SUBSTANTIATION OF INVESTMENT IN STUDY AND IN-DUSTRIAL DEVELOPMENT OF THE “ZHYRYCHI” COP-PER ORE OCCURRENCE IN VOLYN

English abstract

The stratiform deposits of native copper were found among the trap complexes of the lower Wend In the cover of the Volyno-Podilskiy Plate of the Volyn territory in the southwestern part of the East European Platform. They corresponding to the larg-est mineralogical provinces of the World by resources. In the article economical efficiency of the copper deposits geological study and industrial development of the Volynian Vendian traprocks are substantiated by ex-ample of the “Zhyrychi” ore occurrence. The ore occurrence’s general characteristics, information about copper-bearing horizons, ores and ore bodies and project data of its prospecting are given. Technical and economical indicators of its industrial development were identified. An approach to the complex processing of copper basalt and basalt tuffs, which involves the ex-traction from them, in addition to copper, and precious metals, as well as the use of enrichment tails as a peturgical raw material. The current market value of metallurgical copper averages $ 5,000 per ton. Considering that, possible income from development of the copper deposits may amount several billion $ from each ones. The conclusion is that the biggest income will be obtained if 0.2% cut-off grade ores be used, and the highest profitability – at 0.4% cut-off grade. The obtained results may become a basis for further geological-economical re-searches of the other numerous ore occurrences in the Volynian traprocks. In total, they delineate a large copper-bearing province of European significance.
