Eldorado Gold Releases Updated Mineral Reserve and Mineral Resource Statement

To provide further clarity, on a go-forward basis, the Company is referring to specific assets within the Eldorado Gold Quebec portfolio as the Lamaque Complex. The Lamaque Complex includes the Triangle Mine (Upper and Lower), the Ormaque Deposit, the Parallel Deposit, the Plug #4 Deposit, and the Sigma Mill. This is consistent with how assets are described in the current technical report titled "Technical Report for the Lamaque Project, Québec, Canada'' with an effective date of December 31, 2021.

Mineral Reserves Update

The Company's Proven and Probable Gold Mineral Reserves ("2P Reserves"), totalled 11.7 million ounces as of September 30, 2023⁽ⁱ⁾, a decrease of approximately 5% from the previous MRMR statement as of September 30, 2022. Excluding depletion, the 2P Reserves year over year remained relatively flat. The complete table of Mineral Resources and Mineral Reserves can be found at the end of this release.
(i) See "Mineral Reserve Notes" following the detailed tables at the end of this news release.

Excluding depletion, the change in Proven and Probable Reserves is attributable to a reduction in Reserves at Perama Hill to reflect a revised, smaller pit shell, in accordance with current permitting limitations. Total Resources for Perama Hill are unchanged.

Additions to Reserves were made in the Bati zone at Efemcukuru and at Olympias.

• Kisladag: Reserves decreased with depletion
• Efemcukuru: Reserves replaced depletion through inclusion of Bati
• Lamaque Complex: Reserves decreased due to depletion outpacing conversion as it became more challenging to drill Lower Triangle zones at sufficient density. Resource conversion is expected to progress more quickly as the ramp advances and new drilling platforms are established to test the deeper zones more efficiently.
• Olympias: Reserves increased due to additional drilling and higher metal prices

The following table summarizes the year-over-year changes to the Company's Gold Mineral Reserves:

Mineral Resources Update

Eldorado's Measured and Indicated Gold Mineral Resources totalled 19.0 million ounces, as of September 30, 2023.⁽ⁱ⁾ This is a 1% decrease from the previous MRMR statement on September 30, 2022, attributable to the conversion of Inferred to Measured and Indicated resources primarily at Efemcukuru, Olympias, and the Lamaque Complex, offset by depletion at Efemcukuru, Kisladag, the Lamaque Complex and Olympias. Eldorado's Inferred Gold Mineral Resources totalled 7.6 million ounces as of September 30, 2023, a 2% decrease from the previous MRMR statement on September 30, 2022.
⁽ⁱ⁾ _{See "Mineral Resource Notes" following the detailed tables at the end of this news release. Mineral Reserves are included in the Mineral Resources.}

• Efemcukuru: The decrease in Inferred Resources is attributable to the upgrade to Measured and Indicated Resources at Kokarpinar South.
  
• Kisladag: The decrease in Measured and Indicated Resources is primarily from depletion.
• Lamaque Complex: The increase in Measured and Indicated at Triangle represented conversion from Inferred Resources, however depletion outpaced conversion.
  • Ormaque: Initial Indicated Resources were converted from Inferred at Ormaque through resource conversion drilling. Additionally, new Inferred Resources were added beyond the amount converted to Indicated. Plans are being advanced to declare initial Reserves in late 2024 following completion of a pre-feasibility study, continued conversion drilling, and extraction of a bulk sample.

Olympias: Inferred Resources were included based on drilling in the bottom section of the East zone.

ADVISORIES AND DETAILED NOTES ON MINERAL RESERVES AND RESOURCES

General

Mineral Resources and Mineral Reserves are as of September 30, 2023

The Mineral Resources and Mineral Reserves 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 while independent certified assay labs are used.

Mineral Reserves are included in the Mineral Resources.

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

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 a great uncertainty as to their economic and legal feasibility. It cannot be assumed that all or any part of an "indicated mineral resource" or "inferred mineral resource" will ever be upgraded to a higher category.

Additional information on the mineral properties mentioned in this news release that are considered to be material mineral properties to the Company are contained in Eldorado's annual information form for the year ended December 31, 2022 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:

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 Resources and Mineral Reserves 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 the Triangle Mine within the Lamaque Complex) were determined using a long-term gold price of $1,400/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.

1. Long-Term Metal Price Assumptions

• Gold price: $1,400/oz
• Silver price: $19.00/oz
• Copper price: $2.75/lb
• Lead price: $2,000/t
• Zinc price: $2,500/t

2. Cut-off Grades

Efemcukuru: $123.62/t NSR (long hole stoping), $126.60/t NSR (drift and fill); Kisladag: 0.17 g/t Au Recoverable; Lamaque (Triangle Mine): 5.06 g/t Au; Olympias: $217.63/t NSR; Perama Hill: 0.81 g/t Au; Skouries: $10.60/t NSR (open pit), $33.33/t NSR (underground).

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. 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.

1. Long-Term Metal Price Assumptions:

• Gold price: $1,800/oz
• Silver price: $24/oz
• Copper price: $3.25/lb
• Lead price: $2,200/t
• Zinc price: $2,800/t

2. 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.

3. Cut-off Grades

Certej: 0.60 g/t Au; Efemcukuru: 2.5 g/t Au; Kisladag: 0.25 g/t Au (in-situ); Lamaque (Triangle Mine): 3.0 g/t Au; Ormaque: 3.5 g/t Au; Olympias: $125/t NSR; Perama Hill and Perama South: 0.50 g/t Au; Piavitsa: 4.0 g/t Au; Sapes: 2.5 g/t Au (underground), 1.0 g/t Au (open pit); Skouries: 0.30 g/t Au Equivalent grade (open pit), 0.70 g/t Au Equivalent grade (underground) (=Au g/t + 1.25*Cu%); Stratoni: $200/t NSR.
