For references denoted with NG, refer to the "Non-GAAP and Other Financial Measures" disclosure at the end of this news release for a description of these measures.

2022 Fourth Quarter and Annual Production Highlights

• Gold production in the fourth quarter of 2022 was 53,222 ounces solely from the Mount Milligan Mine.
• Full year 2022 gold production was 243,868 ounces, including 189,177 ounces of gold produced by the Mount Milligan Mine and 54,691 ounces produced by the Öksüt Mine. Additionally, approximately 100,000 recoverable ounces was processed into gold-in-carbon form in 2022 and remains stored at the Öksüt Mine.
• Copper production was 16.9 million pounds in the fourth quarter and 73.9 million pounds for the full year 2022.

2023 Mount Milligan Mine Guidance Highlights

• 2023 guidance at the Mount Milligan Mine is expected as follows:
  • Gold production of 160,000 to 170,000 ounces.
  • Copper production of 60 to 70 million pounds.
  • Gold production costs per ounce - $900 to $950.
  • All-in sustaining costs ("AISC") on a by-product basis per ounce^NG - $1,075 to $1,125.
  • All-in costs ("AIC") on a by-product basis per ounce^NG - $1,125 to $1,175.
  • Additions to PP&E - $65 to $70 million.
  • Total capital expenditures^NG - $65 to $70 million.

Update on Öksüt Mine Operations

Gold doré bar production remains suspended at the Öksüt Mine due to mercury detected in the gold room at the ADR plant in March 2022. The Company is currently completing construction of a mercury abatement system to allow processing of mercury bearing ores and is scheduled to be completed in late January. The total capital costs are on target at approximately $5 million. The Company is working with the relevant authorities for the required approvals to restart gold room operations at the ADR plant, which the Company expects will occur shortly after the new Environment Impact Assessment ("EIA") for the Öksüt Mine is approved.

The Company recently submitted its updated EIA. The Company is now working with Turkish officials on the regulatory review and approval of its EIA and such other permits that may be required to allow a timely full restart of all operations.

The Company is also engaged in other ordinary course permitting matters and in January 2023 it received notices of approval of its operating license extension application for a period of 10 years as well as approval of an enlarged grazing land permit to allow expansion of the Keltepe and Güneytepe pits as planned.

Paul Wright, Interim President and Chief Executive Officer of Centerra, said: "Record annual mill throughput highlighted the Mount Milligan Mine's operating performance in 2022. We anticipate steady production at Mount Milligan in 2023, with management continuing to focus on optimizing the life of mine plan for future years. Cost guidance for the Mount Milligan Mine in 2023 includes the inflationary impact on costs that were prevalent globally through 2022. I am also pleased to report that we have received a 10-year operating license extension for the Öksüt Mine, in addition to the approval of an enlarged grazing land permit. Construction of the mercury abatement system is substantially complete and we are working with the applicable Turkish officials on their review and approval of the updated EIA."

Mount Milligan Mine 2023 Guidance

The Mount Milligan Mine's 2023 copper production is expected to be back-end weighted with approximately 35% of concentrate sales expected to occur in the fourth quarter of 2023.

The 2023 cost guidance and capital expenditure metrics are higher when compared to the Mount Milligan Mine's December 31, 2021 NI 43-101 Technical Report ("Mount Milligan Mine TR") and results for nine months ended September 30, 2022, driven by the inflationary environment throughout 2022. Inflationary cost pressures have been noted in various areas of the Mount Milligan Mine's operations, mainly labour, energy and consumables such as grinding media, tires, equipment parts and diesel fuel.

The Company continues to optimize the life of mine plan for the Mount Milligan Mine and anticipates increases in both gold and copper production for 2024 and 2025 when compared to the annual figures included in the Mount Milligan Mine TR.

Exploration Expenditures
Exploration expenditures for 2023 are expected to be $35 to $45 million, including $10 million towards the Goldfield Project, approximately $13 to $17 million for brownfield exploration (Mount Milligan - $10 to $12 million and Öksüt - $3 to $5 million), and the balance for greenfield and generative exploration programs.

Other Material Assumptions
Other material assumptions used in forecasting production and costs for 2023 can be found under the heading "Caution Regarding Forward-Looking Information" in this document. Production, cost, and capital forecasts for 2023 are forward-looking information and are based on key assumptions and subject to material risk factors that could cause actual results to differ materially, and which are discussed under the heading "Material Risks" in the Company's most recent Annual Information Form.

The production information and other scientific and technical information presented in this document, including the production estimates, were prepared in accordance with the standards of the Canadian Institute of Mining, Metallurgy and Petroleum and National Instrument 43-101 Standards of Disclosure for Mineral Projects ("NI 43-101") and were prepared, reviewed, verified, and compiled by Centerra's geological and mining staff under the supervision of Paul Chawrun, P.Eng who is a member of the Professional Engineers Ontario and Centerra's Vice President and Chief Operating Officer, who is a qualified person for the purpose of NI 43-101.

The Mount Milligan deposit is described in a NI 43-101 technical report dated November 7, 2022 and filed on SEDAR at www.sedar.com. The technical report describes, amount other things, the exploration history, geology, and style of gold mineralization at the Mount Milligan deposit.

Non-GAAP and Other Financial Measures
This document contains "specified financial measure", denoted with NG, within the meaning of National Instrument 52-112 Non-GAAP and Other Financial Measures Disclosure of the Canadian Securities Administrators, specifically the non-GAAP financial measures. None of these specified financial measures are standardized financial measures under International Financial Reporting Standards ("IFRS") and these specified financial measures might not be comparable to similar financial measures disclosed by other issuers.

Management believes that the use of these non-GAAP measures assists analysts, investors and other stakeholders of the Company in understanding the costs associated with producing gold and copper, understanding the economics of gold and copper mining, assessing operating performance, the Company's ability to generate free cash flow from current operations and on an overall Company basis, and for planning and forecasting of future periods. However, the measures 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 other expenditures a company has to make to fully develop its properties. The specified financial measures used in this document do not have any standardized meaning prescribed by IFRS and may not 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. Accordingly, these specified financial measures should not be considered in isolation, or as a substitute for, analysis of the Company's recognized measures presented in accordance with IFRS.

Definitions

The following is a description of the non-GAAP measures used in this news release:

• All-in sustaining costs on a by-product basis per ounce is a non-GAAP ratio calculated as all-in sustaining costs on a by-product basis divided by ounces of gold sold. All-in sustaining costs on a by-product basis is a non-GAAP financial measure calculated as the aggregate of production costs as recorded in the consolidated statements of earnings, refining and transport costs, capitalized stripping and sustaining capital expenditures, lease payments related to sustaining assets, corporate general and administrative expenses, accretion expenses, asset retirement depletion expenses, copper and silver revenue and the associated impact of hedges of by-product sales revenue (added in the current period and applied retrospectively to the previous period). 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. A reconciliation of all-in sustaining costs on a by-product basis to the nearest IFRS measure is set out below. Management uses these measures to monitor the cost management effectiveness of each of its operating mines.
• All-in sustaining costs on a co-product basis per ounce of gold or per pound of copper, is a non-GAAP ratio calculated as all-in sustaining costs on a co-product basis divided by ounces of gold or pounds of copper sold, as applicable. All-in sustaining costs on a co-product basis is a non-GAAP financial measure based on an allocation of production costs between copper and gold based on the conversion of copper production to equivalent ounces of gold. The Company uses a conversion ratio for calculating gold equivalent ounces for its copper sales calculated by multiplying the copper pounds sold by estimated average realized copper price and dividing the resulting figure by estimated average realized gold price. For 2023, based on the assumed copper price of $3.25 per pound and assumed gold price of $1,600 per ounce, 492 pounds of copper was equivalent to one ounce of gold. A reconciliation of all-in sustaining costs on a co-product basis to the nearest IFRS measure is set out below. Management uses these measures to monitor the cost management effectiveness of each of its operating mines.
• All-in costs on a by-product basis per ounce is a non-GAAP ratio calculated as all-in costs on a by-product basis divided by ounces sold. All-in costs on a by-product basis is a non-GAAP financial measure which includes all-in sustaining costs on a by-product basis. exploration and study costs, non-sustaining capital expenditures, care and maintenance and predevelopment costs. A reconciliation of all-in costs on a by-product basis to the nearest IFRS measures is set out below. Management uses these measures to monitor the cost management effectiveness of each of its operating mines.
• Sustaining capital expenditures and Non-sustaining capital expenditures are non-GAAP financial measures. Sustaining capital expenditures are defined as those expenditures required to sustain current operations and exclude all expenditures incurred at new operations or major projects at existing operations where these projects will materially benefit the operation. Non-sustaining capital expenditures are primarily costs incurred at ?new operations' and costs related to ?major projects at existing operations' where these projects will materially benefit the operation. A material benefit to an existing operation is considered to be at least a 10% increase in annual or life of mine production, net present value, or reserves compared to the remaining life of mine of the operation. A reconciliation of sustaining capital expenditures and non-sustaining capital expenditures to the nearest IFRS measures is set out below. Management uses the distinction of the sustaining and non-sustaining capital expenditures as an input into the calculation of all-in sustaining costs per ounce and all-in costs per ounce.
