Abstract: To carry out deep prospecting for the Xiagalaiaoyihe lead-zinc polymetallic deposit， three-dimensional geological modeling of the deep strata and ore bodies was conducted using Micromine software， based on geological and ore geological data of the mining area， and achieved three-dimensional visualization and transparency of the deep geological bodies. The cubic prediction model and prospecting information quantity method were used to statistically analyze multi-source geological data in the mining area. Finally， 3 lead-zinc mineralization target areas and 4 magnetite mineralization target areas were delineated within the mining area， providing reference and basis for future prospecting work.
