TORONTO, May 14, 2024 (GLOBE NEWSWIRE) -- Centerra Gold Inc. (“Centerra” or the “Company”) (TSX: CG and NYSE: CGAU) today reported its first quarter 2024 operating and financial results.

President and CEO, Paul Tomory, commented, “Centerra had a strong quarter of operating performance with production and costs outperforming our expectations. At Mount Milligan, we continued to advance a site-wide optimization program, implementing tangible initiatives in several areas, including concentrate management, mine operations and mine-to-mill optimization. We are also focused on a preliminary economic assessment to evaluate the substantial mineral resources at the Mount Milligan mine to unlock value beyond its current 2035 mine life. At Öksüt, we remain on track with elevated production in the first half of the year, in line with our guidance.

“In the first quarter of 2024, our cash and cash equivalents increased to $647.6 million, despite making the $24.5 million payment related to the additional agreement with Royal Gold. We have been active on share buybacks in late February and March, delivering on our disciplined capital allocation strategy. Looking ahead, in the second quarter we expect to make tax and annual royalty payments in Türkiye, totalling approximately $105 million, which will impact our cash balance. We continue to believe that Centerra is well positioned to achieve its 2024 guidance, as we are delivering on our value maximizing strategy for the Company’s portfolio of assets,” concluded Mr. Tomory.

2024 Outlook

The Company’s 2024 outlook previously disclosed in the MD&A for the year ended December 31, 2023, filed on SEDAR+ at www.sedarplus.ca and EDGAR at www.sec.gov/edgar, is unchanged except for the following revisions: the Kemess Project’s reclamation costs have been revised down from the range of $24 to $30 million to the range of $19 to $25 million and the expected Öksüt Mine taxes have been increased from the range of $46 to $52 million to the range of $54 to $60 million due to higher gold prices. The Company notes that except for the changes highlighted above the rest of the outlook remains unchanged. The Company’s full year 2024 outlook, as adjusted, and comparative actual results for the three months ended March 31, 2024 are set out in the following table:

1. Consolidated Centerra figures.
2. The Mount Milligan Mine is subject to the Mount Milligan Streaming Agreement. Using an assumed market gold price of $2,000 per ounce and a blended copper price of $3.75 per pound for 2024, Mount Milligan Mine’s average realized gold and copper price for the remaining three quarters of 2024 would be $1,419 per ounce and $2.96 per pound, respectively, compared to average realized prices of $1,552 per ounce and $3.12 per pound in the three-month period ended March 31, 2024, when factoring in the Mount Milligan Streaming Agreement and concentrate refining and treatment costs. The blended copper price of $3.75 per pound factors in copper hedges in place as of March 31, 2024.
3. In 2024, gold and copper production at the Mount Milligan Mine is projected with recoveries estimated at 64% and 78%, respectively.
4. Unit costs include a credit for forecasted copper sales treated as by-product for all-in sustaining costs^NG and all-in costs^NG. Production for copper and gold reflects estimated metallurgical losses resulting from handling of the concentrate and metal deductions levied by smelters.
5. Units noted as ($/oz) relate to gold ounces and ($/lb) relate to copper pounds.

1. Outlook range for the Thompson Creek Mine relates to the first half of 2024 only.
2. Includes care and maintenance costs as well as reclamation costs included in the reclamation provision as at March 31, 2024.
   
   

Mount Milligan
Mount Milligan produced 48,317 ounces of gold and 14.3 million pounds of copper in the first quarter of 2024. Mining activities were carried out in phases 6, 7, and 9 of the open pit. A total of 12.3 million tonnes were mined in the first quarter of 2024. Process plant throughput for the first quarter of 2024 was 5.2 million tonnes, averaging 56,728 tonnes per day. Mount Milligan is on track for its 2024 gold production guidance of 180,000 to 200,000 ounces and copper production guidance of 55 to 65 million pounds. Both gold and copper production are expected to be evenly weighted throughout the year, however, gold and copper sales in the second half of 2024 are expected to contribute approximately 55% of the annual sales.

Gold production costs in the first quarter 2024 were $954 per ounce, in line with $946 per ounce last quarter. AISC on a by-product basis^NG was $688 per ounce, 27% lower than last quarter, due to lower sustaining capital expenditures and higher by-product credits. The Company expects gold production costs and AISC on a by-product basis^NG to be higher in the second quarter of 2024 as a result of a lower percentage of annual sales in the first half of 2024 (as noted above), along with higher expected sustaining capital expenditures. Mount Milligan is on track for its full year 2024 gold production costs guidance and AISC on a by-product basis^NG guidance.

In the first quarter 2024, sustaining capital expenditures at Mount Milligan were $4.1 million, focused on the tailings storage facility, projects related to water sourcing and access, equipment overhauls, and equipment purchases. The Company maintains the 2024 sustaining capital guidance at Mount Milligan and expects the sustaining capital spending to increase throughout the year.

In the first quarter of 2024, Centerra made progress on its site-wide optimization program at Mount Milligan, initially launched in the fourth quarter 2023 and focused on a holistic assessment of occupational health and safety, as well as improvements in mine and plant operations. This program covers all aspects of the operation to maximize the potential of the orebody, setting up Mount Milligan for long-term success to 2035 and beyond. Notable achievements in the first quarter of 2024 were observed in key areas, including:

• Occupational health and safety: An improved safety record, including an increase in proactive safety interactions, fewer incidents and a much lower severity index compared to the same period last year. There has been a significant increase of focus and measurement of the leading indicators such as our visible felt leadership program, root cause incident investigation and mitigation of fatal risks (MFR). These initiatives collectively have contributed to cultivating a safer and more informed workplace, fostering the well-being and productivity of all personnel.
• Mine: Increase in the mining fleet mechanical availability, utilization and overall productivity of the load-haul cycle. These strategies have contributed to higher tonnes mined compared to the same period last year, while simultaneously lowering the unit operating costs.
• Plant: Increased mill throughput per operating day due to factors such as consistent ore supply, renewed operating strategy of the flotation circuit and equipment modifications. Additionally, as part of the optimization efforts, the site has started to test a number of initiatives that aim to increase the overall copper and gold recoveries. This includes real-time adjustments to the flotation circuit for improved stabilization with optimal grind sizing and throughput, producing a higher volume of gold-copper concentrate with lower copper grades and ore blending initiatives to improve the processing of elevated pyrite bearing high-grade gold, low-grade copper ore.
  

On February 14, 2024, Centerra announced that the Company has entered into an additional agreement with Royal Gold relating to Mount Milligan, which has resulted in a life of mine extension to 2035 and established favourable parameters for potential future mine life extensions. Centerra has initiated a preliminary economic assessment (“PEA”) to evaluate the substantial mineral resources at the Mount Milligan mine with a goal to unlock additional value beyond its current 2035 mine life. The PEA is expected to be completed in first half of 2025.

Öksüt

Öksüt produced 63,024 ounces of gold in the first quarter of 2024. Mining activities were focused on phase 5 and phase 6 of the Keltepe pit and in phase 2 of the Güneytepe pit. In the first quarter 2024, a total of 3.7 million tonnes were mined and 1.0 million tonnes were stacked at an average grade of 1.44 g/t. The Company is on track to achieve its production 2024 guidance with approximately 60% of the annual production weighted to the first half of the year.

Gold production costs and AISC on a by-product basis^NG for the first quarter 2024 at Öksüt were $587 per ounce and $823 per ounce, respectively. These costs per ounce were higher compared to last quarter primarily due to increased mining and hauling costs and higher weighted average costs per ounce in the remaining inventory, as well as decreased gold production and sales. Öksüt is on track to achieve its gold production costs guidance and AISC on a by-product basis^NG guidance for 2024.

In the first quarter 2024, sustaining capital expenditures at Öksüt were $11.3 million, focused on capitalized stripping and water treatment plant construction.

In 2024, Öksüt’s current income tax paid is expected to be approximately $95 to $105 million, with approximately $75 million to be paid in the second quarter of 2024, assuming no change in the exchange rate between the Turkish lira and US dollar. Additionally, the annual Turkish government royalty payment will be made in the second quarter 2024. This is expected to be approximately $30 million. Together, these cash payments will require a cash outflow in the second quarter 2024 of approximately $105 million.

Molybdenum Business Unit

In the first quarter 2024, the Molybdenum Business Unit sold 2.9 million pounds of molybdenum, generating revenue of $63.4 million with an average realized price of $20.47 per pound. As part of Centerra’s previously disclosed 2024 guidance, the Langeloth Metallurgical Facility (“Langeloth”) is expected to complete an acid plant maintenance shutdown in the second quarter 2024. A portion of Langeloth’s full year sustaining capital expenditure guidance is related to this planned outage. Molybdenum sales are not expected to be impacted by the acid plant maintenance shutdown as Langeloth has sufficient inventory levels to maintain a steady level of sales. As part of Centerra’s strategy to maximize the value for each asset in its portfolio, the Company has recently completed a commercial optimization plan at Langeloth, geared at increasing profitability and evaluating its future potential. Details of the commercial optimization plan and the value potential at Langeloth will be announced in conjunction with the Thompson Creek Mine feasibility study in late summer of 2024.

In the first quarter of 2024, the Thompson Creek Mine progressed with early works in the main open pit area that are expected to continue through 2024. The costs of these activities are expected to be expensed until a limited notice to proceed is authorized by the Board of Directors, a matter to be considered following completion of the feasibility study.

Non-GAAP and Other Financial Measures

This document contains “specified financial measures” 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’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 financial measures, non-GAAP ratios and supplementary financial measures used in this document:

• All-in sustaining costs on a by-product basisper 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 condensed consolidated statements of (loss) 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 first quarter ended March 31, 2024, 423 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 ‘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.
• All-in costs on a by-product basisper 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 other 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.
• Adjusted net earnings (loss) is a non-GAAP financial measure calculated by adjusting net (loss) earnings as recorded in the condensed consolidated statements of (loss) 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 (loss) 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.
• 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.
• Free cash flow (deficit) from mine operations is a non-GAAP financial measure calculated as cash provided by mine operations less property, plant and equipment additions. A reconciliation of free cash flow from mine operations to the nearest IFRS measures is set out below. Management uses this measure to monitor the degree of self-funding of each of its operating mines and facilities.

Certain unit costs, including all-in sustaining costs on a by-product basis (including and excluding revenue-based taxes) per ounce, are non-GAAP ratios which include as a component certain non-GAAP financial measures including all-in sustaining costs on a by-product basis which can be reconciled as follows:

Adjusted net earnings (loss) is a non-GAAP financial measure and can be reconciled as follows:

Free cash flow (deficit) is a non-GAAP financial measure and can be reconciled as follows:

Sustaining capital expenditures and non-sustaining capital expenditures are non-GAAP measures and can be reconciled as follows:
