Eldorado Updates Lamaque Complex Technical Report;

Demonstrating Significant Value and Potential to Extend Mine Life to 17 Years

(All dollar figures are in US dollars, unless otherwise stated)

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

results of an updated Technical Report for the Lamaque Complex1 (“Lamaque Complex Technical Report”), including

an updated life-of-mine (“LOM”) plan based on Mineral Reserves from Triangle, Ormaque and Parallel (the “Reserve

Case”) and a Preliminary Economic Assessment (“PEA”) extended LOM plan primarily2 based on Inferred Mineral

Resources (“Inferred Resources”) from Triangle and Ormaque (the “PEA Case”).

The Reserve Case outlines an 8-year mine life producing 1.2 million ounces of gold, while the PEA Case shows the

potential to extend mine life incrementally by 9 years and incremental gold production of 1.5 million ounces. The

Lamaque Complex Technical Report has been filed on SEDAR+.

Lamaque Complex Technical Report Highlights

Table 1 summarizes key metrics for the Reserve Case and PEA Case from the Lamaque Complex Technical Report

which are based on the Mineral Reserve and Mineral Resource estimates that are shown in Appendix A.

Highlights of the Reserve Case

• Gold production of 1.2 million ounces over an 8-year mine life through 2032

• Average annual gold production above ~175,000 oz through 2028

• LOM All-In Sustaining Cost (“AISC”) of $1,176/oz Au3

• Solid economics with an:

o after-tax NPV(5%) of $555 million at a gold price of $2,000/oz

o after-tax NPV(5%) of $1.1 billion at a gold price of $2,600/oz

Highlights of the PEA Case

• Incremental g old production of 1.5 million ounces , showing the potential to extend mine life to 17 years

through 2041

• Maintains average annual gold production of ~185,000 oz through 2036, providing a long runway for the

Lamaque Complex and the Company’s overall business in Québec

• Maintains LOM AISC of $1,149/oz Au3

1 The Lamaque Complex includes the Triangle, Ormaque, Parallel and Plug No. 4 deposits, and the Sigma Mill (see Figure 2).

2 The PEA case includes a non-material amount of Measured and Indicated Mineral Resources (< 2%).

• Significant incremental economics highlight the long-term potential of the Lamaque Complex:

o after-tax NPV(5%) of $623 million at a gold price of $2,000/oz

▪ (for a total after-tax NPV(5%) of $1.2 billion when combined with the Reserve Case)

o after-tax NPV(5%) of $1.1 billion at a gold price of $2,600/oz Au

▪ (for a total after-tax NPV(5%) of $2.1 billion when combined with the Reserve Case)

o incremental IRR of the PEA case is 43.5% at a gold price of $2,000/oz Au

▪ 68.2% at a gold price of $2,600/oz Au

The PEA Case is preliminary in nature and includes Inferred Mineral Resources that are too speculative geologically

to have economic considerations applied to them that would enable them to be categorized as Mineral Reserves and

there is no certainty that the forecast production amounts will be realized. The basis for the PEA and the qualifications

and assumptions made by the qualified person s who undertook the PEA are set out in the advisories contained in

this news release . The results of the PEA had no i mpact on the results of any prefeasibility or feasibility study in

respect of the Lamaque Complex.

Maximizes installed capacity of plant and infrastructure with two mining centres. The installed capacity of the

Sigma Mill, along with extensive infrastructure both on surface and underground, can be maximized with the addition

of a paste plant and additional tailings capacity to bring the Ormaque deposit into production.

Strong collaboration and support from the Val -d’Or communities . We expect a transparent and predictable

regulatory environment, reflective of Québec being a Tier 1 mining jurisdiction.

Significant exploration potential to grow Mineral Resources in existing deposits. The Ormaque deposit remains

open at depth and laterally both in the upper and lower sections of the deposit. The Triangle deposit remains open at

depth and we continue to drill Plug No. 4 and other advanced targets on the property.

Well-positioned with a large, under-explored land package in the Val d’Or area. The Company continues to

assess exploration opportunities across the Lamaque Complex as well as its 100%-owned Bourlamaque property

(contiguous to the Lamaque Complex) and in the wider Abitibi region.

“This marks another major milestone for the Lamaque Complex ,” said George Burns, President and CEO. “After

acquiring this asset in 2017, we successfully brought the Triangle deposit into commercial production in 2019 , and it

has since produced nearly one million ounces of gold. With the development of the Ormaque deposit, we will be

adding a second underground mine to the Lamaque Complex, which provides operational flexibility and efficiency as

we leverage the existing plant and infrastructure.

“Ormaque is located just off the existing Triangle–Sigma decline and was discovered through surface drilling in 2019

(see Figure 2 and Figure 3). An Inferred Mineral Resource was declared in February 2021 and an exploration drift

was developed to allow underground conversion drilling of the upper sections of the deposit. A bulk sample of

Ormaque material was processed at the Sigma Mill in December and preliminary results are in-line with expectations

and support the current Ormaque Mineral Reserves and block model. The second phase of the bulk sample is

expected for the second half of 2025, followed by an expected ramp-up phase beginning in 2026. We expect to reach

full production in 2028.

“The Ormaque and Triangle deposits are located within the prolific Val -d’Or district of the Abitibi . This district hosts

the historic Lamaque and Sigma Mines , which collectively produced nearly 10 million ounces of gold. Based on the

existing resource base and favorable findings of the report, we maintain an optimistic view of the long -term potential

at the Lamaque Complex.

“Our skilled and dedicated workforce, strategic position in the Abitibi region and collaborative relationships with First

Nations and the local community, positions us to deliver sustainable, long-term benefits for the Val-d’Or region, while

continuing to create value for our shareholders.”

Significant Value Creation Since Acquisition

Eldorado acquired the Lamaque Complex in 2017 for total consideration of $430 million 4. Since acquisition, it has

generated over $3005 million of net cash flow and has been one of the Company’s most stable operations. Looking

forward, we expect the Lamaque Complex to generate significant value and remain a cornerstone asset for the

Company over the next decade and beyond . At a gold price of $2,000/oz , the Reserve Case generates an after-tax

NPV5% of $555 million, while the PEA Case generates an incremental after-tax NPV5% of $623 million. At a gold price

of $2, 600/oz, the Reserve Case generates an after-tax NPV 5% of $ 1.1 billion while the PEA Case generates an

incremental after-tax NPV5% of $1.1 billion (see Figure 4).

At the time of acquisition, the Lamaque Complex contained Measured and Indicated Mineral Resources (“M&I

Resources”) of 1. 4 million ounces of gold , Inferred Mineral Resources of 864,000 ounces of gold , and no Mineral

Reserves. Since acquisition, the Lamaque Complex has produced nearly one million ounces of gold , while growing

Mineral Reserves and Mineral Resources significantly (see Figure 5).

Lamaque Complex Planned Drilling and Regional Exploration

Exploration activities will continue at the Lamaque Complex, with a focus on resource conversion drilling at Lower

Triangle, Ormaque and Plug No. 4, as well as testing for extensions at Ormaque and earlier stage targets close to

Lamaque Complex infrastructure. Plans include:

• Resource conversion drilling at Lower Triangle, where a multi -year plan has been developed to leverage

access to drill platforms as underground infrastructure advances, while targeting deeper veins (C8 and below)

with longer drill holes with the objective of reducing geological risk ahead of development (see Figure 6).

• Resource conversion drilling at Ormaque , where drilling during 2025 will focus on extending the core of the

system at depth. Subsequent conversion drilling from 2026 onwards will be conditional upon ongoing

exploration drilling that is testing lateral and depth extensions, and will prioritize d omains of Inferred Mineral

Resources that deliver maximum value for the operation (see Figure 7).

• Resource conversion drilling at Plug No. 4 will continue during 2025 from an exploration drift located off the

Sigma-Triangle decline. Drilling will test the P30 to P50 veins, and conditional drilling is planned for 2026 and

2027 targeting shallower and deeper vein sets (see Figure 8).

• Surface drilling targeting additional Inferred Mineral Resources by testing lateral extensions of Ormaque,

which remains open in all directions at various levels of the deposit, is planned through 2025.

• In addition, exploration drilling from surface and underground will also test earlier stage targets proximal to

the Lamaque Complex infrastructure , including assessing the potential to extend known veins and testing

new targets. In parallel, the Exploration team will continue to generate and drill test targets within the Eldorado

land position in the wider district to assess future resource potential to feed the Sigma Mill.
