Refer to Tables “Centerra Gold Inc. 2024 Year-End Mineral Reserve and Resource Summary – Gold” and “Centerra Gold Inc. 2024 Year-End Mineral Reserve and Resource Summary – Other Metals”, including their respective footnotes and the “Additional Footnotes” section below. Mount Milligan Mine (“Mount Milligan”): In 2024, the Company replaced mined mineral reserves at Mount Milligan by upgrading mineral resources. Centerra has successfully extended the life of mine at Mount Milligan to 2036 by increasing the use of mined-out areas of the open pit for potential acid generating (“PAG”) waste storage. This has increased available storage capacity in the existing tailings facility and extended the overall mine life for the current mineral reserve estimate. Kemess Project (“Kemess”): The Kemess property has substantial gold and copper resources in a highly prospective district with significant infrastructure already in place, including: a 300 kilometre, 230 kilovolt power line, one of the longest privately owned power lines in British Columbia; a 50,000 tonnes per day nameplate processing plant, which would require some refurbishment and equipment replacements; site infrastructure including a camp, administration facilities, truck shop and warehouse; and tailings storage through in-pit and an existing facility, which is capable of expansion. Centerra is currently working to incorporate the results of a drilling campaign conducted in 2024 at Kemess into an updated open pit resource model. The program included over 11,400 metres of core drilling for exploration, geotechnical, and metallurgical testing purposes. During 2024, Centerra commenced evaluation of technical concepts and engineering trade-off studies for potential restart options at Kemess. Early operating concepts include a combined open pit and conventional underground operation, which are expected to be less capital intensive and have a better cash flow profile than the previously permitted underground block cave concept. In addition to an exploration campaign in 2025 to further delineate the resources, the Company is planning on continuing to advance the technical studies that will include metallurgical testing for flowsheet optimization, mine plan optimization, materials handling infrastructure engineering, tailings design optimization, as well as initiation of environmental baseline studies. Early indications show potential for a long-life operation that takes advantage of the significant infrastructure already in place. The Company expects to provide an updated resource estimate and an accompanying update on the technical concept for Kemess in the second quarter of 2025. Story Continues Goldfield: The initial measured and indicated gold mineral resource at Goldfield was 706 thousand ounces of gold, as of December 31, 2024, which includes both oxide and transition material, principally in the Gemfield, McMahon, and Jupiter deposits. In conjunction with exploration drilling, the Company completed metallurgical testwork resulting in run-of-mine recoveries in the mid-60% range (see “Additional Footnotes” section at the end of this release for details on recoveries), which is in line with expectations for a heap leach project and is expected to lower the capital investment required for the project. Based on the size of the resource estimate, the project does not meet Centerra’s requirements to support near-term development. The Company remains committed to maximizing the project’s potential, while exploring strategic and commercial options for Goldfield.

Exploration Update Exploration activities in the fourth quarter of 2024 included drilling, surface rock and soil sampling, geological mapping, and geophysical surveying, targeting gold and copy mineralization at the Company’s projects and properties in Canada, Türkiye, and the United States. 2024 Exploration Highlights Confirming Mount Milligan’s long-life potential, the pit expanded to the west and southwest, due to significant intersections in the Goldmark and Saddle areas. Model expansion includes the south boundary area. Remodeling considers all holes drilled west of the Mount Milligan pit and resulted in defining the South Boundary inferred resource. At Kemess drilling was carried out in 2024 to assess the viability of start-up scenarios and open pit resource expansion. The goal was to expand near-surface mineralization west and southwest of the Kemess underground project. Resource delineation drilling for near surface oxide mineralization continued at the Goldfield project. Drilling intersected low-grade mineralization with a series of 10 to 30 metres at 0.4 grams per tonne (“g/t”). Most of the drilling was completed before the fourth quarter 2024, except at the Oakley project, in Idaho, United States (5,818 metres), Nallihan in Türkiye (4,829 metres) and Öksüt in Türkiye (421 metres). The drilling at Öksüt started late December 2024. Full year 2024 drilling totalled 72.3 kilometres, including greenfield projects. 2025 Exploration Outlook Exploration expenditures in 2025 are expected to be $35 to $45 million, including $20 to $25 million of brownfield exploration primarily at Mount Milligan and Kemess, and $15 to $20 million of greenfield and generative exploration programs. Centerra is expected to continue to explore the western extension of the Mount Milligan deposit and perform infill drilling to upgrade the inferred resources to indicated. Approximately 25% of the 2025 exploration expenditures are allocated to drilling programs at Mount Milligan to upgrade the inferred resources between Goldmark and North Slope and to test the extension of the South Boundary mineralization. A total of 45 kilometres of drilling is planned for 2025 at Mount Milligan. Centerra is expected to continue to explore Kemess, where the 2024 drilling resulted in delineation of mineralization between the Kemess Main open pit and Nugget (Centra Ridge zone). The 2025 exploration program at Kemess is focused on upgrading the resources along the five-kilometre-long mineralized trend. Approximately 13% of the 2025 exploration expenditures are allocated to Kemess to drill 12.5 kilometres. In the United States, Centerra is expected to continue to explore for near surface oxide mineralization within the Goldfield district and at Oakley. Centerra is also expected to continue advancing exploration work at its greenfield projects, Green Springs in Nevada and Jones Creek in Utah. In Türkiye, Centerra is expected to commence phase 2 drilling at the Nallihan joint venture project and to continue to explore for near surface mineralization southeast of the Öksüt pit. Mount Milligan In 2024, the Company replaced mined mineral reserves at Mount Milligan by upgrading mineral resources. Ongoing exploration drilling program at the site is aimed at expanding the mineral resource base significantly to the west and southwest. In 2024, a total of 7,176 metres of infill drilling was completed in 25 drillholes, and 12,403 metres of brownfield exploration drilling was completed in 28 drillholes. Brownfield exploration focused on targets west of the current ultimate pit margins including the North Slope, Saddle West, and Boundary zones. The 2024 exploration drill results at the North Slope zone show potential for shallow as well as deep porphyry mineralization west of the ultimate pit boundary, adjacent to the Goldmark zone. Results from infill drilling in the MBX zone shows potential for resource expansion on the western pit wall margins and below the current pit boundary. The inclusion of all drillholes west of the Mount Milligan pit in the updated resource model resulted in the delineation of a potential satellite pit at south boundary. This area is one of the focus areas in the 2025 drilling campaign. Centerra continues to be encouraged by the significant mineral endowment and the potential for future resource additions at Mount Milligan. The Company is expected to invest approximately $9 to $12 million in exploration at Mount Milligan in 2025.

Drilling started in January 2025. The DWBX zone is the depth extension of the WBX porphyry-style gold-copper mineralisation currently mined in the pit. Mineralization is associated with potassic alteration and early quartz veins within the DWBX stock and stock margins. Near surface and south of the DWBX is the King Richard zone. Results received to-date show the potential to extend the open pit to mine DWBX, King Richard, and DWBX Extension. Some selected significant results received during the year include: Hole #24-1531: 26.0m @ 0.71 g/t Au, 0.188% Cu from 58m Hole #24-1569: 37.8m @ 0.48 g/t Au, 0.229% Cu from 115m Hole #24-1572: 30.3m @ 0.55 g/t Au, 0.176% Cu from 83m Hole #24-1556: 48.4m @ 0.32 g/t Au, 0.204% Cu from 139m Hole #24-1571: 58.0m @ 0.24 g/t Au, 0.068% Cu from 68m Hole #24-1556: 83.8m @ 0.15 g/t Au, 0.127% Cu from 214m Hole #24-1554: 73.0m @ 0.16 g/t Au, 0.168% Cu from 248m Hole #24-1564: 18.7m @ 0.60 g/t Au, 0.161% Cu from 21m The Goldmark zone is directly west of the current Mount Milligan pit design, situated above the high grade DWBX zone. In 2024, drilling continued to test the western extent of the Goldmark mineralisation that had been intersected in previous drill programs. Shallow porphyry-style gold and copper mineralisation is hosted at the margins of dykes and the Goldmark stock. High gold-low copper (“HGLC”) style mineralisation occurs throughout the zone. The results show potential for shallow resource additions and the extension of mineralisation west of the existing pit boundary. Significant results include: Hole #24-1529: 65.0m @ 0.22 g/t Au, 0.191% Cu from 497m Hole #24-1529: 19.2m @ 0.41 g/t Au, 0.038% Cu from 370m Hole #24-1532: 20.0m @ 0.28 g/t Au, 0.030% Cu from 34m Hole #24-1532: 11.5m @ 0.32 g/t Au, 0.205% Cu from 275m The North Slope zone is approximately 1.5 kilometres west of the western margins of the existing pit boundary. Assays show multiple localized shallow zones of mineralisation related to the North Slope stock, with higher-grade porphyry-style gold and copper mineralization intersected near surface and at depth. Significant results include: Hole #24-1533: 42.3m @ 0.41 g/t Au, 0.241% Cu from 25m Hole #24-1533: 3.0m @ 4.47 g/t Au, 0.078% Cu from 448m Hole #24-1536: 41.8m @ 0.33 g/t Au, 0.144% Cu from 244m Hole #24-1536: 68.6m @ 0.16 g/t Au, 0.172% Cu from 305m Hole #24-1536: 64.9m @ 0.29 g/t Au, 0.173% Cu from 378m Hole #24-1543: 85.8m @ 0.24 g/t Au, 0.173% Cu from 336m Hole #24-1543: 101.3m @ 0.20 g/t Au, 0.179% Cu from 451m Hole #24-1563: 7.1m @ 2.21 g/t Au, 0.142% Cu from 81m Hole #24-1563: 13.5m @ 1.09 g/t Au, 0.086% Cu from 32m Hole #24-1566: 4.9m @ 8.11 g/t Au, 0.024% Cu from 238m Hole #24-1566: 40.0m @ 0.33 g/t Au, 0.012% Cu from 136m Hole #24-1567: 23.5m @ 4.27 g/t Au, 0.183% Cu from 160m Hole #24-1567: 5.0m @ 5.01 g/t Au, 0.147% Cu from 291m Hole #24-1567: 27.0m @ 2.83 g/t Au, 0.143% Cu from 342m Hole #24-1567: 27.7m @ 3.63 g/t Au, 0.129% Cu from 483m Kemess Project In 2024, 11,430 metres of core drilling was completed in 31 drillholes. These drillholes are expected to be incorporated into an updated mineral resource in the second quarter of 2025. The 2024 drill program targeted the area between the known mineralization at Nugget and the upper portion of the Kemess Underground zones. Significant drill intersections were received, confirming that the mineralization continues approximately five kilometres along strike. Geologic modeling and a preliminary resource estimate show continuous mineralization between the Nugget and Kemess North zone areas, which is expected to be the focus for the 2025 drill program. The program aims to upgrade inferred resources to indicated reserves and also to test, and potentially, confirm high grade mineralization in the deep Kemess offset zone. Centerra is encouraged by the large mineralization at Kemess and believes that it can be a future source of gold and copper production with a long mine life. Some of the significant 2024 results include: Hole #KN-24-013: 435m @ 0.43g/t Au, 0.23% Cu from 172m Hole #KN-24-013: 402m @ 0.42g/t Au, 0.20% Cu from 47m Hole #KN-24-017: 382m @ 0.38g/t Au, 0.19% Cu from 8m Hole #KN-24-014: 342m @ 0.35g/t Au, 0.07% Cu from 56m Hole #KN-24-019: 341m @ 0.34g/t Au, 0.16% Cu from 4m Hole #KN-24-021: 311m @ 0.37g/t Au, 0.18% Cu from 0m Figure 6: A long sectional view of the Kemes deposit showing a 0.2 g/t Au shell.

The 2023 conceptual optimized pit is shown in grey. Goldfield Project (“Goldfield”) In 2024, Centerra continued to explore within the Goldfield district, focusing on exploring near surface oxide mineralization. The 2024 drill program consisted of 175 drillholes over 20,028 metres with 45 core holes totaling 5,386 metres and 130 reverse circulation drillholes totaling 14,642 metres. Drilling at Goldfield’s other target areas did not yield meaningful results. The Jupiter prospect exploration program focused on oxidized mineralization with an up-dip projection trending shallower on the eastern portion of the prospect. The Jupiter prospect is the northerly extension of the Gemfield deposit. Drilling was facilitated by land agreements and drill permits completed in late 2023. Results proved the up-dip projection of oxide mineralization in the prospect, however, the grades and thickness are uneconomic to include an appreciable amount of material into an optimized pit shell when the prevailing economic parameters were applied. A series of small satellite pits were delineated to be included in the Goldfield initial resource. Some of the significant results received for Jupiter include: Hole #GEM24R279: 19.8m @ 2.55 g/t Au, 16.38 g/t Ag from 87m Hole #GEM24R256: 36.6m @ 1.04 g/t Au, 1.09 g/t Ag from 20m Hole #GEM24R319: 6.1m @ 5.36 g/t Au, 5.50 g/t Ag from 0m Hole #GEM24R286: 24.4m @ 1.09 g/t Au, 1.96 g/t Ag from 23m Hole #GEM24R249: 35.1m @ 0.41 g/t Au, 0.66 g/t Ag from 40m Hole #GEM24R291: 30.5m @ 0.46 g/t Au, 0.70 g/t Ag from 15m Hole #GEM24R289: 30.5m @ 0.40 g/t Au, 0.91 g/t Ag from 15m Hole #GEM24R239: 32.0m @ 0.38 g/t Au, 1.04 g/t Ag from 11m Oakley Project (“Oakley”) The 2024 drill program at Oakley completed 32 drillholes over 5,818 metres with 18 core holes totaling 2,995 metres and 14 reverse circulation drillholes totaling 2,823 metres. In 2024, drilling at the Cold Hill and Blue Hill prospects focused on expanding the known gold mineralization, while drilling at Red Rock and White Rock focused on new, untested drill targets. At the Cold Hill target, four holes encountered significant mineralization, primarily represented by silicified pebble to cobble conglomerate and silicified volcanic ash, and with minor intersections within the underlying Paleozoic limestone, represented by decalcification and silicification. These intersections continue to define the lateral extent and width of the mineralization at Cold Hill. Some of the significant results received for Cold Hill include: Hole #CC-24-04: 20.3m @ 0.24 g/t Au, 1.47 g/t Ag from 8m Hole #CC-24-04: 20.9m @ 0.50 g/t Au, 4.00 g/t Ag from 37m Hole #CC-24-07: 9.9m @ 0.69 g/t Au, 1.19 g/t Ag from 192m Hole #CC-24-07: 1.0m @ 4.54 g/t Au, 0.90 g/t Ag from 200m Drilling at the Blue Hill prospect focused on testing the margins of the known mineralization and following up on the higher-grade intersections identified in historic drilling. Mineralization was encountered in the most southwestern drillholes in the prospect, which shows the potential for additional mineralization towards the southwest. The mineralization is associated with strong silicification of the pebble to cobble conglomerate and silicification of the volcanic ash beds. Significant intersections are listed below. Hole #BHC24R001: 19.8m @ 0.42 g/t Au, 4.19 g/t Ag from 24m Hole #BHC24R003: 24.4m @ 0.45 g/t Au, 4.73 g/t Ag from 84m Hole #BHC24R005: 64.0m @ 0.31 g/t Au, 2.74 g/t Ag from 50m Hole #BHC24R005: 28.9m @ 0.25 g/t Au, 6.88 g/t Ag from 131m Hole #BHC24R007: 21.4m @ 0.35 g/t Au, 3.11 g/t Ag from 90m Hole #BHC24R007: 67.0m @ 0.50 g/t Au, 5.83 g/t Ag from 162m Öksüt Mine (“Öksüt”) Drilling started during December 2024, with a total of 431 metres completed at the Güneytepe pit to test for potential deep porphyry mineralization. The exploration for deep porphyry deposits was initiated in 2023, based on historical drillholes confirming potassic alteration related to porphyry intrusive rocks on the Öksüt license. In 2024, a detailed alteration analysis and modelling was completed, using data from historical and recent (2023) deep holes drilled in and around the Öksüt deposit. The analysis of these drillholes pointed to the presence of a large pyrophyllite alteration zone, which is an indicator for the presence of the upper parts of a porphyry system. The porphyry system was tested in 2024 by drilling additional deep holes under the Güneytepe pit.

Caution Regarding Forward-Looking Information This news release contains or incorporates by reference “forward-looking statements” and “forward-looking information” as defined under applicable Canadian and U.S. securities legislation. All statements, other than statements of historical fact, which address events, results, outcomes or developments that the Company expects to occur are, or may be deemed to be, forward-looking statements. 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. Forward-looking statements are generally, but not always, identified by the use of forward-looking terminology such as “assume”, “believes”, “continue”, “encouraged”, “estimate”, “expect”, “future”, “ongoing”, “plan”, “potential”, “target” or “update”, or variations of such words and phrases and similar expressions or statements that certain actions, events or results “may”, “could”, “would” or “will” be taken, occur or be achieved or the negative connotation of such terms. Such statements include but may not be limited to: 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); the ability of the Company to increase mineral reserves or mineral resources at any of its properties; the future success of Kemess including the results of an updated resource estimate and accompanying update on its technical concept including mining methods; the ability of the Company to achieve 50,000 tonnes per day at the Kemess processing plant; the ability of the Company to expand the existing tailings facility at Kemess; and other statements that express management’s expectations or estimates of future plans and performance, operational, geological or financial results, estimates or amounts not yet determinable and assumptions of management. The Company cautions that forward-looking statements are necessarily based upon a number of factors and assumptions that, while considered reasonable by the Company at the time of making such statements, are inherently subject to significant business, economic, technical, legal, political and competitive uncertainties and contingencies. Known and unknown factors could cause actual results to differ materially from those projected in the forward-looking statements and undue reliance should not be placed on such statements and information. 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. Additional risk factors and details with respect to risk factors that may affect the Company’s ability to achieve the expectations set forth in the forward-looking statements contained in this news release are set out in the Company’s latest 40-F/Annual Information Form and Management’s Discussion and Analysis, each under the heading “Risk Factors”, which are available on SEDAR+ (www.sedarplus.ca) or on EDGAR (www.sec.gov/edgar). The foregoing should be reviewed in conjunction with the information, risk factors and assumptions found in this news release. The Company disclaims any intention or obligation to update or revise any forward-looking statements, whether written or oral, or whether as a result of new information, future events or otherwise, except as required by applicable law.
