Eldorado Gold Corp.: Releases Updated Mineral Reserve and Mineral Resource Statement

The Company's total MRMR is adjusted for the planned divestment of its non-core Romanian asset (Certej), which is consistent with the Company's strategy of focusing on core jurisdictions in its portfolio.

Mineral Reserves Update

Net of divestitures, the Company's Proven and Probable gold Reserves ("2P Reserves"), totalled 12.3 million ounces as of September 30, 2022⁽¹⁾, a decrease of approximately 4% from the previous MRMR statement as of September 30, 2021. 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.
() See "Mineral Reserve Notes" below.

Net of divestitures, and excluding depletion, the small change in Proven and Probable Reserves is attributable to conversion of Resources to Reserves in the Kokarpinar zone at Efemcukuru and infill drilling in the Upper Triangle zone at Lamaque. These gains were mostly offset by adjustments for cut-off value, metal prices and mine plan optimization at Olympias.

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

Mineral Resources Update

Eldorado's Measured and Indicated ("M+I") Resources totalled 19.2 million ounces, net of divestitures⁽¹⁾, as of September 30, 2022. This is a 2% decrease from the previous MRMR statement on September 30, 2021, attributable to decreases at Kisladag, Lamaque and Olympias. Eldorado's Inferred Resources totalled 7.7 million ounces as of September 30, 2022, a 3% increase from the previous MRMR statement on September 30, 2021, net of divestitures.
(1) The Company elected to allow the Bolcana exploration license to expire in 2021, and as such the applicable Mineral Resources have been removed from the Company's Mineral Resources statement.

• Efemcukuru: The decrease in Inferred Resources is attributable to the upgrade to M+I Resources at Bati and Kokarpinar, through resource conversion drilling, which demonstrates increasing geological confidence in the ore bodies, and removing isolated areas of M+I Resources that are not expected to enter the future mine plan.
  
• Lamaque: The Inferred Resource increased substantially due to geological model updates. The M+I decrease is attributable to depletion, partially offset by upgrades of Inferred Resources.
• Ormaque: The Inferred Resource increased to reflect the new Technical Study released in February 2022. As previously announced in the October 2022 exploration update, the resource conversion drilling program at Ormaque commenced in June 2022 and will continue through 2023, targeting the upper two-thirds of the deposit. Results from this resource conversion drilling program, up to mid-2023, are expected to be reflected in the Company's 2023 MRMR statement.

Notes on Mineral Resources and Reserves

1. Mineral Resources and Mineral Reserves are as of September 30, 2022
2. 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").
3. Mineral Reserves are included in the Mineral Resources.
4. 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.

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. All Mineral Reserves are determined using a long-term gold price ($1,300/oz). 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: $1,300/oz
• Silver price: $17.00/oz
• Copper price: $2.75/lb
• Lead price: $2,000/t
• Zinc price: $2,400/t

2. Cut-off Grades

Certej: 0.90 g/t Au Equivalent grade (=Au(g/t)+Ag(g/t)*0.0121); Efemcukuru: $104.00/t NSR (long hole stoping), $108.00/t NSR (drift and fill); Kisladag: 0.18 g/t Au Recoverable; Lamaque: 4.69 g/t Au; Olympias: $195.00/t NSR; Perama Hill: 0.73 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. 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: $2,600/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 (Bolcana), and underground Resources constrained by a reporting shape.

3. Cut-off Grades

Bolcana: 0.30 g/t Au Equivalent grade (open pit), 0.65 g/t Au Equivalent grade (underground) (=Au g/t + 1.27*Cu%); Certej: 0.60 g/t Au; Efemcukuru: 2.5 g/t Au; Kisladag: 0.25 g/t Au; Lamaque: 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.
