Centerra Year-End Gold Mineral Reserves and Mineral Resources

Mineral Reserves
As of December 31, 2022, Centerra's proven and probable gold mineral reserves total an estimated 5.45 million ounces (358 Mt at 0.46 g/t gold), compared to 5.93 million ounces (384 Mt at 0.52 g/t gold) in the prior year. In 2022, proven and probable gold mineral reserves decreased by 0.48 million ounces, due to depletion.

Mount Milligan Mine
At the Mount Milligan Mine, proven and probable gold mineral reserves total an estimated 2.6 million ounces of contained gold (224 Mt at 0.37 g/t gold) as of December 31, 2022, compared to 2.9 million contained ounces gold (246 Mt at 0.18 g/t gold) as at December 31, 2021 as stated in the Mount Milligan Mine TR. For 2022, proven and probable gold mineral reserves decreased by 0.3 million contained ounces of gold, due to depletion. A resource update is ongoing to include exploration drilling completed in 2022 and will be included in the 2023 mineral reserves and mineral resources update.

Öksüt Mine
At the Öksüt Mine, proven and probable gold mineral reserves total an estimated 0.9 million ounces of contained gold (27.1 Mt at 1.08 g/t gold) as at December 31, 2022, compared to the estimated 1.1 million ounces of contained gold (30.5 Mt at 1.16 g/t gold) as at December 31, 2021. The decrease of 0.2 million ounces in proven and probable gold mineral reserves in 2022 is primarily attributable to depletion. A resource update to include exploration drilling completed in 2022 is ongoing and will be included in the 2023 mineral reserves and mineral resources update.

A portion of the 2022 depletion at the Öksüt Mine can be attributed to processing ore into gold-in-carbon.

Goldfield Project
In the first quarter of 2022, the Company announced that it had entered into a definitive agreement to acquire the Goldfield Project from Waterton Nevada Splitter, LLC. The Goldfield Project consists of three known deposits: Gemfield, Goldfield Main, and McMahon Ridge. Centerra is targeting an initial resource estimate for the Goldfield Project by mid-year 2023 followed by an updated resource estimate accompanied by a Feasibility Study.

2022 Fourth Quarter Exploration Update

Exploration activities in the fourth quarter of 2022 included drilling, surface sampling, geological mapping and geophysical surveying at the Company's various projects and earn-in properties.

Exploration expenditures in the fourth quarter of 2022 and year were $16.2 million and $50.8 million, respectively. The activities were primarily focused on expanded drilling programs at the Mount Milligan Mine in British Columbia, the Öksüt Mine in Türkiye, the Goldfield Project in Nevada, and greenfield projects in Canada, the United States of America and Türkiye.

Mount Milligan Mine

The 2022 diamond drilling programs at the Mount Milligan Mine totalled 55,139 metres in 100 drill holes. Resource expansion and brownfield exploration targets included zones on the western margin of the open-pit, i.e., DWBX and Goldmark zones, and on the eastern margin of the open-pit, i.e., Great Eastern Fault ("GEF") zone, where positive drilling results were returned in previous drilling campaigns from 2018-2021.

Mount Milligan Brownfield Drilling and Exploration

Exploration and resource expansion drilling continued in the fourth quarter of 2022 with the completion of 27 diamond drill holes totalling 10,516 metres. Resource expansion drilling included 10 drill holes, totalling 2,513 metres, completed in the Great Eastern, 66, and DWBX zones. Six drill holes, totalling 1,143 metres, were completed in the Great Eastern zones, infilling shallow mineralization associated with the GEF. Additional infill drilling included three drill holes, totalling 1,065 metres, completed in the DWBX zone, and one drill hole, totalling 305 metres, completed in the 66 Zone. Exploration drilling was completed in five target areas and focused on the northern margins of the pit in the Oliver zone where six drill holes, totalling 2,061 metres, were completed. Exploration drilling was also completed south and west of the current ultimate pit boundary in the Boundary zone, including six drill holes totalling 2,786 metres; in the South Boundary zone, including one drill hole totalling 640 metres; in the Southern Star zone, including one drill hole totalling 605 metres; and in the North Slope zone, including three drill holes totalling 1,911 metres.

Throughout the fourth quarter of 2022, complete or partial assay results were returned for 38 drill holes, including results from 10 holes drilled in the third quarter of 2022, and 28 holes drilled in the fourth quarter of 2022. These include significant mineralized intervals from six target areas, including the western margin of the open-pit in the DWBX, North Slope, Boundary, and South Boundary zones, the eastern margin of the open-pit in the Great Eastern zone, and the northern margin of the open-pit in the Oliver zone.

Assays returned throughout the fourth quarter of 2022 include results from infill drilling in the DWBX and GEF zones, showing potential for both shallow and deep resource addition west and east of the ultimate pit boundary. In the DWBX zone, porphyry-style gold-copper mineralization is associated with potassic alteration and early quartz veins within the DWBX composite stock and the stock margins. A moderately west-dipping hydrothermal breccia body has been identified at shallow depth in host volcanic rocks in the northern part of the DWBX zone, interpreted to have formed during stock emplacement. In the GEF zone on the eastern ultimate pit margins, shallow drilling has defined a tabular body of gold and copper mineralization within the hanging wall of the easterly dipping GEF.

Exploration drilling in the North Slope zone, approximately 1,000 to 1,600 metres from the western margins of the ultimate pit boundary, was completed in the fourth quarter of 2022. Assays returned throughout the fourth quarter of 2022 show porphyry-style gold and copper mineralization at depth, associated with a series of narrow dykes, referred to as the North Slope dyke complex. Mineralization is associated with increased density of early, transitional, and late-stage veins in potassic (magnetite-biotite) and inner propylitic (albite-epidote-chlorite) altered volcanics and volcaniclastics.

Exploration drilling in the Boundary zone, approximately 350 metres from the western margins of the ultimate pit boundary, was completed in the fourth quarter of 2022. Assays returned throughout the fourth quarter of 2022 show shallow and deep porphyry-style gold and copper mineralization associated with a series of monzonite ± hornblende porphyry dykes in the shallow Boundary zone and underlying northwestern extension of the Southern Star composite stock. Mineralization is hosted within dykes and at dyke margins in potassic (magnetite-biotite) and inner propylitic (albite-epidote-chlorite) altered andesite tuffs, often overprinted by quartz-sericite-pyrite alteration, with early quartz veins and chalcopyrite ± pyrite veins.

Exploration drilling in the Oliver zone, along the northwestern margins of the ultimate pit boundary was completed in the fourth quarter of 2022. Assays returned throughout the fourth quarter of 2022 show potential for deep resource addition adjacent to and below the current ultimate pit boundary. Significant intersections with high gold-low copper mineralization are hosted within quartz-sericite-pyrite altered bedded trachyte tuff with pyrite ± chalcopyrite ± calcite veins. Porphyry-style gold and copper mineralization at depth is hosted by potassic (magnetite-biotite) altered latite crystal tuff overprinted by quartz-sericite-pyrite alteration, with early quartz veins and pyrite ± chalcopyrite veins.

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 SEDAR at www.sedar.com, EDGAR at www.sec.gov/edgar, are available on the Company's website at www.centerragold.com and are available at the following link: http://ml.globenewswire.com/Resource/Download/b61c87e0-4c7e-40d5-b040-84433dc640fe

Goldfield Project

Drill programs at the Goldfield Project commenced in June 2022, following the purchase of the project in February 2022. The 2022 diamond drilling and RC drilling programs included 149 exploration, infill, and resource expansion holes, 16 metallurgical holes, 17 geotechnical holes, 22 condemnation holes, and two water monitoring wells. Exploration drilling in 2022 principally targeted gold mineralization below and adjacent to the known mineralization at the Gemfield and Goldfield Main deposits. As of the end of 2022, a total of 48,765 metres of drilling was completed in 206 drill holes (200 holes were completed and six holes were abandoned due to ground conditions).

At the Goldfield Project, 21 diamond drill holes and 134 RC drill holes, totalling 35,259 metres of drilling, were completed during the fourth quarter. Completed holes include 26,590 metres in 117 exploration, infill, and resource expansion holes, 3,995 metres in 18 condemnation drill holes, 2,920 metres in 10 metallurgical holes, 1,512 metres in eight geotechnical holes, and two water monitoring wells for 241 metres.

Gemfield Deposit
The planned 2022 drilling programs at the Gemfield deposit totalled 29,279 metres in 25 diamond drill holes and 105 RC drill holes for a total of 130 drill holes. Drilling activities in the fourth quarter of 2022 at the Gemfield deposit consisted of two diamond drill holes and 86 RC holes totalling 17,287 metres. Drilling was generally undertaken around the margins of and within the confines of the known mineralization at the Gemfield deposit.

As of the end of the fourth quarter, complete or partial assay results were returned for 57 drill holes at the Gemfield deposit, including results from holes drilled in the second, third, and fourth quarters of 2022.

Assay results from the 2022 exploration drilling at the Gemfield deposit identified extensions to known gold mineralization to the west and south of the deposit. This mineralization is relatively deep and forms broad zones of low-grade gold mineralization. This gold mineralization is associated alteration with quartz-alunite alteration with sulfides, mainly pyrite. Preliminary metallurgical test work (shake tests and bottle roll tests) has commenced and is ongoing. Resource expansion drilling peripheral to the eastern and northeastern margins of the known mineralization intersected shallow, oxidized gold mineralization, some of which lies beneath the historic Consolidated Mill tailings pile. Oxidation at the Gemfield deposit is generally no deeper than 90 metres but can extend deeper depending on the thickness and depth of erosion of an overlying, post-mineral sedimentary unit, the Siebert Formation.

Goldfield Main Deposit
The 2022 drilling programs at the Goldfield Main Deposit totalled 19,121 metres in 26 diamond drill holes and 48 RC drill holes for a total of 74 drill holes. Drilling activities in the fourth quarter of 2022 at the Goldfield Main deposit consisted of 17 diamond drill holes and 48 RC holes totalling 17,606 metres. Drilling was generally undertaken around the margins of and within the confines of the known mineralization at the Goldfield Main deposit.

As of the end of the fourth quarter, complete or partial assay results were returned for 10 drill holes at the Goldfield Main deposit, including results from holes drilled in the second, third, and fourth quarters of 2022. The gold mineralization encountered is consistent with nearby historic drill intervals, confirming and slightly expanding the known mineralization along the splay structures present within the Goldfield Main deposit. Infill drilling also confirmed that oxidation is relatively shallow but extends deeper along the Columbia Fault and the secondary splay structures present within the deposit.

McMahon Ridge Deposit
Drilling activities commenced in the fourth quarter of 2022 at the McMahon Ridge deposit. Two diamond drill holes, totalling 366 metres, were drilled for geotechnical purposes. Assay results are awaited.

Öksüt Mine

The planned 2022 diamond and RC drilling programs were completed at the Öksüt Mine in the fourth quarter with 122 diamond holes, totaling 31,787 metres, and 40 RC drill holes, totaling 7,465 metres, being completed for an aggregate of 39,252 metres of drilling. In the fourth quarter, 21 diamond holes, totaling 5,495 metres, and 21 RC drill holes, totaling 3,841 metres, were completed for an aggregate of 9,336 metres of drilling. Drilling in the fourth quarter focused on targeting the potential expansion of oxide gold mineralization at the Keltepe, Güneytepe, Keltepe North, Keltepe Northwest, and Keltepe North Northwest deposits as well as testing the potential for new oxide gold mineralization at peripheral targets such as the Yelibelen, Büyüktepe, and Boztepe prospects.

As of the end of the fourth quarter, complete or partial assay results were returned for 94 drill holes at the Öksüt Mine, including results from holes drilled in the second, third, and fourth quarters of 2022. Generally, relatively narrow and low to moderate grade oxide gold intervals were returned from drilling in 2022.

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 Öksüt Mine have been filed on SEDAR at www.sedar.com, EDGAR at www.sec.gov/edgar, are available on the Company's website at www.centerragold.com and are available at the following link: http://ml.globenewswire.com/Resource/Download/b61c87e0-4c7e-40d5-b040-84433dc640fe

Caution Regarding Forward-Looking Information
Information contained in this news release, which are not statements of historical facts, and the documents incorporated by reference herein, may be "forward-looking information" for the purposes of Canadian securities laws. Such forward-looking information involves risks, uncertainties, and other factors that could cause actual results, performance, prospects, and opportunities to differ materially from those expressed or implied by such forward-looking information. The words "believe", "expect", "anticipate", "contemplate", "target", "plan", "intends", "continue", "budget", "estimate", "may", "will", "schedule", and similar expressions identify forward-looking information. These forward-looking statements relate to, among other things, mineral reserve and mineral resource estimates, life of mine estimates and operating and capital costs, future exploration potential, timing and scope of future exploration (brownfields or greenfields), and anticipated costs and expenditures and other information that is based on forecasts of future operational or financial results, estimates of amounts not yet determinable, and assumptions of management. Forward-looking information is necessarily based upon a number of estimates and assumptions that, while considered reasonable by Centerra, are inherently subject to significant political, business, economic, and competitive uncertainties and contingencies. Known and unknown factors could cause actual results to differ materially from those projected in the forward-looking information. For a full list of the risk factors that can affect the Company, see its management's discussion and analysis for the year ended December 31, 2022, and its most recently filed annual information form.

Market price fluctuations in gold, copper, and other metals, as well as increased capital or production costs or reduced recovery rates may render ore reserves containing lower grades of mineralization uneconomic and may ultimately result in a restatement of mineral reserves. The extent to which mineral resources may ultimately be reclassified as proven or probable mineral reserves is dependent upon the demonstration of their profitable recovery. Economic and technological factors, which may change over time, always influence the evaluation of mineral reserves or mineral resources. Centerra has not adjusted mineral resource figures in consideration of these risks and, therefore, Centerra can give no assurances that any mineral resource estimate will ultimately be reclassified as proven and probable mineral reserves.

Mineral resources are not mineral reserves, and do not have demonstrated economic viability, but do have reasonable prospects for economic extraction. Measured and indicated mineral resources are sufficiently well defined to allow geological and grade continuity to be reasonably assumed and permit the application of technical and economic parameters in assessing the economic viability of the resource. Inferred mineral resources are estimated on limited information not sufficient to verify geological and grade continuity or to allow technical and economic parameters to be applied. Inferred mineral resources are too speculative geologically to have economic considerations applied to them to enable them to be categorized as mineral reserves. There is no certainty that mineral resources of any category can be upgraded to mineral reserves through continued exploration.

Centerra's mineral reserve and mineral resource figures are estimates, and Centerra can provide no assurances that the indicated levels of gold or copper will be produced, or that Centerra will receive the metal prices assumed in determining its mineral reserves. Such estimates are expressions of judgment based on knowledge, mining experience, analysis of drilling results, and industry practices. Valid estimates made at a given time may significantly change when new information becomes available. While Centerra believes that these mineral reserve and mineral resource estimates are well established, and the best estimates of Centerra's management, by their nature mineral reserve and mineral resource estimates are imprecise and depend, to a certain extent, upon analysis of drilling results and statistical inferences, which may ultimately prove unreliable. If Centerra's mineral reserve or mineral reserve estimates for its properties are inaccurate or are reduced in the future, this could have an adverse impact on Centerra's future cash flows, earnings, results, or operations and financial condition.

Centerra estimates the future mine life of its operations. Centerra can give no assurance that mine life estimates will be achieved. Failure to achieve these estimates could have an adverse impact on Centerra's future cash flows, earnings, results of operations, and financial condition.

There can be no assurances that forward-looking information and statements will prove to be accurate, as many factors and future events, both known and unknown, could cause actual results, performance, or achievements to vary or differ materially from the results, performance, or achievements that are, or may be, expressed or implied by such forward-looking statements contained herein or incorporated by reference. Accordingly, all such factors should be considered carefully when making decisions with respect to Centerra, and prospective investors should not place undue reliance on forward-looking information. Forward-looking information is as of February 24, 2023. Centerra assumes no obligation to update or revise forward-looking information to reflect changes in assumptions, changes in circumstances, or any other events affecting such forward-looking information, except as required by applicable law.
