We utilized N-S, C-V and S-V fractal models to delineate different grades of mineralization in the Pulang deposit. The high-grade mineralization determined by S–V has a better correlation with potassic alteration zones resulting from the 3-D geological model than from N-S and C-V models. The highly and moderately mineralized zones obtained from the fractal models are both situated in the southern and central parts of the Pulang deposit and coincide with potassic and phyllic alteration zones.
