Abstract

This study presents a methodology for constructing high-fidelity digital models of the Uchquloch polymetallic deposit using surface-based terrestrial laser scanning (TLS) combined with UAV photogrammetry. A Leica ScanStation P50 was employed, producing point-cloud datasets with a mean point spacing of 4 mm at distances up to 380 m. Point clouds were registered and classified using Leica Cyclone REGISTER 360 and CloudCompare; geological wireframes and block models were built in Leapfrog Geo 6.0 and Datamine Studio RM. Surface scanning achieves 3D model accuracy of ±12 cm RMSE, meeting JORC Code 2012 standards. Integration with drill-core data produced a 25×25×10 m block model of 187,400 blocks. Indicated resources stand at 4.82 Mt at 3.4% Pb+Zn, 0.21% Cu, 48 g/t Ag, and 0.8 g/t Au.
