  • Mount Milligan: Centerra entered into an additional agreement with RGLD Gold AG, a subsidiary of Royal Gold, Inc., relating to Mount Milligan, which immediately extends the mine life by two years to 2035 and grows the mineral resources to 510 million tonnes, inclusive of reserves. For additional details, please refer to the announcement entitled “Centerra Gold Announces Mount Milligan Mine Life Extension and New Agreements with Royal Gold”, which was issued in conjunction with this news release on February 14, 2024.
  • Kemess: The Kemess underground block cave project is not a priority for Centerra’s project pipeline at this time. The prior mineral reserves and resources estimate produced for this project were completed with costs and commodity price assumptions that are no longer applicable. As a result, the Company has applied current capital, operating and metal price assumptions to reclassify the historical reserves as a blend of open pit and underground resources. Confirmation and exploration drilling, as well as technical studies are planned for 2024 and are expected to provide an updated mining and processing concept which may unlock additional value. Kemess benefits from infrastructure already on site, several permits in place, and an impact benefit agreement with its First Nation partners. Centerra remains optimistic that Kemess could be a future source of gold and copper production.

  • Berg: In December 2023, Centerra entered into an agreement to sell its 100% interest in the Berg Property to Surge Copper Corp., which was completed in January 2024. Surge had been earning into a 70% interest in the Berg Property, and following the sale, Centerra holds approximately 15% of Surge’s outstanding common shares. As a result, Berg is not included in Centerra’s overall copper resources at the end of 2023.

Exploration Update

Exploration activities in the fourth quarter of 2023 included drilling, surface rock and soil sampling, geological mapping, and geophysical surveying, targeting gold and copper mineralization at the Company’s projects and properties in Canada, Türkiye, and the United States.

2023 Exploration Highlights

  • Significant mineral endowment at Mount Milligan sets the stage for potential future resource additions, including possibilities for near-surface additions and depth extensions.
  • Resource delineation for oxide and transition material continued at the Goldfield project, with emphasis on extending known mineralization from the Gemfield deposit.
  • Positive initial results at the Oakley project early in 2023 warranted a follow up drilling campaign.
  • Fourth quarter of 2023 drilling program included 7,967 metres of drilling.
  • Full year 2023 drilling totalled 94.7 kilometres, including greenfield projects.

2024 Exploration Outlook

  • Pursue further exploration activities to identify potential extensions and enhancements to existing resources at Mount Milligan.
  • Commence drill test programs at all identified target areas in Canada, United States, and Türkiye.
  • Continue with advanced exploration activities at Goldfield and Oakley.
  • Exploration expenditures in 2024 are expected to be $35 to $45 million, including $17 to $22 million of brownfield exploration, and $18 to $23 million of greenfield and generative exploration programs.

Mount Milligan Mine (“Mount Milligan”)

  • Ongoing exploration drilling program at Mount Milligan aimed at expanding the mineral resource base significantly.
  • In 2023, 80% of exploration drilling focused on the pit and three brownfield areas, revealing mineralization in tested areas west of the pit margin and below the ultimate pit boundary.
  • Goldmark, Boundary and South Boundary present possibilities for near-surface additions, while North Slope, DWBX Extension, and Saddle West are being tested for depth extensions.
  • Encouraged by the significant mineral endowment and potential future resource additions at Mount Milligan, Centerra plans to invest approximately $5 to $7 million in exploration at Mount Milligan in 2024.

Mount Milligan Brownfield Drilling and Exploration

The DWBX zone is the depth extension of the WBX porphyry-style gold-copper mineralization currently mined in the pit. Mineralization is associated with potassic alteration and early quartz veins within the DWBX stock and stock margins. Results received to-date show the depth extension of the mineralization and potential to extend the pit to mine DWBX and DWBX Extension. Some selected significant results received during the year include:

Hole #23-1475 : 51.6m @ 0.73 g/t Au, 0.047% Cu from 335m
Hole #23-1484 : 50.7m @ 1.60 g/t Au, 0.177% Cu from 173m
Hole #23-1484 : 72.0m @ 0.65 g/t Au, 0.202% Cu from 447m
Hole #23-1487 : 157.6m @ 0.23g/t Au, 0.035% Cu from 271m

The Goldmark zone is directly west of the current Mount Milligan pit design, situated above the high grade DWBX zone. Drilling during the year aimed to test the western extent of the Goldmark mineralization that had been intersected in previous drilling programs. Shallow porphyry-style gold and copper mineralization is hosted at the margins of dykes and the Goldmark stock. High gold-low copper (“HGLC”) style mineralization occurs throughout the zone. The results show potential for shallow resource addition and the extension of mineralization west of the existing pit boundary. Significant results include:

Hole #23-1480 : 55.5m @ 1.55 g/t Au, 0.026% Cu from 13m
Hole #23-1481 : 90.2m @ 0.49 g/t Au, 0.054% Cu from 419m
Hole #23-1485 :132.0m @ 0.25 g/t Au, 0.192% Cu from 366m

The North Slope zone is approximately 1.5 kilometres from the western margins of the existing pit boundary. Assays returned show localized shallow zones of low-grade gold and copper mineralization related to the North Slope stock, with higher-grade porphyry-style gold and copper mineralization at depth. Significant results include:

Hole #23-1491 : 58.0m @ 0.17 g/t Au, 0.102% Cu from 443m
Hole #23-1493 : 50.5m @ 0.19 g/t Au, 0.219% Cu from 489m
Hole #23-1503 : 43.8m @ 0.21 g/t Au, 0.303% Cu from 439m

The Saddle zone and the Saddle West zone are south of Goldmark, along the western margins and within one kilometre of the current pit boundary. The program was designed for resource expansion, targeting extension of deep HGLC mineralization below the current pit. Results returned show potential for deep resource addition adjacent to and below the current pit boundary. Significant results include:

Hole # 23-1470 : 61.0m @ 0.895 g/t Au, 0.005% Cu from 476m
Hole # 23-1467 : 106.7m @ 0.259 g/t Au, 0.023% Cu from 344m
Hole #23-1471 : 12.3m @ 1.45g/t Au ; 0.022% Cu from 498m

The Boundary zone is within 500 metres of the western margins of the Southern Star pit boundary. Assays returned show shallow and deep porphyry-style gold and copper mineralization associated with dykes in the Boundary zone and the extension of the Southern Star stock at depth. Mineralization is associated with potassic and propylitic alteration, often overprinted by quartz-sericite-pyrite alteration, with early quartz veins and chalcopyrite ± pyrite veins. Significant results include:

Hole #23-1514 : 25.0m @ 0.152 g/t Au, 0.181% Cu from 129m
Hole #23-1509 : 73.7m @ 0.336 g/t Au, 0.066% Cu from 215.3m
Hole #23-1510 : 42.4m @ 0.202 g/t Au, 0.322% Cu from 511.6m
Hole #23-1507 : 35.6m @ 0.219 g/t Au, 0.216% Cu from 455m

In addition to the east-west corridor, drill testing was carried out within the southwest-northeast corridor at M6 and Orica, both targets were interpreted as linking to the Southern Star pit. M6 and Orica drill testing zones are approximately 1.5 kilometre west and southwest respectively from the western margins of the Southern Star ultimate pit boundary. Results received show mineralization potential in a relatively underexplored area, especially to the southwest. The porphyry-style gold and copper mineralization in these target areas are expected to be part of the focus in 2024.

Goldfield Project (“Goldfield”)

  • Goldfield achieved 49 kilometres of drilling in 2023.
  • Fourth quarter exploration program totalled 4,024 metres in 16 core drill holes and 23,160 metres in 103 reverse circulation holes.
  • Three satellite prospects east of the Gemfield deposit (Jupiter, Callisto, Kendall) were drill tested, with Jupiter and Callisto indicating a transition from deeper sulfide to shallow oxide mineralization in the up-dip projection.

Gemfield deposit and its immediate satellite target areas are geologically characterized by gently-dipping, intermediate and felsic volcanic units unconformably overlain by unconsolidated pebble to cobble conglomerate and down-dropped by post-mineral normal faults. Mineralization is typically hosted in stratabound Sandstorm rhyolite, although lower grade mineralization can be found in several of the felsic units, and is associated with a large, widespread blanket of quartz - alunite alteration dominated by pyrite in a high sulfidation environment. The Jupiter and Callisto prospects represent deeper sulfide mineralization transitioning to shallow oxide mineralization in the up-dip projection of the host stratigraphy. Exploration activities focused on defining the extent of the oxide mineralization, and additional exploration activities are planned at both Jupiter and Callisto in 2024. Significant results received during the year include:

Hole #GEM-23-R122 : 80.0m @ 6.94g/t Au from 65m
Hole #GEM23D26 : 173.5m @ 1.82 g/t Au from 441m
Hole #GEM23R170 : 190.0m @ 1.20 g/t Au from 370m
Hole #GEM23R170 : 170.0m @ 0.47 g/t Au from 595m
Hole #GEM-23-R112 : 80.0m@ 1.41 g/t Au from 315m
Hole #GEM23R175 : 85.0m@ 1.18 g/t Au from 435m
Hole #GEM23R157 : 170.0m @ 0.47 g/t Au from 605m
Hole #GEM-23-R125 : 50.0m @ 1.55 g/t Au from 250m
Hole #GEM-23-R102 : 40.0m @ 1.79 g/t Au from 290m
Hole #GEM-23-R116 : 200.0m @ 0.35 g/t Au from 125m

Oakley Project (“Oakley”)

In 2023, Centerra earned into a 70% interest in Oakley and subsequently acquired the remaining 30% interest from Excellon Resources Inc., bringing the Company’s total interest in the project to 100%. Exploration activities in the second half of 2023 continued to define a near-surface, structurally controlled, low sulfidation epithermal gold occurrence at the Blue Hill prospect. Additional epithermal style gold prospects were identified in the fourth quarter in other parts of the project area. These targets will be drill tested during 2024. Significant results received during the year include:

Hole #BHC-23-10 : 46.5m @ 0.55 g/t Au from 27.5m
Hole #BHC-23-10 : 64.0m @ 0.40 g/t Au from 78.0m
Hole #BHC-23-11 : 32.9m @ 0.34 g/t Au from 45.2m
Hole #BHC-23-11 : 25.0m @ 0.94 g/t Au from 102.0m
Hole #BHC-23-17 : 39.8m @ 0.28 g/t Au from 35.5m
Hole #BHC-23-20 : 45.5m @ 0.43 g/t Au from 79.0m
Hole #BHC-23-21 : 32.1m @ 0.32 g/t Au from 61.5m
Hole #BHC-23-21 : 38.5m @ 0.49 g/t Au from 159.0m
Hole #BHC-23-27 : 34.1m @ 0.34 g/t Au from 91.5m
Hole #BHC-23-27 : 47.0m @ 0.39 g/t Au from 129.4m

Öksüt Mine (“Öksüt”)

In the fourth quarter of 2023, five core drill holes were completed at Öksüt, aimed to test for a potential deep porphyry target beneath the Keltepe and Güneytepe pits. The exploration for deep porphyry deposits was initiated based on historical drill holes confirming potassic alteration related to porphyry intrusive on the Öksüt license. In 2024, a detailed alteration analysis is expected to be carried out using 2023 and deep historical holes drilled in and around Öksüt.

A full listing of the drill results has been filed on SEDAR+ at www.sedarplus.ca, EDGAR at www.sec.gov/edgar, and is available on the Company’s website at www.centerragold.com.

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”, “continue”, “estimate”, “expect”, “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); 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.
