As part of a new restructuring and investment agreement the Government of the Kyrgyz Republic, effective June 2004, under which tax and legal rules governing the Kumtor project were finalized, both Cameco (66%) and Kyrgyz Republic-owned Kyrgyzaltyn JSC (33%) transferred their interests in the Kumtor mine to Centerra, with outstanding debts owed to the International Finance Corporation and the European Bank for Reconstruction and Development exchanged for a 4% interest in the new company.

Both countries were relatively new to foreign direct investment, with Kumtor making up 4% of the Kyrgyz Republic's gross domestic product in 2007[3] and Boroo accounting for almost 10% of Mongolia's GDP in 2004,[4] and consequently subject to an evolving legal environment.

While Centerra had negotiated legally-binding investment agreements for both projects to provide a regulatory framework and certainty in financial obligations, conflicts did continue to arise to which the company had to respond.

Kumtor was subject to nationalization debates and the agreement was reviewed after both the 2005 and 2010 revolutions,[5][6][7] while Mongolia adopted new mining tax and environmental protection laws that threatened the viability of Boroo and Centerra's developing Gatsuurt property.

[21] Political instability in Kyrgyzstan following the October 2020 elections and the ensuing protests, referendum to switch from a parliamentary system of government to a presidential system, and then the election of nationalist Sadyr Japarov as president, led to a law being adopted that allowed Kyrgyzstan to temporarily operate the Kumtor Gold Mine for 3 months for the purposes of rectifying alleged dangers to people and the natural environment.

Former Prime Minister Ömürbek Babanov and other officials came under investigation of financial crimes related to Kumtor[23] and Centerra sued its former board member Tengiz Bolturuk alleging that he assisted the expropriation.

The Endako mine is located in northern British Columbia, Canada, near Fraser Lake, and is operated as a joint venture with the Japanese company Sojitz Corporation which has a 25% interest.

It is a conventional open-pit mine with an on-site mill where doré bars are produced from ore that is ground, dissolved into a pyrite flotation, sent through a carbon in leach system and collected by electrowinning.

Prior to 2004 Centerra, through parent company Cameco, held partial interest in the Boroo project and jointly conducted exploration and development work with AGR.

The mine had reached commercial production in February 2004 and produced approximately 50,000 to 90,000 ounces of gold ore per year until extraction activities ended in 2014, though processing of remaining material continued into 2015.
