TORONTO, Aug. 06, 2025 (GLOBE NEWSWIRE) -- Centerra Gold Inc. (鈥淐enterra鈥� or the 鈥淐ompany鈥�) (TSX: CG and NYSE: CGAU) today reported its second quarter 2025 operating and financial results.

President and CEO, Paul Tomory, commented, 鈥淚n the second quarter, both Mount Milligan and 脰办蝉眉迟 contributed to a strong $98 million in cash flow from operations before changes in working capital and taxes paid, driven by high commodity prices. At Mount Milligan, we are updating our 2025 gold production and cost guidance ranges as a result of mining in lower grade zones and we are updating our 2025 cost guidance ranges at 脰办蝉眉迟 due to higher royalty costs driven by elevated gold prices and an updated royalty structure that was approved by the Turkish government in July 2025. We maintained a robust financial position, which has enabled Centerra to increase share buybacks to $27 million in the second quarter, up 80% compared to last quarter. In the first half of 2025, in line with our disciplined capital allocation strategy, we have repurchased $42 million of shares, with up to $75 million approved for the full year, which reinforces our confidence in the long-term value of our growing business.鈥�

Paul Tomory continued, 鈥淲e are pleased to be advancing with development and construction at the Goldfield project. Over the last several months, Centerra has undertaken additional technical work and project optimizations that have significantly enhanced Goldfield鈥檚 value proposition and have de-risked the project. Favourable gold prices combined with these recent developments have improved the Project鈥檚 economics, enabling us to move forward with execution. We believe Goldfield is well positioned to deliver strong returns, including an after-tax net present value (5%) (鈥淣PV_5%鈥�) of $245 million and an after-tax internal rate of return (鈥淚RR鈥�) of 30%, using a long-term gold price of $2,500 per ounce and including the impact of gold hedges. The project is expected to be funded from Centerra鈥檚 existing liquidity and is located in a top tier mining jurisdiction, with an approximate 7-year mine life, average annual production of 100,000 ounces in peak production years at an all-in sustaining cost^NG of $1,392 per ounce, and a competitive initial capital cost of $252 million. First production from Goldfield is expected by the end of 2028, which would grow Centerra鈥檚 near-term gold production profile, generate robust cash flow and deliver significant value to shareholders. We believe Goldfield to be ideally positioned in our project development pipeline as we continue to advance development of the longer-life Mount Milligan and Kemess gold-copper assets in British Columbia.鈥�

Second Quarter 2025 Highlights

Operations

• Production: In the second quarter 2025, consolidated gold production was 63,311 ounces, including 35,058 ounces from the Mount Milligan Mine (鈥淢ount Milligan鈥�) and 28,253 ounces from the 脰办蝉眉迟 Mine (鈥溍柊觳趺汲兮��). Copper production in the quarter was 12.4 million pounds.
• Sales: Second quarter 2025 gold sales were 61,335 ounces at an average realized gold price^NG of $2,793 per ounce and copper sales were 12.1 million pounds at an average realized copper price^NG of $3.62 per pound. The average realized gold and copper prices include the impact of the Mount Milligan streaming agreement with RGLD Gold AG and Royal Gold, Inc. (collectively 鈥淩oyal Gold鈥�).
• Costs: Second quarter 2025 consolidated gold production costs were $1,308 per ounce and all-in sustaining costs (鈥淎ISC鈥�) on a by-product basis^NG were $1,652 per ounce.
• Capital expenditures^NG: Second quarter 2025 additions to property, plant, and equipment (鈥淧P&E鈥�) and capital expenditures^NG were $55.6 million and $53.9 million, respectively. Sustaining capital expenditures^NG in the second quarter 2025 were $25.8 million and included construction at the tailings storage facility (鈥淭SF鈥�) and capitalized exploration at Mount Milligan, as well as capitalized stripping and expansion of the heap leach pad at 脰办蝉眉迟. Non-sustaining capital expenditures^NG in the second quarter were $28.1 million related mainly to the restart of operations at the Thompson Creek Mine (鈥淭hompson Creek鈥�).

Financial

• Net earnings: Second quarter 2025 net earnings were $68.6 million, or $0.33 per share, and adjusted net earnings^NG were $52.7 million or $0.26 per share. Key adjustments to net earnings include $15.0 million of unrealized gain on the re-measurement of the sale of the Greenstone Partnership in 2021, $12.1 million of unrealized loss on the financial assets related to the additional agreement with Royal Gold Inc. (鈥淩oyal Gold鈥�), and $11.0 million of deferred income tax adjustments arising from the impact of foreign exchange rate movement on deferred income taxes at Mount Milligan, partially offset by a drawdown on the deferred tax asset related to Mount Milligan. For additional adjustments refer to the 鈥淣on-GAAP and Other Financial Measures鈥� disclosure at the end of this news release.
• Cash provided by operating activities and free cash flow^NG: In the second quarter 2025, cash provided by operating activities before working capital and income taxes paid was $98.4 million, up 22% from last quarter. Cash provided by operating activities was $25.3 million and free cash flow deficit^NG was $25.6 million, impacted mainly by statutory tax and royalty payments at 脰办蝉眉迟. This includes $57.2 million of cash provided by mine operations and $42.8 million of free cash flow^NG at Mount Milligan, offset by $17.6 million of cash used in mine operations and $28.2 million of free cash flow deficit^NG at 脰办蝉眉迟, and capital expenditures^NG at Thompson Creek.
• Cash and cash equivalents: Total liquidity of $922.3 million as at June听30, 2025, comprising a cash balance of $522.3 million and $400.0 million under a corporate credit facility.
• Returning capital to shareholders: Quarterly dividend declared of C$0.07 per common share for a total of $10.5 million in the second quarter, and $20.6 million year-to-date. Under Centerra鈥檚 normal course issuer bid (鈥淣CIB鈥�) program, the Company repurchased 3,889,507 common shares (鈥淪hares鈥�) in the second quarter 2025, for total consideration of $27.0 million, up 80% compared to last quarter. The Company鈥檚 board of directors has approved the repurchase of up to $75 million of Centerra鈥檚 Shares through the NCIB in 2025, of which, the Company has completed $42.0 million year-to-date. Centerra believes that the NCIB will continue to provide the Company with a flexible tool to deploy cash pursuant to its capital allocation strategy, while preserving the financial flexibility to support investment in future growth.

Strategic Growth Initiatives

• Advancing the Goldfield project: Centerra has completed a technical study of its Goldfield project (鈥淕oldfield鈥� or 鈥渢he Project鈥�), which confirms attractive economics for the Project, including an after-tax NPV_5% of $245 million and an after-tax IRR of 30%, using a long-term gold price of $2,500 per ounce. This includes the impact of gold hedges, with a gold price floor of $3,200 per ounce, on a portion of production in 2029 and 2030 to lock in strong margins, safeguard economics in the early years of the Project, and expedite the capital payback period. The initial capital investment at Goldfield is $252 million, including approximately $40 million in pre-production stripping and other costs, and the Project is expected to benefit from a short timeline to first production by the end of 2028 and low execution risk given its relatively simple process flow sheet. The Project is located in a historic mining district of Nevada, offering a stable regulatory environment, skilled workforce, and strong support for resource development. Over the last several months, Centerra has undertaken additional technical work and optimizations that have significantly enhanced Goldfield鈥檚 value proposition and de-risked the project. Favourable gold prices combined with these developments have improved the Project鈥檚 economics, enabling Centerra to move forward with execution. The Project is expected to provide an increase in gold production, which will help offset natural declines at 脰办蝉眉迟, and ensure continuity as Centerra advances its next phase of long-life, gold-copper, cornerstone organic growth projects in British Columbia at Mount Milligan and Kemess. For additional details on Goldfield, refer to the news release published on August 6, 2025 titled 鈥�Centerra Gold Announces Attractive Economics on the Goldfield Project; Proceeding with Project Development and Construction Activities鈥�.
• Two project studies supporting Centerra鈥檚 long-life gold-copper organic growth strategy in British Columbia are progressing positively toward completion in the second half of 2025: At Mount Milligan, work on a Pre-Feasibility Study (鈥淧FS鈥�) to evaluate the substantial mineral resources aimed at unlocking additional value beyond its current mine life of 2036 is on track to be completed in the third quarter of 2025. At the Kemess project (鈥淜emess鈥�), the Company continues to successfully advance work on a Preliminary Economic Assessment (鈥淧EA鈥�), based on an open pit and longhole open stoping underground mining concept, which is expected to be completed by the end of 2025. Kemess has significant infrastructure already in place that will require some refurbishment. Complementing this existing infrastructure, it is anticipated that new crushing, conveying, and mine infrastructure will be required for the operations. Centerra expects the existing infrastructure to lower the execution risk for the project when compared with a typical greenfield project of this scale. These studies represent significant milestones in advancing the Company鈥檚 gold growth development pipeline and are focused on unlocking additional value from its assets in British Columbia, a top tier mining jurisdiction.

2025 Guidance 鈥� Global Exploration and Evaluation Projects

Mount Milligan

Mount Milligan produced 35,058 ounces of gold and 12.4 million pounds of copper in the second quarter of 2025. During the second quarter of 2025, a total of 12.4 million tonnes was mined from phases 5, 6, 7 and 10 of the open pit. Process plant throughput for the second quarter of 2025 was 5.3 million tonnes, averaging 58,302 tonnes per day. In the first half of 2025, mining operations have encountered zones with more challenging mineralization, resulting in lower than anticipated gold grades from these areas of the pit. While gold grades remain above the average grade of the reserve, the Company believes that the variability is primarily attributed to certain zones being drilled with wider spacing. Centerra has commenced an infill and grade control drilling program in the second quarter of 2025. This initiative is expected to improve geological and mine plan confidence and will be integrated into the upcoming Mount Milligan PFS, contributing to a mine plan with greater visibility on grades moving forward. The Company is updating 2025 gold production guidance at Mount Milligan to 145,000 to 165,000 ounces, from 165,000 to 185,000 ounces previously, to recalibrate for the adjustment in grades while ensuring strategic priorities are maintained. The Company is reaffirming its 2025 copper production guidance range of 50 to 60 million pounds of copper. Gold sales were 33,727 ounces and copper sales were 12.1 million pounds in the second quarter. Both gold and copper production and sales are expected to be weighted towards the second half of the year.

Gold production costs in the second quarter 2025 were $1,356 per ounce. AISC on a by-product basis^NG was $1,286 per ounce, 10% higher than last quarter due to increased sustaining capital expenditures and lower ounces sold during the quarter. Centerra has increased its guidance ranges for 2025 gold production costs and AISC on a by-product basis^NG at Mount Milligan to reflect updated production guidance. Gold production costs for the year are expected to be between $1,350 and $1,450 per ounce, revised from between $1,075 and $1,175 per ounce previously. AISC on a by-product basis^NG for the year are expected to be between $1,350 and $1,450 per ounce, revised from between $1,100 and $1,200 per ounce previously.

In the second quarter 2025, sustaining capital expenditures^NG at Mount Milligan were $14.7 million, focused on the tailings storage facility dam construction and capitalized exploration. While full year PP&E and total capital expenditures^NG at Mount Milligan remains unchanged at $75 to $90 million, the allocation between sustaining and non-sustaining capital has been revised. Sustaining capital expenditures^NG are now expected to be $60 to 70 million, down from $65 to $75 million previously, with a corresponding increase in non-sustaining capital expenditures^NG to $15 to $20 million, up from $10 to $15 million previously, reflecting project priorities and timing adjustments.

In the second quarter of 2025, Mount Milligan generated $57.2 million of cash flow from mine operations and free cash flow^NG of $42.8 million.

At Mount Milligan, work on the PFS to evaluate the substantial mineral resources to unlock additional value beyond its current mine life is on track to be completed in the third quarter of 2025. The Company is optimistic that it can extend the current mine life beyond 2036, which is based on the available space in the existing TSF. Centerra is progressing with the engineering solution for additional tailings capacity. It is also expected that the PFS will incorporate an increase of annual mill throughput in the range of 10% through ball mill motor upgrades at a modest overall capital expenditure, which may also provide the benefit of improved overall metal recovery.

脰办蝉眉迟

脰办蝉眉迟 produced 28,253 ounces of gold in the second quarter of 2025. Production in the quarter was better than planned due to higher grades resulting from mine sequencing. The Company expects to access higher grade areas of the mine in the second half of 2025. During the quarter, mining activities were focused on phase 5 and phase 6 of the Keltepe pit and in phase 2 of the G眉neytepe pit. A total of 4.6 million tonnes of ore and waste were mined in the quarter and 1.2 million tonnes were stacked at an average grade of 0.90 g/t. Centerra reaffirms 脰办蝉眉迟鈥檚 2025 production guidance of 105,000 to 125,000 ounces, which is expected to be weighted towards the second half of the year.

At 脰办蝉眉迟, gold production costs and AISC on a by-product basis^NG for the second quarter 2025 were $1,250 per ounce and $1,755 per ounce, respectively. These costs were higher compared to last quarter primarily due to a higher royalty expense per ounce due to elevated gold prices. 脰办蝉眉迟鈥檚 2025 gold production costs and AISC on a by-product basis^NG guidance ranges have been revised to reflect both higher royalty costs due to higher gold prices, and an updated royalty structure that was approved by the Turkish parliament in July 2025. Full year gold production costs at 脰办蝉眉迟 are now expected to be $1,200 to $1,300 per ounce, up from $1,100 to $1,200 per ounce previously. 2025 AISC on a by-product basis^NG are now expected to be $1,675 to $1,775 per ounce, up from $1,475 to $1,575 per ounce previously.

In the second quarter 2025, sustaining capital expenditures at 脰办蝉眉迟 were $10.6 million, focused on capitalized stripping, heap leach pad expansion and the water treatment plant.

In the second quarter 2025, the Company made an annual royalty payment of $37.9 million and tax payments of $46.2 million to the Turkish government. As a result, 脰办蝉眉迟 used $17.6 million of cash in mine operations and had a negative free cash flow^NG of $28.2 million in the quarter. Nonetheless, cash flow from operations at 脰办蝉眉迟 before statutory payments for tax and royalty increased by over 32% in this quarter compared to last quarter.

Molybdenum Business Unit (鈥淢BU鈥�)

In the second quarter of 2025, as planned during the restart of Thompson Creek, the MBU used $1.1 million of cash in operations and recorded free cash flow deficit^NG of $26.9 million, reflecting capital spending that positions the business for positive future cash flows.

Thompson Creek Mine

The restart of Thompson Creek is advancing, with approximately 20% of the total capital investment complete. In the second quarter of 2025, non-sustaining capital expenditures^NG were $26.5 million. Since the restart decision, non-sustaining capital expenditures^NG have totaled $81.9 million. The 2025 guidance for additions to PP&E, all of which are non-sustaining capital^NG is unchanged at $130 to $145 million. The project remains in line with the total initial capital expenditures^NG estimate of $397 million as outlined in the feasibility study and is on track for first production in the second half of 2027

Langeloth

In the second quarter of 2025, the Langeloth Metallurgical Facility (鈥淟angeloth鈥�) roasted and sold 3.2 million pounds and 3.1 million pounds of molybdenum, respectively. In the quarter, Langeloth delivered a positive adjusted EBITDA^NG of $0.2 million and generated $0.8 million in cash flow from operations.

Non-GAAP and Other Financial Measures

This document contains 鈥渟pecified financial measures鈥� within the meaning of NI 52-112, specifically the non-GAAP financial measures, non-GAAP ratios and supplementary financial measures described below. Management believes that the use of these 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鈥檚 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 (鈥淲GC鈥�) guidelines. Accordingly, these specified financial measures should not be considered in isolation, or as a substitute for, analysis of the Company鈥檚 recognized measures presented in accordance with IFRS.

Definitions

The following is a description of the non-GAAP financial measures, non-GAAP ratios and supplementary financial measures used in this document:

• 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, the cash component of 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. 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 the three months ended June听30, 2025, 658 pounds of copper were 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.
• 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 鈥榥ew operations鈥� and costs related to 鈥榤ajor projects at existing operations鈥� 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.
• Adjusted net earnings is a non-GAAP financial measure calculated by adjusting net earnings as recorded in the consolidated statements of earnings for items not associated with ongoing operations. The Company believes that this generally accepted industry measure allows the evaluation of the results of income-generating capabilities and is useful in making comparisons between periods. This measure adjusts for the impact of items not associated with ongoing operations. A reconciliation of adjusted net earnings to the nearest IFRS measures is set out below. Management uses this measure to monitor and plan for the operating performance of the Company in conjunction with other data prepared in accordance with IFRS.
• Adjusted EBITDA is a non-GAAP financial measure calculated by adjusting net earnings as recorded in the consolidated statements of earnings by depreciation, amortization, interest, taxes and items not associated with ongoing operations. The Company believes that this generally accepted industry measure allows the evaluation of the results of income-generating capabilities and is useful in making comparisons between periods. A reconciliation of adjusted EBITDA to the nearest IFRS measures is set out below. Management uses this measure to monitor and plan for the operating performance of the Company in conjunction with other data prepared in accordance with IFRS.
• Free cash flow (deficit) is a non-GAAP financial measure calculated as cash provided by operating activities from continuing operations less property, plant and equipment additions. A reconciliation of free cash flow to the nearest IFRS measures is set out below. Management uses this measure to monitor the amount of cash available to reinvest in the Company and allocate for shareholder returns.
• Mining costs per tonne mined is a non-GAAP financial measure calculated by dividing the mining costs by the number of tonnes mined. Management uses these measures to monitor the cost management effectiveness of the mining process for each of its operating mines.
• Processing costs per tonne stacked is a non-GAAP financial measure calculated by dividing the processing costs by the number of tonnes milled or stacked. Management uses these measures to monitor the cost management effectiveness of the mine processing for each of its operating mines.
• Site G&A costs per tonne processed is a non-GAAP financial measure calculated by dividing the site G&A costs by the number of tonnes milled or stacked. Management uses these measures to monitor the cost management effectiveness of the site G&A process for each of its operating mines.
• On site costs per tonne processed is a non-GAAP financial measure calculated by dividing the operating expenses less changes in inventories, royalties and other costs by the number of tonnes milled or stacked. Management uses these measures to monitor the cost management effectiveness of the relevant production costs for each of its operating mines.
