In the mountains area, we have to solve the problem that how to select appropriate method, accurately and effectively explore the burial condition and location of the deep mineral ore with complex terrain. Advanced and Convenient high-frequency magnetotelluric (HF-MT) sounding system Stratagem EH- 4 was applied to electromagnetic array profile survey in target mining area of northern Guangxi. Bostick and Rapid Relaxation Iterative inversion method were used to interpret the observational data, and it has been verified by the mine works that location of faults and orebodies marked by resulting images are tally with the real geological conditions, which provide resource base for the continued production of the mine. This measurement technique and interpretation method should be popularized and applied in mineral resources exploration, especially in mountains area.
