FORECAST OF PLANITOMETALLIC MINERALIZATION IN BLACK SHALE DEPOSITS IN THE EASTERN PART OF KAZAKHSTAN
Three areas have been identified as promising areas for the PGM in the eastern part of Kazakhstan. Of greatest interest is the West Kalba gold belt. Four types of platinum ore mineralization are possible within it: 1) complex gold-platinoid deposits in black shale; 2) actually platinoid deposits in black shale; 3) platinoid mineralization in connection with arrays of hyperbasites; 4) coal deposits, which are located in the zones of demolition of the denuded parts of gold-platinum ore objects. The Kungei ore area in the northeastern part of the Jungar Alatau is composed of marine sedimentary rocks in which carbonaceous shales are developed. They almost always contain elevated levels of gold and PGM, especially in the places where they are propilitized and pyritized. The Koksu-Tekeli ore district is a large shungite province. The contents of gold and PGM in them reach industrial values. Further study and evaluation of ore objects is complicated by the lack of reliable analytical methods for the determination of precious metals. It is proposed to organize an experimental-methodical group to develop a method of analysis and technology for the extraction of precious metals
