Eldorado Gold Releases Updated Mineral Reserve and Mineral Resource Statement; 2024 Gold Mineral Reserves Increased to 11.9 Million Oz with M&I Gold Mineral Resources of 22.0 Million Oz; Inaugural Mineral Reserve Declared at Ormaque; Outline of 2025

VANCOUVER, British Columbia, Dec. 11, 2024 (GLOBE NEWSWIRE) -- Eldorado Gold Corporation (“Eldorado” or “the Company”) today releases its updated Mineral Reserve and Mineral Resource (“MRMR”) estimates as of September 30, 2024.

“Our updated Mineral Reserves estimate provides a solid foundation and underpins our production profile over the next decade and beyond,” said George Burns, President and CEO. “We were pleased to increase our Mineral Reserves by approximately 2% overall, driven by increases at the Lamaque Complex and Efemcukuru that extends Reserve mine life significantly and complements our already long mine life assets at Skouries, Kisladag and Olympias. The Lamaque Complex Mineral Reserve increased by 45%, driven primarily by the declaration of an Inaugural Mineral Reserve at Ormaque of 619 thousand ounces. This follows a solid track record of successfully replacing Mineral Reserves since acquiring the asset in 2017 and sets up the Lamaque Complex for the long-term with two underground mines with significant Inferred Mineral Resource conversion potential and exploration upside.”

“In addition, at Efemcukuru, we increased Mineral Reserves by 23% resulting in an extension to the mine life by an additional two years to an updated life of mine of eight years. Efemcukuru has been a reliable producer since 2011, and our team remains committed to exploring opportunities to extend mine life further. During 2025, our focus will continue to be on extending the mine life at our existing operations and testing near-mine exploration targets, while seeking a discovery from our highly prospective portfolio of early stage exploration targets in Canada and Turkiye.”

Mineral Reserves Update

The Company’s Proven and Probable gold Mineral Reserves totalled 11.9 million ounces as of September 30, 2024, an increase of approximately 2% from the previous MRMR statement from September 30, 2023. The complete MRMR table and notes can be found at the end of this release.

(1) The Company’s total MRMR excludes Mineral Reserves at its non-core Romanian asset (Certej). As disclosed in the Q3 2024 Managements Discussion & Analysis, the Certej project has been presented as a disposal group held for sale as at September 30, 2024 and as a discontinued operation for the three and nine months ended September 30, 2024. On October 7, 2024, the Company entered into a share purchase agreement to sell the Certej project. The closing of the disposition is subject to certain conditions.
(2) Depletion declared here are in-situ ounces. Depletion includes the 12-month period of October 1, 2023, through September 30, 2024.

Excluding depletion, the increase in Mineral Reserves is primarily attributable to additions at Kokarpinar South at Efemcukuru as well as an inaugural Mineral Reserve estimate for the Ormaque deposit within the Lamaque Complex.

• Lamaque Complex: Mineral Reserves increased 45% with the addition of Ormaque, partially offset by depletion at Triangle, resulting in an increase in life of mine to eight years.
  • Ormaque: Inaugural Mineral Reserve of 619 thousand ounces at Ormaque.
  • Triangle: Mineral Reserves decreased primarily as a result of depletion.
• Kisladag: Mineral Reserves decreased as a result of depletion, partially offset by positive design changes.
• Efemcukuru: Mineral Reserves increased with the addition of Kokarpinar South, increasing the life of mine by two years to an updated eight year life of mine.
• Olympias: Mineral Reserves decreased due to depletion and Resource modelling incorporating additional drilling.

The following table summarizes the period-over-period changes to the Company’s Mineral Reserves:

NOTE: Totals may not sum due to rounding.
(1) The Company reports its MRMR as of September 30, 2024.  As such, the change year over year is from October 1, 2023 to September 30, 2024.

Mineral Resources Update

Eldorado’s Measured and Indicated Mineral Resources (“M&I Mineral Resources”) totalled 22.0 million ounces gold, as of September 30, 2024. The Company successfully converted Inferred Mineral Resources to M&I Mineral Resources at Ormaque, within the Lamaque Complex, and at Efemcukuru. The total is offset by depletion at the other operating mines. This resulted in a 3% decrease from the previous MRMR statement from September 30^th, 2023. Eldorado’s Inferred Mineral Resources totalled 6.8 million ounces as of September 30, 2024, a 10% decrease from the previous MRMR statement. Detailed MRMR disclosure tables are included at the end of this news release.

• Lamaque Complex: The increase in total M&I Mineral Resources is primarily related to conversion from Inferred Mineral Resources at Ormaque, whilst partially offset by depletion at Triangle.
  • Ormaque: M&I Mineral Resources increased nearly 300% attributable to significant expansion and conversion of Inferred Mineral Resources. Inferred Mineral Resources decreased as a result of the above-mentioned conversion, partially offset by the addition of new Inferred Mineral Resources.
  • Triangle: M&I Mineral Resources decreased due to depletion and Inferred Mineral Resources decreased due to discontinuities in C7 vein continuity recognised during in-fill drilling, grade changes, and cut-off grade assumptions, coupled with conversion to M&I Mineral Resources.
• Kisladag: The decrease in M&I Mineral Resources is primarily from depletion. Inferred Mineral Resources remained relatively unchanged period-over-period.
• Efemcukuru: The decrease in M&I Mineral Resources is primarily from depletion, partially offset by the conversion to Mineral Reserves at Kokarpinar South. The slight decrease in Inferred Mineral Resources is attributable to conversion to M&I Mineral Resources.
• Olympias: Both M&I Mineral Resources and Inferred Mineral Resources decreased due to depletion, model estimation parameters updates, and the exclusion of un-minable material which were previously included, off-setting extensional discoveries. As part of the annual review of Mineral Resources with respect to reasonable prospects for eventual economic extraction (“RPEEE”), some un-mineable material was removed due to proximity to existing infrastructure, areas of poor geotechnical conditions and inaccessibility due to previous mining activities.  

The following table summarizes the period-over-period changes to the Company’s Mineral Resources:

NOTE: Totals may not sum due to rounding.
(1) Mineral Resources are inclusive of Mineral Reserves.
(2) The Company Reports on its MRMR as of September 30, 2024. As such, the change year over year is from October 1, 2023 to September 30, 2024.
(3) As disclosed in the Q3 2024 Managements Discussion & Analysis, the Certej project has been presented as a disposal group held for sale as at September 30, 2024 and as a discontinued operation for the three and nine months ended September 30, 2024. On October 7, 2024, the Company entered into a share purchase agreement to sell the Certej project. The closing of the disposition is subject to certain conditions.

ADVISORIES AND DETAILED NOTES ON MINERAL RESERVES AND RESOURCES

General

Mineral Reserves and Mineral Resources are as of September 30, 2024

The Mineral Reserves and Mineral Resources were classified using logic consistent with the CIM Definition Standards for Mineral Resources & Mineral Reserves (2014) incorporated, by reference, into National Instrument 43-101 – Standards of Disclosure for Mineral Projects (“NI 43-101”). Sample preparation, analytical techniques, laboratories used, and quality assurance and quality control protocols used during exploration drilling programs are done consistent with industry standards and independent certified assay labs are used.

Mineral Reserves are included in the Mineral Resources.

The Mineral Reserves and Mineral Resources are disclosed on a total project basis.

Measured and Indicated Mineral Resources which are not Mineral Reserves, do not have demonstrated economic viability. With respect to “Inferred Mineral Resources”, there is a great amount of uncertainty as to their existence and uncertainty as to their economic and legal feasibility. It cannot be assumed that all or any part of a “Measured Mineral Resource”, “Indicated Mineral Resource” or “Inferred Mineral Resource” will ever be upgraded to a higher category.

Additional information on the Kisladag, Efemcukuru, Olympias, Skouries and Lamaque mineral properties mentioned in this news release (all of which are considered to be material mineral properties to the Company) are contained in Eldorado’s annual information form for the year ended December 31, 2023 and the following technical reports for each of those properties, all of which are available under the Company's profile at www.sedarplus.com and www.sec.gov:

• Technical report entitled "Technical Report, Kisladag Gold Mine, Turkiye” with an effective date of January 17, 2020.
• Technical report entitled "Technical Report, Efemcukuru Gold Mine, Turkiye” with an effective date of December 31, 2023.
• Technical report entitled “Technical Report, Olympias Mine, Greece” with an effective date of December 31, 2023.
• Technical report entitled “Technical Report, Skouries Project, Greece” with an effective date of January 22, 2022.
• Technical report entitled “Technical Report, for the Lamaque Project, Quebec, Canada’” with an effective date of December 31, 2021.
• In addition, Eldorado will file a new technical report for the Lamaque mineral properties (which will include the inaugural reserves at Ormaque noted above) by the end of January 2025.

Cautionary Note to US Investors Concerning Estimates of Measured, Indicated and Inferred Resources
There are differences between the standards and terms used for reporting mineral reserves and resources in Canada, and in the United States pursuant to the United States Securities and Exchange Commission’s (the “SEC”). The terms Mineral Resource, Measured Mineral Resource, Indicated Mineral Resource and Inferred Mineral Resource are defined by the Canadian Institute of Mining, Metallurgy and Petroleum (CIM) and the CIM Definition Standards on Mineral Reserves and Mineral Resources adopted by the CIM Council, and must be disclosed according to Canadian securities regulations.

These standards differ from the requirements of the SEC applicable to domestic United States reporting companies. Accordingly, information contained in this news release with respect to mineral deposits may not be comparable to similar information made public by United States companies subject to the SEC’s reporting and disclosure requirements.

Mineral Reserve Notes

Eldorado reports Mineral Reserves in accordance with CIM Definition Standards. Mineral Reserves for the operating sites (Efemcukuru, Kisladag, Olympias, and within the Lamaque Complex – Ormaque and Triangle) were determined using a long-term gold price of $1,450/oz while Mineral Reserves for the Skouries and Perama Hill projects were determined based on a $1,300/oz gold price. A reserve test is undertaken every year to confirm future undiscounted cash flow from reserve mine plan is positive.

The following persons, all of whom are qualified persons under NI 43-101, have approved the disclosure related to the Mineral Reserves for the projects noted below contained within this release:

Mineral Resource Notes

Eldorado reports Mineral Resources in accordance with CIM Definition Standards. All Mineral Resources are assessed for reasonable prospects for eventual economic extraction (RPEEE). The Resource cut-off grades or values (e.g. gold equivalent) are determined using a long-term gold price ($1,800/oz) and modifying factors derived in the resource to reserve conversion process (or by comparison to similar projects for our resource-only properties). These values are then used to create constraining volumes that provide limits to the reported Resources. Resource grades are reported undiluted from within the constraining volumes that satisfy RPEEE.  At Efemcukuru, mineralized shapes based on RPEEE identified based on 2.5 g/t Au COG; within shapes material below incremental COG of 1.0 g/t have been excluded; grades are diluted by must-take material between 1.0 and 2.5 g/t Au. Due to the presence of narrow veins, any future potential conversion of Resources to Reserves at Ormaque will reflect expected lower grades to fully represent modifying factors associated with mining.

Open Pit Resources used pit shells created with the long-term gold price to constrain reportable model blocks. Underground Resources were constrained by volumes whose design was guided by a combination of the reporting cut-off grade or value, contiguous areas of mineralization and mineability. Eldorado’s Mineral Resources are inclusive of Reserves.

Mineral Resource Reporting and demonstration of Reasonable Prospects for Eventual Economic Extraction: 

The Mineral Resources used a long term look gold metal price of $1,800/oz for the determination of resource cut-off grades or values. This guided execution of the next step where constraining surfaces or volumes were created to control resource reporting. Open pit-only projects (Kisladag, Perama Hill, Perama South, and Certej) used pit shells created with the long-term gold price to constrain reportable model blocks.  Underground Resources were constrained by 3D volumes whose design was guided by the reporting cut-off grade or value, contiguous areas of mineralization and mineability. Only material internal to these volumes were eligible for reporting. Projects with both open pit and underground Resources have the open pit Resources constrained by either the permit (Skouries), and pit shell, or by an open pit/underground economic crossover surface, and underground Resources constrained by a reporting shape.

(1) Mineralized shapes based on RPEEE identified based on 2.5 g/t Au COG; within shapes material below incremental COG of 1.0 g/t have been excluded; grades are diluted by must-take material between 1.0 and 2.5 g/t Au.
