Commentary

Scott Perry, President and Chief Executive Officer of Centerra stated, "During the first quarter we continued to demonstrate positive safety performance as the Kumtor mine achieved one-year lost time injury free and Endako achieved six years reportable injury free. Across the organization we continue to stay vigilant with respect to the COVID-19 virus, proactively maintaining our rigorous safety protocols to prevent an outbreak and reduce the spread of the COVID-19 virus for the health and safety of our employees, contractors, communities and other stakeholders."

"In the first quarter, our three operating mines continued to deliver solid performances, including the Mount Milligan mine which generated record quarterly free cash flow. Company-wide our operations in the quarter delivered gold production of 160,346 ounces at all-in sustaining costs^NG on a by-product basis of $745 per ounce. The Mount Milligan mine produced 42,576 ounces of gold and 18.6 million pounds of copper at all-in sustaining costs^NG on a by-product basis of $367 per ounce, making it our lowest cost producer in the quarter. The Kumtor mine produced 90,169 ounces of gold at all-in sustaining costs^NG on a by-product basis of $888 per ounce and the ?ks?t mine produced 27,601 ounces of gold at all-in sustaining costs^NG on a by-product basis of $804 per ounce as it now enters its first full year of commercial production."

"Financially, the Company generated $153.1 million of cash from operations for the first three months of 2021, which includes $89.7 million from the Mount Milligan mine, $66.7 million from the Kumtor mine and $32 million from the ?ks?t mine. Company-wide free cash flow^NG generated in the first quarter of 2021 totalled $72.1 million, including $80.2 million from the Mount Milligan mine, $25.7 million from the ?ks?t mine and $4 million from the Kumtor mine. With the proceeds of the disposition of the Greenstone property, we finished the quarter with a cash position of $823.2 million."

"Based on the Company's financial position, strong operating results and cash flows, the Board approved on May 10, 2021, a quarterly dividend of CAD$0.05 per share."

"The Company notes that there is a great deal of uncertainty regarding future production and operations at the Kumtor Mine due to recent legislative changes in the Kyrgyz Republic relating to the Kumtor Mine. Accordingly, the 2021 guidance and previously disclosed 3-year outlook should be viewed with caution. We remain on track to achieve 2021 production and cost guidance at our Mount Milligan and ?ks?t mines, and the Company is expected to generate $160 million (guidance midpoint) in free cashflow, excluding the Kumtor Mine."

"The Company remains committed to trying to work with Kyrgyz Republic authorities to resolve these issues in accordance with the 2009 restated project agreements applicable to the Kumtor Mine, if the authorities are willing to do so. However, the Company will also use all legal avenues to defend itself against baseless environmental and tax cases in the Kyrgyz Republic as well against legislative changes that not only violate but fundamentally undermine the terms of the 2009 restated project agreements."

"Recently, the Company successfully listed and commenced trading on the New York Stock Exchange to increase the Company's visibility and exposure to investors in the United States."

Kyrgyz Republic Update

As previously disclosed, the Kyrgyz Republic Parliament passed a law on May 6, 2021 which would enable the Kyrgyz Republic Government to impose "external management" on companies in the Kyrgyz Republic operating under concession agreements. The sponsor of the law, Mr. Akylbek Japarov, has acknowledged that the only project operating under a concession agreement in the Kyrgyz Republic is the Kumtor Mine and therefore this new law purports to regulate only the Kumtor Project. The Company understands that this newly adopted law on external management would apply in circumstances where Kumtor Gold Company (KGC) violates certain Kyrgyz laws relating to safety and thereby creates an immediate threat to the life or health of people. In such instances, the law would (i) enable the Prime Minister of the Kyrgyz Republic to appoint an external manager to take control of all management activities of KGC, including its bank accounts, and (ii) prohibit the Company or KGC's board of directors from directing the external managers (or else face criminal sanctions).

Mr. A. Japarov is also the Chairman of the Kyrgyz Republic State Commission which was formed in February 2021 to review the activities of the Kumtor Mine and is expected to report its findings shortly.

The Company is also aware of other draft laws and decrees in the Kyrgyz Republic which seek to undermine the 2009 restated Kumtor project agreements and the tax and fiscal regime under which the Kumtor Mine has operated since 2009. It is unclear whether such drafts have progressed past the proposal stage.

On May 7, 2021, a Kyrgyz Republic court ruled against KGC in a case brought by four Kyrgyz Republic private citizens seeking a determination that KGC's past practice of placing waste rock on glaciers was illegal. The court awarded damages of over U.S.$3 billion in favour of the Kyrgyz Republic. The Company notes that one of the claimants is the son of the current Director of the Kyrgyz Republic State Agency for Environment Protection and Forestry.

The Company has also received further tax assessments from the Kyrgyz Republic State Tax Service which when, combined with previous tax claims, amount to hundreds of millions of dollars.

As the Company has noted many times, the 2009 restated Kumtor project agreements provide a solid foundation for Kumtor's operations and were approved by the Kyrgyz Republic Parliament and Constitutional Court in 2009. Those agreements were re-affirmed by the Government of the Kyrgyz Republic in 2017 when it entered into the Strategic Agreement on Environmental Protection and Investment Promotion which was completed and became fully effective in 2019. KGC's operations and activities have always carefully adhered to those agreements and applicable laws. Furthermore, the Strategic Agreement included a release of the Company and KGC by the Kyrgyz Republic Government of all outstanding claims at such time, including damages for harm allegedly caused to the environment from storing production tails on glaciers. The Company therefore believes strongly that the claims advanced by the State Tax Service and such individual Kyrgyz Republic claimants are meritless and the new and draft Kyrgyz Republic laws noted above, if implemented, would clearly violate the 2009 restated project agreements and the 2009 Kyrgyz Republic laws which confirmed such agreements. The Kumtor Mine's environmental performance adheres to international standards, including those of the European Bank for Reconstruction and Development, and has been audited multiple times by, among others, the Kyrgyz Government's own environmental consultant, AMEC Foster Wheeler. AMEC's reports have confirmed that the Kumtor Mine is operated in accordance with international best practice and its recommendations for improvements have been fully implemented by the Company in a manner agreed by the Kyrgyz Government in the 2017 Strategic Agreement. In terms of Kumtor's safety record, the mine recently achieved, one year of operations free of any lost time injuries.

The Company believes that the actions of the Kyrgyz Republic authorities described above are a concerted effort to coerce Centerra to give up economic value or ownership of the Kumtor Mine or to falsely justify a nationalization of the Kumtor Mine. While the Company has benefited from a close and constructive dialogue with the Kyrgyz Republic authorities over many years and remains committed to trying to work with them to resolve any outstanding issues in accordance with the 2009 Restated Project Agreements applicable to the Kumtor Mine, it will not hesitate to use all legal avenues to protect its rights and interests and those of its shareholders and it intends to pursue its claim in international arbitration proceedings.

No assurances can be given that any of the current or future legal claims of the State Tax Service or individual claimants, disputes as to the application of current or future Kyrgyz Republic laws relating to the Kumtor Mine, the results of the State Commission review or any other future regulatory, civil or criminal claims impacting KGC or Centerra can be resolved without a material impact on the Company. See "Contingencies" for further information relating to these Kyrgyz Republic developments.

COVID-19 Update

Centerra continues to prioritize the health, safety and well-being of its employees, contractors, communities, and other stakeholders during the current outbreak of COVID-19 and to take steps to minimize the effect of the pandemic on its business. The Company has established strict COVID-19 protocols at its mine sites to help prevent infection and reduce the potential transmission of COVID-19. In addition, operating mine sites continue to assess the resiliency of their supply chains, maintaining increased mine site inventories of key materials. The Company has also implemented travel restrictions and has temporarily closed or limited office capacity at its various administration offices including its head office in Toronto.

In Turkey and the Kyrgyz Republic, the week-over-week status appears to be stabilizing, with the national daily COVID-19 case count in Turkey at approximately 25,000 (down from a high of 65,000 in recent weeks) and the national COVID-19 daily case count in the Kyrgyz Republic holding at approximately 300 cases per day. At the ?ks?t mine, 17 individuals are in quarantine, primarily from the mine's open pit mining contractor. The Turkish Government has declared a nine-day public holiday & stay-at-home period for the post Ramadan celebration in May 2021, during which blasting activities in the open pit at the ?ks?t mine will be halted, resulting in a net two to three days of no mining activity. In the Prince George region of British Columbia, Canada, near the Mount Milligan mine, daily COVID-19 case counts at approximately 150, (down from a high of approximately 200 in recent weeks). As part of the roll-out of vaccinations across Northern British Columbia, COVID-19 vaccinations were made available to Mount Milligan employees in April 2021. The majority of the Molybdenum Business Unit is located in the United States have not been materially affected by COVID-19 due, in part, to a rapid COVID-19 vaccination roll-out.

COVID-19 has not materially affected Centerra's operations as employee absences due to COVID-19 and other illnesses have so far been successfully managed. The Company notes that the effects of COVID-19 on its business continue to change rapidly. The measures enacted to date reflect the Company's best assessment at this time but will remain flexible and be revised as necessary or advisable and/or as recommended by the public health and governmental authorities.

Exploration Update

Exploration activities in the first quarter of 2021 included drilling, surface sampling, geological mapping and geophysical surveying at the Company's various projects and earn-in properties, targeting gold and copper mineralization in Canada, Turkey, Finland, USA and the Kyrgyz Republic.

Exploration expenditures were $9.3 million in the first quarter of 2021 compared to $7.8 million in the same quarter of 2020. The increase in exploration expenditures was due to a significantly expanded drilling program at the Kumtor mine, drilling approximately 20,000 metres in the first quarter of 2021, as well as the recommencement of drilling activities at ?ks?t and Mount Milligan earlier in than the prior period.

Selected drill program results and intercepts are highlighted in the supplementary data at the end of this news release. The drill collar locations and associated graphics are available at the following link: http://ml.globenewswire.com/Resource/Download/ebc019dc-6dc1-46a5-a948-2fde2391fd4f

Consolidated Financial and Operational Highlights

Overview of Consolidated Results

First Quarter 2021 compared to First Quarter 2020
Net earnings of $167.4 million were recognized in the first quarter of 2021, compared to net earnings of $20 million in the first quarter of 2020. The increase in net earnings was due to the increase in ounces of gold sold at the ?ks?t and Mount Milligan mines, a 9% higher average realized gold price, and a 69% higher average realized copper price, compared to the same prior year period, as well as a gain of $72.3 million in the current quarter, on the sale of Centerra's 50% interest in the Greenstone Gold Mines Partnership, partially offset by less gold ounces sold at the Kumtor mine.

Adjusted net earnings^NG in the first quarter of 2021 was $84.2 million after adjusting for the $72.3 million gain on the sale of Centerra's 50% interest in the Greenstone Gold Mines Partnership and the $10.9 million gain resulting from the reduction in the reclamation liability due to favourable discount rate movements. Adjusted net earnings^NG in the first quarter of 2020 was $46.4 million, after adjusting for the $26.4 million charge resulting from the increase in the reclamation liability due to unfavourable discount rate movements.

Cash provided by operations was $153.1 million in the first quarter of 2021, compared to $121.1 million in the first quarter of 2020. The increase in cash provided by operations was due to increased earnings from mine operations at the ?ks?t mine which recorded a full quarter of operations and the Mount Milligan mine which recognized its highest quarterly cash from mine operations since it commenced production. The comparative first quarter of 2020 included the receipt of a tax refund of $11.4 million collected at the molybdenum business unit.

Free cash flow^NG of $72.1 million was recognized in the first quarter of 2021, compared to $77 million in the first quarter of 2020. The decrease in free cash flow^NG was due to higher capital expenditures including the purchase of haul trucks for the life of mine extension at the Kumtor mine and major planned equipment rebuilds at the Mount Milligan mine, partially offset by higher cash provided by operations.

Safety and Environment
During the first quarter of 2021, the Kumtor mine achieved one-year lost time injury free, and the Endako mine achieved six years reportable injury free. In addition, Centerra experienced zero reportable injuries and zero significant incidents Company-wide in the month of March 2021.

There were four reportable injuries company-wide in the first quarter of 2021, including one lost time injury, two medical aid injuries and one restricted work injury.

Centerra has implemented a number of proactive measures to prevent infection and reduce the spread of COVID-19 for the health and safety of its employees, contractors, communities and other stakeholders.

There were no reportable incidents to the environment in the first quarter of 2021.

Outlook

The Company notes that there is a great deal of uncertainty regarding future production and operations at the Kumtor Mine due to recent legislative changes in the Kyrgyz Republic, public rhetoric regarding nationalization, and tax and legal claims and investigations relating to the Kumtor Mine. Accordingly, the following 2021 guidance and previously disclosed 3-year outlook should be viewed with caution and may be materially different as a result of the foregoing and similar matters. For further information, please refer to "Caution Regarding Forward-Looking Information" and "Contingencies".

2021 Production Guidance
Centerra's 2021 consolidated gold production guidance remains unchanged and is expected to be between 740,000 to 820,000 ounces. Production from the Kumtor, Mount Milligan and ?ks?t mines is expected to be weighted to the second half of the year, representing up to 60% of 2021 annual gold production. ?ks?t's second quarter production volumes are expected to represent 15% of its 2021 annual gold production due to the sequencing of lower-grade ore onto the leach pad, with meaningfully higher-grade ore stacking expected in the second half of the year.

Centerra's 2021 production forecast is unchanged from previous guidance and is as follows:

2021 Sales, All-in Sustaining and All-in Unit Costs Guidance^NG
Centerra's 2021 sales and cost metrics are unchanged from the previous guidance and are as follows:

2021 Taxes
In April 2021, the Government of Turkey enacted a corporate tax rate increase from 20% to 25% for 2021. As a result of the tax benefits available under the Company's Investment Incentive Certificate, income tax in 2021 for the ?ks?t mine is expected to be unchanged from previous guidance of between $1 to $2 million.

2021 Sensitivities
Centerra's revenues, earnings, and cash flows for 2021 are sensitive to changes in certain key inputs or currencies. The Company has estimated the impact of any such changes on revenues, net earnings, and cash flows for the remaining nine months of 2021 as follows:

  • $1USD:7.50 Turkish lira.
• diesel fuel price assumption:
  • $0.44/litre at Kumtor,
  • $0.69/litre (CAD$0.90/litre) at Mount Milligan.

Kumtor Fuel
The assumed diesel price of $0.44/litre at the Kumtor mine assumes that no Russian export duty will be paid on the fuel exports from Russia to the Kyrgyz Republic. Diesel fuel for the Kumtor mine is sourced from separate Russian suppliers. The diesel fuel price assumes a price of oil of approximately $53 per barrel. Crude oil is a component of diesel fuel purchased by the Company, such that changes in the price of Brent crude oil generally impacts diesel fuel prices.

Mount Milligan Streaming Arrangement
The Mount Milligan mine is an open pit mine located in north central British Columbia, Canada producing a gold and copper concentrate. Production at the Mount Milligan mine is subject to an arrangement with RGLD Gold AG and Royal Gold, Inc. (together, "Royal Gold") pursuant to which Royal Gold is entitled to purchase 35% of the gold produced and 18.75% of the copper production at the Mount Milligan mine for $435 per ounce of gold delivered and 15% of the spot price per metric tonne of copper delivered (the "Mount Milligan Streaming Arrangement"). To satisfy its obligations under the Mount Milligan Streaming Arrangement the Company purchases refined gold and copper warrants and arranges for delivery to Royal Gold. The difference between the cost of the purchases of refined gold and copper warrants, and the corresponding amounts payable to the Company under the Mount Milligan Streaming Arrangement is recorded as a reduction of revenue and not a cost of operating the mine.

Financial Performance

First Quarter 2021 compared to First Quarter 2020

Revenue of $401.9 million was recognized in the first quarter of 2021 compared to $378.8 million in the first quarter of 2020. The increase in revenue was due to 27,584 gold ounces sold at the ?ks?t mine, which commenced commercial production on May 31, 2020, higher average realized gold and copper prices and increased gold ounces sold at the Mount Milligan mine, partially offset by fewer gold ounces sold at the Kumtor mine.

Total gold production was 160,346 ounces in the first quarter of 2021 compared to 190,474 ounces in the first quarter of 2020. Gold production in the first quarter of 2021 included 90,169 ounces at the Kumtor mine, 41% less ounces than the comparable prior year period, due to the anticipated lower grades and recoveries. The Mount Milligan mine produced 42,576 ounces of gold in the first quarter of 2021, 26% more ounces than the first quarter of 2020, due to higher gold grades and recoveries. The ?ks?t mine, which was not in commercial production in the first quarter of 2020, produced 27,601 ounces of gold in the first quarter of 2021.

Copper production at the Mount Milligan mine was 18.6 million pounds in the first quarter of 2021 compared to 20.1 million pounds in the first quarter of 2020. The decrease in copper production was due to lower copper grades, which were partially offset by higher copper recoveries.

Gold production costs were $561 per ounce in the first quarter of 2021 compared to $437 per ounce in the first quarter of 2020. The increase was primarily due to lower ounces of gold sold at the Kumtor mine, compared to the same prior year period.

Copper production costs were $1.42 per pound in the first quarter of 2021 compared to $1.37 per pound in the first quarter of 2020. The increase in copper pounds sold in the first quarter of 2021, was offset by a higher allocation of production costs to copper as a result of the relative strength of the copper price compared to the gold price.

All-in sustaining costs on a by-product basis^NG were $745 per ounce in the first quarter of 2021 compared to $718 per ounce in the first quarter of 2020. The increase was due to lower ounces sold, increased sustaining capital at the Mount Milligan mine and greater capitalized stripping at the Kumtor mine, partially offset by increased copper credits due to a 69% increase in the average realized price of copper.

All-in costs on a by-product basis^NG were $1,073 per ounce in the first quarter of 2021 compared to $1,024 per ounce in the first quarter of 2020. The increase was due to higher all-in sustaining costs on a by-product basis^NG, explained above, and the planned purchase of haul trucks for the life of mine extension at the Kumtor mine, partially offset by lower revenue-based taxes paid by Kumtor.

The Langeloth Facility roasted 2.7 million pounds of molybdenum in the first quarter of 2021 compared to 4.4 million pounds in the first quarter of 2020. This decrease was the result of a decline in demand for industrial products that use molybdenum.

Exploration expenditures of $9.3 million were recognized in the first quarter of 2021 compared to $7.8 million in the first quarter of 2020. The increase in exploration expenditures was due to a significantly expanded drilling program at the Kumtor mine, drilling approximately 20,000 metres in the first quarter of 2021, as well as the recommencement of drilling activities at ?ks?t and Mount Milligan earlier in than the prior period.

Financing costs of $1.8 million were recognized in the first quarter of 2021 compared to $3.6 million in the first quarter of 2020. The decrease was due to the corporate revolving credit facility remaining undrawn during the first quarter of 2021.

Corporate administration costs of $4.9 million were recognized in the first quarter of 2021 compared to $3.4 million in the first quarter of 2020. The increase was primarily due to an increase in advisory and legal fees.

A gain on sale of $72.3 million (excluding contingent consideration) was recognized in the first quarter of 2021 on the disposal of the Company's 50% interest in the Greenstone Gold Mines Partnership.

Balance Sheet Review

Cash at March 31, 2021 was $823.2 million compared to $545.2 million at December 31, 2020. The increase was due to the receipt of $210 million as consideration for the disposal of the Company's 50% interest in the Greenstone Gold Mines Partnership and free cash flow^NG of $72.1 million generated in the first quarter of 2021.

Accounts receivable at March 31, 2021 was $106.4 million compared to $66.1 million at December 31, 2020. The increase is due to a shipment of gold from the Kumtor mine in late March 2021, for which the funds were collected in April 2021.

Total inventories at March 31, 2021 were $542.0 million compared to $580.6 million at December 31, 2020. Total inventory includes stockpiles of ore, gold in-circuit, gold dor?, copper and gold concentrate and molybdenum inventory (collectively "Product Inventory") of $323.6 million and supplies inventory of $218.4 million, compared to $373.1 million and $207.5 million, respectively, at December 31, 2020. The decrease in Product Inventory was primarily due to the Kumtor mine processing from stockpiles during a major stripping period in 2021.

At March 31, 2021, the Product Inventory balance consisted of 429,172 contained gold ounces on surface in stockpiles at Kumtor (9.9 million tonnes of ore with a grade of 1.337 g/t gold), of which roughly 51% is expected to be processed in 2021, 87,051 contained gold ounces and 20.3 million contained pounds of copper in surface stockpiles at Mount Milligan (6.5 million tonnes of ore at a grade of 0.42 g/t gold and 0.14% copper), of which roughly 15% is expected to be processed in 2021 and at the ?ks?t mine 3,083 contained gold ounces in solution at the absorption, desorption and recovery (ADR) plant and 644 contained gold ounces on surface and stacked (0.1 million tonnes of ore at a grade of 0.13 g/t gold in surface stockpiles and 1.32 g/t gold stacked on the heap leach pad), which is expected to be processed in 2021.

The book value of property, plant and equipment at March 31, 2021 was $1.72 billion compared to $1.69 billion at December 31, 2020. The increase was due to higher capitalized stripping and the purchase of haul trucks at the Kumtor mine.

The provision for reclamation at March 31, 2021 was $338.8 million compared to $352.2 million at December 31, 2020. An increase in the risk-free interest rate used to calculate the present value of reclamation costs at the Company's North American sites was the primary reason for the reduction in the obligation.

In 1998, a reclamation trust fund was established to cover the future costs of reclamation at the Kumtor mine. At March 31, 2021, this fund had a balance of $53 million and is shown as long-term asset on the balance sheet.

The Company's total liquidity position is $1,223.2 million, representing a cash balance of $823.2 million and $400 million available under the Corporate Credit Facility. The strong liquidity position and forecasted robust free cash flows from the Company's Kumtor, Mount Milligan and ?ks?t operations are expected to be sufficient to satisfy working capital needs, fund the Company's activities and meet other liquidity requirements through the end of 2021. See "Caution Regarding Forward-Looking Information".

Market Conditions

Commodity prices
The Company's profitability is materially affected by the market price of metals. Metal prices fluctuate widely and are affected by numerous factors beyond the Company's control.

Foreign Exchange
The Company has operations in Canada, including its corporate head office, the Kyrgyz Republic, Turkey and the United States. The Company receives its revenue through the sale of gold, copper and molybdenum in U.S. dollars.

A significant cost driver of Centerra is the performance of key currencies relative to the U.S. dollar. The performance of these currencies over a 24-month period and at key reporting dates was as follows:

Operating Mines and Facilities

Kumtor Mine
The Kumtor open pit mine, located in the Kyrgyz Republic, is one of the largest gold mines in Central Asia. It has been in production since 1997 and has produced over 13.3 million ounces of gold to March 31, 2021.

Kumtor Operating Results

First Quarter 2021 compared to First Quarter 2020
Earnings from mine operations of $88.8 million were recognized in the first quarter of 2021 compared to earnings from mine operations of $137 million in the first quarter of 2020. The decrease was primarily due to 39% fewer gold ounces sold, primarily due to lower average process plant head grades and lower gold recoveries as the Kumtor mine continues to process ore from on-surface stockpiles, partially offset by 13% higher average realized gold prices, lower production, depreciation and revenue-based tax costs.

A chart accompanying this announcement is available at https://www.globenewswire.com/NewsRoom/AttachmentNg/b59d1c93-963e-4ef0-b281-be9b1bdd7619

Cash provided by mine operations of $66.7 million was recognized in the first quarter of 2021 compared to $134.3 million in the first quarter of 2020. The decrease was primarily due to the lower earnings from mine operations mainly due to lower production, and lower cash from working capital as a result of inventory movements. In the first quarter of 2021, 55% more ore tonnes were mined which resulted in higher mining costs charged to stockpile inventory as compared to the comparative quarter.

Free cash flow from mine operations^NG of $4 million was recognized in the first quarter of 2021 compared to $95.6 million in the first quarter of 2020. The decrease was due to lower cash provided by mine operations and an increase in capital expenditure related to the purchase of additional haul trucks required for the life of mine extension. In the first quarter of 2021, Kumtor received seven of the eight haul trucks that it planned to purchase in 2021.

During the first quarter of 2021, the Kumtor mine continued mining in cut-back 20. Tonnes mined were 49.2 million in the first quarter of 2021 compared to 20 million tonnes in the first quarter of 2020. The increase was due to the suspension of mining operations in January 2020 due to the Lysii waste rock dump incident. Of the 49.2 million tonnes mined in the first quarter of 2021, 30.3 million were capitalized as waste stripping for the benefit of future gold production from cut-back 20.

Mining costs were $1.00 per tonne in the first quarter of 2021 compared to $1.77 per tonne in the first quarter of 2020. The decrease was primarily due to more tonnes mined and shorter haulage distances in 2021, partially offset by higher maintenance costs. Total mining costs were $49.1 million of which $30.5 million was capitalized in the first quarter of 2021, compared to $35.4 million in mining costs of which $30 million was capitalized in the first quarter of 2020.

Gold production was 90,169 ounces from on-surface stockpiled ore in the first quarter of 2021 compared to 152,307 ounces of gold produced in the first quarter of 2020. The decrease was primarily due to lower average process plant head grades and lower gold recoveries. During the first quarter of 2021, the Kumtor mine was processing ore with an average grade of 2.41 g/t and a recovery of 71.3% compared to ore from cut-back 19 with a higher average grade of 3.53 g/t and a recovery of 83.7% in the first quarter of 2020.

Processing costs were $10.17 per tonne in the first quarter of 2021 compared to $10.89 per tonne in the first quarter of 2020. The decrease was primarily due to lower costs associated with foreign contractors and carbon fine processing.

Gold production costs were $492 per ounce in the first quarter of 2021, compared to $334 per ounce in the first quarter of 2020. The increase was primarily due to lower ounces of gold sold.

A chart accompanying this announcement is available at https://www.globenewswire.com/NewsRoom/AttachmentNg/a851c419-adb6-41b6-8056-b72c1fb81497

All-in sustaining costs on a by-product basis^NG, which excludes revenue-based tax, were $888 per ounce in the first quarter of 2021 compared to $648 per ounce in the first quarter of 2020. The increase was primarily due to fewer ounces of gold sold.

All-in costs on a by-product basis^NG were $1,417 per ounce in the first quarter of 2021 compared to $902 per ounce in the first quarter of 2020. The increase was due to an increase in all-in sustaining costs on a by-product basis^NG and the planned purchase of additional haul trucks as required for the life of mine extension.

Mount Milligan Mine
The Mount Milligan Mine is an open pit mine located in north central British Columbia, Canada producing a gold and copper concentrate. Production at the Mount Milligan mine is subject to an arrangement with RGLD Gold AG and Royal Gold, Inc. (together, "Royal Gold") pursuant to which Royal Gold is entitled to purchase 35% of the gold produced and 18.75% of the copper production at the Mount Milligan mine for $435 per ounce of gold delivered and 15% of the spot price per metric tonne of copper delivered. To satisfy its obligations under the Mount Milligan Streaming Arrangement the Company purchases refined gold and copper warrants and arranges for delivery to Royal Gold. The difference between the cost of the purchases of refined gold and copper warrants, and the corresponding amounts payable to the Company under the Mount Milligan Streaming Arrangement is recorded as a reduction of revenue and not a cost of operating the mine.

Water Update
Stored water inventory at the Mount Milligan mine is critical to the ability to process ore through the mill process plant on a sustainable basis. Stored water was in excess of 4.5 million cubic metres as at March 31, 2021. In addition to accessing water from surface water sources throughout the first quarter of 2021, the Mount Milligan mine continued to access ground water from the Lower Rainbow Valley wellfield as well as other groundwater wells near the tailings storage facility during the quarter. The Company expects the water inventory level to increase through the summer of 2021 following the spring melt.

Exploration activities continue to focus on extending the groundwater capacity in the vicinity of the existing infrastructure. The Company continues to pursue a longer-term solution to its water requirements at the Mount Milligan mine and is in discussions with regulators, First Nations partners and other stakeholders. In April 2021, the Company's obtained an environmental assessment certificate amendment to access surface water sources for the Mount Milligan mine through November 2023, subject to the receipt of permits which are expected to be received shortly. The Company does not expect any interruptions to the Mount Milligan mine operations in the medium term when considering currently available water sources and inventory. See "Caution Regarding Forward-Looking Information".

Mount Milligan Operating Results

First Quarter 2021 compared to First Quarter 2020
Earnings from mine operations of $43.5 million were recognized in the first quarter of 2021 compared to $3.3 million in the first quarter of 2020. The increase was primarily due to higher average realized gold and copper prices, and an increase in ounces of gold and pounds of copper sold, partially offset by an increase in production costs and depreciation.

A chart accompanying this announcement is available at https://www.globenewswire.com/NewsRoom/AttachmentNg/1c1b674b-585e-413c-a7dd-3449c36500b8

Cash provided by mine operations of $89.7 million was recognized in the first quarter of 2021 compared to $27.2 million in the first quarter of 2020. The increase was primarily due to higher net earnings from mine operations (explained above) and an increase in cash generated from working capital. Working capital levels decreased by approximately $19 million in the first quarter of 2021, as a result of lower product inventories and higher payables due to the timing of shipments and of payments, partially offset by an increase in receivables. The reduction in working capital in the first quarter of 2020 was approximately $8 million.

Free cash flow from mine operations^NG of $80.2 million was recognized in the first quarter of 2021 compared to $22 million in the first quarter of 2020, due to an increase in cash provided by mine operations, partially offset by an increase in capital expenditures related to major planned equipment rebuilds and tailings storage facility development.

During the first quarter of 2021, mining activities were carried out in phases 4, 5 and 8 of the open pit. Total tonnes mined were 10.7 million tonnes in the first quarter of 2021 compared to 10.9 million tonnes in the first quarter of 2020.

Mining costs were $1.89 per tonne in the first quarter of 2021 compared to $1.75 per tonne in the first quarter of 2020. The increase was due to higher maintenance costs associated with planned repairs, higher tire costs as a result of higher tire consumption and lower tonnage mined.

Total mill throughput for the first quarter of 2021 was 4.8 million tonnes, averaging 53,000 tonnes per calendar day, compared to 4.9 million tonnes, averaging 53,500 tonnes per calendar day in the first quarter of 2020. Lower mill throughput was a result of a planned mill shutdown during the first quarter of 2021.

Gold production was 42,576 ounces in the first quarter of 2021 compared to 33,681 ounces in the first quarter of 2020. The increase was due to higher gold grades and recoveries, partially offset by lower throughput. During the first quarter of 2021, the average gold grade was 0.43 g/t with a recovery of 66% compared to 0.37 g/t with a recovery of 60% in the first quarter of 2020. Total copper production was 18.6 million pounds in the first quarter of 2021 compared to 20.1 million pounds in the first quarter of 2020. The decrease was due to lower copper grades and lower mill throughput, partially offset by higher copper recoveries.

Processing costs were $5.93 per tonne in the first quarter of 2021 compared to $4.93 per tonne in the first quarter of 2020. The increase was due to higher maintenance cost associated with the mill shutdown and lower tonnage processed. This was partially offset by lower electricity consumption.

Gold production costs were $675 per ounce in the first quarter of 2021 compared to $848 per ounce in first quarter of 2020. The decrease was due to more ounces of gold sold, partially offset by higher processing costs as a result of the planned mill shutdown and slightly higher mining costs.

Copper production costs were $1.42 per pound in the first quarter of 2021 compared to $1.37 per pound in the first quarter of 2020. The increase in copper pounds sold in the first quarter of 2021, was offset by a higher allocation of production costs to copper as a result of the relative strength of the copper price to the gold price.

A chart accompanying this announcement is available at https://www.globenewswire.com/NewsRoom/AttachmentNg/69d6bbc9-686a-4a0d-9dc3-51530cae8a4a

All-in sustaining costs on a by-product basis^NG were $367 per ounce in the first quarter of 2021 compared to $911 per ounce in the first quarter of 2020. The decrease was primarily due to 69% higher average realized copper prices and increased pounds of copper and ounces of gold sold, compared to the same prior year period, partially offset by higher production costs and sustaining capital.

All-in costs on a by-product basis^NG were $386 per ounce in the first quarter of 2021 compared to $923 per ounce in the first quarter of 2020. The decrease was due to lower all-in sustaining costs on a by-product basis^NG.

?ks?t Mine
The ?ks?t mine is located in Turkey approximately 300 kilometres southeast of Ankara and 48 kilometres south of Kayseri, the provincial capital. The nearest administrative centre is Develi, located approximately 10 kilometres north of the mine site.

Mining permit update
During 2020, the ?ks?t mine obtained an amendment to its environmental impact assessment ("EIA") to accommodate changes to the G?neytepe open pit's mine design and pit optimization although an application for the related forestry permit remains under review. The Company's expectation is that the high-grade ore of the G?neytepe deposit will be accessed in 2022, which remains unchanged.

?ks?t Operating Results
The ?ks?t mine achieved first gold pour on January 31, 2020 and achieved commercial production on May 31, 2020. Up to the point of achieving commercial production, gold revenue and the associated costs of production were capitalized.

First Quarter 2021
During the first quarter of 2021, earnings from mine operations were $24.1 million, cash provided by mine operations was $32 million and free cash flow from mine operations^NG was $25.7 million. Total gold ounces sold were 27,584, resulting in revenue of $49.9 million for the first quarter of 2021.

Non-sustaining capital expenditures in the first quarter of 2021 were $0.3 million compared to $8.8 million in the first quarter of 2020. The higher capital costs in the first quarter of 2020 were related to the final stages of the construction of the mine.

Mining in the first quarter of 2021 was focused on the development of phase 3 and phase 4 of the Keltepe pit, with total tonnes mined of 3.3 million. Processing in the first quarter of 2021 was focused on the preparation, stacking and irrigation of the heap leach pad, with tonnes stacked of 0.53 million at a gold grade of 0.83 g/t.

Gold production costs were $583 per ounce, all-in sustaining costs on a by-product basis^NG were $804 per ounce and all-in costs on a by-product basis^NG were $827 per ounce in the first quarter of 2021.

Molybdenum Business Unit
The molybdenum business includes two North American molybdenum mines that are currently on care and maintenance: the Thompson Creek mine in Idaho and the 75%-owned Endako mine in British Columbia. The molybdenum business also includes the Langeloth metallurgical roasting facility (the "Langeloth Facility") in Pennsylvania. The Thompson Creek mine (the "TC mine") operates a molybdenum beneficiation circuit to treat molybdenum concentrates to supplement the concentrate feed sourced directly for the Langeloth Facility. This beneficiation process allows the Company to upgrade high copper content molybdenum concentrate purchased from third parties into upgraded products which are then sold in the metallurgical and chemical markets.

Additionally, the molybdenum business provides tolling treatment services for customers by converting molybdenum concentrates to molybdenum oxide powder, briquettes and ferromolybdenum products.

First Quarter 2021 compared to First Quarter 2020
Net earnings from operations of $9.8 million was recognized in the first quarter of 2021 compared to a net loss of $41.2 million in the first quarter of 2020. The increase in the first quarter of 2021 was mainly due to the gain recorded resulting from the reduction in the underlying reclamation liability, as a result of a change in interest rates and a higher gross margin on materials sold.

Cash used in operations of $6.8 million was recognized in the first quarter of 2021, compared to cash provided by operations of $10.4 million in the first quarter of 2020. The decrease was due to a $11.4 million tax refund that was received in the first quarter of 2020. A free cash flow deficit from operations^NG of $7.5 million was recognized in the first quarter of 2021 compared to a free cash flow from operations^NG of $9.2 million in the first quarter of 2020, due to the tax refund received in 2020.

The Langeloth Facility roasted and sold 2.7 million pounds and 3.3 million pounds of molybdenum, respectively, in the first quarter of 2021, compared to 4.4 million pounds and 3.8 million pounds of molybdenum in the first quarter of 2020. This decrease in volume was the result of a decline in demand for industrial products that use molybdenum in 2021.

Pre-Development Projects

Kemess Underground Project:
The Kemess Project ("Kemess") is located in north-central British Columbia, Canada, approximately 250 kilometres north of Smithers, 430 kilometres northwest of Prince George and 209 kilometres from the Mount Milligan mine. The Kemess site includes infrastructure from the past producing Kemess South mine. There are currently no mining activities at the Kemess site and on-site activities consist of care and maintenance work and pre-development activities for the proposed Kemess Underground Project.

First Quarter 2021 compared to First Quarter 2020
Care and maintenance costs of $3.2 million were recognized in the first quarter of 2021, compared to $3.5 million recognized in the first quarter of 2020. Capital expenditures of $0.2 million were recognized in the first quarter of 2021, compared to $1.8 million in the first quarter of 2020. The capital expenditures in the first quarter of 2021 included costs for completion of the value engineering project scope initiated in 2020. The capital expenditures in the first quarter of 2020 included costs for technical engineering studies, water treatment plant performance testing preparation and southern collection system pond construction. The water treatment plant was completed and commissioned in September 2020.

Greenstone Gold Property:
The Greenstone Gold property is located in northern Ontario, Canada approximately 275 kilometres northeast of Thunder Bay and includes the Hardrock deposit.

On December 15, 2020, the Company entered into an agreement with an affiliate of the Orion Mine Finance Group ("Orion") and Premier Gold Mines Ltd. to sell the Company's 50% interest in the Greenstone Gold Mines Partnership to Orion for cash consideration of $225 million, subject to certain adjustments, and contingent consideration of approximately $75 million, assuming a gold price of $1,500 per ounce, based on the successful construction and operation of the mine, which will be recorded on achieving the applicable milestones.

On January 19, 2021, the Company completed the sale of its 50% interest in the Greenstone Gold Mines Partnership with final cash consideration received of $210 million, net of adjustments, and recognized a gain on sale of $72.3 million (excluding contingent consideration).

Quarterly Results - Previous Eight Quarters

Over the last eight quarters, Centerra's results reflect the impact of consistent gold and copper sales during a period of rising prices. Production costs have benefited from the depreciating Kyrgyz and Turkish currencies over the last eight quarters. Gold sold on a quarterly basis steadily increased from the second quarter of 2019 to the third quarter of 2019, followed by a slight decline in the fourth quarter of 2019, increasing again in the first nine months of 2020 as the ?ks?t mine reached commercial production on May 31, 2020, declining in the fourth quarter of 2020 due to lower ounces of gold sold at Kumtor and rising again in the first quarter of 2021. The loss in the third quarter of 2019 reflects the impairment of $230.5 million recorded on the Mount Milligan mine and a $10 million Kyrgyz Republic settlement expense. As a result of a change in the interest rate used to discount the reclamation costs at the two molybdenum mine sites which are not in operation, a non-cash reclamation expense was recognized in the fourth quarters of 2019 and 2020 of $31.4 million and $53.4 million, respectively, while a recovery of $10.9 million was recognized in the first quarter of 2021. The first quarter of 2021 also reflects a gain of $72.3 million on the sale of the Greenstone property. The quarterly financial results for the last eight quarters are shown below:

Related party transactions

Kyrgyzaltyn
The sole customer of gold dor? from the Kumtor mine, Kyrgyzaltyn JSC ("Kyrgyzaltyn"), is a shareholder of the Company and is a state-owned entity of the Kyrgyz Republic. Revenues from the Kumtor mine are subject to a management fee of $1.00 per ounce based on sales volumes, payable to Kyrgyzaltyn. In addition, Kyrgyzaltyn is obligated to provide contracting services in support of Kumtor's mining activities.

During the first quarter of 2021, net revenue received for gold and silver sales by Kumtor to Kyrgyzaltyn amounted to $175.6 million ($250.8 million in the first quarter of 2020). Contracting services and management fees payable to Kyrgyzaltyn totalled $0.4 million in the first quarter of 2021 ($0.3 million in the comparative quarter of 2020).

Contingencies

The following is a summary of contingencies with respect to matters affecting the Company and its subsidiaries. Readers are cautioned that the following is only a brief summary of such matters. For a more complete discussion of these matters, see the Company's news releases and its most recently filed Annual Information Form and specifically the section therein entitled "Risks that can affect our business" available on SEDAR at www.sedar.com.The following summary also contains forward-looking statements and readers are referred to "Caution Regarding Forward-looking Information".

Kyrgyz Republic

State Commission
In February 2021, a Kyrgyz Republic State Commission (the "State Commission") was formed to review the effectiveness of the Kumtor Mine's performance and to oversee the implementation of the recommendations of a previous Kyrgyz Parliamentary resolution which established a State Commission in July 2012. The Company and its wholly owned subsidiary, KGC, have received a significant number of detailed inquiries from the State Commission, as well as related inquiries from other state agencies and bodies, including Kyrgyzaltyn, and is continuing to respond to all such inquiries. The Company understands that the State Commission has completed its review and will issue a report shortly.

New and Proposed Legislation

External Management Legislation
As previously disclosed, the Company understands that a new law has been passed by the Kyrgyz Republic Parliament which would enable the Kyrgyz Republic Government to impose "external management" on companies in the Kyrgyz Republic operating under concession agreements. The sponsor of the law, Mr. Akylbek Japarov, publicly noted that the only project operating under a concession agreement in the Kyrgyz Republic is the Kumtor Mine.

Accordingly, the Company understands that this newly adopted law on external management would apply in circumstances where KGC violates certain Kyrgyz laws relating to safety and thereby creates an immediate threat to the life or health of people. In such circumstances, the law would (i) enable the Prime Minister of the Kyrgyz Republic to appoint an external manager to take control of all management activities of KGC, including its bank accounts, and (ii) prohibit the Company or KGC's board of directors from directing the external managers (or else face criminal sanctions). Mr. A. Japarov, who proposed this new law, is also the Chairman of the Kyrgyz Republic State Commission referred to above.

Draft Legislation Undermining 2009 Restated Project Agreements
The Company also understands that two draft laws relating to Kumtor have been posted for public discussion on the Kyrgyz Republic Parliament's website. Such draft laws appear to amend the 2009 Kyrgyz Republic Law which ratified the Agreement of New Terms for the Kumtor Project, the 2009 Restated Project Agreements and special fiscal and tax regime established therein for the Kumtor Project. The precise impact of the draft laws is unclear since there remain gaps in the drafting of the proposal; however, the drafts have the potential to fundamentally alter the legal foundation under which the Kumtor Mine has operated since 2009. Furthermore, the Company is aware of a draft decree of the Kyrgyz Republic Government which appears to be seek ownership over the Kumtor's Mine's tailings facilities.

Citizens Claims for Waste Rock Dumping on Glaciers
In March 2021, four Kyrgyz Republic private citizens commenced a civil claim against KGC seeking a determination that KGC's past practice of placing waste rock on glaciers was illegal. In early May 2021, the Claimants amended their claim to demand over $3 billion in environmental damages to be paid to the Kyrgyz Republic. The Company notes that one of the claimants is the son of the current Director of the Kyrgyz Republic State Agency for Environment Protection and Forestry ("SAEPF"). The hearing on the merits of this citizen claim was commenced in early May 2021 and a decision was rendered by the Kyrgyz court on May 7, 2021, with a demand that KGC pay approximately $3.1 billion to the Kyrgyz Republic state. KGC is reviewing the court decision and plans to appeal this decision, while reserving its right to international arbitration. The Company notes that the Strategic Agreement resolved all outstanding environmental disputes between the Kyrgyz Republic Government and KGC relating to the Kumtor Project, including "damages for harm allegedly caused to the environment by storing production tails on glaciers".

Tax Claims
On March 18, 2021, Centerra disclosed certain tax claims received by its Kyrgyz Republic subsidiary KGC, from the Kyrgyz Republic State Tax Service ("STS") for an aggregate of approximately $146 million (subsequently increased to approximately $352 million) and which cover a variety of tax years, as more fully described below. In some cases, these claims contradict previous decisions from the STS and the Kyrgyz courts and include significant penalties and / or sanctions that in some cases are more than half of the total amount claimed. The Company believes the claims are exaggerated and without merit and is challenging the claims in the Kyrgyz courts while reserving its rights to international arbitration.

The claims commenced by STS against KGC cover a variety of bases and years, including tax years which STS re-audited. In some cases, there are no monetary amounts attributed yet to the claim, but management estimates that the aggregate amount that could be claimed by STS on the bases set out below and the years being audited/re-audited is approximately $352 million (which includes amounts disclosed in the March 18, 2021 news release). Unless otherwise stated below, these claims have been brought by the STS and are not yet subject to any court proceedings. Where court proceedings are occurring, KGC has reserved its rights to international arbitration. The bases for the tax claims include the following:

1. Dividend Claims: Claims covering a variety of years related to withholding taxes on dividends paid by KGC to its direct parent company, Centerra. Management estimates that these claims are for an aggregate of approximately $147 million which includes approximately $55 million for penalties and sanctions. KGC has challenged the decision of the STS in relation to their request for withholding taxes for the tax year 2016-2017 before the Kyrgyz administrative courts;
   
   
2. Social Fund Claims: Claims covering a variety of years in relation to alleged underpayments to the Kyrgyz Republic Social Fund. Management estimates that the aggregate amounts under these claims could be $21 million, which includes approximately $10 million in penalties. KGC received a statement of claim in relation to amounts allegedly owing for the years 2016-2017 and is disputing the claim;
   
   
3. Employee Income Tax Claims: Claims covering a variety of years related to payroll deductions not withheld by KGC on certain premiums paid primarily to national employees. Management estimates that the aggregate amounts are of these claims are approximately $36 million, which includes approximately $9.5 million in penalties. STS has applied to a Kyrgyz appeal court in respect to the years 2016 and 2017, and to specifically overturn a lower court's 2018 decision in favour of KGC which ruled that certain premiums payable to Kumtor employees were not subject to income tax withholdings. In a single hearing, the Kyrgyz appeal court reinstated the appeal period, quashed the lower court ruling in favour of KGC, and ruled on the merits against KGC on all issues. While KGC has appealed the decision to the Supreme Court, it is possible that the State Tax Service may demand payment in respect of these amounts which the Company expects to be approximately $17 million (included in the $36 million noted above); and
   
   
4. Annual Amounts under the Restated Investment Agreement: The Kyrgyz Republic is also claiming that KGC has not fulfilled its obligations under the Restated Investment Agreement regarding paying an annual amount equal to 4% of Kumtor's gross proceeds, beginning from 2010. The Company disputes this claim and has referred the regulatory authorities to the full provision in the 2009 Restated Investment Agreement which sets out the calculation and the credits which are available to KGC in determining whether any annual amount is payable. Management estimates that the aggregate amount of this claim is approximately $148 million.

Centerra notes that the 2009 Restated Project Agreements which govern the Kumtor Mine contain a specific tax and fiscal regime applicable to the Kumtor Mine. That tax and fiscal regime provides, among other things, that no taxes are payable by KGC on intercompany transactions with Centerra, including dividends. The 2009 Restated Project Agreements were confirmed by the Kyrgyz Republic Government in the Kumtor Strategic Agreement signed on September 11, 2017, which was completed and reaffirmed in August 2019.

New Barskoon Claimants
In January 2021, the Kyrgyz Republic Supreme Court upheld a lower court ruling awarding damages and other costs to plaintiffs in the 1998 Barskoon truck accident case. An aggregate total of KGS 7,200,000 (or approximately $91,000) was awarded in damages. That decision is final and not subject to further appeal. KGC paid all plaintiffs the required amounts and the process was completed in early March 2021. Under a 1999 settlement agreement, the Kyrgyz Republic Government has agreed to indemnify KGC from any damages in connection with the Barskoon cyanide incident and, under the terms of the 2009 Restated Project Agreements, KGC may set off such amounts against future taxes payable to the Government.

On April 12, 2021, KGC received a new Statement of Claim initiated by 54 residents of Barskoon, Tosor, Kichi Zhargylchak and Chon Zhargylchak villages of Jety-Oguz District, seeking compensation in the amount of KGS 2 million (or approximately $24,000) for each plaintiff in relation to the Barskoon accident. KGC understands that the Kyrgyz court has returned the Statement of Claim and refused to accept the claim for further consideration.

New and Re-Opened Criminal Proceedings
The Company understands that the Kyrgyz Republic authorities have opened an investigation into KGC allegedly exporting antimony ores or concentrates from the Kyrgyz Republic, which the KGC denies. The Company also understands that such authorities have re-opened previously closed criminal investigations including those related to the Lysii waste dump incident in 2019 and the Petrov Lake incident in 2020. In this regard, KGC notes that the Kyrgyz commissions previously formed to review such incidents concluded that no crime had occurred in each case.

The Company believes that the actions of the Kyrgyz Republic authorities described above are a concerted effort to coerce Centerra to give up economic value or ownership of the Kumtor Mine or to falsely justify a nationalization of the Kumtor Mine. While the Company has benefited from a close and constructive dialogue with the Kyrgyz Republic authorities over many years and remains committed to trying to work with them to resolve any outstanding issues in accordance with the 2009 Restated Project Agreements applicable to the Kumtor Mine, it will not hesitate to use all legal avenues to protect its legal rights and interests and those of its shareholders and will pursue its claims in international arbitration proceedings.

In light of the above developments, the Company has formally notified the Kyrgyz Republic Government that, among other things, their actions or threatened actions, including new and proposed legislation, and the actions by the STS, violate or may violate terms of the 2009 Restated Investment Agreement and related project agreements applicable to the Kumtor Mine, and constitute "Disputes" under those agreements.

There can be no assurance that any of these matters can be resolved without a material impact on the Company. There remains the further risk that additional regulatory, tax, or civil claims will be commenced against the Company, and that additional legislation is introduced which may impact the Kumtor Mine's operations. See "Caution Regarding Forward-Looking Information" and the section titled "Risks Factors" in our most recently completed Annual Information Form.

Canada

Mount Milligan Mine

As previously disclosed, in the first quarter of 2020, the Company received a notice of civil claim from H.R.S. Resources Corp. ("H.R.S."), the holder of a 2% production royalty at Mount Milligan. H.R.S. claims that since November 2016 (when the royalty became payable) the Company has incorrectly calculated amounts payable under the production royalty agreement and has therefore underpaid amounts owing to H.R.S. The Company disputes the claim and believes it has correctly calculated the royalty payments in accordance with the agreement. The Company believes that the potential exposure in relation to this claim, over what the Company has accrued, is not material.

Other

The Company operates in multiple countries around the world and accordingly is subject to, and pays taxes under the various regimes in those jurisdictions in which it operates. These tax regimes are determined under general taxation and other laws of the respective jurisdiction. The Company has historically filed, and continues to file, all required tax returns and to pay the taxes reasonably determined to be due. The tax rules and regulations in many countries are complex and subject to interpretation. From time to time the Company's tax filings are subject to review and in connection with such reviews, disputes can arise with the taxing authorities over the Company's interpretation of the country's tax laws. The Company records provisions for future tax assessments considered to be probable. As at March 31, 2021, the Company did not have any material provision for claims or taxation assessments.

Accounting Estimates, Policies and Changes

Accounting Estimates
The preparation of the Company's consolidated financial statements in accordance with IFRS required management to make estimates and judgments that affect the amounts reported in the consolidated financial statements and accompanying notes. The critical estimates and judgments applied in the preparation of the Company's condensed consolidated interim financial statements for the three months ended March 31, 2021 are consistent with those used in the Company's consolidated financial statements for the year ended December 31, 2020.

Management's estimates and underlying assumptions are reviewed on an ongoing basis. Any changes or revisions to estimates and underlying assumptions are recognized in the period in which the estimates are revised and in any future periods affected. Changes to these critical accounting estimates could have a material impact on the consolidated financial statements.

The key sources of estimation uncertainty and judgment used in the preparation of the consolidated financial statements that have a significant risk of causing a material adjustment to the carrying amounts of assets and liabilities and earnings within the next financial year are outlined in detail in note 4 of the December 31, 2020 financial statements.

Disclosure Controls and Procedures and Internal Control Over Financial Reporting

The Company's management, including the CEO and CFO, is responsible for the design of disclosure controls and procedures ("DC&P") and internal controls over financial reporting ("ICFR"). Centerra adheres to the Committee of Sponsoring Organizations of the Treadway Commission's ("COSO") revised 2013 Internal Control Framework for the design of its ICFR. There was no material change to the Company's internal controls over financial reporting that occurred during the first quarter of 2021 that has materially affected, or is reasonably likely to materially affect, the Company's internal controls over financial reporting.

The evaluation of DC&P and ICFR was carried out under the supervision of and with the participation of management, including Centerra's CEO and CFO. Based on these evaluations, the CEO and the CFO concluded that the design of these DC&P and ICFR were effective throughout the first quarter of 2021.

Non-GAAP Measures

This document contains the following non-GAAP financial measures: all-in sustaining costs per ounce on a by-product basis, all-in sustaining costs per ounce on a by-product basis including revenue-based taxes, all-in sustaining costs per ounce on a co-product basis and all-in costs on a by-product basis per ounce. In addition, non-GAAP financial measures include adjusted net earnings, adjusted net earnings per common share (basic and diluted), average realized gold price, average realized copper price, adjusted cash provided by operations, free cash flow from operations and adjusted free cash flow from operations. These financial measures do not have any standardized meaning prescribed by GAAP and are therefore unlikely to be comparable to similar measures presented by other issuers, even as compared to other issuers who may be applying the World Gold Council ("WGC") guidelines, which can be found at http://www.gold.org.

Management believes that the use of these non-GAAP measures will assist analysts, investors and other stakeholders of the Company in understanding the costs associated with producing gold, understanding the economics of gold mining, assessing our operating performance, our ability to generate free cash flow from current operations and to generate free cash flow on an overall Company basis, and for planning and forecasting of future periods. However, the measures do have limitations as analytical tools as they may be influenced by the point in the life cycle of a specific mine and the level of additional exploration or expenditures a company has to make to fully develop its properties. Accordingly, these non-GAAP measures should not be considered in isolation, or as a substitute for, analysis of our results as reported under GAAP.

Definitions
The following is a description of the non-GAAP measures used in this MD&A:

• All-in sustaining costs on a by-product basis per ounce include adjusted operating costs, the cash component of capitalized stripping costs, corporate general and administrative expenses, accretion expenses, and sustaining capital, net of copper and silver credits. The measure incorporates costs related to sustaining production. When calculating all-in sustaining costs on a by-product basis, all revenue received from the sale of copper from the Mount Milligan mine, as reduced by the effect of the copper stream, is treated as a reduction of costs incurred. All-in sustaining costs on a by-product basis per ounce excludes revenue-based taxes.
  
• All-in sustaining costs on a co-product basis per ounce of gold or per pound of copper, are based on an allocation of production costs between copper and gold based on the conversion of copper production to ounces of gold equivalent. For the first quarter of 2021, 475 pounds of copper were equivalent to one ounce of gold. All-in sustaining costs on a co-product basis per ounce of gold or per pound of copper excludes revenue-based taxes.
• All-in costs on a by-product basis per ounce include all-in sustaining costs on a by-product basis including revenue-based taxes, exploration and study costs, non-sustaining capital expenditures, care and maintenance and pre-development costs.
• Non-sustaining capital expenditures are costs incurred at new operations and costs related to major projects at existing operations where these projects will materially benefit the operation.
• Adjusted net earnings is calculated by adjusting net earnings (loss) as recorded in the consolidated statements of income (loss) and comprehensive income (loss) for items not associated with ongoing operations.
• Adjusted cash provided by operations is calculated by adjusting cash provided by operations as recorded in the condensed consolidated interim statements of statements of cash flows for items not associated with ongoing operations.
• Average realized gold price is calculated by dividing the different components of gold sales (including third party sales, mark to market adjustments, final pricing adjustments and the fixed amount received under the Mount Milligan Streaming Arrangement⁽¹⁾) by the number of ounces sold.
• Average realized copper price is calculated by dividing the different components of copper sales (including third party sales, mark to market adjustments, final pricing adjustments and the fixed amount received under the Mount Milligan Streaming Arrangement⁽¹⁾) by the number of pounds sold.
• Free cash flow is calculated as cash provided by operations less additions to property, plant and equipment.
• Free cash flow from mine operations is calculated as cash provided by mine operations less additions to property, plant and equipment.
• Adjusted free cash flow from operations is calculated as free cash flow adjusted for items not associated with ongoing operations.

Certain unit costs, including all-in sustaining costs on a by-product basis (including and excluding revenue-based taxes) per ounce are non-GAAP measures and can be reconciled as follows:

Adjusted net earnings can be reconciled as follows:
Adjusted net earnings is intended to provide investors with information about the Company's continuing income generating capabilities. This measure adjusts for the earnings impact of items not associated with ongoing operations.

Free cash flow is calculated as follows:

Average realized sales price for gold
The average realized gold price per ounce is calculated by dividing gold sales revenue, together with the final pricing adjustments, impact of reduced metal prices resulting from the Mount Milligan Streaming Arrangement, the impact of gold hedges and mark-to-market adjustments by the ounces sold, as shown in the table below:

Average realized sales price for Copper - Mount Milligan
The average realized copper price per pound is calculated by dividing copper sales revenue, together with the final pricing adjustments, impact of reduced metal prices resulting from the Mount Milligan Streaming Arrangement, the impact of copper hedges and mark-to-market adjustments by the pounds sold, as shown in the table below:

Supplementary Information: First Quarter 2021 Exploration Update

Exploration activities in the first quarter of 2021 included drilling, surface sampling, geological mapping and geophysical surveying at the Company's various projects (including earn-in properties), targeting gold and copper mineralization in Canada, Turkey, Finland, USA and the Kyrgyz Republic. Exploration expenditures were $9.3 million in the first quarter of 2021 compared to $7.8 million in the same quarter of 2020. The increase in exploration expenditures was due to a significantly expanded drilling program at the Kumtor mine, drilling approximately 20,000 metres in the first quarter of 2021, as well as the recommencement of drilling activities at ?ks?t and Mount Milligan earlier in than the prior period.

Kumtor Mine

The planned drilling program for 2021 includes 75,000 metres of exploration drilling, which will be focused on priority and high potential targets. Primary targets include various zones in the Central, Southwestern and Sarytor pits where a recently updated Kumtor resource block model, based on enhanced geological modelling and positive drilling results between 2018 and 2020, demonstrated substantial growth in measured, indicated, and inferred resources. As well, inferred SW and NE extensions of the Kumtor Gold Trend, i.e., the Bordoo, Akbel and Petrov targets, will be drill tested.

During the first quarter of 2021, exploration drilling programs continued with the completion of 57 diamond drill holes for 17,515 metres, and 20 reverse circulation ("RC") drill holes for 2,426 metres. Exploration drilling focused on testing zones of sulphide and oxide gold mineralization, at the Koshuluu, Hope, Triangle and Deep Oxide Zones, and on testing the periphery of the Sarytor, Bordoo and Muzdusuu areas and Northeast targets.

Central Pit
In the Triangle Zone of the Central Pit, four exploration drill holes were completed in the first quarter of 2021 for a total of 666 metres. The drill holes cut several intervals with sulfide gold mineralization, in which gold grades were >1 gram per tonne (g/t).

Southwest Area
In the first quarter of 2021, a total of 24 diamond drill holes were completed in the Southwest area for a total of 8,000 metres. The majority of the drill holes have been completed in the Koshuluu, Deep Oxide and Hope Zones.

In the Koshuluu Zone, 15 drill holes were completed for a total of 5,278 metres, between section -110 and section -134 (260 metres), where broad intervals of sulfide gold mineralized rocks, which belong to Unit 2, were intersected. Selected significant intercepts from the Koshuluu Zone are reported below:

In the Deep Oxide Zone, six drill holes were completed for a total of 2,266 metres. Selected significant intervals from the Deep Oxide Zone are reported below:

In the Hope Zone, three drill holes were completed for a total of 456 metres. Results from recent drilling have confirmed a zone of lens-shaped oxide gold mineralization. This mineralization extends along the hanging wall of the Kumtor Lower Thrust for more than 400 metres. Maximum thickness of the oxide gold mineralization is around 20 metres. Selected significant intervals from Hope Zone are reported below:

Muzdusuu Area
Eight diamond drill holes were completed in the Muzdusuu Area for a total of 1,369 metres. Drilling in the Muzdusuu Area (outside Central Pit) is designed to explore for oxide and mixed gold mineralization along the Kumtor Lower Thrust. Gold mineralization has been traced in both the northeast and southwest directions, which demonstrates continuity and a substantial volume under the ultimate Central pit. Selected significant intercepts from Muzdusuu Area are reported below:

Sarytor Area
In the first quarter of 2021, a total of six diamond drill holes were completed in the Sarytor area for a total of 1,557 metres. Several drill holes have intersected significant sulfide gold mineralization, they are listed below:

Bordoo Area
In the first quarter of 2021, a total of nine diamond drill holes were completed in the Bordoo area for a total of 3,541 metres. A few drill holes had minor intersections with sulfide gold mineralization. Selected significant intercepts are reported below:

Airport Area
In the first quarter of 2021, twelve RC drill holes were completed in the Airport area for a total of 600 metres. No significant gold mineralization has been intersected at the time of this report.

The above mineralized intercepts were calculated using a cut-off grade of 1.0 g/t Au for sulfide and 0.1 g/t Au for oxide gold mineralization, minimum interval of 4.0 metres and a maximum internal dilution interval of 5.0 metres. The true widths for sulfide gold mineralized intervals reported represent approximately 70 to 95% of the stated down hole interval. Significant assay intervals reported for oxide gold mineralization represent apparent widths due to the uncertainty of the nature of the mineralization at the time of reporting. Drill collar locations and associated graphics are available at the following link: http://ml.globenewswire.com/Resource/Download/ebc019dc-6dc1-46a5-a948-2fde2391fd4f

A full listing of the drill results, drill hole locations and plan map (including the azimuth, dip of drill holes, and depth of the sample intervals) for the Kumtor Mine have been filed on the System for Electronic Document Analysis and Retrieval ("SEDAR") at www.sedar.com and are available at the Company's web site at www.centerragold.com.

Mount Milligan Mine

The 2021 exploration drilling program at Mount Milligan Mine includes 20,000 metres of planned brownfield drilling (~50 drill holes) and 4,200 metres of planned greenfield drilling (~nine drill holes). Primary targets include zones below the current ultimate pit boundary (MBX Deep) and on the eastern margin of the pit (Great Eastern Fault) where positive drilling results were returned in 2019 and 2020.

Mount Milligan Brownfield Drilling and Exploration
Exploration drilling resumed in the first quarter of 2021, with seven diamond drill holes completed totaling 2,395 metres. Of these, four drill holes (1,265 metres) were part of the Southern Star zone in-fill drilling program designed to increase confidence in models prior to mining. Three drill holes (1,130 metres) were completed in the MBX Deep zone, an exploration target in the central portion of the deposit, below the current ultimate pit boundary. The MBX Deep drilling is testing for a potential corridor of high grade (>0.7% Copper Equivalent) mineralization underlying the MBX composite stock.

During the first quarter of 2021, assay results were returned for 25 drill holes completed in 2020 and 2021. These include significant mineralization from the DWBX zone and Zone-4 in the northwestern margin of the pit, the King Richard zone in the western margin of the pit, and the Southern Star zone within and along the southwestern margin of the pit.

The first assays returned from the MBX Deep zone (drill hole 21-1301) show wide intercepts of significant mineralization below the 2020 ultimate pit boundary, and extend the zone intersected in drill hole 20-1269 to the south-southwest up to 65 metres.

Selected significant intersections are reported below:

DWBX Zone (northwestern margin of the pit)

MBX Deep Zone (central portion of the pit)

Zone-4 (northwestern margin of the pit)

King Richard (western margin of the pit)

Southern Star (southwestern margin of the pit)

Significant intersections at Mount Milligan are generally hosted in andesite or latite volcaniclastic rocks, narrow monzonite porphyry units or larger stocks (hangingwall and footwall margins), or hydrothermal breccia units, and can be proximal to fault structures and related breccia/fracture zones. Early-stage alteration is variably potassic (magnetite bearing) and inner-propylitic (albite bearing) with early-stage gold-copper mineralized veins. This assemblage is variably overprinted by quartz-sericite-pyrite-carbonate (QSPC) alteration with associated transitional- to late-stage pyrite rich veins. The overprinting QSPC assemblage can be grade enhancing, particularly for gold, and is the predominant assemblage in parts of the deposit.

The assays returned from the Southern Star and DWBX zones along the western pit walls show an extension of low-grade porphyry Au-Cu mineralization associated with monzonite porphyry and magmatic-hydrothermal breccias continuing to the west of the current pit wall and below the ultimate pit boundary. Intervals of high gold-low copper mineralization (Zone-4 and King Richard zones) have of up to 10% transitional pyrite ? chalcopyrite stringers, veins, and semi-massive late-stage pyrite-calcite veins.

The above mineralized intercepts were calculated using a cut-off grade of 0.1 g/t Au and a maximum internal dilution interval of 4 metres. Asterisk (*) indicates preliminary result for Cu. Significant assay intervals reported represent apparent widths due to the undefined geometry of mineralization in this zone, relationship between fault blocks, and conceptual nature of the exploration target. Drill collar locations and associated graphics are available at the following link: http://ml.globenewswire.com/Resource/Download/ebc019dc-6dc1-46a5-a948-2fde2391fd4f

A full listing of the drill results, drill hole locations and plan map (including the azimuth, dip of drill holes, and depth of the sample intervals) for the Mount Milligan Mine have been filed on the System for Electronic Document Analysis and Retrieval ("SEDAR") at www.sedar.com and are available at the Company's web site at www.centerragold.com.

?ks?t Mine

At the ?ks?t mine, all of the outstanding assay results from the fourteen drill holes completed at the end of the last quarter of 2020 were received. The assay results returned significant intercepts at the Keltepe, G?neytepe, and Keltepe North deposits. The intercepts warrant additional infill drill holes to convert inferred material into indicated/measured within both the Keltepe and G?neytepe resource pit shells and indicated the extension of Keltepe North mineralization further to the northeast.

The 2021 drilling program commenced in the first quarter with infill and geotechnical drilling programs at Keltepe. About 1,000 metres were drilled in five drill holes. The 2021 drilling program includes 26,000 planned metres focusing on:

• expanding the gold resources at Keltepe and G?neytepe main mineralized zones,
• developing the Keltepe N/NW oxide gold satellite resources,
• targeting geochemical gold and geophysical anomalism which has not been tested before, and
• deeper sulphide gold and supergene copper mineralization potential.

Also in the quarter, four samples were collected from G?neytepe and one from Keltepe sulphide gold zones and were dispatched to a third party for detailed metallurgical studies including mineralogy, diagnostic heap leach, and flotation testing. The metallurgical tests are expected to be completed in the third quarter of 2021.

The selected significant intercepts for the outstanding assays from the fourth quarter of 2020 and the recent assays from the first quarter of 2021 are reported below:

Keltepe (resource upgrade and expansion of oxide gold)
