In 1992 Cameco Corporation, formerly Centerra's largest shareholder was exploring for uranium and gold prospects in the Kyrgyz Republic, accepted an opportunity to follow up on a 1978 gold discovery at Kumtor that took place when the Kyrgyz Republic was part of the former Soviet Union. A final agreement for project development was concluded with the Kyrgyz Republic in 1994 under which Cameco acquired a one-third interest in the Kumtor Gold Company. Project construction began in late 1994 and commercial production in the second quarter of 1997. Since inception, the mine has produced between 300,000 and 750,000 ounces of gold annually.
