Eldorado Gold Announces New Lamaque Technical Study

Highlighting Significant Increased Economic Upside

VANCOUVER, BC – Eldorado Gold Corporation (“Eldorado”, the “Company” or “We”) is

pleased to announce the results of a new Technical Study (the “Study”) on its wholly-owned

Lamaque Project, located in Val d’Or, Quebec. The Lamaque Project is comprised of three

separate but contiguous properties: Lamaque South (containing the Upper Triangle zones, Lower

Triangle zones, and the deposits of Parallel and Ormaque), Sigma-Lamaque and Aumaque (see

Figures 1 and 2). The Upper Triangle zones within Lamaque South are currently being mined with

access by surface ramp. The Study includes an update to the current operation, updated

economics on the Upper Triangle zones (zones C1 through C5), as well as preliminary economic

assessments on the inferred resources in the Lower Triangle zones (zones C6 through C10) and

the Ormaque deposit.

Key Highlights

• Base case economics using a gold price assumption of $1,500 per ounce:

o Upper Triangle Reserves NPV5%1 of $459 million

o Lower Triangle Inferred Resource NPV5% of $162 million and IRR2,3 of 33%

o Ormaque Inferred Resources NPV5% of $197 million and IRR 39%2,4

• Upside economics using spot gold price assumption of $1,900 per ounce:

o Upper Triangle Reserves NPV5% of $673 million

o Lower Triangle Inferred Resource NPV5% of $295 million and IRR of 48%

o Ormaque Inferred Resources NPV5% of $285 million and IRR 45%

• Key growth opportunities: High-grade inferred resources (Lower Triangle zones and

Ormaque deposit) provide potential for significant production increases and opportunities for

resource expansion. Based on successful conversion of inferred resources at Lower Triangle

and Ormaque, mining would commence in these areas in 2026. With multiple concurrent

centers of production, this represents a de-risked approach to extending the production profile

at Lamaque.

• Increased gold production to over 190,000 ounces per year based on the Upper Triangle

reserves; and sustaining over 180,000 ounces per year with production from Lower Triangle

Inferred and Ormaque inferred resources.

• Extended mine life with ~5.5 years of production from Upper Triangle reserves, and potential

for an additional ~8.5 years of mine life from Lower Triangle and Ormaque inferred resources.

• Well-positioned in the prolific Abitibi Greenstone Belt: In 2021, Eldorado expanded its

land position by over 500% with the acquisition of QMX Gold (referred to as the Bourlamaque

property), which is in close proximity to the Lamaque Project.

• Readily equipped: Robust surface infrastructure is already in place at the Triangle mine. To

support current operations and continue mining the Upper Triangle Reserves, additional

infrastructure is required on the Sigma tailings, and the mine dewatering systems.

• Permitting advancing and in compliance: The Lamaque Project is fully permitted under

Federal and Provincial regulations. The project is in compliance regarding environmental

quality and is regularly assessed by Provincial authorities in accordance with the

Environmental Quality Act (“EQA”) of Quebec. Discussions with Provincial Ministries about

making changes to the existing permits have commenced with Provincial Ministries and are

expected to be a normal course.

• Strong collaboration and support from the Val-d’Or communities and a transparent and

predictable regulatory environment makes Quebec a world-class mining jurisdiction.

IRR for Lower Triangle is calculated on the differential after-tax cash flow between the Lower

Triangle + Upper Triangle (B) and the standalone Upper Triangle case (A). 4 NPV and IRR for

Ormaque is calculated on the differential after-tax cash flow between the Ormaque + Lower

Triangle + Upper Triangle (C) and (B).

“The Lamaque Project has been an outstanding acquisition for Eldorado Gold,” said George

Burns, Eldorado’s President and CEO. “We acquired the asset for approximately $360 million in

2017, published a PFS in 2018, and reached commercial production 12-months later. Since then,

we have demonstrated a track record of success by replacing reserves year -over-year and

exceeding peak production levels beyond the 2018 Pre-Feasibility Study. Additionally, we have

more than doubled the inferred resource base since the acquisition. The results of the Technical

Study showcase the growing value of Lamaque and the significant upside potential from the

Lower Triangle zones and Ormaque deposit.”

“With the Triangle-Sigma decline project now complete, we are focused on an exploration drift

and resource conversion at Ormaque,” adds Burns. “Our 2022 exploration strategy is also focused

on resource expansion at Ormaque and in the Upper and Lower Triangle zones and testing new

targets within our expanded license area to support continued growth at Lamaque. Furthermore,

our strategic positioning in the Abitibi region gives us additional exposure to the potential upside

in the resource-rich area. We have a safe, successful track record of project execution and project

delivery, which is a testament to our team. We are fortunate to have a dedicated and experienced

workforce whose commitment to project delivery has been unwavering. Our strategic position in

the region and our strong, collaborative local relationships will allow us to continue to drive

sustainable, long-term benefits for the community in Val -d’Or, and continue to deliver value for

our shareholders.”

1 The Inferred Resources Cases are PEAs. As the PEAs supporting the Ormaque Inferred Resources and

the Lower Triangle Inferred Resources consider the potential economic viability of developing the separate

satellite deposit that comprises the Ormaque Inferred Resources and the separate zones that comprise the

Lower Triangle Infer red Resources in conjunction with the main zones of the Upper Triangle Reserves

development project, these PEAs will not impact the results of the economic/financial assessment of the

Upper Triangle Reserves.

2 The project’s cashflow remains positive in each year, as such there is no calculated internal rate of return

or payback period. Capital expenditures are part of ongoing operational development and are funded by

ongoing gold sales and there are no external funding requirements.

3 These measures are non-IFRS measures. See the section ‘Non-IFRS Measures’ at the end of this press

release and in Eldorado’s December 31, 2020 MD&A for explanations and discussion of these non -IFRS

measures.

The PEAs of Inferred Resources from the Lower Triangle zones and the Ormaque deposit are distinct

from and do not affect the feasibility-level update to the current operations on the Mineral Reserves in

the Upper Triangle zones and Parallel deposit.

Review of Operations

Eldorado owns the Lamaque Project in Quebec, Canada through its wholly-owned subsidiary,

Eldorado Gold Québec. The deposits at Lamaque are currently , and will continue to be , mined by

underground methods. In 2022, over 815,000 tonnes of ore at an average gold grade of 6.75 grams

per tonne are expected to be mined and process ed from the Upper Triangle zones. 2022 cash

operating costs per ounce 1 of $620 to $670 reflect increased mining and processing costs due to

higher throughput and cost inflation.

measures have been incorporated by reference and additional detail can be found at the end of this press

release and in the section ‘Non-IFRS Measures’ of Eldorado’s December 31, 2020 MD&A.

Property Description

The Lamaque Project is situated near the city of Val -d’Or in the province of Québec, Canada,

approximately 550 km northwest of Montréal. Val-d’Or has been a highly active mining area for a

century, with significant mineral deposits found throughout the region. Gold has been produced from

the historic Sigma and Lamaque mines starting in the early 1930’s. More recently, Eldorado acquired

the Lamaque Project through the purchase of Integra Gold Corp in 2017. Eldorado achieved

commercial production on March 31, 2019, from ore mined at the Upper Triangle zones and processed

at the refurbished Sigma mill.

Since the acquisition of Integra Gold Corp. by Eldorado in 2017, significant exploration activities have

been conducted at both Upper Triangle and Lower Triangle zones as well as other deposits and targets

including Plug #4, Parallel, Aumaque, South Gabbro, Lamaque Deep, Vein #6, P5 Gap, Sigma East

Extension and Sector Nord. In January 2020, Eldorado announced the discovery of the Ormaque

deposit. Eldorado continues to explore the Lamaque property and adjacent Bourlamaque property

extensively.

Review of Economic Analysis1

The Upper Triangle Reserves NPV5% of $459 million, based on $1,500 per ounce gold, has increased

significantly over the 2018 Pre-Feasibility Study (“PFS”). The Upper Triangle Reserves feasibility-level

economic analysis includes Reserves from the Parallel deposit.

Separately, the PEA for the Lower Triangle Inferred Resource, based on $ 1,500 per ounce gold ,

supports an additional NPV5% of $162 million.

Separately, the PEA for the Ormaque Inferred Resource, based on $1,500 per ounce gold, indicates

an additional NPV5% of $197 million.

The economic models were subjected to sensitivity analyses to determine the effects of changing

metal prices, capital, and operating expenditures on financial returns. This analysis showed that the

project economics are robust and are most sensitive to metal prices.

release and in Eldorado’s December 31, 2020 MD&A for explanations and discussion of these non -IFRS

measures.

Optimization and Future Opportunity

As part of an overall growth strategy in the Abitibi area, Eldorado continues to evaluate exploration

and development opportunities for high-grade ore that could be mined and trucked to the Sigma mill

as well as bulk mining opportunities that would entail upgrading the Sigma mill to its permitted capacity

of 5,000 tonnes per day.

Another area for opportunity highlighted in the Technical Study was the use of alternate materials

handling technologies for the Lower Triangle zones. Materials handling trade-off studies at a PEA level

indicate a potential for reducing costs, reducing equipment and ventilation requirements, while at the

same time reducing greenhouse gas emissions. Further studies will be carried out to increase the level

7

of confidence in the costs and benefits of technologies evaluated, which include vertical conveyors,

conventional conveying, or the use of battery electric vehicle trucks.

Geology and Mineralization

There are three deposits: i) Triangle, consisting of zones C1 through C5 in Upper Triangle, and C6

through C10 in Lower Triangle, ii) Parallel and iii) Ormaque . Gold mineralization in the Triangle ,

Parallel and Ormaque deposits occurs primarily within quartz-tourmaline-carbonate-pyrite shear and

extension veins. At Triangle, most of the deposit is contained within a series of shear veins (C1-C10)

emplaced along steeply south-dipping reverse shear zones. The ore zones are localized where the

shear zones cut across the subvertical Triangle Plug, but extend into the adjacent mafic lapilli-blocks

tuffs as well.

The Parallel and Ormaque deposits are located two kilometers northwest of the Triangle mine portal,

adjacent to the Triangle-Sigma decline. Mineralized veins in both are hosted within fine- to medium-

grained C-porphyry diorite. Ormaque is dominated by gently south-dipping extension veins and minor

breccia zones, localized adjacent to sub-vertical shear zones. At Parallel, mineralized zones consist

of gently-dipping extension veins in the upper part of the deposit and more steeply -dipping shear-

hosted veins at deeper levels.

Infrastructure

Through its existing infrastructure, the Lamaque Project is readily equipped to support all

planned operations. The Triangle mine site infrastructure includes offices, dry storage, truck shop,

warehouse, ventilation facilities, waste rock stockpile, slurry plant, cement silo, and fuel station. The

Sigma Mill site includes a processing plant, covered ore storage, crushing facilit y and a warehouse.

Support infrastructure also includes administration, construction, and exploration offices, as well as a

core yard.

The site has its own water management and collection ponds. The existing power line connecting the

Sigma Mill to the Triangle mine is designed to accommodate current as well as foreseeable future

operations.

Environment and Permitting

The Triangle mine at the Lamaque Project is an operating mine and is fully permitted under Federal

and Provincial regulations. The asset is in compliance regarding environmental quality and is regularly

assessed by Provincial authorities regarding EQA of Québec. Mineralized material in Lower Triangle

is fully permitted under existing certificates of authorizations (“CoA”).

There is an existing CoA for mining in the Ormaque deposit, but this will require an amendment to

allow for mining below a depth of 453 meters. There are no indications that the project will be

unsuccessful in obtaining a permit amendment.

Reclamation costs for the Lamaque Project were evaluated at $10 million based on recent

assessments and a full review of the closure plan is scheduled in 2023.

Mineral Resources Estimate

The table below provides the Mineral Resource Estimate for the Lamaque Project as of September

30, 2021. The Mineral Resources were classified using logic consistent with the CIM Definition

Standards for Mineral Resources and Mineral Reserves refe rred to in National Instrument 43 -101.

Notes on Mineral Resources

Mineral Resources and Mineral Reserves are as of September 30, 2021, unless otherwise stated.

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 exec ution of the next step where constraining

surfaces or volumes were created to control resource reporting. Underground Resources were

constrained by 3D volumes whose design was guided by the reporting cut -off grade or value,

contiguous areas of mineralizat ion and mineability. Only material internal to these volumes were

eligible for reporting.

2. Cut-off Grades

Lamaque: 3.0 g/t Au; Ormaque: 3.5 g/t Au

Triangle Deposit

The Mineral Resource estimates for the Upper Triangle zones and the Lower Triangle zones of the

Triangle deposit used data from both surface and underground diamond drillholes. The resource

estimates were made from 3D block models created by utilizing comm ercial geological modelling

and mine planning software. The block model cell size is 5 meters east by 5 meters north by 5 meters

high. The mineral resources are reported within the constraining mineralized domain volumes that

were created to control resource reporting and at a 3.0 grams per tonne (“g/t”) gold cut-off grade.

Parallel Deposit

The Mineral Resource estimate for the Parallel deposit used data from surface diamond drillholes. The

resource estimates were made from 3D block models created by utiliz ing commercial geological
