| description | The main aspects of perspectives and ways to create the gold mining industry of Ukraine as a source of replenishment of gold and foreign exchange reserves and an integral part of high-tech production have been considered. The latest EU trends in the mining industry, which have led to an increase of investment in geological exploration and, as a consequence, discovery and exploitation of new gold deposits, have been described. Brief information on the gold-bearing Archean-Proterozoic complexes of the world, which indicates a high concentration of deposits within the gold ore areas, has been given. The concentration of deposits is observed in zones of tectonic disturbance and metasomatic change of rock complexes, contrasting in composition. The geological characteristics of the most studied gold ore manifestations of the Ukrainian Shield (USh), where after additional studies it is possible to indicate industrial concentrations with significant increase of gold resources and start the production, have been presented. Similarities between USh manifestations and known Precambrian gold ore deposits of the world have been demonstrated. These are gold ore deposits of Precambrian green-stone belts and metamorphogenic-hydrothermal systems, so-called shear-zones of orogenic mesothermal type. Gold deposition is generally associated with sulfidization and associated quartzization and/or carbonation, the mineralization stage is preceded by albitization. Gold deposits were formed in several episodes over 2,1–1,8 billion years. Mostly native gold has a high proof quality, inherent associations with arsenic, tellurium and bismuth. The process of ore formation is multi-stage. The state of exploration and commercial attractiveness of USh gold ore objects for further works have been described by the example of the Maiske deposit. Methodological approaches to geological and economic assessment of gold ore objects have been considered. It has been demonstrated that determination of the gold content has been performed without taking into account the presence of gold particles of significant size and therefore its average content cannot be considered proven. Lack of information obtained during mining exploration leaves room for significant changes in the spatial and qualitative parameters of mineralization. Main unresolved problems, detected during researches, and ways to solve them have been outlined. Mining exploration of certain deposits will highlight the prospects of previously established gold ore areas. |
