Abstract. This study presents an in-depth geospatial and geodetic analysis of the Tulallar gold deposit using modern 3D modeling techniques. A dataset of 152 exploratory boreholes, totaling 17,705.55 meters in depth, served as the foundation for a detailed three-dimensional model developed in Golden Software Surfer. The research aimed to visualize the spatial distribution of gold-bearing ores and quantify the variability in gold concentrations at different depths and across various geological zones.

Advanced GIS tools, including the Drillhole module and Kriging interpolation method, were applied to accurately depict subsurface mineralization. The analysis revealed pronounced zoning, particularly in the southwestern sector, where gold concentrations reached up to 7.5 g/t, compared to lower values in the central and northern parts of the deposit. The addition of topographic layers, isosurfaces, and contour mapping allowed dynamic interpretation of ore body morphology, zoning, and depth distribution.

The constructed 3D models enabled not only the identification of economically viable mineral zones but also the visualization of their spatial configuration with a high degree of accuracy. Such models allow geologists to assess the relationship between ore concentration and terrain elevation, facilitating more strategic decisions in exploration and mining planning.

This integrated geodetic and GIS-based approach proved to be effective for visualizing the geometry of economically viable mineralized zones. The results confirm that the southern zone holds the highest potential for future exploitation, with implications for more precise resource estimation, optimized mining strategies, and environmentally sustainable planning. The conducted analysis demonstrated that gold concentrations in the southwestern part of the study area significantly exceed those observed in the central and northern zones.

Thus, by varying both elevation and concentration data, it is possible to perform a comprehensive and accurate analysis of the deposit. This approach not only enables the identification of optimal depths for mining, but also provides a rational basis for selecting appropriate extraction technologies. The resulting data form a solid foundation for reliable resource estimation and strategic planning of deposit exploitation.
