The Halashan lead-zinc deposit contains high-Zn ore with high oxidation. The altitude of the ore field is above 4 300 m. The ore bodies are controlled by the secondary structures of the major fault belt. The rocks in the deposit are lithologically simple. The electrical features of the ore bodies are different from those of the wallrocks. By measurement of frequency-domain induced polarization method, small-amplitude low-gradient anomalies of frequency (Fs) are delineated. Analysis shows that they are anomalies related to mineralization.
