Remote sensing mapping and 3D modelling of Petelovo Au-epithermal system, Panagyurishte ore district, Bulgaria

Remote sensing drone-based study combined with field mapping, XRD and XRF tests for mineral detection outlined advanced argillic, argillic and propylitic alteration domains within the Petelovo silica cap to demonstrate quick approach for mineral alteration mapping. Mineral alteration modelling by 3D Leapfrog Geo outlined zonal patterns around epithermal high-sulphidation Cu-Au mineralization could be employed as a pathfinder for gold enrichment.
