Abstract:

In recent years，with the increasing of the depth of exploration，the traditional methods have not met the requirements of prospecting prediction.It is urgent to introduce new methods and technology.Xilaokou gold deposit is located in north margin of the Jiao-Lai basin，and has reached the large-scale now.For the five largest ore veins in mining area，only No.18 vein was systematically controlled by means of drilling engineering.And little of work has carried out for the other veins and its exploration and research level is relatively low.In order to predict deep orebody of this area, investigate ore-bearing properties of other ore veins and enlarge the scale of the deposit，CSAMT method is introduced.Through the analysis of CSAMT data，it provides the basis for drilling design.And the testing drilling results show that：the progress has been obtained in the deep prospecting of No.17 and 18 veins and confirmed that CSAMT method has a better application effect in Xilaokou gold prospecting，then，put forward the 18 vein and other veins as the focus of future prospecting work.Besides，the survey result shows a low resistively belt in the deep of No.17 and 18 veins.Combined with the regional geological background，we think that it is a larger shovel tectonic zone and has a better prospect for exploration.
