The relevance of the research is conditioned by the necessity to improve survey efficiency in exploring non-ferrous and noble metal deposits in Kazakhastan ore fields. The main aim of the research is to analyze, to correlate and to interpret regional geological and geophysical data for determining pro- spective exploration areas of non-ferrous and noble metal deposits. Research methods: DSS (deep seismic sounding), observed G-field method of spectral and chemical analysis of core, loaming and channel samplings, as well as geological mapping involving scale 1:200000-10000. Research results. Kaskirkazgan-Karatassk ore area was identified based on the analysis, correlation and interpretation of regional ge- ological and geophysical data (scale 1:200000-1:50000), including ore mineralization indicators and characteristics. Kaskirkazgan-Kara- tassk ore area is located in the north-west of Pribalkhashe, close to the major juncture structures forming Atas-Zhongarsk median mas- sif. There are three large ore clusters within this area: (1) Kaskirkazgan-Auzbakensk (KA), (2) Konirat-Borlinsk (KB) and (3) Zhamantas- Karatassk (ZhK). Within the first cluster the ore fields of Kaskirkazgan-Kenkuduk-Kepcham-Auzbakensk deposits have been delineated; in the second area: Konirat-Karatas-Tortkolsk and Borlinsko-Zapadno-Borlinsko clusters, and in the third area: Sarikum-Zhamantas-ak- taysk and Karatas-Kokzaboy-Koskuduk-Minshunkursk clusters. More than 40 deposits and occurrences of copper, lead zinc, molybe- dum, wolframite and iron were found within this area. It was proven that special consideration should be focused on the exploration of granodiorite and granite-granodiorite massifs, which, in their turn, are allied with copper-porphyritic occurrences. Not only potential mi- neralization areas, but also areas of maximal occurrence of hydrothermal processes, from alkaline to ultra-felsic, as oxidized ore gos- sans were determined by geophysical and geochemical methods. The studied area embraces significant reserves of copper, poly-metals and other minerals, associated with upper mantle grade surface zones.
