TORONTO, Aug. 01, 2024 (GLOBE NEWSWIRE) -- Centerra Gold Inc. (“Centerra” or the “Company”) (TSX: CG and NYSE: CGAU) today reported its second quarter 2024 operating and financial results.

President and CEO, Paul Tomory, commented, “Centerra delivered another quarter of solid operating performance and maintained consistent cash flow from operations before changes in working capital and income taxes paid, with year-to-date production and costs in line with our guidance. We ended the second quarter with cash and cash equivalents of $592 million after making routine statutory tax and royalty payments in Türkiye totalling $105 million. We remained active on share buybacks and declared a quarterly dividend, delivering on our disciplined approach of returning capital to shareholders.

“Looking ahead, later this summer we expect to announce our integrated strategy for the Molybdenum Business Unit, including results of a feasibility study on the restart of the Thompson Creek mine and the details of an optimized commercial model at Langeloth. Additionally, we expect to publish an initial resource estimate at Goldfield by the end of 2024 and a preliminary economic assessment in the first half of 2025 illustrating future potential at Mount Milligan. Our production, cost and capital expenditure guidance for 2024 is unchanged. We continue to deliver on our value maximizing strategy, focused on realizing the full potential of each of Centerra’s assets,” concluded Mr. Tomory.

2024 Outlook

There has been no change to the Company’s 2024 guidance metrics except the expected Öksüt Mine current income taxes were increased from a range of $54 to $60 million to a range of $64 to $70 million reflecting higher gold prices expected for the year. The Company’s full year 2024 outlook, as adjusted, and comparative actual results for the six months ended June 30, 2024 are set out in the following table:

1. Consolidated Centerra figures.
2. The Mount Milligan Mine is subject to an arrangement with RGLD Gold AG and Royal Gold Inc. (together, “Royal Gold”) which entitles Royal Gold to purchase 35% and 18.75% of gold and copper produced, respectively, and requires Royal Gold to pay $435 per ounce of gold and 15% of the spot price per metric tonne of copper delivered (“Mount Milligan Mine Streaming Agreement”). Using an assumed market gold price of $2,200 per ounce and a blended copper price of $4.25 per pound for the second half of 2024, Mount Milligan Mine’s average realized gold and copper price for the remaining two quarters of 2024 would be $1,578 per ounce and $3.32 per pound, respectively, compared to average realized prices of $1,955 per ounce and $3.41 per pound in the six-month period ended June 30, 2024, when factoring in the Mount Milligan Streaming Agreement and concentrate refining and treatment costs. The blended copper price of $4.25 per pound factors in copper hedges in place as of June 30, 2024.
3. Gold and copper production for the second half of the year at the Mount Milligan Mine assumes estimated recoveries of 63% to 65% for gold and 76% to 78% for copper compared to actual recoveries for gold of 65.1% and for copper of 76.5% achieved in the first six months of 2024. The Company estimates full year recoveries of 64% for gold and 78% for copper.
4. Unit costs include a credit for forecasted copper sales treated as by-product for all-in sustaining costs^NG and all-in costs^NG. Production for copper and gold reflects estimated metallurgical losses resulting from handling of the concentrate and metal deductions levied by smelters.
5. Units noted as ($/oz) relate to gold ounces and ($/lb) relate to copper pounds.

Molybdenum Business Unit

1. Additions to PP&E calculations for calculating Free Cash Flow (Deficit) from Operations^NG include only cash expenditures for PP&E additions.
2. Relates to the original outlook range for the Thompson Creek Mine for the first six months of 2024 only. The difference between original guidance range and actual amount incurred for the six months ended June 30, 2024 is expected to be spent in the third quarter of 2024.
3. Project evaluation expenses are recognized as expense in the consolidated statements of earnings (loss).

Project Evaluation, Exploration, and Other Costs

The Company’s 2024 outlook for the Goldfield Project, Kemess Project, corporate administration, and other exploration projects and comparative actual results for the six months ended June 30, 2024 are set out in the following table:

1. Outlook range for the Thompson Creek Mine relates to the first six months of 2024 only.
2. Total exploration costs include capitalized exploration costs at the Mount Milligan Mine of $1.0 million for the six months ended June 30, 2024.
3. Kemess Project costs include care and maintenance costs as well as reclamation costs included in the reclamation provision as at June 30, 2024.

Mount Milligan

Mount Milligan produced 38,609 ounces of gold and 13.5 million pounds of copper in the second quarter of 2024. Mining activities were carried out in phases 5, 6, 7, and 9 of the open pit. A total of 12.3 million tonnes were mined in the second quarter of 2024. Process plant throughput for the second quarter of 2024 was 5.3 million tonnes, averaging 58,520 tonnes per day. Gold sales were down 30% and copper sales were down 25% compared to last quarter. As previously disclosed, the lower sales volumes were anticipated due to the timing of shipments. Both gold and copper sales are expected to increase in the second half of 2024, contributing approximately 60% of annual sales. 2024 guidance metrics at Mount Milligan remain unchanged.

Gold production costs in the second quarter 2024 were $1,102 per ounce. AISC on a by-product basis^NG was $1,234 per ounce, higher than last quarter due to lower sales (as noted above) and higher sustaining capital expenditures.

In the second quarter 2024, sustaining capital expenditures at Mount Milligan were $17.4 million, focused on the tailings storage facility, equipment overhauls, projects related to water sourcing and access, and in-pit capital exploration.

Centerra continued to execute on its site-wide optimization program at Mount Milligan, initially launched in the fourth quarter 2023. The program is 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. While the optimization program is still ongoing, year-to-date the Company has started to see productivity improvements in the load-haul cycle at the mine, as well as the unit processing costs related to recycling grinding media and maintenance efficiencies. In the first six months of 2024, milling costs were $5.60 per tonne processed, 12% lower than the first six months of last year. Due to the longer-term nature of the mining optimization initiatives, the Company expects to see improvements in mining costs per tonne in 2025.

In February 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. Work is progressing on 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 the first half of 2025.

Öksüt

Öksüt produced 51,219 ounces of gold in the second quarter of 2024. Production was lower than last quarter due to processing most of the gold inventory that had accumulated in the previous year and seasonally significant precipitation leading to a minor amount of dilution to the pregnant gold solution which negatively affected gold recoveries. Mining activities were focused on phase 5 and phase 6 of the Keltepe pit and in phase 2 of the Güneytepe pit. A total of 3.9 million tonnes were mined and 1.1 million tonnes were stacked at an average grade of 1.12 g/t. The 2024 production guidance at Öksüt is unchanged, with approximately 40% to 45% of the annual production weighted to the second half of the year.

Gold production costs and AISC on a by-product basis^NG for the second quarter 2024 at Öksüt were $729 per ounce and $943 per ounce, respectively. These costs were higher compared to last quarter primarily due to lower sales and higher royalty costs resulting from higher average realized gold prices. Öksüt’s gold production costs guidance and AISC on a by-product basis^NG guidance for 2024 is unchanged. However, AISC on a by-product basis^NG could exceed the guidance range if gold prices remain at current levels, due to resulting higher royalty rates.

In the second quarter 2024, sustaining capital expenditures at Öksüt were $8.8 million, focused on capitalized stripping, heap leach pad expansion and waste rock dump expansion.

In the second quarter of 2024, the Company made an annual royalty payment of $28.6 million and tax payments of $76.4 million to the Turkish government. However, cash flow from operations at Öksüt before statutory payments for tax and royalty remained consistent quarter-over-quarter.

Molybdenum Business Unit

In the second quarter 2024, the Molybdenum Business Unit sold 2.7 million pounds of molybdenum, generating revenue of $61.2 million with an average realized price of $22.10 per pound. As part of Centerra’s previously disclosed 2024 guidance, Langeloth underwent an acid plant maintenance shutdown in the second quarter 2024, which was completed on time and on budget. The site has returned to normal operations.

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 second quarter of 2024, Thompson Creek continued 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.

While the current Thompson Creek mine permit authorizations support early works and certain activities defined under the limited notice to proceed, Centerra is advancing discussions with an inter-agency task force to obtain permit modifications for the full scope of an optimized mine plan, which includes additional land for the pit highwall layback under the jurisdiction of the U.S. Forest Service. This permitting work is building on the historical permits already in place. In the second quarter of 2024, following environmental studies and regulatory reviews Centerra obtained authorizations for additional lands at Thompson Creek, which will enable a proposed pit highwall layback. Due to strong collaboration and proactive support from federal and Idaho state regulatory agencies, Centerra received authorizations, subject to a minor update to the reclamation plan. This is a key first step in the overall permitting process. Thompson Creek is also proactively progressing environmental studies which should support future permitting of a second mine plan modification for additional waste rock quantities which is not required for several years.

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 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 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 second quarter ended June 30, 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 basis per 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.
