Abstract The Wudaogou area, located in the juncture of Xing'an massif and Songnen massif and the eastern part of Duobaoshan ore-concentrated area, has favorable metallogenic geologic conditions. The geochemical prospecting method plays an important role in the mineral survey in this forest-covered area. The regional geological and geochemical explorations and soil surveys in key areas are carried out hierarchically to determine the major minerals and delineate the key prospecting targets, which have obtained certain results. Two copper occurrences, two gold mineralization spots, ten gold (copper) mineralization information sites, and three prospecting clues are newly discovered through anomaly verification. Three Level-I and two Level-II prospecting targets are also delineated. By study on the distribution of elements, combined with metallogenic geologic background analysis, it is thought that there is local enrichment of elements such as Au, Ag, Cu and Pb, among which Au and Cu have great metallogenic probability. The mineralization is closely related to Mesozoic magmatism.
