Abstract To examine the actual result of the electricmagnetic method in detecting deep metallic ore deposits and structures,
the authors conducted two tests in two known buried iron and copper ore deposits by using Controlled Source Audiofrequency
Magnetotelluric Method (CSAMT). The two known ore bodies have the buried depths of about 500 m and 1 100 m, respectively. The
results of the tests show that the geoelectrical anomalies can indicate the distribution of ore bodies, faults and lithologic
contact zones. When the buried depth of the ore body is less than 500 m and the ore bed is relatively thick, the geoelectrical
anomaly is very obvious. When the buried depth of the ore body is more than 1 000 m, the geoelectrical anomaly mainly reflects
the orecontrolling and orehosting structure.
