The Baifang Copper Mine is located in the southern edge of the Hengyang Basin, where multiple structures are superimposed and composite. Folds, faults, unconformities, karst, and other factors in the area play an important controlling role in the formation and spatial distribution of the ore body. Deep exploration is difficult. Physical property tests have shown that there are significant differences in the electrical properties of rocks (minerals) from different strata in the area. The use of wide area electromagnetic methods can effectively analyze and predict geological characteristics such as rock development, structural morphology, fault distribution, and spatial distribution of rock masses. By implementing 7 wide area electromagnetic sounding profiles, conducting systematic processing and quantitative inversion calculations, the geological boundaries of the deep strata, structures, rock masses, and other geological bodies of the Baifang Copper Mine are inferred. Combined with the spatial positioning mechanism and laws of the ore body, the ore-forming geological body geophysical prospecting indicators are established to predict favorable ore-forming target areas. After verification by drilling engineering in the later stage, the results of the wide area electromagnetic method are in good agreement with the geological and structural development revealed by the engineering, providing sufficient geophysical basis for conducting edge and deep exploration.
