As one of the most important gold provinces in China, the Northwest Jiaodong gold province is charac⁃terized by highly concentrated gold resources and complex metallogenic processes. The Hongbu Gold Deposit is a typicalrepresentative within this area. In recent years, with continuous mining activities, shallow orebodies have graduallybecome depleted, creating an urgent need to extend the mine’s service life through innovations in metallogenic theoryand advancements in exploration technology. By integrating multi⁃source geological data and applying implicit modelingtechniques, a 3D geological model of the Hongbu Gold Deposit was established. Based on this model, the ore⁃formingprocess was numerically simulated through conceptual modeling, numerical modeling, and simulation design. Theresults suggest that the deep part and peripherals in the northwest of the Hongbu Gold Deposit show certain metallogenicpotential. The duration of a single mineralization event does not exceed 2 500 a, which provides constraints on themetallogenic timescale. This research can effectively reduce exploration costs, clarify future exploration directions, andoffer guidance for identifying substitute resources in similar deposits.
