An integrated application of high precision magnetic method and high frequency magnetotelluric method (EH4) was tested in the exploration of deposits in Tengchong lead-zinc poly-metaUic deposit and achieved a better prospecting result. This means the application of integrated geophysical methods in the positioning and prediction of deep or concealed ore bodies characterized by mutual supplement and mutual verification can improve the accuracy of geological interpretation, reduce the risk of project validation and accelerate the process of prospecting.
