Eldorado Gold Releases Updated Mineral Reserve and Mineral Resource Statement

VANCOUVER, British Columbia, Dec. 15, 2021 (GLOBE NEWSWIRE) -- Eldorado Gold Corporation ("Eldorado" or "the Company") today releases its updated Mineral Reserve and Mineral Resource ("MRMR") estimates as of September 30, 2021.

Highlights

• Increase to Inferred Resources as a result of the maiden Inferred Resource at Ormaque announced in February 2021.
• Increase to Mineral Reserves and Measured and Indicated ("M+I") Resource at Efemcukuru is attributable to Resource upgrade associated with drilling, mostly at Kokarpinar and Kestanebeleni NW.

Mineral Reserves Update

The Company's Proven and Probable gold Reserves ("2P Reserves") totalled 17.0 million ounces as of September 30, 2021¹, a 4% decrease from the previous MRMR statement on September 30, 2020. Including the divestiture of Tocantinzinho, ("TZ"), which was divested from the portfolio October 27, 2021 the Company's 2P gold Reserves totalled 15.3 million ounces, a 14% decrease compared to September 30, 2020 (see Eldorado press release dated December 2, 2020). The complete table of Mineral Resources and Mineral Reserves can be found at the end of this release.

¹ See "Mineral Reserve Notes" below.
² Depletion declared here are processed ounces. Depletion includes Q4 2020 and Q1-Q3 2021.

Net of divestitures, the net change in Reserves is attributable to increases at Lamaque and Efemcukuru, and decreases at Kisladag, Skouries and Olympias.

• Lamaque: Both Mineral Reserve gold ounces and grade increased relative to September 2020 primarily due to conversion drilling in the C5 zone.
• Efemcukuru: Mineral Reserves increased mostly due to conversion of Resources to Reserves at Kestanebeleni NW and Kokarpinar.
• Kisladag: Mineral Reserves decreased due to depletion.
• Skouries: The decrease in Mineral Reserves, at the development project, is due to changes in cut-off values, mostly offset by reserve price increase.
• Olympias: The decrease in Mineral Reserves is due to mining method optimization and exclusion of remnant mining zones that will require further engineering studies to be included in the mine plan.

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

Mineral Resources Update

Exploration within our existing portfolio continues to deliver resource growth for the Company.

Eldorado reports Resources in accordance with CIM definition standards. The Resource cut-off grades or values (e.g. gold equivalent) are determined using a single 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 M+I Resources totalled 25.5 million ounces as of September 30, 2021, a 1% decrease from the previous MRMR statement on September 30, 2020 attributable to decreases at Kisladag, Skouries and Olympias, partially offset by increases at Lamaque and Efemcukuru. Including the TZ divestment, the M+I Resources totalled 23.5 million ounces, a decrease of 9% compared to September 30, 2020. Eldorado's Inferred Resources totaled 14.0 million ounces as of September 30, 2021, a 3% increase from the previous MRMR statement on September 30, 2020.

• Efemcukuru: The increase to M+I Resource is attributable to Resource upgrade associated with drilling, mostly at Kokarpinar and Kestanebeleni NW. The decrease in Inferred Resource at Efemcukuru is attributable to the combination of additional drilling and the corresponding upgrade to M&I Resources.
• Lamaque: All changes to the Resources are attributable to the results of additional drilling and upgrades of Inferred to M+I Resources. Ormaque was announced as a maiden Inferred Resource on February 22, 2021 (see Eldorado press release dated February 22, 2021).

The following table summarizes the year over year changes to Eldorado's gold Resources:

Mineral Resource Notes

?      ?1.   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) or by an OP/UG economic crossover surface (Bolcana), and underground Resources constrained by a reporting shape.

      2.   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.

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
Technical disclosure regarding the Company's properties included herein (the "Technical Disclosure") has been prepared in accordance with the requirements of the securities laws in effect in Canada, which differ from the requirements of United States securities laws. The terms "mineral reserve", "proven mineral reserve", "probable mineral reserve", "mineral resource", "measured mineral resource", "indicated mineral resource" and "inferred mineral resource" are Canadian mining terms as defined in accordance with NI 43-101. NI 43-101 is a rule developed by the Canadian Securities Administrators that establishes standards for all public disclosure an issuer makes of scientific and technical information concerning mineral projects. These standards differ from the requirements of the United States Securities and Exchange Commission (the "SEC") applicable to domestic United States reporting companies. Accordingly, information contained herein contain descriptions of our mineral deposits that may not be comparable to similar information made public by United States companies subject to the SEC's reporting and disclosure requirements.
