Abstract A study of geochemical tracing for the anomaly source of Pt and Pd in stream sediments shows that the Pt and Pd source in some stream sediment samples is derived from the weathering products of the nickel ore. A nickel orebody 130 m wide and 325 m long at surface with nickel content of 0.23% and highest Pt and Pd grade of 0.4g/t was discovered based on the data obtained from the soil and rock survey. Prediction of Pt, Pd and Ni potentials was made for Dacao area.
