Kazakhstan is the second country in the world in terms of reserves and resources of uranium. According to the IAEA, reserves and resources of uranium in Kazakhstan is currently about 1.7 mln. tons, or about 12% of total world reserves and resources of uranium.
The first commercial deposit in the country (Korday) was explored in 1951. The most important discoveries were made later. In the late 60s, it was explored uranium in province of Shu-Sarysu and Ili in southern Kazakhstan, which became the world's largest reserves of uranium ores.
With these discoveries, Kazakhstan has become a world leader in explored uranium reserves, suitable for practicing the method of in-situ leaching.
Deposits of uranium, discovered on the territory of Kazakhstan, are different in terms of form and practical value. In common geological positions, genetic traits and territorial isolation, deposits in Kazakhstan can be considered as part of the six uranium ore provinces: Shu-Sarysu, Syrdariya, North Kazakhstan, the Caspian, Balkhash, Ili.
Currently, 16 deposits out
of 54 explored ones are in use,
the remaining 38 are on standby.
The peculiarity of uranium in Kazakhstan is that about 80% of them are concentrated in fields such as sandstone, which allows the extraction technology of in-situ leaching.
JSC "Volkovgeology", which is the successor of Volkovskaya geological expedition, that opened Kordai field, provides geological ensuring for all activities of Kazatomprom and conducts technological drilling of mining and preparatory work on the uranium mining enterprises of the Company.
