NEWS RELEASE

Centerra Gold Seeks Urgent Relief in International Arbitration to Prevent the Kyrgyz

Republic from Destroying the Integrity, Value and Long-Term Viability of the Kumtor

Mine

Kyrgyz Government’s Actions Jeopardize Mine’s Safety, Sustainability and Continued

Operation

Toronto, Canada, September 27, 2021: Centerra Gold Inc. (“Centerra” or the “Company”)

(TSX: CG) (NYSE: CGAU) announced today that it has filed an application requesting urgent

interim measures in its international arbitration against the government of the Kyrgyz Republic

and Kyrgyzaltyn JSC, the state-owned gold refining monopoly and Centerra’s largest

shareholder, to address critical operational and safety problems at the Kumtor Mine.

Through this application, Centerra seeks to prevent the Kyrgyz Republic and Kyrgyzaltyn JSC

from causing irreparable damage to the mine, destroying its integrity, value and long-term

viability. As previously disclosed, Centerra initiated binding arbitration against the Kyrgyz

government in response to actions taken against the Company’s wholly owned subsidiary

Kumtor Gold Company (“KGC”), to expropriate the Kumtor Mine under the guise of “external

management” and strip KGC of its assets.

Dan Desjardins, the Chief Operating Officer of Centerra who managed the Kumtor Mine for five

years as the President of KGC until January 2020, said: “Statements by Kyrgyz officials since

the government’s illegal seizure of the Kumtor Mine indicate that they are departing from the

approved mine plan in ways that will cause irreversible damage. Based on recent reports, the

government has also failed to adequately protect the mine’s infrastructure from flooding and

other threats and may be facing production difficulties. Their actions, and threatened actions in

pursuit of short-term profits at the expense of sustainability, place the long-term viability of the

Kumtor Mine at grave risk and compromise the safety and livelihoods of its employees.”

Centerra seeks the following immediate relief pending a final award in the arbitration:

• An order directing the Kyrgyz Republic to refrain from deviating from the government-

approved 2021 Kumtor Mine Plan and to provide Centerra with regular reports on the

mine’s operations;

• An order directing the Kyrgyz Republic and Kyrgyzaltyn JSC to refrain from

transferring any Centerra shares or KGC assets without a prompt accounting and

payment of profits that otherwise would have been payable to the Company into an

escrow account; and

• An order directing the Kyrgyz Republic and Kyrgyzaltyn JSC to refrain from interfering

with the arbitration process, including through spurious fines, tax claims and legal

proceedings, and intimidating or threatening Centerra’s employees and agents.

Under applicable investment agreements, Centerra’s claims will be adjudicated in arbitration

proceedings to be held in Stockholm, Sweden and conducted under the rules of the United

Nations Commission on International Trade Law (“UNCITRAL”). The Permanent Court of

Arbitration (“PCA”) has appointed The Rt. Hon. Lord Hoffmann as the sole arbitrator of the

matters in dispute and the governing law of the arbitration is the law of the State of New York

and of England.

Centerra’s application states that the Kyrgyz government and its agents are jeopardizing the

Kumtor Mine itself and Centerra’s ability to receive any award at the conclusion of the

arbitration as a result of the following egregious acts of mismanagement:

• Maximizing Short-Term Output in Pursuit of a Quick Profit Will Reduce the Life of

the Mine

For more than 20 years, Centerra, through KGC, successfully operated the Kumtor Mine by

following carefully designed mine plans that had been approved by successive governments of

the Kyrgyz Republic. Since the government seized the mine on the weekend of May 15 and 16

2021, the government-appointed mine managers appear to be departing from the mine plan,

apparently to extract quick profits by mining only high-grade ore. This could make it infeasible

to obtain the full value of the gold from the mine, materially reducing the total output over the

life of the mine. Prior to the mine’s illegal seizure, Centerra had planned to invest US$2 billion

to extend the life of the mine by five years to 2031.

• Improper Operation of Specialized Water Pumps Could Destabilize and Collapse the

Pit Wall

Beginning in about 2015, as the pit depth increased, Centerra management invested more than

US$10 million to build a highly specialized pump system to keep glacial meltwater from

entering the mining pit areas and similarly specialized pump systems to remove any water that

enters the pit. Based on photographic evidence, the government-imposed management does not

appear to be operating those pumps effectively. Large amounts of water can be seen streaming

down the walls of the mine and glacial meltwater is accumulating in the bottom of the pit well

beyond normal levels. The mine cannot operate effectively if water collects at the bottom of the

pit, because that is where the highest-grade ore is mined. Allowing large amounts of glacial

meltwater to flow down the pit walls also destabilizes the walls and can cause them to collapse.

• Transitioning to Underground Mining Risks Irreversible Damage

The Kyrgyz government-appointed external management has publicly stated that it plans to

reconfigure the Kumtor Mine from an open pit to an underground mine. KGC previously

engaged a mining contractor to study and develop underground mining at the site, and after

extensive work, the company determined that it was not geologically and economically viable.

The pursuit of an underground mining plan risks causing irreversible damage to Centerra’s

longstanding investment in the open pit mine.
