The tasks for the reproduction of lead and zinc mineral base can be solved by performing prospecting
and forecasting-mineragenic research in order to strengthen the raw material base of operating enterprises in the old mining regions. Forecasting-mineragenic concepts are based on forecasting-prospecting models and forecasting-prospecting complex (FPC). In terms of its content, combination of methods and the order of its setting, the forecasting-prospecting complex is considered for two stages: I – forecastingmineragenic studies and II – prospecting for deposits. Compilation of a set of maps showing polymetallic mineralization distribution and forecast patterns, as provided by the FPC, includes the formation and analysis of a GIS maps package. The GIS package has a layer structure in which each thematic layer represents one or another property of the ore-hosting environment. Technology and methodological approaches based on forecasting-prospecting models and FPC were applied by TsNIGRI together with a number of other organizations in the implementation of basic Rosnedra projects in 2009–2017. These works made it possible to identify new deposits and estimate their inferred resources in Rudnoaltaiskaya, Priargunskaya, Salairskaya and Angara-Bolshepitskaya mineragenic zones (MZ), and justify preparation of areas for forecasting-mineragenic wors within the Ulugoyskaya MZ.
