oa 3-D geochemical modelling of molybdenum mineralization at the East flank of Serhiivka complex Au-Mo deposit

Serhiivka is a complex Au-Mo deposit of Middle Dnipro granite-greenstone province of Ukrainian Shield, that is situated in the southern part of Sura greenstone belt. The Serhiivka deposit an be subdivided into two ore sites – Central Serhiivka with predominant gold mineralization and East Serhiivka that is characterized by predominant distribution of molybdenum mineralization. This paper discusses 3-D model created on the base of chemical and geochemical data available for the East flank of Serhiivka deposit. Dataset includes 137 boreholes, 12026 samples and 109314 analyses.

Mineralization patterns and distribution features of Mo, Au, Cu and Ag are studied with application of following software programs – Isatis (three-dimensional variogram analysis, three-dimensional geostatistics), ArcGis (mapping of two-dimensional data array, two-dimensional constructions) and EMS-I GMS (mapping of three-dimensional data array, three-dimensional geostatistics). In future, 3-D model created might be used for optimal location of exploration borehole grid and mine workings at subsequent stages of exploration and possible exploitation of Serhiivka complex Au-Mo deposit.
