Lashuixia ore deposit is one of the most important Cu-Ni deposits in Qinghai Province. It has particular geological background and mining environment. Based on the study of the electro-geochemical, low resistant and high magnetic anomalies feature, the authors conclude a comprehensive exploring model combining with the geophysical and electro-geochemical exploring methods, and prospect concealed ore using the model in mining. Finaly, four abnormal targets were found in external and deeper areas of the deposits by geo-electrochemistry methods, which provide the evidence for further surveying and geological work.
