿区王足路矿段地表第四系及新近系覆盖厚造成找矿难度较大的问题，通过引进可控源音频大地电磁测量等技术手段，在王足路矿段布设了3条线（188线、196线、204线）圈定异常，并结合野外地质调查，进行了解译，大致确定寨上矿段内的含金破碎带向西延伸至王足路矿段。经钻孔验证，基本确定寨上矿段的9号和10号矿脉延伸至王足路矿段188线，并且在深部探矿工程中发现有石英闪长玢岩脉，说明王足路矿段成矿物质来源于深部，成矿潜力巨大。实践证明，借助可控源大地音频电磁测量圈定异常、再经深部钻探验证寻找矿化体的勘查模式，在西秦岭西段厚覆盖区的找矿效果显著。

In order to solve the great difficulties in exploration with surface covered by the Quaternary and Neogene period at the Wangzulu ore block，three lines （line 188，196 and 204） was laid in the study area for anomaly delineationthrough introducing technology of controllable source audio-frequency magnetotelluric measurements.Combined with field geological survey，we interpreted the findings and roughly determined that the broken zone with gold presented a western trend until the Wangzulu ore block at the Zhaishang gold ore.It has been verified by drilling that No.9 and No.10 mineral vein of the Zhaishangore block almost extended to line 188 of the Wangzulu ore block.Additionally，quartz diorite bin vein was discovered in process of deep prospecting engineering，indicating that the ore-forming materials at the Wangzlu ore block mainly originated from the deep，and that showed the tremendous metallogenic potential.Practice demonstrated that，with the aid of controllable source audio frequency electromagnetic measurement for anomaly delineation，and with verification by deep drilling prospecting model in search of mineralized bodies，remarkable prospecting effect was obtained in the thickly-covered region of the western Qinling.
