Reporting Mineral Reserves and Mineral 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 (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 for Mineral Resources & Mineral Reserves (the “CIM Definition Standards”) 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 AIF 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.

Except as otherwise noted, Simon Hille, FAusIMM, our Executive Vice President, Technical Services and Operations, is the “Qualified Person” under National Instrument 43-101 - Standards of Disclosure for Mineral Projects (“NI 43-101”) responsible for preparing or supervising the preparation of, or approving the scientific or technical information contained in this AIF for all our properties except Quebec. With respect to our properties in Quebec, Jessy Thelland, géo (OGQ No. 758) a member in good standing of the Ordre des Géologues du Québec, is the qualified person as defined in NI 43-101 responsible for, and has verified and approved, the scientific and technical disclosure contained in this AIF. Simon Hille and Jessy Thelland are employees of the Company.

In January 2021, Mr. Steven Reid was appointed as Chair of the Board.

In February 2021, the Company announced its wholly-owned subsidiary, Hellas Gold had entered into an amended investment agreement (the “Investment Agreement”) with the Hellenic Republic to govern the further development, construction and operation of the Kassandra Mines. The Investment Agreement amends the 2003 transfer agreement between Hellas Gold and the Hellenic Republic (the “Transfer Agreement”), and provides a modernised legal and financial framework to allow for the advancement of Eldorado’s investment in the Kassandra Mines. The Investment Agreement was subsequently ratified by the Hellenic Republic and the amendments to the Transfer Agreement became legally effective on March 23, 2021.

In February 2021, the Company announced an inaugural resource estimate for the recently-discovered Ormaque deposit within its Lamaque Complex in Québec. Inferred mineral resources for Ormaque were initially announced as 2.6 M tonnes at a grade of 9.5 grams per tonne gold, for 803,000 ounces of contained gold. Please see “About our Business” for further information and “Mineral Reserves and

Mineral Resources” for current resource estimates.

On March 30, 2021, the Company completed a flow-through private placement of 1,100,000 common shares at a price of C$16.00 per share for proceeds of C$17.6 M ($13.9 M). The proceeds were used to fund the Lamaque Complex decline project.

In April 2021, the Greek Ministry of Energy and Environment approved a modification to the Kassandra Mines Environmental Impact Assessment to allow for the use of dry stack tailings disposal at the Skouries Project. Dry stack technology involves filtering tailings to remove water prior to stacking and compacting the dry material in a designated tailings area.

In July 2021, the Company acquired 15,041,746 common shares of Probe Metals Inc. (“Probe”) at a price of $1.575 per common share, for an aggregate purchase price of C$24 M ($19 M).

•repay all amounts owing under its then outstanding term loan facility and revolving credit facility; and

•pay fees and expenses in connection with the foregoing.

•The remaining net proceeds were used for general corporate purposes.

In September 2021, the Company provided an update on its exploration programs including:

•At the Lamaque Complex, infill drilling at the Ormaque deposit confirmed grade continuity within ore lenses of the inaugural Inferred Resource and expanded several lenses laterally. Drillholes testing deeper levels identified several new mineralized zones.

•Significant drill results from the Bonnefond deposit in the then recently acquired Bourlamaque project area (formerly a QMX project area) indicated additional upside potential.

•At Efemçukuru, drilling at Kokarpinar focused on both conversion drilling within inferred resources and testing the previously undrilled Kokarpinar Northwest Splay.

In October 2021, the Company executed an amended and restated senior secured credit facility (the “Fourth ARCA”). The Fourth ARCA consists of a $250 M revolving senior secured credit facility (the

7

“Revolving Facility”) with an option to increase the available credit by $100 M through an accordion feature, as well as a letter of credit facility. The Fourth ARCA amended and replaced the May 2019 $450 M senior secured credit facility. For more information on the Notes and Fourth ARCA, please refer to pages 101 and 102.

On October 15, 2021, the Company announced that operations at Stratoni would be suspended at the end of 2021. The mine and plant were transferred to care and maintenance during 2022.

On October 27, 2021, the Company completed a sale of the Tocantinzinho Project, a non-core gold asset in Brazil. Eldorado received $20 M in cash consideration and 46,926,372 common shares of G Mining Ventures Corp (“GMIN”), representing 19.9% of the outstanding common shares of GMIN at the sale date. Deferred cash consideration of $60 M is payable on the first anniversary of commercial production of the Tocantinzinho Project, with an option to defer 50% of the consideration at a cost of $5 M. The Company currently holds approximately 17.7% of GMIN's outstanding shares.

In December 2021, the Company published the results of the Skouries Project Feasibility Study. Skouries is a high-grade copper-gold asset with a 20-year mine life and expected average annual production of 140,000 ounces of gold and 67 M pounds of copper (combined approximately 312,000 ounces gold equivalent). Highlights of the study (at an estimated gold price of $1,500 per ounce and an estimated copper price of $3.85 per pound) include an after-tax Internal rate of return (“IRR”) of 19% and an after-tax net present value (“NPV”) (5%) of $1.3 B.

In December 2021, the Company announced the successful completion of the Triangle-Sigma decline project at the Lamaque Complex. The completion of the growth project, connecting the ore transportation ramp between the Triangle mine and the Sigma processing plant, was on schedule and on budget.

In December 2021, the Company announced completion of the commissioning of the HPGR circuit at Kışladağ. The circuit, a key growth project, was expected to increase recovery by approximately 4% to 56%.

In December 2021, the Company updated its Reserve and Resource statement. The Company’s proven and probable gold reserves totalled 15.3 M ounces as of September 30, 2021, compared to 17.7 M ounces as of December 31, 2020, a decrease of 14%.

2022

In January 2022, the Company announced the appointment of Ms. Carissa Browning to the Board of Directors.

In February 2022, the Company published its inaugural Climate Change and Greenhouse Gas Emissions (“GHG”) Report, outlining a target of mitigating GHG emissions by 30% from 2020 levels, by 2030 on a ‘business as usual’ basis; equal to approximately 65,000 tonnes of carbon dioxide equivalent.

On February 24, 2022, the Company announced the results of a technical study updating the current operation at the Lamaque Complex, updated economics on the Upper Triangle zones (zones C1 through C5), as well as preliminary economic assessment on the inferred resources on the Lower Triangle zones (zones C6 through C10) and the Ormaque deposit. Highlights of the study included an updated resource estimate for the Ormaque deposit totaling 2,223,000 tonnes at a grade of 11.74 g/t gold of Inferred Resources, for 839,000 contained ounces of gold.

In September 2022, the Company entered into a mandate letter (the “Mandate Letter”) with Greek banks for a credit committee approved €680 M project finance facility for the development of the Skouries Project (the “Term Facility”). The Mandate Letter included a long-form term sheet, which contained customary terms and conditions. The Company’s Revolving Facility was also amended in September 2022 to permit the revolving credit facility to be used to provide a bank-issued letter of credit in favour of the Greek banks under the Mandate Letter. The bank-issued letter of credit was expected to be used to backstop the Company’s equity commitments to Hellas Gold in respect of the expected development and construction of the Skouries Project.

In December 2022, the Company announced that its wholly-owned subsidiary, Hellas Gold had entered into the Term Facility with National Bank of Greece S.A. and Piraeus Bank S.A. as lead arrangers. Consistent with the Company’s previous disclosure, the Term Facility will provide 80% of the expected future funding required to complete the Skouries Project. The Term Facility is non-recourse to Eldorado and the collateral securing the Term Facility covers the Skouries Project and the Hellas Gold operating assets. The remaining 20% of the Skouries Project funding is expected to be fully covered by Eldorado’s existing cash and future cash flow from operations. Until such further equity is fully invested, Eldorado’s

8

investment undertaking for the Skouries Project will be fully backstopped by a letter of credit from the Company’s Revolving Facility. Drawdown on the Term Facility was subject to customary closing conditions.

On December 15, 2022, the Company announced that its Board of Directors approved, conditional upon the initial drawdown of the Term Facility, the investment decision and full re-start of construction at Skouries.

The investment was effected by way of a private placement whereby the EBRD subscribed for 6,269,231 shares at a price of C$13.00 per share. (the “EBRD Private Placement”).

In addition, the Company announced that it had entered into an agreement with BMO Capital Markets and National Bank Financial, on behalf of a syndicate of underwriters (collectively, the “Underwriters”), pursuant to which the Underwriters agreed to purchase on a bought deal basis 10,400,000 million common shares of the Company at the same price as the EBRD Private Placement (that is, at C$13.00 per common share), for gross proceeds of C$135 million (the “Bought Deal Offering”).

On June 7, 2023 the Company announced the closing of the Bought Deal Offering.

During early-stage exploration, our teams visit prospective areas to conduct geological, geochemical and geophysical surveys and associated sampling, often partnering with other companies or prospectors to benefit from their local knowledge and experience. If results indicate a potential mineralized deposit, we drill exploration holes to determine whether economically viable concentrations of metals may exist. Successful projects will continue to advanced exploration, wherein drilling programs will define mineral resources whilst in parallel assessments are undertaken to determine potential for future development.

Evaluation and Development

During the evaluation and development stage, our engineering, technical services and metallurgy teams conduct studies to determine:

•the Mineral Resources contained in a project;

•the optimal mining methods and mineral recovery processes;

•the required infrastructure;

•the best placement and design of facilities, based on impact and migration assessments; and

•the required mine monitoring, closure and reclamation plans.

These studies provide information on the capital costs required for development and the longer-term economics of the project. We are then able to decide if a capital investment makes economic sense, and meets our required return rate in order to make capital allocation and construction decisions.

Construction

The assessment of the project’s environmental impact (generically referred to as an “EIA” herein, but also referred to as an “Environmental Impact Study” (“EIS”) or, if social factors are included, an Environmental and Social Impact Assessment ( “ESIA”)) and other relevant permits require approval by government authorities. Once we have received this, along with management’s investment committee approval as well as Board approval to proceed, our Capital Projects team can begin construction. Explicit requirements described in each EIA guide our activities and help us manage any social and environmental risks.

This construction phase requires the greatest input of capital and resources over a project’s life cycle, and throughout this phase we can add significant value to local economies through local job growth and procurement.

Mining and Processing

During production, our operations team and site personnel are responsible for mining and extracting ore from our underground mines (Efemçukuru, Olympias, Lamaque) and open pit mine (Kışladağ) as well as exploring for new reserves to expand production and mine life. The ore is processed on-site to produce concentrates or doré. Any leftover materials generated by our mining activities, which typically include topsoil, waste rock and tailings, are either placed on-site in engineered facilities for storage and treatment, or reused elsewhere on-site as part of construction activities, rehabilitation, or as underground backfill. Rigorous environmental monitoring – to test air, water and soil quality, noise, blast vibration and dust levels – enables us to comply with environmental regulations and our operating licenses and permits.

Reclamation and Closure

Restoring the land so it is compatible with the surrounding landscape is a priority for us and our communities in which we operate. How we conduct our rehabilitation in one jurisdiction impacts how we are welcomed in another. Therefore, prior to and throughout a mine’s operation, our operations teams develop and continuously enhance plans for the mine’s future closure in order to:

•protect public health and safety;

•prevent environmental damage;

•return the land to a natural condition, or an acceptable and productive alternative; and

•provide for long-term social and economic benefits

Sales of Mineral Products

We produce gold doré as well as gold, silver, lead and zinc contained in concentrates. Our in-country marketing teams are responsible for finding downstream smelters and refineries and establishing long-term working relationships and purchase agreements. These agreements outline the terms and conditions of payment for our products, and specify parameters and penalties for the quantity, quality and chemical composition of our doré and concentrate.

The gold doré produced at Kışladağ is refined to market delivery standards at gold refineries in Türkiye and sold at the spot price on the Precious Metal Market of the Borsa Istanbul. Gold doré is produced at Lamaque and is sold to local refineries in Ontario.

Contracts are also in place for the sale of concentrates from Greece and Türkiye. These include gold concentrates from Efemçukuru and Olympias as well as lead/silver and zinc concentrates from Olympias. These concentrates are sold under contract andare paid based on payable terms and metal prices for the contained metals.

How We Measure Our Costs

The Company has included certain non-IFRS financial measures and ratios in this document, as discussed below. The Company believes that these financial measures and ratios, in addition to conventional measures prepared in accordance with IFRS, provide investors with an ability to evaluate the underlying performance of the Company. The non-IFRS financial measures and ratios are intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS. These financial measures and ratios do not have any standardized meaning prescribed under IFRS, and therefore may not be comparable to other issuers. Certain additional disclosures for these non-IFRS financial measures and ratios have been incorporated by reference and can be found in the section ‘Non-IFRS and Other Financial Measures and Ratios’ in the December 31, 2023 MD&A filed on February 22, 2024 available on SEDAR+ (www.sedarplus.com).

Cash Operating Costs and Total Cash Costs are calculated using the standard developed by the Gold Institute, a worldwide association of suppliers of gold and gold products including leading North American gold producers. The Gold Institute stopped operating in 2002, but its standard is still widely used in North America to report cash costs of production. Adoption of the standard is voluntary, so you may not be able to compare the costs reported here to those reported by other companies.

Cash Operating Costs and Cash Operating Costs per Ounce Sold

Cash Operating Costs and Cash Operating Cost per ounce sold are non-IFRS financial measures and ratios. In the gold mining industry, these metrics are common performance measures but do not have any standardized meaning under IFRS. The Company calculates costs following the recommendations of the Gold Institute Production Cost Standard. Cash operating costs include direct operating costs (including mining, processing and administration), treatment, refining and transportation charges, but exclude royalty expenses, depreciation and amortization, share based payment expenses and reclamation costs. Revenue from sales of by-products including silver, lead and zinc reduce cash operating costs. Cash operating costs per ounce sold is calculated by dividing cash operating costs by gold ounces sold in the period. The Company discloses cash operating costs and cash operating cost per ounce sold as it believes these measures assist investors and analysts in evaluating the Company’s operating performance and ability to generate cash flow. The most directly comparable IFRS measure is production costs.

Total Cash Costs, Total Cash Costs per Ounce Sold

Total Cash Costs and Total Cash Costs per ounce sold are non-IFRS financial measures and ratios. Total cash costs is defined as the sum of cash operating costs (as defined above) and royalties. Total cash costs per ounce sold is calculated by dividing total cash costs by gold ounces sold in the period. The Company discloses total cash costs and total cash costs per ounce sold as it believes these measures assist investors and analysts in evaluating the Company’s operating performance and ability to generate cash flow. The most directly comparable IFRS measure is production costs.

All-in Sustaining Cost (AISC), AISC per Ounce Sold

AISC and AISC per ounce sold are non-IFRS financial measures and ratios. AISC is defined based on the definition set out by the World Gold Council, including the updated guidance note dated November 14, 2018. The Company defines AISC as the sum of total cash costs (as defined above), sustaining capital expenditure relating to current operations (including capitalized stripping and underground mine development), sustaining leases (cash basis), sustaining exploration and evaluation cost related to current operations (including sustaining capitalized evaluation costs), reclamation cost accretion and amortization related to current gold operations and corporate and allocated general and administrative expenses. Corporate and allocated general and administrative expenses include general and administrative expenses, share based payments and defined benefit pension plan expense. Corporate and allocated general and administrative expenses do not include non-cash depreciation. As this measure seeks to reflect the full cost of gold production from current operations, growth capital and reclamation cost accretion not related to operating gold mines are excluded. Certain other cash expenditures, including tax payments, financing charges (including capitalized interest), except for financing charges related to leasing arrangements, and costs related to business combinations, asset acquisitions and asset disposals are also excluded. AISC per ounce sold is calculated by dividing AISC by gold ounces sold in the period.

The Company discloses AISC and AISC per ounce sold as it believes these measures assist investors, analysts and other stakeholders with understanding the full cost of producing and selling gold and in evaluating the Company’s operating performance and ability to generate cash flow. In addition, the Compensation Committee of the Board of Directors uses AISC per ounce sold, together with other

13

measures, in its Corporate Scorecard to set incentive compensation goals and assess performance. The most directly comparable IFRS measure is production costs.

Sustaining and Growth Capital

Sustaining and growth capital are non-IFRS financial measures. The Company defines sustaining capital as capital required to maintain current operations at existing levels, including capitalized stripping and underground mine development. Sustaining capital excludes non-cash sustaining lease additions, unless otherwise noted, and does not include capitalized interest, expenditure related to capitalized evaluation, development projects, or other growth or sustaining capital not related to operating gold mines. Growth capital is defined as capital expenditures for new operations, major growth projects or enhancement capital for significant infrastructure improvements at existing operations. The Company uses sustaining capital to understand the ongoing capital cost required to maintain operations at current levels, and growth capital to understand the cost to develop new operations or related to major projects at existing operations where these projects will materially increase production from current levels. The most directly comparable IFRS measure is additions to property, plant and equipment.

Average Realized Gold Price per Ounce Sold

Average realized gold price per ounce sold is a non-IFRS financial measure. The Company defines average realized gold price per ounce sold as revenue from gold sales adding back treatment charges, refining charges, penalties and other costs that are deducted from proceeds from gold concentrate sales, divided by gold ounces sold in the period. The definition of average realized gold price per ounce sold changed in Q1 2022 to add back to revenue certain costs that are deducted from proceeds from gold concentrate sales. These include treatment charges, refining charges, penalties and other costs. In prior periods these costs reduced average realized gold price per ounce sold. As these costs are included in cash operating costs (defined above), this adjustment to average realized gold price per ounce sold will result in greater comparability between metrics. Average realized gold price per ounce sold for 2021 and earlier periods has been adjusted to conform with presentation in subsequent periods. The Company uses average realized gold price per ounce sold to better understand the price realized in each reporting period for gold sales. The most directly comparable IFRS measure is revenue.

Free Cash Flow

Free cash flow is a non-IFRS financial measure. The Company defines free cash flow as net cash generated from (used in) operating activities of continuing operations, less net cash used in investing activities of continuing operations before increases or decreases in cash from the following items that are not considered representative of our ability to generate cash: term deposits, restricted cash, cash used for acquisitions or disposals of mineral properties, marketable securities and non-recurring asset sales. The Company discloses free cash flow as it believes this measure is a useful indicator of its ability to operate without reliance on additional borrowing or usage of existing cash. The most directly comparable IFRS measure is net cash generated from (used in) operating activities of continuing operations.

Working Capital

Working capital is a non-IFRS financial measure. The Company defines working capital as current assets less current liabilities. Working capital does not include assets held for sale and liabilities associated with assets held for sale. The Company discloses working capital as it believes this measure is a useful indicator of the Company’s liquidity. The most directly comparable IFRS measures are current assets and current liabilities.

Environmental, Social and Governance

Governance

Eldorado focuses on contributing to the sustainable development of the communities and regions where we work by fostering safe, inclusive and innovative operations, engaging with communities, responsibly producing products and maintaining or restoring healthy natural environments. We implement technology in regards to environmental practices such as dry-stack tailings, and invest in building capacity in areas such as infrastructure, education and healthcare to create a positive lasting legacy everywhere we operate.

Our governance systems, including policies, frameworks and transparent disclosure practices underpin our environmental, social and governance (“ESG”) efforts. The Board of Directors works to utilize the diverse perspectives and experiences of directors in its oversight of Eldorado’s business and sustainability activities, and has increased its focus on integrating sustainability performance into governance models and compensation. Corporate governance and a commitment to transparency are the core of our business. Eldorado Gold’s Sustainability Committee and Corporate Governance and Nominating Committee of the Board of Directors are responsible for overseeing Eldorado’s ESG activities.

Eldorado Gold’s Sustainability Committee comprises selected members of the Board of Directors. Their task is to oversee and monitor the environmental, health, safety, social, human rights and other sustainability policies, practices, programs and performance of the Company. The Sustainability Committee is also responsible for overseeing matters related to climate change. The whole Board is aligned with management in ensuring we provide our people with safe, healthy and secure workplaces.

ESG Frameworks

Since the introduction of SIMS in 2021, the focus of Eldorado has been implementation of the standards and completing integrated assurance at our operating sites, which includes verification against SIMS, Responsible Gold Mining Principles and Towards Sustainable Mining standard. Lamaque and Olympias were verified in 2022 and 2023, respectively. Kışladağ and Efemçukuru are expected to be verified in 2024. Lamaque achieved AAA ratings, the highest possible score, across all indicators in Biodiversity, Tailings and Water. Olympias achieved AAA ratings across all indicators in Tailings and Biodiversity. Assured scores are available publicly on Mining Association of Canada’s TSM website.

Eldorado engaged an independent third-party to conduct Human Rights Assessments across all of its operating jurisdictions, and those assessments were completed by 2022. As per SIMS, we will repeat these assessments every 3 years. The next assessments are planned for 2025.

Eldorado also developed a Climate Change Strategy and continued the development and implementation of an Energy and Carbon Management System through setting climate-related targets and operationalizing governance, management, and programs related to climate change mitigation and adaptation. In February 2022, Eldorado published its first Climate Change & GHG Emissions Report (the “Climate Change Report”) aligned with the Task Force on Climate-Related Financial Disclosures (“TCFD”). The Climate Change Report details Eldorado’s governance, management, risks, strategy, metrics and targets related to climate change. Effective January 1, 2024, Eldorado Gold and Eldorado Quebec are also subject to Canada’s new “Fighting Against Forced Labour and Child Labour in Supply Chains Act (the “Modern Slavery Act”). Eldorado is committed to meeting its obligations under the Modern Slavery Act. Later this year, Eldorado will be preparing and delivering the necessary disclosure document listing, among other things, steps that Eldorado has taken to prevent and reduce risks of forced labour and child labour.

Health, Safety and Environmental Initiatives

The health and safety of our employees and local affected parties is a key priority of Eldorado.We are committed to the high health and safety standards, adhere to stringent safety regulations and have systems in place to promote a culture of safety.

Eldorado is committed to supporting the protection of international human rights through best practices in all of our business activities. While governments have the primary responsibility for protecting and upholding the human rights of their citizens, Eldorado recognizes its responsibility to respect human rights everywhere we operate. In addition, we recognize that we have an opportunity to promote human rights where we can make a positive contribution. Eldorado adheres to the World Gold Council’s Conflict Free Gold Standard, and produces an annual externally-assured Conflict Free Gold Report confirming that the Company’s operations do not contribute to unlawful armed conflict or human rights abuses.

Eldorado’s properties are routinely inspected by regulators to determine that the properties are in compliance with applicable laws and regulations. In addition, Eldorado conducts internal inspections and participates in external audits to assess the Company’s conformance with its policies and standards.

Our tailings facility monitoring programs include collecting and analyzing geotechnical, hydrological and environmental data from across our facilities. Physical inspections by site personnel and external providers are conducted and equipment such as piezometers and other sensors may be used to collect data. The heap leach facilities at our Kışladağ operation are monitored continuously by site operations and geotechnical teams, with frequent physical inspections being performed. Routine surveys of the facilities may be paired with satellite monitoring data to perform analyses to identify any potential deformation that may take place. Our monitoring programs continuously assess the stability of tailings materials as well as dam structures and related infrastructure.

In accordance with the Mining Association of Canada’s Guide to the Management of Tailings Facilities, as well as applicable regulations in the jurisdictions where we operate, our tailings facilities regularly undergo third-party inspections by experts and government authorities. In 2021, Eldorado established an independent tailings review board (ITRB) to provide technical guidance on design and operational practices. The third party inspections and independent reviews assess the stability and structural integrity of our tailings facilities and note improvements that may be made to further mitigate risks. For further information about Eldorado’s tailings facilities, please see our “Tailings Facilities and Stewardship Overview”, which has been produced in accordance with the Church of England Pension Fund and the Swedish Council (https://www.eldoradogold.com/responsibility).

Prior to and throughout a mine’s operation, we conduct research to establish best practices for mine reclamation and closure. Whenever possible, remediation and reclamation will begin in parallel with other work being carried out across the mine. After a mine site is permanently closed, we conduct further environmental monitoring and reclamation activities, as required by the mine’s EIA and mine licenses. Eldorado also has closure plans for all of its operations. These closure plans assist us to properly estimate the key activities and costs associated with implementing the required closure provisions.

More information on our health and safety, social, and environmental initiatives can be found on our website.

The Kışladağ Technical Report is available under Eldorado Gold’s name on SEDAR+ and EDGAR.

Property Description, Location and Access

The Kışladağ gold mine has been an operating open pit mine in commercial production since 2006 with surface facilities consisting of a crushing plant, heap leach pads and an adsorption, desorption, regeneration (ADR) plant, along with ancillary buildings.

Kışladağ is located in west-central Türkiye lying 180 km to the east of the Aegean coast between Izmir and Ankara. The Kışladağ Project site lies 35 km southwest of the city of Uşak, which has a greater area population of approximately 370,000 inhabitants and near the village of Gümüşkol. Access to the mine is via the main highway towards Ankara from Uşak, and a secondary highway 35 km southwest towards Eşme. A 5.3 km private mine access road connects the mine to the public highway. The mine site sits on the western edge of the Anatolian Plateau at an elevation of approximately 1,000 m, in gentle rolling topography. The climate in this region is arid with warm dry summers and mild wet winters.

There are no permanent water bodies in the area and water supply is limited to ephemeral streams and shallow seasonal stock ponds. Water is supplied to the mine from various well fields with a capacity of approximately 280 m3/hr. A dam was constructed in partnership with the water authority in 2016 and is connected to the site to serve as an additional reservoir to support operations.

The Turkish Electricity Distribution Corporation provides power to the site via two transmission lines from the Uşak industrial zone, 154 kV (27.7km) and 34.5 kV (25km).

The Kışladağ Project land position consists of a single operating license, number 85995, with a total area of 17,192 ha. According to Turkish mining law, Tüprag retains the right to explore and develop any mineral resources contained within the license area provided fees and taxes are maintained. The license was issued on April 9, 2003 and renewed on May 10, 2012 and is currently set to expire on May 10, 2032. Duration of the mining license can be extended if the mine production is still going on at the end of the license period.

No environmental liabilities have been assumed with the Kışladağ Project.

The current project’s EIA area covers 2,509 ha. The land is classified as forestry (49%), treasury (7%), with the remaining area belonging to private land holders. As of December 31, 2023, Tüprag is the majority owner of private land within the concession.

Mining licenses in Türkiye are divided into 5 groups. The Kışladağ license is in group 4, which includes gold, silver, and platinum mines. Royalty rates for group 4 licenses are calculated on a sliding scale implemented in 2015. Royalty rates are based on the run of mine (ROM) sales price. The ROM sales price is calculated by subtracting processing, transport, and depreciation costs from the gold and silver revenues. This amount is then multiplied by the appropriate royalty rate. The royalty rates are

17

determined once a year by the General Directorate of Mines based on the average sales price of gold and silver quoted on the London Metal Exchange. Doré produced at Kışladağ is considered to be the product of ore processing and is eligible for a factored royalty rate. The corporate tax rate in Türkiye is 25%.

Table 1-1:Royalties Calculation

Average Annual Gold Price ($/oz)	Royalty (%)	Factored Royalty (%)
901 - 1000	3.75%	2.25%
1001 - 1100	5.00%	3.00%
1101 - 1200	6.25%	3.75%
1201 - 1300	7.50%	4.50%
1301 - 1400	8.75%	5.25%
1401 - 1500	10.00%	6.00%
1501 - 1600	11.25%	6.75%
1601 - 1700	12.50%	7.50%
1701 - 1800	13.75%	8.25%
1801 - 1900	15.00%	9.00%

2001 - 2100	17.50%	10.50%
> 2100	18.75%	11.25%

With an average realized gold price at Kışladağ for 2023 of $1,953, the applicable factored royalty rate was 9.75%.

There are no other royalties, overrides, back-in rights, payments or agreements or encumbrances to which the Kışladağ mine is subject. There are no known significant factors or risks that might affect access or title, or the right or ability to perform work on the Kışladağ mine, including permitting and environmental liabilities to which the project is subject.

History

In-depth exploration began in 1997. More recently in 2020, the Company announced a revised mine plan encompassing a 15-year mine life at Kışladağ supported by new Mineral Reserve estimates that were based on the completed long-cycle heap leach testwork and the replacement of the tertiary crushing circuit with a HPGR circuit. As a result of the decision to not advance with construction of a mill, an impairment reversal of $100.5 M was recognized as at December 31, 2019 relating to the previous impairment of the leach pad and related plant and equipment. An additional impairment charge of $15.3 M was also recorded as at December 31, 2019 relating to capitalized costs of the mill construction project.

Geological Setting, Mineralization and Deposit Types

Kışladağ gold mine is a gold-only porphyry deposit located in the eroded Miocene Beydağı stratovolcano in western Türkiye. Gold mineralization is centered on a set of nested subvolcanic porphyritic intrusions (monzonites and quartz monzonites) that were emplaced through the underlying Menderes metamorphic basement rocks into the base of the Beydaǧı volcanic cover.

Five intrusions have been distinguished based on crosscutting relationships: 1, 2 central, 2A, 2 NW, and 3. All the intrusions have a similar mineralogy and are dominated by plagioclase phenocrysts, with subordinate biotite and amphibole phenocrysts. K-feldspar occurs in minor quantities as phenocrysts but is typically the dominant phase in the groundmass. Intrusions 1 and 3 contain sparse quartz phenocrysts, and clinopyroxene was identified in intrusions 2 central, 2 NW, and 3. Strong hydrothermal alteration in intrusion 1, and especially intrusion 2A, makes the identification of primary mineral assemblages difficult. Stratigraphic layering dips gently radially outward from the eroded center of the volcanic system, with no evidence of fault-related tilting. At depth, the composite porphyry intrusions extends beyond the current limit of drilling (~1,000 m).

The deposit is associated with five main types of alteration assemblages: (1) potassic alteration focused on intrusion 1 and containing the highest gold grades, (2) sodic-calcic alteration, (3) tourmaline-white mica alteration, (4) advanced argillic alteration, and (5) late retrograde argillic alteration. Potassic alteration is characterized by biotite and K-feldspar ± magnetite and most intensely developed in the center of the deposit in intrusion 1, 2 NW, and 2 central. Sodic-calcic alteration affected the deep parts of

18

the deposit where it overprints the potassic alteration and is characterized by feldspars (including albite), actinolite, biotite, and magnetite ± carbonates. Tourmaline-white mica altered all intrusions but most intensely around the potassic zone. It also occurs in the metamorphic host rocks immediately next to the porphyry intrusions as well as in the volcanic pile within a few hundreds of meters around the deposit. Tourmaline is also abundant in the matrix of breccias in and around the deposit. These tourmaline breccias can be well mineralized where they contain coarse-grained pyrite. Advanced argillic alteration (quartz-alunite ± pyrophyllite ± dickite ± pyrite) is most abundant as a lithocap on the eastern side of the deposit. It also occurs along fracture-controlled zones and especially along stratigraphic contacts in the volcanic rocks around the deposit. Poorly mineralized advanced argillic alteration is present in all the intrusions and overprinted potassic and tourmaline-white-mica alteration. Pyrite has largely been oxidized to jarosite in the shallower parts of the deposit. The pervasively developed argillic alteration assemblage is dominated by kaolinite-smectite (mainly montmorillonite and nontronite) and overprinted all other alteration assemblages. It is widely distributed throughout the deposit, particularly at shallow levels, as well as in the surrounding volcanic rocks. The largest and strongest zone of argillic alteration in the deposit is focused on intrusion 2A.

Veinlets mainly occur as a low-density stockwork and show a temporal evolution from quartz-K-feldspar, quartz-pyrite, quartz-pyrite with tourmaline alteration halos in potassic alteration, pyrite-tourmaline in tourmaline-white-mica alteration, to pyrite-only veinlets cutting all other veins. Pyrite ± tourmaline veinlets are the most abundant in the deposit, and quartz veinlets are volumetrically minor. Molybdenite, chalcopyrite, and galena occur as minor phases associated with these veinlets. Molybdenite is dominantly associated with quartz-bearing veinlets in the shallower parts of the potassic zone. In the upper parts of the deposit, gold occurs mainly as nonrefractory, fine (10 μm) grains associated with pyrite, whereas in the deeper parts, within the potassic and sodic-calcic alteration zones, gold is dominantly included in the feldspar grains associated with pyrite.

Exploration

Tüprag discovered the Kışladağ deposit in the late 1980’s during a regional grassroots exploration program focusing on Late Cretaceous to Tertiary volcanic centres in western Türkiye. It selected the prospect area on the basis of Landsat-5 images that had been processed to enhance areas of clay and iron alteration, followed by regional stream sediment and soil sampling programs. Preliminary soil sampling programs identified a broad 50 ppb gold anomaly within a poorly exposed area now known to directly overlie the porphyry deposit. Early exploration of the deposit area included excavation of trenches to better characterize the soil anomaly, and ground geophysical surveys including IP-resistivity, magnetic and radiometric surveys.

Subsequent exploration work was limited to a regional airborne geophysical survey that included the Kışladağ property as part of the survey grid. No new targets were identified within the license area.

Drilling

Several drilling campaigns by both diamond core drilling and reverse-circulation (“RC”) drilling took place from 1998 through 2016 for a total of 198,000 m of which 38% was drilled in 2007 to 2010 and 26% in 2014 to 2016. It is this later drilling, mostly core holes, that provided information to enable conversion of the Mineral Resource to Reserves.

Diamond drilling in Kışladağ was done with wire line core rigs and mostly of HQ size. Drillers placed the core into wooden core boxes with each box holding about 4 m of HQ core. Geology and geotechnical data were collected from the core and core was photographed (wet) before sampling. Specific Gravity (SG) measurements were done approximately every 5 m. Core recovery in the mineralized units was excellent, usually between 95% and 100%. The entire lengths of the diamond drill holes were sampled (sawn in half by diamond saw). The core library for the Kışladağ deposit is kept in core storage facilities on site. Core recovery in the mineralized units was excellent, usually between 95% and 100%.

No exploration drilling has been undertaken subsequently, and all recent drilling has been for the purpose of ongoing production, geotechnical, or metallurgical requirements.

Sampling, Analysis and Data Verification

Samples were prepared at Eldorado’s in-country preparation facility near Çanakkale in north-western Türkiye. A Standard Reference Material (“SRM”), a duplicate and a blank sample were inserted into the sample stream at every 8th sample. From there the sample pulps were shipped to the ALS Chemex Analytical Laboratory in North Vancouver until April 2015 and Bureau Veritas (formerly Acme Labs) in

19

Ankara since then. All samples were assayed for gold by 30 g fire assay with an AA finish and for multi-element determination using fusion digestion and inductively coupled plasma (“ICP”) analysis.

Monitoring of the quality control samples showed that all data were in control throughout the preparation and analytical processes. In Eldorado’s opinion, the Quality Assurance (“QA”)/Quality Control (“QC”) results demonstrate that the Kışladağ deposit assay database is sufficiently accurate and precise for resource estimation.

Mineral Processing and Metallurgical Testing

Kışladağ has been processing ore from the mine since commissioning in 2006. Based on this long operating history, the operation has developed understanding around ore types and the leaching of its ore.

In 2021, the crushing circuit was modified to replace the tertiary crushers with a high pressure grinding rolls (HPGR) circuit. This modification changed the size distribution of the crushing circuit product that is being fed to the heap leach circuit, and an agglomeration circuit was added. Since commissioning the HPGR, testwork has been undertaken to assess the effectiveness of this fines agglomeration and its effect on solution percolation and recovery rates. Regular column tests are also conducted to validate leach kinetic rates and recoveries.

Mineral Resource and Mineral Reserve Estimates

The Mineral Resources of the Kışladağ deposit were classified using the CIM Definition Standards for Mineral Resources and Reserves (May 10, 2014) that are incorporated by reference into NI 43-101. The mineralization of the project satisfies sufficient criteria to be classified into Measured, Indicated, and Inferred Mineral Resource categories.

Inspection of the Kışladağ model and drillhole data on plans and cross-sections, combined with spatial statistical work and investigation of confidence limits in predicting planned annual and quarterly production, contributed to the setup of various distance to nearest composite protocols to help guide the assignment of blocks into Measured or Indicated Mineral Resource categories. Reasonable grade and geologic continuity is demonstrated over most of the Kışladağ deposit, which is drilled generally on 40 m to 80 m spaced sections. Blocks were classified as Indicated Mineral Resources where blocks containing an estimate that resulted from samples spaced within 80 m and from two or more drill holes. Where the sample spacing was about 50 m or less, and the grade estimated were from at least three drill holes, the confidence in the grade estimates and lithology contacts were the highest and were thus permissive to be classified as Measured Mineral Resources.

All remaining model blocks containing a gold grade estimate were assigned as Inferred Mineral Resources.

A test of reasonableness for the expectation of economic extraction was made on the Kışladağ mineral resources by developing a series of open pit designs based on optimal operational parameters and gold price assumptions. A pit design based on $1,800/oz Au and heap leaching was chosen to constrain mineral resources likely to be mined by open pit mining methods. Eligible model blocks within this pit shell were evaluated at an open pit resource cut-off grade of 0.25 g/t Au.

The Kışladağ Mineral Resources as of September 30, 2023 are shown in Table 1-2. The Kışladağ mineral resource is reported at a 0.25 g/t Au cut-off grade with a resource pit shell for Measured, Indicated and Inferred Mineral Resources.

Table 1-2: Kışladağ Mineral Resources, as of September 30, 2023

Mineral Resource Category	Resource (t x 1,000)	Grade Au (g/t)	Contained Au (oz x 1,000)
Measured	286,037	0.61	5,585
Indicated	44,280	0.50	705
Measured & Indicated	330,317	0.59	6,290
Inferred	7,529	0.44	107

The operation uses conventional open pit techniques to feed crushing and heap leaching circuits to process the ore. The Mineral Reserves reported in this section are based upon the operation with the HPGR since 2021.

The open pit optimization and pit design was completed using MineSight (MinePlan) software with comparative checks using Whittle® software. No dilution was included in the conversion of Mineral Resources to Mineral Reserves as the block modelling methodology (probability assisted constrained kriging) already accounts for dilution. Wall slope design incorporated inter-ramp slope angles by the usage of 15 sectors, created from analysis and modelling of geotechnical data collected over multiple years.

The Mineral Reserves for the deposit were estimated using a gold price of US$1,400/oz and are effective September 30, 2023. The Mineral Reserves are reported using a cut-off grade of 0.17 g/t recoverable gold grade for ore that will be processed by heap leaching. Mineral reserves are summarized in Table 1-3. The Mineral Reserves as reported are derived from and are included in the Mineral Resources.

Table 1-3: Kışladağ Mineral Reserves as of September 30, 2023

Mineral Reserves Category	Ore (t x 1,000)	Grade Au (g/t)	Contained Au (oz x 1,000)
Proven	163,085	0.68	3,543
Probable	13,491	0.50	216
Proven & Probable	176,576	0.67	3,759

Mineral Resource and Mineral Reserve estimates for Kışladağ may be affected by technical and other relevant factors which are more specifically described in our "Risk Factors" section.

Mining Operations

Kışladağ is a large tonnage, low grade operation. Mining and processing activities operate 24 hours a day, seven days a week. The mining operation is a standard truck and shovel operation using owner-operated equipment and labour. All mined rock requires blasting. The blast holes are sampled and analyzed in-house for detailed grade control.

Processing and Recovery Operations

Ore is processed in a standard heap leach facility as follows:

•Ore is fed into a three-stage crushing and screening plant, with two stages of conventional crushing and the third stage being the HPGR.which is coupled with an oversize screen for edge product recirculation for size reduction as fine as 80% passing 6.3 mm. Crushed ore is transported via overland conveying and stacked on the leach pad with a radial stacker in 10 m high lifts;

•The heap leach pad has a two-part liner system consisting of a layer of compacted low permeability clay soil or geosynthetic clay liner, and a 2 mm thick polyethylene membrane liner textured on both sides for stability toe areas, and for regular areas non-textured or in some cases single sided textured linear low density polyethylene synthetic liner. HDPE liner is also used where the membrane will be subjected to sunlight for an extended period. The current permitted stack height is 120 m, increased from 60 m as a result of the 2014 EIA addendum. Interlift liners are installed within the leach pad to control loaded leach solution contact with spent ore. Leaching currently occurs on both the SHLP and NHLP.

•Reagents used in leaching include lime, cyanide and cement. Ore is leached with diluted cyanide solution applied by drip emitters; gold is recovered in a conventional ADR circuit, using carbon-in-column (CIC) trains and a standard Zadra process including pressure stripping, electrowinning and smelting; and

•The final product is a gold doré bar, which sees further processing to 99.95% purity in domestic refineries.

In Q1 of 2021, two additional CIC trains were installed successfully. The installation of a new carbon regeneration kiln was completed in Q2 of 2021 to support improved gold recoveries in the circuit. The HPGR circuit reached commercial production in December 2021. Throughout 2022, belt agglomeration using cement was undertaken to improve leaching permeability; 54” materials handling equipment was added to improve the stacking rate on the pad. NHLP construction continued throughout 2022 and was

21

ready for stacking in the second half of 2023. In 2023, a fine ore in-plant agglomeration circuit was installed to further optimize and improve the heap leach performance.

In 2023, Kışladağ stacked 13.2 Mt of ore and produced 154,849 ounces of gold.

Infrastructure, Permitting and Compliance

The Kışladağ Project does not expect to upgrade the existing access road, power or water supplies. The NHLP facility, process and collection ponds were constructed approximately 600 m north of the SHLP and accessed by an extension of the overland conveyor from the SHLP to the NHLP. Construction of the North ADR facility commenced in 2023 and will continue in 2024. Activated carbon that is used to adsorb gold from the NHLP solutions is currently transferred to the South ADR facility for desorption and regeneration.

The South Waste Rock Dump (SWRD) is now closed and under progressive rehabilitation for closure. The new North Waste Rock Dump (NWRD) on the mountain west of the leach pads is now operational. Designed to a capacity of 200 Mt, there will be sufficient capacity to hold the waste rock generated in the current mine plan. The NWRD can be expanded to contain more waste rock if necessary.

The site is bounded by a series of collection ditches to divert non-contact water around the site to reduce the volume of contact water. All contact water is collected from the mine site and pit inflows and sent to collection ponds at the water treatment plant. The treatment plant is located north of the existing South ADR plant with a capacity of 625 m3/hr. On site there are numerous ponds to collect process streams (loaded and unloaded solutions at the ADR plant), contact water, non-contact water, and surge ponds for storm events. The ponds were sized based on a 100-year storm event with additional capacities for storage and process surges.

Capital and Operating Costs

Capital costs at Kışladağ consist primarily of the continued development of the North Heap Leach Pad, North Waste Rock Dump, and North ADR as well as waste stripping in the open pit. Overall capital costs for the life-of-mine (LOM) are summarized in Table 1-4.

Table 1-4: Kışladağ Capital Cost Summary

Growth Capital	LOM Total (US$)
Waste Stripping	269.6
North Heap Leach Pad, North Waste Rock Dump, North ADR	93.7
Other	153.4
Subtotal	510.0
Sustaining Capital
Mine	83.4
Process	10.5
Administration / Finance / Environmental / Health & Safety	6.7
Sustaining Capital Construction	19.4
Subtotal	120.0
Total Capital Costs	630.0

Operating costs were estimated based on actual 2023 operating costs and 2024 budget estimates. Mining costs include all consumables and equipment required to meet the production schedule objectives. Labour requirements were developed to support the operation and maintenance of the fleet and for the general operation of the mine area. All these estimates align with manpower levels.

Process operating costs were based on current annual consumption of process reagents, major wear parts, and utilities. General and administrative costs are based on current personnel requirements and salaries. Unit rates representative to a steady state production profile are summarized in Table 1‑5.

Table 1‑5: Operating Cost Summary

Area	Unit Costs (US$/t processed)
Mining	$2.66
Processing	$4.63
Site General & Administrative	$2.78
Total Mine Operating Costs	$10.07

Production, cash operating cost per ounce, and sustaining capital for 2023 and forecasts for 2024 are as follows in Table 1-6:

Table 1‑6: Production, Cash Cost, and Sustaining Capital Summary

	2023	2024 Forecast
Production	154,849 oz	180,000 -195,000 oz
Cash Operating Cost per ounce sold	$657
Total Cash Cost per ounce sold1		$ 820 – 920
Sustaining Capital	$ 16.0 M	$ 10 - 15 M

1 As we have issued AISC/oz guidance by site in 2024, in addition to continuing total cash cost/oz guidance, we have previously announced that we will cease reporting of cash operating cost/oz in Q1 2024. The table above therefore reflects historic and forecasted reporting metrics, which will not be directly comparable.

In 2024, Kışladağ is expected to mine and place on leach approximately 13.2 to 13.6 million tonnes of ore at an average gold grade of 0.70 to 0.80 g/t. Total cash costs are expected to be slightly higher, when compared to 2023, driven primarily by higher mining rates and increased labour costs. Consumption of fuel, explosives, cement, and cyanide are also expected to increase, impacting absolute costs.

Planned 2024 sustaining capital of $10 to $15 M is primarily related to equipment overhauls and processing improvements. Planned 2024 growth capital of $85 to $95 M includes the continuation of the waste stripping campaign, the phased expansion of the NHLP, and construction of the North ADR plant.

Efemçukuru

Technical Report

The scientific and technical information regarding Efemçukuru in this AIF is primarily derived from or based upon the scientific and technical information contained in the technical report titled “Technical Report, Efemçukuru Gold Mine, Türkiye]” with an effective date of December 31st, 2023 prepared by David Sutherland, P.Eng, Peter Lind, P.Eng., Mike Tsafaras, P.Eng., Sean McKinley, P.Geo, and Ertan Uludag, P.Geo, all of whom are “Qualified Persons” under NI 43-101. The report is available under Eldorado Gold’s name on SEDAR+ and EDGAR. David Sutherland, Peter Lind, Mike Tsafaras, Sean McKinley, and Ertan Uludag are all employees of the Company.

Property Description, Location and Access

The Efemçukuru mine has been an operating underground mine in commercial production since 2011. Facilities at the mine consist of an underground crushing plant, milling and flotation plant, filtration and paste backfill plant, water treatment plant, and ancillary buildings.

The mine is located near the village of Efemçukuru in the İzmir province in western Türkiye, approximately 20 km southwest of the city of İzmir. The mine site is accessed via paved roads directly to the site. All water is sourced from contact water; all contact water discharged is treated before release. Power is supplied from the local grid with sufficient capacity for current and future operations.

The Efemçukuru mine land position consists of a single operating license (number 51792) with a total area of 2261.49 ha. According to Turkish mining law, Tüprag retains the right to explore and develop any mineral resources contained within the license area provided fees and taxes are maintained. The license was issued on April 20, 1999 and renewed on August 19, 2013; it is currently set to expire on August 19, 2033. Within the 126.6 ha operating area, forestry land makes up about 80%, treasury land makes up approximately 1%, and the remaining area is private land wholly owned by Tüprag.

No prior environmental liabilities have been assumed with the Efemçukuru Project. Capital cost allowances have been made in respect of estimated closure costs. Efemçukuru is fully permitted with no additional permits currently required. All infrastructure required to mine and process the Mineral Reserves disclosed in this report fall under the scope of the existing EIA and operating license.

Mining licenses in Türkiye are divided into five groups.The Efemçukuru mine operating license belongs to group 4, which includes gold, silver, and platinum mines.Royalty rates (Table 1-1) for group 4 licenses are calculated on a sliding scale implemented in 2019 by the Republic of Türkiye Ministry of Energy and Natural Resources.The rates are revised periodically and are based on the run of mine (“ROM”) sales price.The ROM sales price is calculated by subtracting processing, transport, and depreciation costs from the gold and silver revenues.This amount is then multiplied by the appropriate royalty rate.The royalty rates are determined once a year by the General Directorate of Mines based on the average sales price of gold and silver quoted on the London Metal Exchange (LME).Concentrate produced at the Efemçukuru mine is considered the product of ore processing and is eligible for the 40% reduction in the royalty rate. The royalty rate for Efemçukuru in 2023 was approximately 9.75% at an average gold selling price of $ 1,941/oz. The corporate tax rate in Türkiye is 25%.

There are no other royalties, overrides, back-in rights, payments or agreements or encumbrances to which the Efemçukuru mine is subject. There are no known significant factors or risks that might affect access or title, or the right or ability to perform work at the Efemçukuru mine, including permitting and environmental liabilities to which the project is subject.

History

The Efemçukuru Deposit was discovered by Tüprag in 1992, while carrying out reconnaissance work in western Türkiye. Ancient workings were identified in the deposit and it was concluded that the area was likely mined during the Roman dynasty two thousand years ago. Later in the early 20th century, a British company owned the exploration rights and undertook limited surface work on the Efemçukuru deposit. No modern work was completed on the property before Tüprag’s acquisition of the property.

The Efemçukuru mine started commercial production in June 2011, and annual ore production ramped up from 435 kt to 545 kt with no major changes to the operation.

Geological Setting, Mineralization and Deposit Types

Western Anatolia, Türkiye, is host to several major porphyry and epithermal gold deposits. The gold-rich region is part of the Western Tethyan orogen. The Efemçukuru deposit is hosted in the centre of a broadly NE-SW trending upthrown block known as the Seferihisar Horst, which regionally exposes basement rocks of the Bornova Flysch in the Menderes Massif.

The intermediate sulfidation veins at Efemçukuru are hosted by quartz, feldspar, muscovite and chlorite bearing schists and phyllites of the Bornova Flysch, with the distinction based on intensity of deformation

24

fabric and relative muscovite abundance. The schists host chlorite-altered spilitic basalt lenses as well as lenses of finely crystalline, massive white marble.

Two major, broadly NW-SE striking epithermal vein systems, namely Kestanebeleni and Kokarpınar, occur at Efemçukuru. They have strike extents of approximately 2 km and 4 km respectively. At surface, the veins are up to 5 m wide, are characterised by banded quartz-rhodochrosite-rhodonite with pyrite-galena-sphalerite and have surface coatings of Mn- and Fe-oxide. The two main veins have complex geometries with multiple shoots and splays. The Kestanebeleni vein is divided into several ore shoots along its strike length, including South Ore Shoot (SOS), Middle Ore Shoot (MOS), North Ore Shoot (NOS) and Kestanebeleni Northwest (KBNW). In the footwall to the Kestanebeleni vein, two similarly oriented but narrower veins are present and termed the Batı veins. The Kokarpınar vein has a more consistent northwesterly strike and dips moderately to the northeast.

The formation of the Efemçukuru gold deposit in western Anatolia coincided with Miocene extension, magmatism and hydrothermal activity including the formation of several other significant gold-rich porphyry and epithermal deposits in the region. Efemçukuru is classified as an intermediate sulfidation epithermal system due to its high-base metal content and the Mn-rich nature of the veins. The dominantly NE dipping Efemçukuru veins formed within faults that had east side down normal‐dextral (right lateral) shear sense. The spatial and temporal distribution of rhyolite, high temperature calc-silicate alteration, and intermediate sulfidation epithermal veins support a magmatic-hydrothermal origin. Detailed carbon and oxygen isotope analysis of vein carbonates indicate a mixed meteoric and magmatic source for the hydrothermal fluids and strongly support degassing and boiling of magmatic fluids during formation of the main epithermal veins.

Exploration

The Turkish Mine Exploration Institute records document Efemçukuru as a manganese occurrence. Modern exploration activity at Efemçukuru were initiated in 1992 when Tüprag geologists recognized the exploration potential of the area while conducting reconnaissance work in western Türkiye.

Exploration since 2010 has focused on the Kokarpınar vein located east of, and subparallel to, the Kestanebeleni vein. In 2018, the Batı veins were discovered in the footwall to the Kestanebeleni vein. Since 2018, the Batı and West veins have been added to the focus of the exploration.

Geological mapping at Efemçukuru has proven to be highly effective for discovering and delineating new veins. Mapping of the underground mine developments is ongoing. Surface and underground mapping, in addition to drill hole logging combined with structural data, have been used to model the vein systems in 3D and help define new mineralized targets around the mine.

Nearly 150 line-km of ground geophysics, including ground magnetic, IP (induced polarization) and gradient IP surveys, have been conducted on the property to assist in mapping and tracing with depth structures, lithologies, alteration domains and sulfides associated with the epithermal veins.

Interpretations from surface mapping, sampling and geophysics have resulted in the identification of additional systems (e.g., Dedebağ, Volkan, Huseyinburnu) in the southwestern part of the property that are collectively called the West veins. These veins, and related blind veins (that are not exposed at surface), have been the focus of exploration drilling in 2023 and remain prospective for the discovery of additional mineralization. Mine exploration from underground has also helped identify new mineralized targets and extensions at Efemçukuru.

Drilling

Several phases of exploration drilling were carried out between 1992 and 1997 to gather geological, geochemical and metallurgical data following discovery of the Kestanebeleni vein. Delineation and further exploration drilling from 2006 to 2008 focussed on the Kestanebeleni NOS. Tüprag continued drilling activity on the Kokarpınar vein area between 2009 and 2011. Drilling in 2011 and 2012 focused on testing the Kestanebeleni vein along strike including KBNW, testing down-dip extensions to the South Ore Shoot (SOS), as well as further defining the geometry and continuity of the Kokarpınar vein. Exploration drilling programs in 2013 through 2017 tested the Kokarpınar vein over a 3 km strike length and identified Mineral Resources in several discrete shoots. Between 2018 and 2021 exploration drilling targeted the expansion of the resource in the Kokarpınar vein and the newly discovered Batı veins. Following this, from 2021 to 2023, drilling continued to delineate the Kestanebeleni, Kokarpınar and Batı veins, and rilling was also undertaken to test the West vein area.

Diamond drilling is essential for infill and delineation to increase the geologic confidence in the mining areas and to improve the grade control model. At Efemçukuru, the gold is not visible and is unevenly

25

distributed along the mineralized vein. Core recovery is typically good and averages 97% in over 92% of core intervals intercepting mineralized zones.

Drilling of a specific area is scheduled to be finished 6 to 8 months prior to mining. This timeline is sufficient for short-term grade model updates and applying any changes to the planned development or stope sequencing prior to planned production from the stope area.

In 2023, drilling at Efemçukuru included 18,084 m of resource conversion drilling and 38,252 m of exploration drilling testing for resource expansion and early-stage targets.

Sampling, Analysis, and Data Verification

Most diamond drilling since production commenced at Efemçukuru mine comprised of infill and delineation drill holes. Drill core is placed into core boxes marked with hole ID, sequence numbering, and depth interval. Sample intervals are selected and marked up by the logging geologist. Drill core samples are either cut with a diamond rock saw (if a delineation hole) or whole core sampled (if an infill hole). Samples are bagged and sent to the nearby ALS analytical laboratory in Izmir for sample preparation, including cataloging, crushing to 90% passing 2 mm, sub-sampling by riffle splitter until approximately 1 kg remains, and then pulverizing of the sub-sample to 90% passing 75 microns.

Exploration core samples are assayed for gold by 50 g fire assay and underground core samples are assayed for gold by 30 g fire assay with an atomic absorption (AA) finish. All samples are assayed for multi-element determination using fusion digestion and inductively coupled plasma (ICP) spectroscopy analysis. A comprehensive QA/QC program is carried out as part of the assaying procedure, involving regular insertion of Certified Reference Materials (CRMs), duplicates and blank samples. The procedure includes inserting either a CRM, blank, or duplicate into the sample stream of every eighth sample. Site geologists regularly monitor the performance of CRMs, blanks, and duplicates as the assay results arrive on site.

Assay results are provided to Eldorado in electronic format and as paper certificates. Upon receipt of assay results, values for CRMs and field blanks are tabulated and compared to established CRM pass-fail criteria. Laboratory check assays are conducted at the rate of one per batch of 20 samples, using the same QA/QC criteria as routine assays. In addition, the ALS laboratory is regularly visited by the site geology team to observe and check that stated procedures are being used.

The site geology team regularly monitors the performance of CRMs, blanks and duplicates as the assay results arrive on site. Eldorado implemented a program that monitors data from regularly submitted coarse reject duplicates. The data indicates no bias in the assay process or in the analyses.

In the Qualified Person’s opinion, the QA/QC results demonstrate that the Efemçukuru mine’s assay database is sufficiently accurate and precise for the resource estimation. All of the Qualifed Person’s carried out verification of data pertaining to the sections for which they are responsible.

Mineral Processing and Metallurgical Testing

The Efemçukuru concentrator has been processing ore from the mine since commissioning in 2011. Based on this long operating history, the operation has developed understanding around blending different feed materials coming from various ore shoots to match overall processing capacity, in particular sulfide content.

Metallurgical testwork has been carried out on ore samples from future ore zones within the Kokarpınar and Batı veins. This testwork has included comminution testing, to confirm that the future ore feeds can be milled at the required throughput rate. Flotation tests have also been carried out to assess the expected quality of future concentrates and any additional blending requirements that may be necessary.

Deleterious elements that have been identified during testwork and from operational performance include moderate levels of arsenic and halides (chlorine and fluorine). The introduction of column flotation has been positive in terms of rejecting gangue from the final concentrate and thereby reducing the concentrations of halides. Arsenic levels are manageable within the expected ranges required to meet sales contract specifications. Base metals (lead and zinc) can be deleterious or provide some addition value depending on the specific sales contract and method of downstream processing.

Mineral Resources and Reserves Estimates

The Mineral Resource estimates for Efemçukuru consist of 3D block models formed on the Kestanebeleni, Kokarpınar, and Batı epithermal vein systems. Creation of these models utilized a commercial mine planning software package (Geovia Gems). Currently, mining only occurs within the Kestanebeleni vein system with underground development currently underway to the Kokarpınar vein. Gold mineralization at Efemçukuru, primarily occurring in the principal veins, can only be confirmed through assays. By necessity, domains to control grade interpolation are grade based. For the Efemçukuru mineralization, creation of the modelling domains used a 2.0 g/t Au grade threshold and general vein geometry. An examination of the risk posed by extreme gold grades showed that this risk does exist but was mitigated by a series of assay gold grade caps (40 to 200 g/t). Prior to grade interpolation, the assay data were composited into 1-m fixed length composites.

Modelling consisted of grade interpolation by ordinary kriging for Kestanebeleni domains and inverse distance weighting (IDW) to the second power in the remainder of the zones where data was too limited to create correlograms. Nearest-neighbour (NN) grades were also interpolated for validation purposes. No grades were interpolated outside the modelling domains. The search ellipsoids were oriented preferentially to the orientation of the vein in the respective domains. A two-pass approach was instituted for interpolation. The first pass required a grade estimate to include composites from a minimum of two holes from the same estimation domain. The second pass allowed a single hole to place a grade estimate in any block that was uninterpolated from the first pass. The gold model was validated by visual inspection, checks for global bias and local trends, and for appropriate levels of smoothing (change-of-support checks).

The Mineral Resources of the Efemçukuru mine were classified using the CIM Definition Standards for Mineral Resources and Reserves (May 10, 2014) that are incorporated by reference into NI 43-101. The mineralization of the Efemçukuru Project satisfies sufficient criteria such that it can be classified into Measured, Indicated, and Inferred Mineral Resource categories.

Efemçukuru Mineral Resources, as of September 30, 2023, are shown in Table 1‑2. Mineral Resources were restrained by 3D volumes whose design was guided by the reporting cut-off grade of 2.5 g/t Au, contiguous areas of mineralization and mineability. Only material internal to these volumes was eligible for reporting.

The Mineral Reserves of the Efemçukuru mine were classified using the CIM Definition Standards for Mineral Resources and Reserves (May 10, 2014) that are incorporated by reference into NI 43-101. The mineralization of the project satisfies sufficient criteria to be classified into Proven and Probable Mineral Reserves. Only Measured and Indicated Mineral Resources were converted, using appropriate modifying factors, to Mineral Reserves. The Mineral Resources include Mineral Reserves.

The Mineral Reserve estimate is summarized in Table 1‑3 and has an effective date of September 30, 2023.

Mineral Resource and Mineral Reserve estimates for Efemçukuru may be affected by technical and other relevant factors which are more specifically described in our "Risk Factors" section.

Mining Operations

The Efemçukuru mine has produced 5.8 Mt of ore at an average grade of 7.1 g/t Au as of December 31 2023, using a combination of Drift-and-Fill (DAF) and Longhole Open Stoping (LHOS) methods. Break-even cut-off values of $126.60/t for Drift-and-Fill mining and of $123.62/t for LHOS were calculated based on the 2024 budget costs and a steady state LOM production profile. The 2024 budget costs are supported by 2023 actual production costs. Use of the Deswik Stope Optimizer software identified potentially mineable material in the form of mining shapes for both DAF and LHOS mining methods. Dilution was captured as internal dilution (mining shape) and planning (overbreak), the latter equaling 16%. A mining recovery factor of 97% was also implemented. Both factors are supported by regular reconciliation and stope closure exercises.

Efemçukuru mine employs small-scale underground mechanized mining methods to exploit the narrow, high-grade, subvertical mineralization. The projected mine life is six years at the current production rate of 545 ktpa.

The current mine layout has the following features:

•Six declines (SOS, MOS, NOS, KBNW, Kokarpınar Ore Shoot, and Batı Ore Shoot), each covering approximately a 400-m strike extent.

•Two surface portals (south and north).

•One surface conveyor adit for conveying crushed ore to the surface crushed ore bins.

•Five primary ventilation surface exhausts (south, central, north, northwest, and Batı) and three fresh air raises for NOS, Kokarpınar, and Batı.

•Link drives connect declines and serve as a secondary egress from the mine.

The mine plan is based on the combination of DAF and LHOS methods. Both DAF and LHOS stopes are mined concurrently from multiple production blocks to fulfil production requirements. The production blocks are mined in a top-down sequence, but stopes within a production block are mined bottom-up (overhand).

A geotechnical domain model has been developed and updated for geotechnical logging of exploration and stope definition drilling information. At Efemçukuru, the rock mass has been classified by the widely used Q-System by adopting characterization logging values to determine Q‑input parameters. The selection of DAF and LHOS mining methods is primarily based on the orebody geometry (width and dip) and the expected ground conditions determined through geotechnical assessment. Regular geotechnical assessments indicate that the current mining method, stope sizes, and mining sequence will not change significantly over the LOM.

The mine operates seven days a week and three shifts a day. This annual schedule is equivalent to 365 days per year of operation.

Processing and Recovery Operations

The Efemçukuru operation is an underground mine with facilities consisting of an underground crushing plant, milling and flotation plant, filtration and paste backfill plant, water treatment plant, and ancillary buildings. The process plant produces a gold-containing bulk sulphide flotation concentrate. Major sulfide minerals comprise pyrite, sphalerite, and galena.

28

Ore is ground to a P80 target of 54 µm. The reagents used in flotation are sodium bisulfite (NaHS) as sulfidizing agent, copper sulfate (CuSO4.5H2O) as activator, xanthate (SIBX) as collector, S-8045 as promoter, and OrePrep F-549 as frother. In most cases, gold recovery is proportional to sulfur recovery and has averaged between 93 to 94% in recent years.

Run-of-mine ore is crushed underground and transferred to two ore storage bins on surface via a conveyor. The two ore storage bins allow for blending of different ore types feeding the process plant to target a desirable gold / sulfur ratio and reduce contents of penalty elements for concentrate sales.

The comminution circuit consists of a semi-autogenous grinding (SAG) mill operated in closed circuit with a pebble crusher, a ball mill operated in closed circuit with hydrocyclones, and a flash flotation cell. Ball mill discharge is treated in a flash cell to recover the fast-floating liberated sulfide mineral particles and prevent overgrinding of gold containing particles. Overflow from the hydrocyclones is sent to flotation.

The flotation circuit consists of a rougher / scavenger flotation bank and two parallel cleaner flotation banks. Concentrates from the flash flotation cell and the first two cells of the rougher / scavenger bank are combined and upgraded in cleaner bank 1. Rougher cells 3-6 concentrate are treated in cleaner bank 2. Concentrates from cleaner banks 1 and 2 are combined and sent to the final concentrate thickener.

Underflow of the concentrate thickener is filtered, and the filtered concentrate is stored in big bags for shipping. The tailings are sent to a tailings thickener. The final tails are filtered. A portion of the tailings is used in the underground paste backfill plant, and the rest is dry stacked in the tailings storage facility (TSF).

Column flotation as the third cleaner flotation stage was added in 2020 to increase concentrate quality and reduce mass pull with minimal gold recovery loss.

Infrastructure, Permitting and Compliance Activities

The Efemçukuru Project is well established for LOM purposes with all surface infrastructure in place to support the current reserves. Existing ancillary buildings, the warehouse, and administration buildings will continue to be utilized. All power, water supply, water collection and treatment, and road infrastructure exist and will support operations for the reserves at the current throughput.

There are two mine rock storage facilities on site: the central mine rock storage facility (MRSF) - which is in operation - and the south MRSF, construction of which was recently completed. The two facilities have capacity for the current reserves; a third north TSF location is available for future expansion if needed. The central mine rock storage facility (MRSF) is in operation, the south MRSF construction was recently completed, the two facilities have capacity for mining of the current reserves; a north MRSF is planned for future expansion. The operating and constructed facilities have capacity for the current reserves.

Management of the site water will use the existing ponds. The water treatment plant is appropriately sized to include the new facilities. The constructed areas will be sloped and ditched appropriately to tie into the existing systems.

Tüprag has acquired and maintained all permits required to construct and operate the Efemçukuru project. Tüprag conducted baseline studies throughout the early 2000’s prior to development. An EIA was submitted in 2005 and was approved with Environmental Positive Certificate (received / awarded) in September 2005. Since mining began in 2011, Efemçukuru mine operations have routinely collected environmental data outlined in the Environmental Management Plan (EMP) and submitted data to the relevant government agencies. An inspection and monitoring committee has regularly visited the Efemçukuru mine site since 2007. The committee checks if the present mining operations are executed within the applicable laws, regulations, and EIA commitments.

Tüprag submitted applications for revisions to the EIA and received approvals for the revisions in 2015 to allow for larger facilities. The Environmental Licence and Permit for the operation was renewed in June 2023 and is valid until June 2028. The permit covers air emissions, water emissions, and environmental noise while the environmental license addresses the mining waste storage facilities, environmental and geochemical characterization of mining wastes, and potential risks identified. MRSF and TSF areas are designed to address identified risks and licensed as Category B facilities by the Ministry of Environment, Urbanisation and Climate Change (MoEUCC).

Efemçukuru Gold Mine is certified ISO 14001 (Environmental Management System), ISO 45001 (Occupational Health and Safety Management System) and ISO 50001 (Energy Management System). ISO 14001 certificate was first obtained in 2012 and renewed in 2022. ISO 45001 certificate was first obtained in 2019 and renewed in 2022. ISO 50001 certificate was obtained in 2023.

Capital and Operating Costs

Efemçukuru is fully constructed and operating, and actual costs form the basis of future operating and sustaining cost estimates. Mining sustaining capital costs include mine development, paste backfill borehole development, purchase of additional equipment, equipment leasing costs, and health and safety initiatives (Table 1‑4). Additional growth capital cost is included for development of the Kokarpınar and Batı vein system and associated infrastructure required to support mining in these vein systems.

Table 1‑4: Capital Cost Summary

Growth Capital	LOM Total (US$)
Mine Development (Kokarpınar & Batı)	$26.3 M
Mine Infrastructure (Kokarpınar & Batı)	$9.9 M
Exploration and Resource Conversion	$24.9 M
Subtotal	$61.1 M
Sustaining Capital
Mine	$40.9 M
Process	$7.8 M
Administration / Finance (hardware and software)	$1.9 M
Subtotal	$50.6 M
Total Capital Costs	$111.6 M
Closure Costs	$9.8 M

Figures may not add to total due to rounding.

The underground mine operating costs were estimated based on actual 2023 operating costs and 2024 budget estimates that allow for maintaining a steady state production profile. The underground operating costs include all consumables (ground support, explosives, services, cement, aggregates, and fuel) and equipment required to meet the development and production schedule objectives. The operating unit costs for mobile equipment and fuel consumption rates were largely obtained from historic mine data. Labour requirements were developed to support the operation and maintenance of the fleet and for the general operation of the underground mine. All these estimates align with resourcing levels.

General and administrative costs are based on current personnel requirements and salaries. Adjustments have been made if known changes, such as increasing labour, are required in future. General supplies are based on the current operating experience. Process operating costs were based on current annual consumption of process reagents, major wear parts, and utilities. Budget quotations were obtained for supply of all significant consumables and utilities. Power consumption is based on 2023 operating experience. Unit rates representative to a steady state peak production profile are summarized in Table 1‑5.

Table 1‑5: Operating Cost Summary

Area	Unit Costs (US$/t processed)
Mining	43.76
Processing	35.09
Site General & Administrative	37.09
Total Mine Operating Costs	115.95

2023 Summary and 2024 Outlook

Production, cash operating cost per ounce, and sustaining capital for 2023 and forecasts for 2024 are as follows in Table 1-6:

30

Table 1‑6: Production, Cash Cost, and Sustaining Capital Summary

	2023	2024 Forecast
Production	86,088 oz	75,000 - 85,000 oz
Cash Operating Cost per ounce sold	$797
Total Cash Cost per ounce sold		$ 1,080 – 1,180
Sustaining Capital	$ 14.0 M	$ 12 – 17 M

1 As we have issued AISC/oz guidance by site in 2024, in addition to continuing total cash cost/oz guidance, we have previously announced that we will cease reporting of cash operating cost/oz in Q1 2024. The table above therefore reflects historic and forecasted reporting metrics, which will not be directly comparable.

In 2024, Efemçukuru is expected to mine and process approximately 530,000 to 550,000 tonnes of ore at an average gold grade of 5.0 to 5.5 grams per tonne. Total cash costs per ounce sold are expected to be higher, when compared to 2023, and reflect increases in labour costs and consumable costs. Planned sustaining capital expenditures for 2024 of $12 to $17 M include underground development and equipment overhauls. Planned growth capital for 2023 of $6 to $9 M primarily includes development and infrastructure for expansion of the mining area towards the Kokarpınar and Batı vein systems.

Olympias

Technical Report

The scientific and technical information regarding Olympias in this AIF is primarily derived from or based upon the scientific and technical information contained in a technical report prepared by Eldorado titled “Technical Report, Olympias Mine, Greece,” with an effective date of December 31, 2023. The report was prepared by the following Qualified Persons (as defined by NI 43-101): David Sutherland, P.Eng., Peter Lind, P.Eng., Victor Vdovin, P.Eng., Sean McKinley, P.Geo, and Ertan Uludag, P.Geo., who are all “Qualified Persons” under NI 43-101, and is available on SEDAR+ and EDGAR. David Sutherland, Ertan Uludag, Sean McKinley, Peter Lind, and Victor Vdovin are all employees of the Company.

Property Description, Location and Access

The Olympias Property is located within the Kassandra Mines complex located on the Halkidiki Peninsula of Northern Greece, about 100 km by road from Thessaloniki, the second largest city in Greece. There are paved roads directly to the site. The Stratoni port lies 9 km south-southeast of the Olympias mine site and is accessed by a paved road along the coast (26 km). The terrain is characterized by hills rising to about 600 m above sea level, with steeply incised valleys.

The Property consists of mining concession numbers F13 and F14, which have a combined area of 47.27 km2. Hellas Gold has been granted mining rights over these concessions until March 6, 2026. The Investment Agreement signed with the Hellenic Republic in 2021 and ratified by law, provides the further renewal for two consecutive periods of 25 years each, Hellas Gold has applied for the first 25-year renewal and approval is expected. Hellas Gold has ownership of a small portion of private land within the concessions.

In July 2011, the Ministry of Environment (MOE) formally approved the Environmental Impact Statement (EIS) submitted by Hellas Gold for the three Kassandra Mines mine sites, being Olympias, Skouries and Stratoni, which was subsequently amended in 2021, 2022 and 2023, is now valid until 2038 and as provided in Greek environmental legislation (law 4014/2011) is subject to an extension for 4 years, if Hellas Gold is certified with ISO 14001, or for 6 years if it is certified under the Eco-Management and Audit Scheme (EMAS).

For production to commence, the MOE required the submission of a technical study. A study was submitted to the MOE and approved in early 2012. The installation permit for what was termed the Phase II process plant was issued on March 22, 2016. Hellas Gold received the operating permit for the Phase II plant in September 2017, allowing commencement of commercial production operations. Also, in September 2017 Hellas Gold received an extension of the installation permit and an interim operating permit for the Kokkinolakkas Tailings Management Facility (TMF), as well as the delayed installation permit for the paste backfill plant.

Notifications for the Operation of the Olympias Paste Plant and Kokkinolakkas TMF were formally submitted in 2018 and remain in force in line with new legislation that replaced previous operating permit issuance procedures.

31

On February 5, 2021, Eldorado entered into an amended Investment Agreement with the Hellenic Republic to govern the further development, construction, and operation of the Kassandra Mines complex. The Agreement became legally effective on March 23, 2021 following ratification by the Hellenic Parliament and publication in the Greek Government Gazette. The Agreement is governed by Greek law. Its initial term continues to 2051 and may be extended by an additional 25 years subject to certain conditions.

The Investment Agreement includes a planned expansion of Olympias to 650 kilotonnes per annum (ktpa) of ore, from a 2023 throughput of 454 ktpa. On an annualized basis, the operation has demonstrated capability to achieve approximately 520 ktpa with its current configuration, considering highest monthly throughputs achieved. The Investment Agreement also outlines additional benefits to the region, including additional jobs, increased fiscal revenues and community development. The new EIA approved in 2023 includes the expansion of Olympias.

Based on current Greek legislation, royalties are applicable on active mining titles. The royalty is calculated on a sliding scale tied to metal prices and US$/€ exchange rates. At the price index selected for the Project evaluation, Hellas Gold would pay a royalty of approximately 3.30% on Au, 2.75% on Ag, 0.55% on Pb, and 1.65% on Zn revenues. As part of the terms of the Investment Agreement, the company pays an additional 10% of the royalty value until such time that a gold processing metallurgy plant would be constructed. The corporate income tax rate is set at 22%.

There are no other royalties, back-in rights, payments, or other agreements and encumbrances to which the Olympias property is subject. There are no known significant factors or risks that might affect access or title, or the right or ability to perform work on, the Olympias property, including permitting and environmental liabilities to which the project is subject.

History

Mining has occurred since ancient times in the area peaking during the time of Philip II of Macedon and Alexander the Great, in the period 350 to 300 BC with bulk ores extracted from the mine. Modern mining began in 1933 with an exploration shaft and drilling programs intermittently through to the 1960s. Operations began in 1970 and were suspended in 1995. In 2012, Eldorado acquired European Goldfields Mining (Netherlands) B.V. and, indirectly, a 95% interest in Hellas Gold, a wholly-owned subsidiary of European Goldfields, which held the concession for the project. In 2020, Eldorado purchased the remaining 5% ownership in Hellas Gold from Aktor, an unrelated third party.

Geological Setting, Mineralization and Deposit Types

The Western Tethyan orogenic belt in southeast Europe contains several major metallogenic provinces including the Serbo-Macedonian Metallogenic Province that hosts the Kassandra mining district. Crystalline basement within the district includes the upper Serbo-Macedonian Vertiskos Unit and the lower Kerdilion Unit exposed within the southern Rhodope metamorphic core complex.

The Olympias deposit is located 6 km north of the Stratoni fault within the Kerdilion unit. Replacement-style sulphide orebodies are hosted by marble interlayered within a sequence of quartzo-feldspathic biotite gneiss, amphibolite, and plagioclase microcline orthogneiss. The massive sulphide orebodies plunge shallowly to the southeast for over 1.8 km, subparallel to the orientation of F2 fold hinges and a locally developed L2 intersection lineation. The locations of the sulphide lenses, however, are largely controlled by strands of the ductile-brittle Kassandra fault and East fault and sub-horizontal shear zones that occur between the two faults.

Sulphide mineralogy of the Olympias deposit consists of coarse-grained, massive, and banded lenses dominated by variable amounts of sphalerite, galena, pyrite, arsenopyrite, chalcopyrite, and boulangerite. Gold occurs primarily in solid solution within arsenopyrite and pyrite.

Olympias is an example of a polymetallic carbonate replacement deposit. However, it is somewhat unusual due to the high gold content of the deposit. Key characteristics of this class of deposit include carbonate host rocks, massive sulphide mineralization, spatial and temporal relationship with magmatism, and zoned metal distribution.

32

Exploration

Eldorado has conducted limited exploration since 2012 as focus has been on improving definition of the known resource. Several geological studies, including surface mapping and hyperspectral analyses, have been carried out. In 2023, a surface induced polarization (IP) geophysical survey and a soil geochemical survey were conducted above and to the west and north of the deposit to identify possible future drilling targets.

Drilling and Sampling

In 2023, drilling activities at Olympias totalled 38,853 metres from 330 holes. This drilling included 24,516 metres of infill drilling from 240 holes, 9,136 metres of resource conversion drilling from 80 holes, 936 metres of resource addition drilling from 3 holes, 765 metres of geotechnical drilling from 6 holes, and one 500 metre exploration drill hole.

Drilling targeted high Au grade mineralization and confirmation and upgrade of the indicated and inferred resources that could be incorporated into short- and mid-term mine planning. The target areas were mainly on lower East where mineralization has potential to extend downward, recently discovered westward extension of Flats and West zone. The drilling was also testing hypothesized controls on mineralization. To date 448,762 m have been drilled (surface and underground diamond drilling) around the East, Flats and West ore zones in the drilling program.

Diamond drillholes are the sole source of subsurface geologic and grade data for the Olympias Mineral Resource estimation. The previous operator, TVX, drilled 764 drillholes for a total of 93,246 m. These drillholes are becoming less important as new information is acquired. Currently, holes are drilled by Eldorado using contractors drilling HQ or NQ-size (63.5 mm or 47.6 mm nominal core diameter). The average drillhole depth is approximately 100 m, as the holes are drilled from locations underground giving good intersection angles with the zones. A total of 2,860 drillholes for 309,822 m have been drilled on the property, of which 2,749 drillholes for 286,950 m were drilled by Eldorado since 2014 for the purposes of exploration, delineation, infill and mine services.

Core is delivered to secure core logging areas, and the core is logged in detail straight into a database using computer tablets. Lithology, alteration, structure, and mineralization data are collected; core recovery data are also measured. Core photos are routinely taken of all the core, both wet and dry, using a camera stand to ensure consistent photographs. Collar and downhole survey data are collected. Downhole surveys are taken using either a Devico Devigyro or Deviflex multishot instrument. Both of these instruments are calibrated annually. A dataset of measured bulk densities from over 900 mineralized samples is used to inform the resource block model.

Sampling, Analysis and Data Verification

Sampling of the core is carried out on approximately 1 m intervals or to geological contacts. The core is sawn using an automated core saw and half is bagged for dispatch, with the remainder being placed in the core box for storage. Drill core samples are routinely sent to the ALS Global (ALS) facility in Romania. They are bagged and packed in large sealed wooden bins before being trucked to ALS. The sample rejects are returned to the mine site in the same bins. The samples are prepared for assaying at the ALS facility.

All samples were assayed for gold by 30 g fire assay with an AAS finish, with Au values above 10 ppm determined by a gravimetric finish. Multi-element determination was carried out by inductively coupled plasma mass spectrometry (ICP-MS) analysis and / or inductively coupled plasma emission spectroscopy (ICP-ES) analysis.

A comprehensive QA/QC program is in place incorporating CRM, blanks, and duplicate samples. CRMs are used that contain all of the payable metals at Olympias (Au, Ag, Pb, Zn). Blank samples are used to monitor contamination during the sample preparation and assay processes.

In the opinion of the Qualified Person, the sampling, sample preparation, security, and analytical procedures, as demonstrated by the QA/QC results, show that the Olympias mine’s assay database is adequate for Mineral Resource estimation.

All of the Qualified Persons carried out verification of data pertaining to the sections for which they are responsible.

33

Mineral Processing and Metallurgical Testing

Metallurgical testwork was carried out ahead of the re-start of the Olympias operation with the current process flowsheet in 2017.

In 2015, metallurgical testwork and mineralogical investigations were carried out on ore samples from the Olympias deposit. The main sulphide minerals in these samples were found to be galena, sphalerite, pyrite and arsenopyrite. Other than quartz, all other minerals can be considered minor. The liberation of all sulphide minerals was excellent at a grind of 120 µm P80. Flotation of galena, sphalerite and pyrite / arsenopyrite in a sequential flowsheet was found to be effective at producing lead / silver, zinc, and gold concentrates.

Lead flotation was shown to be effective with collector Aerophine 3418A, with lime, zinc sulfate and sodium cyanide added as depressants. Copper activation and zinc flotation were found to be optimum at pH 11.8 with SIPX as the collector. Flotation of pyrite and arsenopyrite was effective at pH 6.0 controlled with sulfuric acid and SIPX as the collector. Some challenges were observed in rejecting arsenic and antimony from the lead concentrate in some of the testwork although the presence of these deleterious elements is variable across the deposit.

Tests confirmed good settling-thickening characteristics for the concentrates and tailings samples. Vacuum filtration of the tails underflow sample showed high throughput and low residual cake moisture. Pressure filtration on concentrate underflow samples indicated high throughput and low residual moisture.

Additional variability testwork was carried out in 2021, with composites and blends produced from the East, West, and Flats area of the deposit. Comminution results from this testwork confirmed that future ores would continue to be considered as soft in terms of grindability. Flotation testwork identified that the proportion of lead hosted within galena, boulangerite, or bournonite had a direct impact on the amount of antimony recovered to the final lead concentrate.

Mineral Resources and Reserves Estimates

Mineral Resource estimates for the Olympias mine were made from a 3D block model utilizing MineSight (MinePlan) 3D software. Project limits, in UTM coordinates, are 478105 to 479700 East, 4491165 to 4493480 North and -800 to +60 m elevation. Block size for the project was 5 m east x 5 m west x 5 m high.

A grade-based discriminant was developed to allow for more consistent interpretations to be made. This was accomplished by creating a simplistic value formula based on the logic of a Net Smelter Return (NSR) formula that used a combination of metal prices and metal recoveries to act as weighting factors against each metal. This metric, a dollar value, proved to be an excellent surrogate for a comprehensive equivalent grade. Inspection of these resource defining values (RDV) showed that, for the parameters used, a value of $50 best defined what one would classify as likely economically mineralized zones.

For the Olympias modelling, the deposit was divided into three zones: East, West, and Flats. Within each of these zones, modelling domains were created using the $50 RDV. Assays and composite samples were tagged by these domain shapes ahead of data analysis and grade interpolation. The assays were top capped prior to compositing and were composited into 1 m composites within the domains.

Grade estimates for Au, Ag, As, Pb, Zn, and Fe were interpolated using ordinary kriging (OK). Nearest–neighbor (NN) grades were also interpolated as a declustered distribution to validate the estimation method. Note that bulk density and sulfur were calculated as a function of the estimated block grades.

Areas of previous mining are located in the East and West Zones, and these were removed from the initial Mineral Resource estimate. The metal models were validated by visual inspection, checks for global bias and local trends and for appropriate levels of smoothing (change-of-support checks).

The Mineral Resource was classified using the CIM Definition Standards for Mineral Resources and Mineral Reserves (May 10, 2014) that are incorporated by reference into NI 43-101. The mineralization of the mine satisfies sufficient criteria to be classified into Measured, Indicated, and Inferred Mineral Resource categories. Olympias mine Mineral Resources, as of September 30, 2023, are shown in Table 1‑1. The Olympias mine Mineral Resources are reported within 3D constraining volumes whose design was guided by the reporting cut-off value of NSR $125, contiguous areas of mineralization and mineability. Only material internal to these volumes was eligible for reporting, to satisfy “reasonable prospects for eventual economic extraction”.

•Tonnages of mined out blocks and sterilized areas were depleted from the model.

•Mineral Resources were constrained by 3D volumes whose design was guided by the reporting cut-off grade of $125 NSR, contiguous areas of mineralization and mineability. Only material internal to these volumes was eligible for reporting.

•The NSR value is based on a combination of metal price and individual metal recoveries which are variable throughout the deposit, and smelter considerations.

•Prices used to define potentially mineable shapes are as follows, gold $1,800/oz, silver $24/oz, zinc $2,600/t, lead $2,400/t.

•The drillhole database was closed at end-April 2023.

•The numbers may not compute exactly due to rounding.

•Measured Mineral Resources in this table include 2.8 kt of stockpiled ore at the end of September 2023.

The Mineral Reserve estimates were classified using the CIM Definition Standards for Mineral Resources and Mineral Reserves (May 10, 2014) that are incorporated by reference into NI 43-101. All design and scheduling have been completed using the Mineral Resource model and estimate. Only Measured and Indicated Mineral Resources have been used for Mineral Reserve estimation. The estimation assumes that the mining method employed at the mine will be Drift-and-Fill (DAF).

The cut-off values supporting the estimation of underground Mineral Reserves were developed in 2023 from the 2023 budget and future projected operating and sustaining capital costs at a steady-state target production rate of 650 ktpa. The cost assessment indicated that NSR values of $218/t for DAF mining would adequately cover all site operating and sustaining capital costs. The DAF costs were used to create potentially mineable stope shapes from the NSR block model.

In the evaluation of underground Mineral Reserves, modifying factors were applied to the tonnages and grades of all mining shapes to account for dilution and ore losses. In the DAF stopes, a mining dilution factor of 15% and a mining recovery of 95% were used to estimate Mineral Reserves.

The Mineral Reserve estimate is summarized in Table 1‑2 and has an effective date of September 30, 2023.

Mineral Resource and Mineral Reserve estimates for Olympias may be affected by technical and other relevant factors which are more specifically described in our "Risk Factors" section.

Mining Operations

The Olympias mine is an underground mining operation extracting ore from three main zones: East, West and Flats; the Remnants are a sub-zone of the West Zone. Total mined material at Olympias will ramp up from an expected 810 ktpa in 2024 to an average of 990 ktpa over the 2025 – 2031 period, following by a decline in total mined material averaging 720 ktpa over the 2025 – 2032 period. Total mined material includes ore, operating waste, and capitalized waste mined. Annual mined waste quantities follow a general decreasing trend from 2025 onward. Correspondingly, ore production will increase from an expected 500 ktpa in 2024 to an average of 645 ktpa over the 2025 – 2035 period.

The rock mass conditions at the Olympias mine are highly variable due to complex geology and presence of fault structures. Ground support classes have been implemented based on a range of Q values for ore and waste rock development. Ground support elements used at Olympias include wire mesh, shotcrete, rebar, split sets, Swellex, self-drilling anchors, and cable bolts of varying lengths. Field observations indicate that underground openings are stable and ground support application is generally adequate, with no unsecured ground being noted and support performance apparently good.

DAF at Olympias commences once the decline reaches the footwall drive or Level access elevation of the orebody, usually midway along its strike length. DAF is an overhand mining method. The stope sequence begins with the lowest 5.0 m high lift. Then each subsequent lift requires the back of the level access to be slashed down (‘take-down-back’ or TDB) to reach the next lift. There are four lifts between levels for a total rise of 20 m from each access.

All stopes are filled with backfill after excavation. Currently a combination of cemented aggregate fill (CAF), paste fill and waste rock fill is used. The paste fill system has been designed to produce 42 m3/h of paste, which will meet all future backfill requirements at 650 ktpa production with 70% utilization. CAF and waste rock is delivered to stopes by truck and pushed into place with loaders. Paste is delivered with positive displacement pumps via drillholes and pipes.

There are two declines currently in use, one accessing the West Zone that will be extended to the base of the West Zone. The second decline accesses the East Zone that will be extended to the base of the East Zone and will also connect to the upper Flats. There are multiple cross-over drifts between these two declines above the Flats. Both declines are currently being extended to the bottom of the West and East Zones. The third and final main decline will be developed for the Flats from -370 masl to the base of the Flats.

Both ore and waste are hauled to surface utilizing 40 t trucks on the existing and expanding declines. This will continue to be the case after the production increases to a steady state value of 650 ktpa.

The total number of personnel currently working at the mine is 347. The mine operates three shifts a day, 21 shifts per week.There are currently 20 large pieces of mobile mining equipment on site: three jumbos, four bolters, five trucks, eight loaders. In addition, there are sixteen utility vehicles, two transmixers and three shotcrete sprayers. To achieve the production increase to 650 ktpa, additional primary equipment will be added to the fleet, including jumbos, bolters, trucks, and loaders.

The ventilation design is based on an exhausting system configuration with the main fans ultimately located on the surface at the single exhaust raise. At present, fresh air for Olympias is supplied from the +59 Portal, +70 Portal, Shaft, and Fires area. Exhaust is through the main exhaust raise at -173 level. The recently installed ventilation system was upgraded in 2023, with the large surface exhaust fans located at the main exhaust raise collar, ensuring the required airflow for the mine of 420 m3/s is attained.

Olympias mine currently uses bulk emulsion product for all blasting practices in the underground mine. There is no existing magazine on the property and explosives are delivered to site daily by the supplier. However, bulk emulsion matrix is stored in large bays underground as it is not considered an explosive until it sensitizes inside the mobile emulsion production unit underground – usually done at the face during charging activities. The construction of a new underground magazine is ongoing, with excavations having been completed and installation of shelving is planned to be completed in the near future. By the end of Q2 2024, Olympias plans to commission an underground maintenance workshop that will be able to repair heavy duty machinery right underground saving tramming time of the equipment.

36

As an operating mine, infrastructure is well developed, with existing process water, compressed air, electrical distribution, and dewatering systems. For the 650 ktpa expansion, a new compressor, dewatering station, and underground shop are being installed. These activities are currently in progress.

Processing and Recovery Operations

The Olympias lead-zinc-gold-silver process plant has been developed in phases:

•Phase I involved the recommissioning of the plant after prolonged inactivity and processing of the existing tailings. Phase I commenced in 2013 and was completed on commissioning of Phase II in 2016.

•Phase II was commissioned in mid-2017 and is currently in operation. It included refurbishment and upgrading of all the process facilities to process 400 – 440 ktpa of ore. The Phase II process facility consists of comminution, flotation and filtering to produce three saleable concentrates: lead / silver (lead), zinc, and arsenopyrite / pyrite gold (gold). All concentrates are sold to worldwide markets. Tailings are used for underground backfill via the on-surface paste plant or trucked to the Kokkinolakkas tailings management facility.

•The expansion project involves upgrading of the existing Olympias process plant to handle a mine feed rate of 650 ktpa of ore, an increase of approximately 25% considering the newly established technical limits of the existing process plant. Capital expenditure for the expansion of the plant is scheduled from 2023 to 2025, and the 650 ktpa throughput is planned to commence in 2026.

The processing facility incorporates the following process unit operations:

•Three-stage crushing.

•Single-stage ball milling in closed circuit with hydrocyclones.

•Nearly all hydrocyclone underflow is fed to flash flotation.

•Lead flotation consists of rougher, scavenger, regrinding, and three stages of cleaning.

•Zinc flotation consists of rougher, scavenger, regrinding, and three stages of cleaning.

•Gold-pyrite flotation utilizes rougher, scavenger, and a single stage of cleaning.

•Concentrate thickening, filtration, and packaging.

•Tailings thickening and filtration.

•Tailings paste backfill - mixing and pumping.

•Reagent mixing, storage, and distribution.

•Water and air services.

The Olympias plant produces three concentrates: an arsenopyrite / pyrite concentrate containing gold, a lead concentrate that also contains silver and gold, and a zinc concentrate that also contains gold. The Company has negotiated multiple concentrate sales contracts with commodity traders, blenders, and smelters for concentrates from Olympias. Agreements with several customers in various countries are currently in place. Production data on current ore and metallurgical testwork on future ores support the throughput and recovery assumptions of base and precious metals to the three concentrate products.

Infrastructure, Permitting and Compliance Activities

As an operating mine, current infrastructure is robust and complete. The mine has access to the main highway system in Greece via paved roads to the mine site. Local services are provided via the towns of Olympiada and Stratoni, with additional services available through Thessaloniki.

A port facility located at Stratoni, 9 km from the Olympias process plant (26 km by paved road) is owned by Hellas Gold. Currently lead, zinc and arsenopyrite concentrates are shipped via the port facility. Lead and arsenopyrite concentrate may also be bagged at the process plant and shipped by truck to the port at Thessaloniki.

Water is supplied by surface facility contact water run-off and from underground mine dewatering. A series of three settling ponds, with a fourth as a spare, is used to remove suspended solids. This water is pumped to a raw water tank next to the clean water and process water tanks. Excess water from mine dewatering is treated in the surface water treatment plant. Process water is reclaimed from the tailings thickening and filtration circuit and backfill clarifier overflow. A minimum amount of make-up water is supplied from the raw water tank.

Waste from the underground mine is brought to surface and hauled to the Kokkinolakkas Tailings Management Facility (KTMF). Some waste rock is stored temporarily underground and is used to backfill voids underground left from the stope mining, saving on transportation cost as well as cost of paste fill.

Thickened tailings are pumped to the paste plant. If thickened tailings production exceeds the maximum capacity of the paste plant, excess thickened tailings can be pumped to one of two tailings pressure filters

37

located adjacent to the process plant. Filtered tailings are then trucked to the paste plant for additional feed into the plant when required.

Excess thickened tails are pumped to a tailings filter to produce a cake with a moisture content of 13%, which is then trucked to the KTMF for dry stacking. This facility is located 8.5 km south of Olympias (23 km by public paved road). In addition to mine tailings from the Olympias mining operations, tailings from historical mining activities at Olympias are also being hauled to the KTMF. It is designed to safely manage approximately 10.5 Mm3 of mine waste at an average dry density of 1.6 t/m3.

Current power to site consists of a 150kV transmission line from the national grid feeding a new 150kV to 20kV, 25MVA substation, which has sufficient rated capacity to meet all anticipated increases in mine load. Backup power consists of 3,700 kW of diesel generation in multiple distributed generators.

Water for the mine is obtained from underground dewatering, after treatment. Excess water from underground is discharged into the Mavrolakkas stream after settling and treatment to meet discharge standards. Currently, the capacity to handle 400 m3/hr was available; this has been increased to 650 m3/hr, which is expected to be sufficient for the mine life. Service water is supplied via a local borehole in the regional aquifer.

Existing surface facilities consist of a surface workshop, administration building, dry, shaft, and fuel storage (60,000 litres capacity). The workshop and fuel storage will be adequate for the production increase. The shaft is used for inspection of a legacy pump station only and there are plans to rehabilitate the shaft as required in the future.

Current power to site consists of a 20 kV 10 mVA pole line from the PPC grid. To facilitate the production increase, a new pole line at 150 kV 25 mVA, along with a new substation was completed in 2023. Backup power consists of 4,920 kW of diesel generation in multiple distributed generators. An additional 2,500 kW of generated power will be added for the production increase.

The EIS for the Kassandra Mines project includes an area of 26,400 ha in northeastern Halkidiki (Macedonia Region). Kassandra Mines includes the Skouries, Olympias and Stratoni sites. No significant impact is expected on the landscape, geological environment, atmosphere, or water resources in the area. The overall impacts to date have been positive to the environment, as legacy tailings and concentrate storage are in the process of being removed to the KTMF, and the associated areas rehabilitated. Kassandra Mines, as a whole provides significant economic and social impacts for the Halkidiki Prefecture, including:

•A significant contribution is made to the national economy.

•Significant infrastructure is constructed and equipped by local companies.

•Service industries in the local economy expand.

•Employment of a large skilled workforce.

After the completion of all operations at the Kassandra Mines, the project areas will be rehabilitated according to appropriate and approved land uses. All structures are to be removed or left in a state that they do not pose a risk to the environment or public. The environment will be returned to a state of a self-sustaining ecosystem and safe and stable biological conditions will be re-created.

Olympias Project has received and maintained all permits required to operate within Greece. Discussions are regularly held with the local communities and there are no ongoing negotiations which would materially affect the Project or operations. There are no known environmental impacts that would limit the ability to extract the Mineral Resources or Mineral Reserves.

Capital and Operating Costs

The Project has been on a continuous improvement program in all aspects of the operation to achieve a throughput of 650 ktpa. Capital costs include process plant upgrades and continuing mine development into new zones. Capital is also allocated for infrastructure to support the Project including ancillaries and expanding water management systems, indirects including EPCM costs to support capital projects, owners’ costs, continuing exploration, and contingencies; costs are summarized in Table 1‑3

1 As we have issued AISC/oz guidance by site in 2024, in addition to continuing total cash cost/oz guidance, we have previously announced that we will cease reporting of cash operating cost/oz in Q1 2024. The table above therefore reflects historic and forecasted reporting metrics, which will not be directly comparable.

39

In 2024, Olympias is expected to mine approximately 480,000 to 510,000 tonnes of ore at an average grade of 8.0 to 9.0 g/t of gold, 120 to 130 g/t of silver, 3.8 to 4.3% lead and 4.2 to 4.7% zinc. Payable production is expected to be 75,000 to 85,000 ounces of gold, 1.5 to 1.7 million ounces of silver, 13,000 to 16,000 tonnes of lead metal and 12,000 to 15,000 tonnes of zinc metal. Cash operating costs per ounce in 2024 are expected to be lower year-over-year due to increased production and throughput and higher by-product credits for silver, lead and zinc production.

Planned 2024 sustaining capital expenditures of $28 to $33 million include underground mine development and management of the Kokkinolakas tailings management facility. Planned 2024 growth capital of $14 to $18 million is primarily focused around mill expansion to support ramp-up to 650 ktpa and upgrading of ancillary facilities.

Property Description, Location and Access

The property is located within the Kassandra Mines complex, located on the Halkidiki Peninsula of northern Greece. The complex is located approximately 100 kilometres (km) east of Thessaloniki and comprises a group of mining and exploration concessions covering 317 squared kilometres (km2), of which the property is part. The properties within the complex include the Olympias Mine currently in production, Stratoni Mine on care and maintenance, and the Skouries copper-gold porphyry deposit under development.

The Skouries Project is a copper-gold porphyry deposit to be mined using a combination of conventional open pit and underground mining techniques. The mineral processing facilities will produce a gold-copper concentrate. The property is situated at an elevation range of 350 metres above sea level (“masl”) to 620 masl near the village of Megali Panagia in the prefecture of Halkidiki, northern Greece. It is approximately 7.2 km from the road connecting the villages of Megali Panagia and Palaiochori. The area is centred on co-ordinates 4745300 E and 4481400 N of the Greek Reference System EGSA ‘87, at approximately Latitude 40°29’ and Longitude 23°42’. The location is classified according to Greek Seismic Code NEAK 2000 (modified in 2003) as Zone II. The Property consists of concession numbers OP03, OP04, OP20, OP38, OP39, OP40, OP48, and OP57, which have a combined area of 55.1 km2. Hellas Gold has been granted mining rights over these concessions until March 6, 2026. The Investment Agreement signed with the Hellenic Republic in 2021 and ratified by law 4785/2021, provides the further renewal for two consecutive periods of 25 years each; Hellas Gold has applied for the first 25-year renewal and approval is expected. Hellas Gold owns a small portion of private land within the concessions, is granted use of forestry land and is in negotiation for the remaining 0.3% of the total area required.

The Environmental Impact Study (“EIS”) for the Kassandra Mines Mineral Deposits Project includes an area of 26,400 hectares (ha), in northeastern Halkidiki (Macedonia Region). The Skouries Project covers approximately 250 ha of the Kassandra Complex.The EIS considers the potential impact on the local and regional environment as it relates to:

•Open pit and underground workings.

•Tailings impoundment.

•Process plant.

•Infrastructure necessary for the Project operation.

History

There is a long history of mining in the region dating back to 350 to 300 BC and continuing through the Roman, Byzantine and Ottoman periods. There is limited historic development at the Skouries site. In modern times, the Skouries deposit was initially drilled by Nippon Mining and Placer Development (“Placer”) during the 1960s. Placer also carried out limited underground development from an adit. The deposit was subsequently drilled in the 1970s by the Hellenic Fertiliser Company. TVX Gold Incorporated (“TVX”) began a drilling program in August 1996 to confirm the deposit and to explore it at depth. A subsequent infill drilling program was conducted in 1997 with the objective of improving the evaluation of Indicated Mineral Resources in the deeper high-grade zone. European Goldfields Limited acquired the Property in 2004, audited the TVX program and prepared a pre-feasibility study in 2006. The pre-feasibility study reflected an open pit operation followed by an underground mine using sub-level caving (“SLC”) underground mining methods at a production rate of 6.5 million tonnes per annum (“Mtpa”).

Geological Setting, Mineralization and Deposit Types

The Skouries deposit is centred on a small porphyry stock that has a surface expression of approximately

200 metres (m) in diameter. Skouries is typical of a copper-gold pencil porphyry. Mineralization occurs in

stockwork veins, veinlets and disseminated styles typical of a porphyry, which has a sub-vertical, pipe-like

shape. Mineralization has been tested to a depth of 920 m from surface and the results show the orebody

is open at depth. Potassic alteration and copper-gold mineralization also extend into the country rock;

approximately two thirds of the Measured and Indicated Resources are hosted outside of the porphyry,

with about a 50:50 split in gold-equivalent ounces.

Drilling and Sampling

Diamond drillholes are the sole source of subsurface geologic and grade data for the Skouries Project. Resource delineation drilling was carried out in two major campaigns: in 1996 – 98 by then owner TVX and in 2012 to 2013 by Eldorado. TVX drilled a total 72,232 m of core in 121 drillholes using NQ (47.6 millimetres (mm)) diameter core. Holes reached a maximum depth of 1,013 m. Eldorado conducted two drill campaigns on the Skouries Project in 2012 and 2013: a 34-hole, infill drilling program comprising 6,922 m and a 10-hole, 6,617 m confirmation program. The confirmation program was completed to test the core of the main mineralized portion of the deposit to compensate for the lack of a drillcore record from the earlier TVX campaign. These confirmation drillholes confirmed the earlier results and are not included in the current Mineral Resource estimation.

The majority of the core samples for the Skouries Project originated from the 1996 – 98 drill campaign by TVX. Eldorado has reviewed the TVX studies and QA/QC procedures and agrees with the conclusions that the drill data are acceptable to be used for Mineral Resource estimation. The Qualified Person concurs with this conclusion on the pre-Eldorado data having reviewed the reports. The background and QA/QC results of the Eldorado work were reviewed in detail under the Qualified Person supervision, replotted and deemed suitable for estimation purposes. Confidence in the data is also provided by the results of Eldorado’s confirmation drill program.

Metallurgical Testwork

Metallurgical testwork and studies were performed by Lakefield Research, Canada on composites selected from core samples of the major rock types, covering mineralogy, grinding and flotation. This testing was carried out to support the original 2007 design completed by Aker Kvaerner. Based upon this information, the criteria for process plant and infrastructure design were established.

Additional testwork was completed by Outotec in 2007, mostly at its laboratory in Pori, Finland, to give additional design confidence. This included flash flotation, gravity gold recovery, concentrate settling and filtration.

Further supplementary testwork was undertaken by FLS Knelson in 2013 on gravity gold recovery and by Wardell Armstrong in 2015 on flotation concentrate. Solvay (formerly Cytec), in 2016, and Bureau Veritas Commodities Canada, in 2017, worked on selective flotation of copper from pyrite-rich ore. In 2014, Orway Mineral Consultants (OMC) reviewed the testwork conducted by Aker Kvaerner to design the Skouries grinding circuit and conducted comminution circuit modelling studies using circuit simulations.

Mineral Resources and Mineral Reserves

The Mineral Resource estimate for the Skouries deposit was developed using assays and data from surface diamond drillholes. The estimate was made from a three-dimensional (3D) block model based on initial outlines derived by a method of probability assisted constrained kriging (“PACK”). The estimation,

41

for both gold and copper, was within what is termed the 0.1% Cu PACK shell. The block size for the Skouries model was selected based on mining selectivity considerations and is 5 m x 5 m x 10 m. Copper and gold grades are highest in the porphyry. The gold to copper ratios are also markedly different between the intrusive and non-intrusive units. Generally, the coefficient of variance (“CV”) values for copper in all units is relatively low reflecting the porphyry style mineralization of the deposit. Gold CV values are higher, especially in the schist unit, reflecting some influence by local extreme grades. These were mitigated by a gold grade cap equal to 20 grams per tonne (g/t), applied to the assay data prior to compositing.

The assays were composited into 4 m fixed-length downhole composites and were back-tagged by the mineralized shell and lithology units. The compositing process and subsequent back-tagging was reviewed and found to have performed as expected. Modelling consisted of grade interpolation by ordinary kriging. A two-pass approach was instituted for interpolation. Nearest-neighbour grades were also interpolated for validation purposes.

As part of this reporting, the Qualified Person reviewed and validated the model by performing visual, statistical, and graphical checks in the form of a series of swath plots and checking reporting. On this basis, the Qualified Person is comfortable with the validity of the model.

The Mineral Resources of the Skouries deposit were classified using logic consistent with the CIM Definitions Standards. The mineralization of the Skouries deposit satisfies sufficient criteria to allow classification into Measured, Indicated, and Inferred Mineral Resource categories.

Reasonable grade and geologic continuity are demonstrated over most of the Skouries deposit, which is drilled generally on 40 m to 80 m, spaced sections. A two-hole rule was used where blocks containing an estimate resulting from two or more samples, all within 80 m and from different holes, were classified as Indicated Mineral Resources. For Measured Mineral Resource classification, a three-hole rule was applied where blocks contained an estimate resulting from three or more samples, all within 50 m and from different holes.

All remaining model blocks containing a gold grade estimate were classified as Inferred Mineral Resources.

The demonstration of Reasonable Prospects for Eventual Economic Extraction (“RPEEE”) was handled for both the open pit and underground portions of the deposit by creating potentially mineable shapes. In each case a long-term gold price of US$1,800/oz and copper price of US$3.50/lb were selected for the determination of Mineral Resource cut-off grades and pit shell. A gold equivalent (“AuEq”) calculation was used to combine the value of the two payable metals. The cut-offs used for defining the shapes were 0.3 g/t AuEq for open pit and 0.7 g/t AuEq for underground where AuEq is determined by AuEq = Au g/t + 1.25* Cu%. The parameters for cut-off grade calculations are listed in Table 1-1.

Table 1-1: Economic Parameters for RPEEE Evaluation

Description	Units	Open pit	Underground
Gold price	US$/oz	1,800	1,800
Copper price	US$/lb	3.50	3.50
Mining cost	US$/t processed	4.10	19.50
Process cost	US$/t processed	8.48	8.48
Filter plant cost	US$/t processed	2.13	2.13
IEWMF and water management	US$/t processed	0.13	0.13
G&A	US$/t processed	2.78	2.78
Overall costs	US$/t processed	17.62	33.02
Mill Au recovery	%	86.7	86.7
Mill Cu recovery	%	91.5	91.5
Cut-off used	AuEq g/t	0.3	0.7

The potentially mineable shapes representing volumes that have a reasonable expectation of being mined were determined as follows. Volumes that lie within both the 0.1% Cu PACK shell and the open pit shell and are predominantly above a cut-off grade of 0.3 g/t AuEq are assigned to the open pit reporting shape. Volumes that lie outside the open pit shell and lie within the 0.1% Cu PACK shell and are predominantly above a 0.7 g/t AuEq cut-off grade are assigned to the underground resource reporting shape. Volumes within both the open pit and underground resource reporting shapes are reported in their entirety; this includes some isolated blocks that are below the assigned cut-off, but that lie within the

42

volumes deemed to be reasonably mineable. Similarly, isolated blocks that are above the cut-off grades, but that lie outside of the expected mineable volumes are omitted from the Mineral Resource estimate.

The Skouries Mineral Resources as of September 30, 2023 are shown in Table 1-2. The economic parameters and AuEq factors used are defined in the footnotes. The Mineral Reserves and metal prices used are unchanged from the 2021 Feasibility Study but were most recently reported as part of Eldorado’s Annual MRMR disclosure effective September 30, 2023.

The Qualified Person has validated the Mineral Resources. The data, methodology and analysis described in this report are considered sufficient for reporting Mineral Resources. There is no difference between the Mineral Resources reported in September 2020 and September 2023 and both statements are made on the same basis. There has been no production from the deposit, hence no depletion from the block model.

The Mineral Reserves at Skouries comprise an open pit and an underground component. Block model items transferred from the geology model for mine planning included estimated grades for copper and gold as well as Mineral Resource classification. Measured and Indicated Mineral Resources have been used to define the pit limits and for reporting of Mineral Reserves for scheduling. Inferred Mineral Resources were not used in the determination of Mineral Reserves.

The open pit optimization was carried out using MineSight (MinePlan) mine planning software. The Skouries open pit is constrained by the existing EIS boundary on surface and a potential underground mining crown pillar, which limits the pit depth to 420 masl. In addition to the physical boundary constraints, the open pit design and overall size is also affected by a requirement to provide construction materials for the IEWMF (as defined below), which contains dry stacked tailings.

43

The Mineral Reserves for the deposit were estimated using a gold price of US$1,300/oz and copper price of US$2.75/lb. The open pit Mineral Reserves are reported using a US$10.60/t NSR cut-off value. The open pit combined Proven and Probable Mineral Reserves are 59.6 million tonnes (Mt) with an average grade of 0.57 g/t Au and 0.40% Cu.

The underground contribution to Mineral Reserves has been evaluated at a diluted NSR cut-off of US$33.33/t, incorporating unplanned diluting material of 5% for porphyry stopes and 5.5% for schist stopes that is assumed to carry no metal value, and assuming an overall mining recovery of 95%. The Mineral Reserves for the underground deposit have been estimated to be 87.5 Mt with an average grade of 0.90 g/t Au and 0.58% Cu.

The combined Mineral Reserves for the Skouries Project, as of September 30, 2023, are stated in Table 1-3. These represent the sum of the open pit and the underground Mineral Reserves. The cut-off values for the Mineral Reserves are NSR based with US$10.60/t used in the open pit portion and US$33.33/t for the underground estimate. The Mineral Reserves and metal prices used are unchanged from the 2021 Feasibility Study but were most recently reported as part of Eldorado’s Annual MRMR disclosure, effective September 30, 2023.

Mining Operations and Methods

Open pit mining is expected to be by conventional truck-shovel operation, with an ore production rate of approximately 5.5 Mtpa, at a waste to ore stripping ratio of approximately 0.90:1. The mining sequence will consist of drilling, blasting, loading, and hauling of ore and waste materials for processing and waste disposal. Based on the modelled rock types, approximately 17% of the mined material is amenable to free digging; this material will not be blasted. Direct feed ore from the open pit will be hauled to the Skouries processing plant. A portion of low-grade ore (LGO) will be hauled directly to the plant, and an additional portion will be hauled to the low-grade ore stockpile (LGOS) where it will be re-handled during Phase 2 of the Project.

Waste material is expected to be hauled directly to one of the material management structures within the Integrated Extractive Waste Management Facility (IEWMF). The structures internal to the IEWMF are the LGO embankment, J5, Capping Rock Dump1, Cofferdam Karatza Lakkos (KL) Embankment, and South Diversion Channel. Drilling operations will be carried out continuously as part of the normal mining operation. Once full mine production is reached, drilling and blasting of approximately 1 Mt (dry) per month will be required to maintain projected production levels.

The primary haul roads are designed at 25 m width, based on a 90 tonne (t) haul truck. Other haul roads, to be used by contractor trucks, are designed for 55 t articulated haul trucks with an overall roadway width of 15 m.

The number of haulage units was determined by calculating cycle times in Haulage© from MinePlan© using annual haul cycle profiles from MinePlan©. Haulage calculations were carried out based on the designated 90 t and smaller 55 t trucks. A maximum truck speed limit of 50 km/h was set for flat or

44

inclined roads, reducing to 15 km/h near shovel and dump points and 15 km/h around switchback corners. On the downhill segments, speeds were limited to a maximum of 25 km/h. A tonnage factor for each material type was used to determine actual payload versus theoretical maximum payload for each truck class. These factors were based on experience from operations at other sites.

The open pit mine production schedule has been developed using a planned average annual ore production rate of 5.5 Mtpa. The actual yearly rate varies according to the ore production ramp-up schedule for the underground Phase 1, which will offset open pit ore. An open pit mining operation of 350 days per year consisting of three, eight-hour shifts operating 7 days a week is envisaged. The Skouries orebody that extends below the bottom of the open pit is amenable to a bulk underground mining method and has been evaluated under several different design approaches since the late 1990s, including block caving, sublevel cave (SLC), and sublevel long hole open stope (SLOS). SLOS has been confirmed as the most appropriate underground mining method for a number of reasons including:

•The geo-technical stability of the final reclaimed land after closure of the Project.

•The minimization of land-take needed for the surface tailings.

•The ability to backfill the depleted open pit.

The majority of the stoping is considered to take place in reasonable quality rock mass. The stope stability assessment has indicated that, for stoping in the porphyry, a 60 m sub-level interval (60 m stope height plus 5 m top drive development) can largely be viable without significantly compromising stope wall stability if the length of the stope does not exceed 30 m. Of the stopes that will be extracted in the schist, only half of these excavations will expose schist in the stope sidewalls as secondary stopes will expose the paste backfill within the primaries.

Stope back stability assessments were conducted using the NGI-Q stability graph as well as the stability graph method to determine appropriate stoping spans. Stope span has been limited to 15 m. Thus, the standard stope dimensions were set to 65 m high x 30 m long x 15 m wide in porphyry stopes, 65 m high x 20 m long x 15 m wide for primary stope design in schist material, and 65 m high x 30 m long x 15 m wide for secondary stope design in schist material.

All levels in both phases have similar designs. Peripheral development (Ring-drives) will provide access to all sides of the orebody and terminate at return air raise (RAR) locations. Ore drives for stope extraction will traverse the orebody east to west on 15 m centres, developed incrementally to meet the production schedule and mining sequence. Both ramps are planned to be used to haul ore, with the orebody divided into East and West in order to maintain a stope extraction sequence from the centre out. The underground portion of the Skouries Project will begin from the existing ramp from the surface to 385 masl. The ramp is currently developed to 35 m above the first production level, 350L. Mining will proceed to the 350L to establish major infrastructure and services. The 350L will serve as the mucking horizon for two test stopes, which are situated in the Crown Pillar and within the mining limits to enable a mineralized and accurate representation of the mining to be completed in Phase 1.

For Years -3 through to Year 2, underground mining efforts will focus on developing the access ramp and further establishing the levels and services for production, while also developing a second portal and ramp to the surface. In Year 4, the development is expected to begin in preparation for Phase 2. This development will entail the dual ramp systems to -130L, the major underground workshop, fuel bay and excavations for the materials handling systems.

Underground mining will be by conventional underground mining techniques. The mining sequence will consist of drilling, blasting, loading, and hauling of ore and waste materials. During Phase 1, ore will be hauled to the surface crusher by truck. During Phase 2 ore will be hoisted to surface by a shaft. In Year 4, the shaft headframe construction will commence, and shaft excavation will begin in Year 6. Excavation of the shaft will continue through Year 8, with the entire materials handling system projected for completion six months prior to the beginning of Phase 2 in Year 10.

The design of the Skouries mine includes provision for remote mining technology (RMT), which has an impact on the cycle times of stopes and the productivity of equipment. This technology includes tele-remote operation of mechanized equipment by an operator located on surface or in a remote area of the underground mine. RMT is considered a best available technology, and Skouries mine is uniquely positioned to benefit from the improvements in mining process due to the simple repetitive nature of the design and the availability of highly skilled technical workers.

Recovery Methods

For the first nine years of operation, the ore will be extracted from the open pit mine as well as from the underground mine for a total mill feed rate of 8.0 Mtpa. From the tenth year of operation until the depletion of Mineral Reserves, the plant will process ore extracted from the underground mine at an average of

45

around 6.5 Mtpa tailing off in Years 19 and 20. During years 10 to 14, previously stockpiled oxide ore will be re-handled to maintain mill feed at 8.0 Mtpa.

The plant will process the copper / gold ore at a projected LOM average head grade of 0.50% copper and 0.77 g/t gold. Anticipated LOM average payable recoveries are 87% for copper and 81% for gold. The mill will produce a flotation concentrate that contains an average of 26% copper and 27 g/t gold. Metallurgical tests have shown that the ore contains a small amount of palladium (Pd), which will be collected into the copper / gold concentrate during flotation.

The process plant design provides for a nominal 8.0 Mtpa of ore throughput. While gravity classification, secondary gravity classification and gold room circuits have been designed, installation has been deferred pending confirmation of the need for gravity concentration to meet designed overall gold recoveries.

The unit operations comprise of:

•Primary crushing and crushed ore stockpile.

•SABC grinding and pebble crushing.

•Flotation and regrinding.

•Flotation concentrate and tailings thickening.

•Flotation concentrate filtering, storage and loadout.

•Tailings filtration, conveying and paste fill production.

•Reagent preparation and services.

Project Infrastructure

The principal waste streams generated from the Project are the overburden and waste rock from the open pit mining and underground development and the tailings from the mineral processing operations. Overburden and waste rock will be stored on surface and tailings is expected to be used underground as paste backfill with the remainder being stored on surface. The project mine plan and material balance has been developed such that overburden and waste rock is entirely used for construction requirements eliminating the need for a separate waste rock dump. The waste management plan has been developed to provide for surface storage of waste streams in the IEWMF all within one watershed.

The water within the Project site can be classified into two categories, contact water and non-contact water. Non-contact water is surface water that is diverted around the mine facilities without being exposed to mine infrastructure, using a series of diversion drainage ditches and groundwater resulting from mine dewatering. Contact water includes groundwater and surface water that falls in the form of precipitation and has been exposed to mine infrastructure. A numerical groundwater model was developed for the Project utilizing site specific data from field investigations to estimate the dewatering rates for contact and non-contact water.

The Project is well situated to take advantage of Greece’s modern transportation network for shipment of construction and operations freight. The main access road connects the process plant and mining area with the national road network. The major regional center of Thessaloniki is approximately 80 km away and is accessed by highway EO 16. Thessaloniki has an international airport and one of Greece’s largest seaports. Thessaloniki is linked to the rest of Greece by Greece’s National Roadway, which has been extensively modernized in the last 20 years. Access to Europe and Türkiye is provided by the highway and rail infrastructure. The Skouries Project site substation is fed from a new overhead 6 km long 150 kV transmission line connected to the national power grid. Hellas Gold has signed an agreement with the Independent Electricity Transmission Operation for Greece (ADMIE) in 2015 that sets out the terms and conditions for connecting to the Greek power grid. The high voltage substation constructed for the Skouries Project has a power capacity of 51 MW.

Permitting

The technical study submitted to the MOE for the Skouries Project was initially approved in February 2012. After numerous supplements relating to flotation plant, Tailings Management Facility (TMF) arrangements and “auxiliary temporary facilities”, approval by the MOE was granted in 2013 - 14. An updated technical study covering amended aspects of the process plant and associated infrastructure was submitted to the MOE in December 2015, and this was approved in May 2016.

Subsequently, an updated specific technical study for the flotation plant was submitted to the MOE and approved on November 11, 2016. An update of the installation permit for the flotation plant was submitted by August 2016 and this was approved on September 3, 2019.

An Investment Agreement which amends the 2003 Transfer Agreement and provides a modernized legal and financial framework to allow for the advancement of Eldorado’s investment in the Kassandra Mines

46

was ratified into Greek law in early 2021. After the 2019 Greek Parliamentary elections, when Eldorado initiated talks with the newly established government, outstanding routine permits were released.

Hellas Gold has provided a €50.0 M Letter of Guarantee to the MOE as security for the due and proper performance of rehabilitation works in relation to the mining and metallurgical facilities of the Kassandra Mines project and the removal, cleaning, and rehabilitation of the old, disturbed areas from the historical mining activity in the wider area of the project. Additionally, a Letter of Guarantee to the MOE, in the amount of €7.5 M, has been provided as security for the due and proper performance of the Kokkinolakkas TMF.

Capital and Operating Costs

The capital costs indicated in this section are those which are listed in the Skouries Technical Report. On February 22, 2024, Eldorado issued a news release which included a revised capital estimate for the Skouries Project. Please see the section entitled “Capital Update” which follows the summary of the Skouries Technical Report.

The total Skouries Project capital cost includes the remaining cost to complete the Skouries Project construction until commercial production is achieved (‘initial capital’), and subsequent sustaining capital costs spread out over the remaining 20 years of the mine life. Capital costs are summarized in Table 1-4. Sunk costs to the end of 2021 are not included in the capital cost estimate. The accuracies of the cost estimates are consistent with the standards outlined by the Association for the Advancement of Cost Engineering (AACE). The cost estimate is a feasibility-level estimate categorized as AACE Class 3. Direct costs were developed from a combination of budget quotes, material take-offs, existing contracts, Project-specific references, and historical benchmarks. Indirect and owners’ costs were estimated using a combination of existing commitments, calculated project requirements, and historical benchmarks. Contingency was applied to each cost item in the estimate, based on the level of engineering definition and reliability of its unit rates

Note: Numbers may not compute exactly due to rounding.

(1) The Skouries Project pre-development capital was subsequently updated by the company in February 2024. See “Capital Update” below. 

The operating cost estimate provides the LOM operating costs associated with mining, the process plant, tailings filtration plant, backfill plant, WTP, water systems, and general and administrative (G&A) facilities.

47

The operating cost includes all on-site costs from mining through to the production of copper concentrate, including tailings filtration, tailings compaction, and paste production.

The operating cost estimate has been developed on a year-by-year basis in accordance with Eldorado’s envisaged operations and mine plan. The estimated total costs by cost centre and cost category are presented in Table 1.5.

A €/US$ exchange rate of 1.2 was used for the preparation of the operating costs. The cost per tonne averages for the open pit and underground mining are calculated based on the tonnages mined for the production years of those phases. The non-mining cost centre expenditures are averaged based on the process plant ore throughput for the production years. The operating cost excludes cost associated with pre-production years.

Table 1-5: Operating Costs

Cost Centre	Production years total cost (US$ M)	Production years cost per tonne of production ore (US$/t)
Open pit mining	245	4.24*
Underground mining	1,681	19.32*
Process plant	1,247	8.54
Tailings filtration plant	314	2.15

Total	3,944	26.99

The economic analysis is based on the Mineral Reserves production schedule, mill feed, metal recoveries and the capital and operating costs. The Skouries Project case metal prices used in the economic model are US$1,500/oz Au and US$3.85/lb Cu. The economic model was also evaluated at the respective Mineral Reserve gold and copper prices of US$1,300/oz and US$2.75/lb. The model makes use of a first principles build-up in Euros, with values then converted to US$. All reporting is in US$.

The after-tax cash flow analysis shows that the Skouries Project provides a robust return on the remaining capital to complete the Skouries Project scope and bring the Skouries Project into commercial production. An internal rate of return (IRR) of 19% on an after-tax basis is achieved with the project case metal prices of US$1,500/oz Au and US$3.85/lb Cu. Using those metal prices, the net present value (NPV) of the Skouries Project is estimated to be US$1,273M using a discount rate of 5%, with a payback of the remaining capital expenditure achieved in 3.7 years from the start of commercial production.

The economic model was subjected to a sensitivity analysis to determine the effects of changing metal prices, operating costs and capital costs on the Skouries Project financial returns. The results of the sensitivity analysis are provided in Table 1-6 to Table 1-9.

A test of economic extraction for the Skouries Mineral Reserves is demonstrated by means of a sensitivity analysis (see below). At the Mineral Reserve metal prices of US$1,300/oz Au and US$2.75/lb Cu the Project shows positive economics. The after-tax IRR is 9.8% and the NPV is estimated to be US$354M using a 5% discount rate, with a calculated payback period of 8.1 years from start of Commercial Production. Corporate income tax rates in Greece are 22% of net earnings. Income from operations can be offset by operating costs and by depreciation of capitalized items according to a schedule of depreciation based on the type of asset.

The sensitivity analysis shows that the Skouries Project is most sensitive to metal prices, followed by operating costs and then capital costs. The copper concentrate grade is the least sensitive. The sensitivity ranges show that the Skouries Project is also robust when evaluated using lower metal price assumptions, or higher operating and capital costs. Positive cash flows and positive NPV are maintained at metal prices of US$1,125/oz Au and US$2.89/lb Cu (except for when the NPV is discounted at 8%), operating and capital cost increased by 25% individually, or concentrate grade reduced by 25%.

Capital and Schedule Update

On February 22, 2024, Eldorado provided an updated Skouries capital cost estimate. This section is separate from the Skouries Technical Report and was approved by Simon Hille in his capacity as an Eldorado Qualified Person.

After finalizing key contracts in 2023, the Skouries capital cost estimate remained in line with the December 2021 feasibility study estimate. Through a diligent tendering process, more recent and pending contracts incorporate labor rates and labor hours that are higher than the feasibility study. This has resulted in a revised pre-production development capital estimate of $920 million, an increase of 9% over the original “Total pre-production development capital” estimate of $845 million disclosed in Table 1-4 Capital Cost Summary above.

The time invested in diligently negotiating the key project contracts has increased execution confidence with a modest effect on the production schedule. First production of the copper-gold concentrate is now expected in the third quarter of 2025 from prior guidance of mid-2025. As such, the 2025 gold production range has been lowered to between 50,000 to 60,000 ounces from prior guidance of 80,000 to 90,000 ounces. Copper production is expected to be between 15 to 20 million pounds in 2025. A steep ramp up curve is expected over the second half of 2025 and remains on track for commercial production at the end of 2025. We are assessing our plans with the goal of increasing our 2026 gold and copper production profile at Skouries.

Lamaque

To provide further clarity, on a go-forward basis, the Company is referring to specific assets within the Eldorado Québec portfolio as the Lamaque Complex. The Lamaque Complex (as previously defined), includes the Triangle Mine (Upper and Lower), the Ormaque Deposit, the Parallel Deposit, the Plug #4 Deposit, and the Sigma mill.

Technical Report

The scientific and technical information regarding the Lamaque Complex in this AIF is primarily derived from or based upon the scientific and technical information contained in the technical report titled “Technical Report for the Lamaque Project, Québec, Canada’’ with an effective date of December 31, 2021 prepared by Eldorado Gold Corporation including Eldorado employees Jacques Simoneau, géo, Peter Lind, P. Eng, Ertan Uludag, P. Geo, Sean McKinley, P. Geo, Jessy Thelland, P. Geo, Mehdi Bouanani, P. Eng, Vu Tran, P. Eng, David Sutherland, P. Eng and Michael K. Murphy, P. Eng of Stantec Consulting, all of whom are “Qualified Persons” under NI 43-101. The report is available under Eldorado Gold’s name on SEDAR+ and EDGAR.

Project Description, Location and Access

The Lamaque Complex is situated near the city of Val-d’Or in the province of Quebec, Canada, approximately 550 km northwest of Montreal. The coordinates for the approximate center of the host of the mineral reserves, the Triangle deposit, are latitude 48°4’38” N and longitude 77°44’4” W. The properties that form the Lamaque Complex represent the amalgamation of three separate but contiguous properties: Lamaque South, Sigma-Lamaque, and Aumaque, previously registered to lntegra Gold and Or lntegra. The Sigma mill is accessed via the Provincial Highway 117, 1.4 km east of Val-d’Or. The Triangle mine site is accessed from the south of Val-d’Or, 3.7 km east along a private gravel service road, Voie de Service Goldex-Manitou.

The city of Val-d’Or has a humid continental climate that closely borders on a subarctic climate. Winters are cold and snowy, and summers are warm and damp. All requirements, including a quality supply of hydro-electric power to support a mining operation, are available in Val-d’Or, and there is an ample supply of water on or near the Lamaque Project to supply a mining operation. Also available is a local skilled labor force with experienced mining and technical personnel.

The Abitibi region has a typical Canadian Shield-type terrain characterized by low local relief with occasional hills and abundant lakes. The mine site is bordered to the north by a large unpopulated wooded area, a portion of which is currently used for tailings and waste rock disposal.

The corporate tax rate in Quebec is 26.5%. The Quebec Mining Tax is applied based on a sliding scale according to profit margin with rates of 16% / 22% / 28%.

History

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 Complex mines starting in the early 1930’s. More recently, Eldorado acquired the Lamaque Project through the purchase of lntegra Gold Corp in 2017. Eldorado achieved commercial production on March 31, 2019, from ore mined at the Upper Triangle deposit and processed at the refurbished Sigma mill.

Geological Setting, Mineralization and Deposit Types

The Lamaque Complex is located in the Val-d’Or district of the eastern Abitibi Greenstone Belt within the Superior Province of the Canadian Shield. Known deposits and mineral occurrences in the project area, including the Triangle deposit, are sulphide-poor quartz veins or quartz-tourmaline-carbonate veins typical of many of the orogenic gold deposits in the region. Host rocks consist of volcanic flows and volcaniclastic rocks of the Val-d’Or Formation, intruded by a variety of intermediate to mafic intrusions in various forms including plugs, dykes and sills. Mineralized veins occur dominantly as shear veins within faults and shear zones cutting these units, and to a lesser degree as secondary splays and extension veins. These veins are preferentially localized within the mafic intrusions and in the host volcanic sequence proximal to the intrusions, which provide a competent host for the emplacement of gold-bearing quartz- tourmaline veins.

Current gold resources at the Lamaque Complex are defined in the Triangle, Plug No. 4, Parallel and Ormaque deposits, with most resources occurring in the Triangle and Ormaque deposits. The Triangle deposit is localized within and peripheral to a feldspar porphyritic diorite intrusion referred to as the Triangle Plug. Gold mineralization in the Triangle deposit occurs in shear-hosted quartz-tourmaline-carbonate-pyrite veins cutting the Triangle Plug and extending into the surrounding mafic lapilli-blocks tuffs. The thickest and most continuous veins are localized within east-west striking ductile-brittle reverse shear zones dipping 50-70° south. Veins also occur as extensional shear vein splays dipping 20-45° south as well as subhorizontal extension veins. Gold occurs within the veins as well as in the silica-sericite-carbonate-pyrite alteration selvages flanking the veins.

The Ormaque deposit occurs mainly within the C-porphyry diorite, also the principal host to the Sigma deposit, along its contact with andesitic volcaniclastic rocks of the Val-d’Or Formation. High gold grades are associated with quartz-carbonate-tourmaline veins, both within the veins themselves and in tourmaline-flooded wall rocks. Coarse visible gold is common. The mineralized veins are extensional veins to hybrid extensional shear veins typically dipping 10° to 25° WSW. Both are spatially associated with steeply NNW-dipping ductile-brittle fault zones. This vein-fault geometry is similar to that present at the historical Mine #2, located between the Ormaque deposit and the Sigma Mine.

The Plug No. 4 deposit, located 550 m north of the Triangle deposit contains mineralized veins restricted to a subvertical fine to medium-grained cylinder-shaped gabbro intrusion measuring roughly 100 to 150 m in diameter. East-west striking reverse shear zones dipping between 45° and 75° to the south cut the intrusion and host gold-bearing quartz- tourmaline-carbonate-pyrite veins. Mineralized extensional shear veins dipping 35-45° south are associated with these but have limited lateral continuity. Sub-horizontal extensional veins occur in vein arrays or clusters that extend for tens of metres down the central core of the gabbro intrusion. The thickness of individual veins can vary from 1 mm to 1.25 m, with most around 5-10 cm. These vein clusters can carry significant gold concentrations, but grades are erratic.

Mineralized zones at the Parallel deposit occur as sub-horizontal extension veins at shallow depths (70-200 m) and as shear veins dipping approximately 30-45° south at deeper levels. The mineralized veins consist of quartz and carbonate with lesser amounts of tourmaline, chlorite and sericite, hosted within fine- to medium-grained porphyritic diorite. The sub-horizontal extension veins are laterally extensive (up to 300 m), occur in en echelon patterns and exhibit pinch and swell characteristics. In general, they occur in stacked sets 10-25 m thick each containing up to 7 or 8 individual veins. Shear veins occur as up to four parallel veins within a 75 m wide corridor. Individual shear veins typically range in width from 15 cm and 1.5 m, but can be up to 2.6 m thick locally.

Gold mineralization is also documented in numerous zones which are peripheral to the four above deposits. These show similar styles of vein control and host rock characteristics as the three deposits discussed. The principal zones currently defined at the project include: Fortune Zone; No. 5 Plug (including No. 35 Vein); No. 3 Mine (including No. 1 and 2 Veins); South Triangle Zone; Mylamaque Zone; No. 4 Vein; No. 6 Vein; Sixteen Zone and Sigma East Zone. In addition, both the Sigma mine and Lamaque mine contain significant zones of residual mineralization not exploited during the historical mining of these deposits.

Exploration

Exploration in the Val-d’Or area has been on-going for nearly a century. Since the acquisition of lntegra Gold Corp. by Eldorado in 2017, significant exploration activities occurred at Triangle as well as several other targets including Plug No. 4, Parallel, Aumaque, South Gabbro, Lamaque Deep, Vein No. 6, P5 Gap, Sigma East Extension, Sector Nord, amongst others. In January 2020, Eldorado announced the discovery of the Ormaque deposit. Eldorado continues to explore the Lamaque Complex property extensively.

Drilling

Drilling on the Triangle, Parallel, Plug No. 4, and Ormaque deposits amount to 3,330 completed drill holes totaling some 821,284 m. Much of the drilling has been completed since 2015, and in 2015 Eldorado took over the responsibilities for planning, core logging, interpretation and supervision and data validation of the diamond drill campaigns. Drilling was done by wireline method with NQ sized core (47.6 mm nominal core diameter) for exploration and conversion drilling and BQTK/BTW sized core for definition (grade control) drilling.

In 2023, drilling at Lamaque included 67,665 m of resource conversion drilling and 38,365 m of exploration drilling testing for resource expansion and early-stage targets.

Sampling, Analysis and Data Verification

Geology and geotechnical data are collected from the core before sampling. All vein and shear zone occurrences are sampled with additional “bracket sampling” into unmineralized host rock on both sides of the veins or shear zones. Typically, about 50% of a hole is sampled. The core is cut at Eldorado’s core facility in Val-d’Or, Quebec. For security and quality control, diamond drill core samples are catalogued on sample shipment memos, which are completed at the time the samples are being packed for shipment. Standards, duplicates, and blanks are inserted into the sample stream by Eldorado staff.

Sample preparation procedures including an initial crush to 10 mesh followed by a riffle split of a 250 g subsample which was pulverized to 85% passing 200 mesh. This subsample is sent for assay where a 30 g subsample is taken and fire-assayed with an atomic absorption (AA) spectrometry finish. Any values greater than or equal to 5 g/t Au were re-assayed by fire assay using a gravimetric finish. The sample batches contained QA/QC samples comprising standard reference materials (SRMs), duplicates and blanks. It is in the QP’s opinion the QA/QC results demonstrate that the Lamaque Project database for assays is sufficiently accurate and precise for resource estimation.

The QP concluded that the data supporting the Lamaque Project resource work is sufficiently free of error to be adequate for estimation. Eldorado has established a complete and thorough data verification protocol to ensure proper accuracy and validity of all data incorporated (and not limited to) diamond drill hole deviation, assays, geological modeling, mine scheduling, economical analysis, etc

Mineral Processing and Metallurgical Testing

The metallurgical responses of ores from Upper Triangle are well understood given three years of operating data and extensive metallurgical testwork that has been completed. Tests included chemical analyses, comminution test work, gravity concentration tests, whole ore cyanidation tests, carbon gold loading tests, cyanide destruction tests as wells as thickening, rheology, and filtration test work. High metallurgical recoveries (96 - 97%) are obtained with the Upper Triangle ores and require a fine grind size (40 µm P80), long retention time (>70 hours), and high pH.

Recent testwork programs have focused on samples from Lower Triangle (zones C6 through C10) and the Ormaque deposit. Testwork programs have been carried out by third-party commercial laboratories.

Compared to ore from Upper Triangle, the Lower Triangle samples are slightly harder with a Bond Ball Mill work index of 12.8 kWh/t to 13.5 kWh/t. Recoveries from Lower Triangle are slightly lower than Upper Triangle, with an expected recovery of 95%. Samples tested from Ormaque indicate that the mineralized material is somewhat harder at 14.2 kWh/t and with metallurgical recoveries in line with Upper Triangle (96.5%) ores. A higher proportion of coarse gravity-recoverable gold was noted with the Ormaque samples.

Mineral Resource and Mineral Reserves Estimates

The Mineral Resource estimate for the Triangle deposit used data from both surface and underground diamond drillholes. The resource estimates were made from 3D block models created by utilizing

54

commercial geological modelling and mine planning software. The block model cell size is 5 m east by 5 m north by 5 m high. The mineral resources of the Triangle deposit were classified using logic consistent with the CIM Definition Standards referred to in NI 43-101. The mineralization of the project satisfies sufficient criteria to be classified into measured, indicated, and inferred mineral resource categories. Mineral resources that are not mineral reserves have no demonstrated economic viability.

The Mineral Resources for the Triangle deposit, as of September 30, 2023, are shown in Table 1-1. The resources include 20 kt in surface stockpiles as of the end of September 2023. The Mineral Resources are reported within the constraining mineralized domain volumes that were created to control resource reporting and are based on a 3.0 g/t gold cut-off grade.

Table 1-1: Triangle Mineral Resources, as of September 30, 2023

Deposit Name	Categories	Tonnes (x 1,000)	Grade Au (g/t)	Contained Au (oz x 1,000)
Upper Triangle	Measured	1,356	7.92	345
	Indicated	4,462	7.68	1,103

	Inferred	1,428	6.89	316
Lower Triangle	Indicated	61	7.78	15
	Inferred	7,620	7.46	1,828

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 utilizing commercial geological modelling and mine planning software. The block model cell size is 5 m east by 5 m north by 5 m high. The block model was not rotated.

The mineral resources of the Parallel deposit were classified using logic consistent with the CIM Definition Standards for Mineral Resources and Mineral Reserves referred to in NI 43-101. The mineralization of the project satisfies sufficient criteria to be classified into indicated and inferred mineral resource categories. Mineral resources that are not mineral reserves have no demonstrated economic viability.

The Mineral Resources for the Parallel deposit, as of September 30, 2023, are shown in Table 1-2. The mineral resources are reported within the constraining domain volumes that were created to control resource reporting and at a 3.0 g/t gold cut-off grade.

Table 1-2: Parallel Mineral Resources, as of September 30, 2023

Deposit Name	Categories	Tonnes (x 1,000)	Grade Au (g/t)	Contained Au (oz x 1,000)
Parallel	Indicated	221	9.87	70
Parallel	Inferred	200	8.83	57

Due to its similarity with the Triangle deposit, the same classification approach is used in the Parallel deposit, where the average distance of the samples to a block center interpolated by samples from at least two drill holes, up to 30 m was classified as indicated mineral resources. All remaining model blocks containing a gold grade estimate were assigned as inferred mineral resources.

The Mineral Resource estimate for the Plug #4 Zone used data from surface diamond drillholes. The resource estimates were made from 3D block models created by utilizing commercial geological modelling and mine planning software. The block model cell size is 5 m east by 5 m north by 5 m high. The block model was not rotated.

The mineral resources of the Plug #4 Zone were classified using logic consistent with the CIM Definition Standards referred to in NI 43-101. The mineralization of the project satisfies sufficient criteria to be classified into indicated and inferred mineral resource categories. Mineral resources that are not mineral reserves have no demonstrated economic viability.

The Mineral Resources for the Plug #4 Zone, as of September 30, 2023, are shown in Table 1-3. The mineral resources are reported within the constraining domain volumes that were created to control resource reporting and at a 3.0 g/t gold cut-off grade.

Due to its similarity with the Triangle deposit, the same classification approach is used in the Ormaque deposit, where the average distance of the samples to a block center interpolated by samples from at least two drill holes, up to 30 m was classified as indicated mineral resources. All remaining model blocks containing a gold grade estimate were assigned as inferred mineral resources.

The Mineral Resource estimate for the Ormaque deposit used data from surface diamond drillholes. The resource estimates were made from 3D block models created by utilizing commercial geological modelling and mine planning software. The block model for Ormaque has a fixed horizontal length of 5 m and a varying length in for the Z axis between 0 and 5 m.

The mineral resources of the Ormaque deposit were classified using logic consistent with the CIM Definition Standards for Mineral Resources and Mineral Reserves referred to in National Instrument 43-101. The density of drillhole data and the continuity of mineralization at Ormaque only supports an inferred classification for all resources. Mineral resources that are not mineral reserves have no demonstrated economic viability.

The Mineral Resources for the Ormaque deposit, as of September 30, 2023, are shown Table 1-4. The mineral resources are reported within the constraining volumes that were created to control resource reporting at a 3.5 g/t gold cut-off grade.

Table 1-4: Ormaque Mineral Resources, as of September 30, 2023

Deposit Name	Categories	Tonnes (x 1,000)	Grade Au (g/t)	Contained Au (oz x 1,000)
Ormaque	Indicated	309	19.24	191
Ormaque	Inferred	1869	15.43	927

The Mineral Reserve estimate is based on Measured and Indicated Mineral Resources for the Upper Triangle and Parallel deposits, upon which the mining plan and economical study have demonstrated economical extraction. Mineral reserves are reported using a gold price of US$ 1,400 per ounce and an exchange rate of 1.30 CA$/1.00 US$. A cut-off grade of 5.06 g/t after dilution was applied at stope scale for discrimination of material to be retained in reserves and all stopes falling below cut-off were taken out of the mine plan. Isolated stopes with grade barely above cut-off were taken out of the reserves if their extraction could not support the cost of development. From a marginal cut-off grade perspective that considers sunk cost, mandatory development in mineralized ore was included in the reserves if it graded at least 1.0 g/t.

Areas of uncertainty that may materially impact the Mineral Reserve estimates include and are not restricted to:

•Gold market price and exchange rate.

•Costs assumptions, in particular cost escalation.

•Geological complexity and continuity.

•Dilution and recovery factors.

•Geotechnical assumptions concerning rock mass stability.

Orebody wireframes were produced on LeapFrog Geo software and an interpolated block model was produced by MineSight (MinePlan) software. Using Deswik Stope Optimizer Module, stope shapes were created using the following constraints and modifying factors:

•Only material falling in the Measured and Indicated Resources was retained for inclusion in Mineral Reserves.

•Mining Method considered a vertical height of 25 m, Minimal dip 45° and stope width between 3 m and 10 m for Longitudinal Retreating Long Hole method with stope lengths up to 25 m. For Transverse Primary/ Secondary Long Hole method, a minimal dip of 45 ° and stope width greater than 10 m was considered with stope lengths of 15 m.

•External dilution of 25%.

•Ore Development incorporated internal, planned dilution, and considered 100% mining recovery with no-over break.

56

•Development material grading at least 1.0 g/t was included if the development is mandatory.

•Mining Recovery of 95% and metallurgical recovery of 97%.

The Mineral Reserve estimate as prepared by Eldorado Québec is summarized in Table 1-5 and has an effective date of September 30, 2023. All Mineral Reserves are classified using the CIM Definition Standards for Mineral Resources and Reserves (May 10, 2014) that are incorporated by reference into NI 43-101.

Mineral Resource and Mineral Reserve estimates for Lamaque may be affected by technical and other relevant factors which are more specifically described in our "Risk Factors" section.

Mining Methods

The primary mining method that is currently used at Lamaque is mechanized longhole stoping. The existing mobile equipment fleet of conventional equipment, mine infrastructure, and services, as well as workforce skill sets are based on longhole, and this method will continue to be used. Ore is transferred to surface using 45-tonne rated underground haulage trucks in the newly developed Sigma Ramp to the surface ore pad near the Sigma mill facility. The current longhole stoping mining method will be maintained in the proposed mining of the Lower Triangle deposit

In the proposed mining of the Ormaque deposit, Drift-and-Fill (DAF) mining methods is expected to be employed due to the shallowly-dipping orientation of the mineralized zones, allowing for near-complete recovery of mineralization and providing better selectivity while allowing low grade material to be left in the stopes. New low-profile mining equipment will likely be required to reduce mining heights to 3.0 m and reduce external dilution.

The mine operation is currently using cemented rockfill (CRF) and unconsolidated rockfill as backfill. In the proposed Lower Triangle and Ormaque mine plans, addition of a paste fill plant is under evaluation to provide cemented paste fill. Mineralized material will continue to be transferred to surface using underground haulage trucks. The newly developed Sigma-Triangle decline to the surface ore pad near the Sigma mill facility is a recent improvement for material handling to the mill. Where practical, waste rock will remain underground for use as backfill.

Processing and Recovery Methods

In 2024, Lamaque is expected to mine and process approximately 870,000 to 910,000 tonnes of ore. This corresponds to a plant throughput of 110 tonnes per operating hour at peak feed rate of 2,500 tonnes per day. This throughput is within the demonstrated performance of the plant.

The Sigma mill operates a conventional process including:

•Primary jaw crusher and secondary cone crusher;

•Grinding circuit consisting of a 9’ x 12’ rod mill, and two 12’ x 14’ ball mills;

•Gravity concentration;

•Leach circuit (7 tanks);

•Carbon-in-pulp (CIP) circuit (7 tanks);

•Elution, carbon regeneration, and areas.

57

Metallurgical recoveries through the Sigma mill are consistently above 96%. Expected recoveries for Upper Triangle ores are 97%. For Lower Triangle materials, expected recoveries are slightly lower at 95% and for Ormaque expected recoveries are 96.5%. Recoveries have been slightly higher during the summer period due to the positive benefit of higher leach temperatures.

Infrastructure

The Triangle mine site consists of the following buildings built as part of the current mine surface infrastructure:

•A two-story building housing administration, technical services and operations offices. It also includes a dry facility for 400 people.

•A garage with six working bays, a warehouse, a compressor room and offices to serve maintenance and procurement teams;

•A set of buildings next to the main ventilation raise for main fans, heating system and compressor room;

•A complete diamond drill core logging facility;

•A cement slurry plant and a dry cement silo connected to the underground via piping;

•Prefabricated modules housing offices and dry facilities for the site contractors; and

•Several fabric buildings to serve as cold storage.

•Surface fuel station connected to underground delivery piping.

Lamaque contains three slurried tailings facilities. Tailings are currently being deposited at the tailings facility located adjacent to the Sigma mill, designated as the Sigma Tailings Management Facility. A second TMF is located at the Aurbel site, designated as the Aurbel TMF. The third tailings facility is located within the operational area of Lamaque, designated as the Lamaque TMF. No tailings are currently being deposited to the Aurbel TMF or Lamaque TMF.

In 2021, Eldorado established an independent tailings review board (ITRB)to provide technical guidance on design and operational practices at its tailings facilities. Independent reviews of all tailings facilities are completed on a regular basis.

Since 2020, in addition to the usual daily and monthly inspections, instrumentation with telemetry, including piezometers, inclinometers and tensiometer has been installed across the Sigma tailings facility, to help to monitor the behaviour of the dykes. The ITRB advises on the design, the construction and the operating process of the tailings management facility to ensure that reflects industry best practices.

The Lamaque Complex includes significant fixed infrastructure in place at the Triangle deposit and the Sigma mill. This includes an underground ramp system currently extending to 775 m depth, with approximate dimensions of 5.1 m x 5.5 m that provides access to the ore zones on 18 m vertical intervals in the upper mine and 25 m vertical intervals in centers of production below 275 m level. A ventilation system with two 1500 hp surface fans and multiple 3.4 m – 7.3 m diameter raise connections to levels in the mine which provide sufficient air for underground operations. The airflow is heated with natural gas burners in winter months. A cement slurry mixing and distribution system is for use in the backfilling of stopes with cemented rockfill. A series of surface buildings including the mine site offices, mine dry, workshop, warehouse, contractor offices, laydown yards, diesel storage, explosives magazine and stockpile pads for ore and waste are available and capable of supporting the current operations at the Triangle site.

The ore from the Triangle site is processed at the Sigma mill. This infrastructure was largely in place at the Sigma mill and used by past operators. Future planned infrastructure includes continuation of the main ramp to develop the Upper Triangle resources and potential ore zones of the Lower Triangle deposit in Lower Triangle. An upgraded cyanide destruction circuit is in place. Investigations are underway to feed this slurry to a potential new paste tailings plant for use in underground backfill systems.

The Lamaque Complex operations include a diverse fleet of owner operated underground mining equipment including underground haulage trucks ranging from 30-tonne to 45-tonne underground loaders ranging in size from 3.1 to 7.6 m3, development jumbos, production drills, mechanized bolters, and support equipment such as scissor lifts, personnel carriers, backhoes, boomtrucks, explosive loaders and others. One 50-tonne electric (BEV) Sandvik truck was put into use in 2023 and a second is expected to join the fleet in the first quarter of 2024.

Capital and Operating Costs

A summary of capital costs required to mine and process the current Reserves follows in Table 1-6:

Table 1-6: Summary of Capital Costs

Growth Capital	LOM Total ($M)
Tailings	$79.7
Other	$0.5
Subtotal	$80.2
Sustaining Capital
Mine	$249.2
Process	$18.9
Finance / Administration	$1.4
Subtotal	$269.5
Capitalized Exploration	$26.0
Total Capital Costs	$375.7

A summary of operating cost follows in Table 1-7:

Table 1‑7: Summary of Operating Costs

Area	LOM average (US$/t processed)
Mining	$92.90
Processing	$25.10
Site General & Administrative	$30.14
Total Mine Operating Costs	$148.14

Production, cash operating cost per ounce, and sustaining capital for 2023 and forecasts for 2024 are as follows in Table 1-8:

Table 1-8: Production, Cash Cost, and Sustaining Capital Summary

	2023	2024 Forecast
Production	177,069 oz	175,000 - 190,000 oz
Cash Operating Cost per ounce sold	$643
Total Cash Cost per ounce sold1		$ 700 - 800
Sustaining Capital	$ 72.7 M	$ 85 - 95 M

1 As we have issued AISC/oz guidance by site in 2024, in addition to continuing total cash cost/oz guidance, we have previously announced that we will cease reporting of cash operating cost/oz in Q1 2024. The table above therefore reflects historic and forecasted reporting metrics, which will not be directly comparable.

In 2024, Lamaque is expected to mine and process approximately 870,000 to 910,000 tonnes of ore at an average gold grade of 6.3 to 6.8 grams per tonne. Total cash costs per ounce sold are expected to be slightly higher compared to 2023, as a result of an increase in the use of consumables (fuel, cyanide, explosives) and increased labour costs.

Sustaining capital expenditures for 2024 are expected to be approximately $85 to $95 M, which includes significant underground mine development and resource conversion drilling at Triangle. Expected growth capital for 2024 of $17 to $22 M includes non-sustaining exploration expenditures for resource conversion and resource expansion drilling at the Ormaque deposit, tailings management, development to Ormaque for a bulk sample, and electric underground trucks.

59

Expensed exploration programs in 2024 will focus on drill testing early-stage targets proximal to existing operations and historic mine development in the Sigma - Lamaque - Triangle area of the Lamaque Complex, continued target definition and exploration on the adjacent Bourlamaque property, and the generation of additional early-stage targets for future drill test consideration.

Non-Material Properties

Perama Hill

Perama Hill and Perama South, located 1.5 km southeast of Perama Hill, are epithermal gold-silver deposits located in the Thrace region of northern Greece. If developed, Perama Hill will operate as a small open pit mine that uses a conventional carbon in leach circuit for gold recovery. Project optimization and stakeholder engagement studies are ongoing.

Sapes Project

The Sapes project is located approximately 2 km east of the village of Sapes in northeastern Greece and is 14 km northeast from the Perama Hill project. Sapes was acquired in 2014 through Eldorado Gold’s acquisition of Glory Resources Ltd. We are currently reviewing the project to determine future technical, economic, permitting, social and environmental work.

Stratoni

Stratoni is an underground, silver-lead-zinc mine located in the Halkidiki Peninsula in northern Greece. As of December 13, 2021 Mavres Petres mine was placed under care and maintenance with the workforce being re-distributed to other operations of Hellas Gold.

Certej

The Certej mining concession was extended in January 2020 for an additional five years. In October 2022, the Company entered into an agreement to sell the Certej project. While the share purchase agreement expired on March 24, 2023, the Company is committed to continue its plan to sell its interest in the project within the next twelve months.

Bourlamaque

The Bourlamaque property covers approximately 20,000 hectares in Quebec contiguous with the Lamaque Complex. Eldorado has conducted exploration drilling on this property and is currently undertaking technical work to define future drill targets.

General Notes on the Tabulated Mineral Reserves and Mineral Resources

Mineral Reserves and Mineral Resources are reported on a 100% basis for each property and where applicable, are calculated to match the end of September 2023 mining as-builts. Except as described in this AIF, there are no known environmental, permitting, legal, taxation, political or other relevant issues that would materially affect the estimates of the Mineral Reserves and Mineral Resources. Estimates of Mineral Resources include Mineral Reserves.

Grade estimates for the Mineral Resources are based almost entirely on diamond drillhole samples. Sampling and analyses of these samples are governed by company-wide protocols to provide consistent and quality results. Analysis for gold, silver, copper, lead and zinc were done for the most part on sawn half core samples using fire assay, AAS and ICP analytical methods. These analyses and the proceeding preparation are strictly controlled by Eldorado’s Quality Assurance / Quality Control programs. These include standard reference materials, blank and duplicate samples that are regularly inserted prior to shipment from the preparation site. Results are used to monitor and control the quality of the assay data and only data that pass the thresholds set up in these programs are used in our resource estimates.

Except as otherwise described herein, the Mineral Reserve estimates incorporate adequate factors for ore loss and waste dilution. The Mineral Reserves are based on the following price assumptions:

Metal	Price	Relevant Properties
Gold (1)	$ 1,400/oz	Efemçukuru, Kışladağ, Lamaque, Olympias
Silver	$ 19.00/oz	Olympias
Copper	$ 2.75/lb	Skouries
Lead	$ 2,000/t	Olympias
Zinc	$ 2,500/t	Olympias

(1) Mineral Reserves for the Skouries and Perama Hill projects were determined based on a $1,300/oz gold price.

Resource classification into Measured, Indicated and Inferred Mineral Resources and Reserve classification into Proven and Probable Mineral Reserves used logic consistent with the definitions adopted by the Canadian Institute of Mining, Metallurgy and Petroleum (the definitions can be found at www.cim.org), and in accordance with the disclosure requirements of NI 43-101.

64

Eligible Mineral Resources for reporting fulfilled a demonstration of reasonable prospects for eventual economic extraction: The Mineral Resources used a long term gold metal price of $ 1,800/oz for the determination of 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 (Kışladağ, Perama Hill and Perama South) used pit shells created with the long term gold price to constrain reportable model blocks. Underground Mineral 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 (Skouries) have the open pit resources constrained by the permit, and underground resources constrained by a reporting shape.

Understanding Mineral Reserve and Mineral Resource Classification

A Mineral Reserve is the part of a Measured or Indicated Mineral Resource that can be economically mined, demonstrated by at least a preliminary feasibility study that includes adequate information about mining, processing, metallurgical, economic and other relevant factors that demonstrate (at the time of reporting) that economic extraction can be justified. See the definition of “Mineral Reserve” in the “Glossary” for more information.

Mineral Resources are concentrations or occurrences of minerals that are judged to have reasonable prospects for economic extraction. The location, quantity, grade, geological characteristics and continuity of a mineral resource are known, estimated or interpreted from specific geological evidence and knowledge. Mineral Resources are classified into Measured, Indicated and Inferred. Inferred Mineral Resources are not known with the same degree of certainty as Measured and Indicated Mineral Resources and do not have demonstrated economic viability. See the definition of “Mineral Resource” in the “Glossary” for more information.

Mineral Resources that have not already been classified as Mineral Reserves do not have demonstrated economic viability, and there can be no assurance that they will ultimately be converted into Mineral Reserves. Consequently, these Mineral Resources are of a higher risk than Mineral Reserves.

Understanding Estimates

Estimating Mineral Reserves and Mineral Resources is a subjective process. Accuracy depends on the quantity and quality of available data and assumptions and judgments made when interpreting it, which may prove to be unreliable.

The cut-off grades for the deposits are based on our assumptions for plant recovery, metal prices, mining dilution and recovery, and our estimates for operating and capital costs. We may have to recalculate our estimated Mineral Reserves and Mineral Resources based on actual production or the results of exploration.

Fluctuations in the price of gold, production costs or recovery rates can make it unprofitable for us to operate or develop a particular property for a period of time. See “Forward-looking information and risks” and “Risk factors in our business” for additional information.

Risk Factors in Our Business

Eldorado is involved in the exploration, discovery, acquisition, financing, development, production, reclamation and operation of mining properties. We face a number of risks and uncertainties which could have a material adverse effect on our business, results of operations, financial condition and the Eldorado Gold share price.

Management monitors risk using a risk management review process. Management prepares a risk assessment report every quarter outlining the operational and financial risks. The Board reviews the report to evaluate and assess the risks that the Company is exposed to in various markets, and discusses the steps management takes to manage and mitigate them.

The risks described below are not the only risks and uncertainties that we face. Although we have done our best to identify the risks to our business, there is no assurance that we have captured every material or potentially material risk and the risks identified below may become more material to the Company in the future or could diminish in importance. Additional existing risks and uncertainties not presently identified by the Company, risks that we currently do not consider to be material, and risks arising in the future could cause actual events to differ materially from those described in our forward-looking information, which could materially affect our business, results of operations, financial condition and the Eldorado Gold share price.

We have set out the risks in the order of priority we believe is appropriate for Eldorado based on our assessment of, among other things, the likelihood and impact of such risks, and our expected capabilities to mitigate such risks. Accordingly, you should review this section in its entirety.

Foreign Operations

Many of our operations are located in foreign jurisdictions, and are exposed to various levels of political, economic and other risks and uncertainties. These risks and uncertainties vary from country to country and include, but are not limited to:

•earthquakes, wildfires, floods and other natural disasters;

•changing political and social conditions, geopolitical environment or governments;

•timely receipt of necessary permits and authorizations;

•renegotiation or nullification of existing rights, concessions, licenses, permits and contracts;

•restrictions on foreign exchange, currency controls and repatriation of capital and profits;

•extreme fluctuations in currency exchange rates;

•high rates of inflation;

•labour unrest, rising labour costs, and labour shortages;

•mobility restrictions for personnel and contractors;

•civil unrest or risk of civil war;

•changes in law or regulation (including in respect of mining regulations, taxation and royalties);

•changes in policies (including in respect of monetary policies and permitting);

•bribery, extortion and corruption;

•expropriation;

•reliability of judicial recourse;

•operation of the rule of law;

•availability of procedural rights and remedies;

•sanctions relating to the Russia-Ukraine war;

•guerrilla activities, insurrection and terrorism;

•activism;

•hostage taking;

•military repression; and

•trespass, illegal mining, theft and vandalism.

The occurrence of any of these risks in the countries in which we operate could have a material adverse effect on our business, results of operations, financial condition and the Eldorado Gold share price.

The mining and metals sector has been increasingly targeted by local governments for the purposes of raising revenue or for political reasons, as governments continue to struggle with deficits and concerns over the effects of depressed economies. Governments are continually assessing the fiscal terms of the mining regimes and agreements that apply to an entity looking to exploit resources in their countries and

66

numerous countries have recently introduced changes to their respective mining regimes that reflect increased government control over, or participation in, the mining sector.

The possibility of future changes to the mining regimes in the countries in which we operate adds uncertainty that cannot be accurately predicted and may result in additional costs, delays and regulatory requirements. In addition, such changes could restrict our ability to contract with persons or conduct business in certain countries. There is no assurance that governments will not take our rights, impose conditions on our business, prohibit us from conducting our business or grant additional rights to state-owned enterprises, private domestic entities, special interest groups, indigenous peoples or residents in the countries in which we operate, which could have a material adverse effect on our business, results of operations, financial condition and the Eldorado Gold share price.

We expect to generate cash flow and profits at our foreign subsidiaries, and we may need to repatriate funds from those subsidiaries to service our indebtedness or fulfill our business plans. From time to time, governments in countries in which Eldorado operates may impose limitations on Eldorado's ability to repatriate funds. As such, we may not be able to repatriate funds from foreign jurisdictions in the future, or we may incur tax payments or other costs when doing so, as a result of a change in applicable law or tax requirements at local subsidiary levels or at the Eldorado Gold level.

We have one operating mine, two development projects and one mine on care and maintenance in Greece. Following the global financial crisis in 2008 and 2009, the Greek economy experienced a significant downturn.The subsequent economic crisis from 2011 to 2018 resulted in austerity measures, a severe recession of the Greek economy, capital controls from 2015 to 2019 and concerns about sovereign debt default and of Greece exiting the Eurozone. During this crisis, Greece experienced protracted political instability, a high unemployment rate, popular unrest in response to austerity measures and rounds of bail-out negotiations with various governmental and private parties. Since 2019, and to a large extent due to the economic measures adopted during the crisis, the Greek economy has been stabilized, and, as of 2023, the Hellenic Republic has been rated investment grade.Greece had national elections in May and June of 2023. While there can never be assurances on future political or economic circumstances, and the OECD and IMF still believe in further reforms, the current consensus is that the Greek economy has rebounded from the crisis and the outlook is broadly positive.

Following the 2019 Greek Parliamentary elections, the Company initiated talks with the newly established government. In February 2021, we entered into the Investment Agreement with the Hellenic Republic to govern the further development, construction and operation of the Skouries Project and the Olympias and Stratoni/Mavres Petres mines and facilities, which provides a modernized legal and financial framework to allow for the advancement of our investment in these assets. In March 2021, the Amended Investment Agreement was ratified by the Greek parliament and published in the Greek Government Gazette, officially becoming law.

We currently hold all necessary permits for our operations in Greece and the development of Skouries mine, but in the past we have experienced significant delays in the timely receipt of necessary permits and authorizations from the Hellenic Republic in order to advance operations in Greece, and it would be possible we will experience delays again in the future, notwithstanding the Investment Agreement. In addition, there is no assurance that Greece will not adopt legal, regulatory or policy changes in the future which may have a material adverse effect on our business, results of operations, financial condition and the Company’s share price.

We also have two producing mines that are located in Türkiye. Türkiye has historically experienced, and continues to experience, heightened levels of political and economic instability due to regional geopolitical instability. These conditions may be exacerbated by current global economic conditions or become exacerbated during electoral processes. In particular, there have been political challenges in and nearby to Türkiye, including civil unrest along the geographic borders with Syria, Iran and Iraq, terrorist acts, including bombings in major centres, and a refugee crisis. Türkiye also has a history of fractious governing coalitions comprised of many political parties and has experienced anti-government protests as well as unrest following investigations initiated in December 2013 into alleged government corruption, and an attempted coup in 2016. Our operations have experienced no significant disruptions due to these periods of instability and continue to operate under normal business conditions. However, there can be no assurance that a future period of instability will not negatively affect our current and future operations in Türkiye. Such a period of instability may also have a material adverse effect on our business, results of operations, financial condition and the Eldorado Gold share price.

In 2023, certain changes were made to the tax legislation of Türkiye which resulted in a $59.4 M hyperinflationary adjustment to the local tax basis in Türkiye. As a consequence we experienced larger deferred income tax recoveries than in 2022, although these changes were partially offset by the weakening of the Turkish Lira in 2023. In addition, in July 2023, Türkiye enacted income tax rate

67

increases which were retroactive to January 1, 2023. We cannot predict additional future changes to Turkish income tax legislation or their impact on our financial results.

Since late 2023, commercial shippers operating in the Red Sea have had to adjust to an environment of growing threats to the safety and security of their ships, cargo, and personnel (including rocket attacks, drone strikes, and attempts to seize or commandeer vessels, cargo and crew). These threats have continued into early 2024 and it is unclear if or when more normal conditions will resume in the region. In response to current conditions, many in the commercial shipping industry are facing increased costs for security and insurance.Other commercial shippers have chosen to redirect their traffic around the region entirely, foregoing the Suez Canal and Red Sea for a longer trip around the southern coast of Africa. These changes in the shipping industry have impacted our inbound and outbound shipping activities for Greece and Türkiye.We may experience delays, additional increases in costs, or an inability to send or receive certain materials or equipment in a timely or cost efficient manner. Shipping costs have already increased dramatically since late 2023 and could reach unsustainable levels for reasons beyond our control. In addition, if in the future any of our inbound or outbound shipping activities were impacted by the current conditions in the Red Sea, our commercial insurance policies in place may not provide coverage due to customary exclusions in place.

Aside from the Company’s own operations, the Red Sea is critical to global energy producers and connects various transportation hubs. Ongoing disruptions in the Red Sea have the potential to increase global energy prices significantly. This is a major input for the Company, as well as its suppliers and service providers (who may choose to pass higher costs on to the Company).

While the Company is attempting to mitigate these effects, there can be no assurance that the situation will not deteriorate further in the near or long term, which may negatively affect the Company’s current and future operations in Greece and Türkiye (or, in the case of rising global energy prices, internationally), and may have a material adverse effect on our business, results of operations, financial condition and the Eldorado Gold share price.

We operate in a range of environments and our employees, contractors and suppliers are at risk of injury, disease and natural disasters. On February 6, 2023, a significant earthquake struck the southeast of Türkiye resulting in severe loss of life, and damage to infrastructure in several towns and cities in the impact zone. Although our operations have experienced no significant disruptions due to this natural disaster, there is no guarantee that a similar natural disaster in the future, whether in Türkiye or in any other jurisdiction we operate in, will not have an adverse effect on our business, results of operations or financial condition. If our workforce is affected by high incidence of injury, disease or natural disasters, the facilities and treatments may not be available to the same standard that one would expect in more economically developed countries such as Canada and the United States, which could have an effect on the availability of sufficient personnel to run our operations. This could result in a period of downtime or we may be subject to an order to cease operations, which could have an adverse effect on our business, results of operations, financial condition and the Eldorado Gold share price. See also “Climate Change”.

The safety and security of our employees and associated contractors is of prime importance to the Company. Various security problems may occur in any of the jurisdictions in which we operate. We are at risk of incursions or acts of terrorism by third parties that may result in the theft of or result in damage to our property. We endeavor to take appropriate actions to protect against such risks, which may affect our operations or cause us to incur further costs.

Development Risks at Skouries and Other Development Projects

Gold and other metal exploration is highly speculative in nature, involves many risks and is often not productive; there is no assurance that we will be successful in our development efforts. Substantial expenditures are required to establish proven and probable mineral reserves, determine the optimal metallurgical process to extract the metals from the ore and to plan and build mining and processing facilities for new properties and to maintain such facilities at existing properties. Once we have found ore in sufficient quantities and grades to be considered economic for extraction, then metallurgical testing is required to determine whether the metals can be extracted economically. It can take several years of exploration and development before production is possible, and the economic feasibility of production can change during that time.

The capital expenditures and time required to develop new mines are considerable and changes in cost or construction schedules can significantly increase both the time and capital required to build the project, including in respect of the expected cost and construction schedule for the Skouries Project. Although development is currently underway, project development schedules are dependent on obtaining the support of local communities, obtainingthe governmental approvals necessary for the operation of a project, and if applicable, allowing for the necessary regulatory process to be completed with respect to

68

any new archaeological findings on the site. New mines may face opposition from local communities, and the timeline to obtain necessary government approvals is often beyond our control. See also “Indebtedness”, “Liquidity and Financing Risk”, and“Community Relations and Social License”.

It is not unusual in the mining industry to experience unexpected problems during the start-up phase of a mine, resulting in delays and requiring more capital than anticipated. As a result of the substantial expenditures involved in development projects, developments are prone to material cost overruns. While we have taken steps to mitigate this, including securing the Term Facility, there is no assurance that the profitability or economic feasibility of a project will not be adversely affected by factors beyond our control. Delays can also occur when production initially commences. In the past, we have adjusted our estimates based on changes to our assumptions and actual results. There is no guarantee that such adjustments will alleviate the effects of such delays or problems. These unexpected occurrences may also impact our compliance with certain terms, conditions, and covenants set out in the Term Facility and commercial and other material agreements related to the development of Skouries. See also “Liquidity and Financing Risk”.

Mine development projects typically require a number of years and significant expenditures during the development phase before production is possible and there is no assurance that any of our development projects will become producing mines.

Development projects depend on successfully completing feasibility studies and environmental assessments, obtaining the necessary government permits and receiving adequate financing. Economic feasibility is based on several factors, including:

•estimated mineral reserves;

•anticipated metallurgical recoveries;

•environmental considerations and permitting;

•future prices of gold, copper, and other metals;

•anticipated capital and operating costs for the projects; and

•timely execution of development plan.

Development projects have no operating history to base estimated future production and cash operating costs on. With development projects in particular, estimates of proven and probable mineral reserves and cash operating costs are largely based on:

•interpreting the geologic data obtained from drill holes and other sampling techniques; and

•feasibility studies that derive estimated cash operating costs based on:

•the expected tonnage and grades of ore to be mined and processed;

•the configuration of the ore body;

•expected recovery rates of gold and other precious and base metals from the ore;

•estimated operating costs; and

•anticipated climate conditions and other factors.

It is therefore possible that actual cash operating costs and economic returns will differ significantly from what we estimated for a project before starting production.

Mining of mineral bearing material requires removal of waste material prior to gaining access to and extracting the valuable material. Depending on the location of the ore, this may entail removing material above the ore in an open pit situation (pre-stripping), or developing tunnels underground to gain access to deeper material. Where possible, this material is then generally used elsewhere in the project site for construction of site infrastructure. As a project is developed, a plan is put forward to complete the pre-strip or required underground development so that mining of ore can commence in line with the overall schedule to feed ore to the process plant at the right time. The degree of pre-strip in an open pit is based on selected drilling, which may result in adjustments to the orebody model and a requirement for more or less pre-stripping to be completed. This may result in a deficit of material required to complete other earthworks around the project site, such as tailings facilities, or an increase in the pre-strip requirements prior to mining commencing. Similarly, with underground development, the mining method and optimized design is based on an amount of drilling that will be increased during normal operations. As work continues, there may be previously unknown ground conditions that are exposed, or other changes to mining parameters that can cause a change in the mine design or direction of the underground development. Either of these occurrences could result in more or less material than can be used for other site projects if so designed, and could also delay the start-up of continuous production. This may result in lower revenues while the project ramps up to normal operating rates.

In Greece, we have been undertaking a significant transformation process to improve the performance of the Kassandra Mines. We anticipate the possibility of work stoppages or slowdowns of a significant

69

duration as we move forward to achieve the necessary outcomes of the transformation process. As a result, production may be lower than initially anticipated during the course of this transformation. Any work interruptions involving our employees (including as a result of a slowdown, labour shortages, strike or lockout as permitted under applicable legislation), contractors or operations, or any jointly owned facilities operated by another entity, present a significant risk to Eldorado and could have a material adverse effect on our business, results of operations, financial condition and the Eldorado Gold share price. See also “Labour-Employee/Union Relations/Greek Transformation” and “Skilled Workforce”.

Our production, capital and operating cost estimates for development projects are based on certain assumptions. We use these estimates to establish our mineral reserve estimates but our cost estimates are subject to significant uncertainty as described above. Although we have undertaken significant work to understand and update our assumptions and estimates related to the Skouries Project and will continue this work on Skouries and our other development projects, actual results for our projects will likely differ from current estimates and assumptions, and these differences can be material. The experience we gain from actual mining or processing operations can also identify new or unexpected conditions that could reduce production below our current estimates, or increase our estimated capital or operating costs.If actual results fall below our current estimates, it could have a material adverse effect on our business, results of operations, financial condition and the Eldorado Gold share price.

Community Relations and Social License

Maintaining a positive relationship with the communities in which we operate is critical to continuing the successful operation of our existing projects and mines as well as the construction and development of existing and new projects and mines. As community support is a key component of a successful mining project or operation, Eldorado seeks to pursue ways to strategically integrate community support factors in our processes.

As a mining business, we may be expected to come under pressure in the jurisdictions in which we operate, or will operate in the future, to demonstrate that other affected parties (including employees, communities surrounding operations, indigenous rightsholders and the countries in which we operate) benefit and will continue to benefit from our commercial activities, and/or that we operate in a manner that will mitigate any potential damage or disruption to the interests of those parties. The evolving expectations related to human rights, indigenous rights, and environmental protections may also result in opposition to our current and future operations, the development of new projects and mines, and exploration activities. There is no assurance that we will be able to mitigate these risks, which could materially adversely affect our business, results of operations, financial condition and the Eldorado Gold share price.

Community relations are impacted by a number of factors, both within and outside of our control. Relations may be strained or social license lost by poor performance by the Company in areas such as health and safety, environmental impacts from the mine, increased traffic or noise, and other factors related to communications and interactions with various affected or interested groups. The Company expends significant financial and managerial resources to comply with various environmental, health and safety laws across various jurisdictions (including implementing safety protocols at sites, monitoring leading indicators, and emphasizing positive reinforcement). Despite these efforts, external factors such as press scrutiny or other distributed information about Eldorado specifically or extractive industries generally from media, governments, non-governmental organizations or interested individuals can also influence sentiment and perceptions toward the Company and its operations.

Surrounding communities may affect operations and projects through restriction of site access for equipment, supplies and personnel or through legal challenges. This could interfere with work on the Company's operations, and potentially pose a security threat to employees or equipment. Social license may also impact our permitting ability, Company reputation and our ability to build positive community relationships in exploration areas or around newly acquired properties. Such opposition may also take the form of legal or administrative proceedings or manifestations such as protests, roadblocks or other forms of public expression against our activities, and may have a negative impact on our local or global reputation and operations.

Erosion of social license or activities of third parties seeking to call into question social license may have the effect of slowing down the development of new projects and may increase the cost of constructing and operating these projects. Opposition by community and activist groups to our operations may require modification of, or preclude the operation or development of, our projects and mines or may require us to enter into agreements with such groups or local governments with respect to our projects and mines or exploration activities, in some cases, causing increased costs and significant delays to the advancement of our projects. Productivity may also be reduced due to restriction of access, requirements to respond to security threats or proceedings initiated or delays in permitting and there may also be extra costs

70

associated with improving the relationship between Eldorado and the surrounding communities. We seek to mitigate these risks through our commitment to operating in a socially responsible manner; however, there is no guarantee that our efforts in this respect will mitigate these risks.

In addition, governments in many jurisdictions where we operate, including Québec, must consult with local affected parties, including indigenous peoples, with respect to grants of mineral rights and the issuance or amendment of project authorizations. These requirements are subject to change from time to time. Eldorado supports consultation and engagement with local communities, and consultation and other rights of indigenous peoples which may require accommodations, including undertakings regarding financial compensation, employment, and other matters. This may affect our ability to acquire within a reasonable time frame effective mineral titles or environmental permits in these jurisdictions, including in some parts of Canada in which indigenous title is claimed, and may affect the timetable and costs of development of mineral properties in these jurisdictions. The risk of unforeseen claims or grievances by indigenous peoples also could affect existing operations as well as development projects and future acquisitions. These legal requirements and the risk of opposition by indigenous peoples may increase our operating costs and affect our ability to expand or transfer existing operations or to develop new projects.

Liquidity and Financing Risk

Liquidity risk is the risk that the Company cannot meet its planned and foreseeable commitments, including operating and capital expenditure requirements. We may be exposed to liquidity risks if we cannot maintain our cash positions, cash flows or mineral asset base, or appropriate financing is not available on terms satisfactory to us. In addition, we may be unable to secure loans and other credit facilities and sources of financing required to advance and support our business plans, including our plans to finance the Skouries Project. In the future, we may also be unable to maintain, renew or refinance our Notes, Fourth ARCA including any letters of credit issued in connection with the Fourth ARCA, or the Term Facility on terms we believe are favorable or at all.

The Company mitigates liquidity risk through the implementation of its capital management policy by spreading the maturity dates of investments over time, managing its capital expenditures and operational cash flows, and by maintaining adequate lines of credit and seeking external sources of funding where appropriate. Management uses a rigorous planning, budgeting and forecasting process to help determine the funds the Company will need to support ongoing operations and development plans. We have historically minimized financing risks by diversifying our funding sources, which include credit facilities, issuance of notes, issuance of flow-through shares, at-the-market equity programs and cash flow from operations. In addition, we believe that Eldorado Gold has the ability to access the public debt and equity markets given our asset base and current credit ratings; however, such market access may become restricted, and, if we are unable to access capital when required, it may have a material adverse effect on us.

Any decrease in production, or change in timing of production or the prices we realize for our gold, copper, or other metals, will directly affect the amount and timing of our cash flow from operations. A production shortfall or any of these other factors would change the timing of our projected cash flows and our ability to use the cash to fund capital expenditures, including spending for our projects. Failure to achieve estimates in production or costs could have an adverse impact on our future cash flow, business, results of operations, financial condition and the Eldorado Gold share price.

Management believes that the working capital at December 31, 2023, together with future cash flows from operations and access to the remaining undrawn revolving credit facility, in connection with the Fourth ARCA, the following issuance of letters of credit issued in support of the Term Facility, if required, are sufficient to support the Company's existing and foreseeable commitments for the next twelve months. However, if there are any material changes in the Company's assets or operations, including if actual results or capital requirements are different than expected, or financing, if required, is not available to the Company on terms satisfactory to meet these material changes, then this may adversely affect the ability of the Company to meet its financial obligations and operational and development plans. Unexpected economic and other crises have the potential to heighten liquidity risk, as Eldorado may be required to seek liquidity in a market beset by a sudden increase in the demand for liquidity and a simultaneous drop in supply.

Climate Change

We recognize that climate change is a global issue that has the potential to impact our operations, affected or interested parties and the communities in which we operate, which may result in physical risks and transition-related regulatory change risk. The continuing rise in global average temperatures has created varying changes to regional climates across the globe, resulting in risks to infrastructure, equipment and personnel. We face the possibility of increased costs to try to mitigate the negative effects of climate change. Governments at all levels are moving towards enacting legislation to address climate

71

change by regulating carbon emissions and energy efficiency, among other things. Where legislation has already been enacted, regulation regarding emission levels and energy efficiency are becoming more stringent. The mining industry, as a significant emitter of greenhouse gas emissions, is particularly exposed to these regulations. As a proactive measure, we are targeting a 30% mitigation in greenhouse gas emissions from 2020 emissions on a 'business as usual basis' by 2030 for currently operating mines, but our ability to effectively meet our target is subject to matters outside of our control, including being partially reliant on the decarbonization of the electrical grid in Greece. Furthermore, affected or interested parties, including shareholders, may increase demands for emissions reductions and call upon us or mining companies in general to better manage their consumption of climate-relevant resources (hydrocarbons, water, etc.). Costs associated with meeting these requirements may be subject to some offset by increased energy efficiency and technological innovation; however, there is no assurance that compliance with such legislation and/or affected party demands will not have an adverse effect on our business, results of operations, financial condition and the Eldorado Gold share price.

With respect to physical risks of climate change, the effects may include changing weather patterns, rising sea levels and increased frequency and intensity of extreme weather events such as floods, droughts, hurricanes, heat waves, tornadoes and wildfires, which have the potential to disrupt our operations and the transport routes we use. While all of our operations are exposed to physical risks from climate change, the anticipated effects are highly location specific. We have strived to identify such material risks over a short- to medium-timeframe (until 2030) using our enterprise risk management framework for each of our material properties to attempt to mitigate such risks. In Greece, increases in storm intensity, changes in rainfall patterns and amounts, increases in temperature, fires, water stress and drought are expected to be potential hazards for the Kassandra Mines (Olympias, Skouries and Stratoni) while pluvial flooding (flash flooding) is identified as an expected primary physical risk for Olympias and Stratoni presently. In Türkiye, heavy rains, flooding, drought, wind events and wildfires are expected to be potential hazards. At Kışladağ, the risks are expected to be related to severe precipitation events or precipitation induced landslides, and their impact on water levels and site infrastructure. In 2023, heavy rains resulted in unanticipated impacts on heap leaching operations at Kışladağ.The increased precipitation selectively mobilized fine particles which created variability in permeability and in turn lead to an increase in metal inventory in the leach facility. The increased precipitation percolated through the heap and was captured in the solution ponds as anticipated. The additional water diluted solution tenor, which will be reprocessed and consumed as part of normal operations. At Efemçukuru, flash flooding caused by severe precipitation events and wildfires are identified as expected risks. Lastly, at Lamaque, increased ice storms or black ice conditions which may impact exterior equipment and infrastructure, including electrical infrastructure, along with high wind events and warming winters, are identified as expected risks. In light of several wildfires that occurred at Lamaque in 2023, we expect that wildfires may continue to be a potential hazard in the area going forward. See also “Foreign Operations”.

Such physical risks or events can temporarily slow or halt operations due to physical damage to assets, reduced worker productivity for safety protocols on site related to extreme temperatures or lightening events, worker aviation and bus transport to or from the site, and local or global supply route disruptions that may limit transport of essential materials, chemicals and supplies. Where appropriate, our facilities have developed emergency plans for managing extreme weather conditions; however, extended disruptions could result in interruption to production and deliveries to buyers which may adversely affect our business, results of operations, financial condition and the Eldorado Gold share price. Our facilities depend on regular and steady supplies of consumables (water, diesel fuel, chemical reagents, etc.) to operate efficiently. Our operations also rely on the availability of energy from public power grids, which may be put under stress due to extremes in temperatures, or face service interruptions due to more extreme weather and climate events. Changing climate patterns may also affect the availability of water. If the effects of climate change cause prolonged disruption to the delivery of essential commodities or our product, or otherwise effect the availability of essential commodities, or affect the prices of these commodities, then our production efficiency may be reduced which may have adverse effects on our business, results of operations, financial condition and the Eldorado Gold share price.

With respect to transition-related regulatory changes, the effects may include the financial impact of carbon pricing regulations if and when Eldorado's operating sites are affected by such regulations, managing fuel and electricity costs and incentives for adopting low-carbon technologies, insurance premiums associated with weather events and emissions intensities, access to capital for advancing and funding low carbon mining operations and projects, accessing sustainability-linked capital and managing regulatory compliance and corporate reputation related to evolving governmental and societal expectations. Such effects may have an adverse effect on our business, results of operations, financial condition and the Eldorado Gold share price.

Inflation Risk

General inflationary pressures may affect our labour, commodity and other input costs, which could have a material adverse effect on our financial condition, results of operations and the capital expenditures required for the development and operation of Eldorado's projects. Specifically, labour costs at Kışladağ

72

and Efemçukuru increased in line with commitments under our collective bargaining agreement. We recognize that a need to support our workforce as they face rising costs of food and electricity may impact collective bargaining agreements and labour costs in the future. Labour costs are denominated in local currency and, if the Turkish Lira does not correspondingly weaken against the U.S. dollar , cost increases may not be offset by currency movements. We continue to monitor the impacts of cost inflation on our operations. Certain emerging markets in which we operate, or may in the future operate, have experienced fluctuating rates of inflation. For example, Türkiye's annual consumer inflation rate year-on-year rose to 64.77% in December 2023, and to 64.86% in January 2024. There can be no assurance that any governmental action will be taken to control inflationary or deflationary cycles, that any governmental action taken will be effective, or whether any governmental action may contribute to economic uncertainty. Governmental action to address inflation or deflation may also affect currency values. Accordingly, inflation and any governmental response thereto may have a material adverse effect on our business, results of operations, financial condition and the Eldorado Gold share price.

Environmental

Although we monitor our sites for potential environmental hazards, there is no assurance that we have detected, or can detect all possible risks to the environment arising from our business and operations. We expend significant resources to comply with environmental laws, regulations and permitting requirements, and we expect to continue to do so in the future. The failure to comply with applicable environmental laws, regulations and permitting requirements may result in injunctions, damages, suspension or revocation of permits and imposition of penalties, as well as a loss event in excess of insurance coverage and reputational damage. There is no assurance that:

•we have been or will be at all times in complete compliance with such laws, regulations and permitting requirements, or with any new or amended laws, regulations and permitting requirements that may be imposed from time to time;

•our compliance will not be challenged; or

•the costs of compliance will be economic and will not materially or adversely affect our future cash flow, results of operations and financial condition.

We may be subject to proceedings (and our employees subject to criminal charges in certain jurisdictions) in respect of alleged failures to comply with increasingly strict environmental laws, regulations or permitting requirements or of posing a threat to or of having caused hazards or damage to the environment or to persons or property. While any such proceedings are in process, we could suffer delays or impediments to or suspension of development and construction of our projects and operations and, even if we are ultimately successful, we may not be compensated for the losses resulting from any such proceedings or delays.

There may be existing environmental hazards, contamination or damage at our mines or projects that we are unaware of. We may also be held responsible for addressing environmental hazards, contamination or damage caused by current or former activities at our mines or projects or exposure to hazardous substances, regardless of whether or not hazard, damage, contamination or exposure was caused by our activities or by previous owners or operators of the property, past or present owners of adjacent properties or by natural conditions and whether or not such hazard, damage, contamination or exposure was unknown or undetectable.

Any finding of liability in such proceedings could result in additional substantial costs, delays in the exploration, development and operation of our properties and other penalties and liabilities related to associated losses, including, but not limited to:

•monetary penalties (including fines);

•restrictions on or suspension of our activities;

•loss of our rights, permits and property, including loss of our ability to operate in that country or generally;

•completion of extensive remedial cleanup or paying for government or third-party remedial cleanup;

•premature reclamation of our operating sites; and

•seizure of funds or forfeiture of bonds.

The costs of complying with any orders made or any cleanup required and related liabilities from such proceedings or events may be significant and could have a material adverse effect on our business, results of operations, financial condition and the Eldorado Gold share price.

We are not able to determine the specific impact that future changes in environmental, health and safety laws, regulations and industry standards may have on our operations and activities, and our resulting

73

financial position; however, we anticipate that capital expenditures and operating expenses will increase in the future as a result of the implementation of new and increasingly stringent environmental, health and safety laws, regulations and industry standards. For example, emissions standards for carbon dioxide and sulphur dioxide are becoming increasingly stringent, as are laws relating to the use and production of regulated chemical substances and the consumption of water by industrial activities. Further changes in environmental, health and safety laws, regulations and industry standards, new information on existing environmental, health and safety conditions or other events, including legal proceedings based upon such conditions, or an inability to obtain necessary permits, could require increased financial reserves or compliance expenditures, or otherwise have a material adverse effect on Eldorado. Changes in environmental, health and safety laws, regulations and industry standards could also have a material adverse effect on product demand, product quality and methods of production, processing and distribution. In the event that any of our products were demonstrated to have negative health effects, we could be exposed to workers' compensation and product liability claims, which could have a material adverse effect on our business, results of operations, financial condition and the Eldorado Gold share price. See also “Waste Disposal”.

On May 27, 2021, the Ministry of Industry and Information Technology of the People's Republic of China issued YS/T 3004-2021 – Gold Industry Standard of People's Republic of China (the "Industry Standard") which was implemented on October 1, 2021. When imported in China, gold concentrates that comply with the Industry Standard are cleared under tariff number HS 2616 9000.01 and are exempt from import charges, whereas all other gold concentrates are declared under tariff number HS 2616 9000.09 and a VAT charge of 13% is imposed. Olympias gold concentrates do not fall within the scope of the Industry Standard due to the level of arsenic contained therein and therefore have been declared under tariff number HS 2616 9000.09 since October 1, 2021 upon importation from China as subject to a 13% VAT import charge. Although we are exploring other markets and addressing this change in our commercial agreements on a bilateral basis to minimize the effect, approximately 35% of Olympias sales are expected to be subject to the 13% VAT charge going forward and there can be no assurance that the effects of the Industry Standard will not have a material adverse effect on Eldorado’s business, results of operations and financial condition.

Production and Processing

Estimates of total future production and costs for our mining operations are based on our LOM plans. These estimates can change, or we might not achieve them, which could have a material adverse effect on any or all of our future cash flow, business, results of operations, financial condition and the Eldorado Gold share price.

Our plans are based on, among other things, our mining experience, reserve estimates, assumptions about ground conditions and physical characteristics of ores (such as hardness and the presence or absence of certain metallurgical characteristics, including the presence of materials that may adversely affect the ability to process, export and sell our products) and estimated rates and costs of production. Our actual production and costs may be significantly different from our estimates for a variety of reasons, including the risks and hazards discussed elsewhere as well as unfavorable operating conditions or external events impacting operations, including:

•actual ore mined varying from estimates in grade, tonnage and mineralogical and other characteristics;

•industrial accidents, environmental incidents and natural phenomena, including discharge of metals, concentrates, pollutants or hazardous materials;

•seepage from tailings or other storage facilities or ponds;

•failure of mining pit slopes, waste rock storage facility and tailings impoundment walls, other water storage structures and heap leach structures;

•surface or underground fires, floods, landslides or ground subsidence;

•changes in power supply and costs and potential power shortages;

•imposition of a moratorium on our operations;

•impact of the disposition of mineral assets;

•shortages and timing delays, of principal supplies and equipment needed for operation, including explosives, fuels, chemical reagents, water, equipment parts and lubricants;

•failure of unproven or evolving technologies or loss of information integrity or data;

•unexpected geological, geochemical and water (ground and surface) conditions;

•variable metallurgical conditions and metal recovery;

•insufficient capacity for disposal of waste materials from our operations;

•unanticipated changes in inventory levels at heap-leach operations;

•fall-of-ground accidents in underground operations;

•seismic activity;

74

•renewal of required permits and licenses;

•litigation;

•shipping interruptions or delays;

•management of the mining process, including revisions to mine plans;

•unplanned maintenance and reliability;

•unexpected work stoppages or labour costs, shortages or strikes;

•security incidents;

•general inflationary pressures;

•currency exchange rates;

•the presence of valuable by-products such as copper (which can be crucial in offsetting the costs of gold production); and

•changes in law, regulation or policy.

The occurrence of one or more of these events in connection with our exploration activities, development and production and closure of mining operations may result in the death of, or personal injury to, our employees, other personnel or third parties, the loss of mining equipment, damage to or destruction of mineral properties, production facilities or property belonging to us or others, monetary losses, environmental damage and potential legal liabilities. In addition, the occurrence of one or more of the events listed above may result in a less than optimal operation and lower throughput or lower recovery, as well as interruptions, deferral or unanticipated fluctuations in production.This could cause a mineral deposit to become unprofitable, even if it was mined profitably in the past.Although we review and assess the risks related to extraction and seek to put appropriate mitigating measures in place, there is no assurance that we have foreseen and/or accounted for every possible factor that might impact operations, production and processing.The occurrence of one or more of these events could therefore have a material adverse effect on our business, results of operations, financial condition and the Eldorado Gold share price. See also“Environmental”, “Waste Disposal”, and “Geotechnical Considerations”.

With respect to changes in power supply and costs and potential power shortages, our operations in Türkiye and Greece have been experiencing recent energy supply issues affecting the price and supply of gas, oil and electricity used in our operations, which has caused increased energy prices and decreased energy supply. A sustained increase in energy prices, or a sustained decrease in energy supply, could have a material adverse effect on Eldorado’s business, results of operations, financial condition and the Eldorado Gold share price.

A number of factors could affect our ability to process ore in the tonnages we have budgeted, the quantities of the metals or deleterious materials that we recover and our ability to efficiently handle material in the volumes budgeted, including, but not limited to the presence of oversize material at the crushing stage; material showing breakage characteristics different to those planned; and material with grades outside of planned grade range, among others.

Our operations at Kışladağ involve the heap leaching process. The heap leaching process, while not as capital intensive as the more conventional milling process, involves uncertainties associated with the chemical and physical processes included in leaching, which can impact ultimate recoveries or leach cycle times required to achieve the ultimate recovery. While recent circuit additions of the high pressure grinding rolls and agglomeration are expected to support a higher circuit recovery, there is no assurance that this circuit will continue to perform in accordance with our expectations. See also “Climate Change”.

Some of our processing operations rely on the use of sodium cyanide to extract gold and silver from ore. As a result of rising energy prices and other factors, there has been an increase in sodium cyanide prices and, further, large sodium cyanide suppliers have substantially lowered or ceased production temporarily, particularly in Europe, causing a supply shortage for sodium cyanide. A sustained increase in sodium cyanide prices, or a sustained supply shortage thereof, could have a material adverse effect on Eldorado’s business, results of operations, financial condition and the Eldorado Gold share price.

The occurrence of any of the above could affect our ability to treat the number of tonnes planned, recover valuable materials, remove deleterious materials and process ore, concentrate and tailings as planned. This may result in lower throughput, lower recoveries, lower product qualities, more downtime or some combination of all four. While minor issues of this nature are part of normal operations, more issues may arise than anticipated, which may have an adverse effect on our future cash flow, results of operations and financial condition.

Waste Disposal

The water collection, treatment and disposal operations at the Company's mines are subject to substantial regulation and involve significant environmental risks. The extraction process for gold and metals can

75

produce tailings. Tailings are the process waste generated once grinding and extraction of gold or other metals from the ore is completed in the milling process, which are stored in engineered facilities designed, constructed, operated and closed in conformance with local requirements and best practices. Tailings may be filtered and dried for placement in a surface facility or mixed with cement (and potentially other waste material) and used underground as structural fill. A number of factors can affect our ability to successfully dispose of waste material in the form that is optimal for our operations, including, but not limited to:

•access to suitable locations due to permitting, operational or other restrictions;

•requirements to encapsulate acid-generating or other hazardarous material;

•milled material being ground too fine and requiring further treatment; and

•sufficient infrastructure required to place material underground in the right locations.

If issues with any of the above items occur, the normal discharge or placement process may be affected, requiring us to alter existing plans. While minor issues of this nature are part of normal operations, more issues may arise than anticipated, which could have an adverse effect on our business, results of operations, financial condition and the Eldorado Gold share price.

The Company operates its tailings facilities to TSM guidelines and aligns with the Canadian Dam Association standards. The Company operates active dry stack tailings facilities at the Efemçukuru operation in Türkiye (designated as the Efemçukuru TMF) and at the Olympias operation in Greece (designated as the Kokkinolakkas TMF).

Lamaque contains three slurried tailings facilities. Tailings are currently being deposited at the tailings facility located adjacent to the Sigma mill, designated as the Sigma Tailings Management Facility.A second TMF is located at the Aurbel site, designated as the Aurbel TMF. The third tailings facility is located within the operational area of Lamaque, designated as the Lamaque TMF. No tailings are currently being deposited to the Aurbel TMF or Lamaque TMF.

In 2021, Eldorado established an ITRB to provide technical guidance on design and operational practices at its tailings facilities. Independent reviews of all tailings facilities are completed on a regular basis.

Although the Company has established the ITRB and conducts extensive maintenance and monitoring, engages external consultants and incurs significant costs to maintain the Company's operations, equipment and infrastructure, including tailings management facilities (including, without limitation, those tailings facilities, both active and inactive, associated with Eldorado's operations in Türkiye, Greece and Quebec), unanticipated failures or damage, insufficient equipment or infrastructure, as well as changes to laws and regulations may occur that could cause injuries, production loss, environmental pollution, a loss event in excess of insurance coverage, reputational damage or other materially adverse effects on the Company's operations and financial condition resulting in significant monetary losses, restrictions on operations and/or legal liability.

A major spill, failure or material flow from the tailings facilities (including through occurrences beyond the Company's control such as extreme weather, seismic event, or other incident) may cause damage to the environment and the surrounding communities. Poor design or poor maintenance of the tailings impoundment structures or improper management of site water may contribute to structural failure or tailings release and could also result in damage or injury. Failure to comply with existing or new environmental, health and safety laws and regulations may result in injunctions, fines, suspension or revocation of permits and other penalties. The costs and delays associated with compliance with these laws, regulations and permits could prevent the Company from proceeding with the development of a project or the operation or further development of a mine or increase the costs of development or production and may materially adversely affect the Company's business, results of operations, financial condition and the Eldorado Gold share price. The Company may also be held responsible for the costs of investigating and addressing contamination (including claims for natural resource damages) or for fines or penalties from governmental authorities relating to contamination issues at current or former sites, either owned directly or by third parties. The Company could also be held liable for claims relating to exposure to hazardous and toxic substances and major spills or failure of the tailing facilities, which could include a breach of a tailings impoundment. The costs associated with such responsibilities and liabilities may be significant, be higher than estimated and involve a lengthy clean-up. Moreover, in the event that the Company is deemed liable for any damage caused by a major spill, failure or material flow from the tailings facilities (including through occurrences beyond the Company's control such as extreme weather, a seismic event, or other incident), the Company's losses or the consequences of regulatory action might exceed insurance coverage. Should the Company be unable to fully fund the cost of remedying such environmental concerns, the Company may be required to suspend operations temporarily or permanently. Such incidents could also have a negative impact on the reputation and image of the Company.

Geotechnical Considerations

Throughout the mining industry, operational conditions continue to get more challenging, with the need to mine increasingly variable and deep deposits increasing exposure to seismic activity, geotechnical complexity and hydrogeological uncertainty. Although adequate precautions to minimize risk will be taken, unanticipated adverse conditions may occur and may be difficult to predict.

Geotechnical challenges can also be observed in surface facilities such as:

•heap leach pads;

•water management structures and ponds;

•waste rock storage areas;

•tailings storage areas (both slurried and dry); and

•open pit operations.

Adverse and variable conditions may occur and may be affected by risks and hazards outside of our control, and may result in sudden or unpredicted movement of material, including slips or other failures in heap leach pads, waste rock storage areas or open pits, containment discharges and leakage of leaching solutions. Such events may not be detected in advance and all of which could have a material adverse effect on our business, results of operations, financial condition and the Eldorado Gold share price. See also “Environmental”, “Waste Disposal”, and “Production and Processing”.

Global Economic Environment

Market events and conditions, including disruptions in the international credit markets and other financial systems and deteriorating global economic conditions, could increase the cost of capital or impede our access to capital.

Economic and geopolitical events may create uncertainty in global financial and equity markets. The global debt situation may cause increased global political and financial instability resulting in downward price pressure for many asset classes and increased volatility and risk spreads.

For example, on February 24, 2022, Russian military forces launched a full-scale military invasion of Ukraine. In response, Ukrainian military personal and civilians are actively resisting the invasion. Many countries throughout the world have provided aid to Ukraine in the form of financial aid and in some cases military equipment and weapons to assist in their resistance to the Russian invasion. The North Atlantic Treaty Organization (“NATO”) has also mobilized forces to NATO member countries that are close to the conflict as deterrence to further Russian aggression in the region. The outcome of the conflict is uncertain and is likely to have wide ranging consequences on the peace and stability of the region, the availability and price of commodities produced in the region (e.g. hydrocarbons) and the world economy. Certain countries, including Canada and the United States, have imposed strict financial and trade sanctions against Russia and such sanctions may have far reaching effects on the global economy. As Russia is a major exporter of oil and natural gas, any disruption of supply of oil and natural gas from Russia could cause a significant worldwide supply shortage of oil and natural gas and significantly impact pricing of oil and gas worldwide. A lack of supply and high prices of oil and natural gas could also have a significant adverse impact on the world economy. The long-term impacts of the conflict and the sanctions imposed on Russia remain uncertain.

These and other impacts of the Russia-Ukraine conflict or other armed conflict could also have the effect of heightening many of the other risks described in this “Risk Factors in Our Business” section, including the risk factor titled “Limited Number of Smelters and Off-Takers”. The ultimate impact of the Russia-Ukraine conflict on our business is difficult to predict and depends on factors that are evolving and beyond our control, including the scope and duration of the conflict, as well as actions taken by governmental authorities and third parties in response. We may experience material adverse impacts to our business, results of operations, financial condition and the Eldorado Gold share price as a result of any of these disruptions, even after the Russia-Ukraine conflict has subsided.

Such disruptions could make it more difficult for us to obtain capital and financing for our operations, or increase the cost of it, among other things.

If such negative economic conditions persist or worsen, it could lead to increased political and financial uncertainty, which could result in regime or regulatory changes in the jurisdictions in which we operate. High levels of volatility and market turmoil could have an adverse effect on our business, results of operations, financial condition and the Eldorado Gold share price.

77

Pandemics, Epidemics and Public Health Crises

The occurrence or reoccurrence of any pandemic, epidemic, endemic or similar public health threats (such as COVID-19) and resulting negative impact on the global economy and financial markets, the duration and extent of which is highly uncertain and could be material, may have an adverse impact on our business, results of operations, financial condition and the Eldorado Gold share price.

The extent to which global pandemics impact our business going forward will depend on a variety of factors including directives of government and public health authorities; disruptions and volatility in the global capital markets, which may increase cost of capital and adversely impact access to capital; impacts on workforces throughout the regions in which we operate, which may result in our workforce being unable to work effectively, including because of illness, quarantines, government actions, facility closures or other restrictions in connection with such pandemics; the roll out and effectiveness of vaccines or other treatments; delays in product refining and smelting due to restrictions or temporary closures; sustained disruptions in global supply chains; and other unpredictable impacts that are not foreseeable at this time. These and other impacts of a pandemic, epidemic, endemic or similar public health threats could also have the effect of heightening many of the other risks described in this "Risk Factors in Our Business" section.

Limited Number of Smelters and Off-Takers

We rely on a limited number of smelters and off-takers to produce and distribute the product of our operations, a substantial number of which are in China. The amount of gold and other concentrates that we can produce and sell is subject to the accessibility, availability, proximity, and capacity of the smelters and off-takers to produce and distribute the product of our operations. A lack of smelter capacity to process Eldorado's gold and other concentrates, in China and elsewhere, whether as a result of environmental, health and safety laws, regulations and industry standards or otherwise, could limit the ability for Eldorado to deliver its products to market. In addition, the Industry Standard could result in Eldorado's inability to realize the full economic potential of certain of its products or in a reduction of the price offered for certain of Eldorado's gold concentrates. In addition, our ability to transport concentrate to smelters may be affected by geo-political considerations, including the Russia-Ukraine war and more recent developments involving threats to the safety and security of commercial shipping operations in the Red Sea. Unexpected shut-downs, concentrate transportation challenges or unavailability of smelter capacity, because of actions taken by regulators or otherwise, could have a material adverse effect on Eldorado's business, results of operations, financial condition and the Eldorado Gold share price. See also "Russia-Ukraine Conflict" and “Foreign Operations”.

Labour - Employee/Union Relations/Greek Transformation

We depend on our workforce to explore for mineral reserves and resources, develop our projects and operate our mines. We have programs to recruit and train the necessary workforce for our operations, and we work hard at maintaining good relations with our workforce to minimize the possibility of defections and strikes, lockouts (if permitted under applicable legislation) and other stoppages at our work sites. In addition, our relations with our employees may be affected by changes in labour and employment legislation that may be introduced by the relevant governmental authorities in whose jurisdictions we carry on business. Changes in such legislation or a prolonged labour disruption or shortages at any of our mines or projects could have a material adverse effect on our results of operations, financial condition and the Eldorado Gold share price.

A significant portion of our employees are represented by labour unions in a number of countries under various collective bargaining agreements with varying durations and expiration dates. Labour agreements are negotiated on a periodic basis, and may not be renewed on reasonably satisfactory terms to us or at all. If we do not successfully negotiate new collective bargaining agreements with our union workers, we may incur prolonged strikes and other work stoppages at our mining operations, which could have a material adverse effect on our business, results of operations, financial condition and the Eldorado Gold share price. Additionally, if we enter into a new labour agreement with any union that significantly increases our labour costs relative to our competitors, our ability to compete may be materially and adversely affected. We expect that labour shortages and industry dynamics that are beyond our control could contribute to growing shortages of skilled labour, with the possibility of negative impacts on our ability to develop or operate various projects.

We could experience labour disruptions such as work stoppages, work slowdowns, union organizing campaigns, strikes, or lockouts (if permitted under applicable legislation) that could adversely affect our operations.For example, we are undertaking a significant transformation process in Greece to improve the performance of the operating Kassandra Mines, in respect of which work stoppages of a significant duration are possible as we move forward to achieve the necessary outcomes of this work. Any work interruptions involving Eldorado's employees (including as a result of a strike or lockout as permitted by

78

applicable legislation) or operations, or any jointly owned facilities operated by another entity present a significant risk to Eldorado and could have a material adverse effect on Eldorado's business, financial condition, and results of operations. See also "Skilled Workforce” and “Inflation Risk”.

Employee Misconduct

We are reliant on the good character of our employees and are subject to the risk that employee misconduct could occur. Although we take precautions to prevent and detect employee misconduct, these precautions may not be effective and the Company could be exposed to unknown and unmanaged risks or losses. The existence of our Code of Ethics and Business Conduct, among other governance and compliance policies and processes, may not prevent incidents of theft, dishonesty or other fraudulent behaviour nor can we guarantee compliance with legal and regulatory requirements.

These types of misconduct could result in unknown and unmanaged damage or losses, including regulatory sanctions and serious harm to our reputation. The precautions we take to prevent and detect these activities may not be effective. If material employee misconduct does occur, our business, results of operations, financial condition and the Eldorado Gold share price could be adversely affected.

Key Personnel

We depend on a number of key personnel, including executives and senior officers. We do not have key person life insurance. Employment contracts are in place with each of these executives, however, losing any of them could have an adverse effect on our operations.

We need to continue implementing and enhancing our management systems and recruiting and training new employees to manage our business effectively. We have been successful in attracting and retaining skilled and experienced personnel in the past, and expect to be in the future, but there is no assurance this will be the case.

Skilled Workforce

We depend on a skilled workforce, including but not limited to mining and mineral, metallurgical and geological engineers, geologists, environmental and safety specialists, and mining operators to explore and develop our projects and operate our mines. We have programs and initiatives in place to attract and retain a skilled workforce. However, we are potentially faced with a shortage of skilled professionals due to competition in the industry and as experienced employees continue to exit the workforce. As such, we need to continue to enhance training and development programs for current employees and partner with local universities and technical schools to train and develop a skilled workforce for the future, such efforts are costly and there is no assurance that they will result in Eldorado having the workforce it needs, including in terms of location, skill set and timing. See also "Labour - Employee/Union Relations/Greek Transformation” and “Inflation Risk”.

Expatriates

We depend on expatriates to work at our mines and projects to fill gaps in expertise and provide needed management skills in the countries where we operate. Additionally, we depend on expatriates to transfer knowledge and best practices and to train and develop in-country personnel and transition successors into their roles. Such training requires access to our sites and such access may be prohibited by government. We operate in challenging locations and must continue to maintain competitive compensation and benefits programs to attract and retain expatriate personnel. We must also develop in-country personnel to run our mines in the future. A lack of appropriately skilled and experienced personnel in key management positions would have an adverse effect on our operations.

Contractors

We may engage a number of different contractors during the development and construction phase of a project, including pursuant to a lump sum contract for specified services or through a range of engineering, procurement, construction and management contract options, depending on the type and complexity of work that is being undertaken, and the level of engineering that has been completed when the contract is awarded. Depending on the type of contract and the point at which it is awarded, there is potential for variations to occur within the contract scope, which could take the form of extras that were not considered as part of the original scope or change orders. These changes may result in increased capital costs. Similarly, we may be subject to disputes with contractors on contract interpretation, which could result in increased capital costs under the contract or delay in completion of the project if a contract dispute interferes with the contractor's efforts on the ground. There is also a risk that our contractors and

79

subcontractors could experience labour disputes or become insolvent, and this could have an adverse effect on our business, results of operations, financial condition and the Eldorado Gold share price.

Indebtedness

As at December 31, 2023, we have approximately $636 M in total debt. The incurrence or maintenance of substantial levels of debt could adversely affect our business, results of operations, financial condition, the Eldorado Gold share price and our ability to take advantage of corporate opportunities.

Long term indebtedness could have adverse consequences, including:

•limiting our ability to obtain additional financing to fund future working capital, capital expenditures, acquisitions or other general corporate requirements, or requiring us to make non-strategic divestitures;

•requiring a substantial portion of our cash flows to be dedicated to debt service payments instead of other purposes, thereby reducing the amount of cash flows available for working capital, capital expenditures, acquisitions, dividends and other general corporate purposes;

•increasing our vulnerability to general adverse economic and industry conditions;

•limiting our flexibility in planning for and reacting to changes in the industry in which we compete;

•placing us at a disadvantage compared to other, less leveraged competitors;

•increasing our cost of borrowing; and

•putting us at risk of default if we do not service or repay this debt in accordance with applicable covenants.

While neither our articles nor our by-laws limit the amount of indebtedness that we may incur, the level of our indebtedness under our Notes, Fourth ARCA, and Term Facility from time to time could impair our ability to obtain additional financing in the future on a timely basis, or at all, and to take advantage of business opportunities that may arise, thereby potentially limiting our operational flexibility as well as our financial flexibility.

Current and Future Operating Restrictions

Our Notes, Fourth ARCA, and the Term Facility contain certain restrictive covenants that impose significant operating and financial restrictions on us. In some circumstances, the restrictive covenants may limit our operating flexibility and our ability to engage in actions that may be in our long-term best interest, including, among other things, restrictions on our ability to:

•incur additional indebtedness and guarantee indebtedness;

•pay dividends or make other distributions or repurchase or redeem our capital stock;

•prepay, redeem or repurchase certain debt;

•make loans and investments, including investments into certain affiliates;

•sell, transfer or otherwise dispose of assets;

•incur certain lease obligations;

•incur or permit to exist certain liens;

•enter into transactions with affiliates;

•undertake certain acquisitions;

•complete certain corporate changes;

•enter into certain hedging arrangements;

•enter into agreements restricting our subsidiaries' ability to pay dividends; and

•consolidate, amalgamate, merge or sell all or substantially all of our assets.

In addition, the restrictive covenants in our Fourth ARCA and Term Facility contain certain restrictions on us and require us to maintain specified financial ratios and satisfy other financial condition tests. Our ability to meet those financial ratios and tests may be affected by events beyond our control. These restrictions could limit our ability to obtain future financing, make acquisitions, grow in accordance with our strategy or secure the needed working capital to withstand future downturns in our business or the economy in general, or otherwise take advantage of business opportunities that may arise, any of which could place us at a competitive disadvantage relative to our competitors that may have less debt and are not subject to such restrictions. Failure to meet these conditions and tests could constitute events of default thereunder.

80

Change of Control

Upon the occurrence of specific kinds of change of control events, we will be required to offer to repurchase all outstanding Notes at 101% of their principal amount, plus accrued and unpaid interest, if any, to the repurchase date. Additionally, under the Fourth ARCA, a change of control (as defined therein) will constitute an event of default that permits the lenders to accelerate the maturity of borrowings under the credit agreement and terminate their commitments to lend.

The source of funds for any purchase of the Notes and repayment of borrowings under the Fourth ARCA would be our available cash or cash generated from our subsidiaries' operations or other sources, including borrowings, sales of assets or sales of equity, as applicable. We may not be able to repurchase the Notes or repay the Fourth ARCA upon a change of control because we may not have sufficient financial resources to purchase all of the debt securities that are tendered upon a change of control and repay any of our other indebtedness that may become due. We may require additional financing from third parties to fund any such purchases, and we may be unable to obtain financing on satisfactory terms or at all. Further, our ability to repurchase the Notes may be limited by law. In order to avoid the obligations to repurchase the Notes and events of default and potential breaches of the Fourth ARCA, we may have to avoid certain change of control transactions that would otherwise be beneficial to us.

Debt Service Obligations

Our ability to make scheduled payments on, refinance or commence repayment of our debt obligations depends on our financial condition and operating performance, which are subject to prevailing economic and competitive conditions and to certain financial, business, legislative, regulatory and other factors beyond our control, including those identified elsewhere in this AIF. We may be unable to maintain a level of cash flows from operating activities sufficient to permit us to pay the principal, premium, if any, and interest on our indebtedness.

If our cash flows and capital resources are insufficient to fund our debt service obligations, we could face substantial liquidity problems and could be forced to reduce or delay investments and capital expenditures or to dispose of material assets or operations, seek additional debt or equity capital or restructure or refinance our indebtedness.

We may be unable to commence repayment, as planned. We may also not be able to effect any such alternative measures, if necessary, on commercially reasonable terms or at all and, even if successful, those alternatives may not allow us to meet our scheduled debt service obligations. The Notes and Fourth ARCA will restrict our ability to dispose of certain assets and use the proceeds from those dispositions other than to repay such obligations and may also restrict our ability to raise debt or equity capital to be used to repay other indebtedness when it becomes due. We may not be able to consummate those dispositions or to obtain proceeds in an amount sufficient to meet any debt service obligations then due.

In addition, Eldorado Gold conducts substantially all of its operations through its subsidiaries. Accordingly, repayment of Eldorado Gold's indebtedness will be dependent in large measure on the generation of cash flow by its subsidiaries and their ability to make such cash available to Eldorado Gold, by dividend, intercompany debt repayment or otherwise. Unless they are or become guarantors of Eldorado Gold's indebtedness, Eldorado Gold's subsidiaries do not have any obligation to pay amounts due on its indebtedness or to make funds available for that purpose. Eldorado Gold's subsidiaries may not be able to, or may not be permitted to, make distributions to enable Eldorado Gold to make payments in respect of its indebtedness. In addition, certain subsidiaries of Eldorado Gold may not be able to, or may not be permitted to, make certain investments into certain other subsidiaries of Eldorado Gold beyond a certain threshold amount. Each subsidiary is a distinct legal entity, and, under certain circumstances, legal and contractual restrictions may limit Eldorado Gold's ability to obtain cash from its subsidiaries. While the Notes and Fourth ARCA limit the ability of Eldorado Gold's subsidiaries to incur consensual restrictions on their ability to pay dividends or make other intercompany payments to Eldorado Gold, these limitations are subject to qualifications and exceptions. Furthermore, as Eldorado's funds are used to develop projects in foreign jurisdictions through foreign subsidiaries, there may be restrictions on foreign subsidiaries' ability to pay dividends or make other intercompany payments to Eldorado Gold. In the event that Eldorado Gold does not receive distributions from its subsidiaries, Eldorado Gold may be unable to make required principal and interest payments on its indebtedness, including the Notes and Fourth ARCA.

Our inability to generate sufficient cash flows to satisfy our debt obligations, or to refinance our indebtedness on commercially reasonable terms or at all, would materially and adversely affect our financial position, results of operations and our ability to satisfy our obligations and our debt instruments.

81

Default on Obligations

A breach of the covenants under the Notes, Fourth ARCA, the Term Facility or our other debt instruments could result in an event of default under the applicable indebtedness. Such a default may allow the creditors to accelerate the repayment of the related debt and may result in the acceleration of repayment of any other debt to which a cross-acceleration or cross-default provision applies. In addition, an event of default under the Fourth ARCA would permit the lenders thereunder to terminate all commitments to extend further credit under that facility. Furthermore, if we are unable to repay any amounts due and payable under the Fourth ARCA, those lenders could proceed against the collateral granted to them to secure such indebtedness. If our lenders or noteholders accelerate the repayment of our borrowings, we may not have sufficient assets to repay that indebtedness.

If we are unable to generate sufficient cash flow and are otherwise unable to obtain funds necessary to meet required payments of principal, premium, if any, and interest on our indebtedness, or if we otherwise fail to comply with the various covenants in our debt instruments, which could cause cross-acceleration or cross-default under other debt agreements, we could be in default under the terms of the agreements governing such other indebtedness. If such a default occurs:

•the holders of the indebtedness may be able to cause all of our available cash flow to be used to pay the indebtedness and, in any event, could elect to declare all the funds borrowed thereunder to be due and payable, together with accrued and unpaid interest; or

•we could be forced into bankruptcy, liquidation or restructuring proceedings.

If our operating performance declines, we may in the future need to amend or modify the agreements governing our indebtedness or seek concessions from the holders of such indebtedness. There is no assurance that such concessions would be forthcoming.

Credit Ratings

Our outstanding Notes currently have a non-investment grade credit rating and any rating assigned could be lowered or withdrawn entirely by a rating agency if, in that agency's judgment, future circumstances relating to the basis of the credit rating, such as adverse changes to our business or affairs, so warrant. Consequently, real or anticipated changes in our credit ratings will generally affect the market value of the Notes.Additionally, credit ratings may not reflect the potential effect of risks relating to the Notes. Any future lowering of our ratings may make it more difficult or more expensive for us to obtain additional financing. In 2023, there were no changes to the credit ratings provided by S&P, Moody's, or Fitch.

Government Regulation

The mineral exploration, development, mining, and processing activities of Eldorado in the countries where we operate are subject to various laws governing a wide range of matters, including, but not limited to, the following:

•the environment, including land and water use;

•the right to conduct our business, including limitations on our rights in jurisdictions where we are considered a foreign entity and restrictions on inbound investment;

•prospecting and exploration rights and methods;

•development activities;

•construction;

•mineral production;

•reclamation;

•royalties, taxes, fees and imposts;

•importation of goods;

•currency exchange restrictions;

•sales of our products;

•repatriation of profits and return of capital;

•immigration (including entry visas and employment of our personnel);

•labour standards and occupational health

•supply chain transparency (including Canada’s Modern Slavery Act);

•mine safety;

•use of toxic substances;

•mineral title, mineral tenure and competing land claims; and

•impacts on and participation rights of local communities and entities.

82

Although we believe our mineral exploration, development, mining, and processing activities are currently carried out in accordance with all applicable laws, rules regulations and policies, there is no assurance that new or amended laws, rules or regulations will not be enacted, new policy applied or that existing laws, rules, regulations or discretion will not be applied in a manner which could have a material adverse effect on our business, results of operations, financial condition and the Eldorado Gold share price, including changes to the fiscal regime, in any of the countries in which we operate, including, without limitation:

•laws regarding government ownership of or participation in projects;

•laws regarding permitted foreign investments;

•royalties, taxes, fees and imposts;

•regulation of, or restrictions on, importation of goods and movement of personnel;

•regulation of, or restrictions on, currency transactions;

•regulation of, or restrictions on, sales of our products,or other laws generally applicable in such country, or changes to the ways in which any of these laws are applied, any of which could have a material adverse effect on our business, results of operations, financial condition and the Eldorado Gold share price; and

•laws regarding social and environmental regulation, including environmental reporting requirements.

We are subject to corporate governance guidelines and disclosure standards that apply to Canadian companies listed on the TSX, and with corporate governance standards that apply to us as a foreign private issuer listed on the NYSE and registered with the SEC in the United States.

Although we substantially comply with NYSE's corporate governance guidelines, we are exempt from certain NYSE requirements because we are subject to Canadian corporate governance requirements. We may from time to time seek other relief from corporate governance and exchange requirements and securities laws from the NYSE and other regulators.

Sarbanes-Oxley Act (SOX)

We document and test our internal control procedures over financial reporting to satisfy the requirements of Section 404 of SOX. SOX requires management to conduct an annual assessment of our internal controls over financial reporting and our external auditors to conduct an independent assessment of the effectiveness of our controls as at the end of each fiscal year.

Our internal controls over financial reporting may not be adequate, or we may not be able to maintain such controls as required by SOX. We also may not be able to maintain effective internal controls over financial reporting on an ongoing basis, if standards are modified, supplemented or amended from time to time.

If we do not satisfy the SOX requirements on an ongoing and timely basis, investors could lose confidence in the reliability of our financial statements, and this could harm our business and have a negative effect on the trading price or market value of securities of Eldorado Gold.

If from time to time we do not implement new or improved controls, when required, or experience difficulties in implementing them, it could harm our financial results or we may not be able to meet our reporting obligations. There is no assurance that we will be able to remediate material weaknesses, if any are identified in future periods, or maintain all of the necessary controls to ensure continued compliance. There is also no assurance that we will be able to retain personnel who have the necessary finance and accounting skills because of the increased demand for qualified personnel among publicly traded companies.

If any of our staff fail to disclose material information that is otherwise required to be reported, no evaluation can provide complete assurance that our internal controls over financial reporting will detect this. The effectiveness of our controls and procedures over financial reporting may also be limited by simple errors or faulty judgments. Continually enhancing our internal controls over financial reporting is important, especially as we expand and the challenges involved in implementing appropriate internal controls over financial reporting will increase. Although we intend to devote substantial time to ongoing compliance with this, including incurring the necessary costs associated with therewith, we cannot be certain that we will be successful in complying with Section 404 of SOX.

We are subject to changing rules and regulations promulgated by a number of United States and Canadian governmental and self-regulated organizations, including the SEC, Canadian Securities Administrators, the NYSE, the TSX and the Financial Accounting Standards Board. These rules and

83

regulations continue to evolve in scope and complexity and many new requirements have been created in response to laws enacted by governments, making compliance more difficult and uncertain. An example of such regulatory development is the SEC's "Modernization of Property Disclosures for Mining Registrants" (the "New Rule").

The SEC has adopted the New Rule to replace the existing SEC Industry Guide 7. The New Rule has become effective for SEC registrants for fiscal years beginning on or after January 1, 2021. While Eldorado is currently exempt from the New Rule as it files its annual report in accordance with the multijurisdictional disclosure system between Canada and the United States ("MJDS"), if Eldorado loses its ability to file in accordance with MJDS or if Eldorado files certain registration statements with the SEC, Eldorado would be required to comply with the New Rule. While the New Rule has similarities with NI 43-101, Eldorado may be required to update or revise all of its existing technical reports, which may result in revisions (either upward or downward) to Eldorado's mineral reserves and mineral resources, in order to comply with the New Rule. In addition, the New Rule is subject to unknown interpretations, which could require Eldorado to incur substantial costs associated with compliance.

Eldorado's efforts to comply with the Canadian and United States rules and regulations and other new rules and regulations regarding public disclosure have resulted in, and are likely to continue to result in, increased general and administrative expenses and a diversion of management time and attention from revenue-generating activities to compliance activities.

If Eldorado fails to comply with such regulations, it could have a material adverse effect on our business, results of operations, financial condition and the Eldorado Gold share price.

Commodity Price Risk

The profitability of the Company's operations depend, in large part, upon gold, silver, copper, and other commodity prices. Gold, copper, and other commodity prices can fluctuate widely and can be influenced by many factors beyond its control, including but not limited to: industrial demand, political and economic events (global and regional), gold and financial market volatility and other market factors, the popularity of cryptocurrencies as an alternative investment to gold, and central bank purchases and sales of gold and gold lending.

The global supply of gold is made up of new production from mining, and existing stocks of bullion, scrap and fabricated gold held by governments, public and private financial institutions, industrial organizations and private individuals.

If metal prices decline significantly, or decline for an extended period, Eldorado might not be able to continue operations, develop properties, or fulfill obligations under its permits and licenses, or under the agreements with partners and could increase the likelihood and amount that we may be required to record as an impairment charge on our assets. This could result in losing the ability to operate some or all of the Company's properties economically, or being forced to sell them, which could have a negative effect on our business, results of operations, financial condition and the Eldorado Gold share price.

The cost of production, development and exploration varies depending on the market prices of certain mining consumables, including diesel fuel, electricity and chemical reagents. Electricity is regionally priced in Türkiye and semi-regulated by the Turkish government, which reduces the risk of price fluctuations. The Company has elected to hedge some of its exposure to commodity price risk for gold and copper with a limited forward sales contract (for delivery on June 30, 2026). The Company may in the future elect to continue or further hedge, from time to time, commodity price contracts to manage its exposure to fluctuations in the price of gold, copper, and other metals. However there is no assurance that Eldorado will be able to conduct further hedging on reasonable terms or that any hedges that have been, or may be, put in place will mitigate these risks or that they will not cause us to experience less favourable economic outcomes than we would have experienced if we had no hedges in place.

In May 2023, we entered into a series of zero-cost gold collar contracts in order to manage cash flow variability during the construction period of Skouries. At December 31, 2023 there are 400,008 ounces of gold derivative contracts outstanding, and 16,667 ounces settle monthly with a weighted average put strike price of $1,850 per ounce and a weighted average call strike price of $2,716 per ounce. The 2023 contracts matured without any financial settlement required.

Mineral Tenure

In the countries in which we operate, the mineral rights, or certain portions of them, are owned by the relevant governments. In such countries, we must enter into contracts with the applicable governments, or obtain permits or concessions from them, that allow us to hold rights over mineral rights and rights

84

(including ownership) over parcels of land and conduct our operations thereon. The availability of such rights and the scope of operations we may undertake are subject to the discretion of the applicable governments and may be subject to conditions. New laws and regulations, or amendments to laws and regulations relating to mineral tenure and land title and usage thereof, including expropriations and deprivations of contractual rights, if proposed and enacted, may affect our rights to our mineral properties.

In many instances, we can initially only obtain rights to conduct exploration activities on certain prescribed areas, but obtaining the rights to proceed with development, mining and production on such areas or to use them for other related purposes, such as waste storage or water management, is subject to further application, conditions or licenses, the granting of which are often at the discretion of the governments. In many instances, our rights are restricted to fixed periods of time with limited, and often discretionary, renewal rights. Delays in the process for applying for such rights or renewals or expansions, or the nature of conditions imposed by government, could have a material adverse effect on our business, including our existing developments and mines, and our results of operations, financial condition and the Eldorado Gold share price.

The cost of holding these rights often escalates over time or as the scope of our operating rights expands. There is no assurance that the mineral rights regimes under which we hold properties or which govern our operations thereon will not be changed, amended, or applied in a manner which could have a material adverse effect on our business, results of operations, financial condition and the Eldorado Gold share price, that the ongoing costs of obtaining or maintaining our rights will remain economic and not result in uncompensated delays or that compliance with conditions imposed from time to time will be practicable. Any inability to obtain and retain rights to use lands for our ongoing operations at all or on a timely basis could have a material adverse effect on our business, results of operations, financial condition and the Eldorado Gold share price.

It is possible that our present or future tenure may be subject to challenges, prior unregistered agreements or transfers, and competing uses. In addition, certain lands in Canada are subject to indigenous rights, treaty rights and/or asserted rights in and to traditional territories. Our rights may also be affected by undetected defects in title. There is no assurance that any of our holdings will not be challenged. We may also be subject to expropriation proceedings for a variety of reasons. When any such challenge or proceeding is in process, we may suffer material delays in our business and operations or suspensions of our operations, and we may not be compensated for resulting losses. Any defects, challenges, agreements, transfers or competing uses which prevail over our rights, and any expropriation of our holdings, could have a material adverse effect on our business, including our total loss of such rights, and our results of operations, financial condition and share price.

Certain of our mining properties are subject to royalty and other payment obligations. If we fail to meet any such obligations, we may lose our rights.

There is no assurance that we will be able to hold or operate on our properties as currently held or operated or at all, or that we will be able to enforce our rights with respect to our holdings, which could have a material adverse effect on our business, results of operations, financial condition and the Eldorado Gold share price.

Permits

Activities in the nature of our business and operations can only be conducted pursuant to a wide range of permits and licenses obtained or renewed in accordance with the relevant laws and regulations in the countries in which we operate. These include permits and licenses, which authorize us to, conduct business in such countries; import or export goods and materials; employ foreign personnel in-country; and operate equipment, among other things.

In connection with the scoping of projects, we may be actively discussing permits with various government authorities. The duration and success of each permitting process are contingent upon many factors that we do not control. In the case of foreign operations, granting of government approvals, permits and licenses is, as a practical matter, subject to the discretion of the applicable governments or government officials. There may be delays in the review process. If the Company experiences such delays, the Company may be required to pay standby costs for the period during which activities are suspended, including payment of a portion of the salaries to those employees who have been suspended pending resolution of the permitting process. In addition, certain of Eldorado's mining properties are subject to royalty and other payment obligations. Failure to meet Eldorado's payment obligations under these agreements could result in the loss of its rights.

In the context of environmental protection permitting, including the approval of reclamation plans, we are required to comply with existing laws and regulations and other standards that may entail greater or lower

85

costs and delays depending on the nature of the activity to be permitted and the interpretation of the laws and regulations implemented by the permitting authority.

We have in the past experienced significant delays in the timely receipt of necessary permits and authorizations from the Hellenic Republic in order to advance operations in Greece, including in respect of Skouries. As a result, Skouries was placed on care and maintenance and these delays had impacted the Company's business and financial condition. We currently hold all necessary permits for the development of Skouries mine, but it has to be noted it is possible that in the future other delays in the timely receipt of necessary permits may delay or otherwise impact our operations. Delays and other impacts may be further exacerbated by legal challenges, reviews, or appeals by various government and non-government organizations.

In Q2 2023, we obtained a modification and time extension (up to 2038) of the Kassandra Mines Environmental Terms approval (the “2023 Environmental Terms Approval”) which covers the expansion of the Olympias processing facility and the Stratoni port modernization. Our current Environmental Terms are valid through to April 2038 and cover all of our operations.In June 2023, local associations and residents around the Kassandra Mines filed an appeal for the annulment of the 2023 Environmental Terms Approval. The appeal claims legal grounds relating to the Investment Agreement, and requests that the provisions concerning the independent environmental auditor and certain environmental provisions should be annulled. The Company has filed an intervention, and the hearing is expected to occur within 2024.In the case of a partial or full annulment the 2023 Environmental Terms Approval, the 2011 Environmental Terms (as applicable in 2023) would still be valid on the relevant chapters.However, any provisions in the 2023 Environmental Terms not covered by the 2011 Environmental Terms would be subject to a new approval process and, depending on the extent of the relevant provisions and process duration, could have a material adverse effect on our business, results of operations, financial condition and the Eldorado Gold share price.

In addition, some of our current mineral tenures, licenses and permits, including environmental and operating permits for Olympias, are due to expire prior to our planned life of mines, and will require renewals on terms acceptable to Eldorado. There are relevant provisions for their renewal in the Investment Agreement, however there is no assurance that we will be able to obtain or renew these tenures and permits in order to conduct our business and operations, in a timely manner or at all, or that we will be in a position to comply with all conditions that are imposed. The failure to obtain or renew such tenure and permits, or the imposition of extensive conditions, could have a material adverse effect on our business, results of operations, financial condition and the Eldorado Gold share price.

Environmental, Sustainability and Governance Practices and Performance

There is increased scrutiny from affected and interested parties related to our ESG practices, performance and disclosures, including prioritization of sustainable and responsible production practices, decarbonization and management of climate risk, tailings stewardship and social license to operate among others in the jurisdictions where we operate. As highlighted in our annual sustainability report, we have adopted an approach to responsible mining, articulated in our sustainability framework and delivered upon through the implementation of our sustainability management system.

It is possible that our affected parties might not be satisfied with our ESG practices, performance and/or disclosures, or the speed of their adoption, implementation and measurable success. If we do not meet these evolving expectations, our reputation, our access to and cost of capital, and our stock price could be negatively impacted.

In addition, our customers and end users may require that we implement certain additional ESG procedures or standards before they will start or continue to do business with us, which could lead to preferential buying based on our ESG practices compared to our competitors' ESG practices.

Investor advocacy groups, certain institutional investors, investment funds, creditors and other influential investors are increasingly focused on our ESG practices and in recent years have placed increasing importance on the implications of their investments. Organizations that provide information to investors on ESG performance and related matters have developed quantitative and qualitative data collection processes and ratings processes for evaluating companies on their approach to ESG matters. Such ratings are used by some investors to inform their investment and voting decisions. Unfavorable ratings or assessment of our ESG practices may lead to negative investor sentiment toward us, which could have a negative impact on our stock price and our access to and cost of capital. Additionally, if we do not adapt to or comply with investor or affected party expectations and standards, which are evolving, or if we are perceived to have not responded appropriately, regardless of whether there is a legal requirement to do so, we may suffer from reputational damage and our business, financial condition, and/or stock price could be materially and adversely affected.

86

Eldorado takes seriously our obligation to respect and promote human rights, is a signatory to the United Nations Global Compact, and has adopted a Human Rights Policy informed by the International Bill of Human Rights, the Ten Principles of the UN Global Compact, the International Labour Organization's Declaration on Fundamental Principles and Rights at Work, the Voluntary Principles on Security and Human Rights and the Guiding Principles on Business and Human Rights. Effective January 1, 2024, Eldorado Gold and Eldorado Quebec are subject to Canada’s new Modern Slavery Act. Later this year, Eldorado will be preparing and delivering the necessary disclosure document listing, among other things, steps that Eldorado has taken to prevent and reduce risks of forced labour and child labour.

Although the Company has implemented a number of significant measures and safeguards, including our Human Rights Policy, which are intended to ensure that personnel understand and uphold human rights standards, the implementation of these measures will not guarantee that personnel, national police or other public security forces will uphold human rights standards in every instance.

The failure to conduct operations in accordance with Company standards, including those described in our annual sustainability report and Human Rights Policy, can result in harm to employees, community members or trespassers, increase community tensions, reputational harm to us or result in criminal and/or civil liability and/or financial damages or penalties.

Financial Reporting

Carrying Value of Assets

The carrying value of our assets is compared to our estimates of their estimated fair value to assess how much value can be recovered based on current events and circumstances. Our fair value estimates are based on numerous assumptions and are adjusted from time to time and the actual fair value, which also varies over time, could be significantly different than these estimates.

If our valuation assumptions prove to be incorrect, or we experience a decline in the fair value of our reporting units, then this could result in an impairment charge, which could have an adverse effect on our business and the value of our securities.

Change in Reporting Standards

Changes in accounting or financial reporting standards may have an adverse impact on our financial condition and results of operations in the future.

Non-Governmental Organizations

Certain non-governmental organizations ("NGOs") that oppose globalization and resource development are often vocal critics of the mining industry and its practices, including the use of hazardous substances in processing activities and the related environmental impact, and such NGOs may oppose our current and future operations or further development or new development of projects or operations on such grounds. Adverse publicity generated by such NGOs or other parties generally related to extractive industries or specifically to our operations, could have an adverse effect on our reputation, impact our relationships with the communities in which we operate and ultimately have a material adverse effect on our business, results of operations, financial condition and the Eldorado Gold share price.

NGOs may lobby governments for changes to laws, regulations and policies pertaining to mining and relevant to our business activities which, if made, could have a material adverse effect on our business, results of operations, financial condition and the Eldorado Gold share price.

NGOs may organize protests, install road blockades, apply for injunctions for work stoppage, file lawsuits for damages and intervene and participate in lawsuits seeking to cancel our rights, permits and licenses. These actions can relate not only to current activities but also historic mining activities by prior owners and could have a material adverse effect on our business and operations. NGOs may also file complaints with regulators in respect of our, and our directors' and insiders' regulatory filings in respect of Eldorado Gold. Such complaints, regardless of whether they have any substance or basis in fact or law, may have the effect of undermining the confidence of the public or a regulator in Eldorado Gold or such directors or insiders. This may adversely affect our prospects of obtaining the regulatory approvals necessary for advancement of some or all of our exploration and development plans or operations and our business, results of operations, financial condition and the Eldorado Gold share price.

Corruption, Bribery and Sanctions

Our operations are governed by, and involve interactions with, many levels of government in numerous countries. Like most companies, we are required to comply with anti-corruption and anti-bribery laws,

87

including the Criminal Code (Canada) and the Corruption of Foreign Public Officials Act (Canada) and the U.S. Foreign Corrupt Practices Act, as well as similar laws that apply to our business including in the countries in which we conduct our business or our securities trade (collectively, "anti-bribery laws"). The Company has implemented and promulgated an Anti-Bribery & Corruption Policy, which with our Code of Ethics and Business Conduct, all directors, officers and employees are required to comply.

In recent years, there has been a general increase in both the severity of penalties and frequency of prosecution and enforcement under such laws, resulting in greater punishment and scrutiny to companies convicted of violating anti-bribery laws. Furthermore, a company may be found liable for violations by not only its directors, officers or employees, but also through the actions of any third party agents or representatives. Although we have adopted policies and use a risk-based approach to mitigate such risks, such measures may not always be effective in ensuring that we, our directors, officers, employees or third party agents or representatives will strictly be in compliance with such anti-bribery laws. If we find ourselves subject to an enforcement action or are found to be in violation of such anti-bribery laws, this may result in significant criminal penalties, fines and/or sanctions being imposed on us and significant negative media coverage resulting in a material adverse effect on our reputation, business, results of operations, financial condition and the Eldorado Gold share price.

The operation of our business may also be impacted by anti-terrorism, economic or financial sanction laws including the Criminal Code (Canada), the United Nations Act (Canada), the Special Economic Measures Act (Canada), the Justice for Victims of Corrupt Foreign Officials Act (Sergei Magnitsky Law) (Canada) and the Freezing Assets of Corrupt Foreign Officials Act (Canada), and more recently, the concerted sanctions against Russia in response to the Russia-Ukraine war, as well as similar laws in countries in which we conduct our business or our securities trade (collectively, "sanctions laws"). Throughout 2022 we experienced substantial price increases for certain commodities and consumables as a result of supply concerns caused by financial and trade sanctions against Russia, and ongoing supply chain challenges due to COVID-19. Cost increases primarily impacted electricity at operations in Greece and Türkiye, and fuel and reagents at Kışladağ. Input prices have not yet returned to pre-COVID-19 levels. Such sanctions laws and any regulations, orders or policies issued thereunder may impose restrictions and prohibitions on trade, financial transactions, investments and other economic activities with sanctioned or designated foreign individuals or companies from a target country, industries, markets, countries or regions within countries. These restrictions and prohibitions may also apply to dealings with non-state actors such as terrorist organizations and may change from time to time. These restrictions and prohibitions may also apply to affiliates of sanctioned or designated persons and those acting on their behalf as agents or representatives. Sanctions laws are continually being updated in order to respond to unexpected events and occurrences across the globe. We use our best efforts to react as soon as possible to changes in sanctions laws across the globe. However, it takes time for us to review the updates. These potential delays are sometimes exacerbated by the reality that governments do not necessarily provide sufficient guidance for businesses wanting to comply with applicable laws. Although we do not believe that we are in contravention of such sanctions laws, there is no assurance that we are or will be in full compliance at all times and that there will not be a material adverse effect on our reputation, business, results of operations, financial condition and the Eldorado Gold share price.

Information and Operational Technology Systems

Our operations depend, in part, upon information and operational technology systems. Our information and operational technology systems, including machines and equipment, are subject to disruption, damage, disabling, misuse, malfunction or failure from a number of sources, including, but not limited to, hacking, computer viruses, security breaches, natural disasters, power loss, vandalism, theft, malware, cyber threats, extortion, employee error, malfeasance and defects in design. We may also be a target of cyber surveillance or a cyber-attack from cyber criminals, industrial competitors or government actors. Any of these and other events could result in information and operating technology systems failures, operational delays, production downtimes, operating accidents, loss of revenues due to a disruption of activities, incurring of remediation costs, including ransom payments, destruction or corruption of data, release of confidential information in contravention of applicable laws, litigation, fines and liability for failure to comply with privacy and information security laws, access to proprietary or sensitive information, security breaches or other manipulation or improper use of our data, systems and networks, regulatory investigations and heightened regulatory scrutiny, any of which could have material adverse effects on our reputation, business, results of operations, financial condition and the Eldorado Gold share price.

Although to date we have not experienced any material losses relating to cyber-attacks or other information security breaches, there is no assurance that we will not incur such losses in the future. Our risk and exposure to these matters cannot be fully mitigated because of, among other things, the evolving nature of these threats. As a result, cyber security and the continued development and enhancement of controls, processes and practices designed to protect our systems, computers, software, data and networks from attack, damage or unauthorized access remain a priority. As cyber threats continue to evolve, we may be required to expend additional resources to continue to modify or enhance protective

88

measures or to investigate and remediate any security vulnerabilities. Risks related to cyber security are monitored on an ongoing basis by Eldorado Gold's senior management and Board of Directors.

We could also be adversely affected by system or network disruptions if new or upgraded information or operational technology systems are defective, not installed properly or not properly integrated into our operations. Various measures have been implemented to manage our risks related to system implementation and modification, but system modification failures could have a material adverse effect on our business, financial position, results of operations and the Eldorado Gold share price and could, if not successfully implemented, adversely impact the effectiveness of our internal controls over financial reporting.

Any damage, disabling, misuse, malfunction or failure that causes an interruption in operations could have an adverse effect on the production from and development of our properties. While we have systems, policies, hardware, practices and procedures designed to prevent or limit the effect of disabling, misuse, malfunction or failure of our operating facilities, infrastructure, machines and equipment, there can be no assurance that these measures will be sufficient and that any such failures or interruptions will not occur or, if they do occur, that they will be adequately addressed in a timely manner.

Litigation and Contracts

We are periodically subject to legal claims that are with and without merit. We are regularly involved in routine litigation matters. We believe that it is unlikely that the final outcome of these routine proceedings will have a material adverse effect on us; however, defense and settlement costs can be substantial, even for claims that are without merit.

Due to the inherent uncertainty of the litigation process, including arbitration proceedings, and dealings with regulatory bodies, there is no assurance that any legal or regulatory proceeding will be resolved in a manner that will not have a material and/or adverse effect on us. In the event of a dispute arising from foreign operations, the Company may be subject to the exclusive jurisdiction of foreign courts or arbitration panels or may not be successful in subjecting foreign persons to the jurisdiction of courts in Canada.

In our business, we make contracts with a wide range of counterparties. There can be no assurance that these contracts will be honoured and performed in accordance with their terms by our counterparties or that we will be able to enforce the contractual obligations.

We do not believe, based on currently available information, that the outcome of any individual legal proceeding will have a material adverse effect on our financial condition, although individual or cumulative outcomes could be material to our operating results for a particular period, depending on the nature and magnitude of the outcome and the operating results for the period.

Estimation of Mineral Reserves and Mineral Resources

Estimates Only

Mineral Reserve and Mineral Resource estimates are only estimates and we may not produce gold or other metals in the quantities estimated.

Proven and Probable Mineral Reserve estimates may need to be revised based on various factors including:

•actual production experience;

•our ability to continue to own and operate our mines and property;

•fluctuations in the market price of gold, copper, or other metals;

•results of drilling or metallurgical testing;

•production costs; and

•recovery rates.

The cut-off values and cut-off grades for the Mineral Reserves and Mineral Resources are based on our assumptions about plant recovery, metal prices, mining dilution and recovery, and our estimates for operating and capital costs, which are based on historical production figures. We may have to recalculate our estimated Mineral Reserve and Resources based on actual production or the results of exploration. Fluctuations in the market price of gold, unanticipated increases in production costs (such as labour, energy, or other key inputs) or recovery rates can make it unprofitable for us to develop or operate a particular property for a period of time. As part of the annual Mineral Reserves and Mineral Resources review process, a summary of which was published on December 13, 2023 with an effective date of September 30, 2023, cut-off values or cut-off grades were updated to reflect current operating and market

89

conditions. If there is a material decrease in our mineral reserve estimates, or our ability to extract the mineral reserves, it could have a material adverse effect on our future cash flow, business, results of operations, financial condition and the Eldorado Gold share price.

There are uncertainties inherent in estimating Proven and Probable Mineral Reserves and Measured, Indicated and Inferred Mineral Resources, including many factors beyond our control. Estimating Mineral Reserves and Resources is a subjective process. Accuracy depends on the quantity and quality of available data and assumptions and judgments used in engineering and geological interpretation, which may be unreliable or subject to change. It is inherently impossible to have full knowledge of particular geological structures, faults, voids, intrusions, natural variations in and within rock types and other occurrences. Additional knowledge gained or failure to identify and account for such occurrences in our assessment of mineral reserves and resources may make mining more expensive and cost prohibitive, which will have a material adverse effect on our future cash flow, business, results of operations, financial condition and the Eldorado Gold share price.

There is no assurance that the estimates are accurate, that Mineral Reserve and Resource figures are accurate, or that the Mineral Reserves or Resources can be mined or processed profitably. Mineral Resources that are not classified as Mineral Reserves do not have demonstrated economic viability. You should not assume that all or any part of the Measured Mineral Resources, Indicated Mineral Resources, or an Inferred Mineral Resource will ever be upgraded to a higher category or that any or all of an Inferred Mineral Resource exists or is economically or legally feasible to mine.

Because mines have limited lives based on Proven and Probable Mineral Reserves, we must continually replace and expand our Mineral Reserves and any necessary associated surface rights as our mines produce gold and their LOM is reduced.

Our ability to maintain or increase annual production of gold and other metals will depend significantly on:

•the geological and technical expertise of our management and exploration teams;

•the quality of land available for exploration;

•our mining and processing operations;

•our ability to conduct successful exploration efforts; and

•our ability to develop new projects and make acquisitions.

As we explore and develop a property, we are constantly determining the level of drilling and analytical work required to maintain or upgrade our confidence in the geological model. Depending on continuity, the amount of drilling will vary from deposit to deposit. The degree of analytical work is determined by the variability in the ore, the type of metallurgical process used and the potential for deleterious elements in the ore. We do not drill exhaustively at all deposits or analyze every sample for every known element as the cost would be prohibitive. Therefore, unknown geological formations are possible, which could limit our ability to access the ore or cut off the ore where we are expecting continuity. It is also possible that we have not correctly identified all metals and deleterious elements in the ore in order to design metallurgical processes correctly.

There may be associated metals or minerals that are deleterious to the extraction process or that may make downstream metallurgical processes more difficult. The presence of these metals or minerals may result in us having problems in developing a process that will allow us to extract the ore economically. Alternatively, the ore may not be as valuable as we anticipate due to the lower recoveries received or the penalties associated with extraction of deleterious materials that are sold as part of the saleable product.

There is no assurance that our exploration programs will expand our current mineral reserves or replace them with new mineral reserves. Failure to replace or expand our mineral reserves, as well as maintain or increase our annual production of gold and other metals, could have an adverse effect on our business, results of operations, financial condition and the Eldorado Gold share price.

Different Standards

The standards used to prepare and report mineral reserves and mineral resources in this AIF differ from the requirements of the SEC that are applicable to domestic United States reporting companies. Any mineral reserves and mineral resources reported by Eldorado in accordance with NI 43-101 may not qualify as such under SEC standards, including the New Rule. Accordingly, information contained in this AIF containing descriptions of the Eldorado mineral deposits may not be comparable to similar information made public by United States companies subject to the reporting and disclosure requirements under the United States federal securities laws and the rules and regulations of the SEC thereunder. See also “Reporting Mineral Reserves and Mineral Resources”.

90

Credit Risk

We may be exposed to credit risks if the counterparty to any financial instrument to which Eldorado is a party will not meet its obligations and will cause us to incur a financial loss. The Company limits counterparty risk by entering into business arrangements with high credit-quality counterparties, limiting the amount of exposure to each counterparty and monitoring the financial condition of counterparties. In accordance with the Company's short-term investment policy, term deposits and short term investments are held with high credit quality financial institutions as determined by rating agencies. For cash and cash equivalents, restricted cash, term deposits, derivative assets and accounts receivable, credit risk is represented by the carrying amount on the balance sheet.

Payment for metal sales is normally within normal business practice for receipt of goods and is dependent on the contract terms with the buyer. While the historical level of customer defaults is negligible, which has reduced the credit risk associated with trade receivables at December 31, 2023, there is no guarantee that buyers, including under exclusive sales arrangements, will not default on their commitments, which may have an adverse impact on the Company's financial performance. If there are defaults, Eldorado would be required to find alternate buyers. However, there may be delays associated with establishing new sales contracts or timing on revenue recognition of final sales.

The Company invests its cash and cash equivalents in major financial institutions and in government issuances, according to the Company's short-term investment policy. As at December 31, 2023, the Company holds a significant amount of cash and cash equivalents with various financial institutions in North America and the Netherlands. The Company monitors the credit ratings of all financial institutions in which it holds cash and investments. In recent years Türkiye’s sovereign credit ratings were downgraded, reflecting risks associated with high inflation and a depreciating currency. This was followed by the downgrade of the credit ratings of numerous Turkish banking institutions, including two at which the Company holds cash. As at December 31, 2023, deposits equivalent to approximately $9 M U.S. dollars are held in a banking institution operating in Türkiye with lower credit ratings as compared to other financial institutions at which the Company holds cash and investments. This, combined with past downgrades in Türkiye’s sovereign credit rating, expose the Company to greater credit risk. This credit risk is mitigated by a limited in-country cash balance policy; however, amounts of cash held in financial institutions in Türkiye may increase in the future in line with operational or other requirements.The credit risk associated with financial institutions in other jurisdictions continues to be considered low.There can be no assurance that certain financial institutions in foreign countries in which the Company operates will not default on their commitments.

Share Price Volatility, Volume Fluctuations and Dilution

The capital markets have experienced a high degree of volatility in the trading price and volume of shares sold over the past few years. Many companies have experienced wide fluctuations in the market price of their securities that have not necessarily related to their operating performance, underlying asset values or prospects. There is no assurance that the price of our securities will not be affected.

Future acquisitions could be made through the issuance of equity securities of Eldorado Gold. Additional funds may be needed for our exploration and development programs and potential acquisitions, which could be raised through equity issues. Issuing more equity securities can substantially dilute the interests of Eldorado Gold shareholders. Issuing substantial amounts of Eldorado Gold securities, or making them available for sale, could have an adverse effect on the prevailing market prices for Eldorado Gold's securities. A decline of the Eldorado Gold share price could hamper the ability of Eldorado Gold to raise additional capital through the sale of its securities.

Actions of Activist Shareholders

In the past, shareholders have instituted class action lawsuits against companies that have experienced volatility in their share price. Class action lawsuits can result in substantial costs and divert management's attention and resources, which could significantly harm our profitability and reputation. There is no assurance that Eldorado Gold will not be subject to class action lawsuits.

Publicly-traded companies have also increasingly become subject to campaigns by investors seeking to advocate certain governance changes or corporate actions such as financial restructuring, special dividends, share repurchases or even sales of assets or the entire company. We could be subject to such shareholder activity or demands. Given the challenges we have encountered in our businesses in past years, recent changes to our governance and strategic focus may not satisfy such shareholders who may attempt to promote or effect further changes or acquire control over us. Responding to proxy contests, media campaigns and other actions by activist shareholders, if required, will be costly and time-consuming, will disrupt our operations and would divert the attention of the Board and senior

91

management from the pursuit of our business strategies, which could adversely affect our results of operations, financial condition and/or prospects. If individuals are elected to the Board with a specific agenda to increase short-term shareholder value, it may adversely affect or undermine our ability to effectively implement our plans. Perceived uncertainties as to our future direction resulting from shareholder activism could also result in the loss of potential business opportunities and may make it more difficult to attract and retain qualified personnel and business partners, to our detriment.

Reliance on Infrastructure, Commodities and Consumables

Infrastructure

Our business and operations depend on our ability to access and maintain adequate and reliable infrastructure, including roads and bridges, power sources and water systems. We may have to build the required infrastructure if it is not readily available to us for a given project, and there is no assurance that we will be able to do so in a timely manner or at all. Inadequate, inconsistent, or costly infrastructure could compromise many aspects of a project's feasibility, viability and profitability, including, but not limited to, construction schedules, capital and operating costs, and labour availability, among others.

There is no assurance that we can access and maintain the infrastructure we need and many critical sites have only single road access (that could be closed for reasons beyond our control such as accidents or adverse weather). There is also no assurance that, where necessary, we will be able to obtain rights of way, raw materials and government authorizations and permits to construct, or upgrade the same, at a reasonable cost, in a timely manner, or at all.

Our access to infrastructure and the commodities discussed below may be interrupted by natural causes, such as drought, floods, wildfires, earthquakes and other weather phenomena, or man-made causes, such as blockades, sabotage, conflicts, government issues, political events, protests, rationing or competing uses. For example, the Stratoni mine experienced a fall of ground on June 27, 2021. There were no injuries, however, an investigation revealed several other locations with similar ground support conditions. In line with strict safety protocols, operations at Stratoni were suspended during July and August of 2021 to remediate ground support conditions. Mining resumed at Stratoni in September 2021 but was suspended again at the end of 2021 as the mine transitions to care and maintenance. While we will evaluate resuming operations subject to exploration success and positive results of further technical and economic review, there is no assurance that such incidents may not occur again at the Stratoni mine or at other of Eldorado's mines. Starting in late May 2023, wildfires in the Abitibi region impacted operations at Lamaque and a number of shifts were suspended.We re-sequenced the maintenance schedule and devised an alternative route to safely get employees to the Triangle underground. At Kisladag, the risks are expected to be related to severe precipitation events or precipitation induced landslides, and their impact on water levels and site infrastructure. In 2023, heavy rains resulted in unanticipated impacts on heap leaching operations at Kisladag. The increased precipitation selectively mobilized fine particles which created variability in permeability and in turn lead to an increase in metal inventory in the leach facility. The increased precipitation percolated through the heap and was captured in the solution ponds as anticipated. Our inability to obtain or build and to maintain adequate and continuous access to infrastructure and substantial amounts of commodities, power and water, at a reasonable cost, could have a material adverse effect on our business, results of operations, financial condition and the Eldorado Gold share price. See also “Climate Change”.

Power and Water

Our mining operations use substantial volumes of water and power during extraction and processing. Our ability to obtain secure supplies of power and water at a reasonable cost depends on a number of factors that may be out of our control, including global and regional supply and demand, political and economic conditions and problems affecting local supplies, among others.

There is no assurance that we will be able to secure the required supplies of power and water on reasonable terms or at all and, if we are unable to do so or there is an interruption in the supplies we do obtain or a material increase in prices, then it could have a material adverse effect on our business, results of operations, financial condition and the Eldorado Gold share price.

Commodities and Consumables

Our business operations use a significant amount of commodities, consumables and other materials. Prices for diesel fuel, steel, concrete, chemicals (including explosives, lime and cyanide) and other materials, commodities and consumables required for our operations can be volatile and price changes can be substantial, occur over short periods of time and are affected by factors beyond our control. Prices for electricity, fuel, and other materials, commodities and consumables required for our operations

92

experienced substantial increases during 2022 amid supply concerns caused by, among other things, financial and trade sanctions against Russia. These cost increases may be prolonged and have a material adverse effect on our business, financial condition and results of operations. Higher costs for, or tighter supplies of, construction materials like steel and concrete can affect the timing and cost of our development projects, including Skouries.

If there is a significant and sustained increase in the cost of certain commodities, we may decide that it is not economically feasible to continue some or all of our commercial production and development activities, and this could have an adverse effect on our business, results of operations, financial condition and the Eldorado Gold share price.

We may maintain significant inventories of operating consumables, based on the frequency and reliability of the delivery process for such consumables and anticipated variations in regular use. We depend on suppliers to meet our needs for these commodities; however, sometimes no source for such commodities may be available. If the rates of consumption for such commodities vary from expected rates significantly or delivery is delayed for any reason, we may need to find a new source or negotiate with existing sources to increase supply. If any shortages are not rectified in a timely manner, it may result in reduced recovery or delays in restoring optimal operating conditions.

Higher worldwide demand for critical resources, such as drilling equipment and tires, could affect our ability to acquire such resources and lead to delays in delivery and unanticipated cost increases, which could have an effect on our operating costs, capital expenditures and production schedules.

Further, we rely on certain key third-party suppliers and contractors for equipment, raw materials and services used in, and the provision of services necessary for, the development, construction and continuing operation of our assets. As a result, our operations are subject to a number of risks, some of which are outside of our control, including negotiating agreements with suppliers and contractors on acceptable terms, and the inability to replace a supplier or contractor and its equipment, raw materials or services if either party terminates the agreement, among others.

The occurrence of one or more of these risks could have a material adverse effect on our business, results of operations, financial condition and the Eldorado Gold share price.

Currency Risk

We sell gold in U.S. dollars, but incur costs in several currencies, including U.S. dollars, Canadian dollars, Turkish Lira, Euros and Romanian Lei. Any change in the value of any of these currencies against the U.S. dollar can change production costs and capital expenditures, which can affect future cash flows, business, results of operations, financial condition and the Eldorado Gold share price and lead to higher operation, construction, development and other costs than anticipated. As of December 31, 2023, approximately 80% of Eldorado's cash, cash equivalents and term deposits was held in U.S. dollars.

We have a risk management policy that contemplates potential hedging of our foreign exchange exposure to reduce the risk associated with currency fluctuations. During 2023, we entered into zero-cost collars to reduce the risk associated with fluctuations of the Euro and Canadian dollar at the Olympias mine and Lamaque operations, respectively. In August and October 2023, the Company entered into foreign exchange forward contracts to fix the U.S. Dollar to Euro exchange rate for a portion of the Company's equity commitment for the Skouries Project. In December 2022, we announced that Hellas Gold had entered into an interest rate swap, covering 70% of its variable interest rate exposure, in accordance with the terms of our Term Facility. Hellas also entered into foreign exchange hedging arrangements to fix U.S. dollars to Euros for a portion of the Term Facility repayments.

These derivatives set a band within which we expect to be able to protect against currency movements, either above or below specific strike prices. There is no assurance that Eldorado will be able to obtain hedging on reasonable terms in the future or that any hedges that may be put in place will mitigate these risks or that they will not cause us to experience less favourable economic outcomes than we would have experienced if no hedges were in place. For example, the Turkish Lira lost approximately 57% of its value against the U.S. dollar in 2023 and volatility remains a possibility in the future. While the ultimate impact of recent currency fluctuations impacting the Turkish Lira is difficult to predict and depends on factors that are evolving beyond our control, these and other impacts of foreign exchange exposure could also have the effect of heightening certain of the other risks described under "Foreign Operations", “Credit Risk” and "Government Regulation".

The table below show our assets and liabilities denominated in currencies other than the U.S. dollar at December 31, 2023. We recognized a gain of $16.0 M on foreign exchange from continuing operations in 2023, compared to a gain of $9.7 M from continuing operations in 2022.

Interest Rate Risk

Interest rates determine how much interest the Company pays on its debt, and how much is earned on cash and cash equivalent balances, which can affect future cash flows.

The Notes have a fixed interest rate of 6.25%. Borrowings under the Fourth ARCA are at variable rates of interest based on SOFR and the spread adjustment based on the tenor. Draws on the Fourth ARCA are at variable rates of interest which expose the Company to interest rate risk. At December 31, 2023, no amounts were drawn under the Fourth ARCA.

The Company may enter into interest rate swaps in the future, involving the exchange of floating for fixed rate interest payments, in order to reduce interest rate volatility. However, there is no assurance that Eldorado will be able to obtain interest rate swaps on reasonable terms or that any interest rate swaps that may be put in place will mitigate these risks or that they will not cause us to experience less favourable economic outcomes than we would have experienced if we had no such swaps in place.

After years of historically low interest rates, in 2022 and the first half of 2023, central banks around the world raised interest rates in an effort to combat inflation. To the extent inflation remains elevated, central banks around the world may choose to hold or further increase interest rates from where they currently are. Where interest rates remain elevated, this may impact the Company’s ability to take on additional indebtedness at favourable rates, or refinance existing indebtedness at rates similar to those previously offered to the Company. For example, the Company’s Fourth ARCA will need to be refinanced before maturity in 2025. Failure to secure additional indebtedness at favourable rates, or refinancing existing indebtedness like the Fourth ARCA at similar rates to what existing prior to maturity, could result in a material adverse effect on our business, results of operations, financial condition and the Eldorado Gold share price.

Tax Matters

We operate and have operated in a number of countries, each of which has its own tax regime to which we are subject. The tax regime and the enforcement policies of tax administrators in each of these countries are complicated and may change from time to time, all of which are beyond our control. Our investments into these countries, importation of goods and material, land use, expenditures, sales of gold and other products, income, repatriation of money and all other aspects of our investments and operations can be taxed, and there is no certainty as to which areas of our operations will be assessed or taxed from time to time or at what rates.

Our tax residency and the tax residency of our subsidiaries (both current and past) are affected by a number of factors, some of which are outside of our control, including the application and interpretation of the relevant tax laws and treaties. If we or our subsidiaries are ever assessed to be a non-resident in the jurisdictions that we or our subsidiaries report or have reported or are otherwise assessed, or are deemed

94

to be resident (for the purposes of tax) in another jurisdiction, we may be liable to pay additional taxes. In addition, we have entered into various arrangements regarding the sale of mineral products or mineral assets, which may be subject to unexpected tax treatment. If such taxes were to become payable, this could have a material adverse effect on our business, results of operations, financial condition and the Eldorado Gold share price.

We endeavor to structure, and restructure from time to time, our corporate organization in a commercially efficient manner and if any such planning effort is considered by a taxation authority to constitute tax avoidance, then this could result in increased taxes and tax penalties, which could have a material adverse effect on our financial condition.

New laws and regulations or new interpretations of or amendments to laws, regulations or enforcement policy relating to tax laws or tax agreements with governmental authorities, if proposed and enacted, may affect our current financial condition and could result in higher taxes being payable by us.

There is also the potential for a change in the tariff arrangements in the countries in which Eldorado operates, as is the case for the Chinese importation specification for concentrate imports set out in the Industry Standard. There is no assurance that our current financial condition will not change in the future due to such changes. See also “Environmental”.

Dividends

While we have in place a policy for the payment of dividends on common shares of Eldorado Gold, there is no certainty as to the amount of any dividend or that any dividend may be declared in the future.

Our potential future investments will require significant funds for capital expenditures and our operating cash flow may not be sufficient to meet all of such expenditures. As a result, new sources of capital may be needed to meet the funding requirements of such investments, fund our ongoing business activities, fund construction and operation of potential future projects and various exploration projects, fund share repurchase transactions and pay dividends. If we are unable to obtain financing or service existing or future debt we could be required to reduce, suspend or eliminate or dividend payments or any future share repurchase transactions.

Reclamation and Long-Term Obligations

We are required by various governments in jurisdictions in which we operate to provide financial assurance sufficient to allow a third party to implement approved closure and reclamation plans if we are unable to do so. The relevant laws governing the determination of the scope and cost of the closure and reclamation obligations and the amount and forms of financial assurance required are complex and vary from jurisdiction to jurisdiction.

As of December 31, 2023, Eldorado has provided the appropriate regulatory authorities with non-financial and financial letters of credit of EUR 58.2 M and C$0.4 M, respectively. The letters of credit were issued to secure certain obligations in connection with mine closure obligations in the various jurisdictions in which we operate. The amount and nature of such financial assurance are dependent upon a number of factors, including our financial condition and reclamation cost estimates. Changes to these amounts, as well as the nature of the collateral to be provided, could significantly increase our costs, making the maintenance and development of existing and new mines less economically feasible. Regulatory authorities may require further financial assurance and, to the extent that the value of the collateral provided is or becomes insufficient to cover the amount that we are required to post, we could be required to replace or supplement the existing security with more expensive forms of security. This could include cash deposits, which would reduce cash available for our operations and development activities. There is no guarantee that, in the future, we will be able to maintain or add to current levels of financial assurance as we may not have sufficient capital resources to do so.

In addition, climate change could lead to changes in the physical risks posed to our operations, which could result in changes in our closure and reclamation plans to address such risks. Any modifications to our closure and reclamation plans that may be required to address physical climate risks may materially increase the costs associated with implementing closure and reclamation at any or all of our active or inactive mine sites and the financial assurance obligations related to the same. For more information on the physical risks of climate change, see the risk factor entitled "Climate Change".

Although we have currently made provision for certain of our reclamation obligations, there is no assurance that these provisions will be adequate in the future. Failure to provide the required financial assurance for reclamation could potentially result in the closure of one or more of our operations, which

95

could result in a material adverse effect on our business, results of operations, financial condition and the Eldorado Gold share price.

Acquisitions and Dispositions

Acquisitions

Although we actively seek acquisition opportunities that are consistent with our acquisition and growth strategy, we are not certain that we will be able to identify suitable candidates that are available at a reasonable price, complete any acquisition, or integrate any acquired business into our operations successfully. Acquisitions can involve a number of special risks, circumstances or legal liabilities, which could have a material adverse effect on our business, results of operations, financial condition and the Eldorado Gold share price.

Acquisitions may be made by using available cash, incurring debt, issuing common shares or other securities, or any combination of the foregoing. This could limit our flexibility to raise capital, to operate, explore and develop our properties and make other acquisitions, and it could further dilute and decrease the trading price of our common shares. When we evaluate a potential acquisition, we cannot be certain that we will have correctly identified and managed the risks and costs inherent in that business.

We have discussions and engage in other activities with possible acquisition targets from time to time, and each of these activities could be in a different stage of development. There is no assurance that any potential transaction will be completed and the target integrated with our operations, systems, management and culture successfully in an efficient, effective and timely manner or that the expected bases or sources of synergies will in fact produce the benefits anticipated. In addition, synergies assume certain long term realized gold and other metals prices. If actual prices are below such assumed prices, this could adversely affect the synergies to be realized. If we do not successfully manage our acquisition and growth strategy, it could have a material adverse effect on our business, results of operations, financial condition and the Eldorado Gold share price.

We continue to pursue opportunities to acquire advanced exploration assets that are consistent with our strategy. At any given time, discussions and activities with respect to such possible opportunities may be in process on such initiatives, each at different stages of due diligence. From time to time, we may acquire securities of, or an interest in, companies; and we may enter into acquisitions or other transactions with other companies.

Transactions involving acquisitions have inherent risks, including, accurately assessing the value, strengths, weaknesses, contingent and other liabilities and potential profitability of potential acquisitions; limited opportunity for and effectiveness of due diligence; ability to achieve identified and anticipated operating and financial synergies; unanticipated costs, liabilities and write-offs including higher capital and operating costs than had been assumed at the time of acquisition, and diversion of management attention from existing business, among others.

Any of these factors or other risks could result in us not realizing the benefits anticipated from acquiring other properties or companies, and could have a material adverse effect on our ability to grow and on our business, results of operations, financial condition and the Eldorado Gold share price.

Acquisitions can pose challenges in implementing the required processes, procedures and controls in the new operations. Companies that we acquire may not have disclosure controls and procedures or internal controls over financial reporting that are as thorough or effective as those required by the securities laws that currently apply to us.

Due to the nature of certain proposed transactions, it is possible that shareholders may not have the right to evaluate the merits or risks of any future acquisition, except as required by applicable laws and stock exchange rules.

Dispositions

When we decide to sell certain assets or projects, we may encounter difficulty in finding buyers or executing alternative exit strategies on acceptable terms in a timely manner, which could delay the accomplishment of our strategic objectives. For example, delays in obtaining tax rulings and regulatory approvals or clearances, and disruptions or volatility in the capital markets may impact our ability to complete proposed dispositions. Alternatively, we may dispose of a business at a price or on terms that are less than we had anticipated. After reaching an agreement with a buyer or seller for the disposition of a business, we may be required to obtain necessary regulatory and governmental approvals on acceptable terms and pre-closing conditions may need to be satisfied, all of which may prevent us from completing the transaction. Dispositions may impact our production, mineral reserves and resources and

96

our future growth and financial conditions. Despite the disposition of divested businesses, we may continue to be held responsible for actions taken while we controlled and operated the business. Dispositions may also involve continued financial involvement in the divested business, such as through continuing equity ownership, guarantees, indemnities or other financial obligations. Under these arrangements, performance by the divested businesses or other conditions outside our control could affect our future financial results.

Regulated Substances

The transportation and use of certain substances that we use in our operations are regulated by the governments in the jurisdictions in which we operate. Two obvious examples are explosives and cyanide. Regulations may include restricting where the substance can be purchased; requiring a certain government department to approve or handle the purchase and transport of the substances; and restricting the amount of these substances that can be kept on-site at any time, among others.

Eldorado Gold is a signatory to the Cyanide Code, which commits us to mandating that our sites adhere to recognized best practice for the purchase, transportation, use and disposal of cyanide. Each signatory site is audited every three years to assess continued compliance. While we have a good understanding of the restrictions in the various jurisdictions, these laws may change, or the responsible parties within the government may change or not be available at a critical time when they are required to be involved in our process. This may result in delays in normal operation, or downtime, and may have an effect on our operating results in more extreme cases. The Lamaque operation has conducted a self-assessment and is currently working toward full Cyanide Code certification.

Equipment

Our operations are reliant on significant amounts of both large and small equipment that is critical to the development, construction and operation of our projects. Failures or unavailability of equipment could cause interruptions or delays in our development and construction or interruptions or reduced production in our operations (particularly where they exceed our anticipated/expected targets). These risks may be increased by the age of certain equipment. Equipment related risks include delays in repair or replacement of equipment due to unavailability or insufficient spare parts inventory; delays in repair or replacement of equipment due to a shortage of skilled labour at the Company, its equipment suppliers, or key service providers (particularly as a result of growing labour shortages throughout the mining industry and related sectors); repeated or unexpected equipment failures; and restrictions on transportation and installation of large equipment, including delays or inability to obtain required permits for such transportation or installation, among others.

Delays in construction or development of a project or periods of downtime or reductions in operations or efficiency that result from the above risks or remediation of an interruption or inefficiency in production capability could require us to make large expenditures to repair, replace or redesign equipment. All of these factors could have a material adverse effect on our business, results of operations, financial condition and the Eldorado Gold share price.

Co-ownership of Our Properties

Mining projects are often conducted through an unincorporated joint venture or a co-owned incorporated joint venture company. Co-ownership often requires unanimous approval of the parties or their representatives for certain fundamental decisions like an increase (or decrease) in registered capital, a merger, division, dissolution, amendment of the constitutional documents, and pledge of the assets, which means that each co-owner has a right to veto any of these decisions, which could lead to a deadlock. We are subject to a number of additional risks associated with co-ownership, including disagreement with a co-owner about how to develop, operate or finance the project; that a co-owner may at any time have economic or business interests or goals that are, or become, inconsistent with our business interests or goals; and that a co-owner may not comply with the agreements governing our relationship with them, among others.

Some of our interests are, and future interests may be, through co-owned companies established under and governed by the laws of their respective countries.

If a co-owner is a state-sector entity, then its actions and priorities may be dictated by government or other policies instead of purely commercial considerations. Decisions of a co-owner may have an adverse effect on the results of our operations in respect of the projects to which the applicable co-ownership relates.

97

Unavailability of Insurance

Where practical, Eldorado obtains insurance against certain risks in the operation of our business, but coverage has exclusions and limitations. There is no assurance that the insurance will be adequate to cover any liabilities, or that it will continue to be available, and at terms we believe are commercially acceptable.

In some instances, certain insurance may become unavailable or available only for reduced amounts of coverage. Significantly increased costs could lead Eldorado to decide to reduce or possibly eliminate, coverage. In addition, insurance is purchased from a number of third-party insurers, often in layered insurance arrangements, some of whom may discontinue providing insurance coverage for their own policy or strategic reasons. For example, insurance against risks such as loss of title to mineral property, environmental pollution, or other hazards as a result of exploration and production is generally not available to us or other companies in the mining industry on acceptable terms, particularly for several jurisdictions in which Eldorado operates. In the event any such insurance is or becomes unavailable, our overall risk exposure could be increased. Losses from these uninsured events may cause us to incur significant costs that could have a material adverse effect upon our business, results of operations, financial condition and the Eldorado Gold share price.

Conflicts of Interest

Certain of our directors also serve as directors of other companies involved in natural resource exploration and development, which may result in a conflict of interest in the allocation of their time between Eldorado and such other companies. There is also a possibility that such other companies may compete with us for the acquisition of assets. Consequently, there exists the possibility for such directors to be in a position of conflict over which company should pursue a particular acquisition opportunity. If any such conflict of interest arises, then a director who has a conflict must disclose the conflict to a meeting of our directors and must abstain from and will be unable to participate in discussion or decisions pertaining to the matter. In appropriate cases, Eldorado Gold will establish a special committee of independent directors to review a matter in which several directors, or management, may have a conflict. However, conflicts may not be readily apparent or only with the benefit of hindsight, and a conflicted director may exercise his or her judgment in a manner detrimental to Eldorado's interests.

Privacy Legislation

Eldorado is subject to privacy legislation in various countries in which we operate, including the European Union's General Data Protection Regulations ("GDPR") and Quebec's Act respecting the protection of personal information in the private sector ("Quebec Privacy Act"), which was recently amended by Bill 64, an Act to modernize legislative provisions as regards the protection of personal information ("Bill 64").

The GDPR is more stringent than its predecessor, the Data Protection Directive (Directive 95/46/EC). Similarly, Bill 64 brings significant and more stringent amendments to the Quebec Privacy Act and will come into force gradually over a 3-year period (some of which came into force in 2022 and 2023, and the remainder of which is expected to come into force in 2024). Eldorado is required to develop and implement programs that will evidence compliance with each, as applicable, or face significant fines and penalties for breaches. For example, companies that breach the GDPR can be fined up to 4% of their annual global turnover or €20 M, whichever is greater, while companies that breach the amended Québec Privacy Act can be fined up to 4% of their annual global turnover or C$25 M, whichever is greater. Such breaches may lead to costly fines and may have an adverse effect on governmental relations, our business, reputation, financial condition and the Eldorado Gold share price.

Reputational

Damage to Eldorado's reputation can be the result of the actual or perceived occurrence of any number of events, and could include any negative publicity, whether true or not. Although we believe that we operate in a manner that is respectful to all affected parties and take care in protecting our image and reputation, we do not have control over how we are perceived by others. Any reputation loss could result in decreased investor confidence and increased challenges in developing and maintaining community relations, which may have adverse effects on our business, results of operations, financial condition and the Eldorado Gold share price.

Competition

We compete for attractive mineral properties and projects with other entities that have substantial financial resources, operational experience, technical capabilities, skilled labour and political strengths,

98

including state owned and domestically domiciled entities, in some of the countries in which we now, or may in future wish to, conduct our business and operations.

We may not be able to prevail over these competitors in obtaining mineral properties that are producing or capable of producing metals, in attracting and retaining the skilled labour required to develop and operate our projects, or to compete effectively for merger and acquisition targets, or do so on terms we consider acceptable. This may limit our growth and our ability to replace or expand our mineral reserves and mineral resources and could have a material adverse effect on our business, results of operations, financial condition and the Eldorado Gold share price.

Senior Notes

On August 26, 2021, Eldorado Gold completed an offering of $ 500 M senior unsecured notes with a coupon rate of 6.25% due September 1, 2029 (the “Notes”). The Notes pay interest semi-annually on March 1 and September 1, which began on March 1, 2022. The Notes are unsecured and are guaranteed by Eldorado Gold (Netherlands) B.V., Eldorado Québec, SG and Tüprag, all wholly-owned subsidiaries of the Company.

Indenture

The Notes are governed by an Indenture dated August 26, 2021 among Eldorado Gold, the guarantor subsidiaries as noted above, Computershare Trust Company, N.A., as U.S. Trustee and Computershare Trust Company of Canada, as Canadian Trustee.

Under the Indenture, the Notes are redeemable by the Company in whole or in part, for cash:

a.At any time prior to September 1, 2024 at a redemption price equal to the sum of 100% of the aggregate principal amount of the Notes, plus accrued and unpaid interest, and plus a premium equal to (a) the greater of 1% of the principal amount of the Notes to be redeemed and (b) the excess, if any, of (i) the present value of (A) the redemption price of such Notes on September 1, 2024 plus (B) all required interest payments on such Notes through September 1, 2024, computed using a discount rate equal to the Treasury Rate plus 50 basis points, over (ii) the then-outstanding principal amount of such Notes.

b.At any time prior to September 1, 2024 up to 40% of the original principal amount of the Notes with the net cash proceeds of one or more equity offerings at a redemption price equal to 106.25% of the aggregate principal amount of the Notes redeemed, plus accrued and unpaid interest.

c.On and after the dates provided below, at the redemption prices, expressed as a percentage of principal amount of the Notes to be redeemed, set forth below, plus accrued and unpaid interest on the Notes:

September 1, 2024    103.125%

September 1, 2025    101.563%

September 1, 2026 and thereafter    100.000%

If Eldorado Gold sells certain of its assets or experiences specific kinds of changes in control, Eldorado Gold must offer to purchase the Notes.The Notes are Eldorado Gold’s and each guarantor’s senior unsecured obligations and rank equally in right of payment with any of Eldorado Gold’s and each guarantor’s existing and future senior indebtedness, and senior in right of payment to any of Eldorado Gold’s and each guarantor’s existing and future subordinated debt. The Notes are also effectively subordinated to any of Eldorado Gold’s and the guarantor’s existing and future secured indebtedness to the extent of the value of the collateral securing such debt. In addition, the Notes are structurally subordinated to the liabilities of Eldorado Gold’s non-guarantor subsidiaries.

The Indenture contains covenants that restrict, among other things, the ability of the Company to make distributions in certain circumstances and sales of material assets, in each case, subject to certain conditions. The Company was in compliance with these covenants at December 31, 2023. For full details of the terms of the Notes, see the Indenture, which is filed under Eldorado Gold’s profile on SEDAR+ at www.sedarplus.com.

Ratings

As of the date of this AIF, the Notes have credit ratings of B3 by Moody’s, BB- by S&P and B+ by Fitch.

Moody’s credit ratings are on a rating scale that ranges from AAA to C, which represents the range from highest to lowest quality of such securities rated. A rating of B by Moody’s is the sixth highest of nine categories and denotes obligations judged to be speculative are subject to high credit risk. The addition of a 1, 2 or 3 modifier after a rating indicates the relative standing within a particular rating category. The modifier 1 indicates that the issue ranks in the higher end of its generic rating category, the modifier 2 indicates a mid-range ranking and the modifier 3 indicates a ranking in the lower end of that generic rating category.

S&P’s credit ratings are on a rating scale that ranges from AAA to D, which represents the range from highest to lowest quality. A credit rating of BB by S&P is the fifth highest of ten categories. According to the S&P rating system, an obligor with debt securities rated BB is less vulnerable in the near-term, but faces major ongoing uncertainties to adverse business, financial or economic conditions. The addition of a plus (+) or minus (-) designation after the rating indicates the relative standing within a particular rating category.

101

Fitch’s credit ratings are on a scale that ranges from AAA to D, which represents the range from highest to lowest quality. A credit rating of B is the sixth highest of eleven categories. B ratings indicate that material default risk is present, but a limited margin of safety remains, and that financial commitments are currently being met; however, capacity for continued payment is vulnerable to deterioration in the business and economic environment. The addition of a plus (+) or minus (-) sign show relative standing within a particular rating category.

Credit ratings for the Notes do not directly address any risk other than credit risk. The credit ratings assigned by the rating agencies are not recommendations to purchase, hold or sell securities nor do the ratings comment on market price or suitability for a particular investor. There is no assurance that any rating will remain in effect for any given period of time or that any rating will not be revised or withdrawn entirely by a rating agency in the future if, in its judgment, circumstances so warrant.

Eldorado paid fees to each of Moody’s, S&P and Fitch for the credit ratings rendered in respect of the Notes. In addition to annual monitoring fees for the Notes, additional payments are made in respect of other services provided in connection with various rating advisory services.

Senior Secured Credit Facility

On October 15, 2021, the Company entered into a $250 M amended and restated fourth senior secured credit facility (the "Fourth ARCA") with an option to increase the available credit by $100 M through an accordion feature, and with a maturity date of October 15, 2025. As at December 31, 2023, the Company is in compliance with covenants related to the Fourth ARCA and no amounts were drawn.

In September 2022, the Fourth ARCA was amended to replace the London Inter-Bank Offered Rate with a benchmark rate based on the Secured Overnight Financing Rate. The amendment to the Fourth ARCA also permitted the revolving credit facility to be used to provide a bank issued letter of credit (“Project Letter of Credit”) in favour of the lenders under the Mandate Letter, and introduced Euro availability for the Project Letter of Credit. For details of the terms of the Fourth ARCA, see a copy of the Fourth ARCA as filed under Eldorado Gold’s profile on SEDAR+ at www.sedarplus.com.

Project Financing Facility

On December 15, 2022, the Company announced that it had entered into the €680.4 M project financing facility ("Term Facility") for the development of the Skouries Project. The Term Facility will provide 80% of the expected future funding required to complete the Skouries Project and includes up to €200 M of funds from the Greek Recovery and Resilience Facility (the "RRF"). The Term Facility is non-recourse to the Company and the collateral securing the Term Facility covers the Skouries Project and the Hellas operating assets.

The Company commenced its first drawdown on the Term Facility in the second quarter of 2023. The Term Facility is structured to provide 80% of the funding required to complete the Skouries Project, with the remaining 20% to be funded by the Company. This amount of the Company's investment undertaking for the Skouries project was initially fully backstopped by a letter of credit from the Company's Project Letter of Credit, which was subsequently reduced over time as the Company injected equity into Hellas Gold to fund the 20% undertaking. The proceeds of the EBRD Private Placement (CDN$ 81.5 M) which closed subsequently in the third quarter of 2023 will be credited against the Company’s 20% equity funding commitment.

The Term Facility includes the following components:

i.€480.4 M commercial loan;

ii.€100 M initial RRF loan; and

iii.€100 M additional RRF loan.

The Term Facility also provides a €30 M revolving credit facility to fund reimbursable VAT expenditures relating to the Skouries Project.

The project financing further includes, in addition to the Term Facility, a Contingent Overrun Facility for an additional 10% of capital costs, funded by the lenders and Hellas Gold in the same proportion as the Term Facility.

102

The interest rates of the facility are as follows:

i.Commercial loan: Variable interest rate of 6.86% at December 31, 2023 (comprised of six-months EURIBOR plus a fixed margin) until project completion, followed by a 0.20% reduction of the fixed margin at project completion. 70% of the variable rate exposure is hedged through an interest rate swap for the term of the facility.

ii.Initial RRF loan: Fixed interest rate of 3.04% for the term of the facility.

iii.Additional RRF loan: Fixed interest rate of 4.06% for the term of the facility.

As required under the Term Facility, Hellas Gold entered into various hedging contracts in April 2023, including hedging limited volumes of gold and copper production, hedging a portion of its foreign exchange exposure and an interest rate swap (as noted above).

The Term Facility can be drawn up to the earlier of: March 31, 2026, or August 26, 2026 (if the deferral option is exercised) or three months after “Project Completion date”. There is a seven-year repayment schedule with the first semi-annual installment payments commencing on June 30, 2026, and ending December 31, 2032.

Dividend Policy

The Board of Directors established a dividend policy in May 2010 and Eldorado Gold declared its first dividend of C$ 0.05 per common share. Any dividend payment, if declared, is expected to be derived from a dividend fund calculated on an amount, determined at the discretion of the Board of Directors at the time of any decision to pay a dividend, multiplied by the number of ounces of gold sold by Eldorado Gold in the preceding two quarters. In 2011, the Board of Directors amended the dividend policy to provide additional step-ups as the average realized gold price increases. The Board of Directors further amended the dividend policy in 2013 to revise the gradation of the fixed dollar amounts per ounce of gold sold.

The amount of the dividend fund will be divided among all the issued Eldorado Gold common shares to yield the dividend payable per share. Accordingly, the calculation of any dividends, if declared, will also be dependent on gold prices, among other things.

The declaration and payment of dividends is at the sole discretion of the Board of Directors, and is subject to and dependent upon, among other things: the financial condition of and outlook for the Company, general business conditions, satisfaction of all applicable legal and regulatory restrictions regarding the payment of dividends by Eldorado Gold and the Company’s cash flow and financing needs.

The Company has not declared dividends in the last three years.

The Company’s senior notes and Fourth ARCA contain certain restrictive covenants that may, in certain circumstances, limit its ability to pay dividends or make other distributions. See “Risk factors in our business” – “Current and Future Operating Restrictions”.

111

Cease Trade Orders, Bankruptcies, Penalties or Sanctions

In the last 10 years none of Eldorado Gold’s directors, executive officers or, to our knowledge, Material Shareholders has personally or has been a director or executive officer (while, or within a year of, acting in that capacity) of any Company (including ours) that has become bankrupt, made a proposal under legislation relating to bankruptcy or insolvency, been subject to or instituted any proceedings, arrangement of compromise with creditors, or had a receiver, receiver manager or trustee appointed to hold its assets, or the assets of that person.

None of Eldorado Gold’s directors or executive officers are, or have been within the last 10 years, a director, chief executive officer or chief financial officer of any company that was subject to a cease trade order, an order similar to a cease trade order, or an order that denied the relevant company access to any exemption under securities legislation that was in effect for a period of more than 30 consecutive days that was issued while the director was acting in that capacity, or that was issued after the director was no longer acting in that capacity, and which resulted from an event that occurred while that person was acting in that capacity.

None of our directors, executive officers or, to our knowledge, Material Shareholders have been subject to any penalties or sanctions imposed by a court or regulatory body, or have entered into a settlement agreement with any securities regulatory authority since December 31, 2000.

Conflicts of Interest

To the best of Eldorado Gold’s knowledge, it is not aware of any existing or potential conflicts of interest between it, or any of its directors or officers, which have not been disclosed to the Board of Directors, except that some of them serve as directors and officers of other public companies. It is therefore possible that there could arise a conflict between their duties as a director or officer of Eldorado Gold and their duties for other companies.

Eldorado Gold’s directors and officers are aware of the laws governing accountability of directors and officers for corporate opportunity. They understand they are required to disclose any conflicts of interest under the CBCA and are expected to govern themselves to the best of their ability according to the laws in effect.

The Board of Directors takes appropriate measures to exercise independent judgment when considering any transactions and agreements. If a director has a material interest, the director is obligated to excuse himself or herself from the appropriate portions of the Board of Directors and committee meetings so the directors can discuss the issue openly and candidly.

Material Contracts

Other than the Fourth ARCA, the Indenture, and the Term Facility agreement, we did not enter into any material contract within the last financial year, or in a prior financial year that is still in effect.

Interest of Experts

We rely on experts to audit our financial statements, prepare our mineral reserve and resource estimates and prepare our technical reports.

Our auditor is KPMG LLP. They have confirmed that with respect to Eldorado that they are independent within the meaning of the relevant rules and related interpretations prescribed by the relevant professional bodies in Canada and any applicable legislation or regulations, and also that they are independent accountants with respect to Eldorado under all relevant US professional and regulatory standards.

We list the people who have prepared our mineral reserve and resource estimates under “Mineral Reserves and Resources” starting on page 62 and the Qualified Persons responsible for our technical disclosure and/or reports under each of our properties.

None of these people or their employers have directly or indirectly, any material interest, or beneficial interest in the property of the Company or securities of Eldorado Gold or any of our affiliates or associated parties, other than those experts that are employed by us. The experts employed by us each own less than 1% of our securities.

112

Interest of Management and Others in Material Transactions

Other than as otherwise described in this AIF and our annual MD&A we are not aware of any transactions in our three most recently completed financial years, or during the current financial year, that has had or is reasonably expected to have a material effect on us where any of the following had a direct or indirect material interest:

◦any of our directors or executive officers, or those of our subsidiaries.

◦a person or company that beneficially owns, controls or directs, directly or indirectly, more than 10% of our voting securities; or

◦any associate or affiliate of the above.

We did not rely on any available exemptions in fiscal 2023 to meet our disclosure obligations for the year.

Legal Proceedings and Regulatory Actions

Litigation

Greece - Environmental Impact Assessment (EIA) Decision

As disclosed in “Risk Factors - Permits”, in Q2 2023, Hellas Gold obtained a modification and time extension (up to 2038) of the Kassandra Mines environmental terms approval (previously defined as the “2023 Environmental Terms Approval”) which covers the expansion of the Olympias processing facility and the Stratoni port modernization. In June 2023, local associations and residents filed an appeal for the annulment of the 2023 Environmental Terms Approval, claiming legal grounds relating to the Investment Agreement, and requesting that the provisions concerning the independent environmental auditor and certain environmental provisions be annulled. Hellas Gold has filed an intervention, and the hearing is expected to occur in 2024. In the case of a partial or full annulment of the 2023 Environmental Terms Approval, the 2011 Environmental Terms (as applicable in 2023) would still be valid on the relevant chapters. However, any provisions in the 2023 Environmental Terms not covered by the 2011 Environmental Terms (as applicable in 2023) would be subject to a new approval process.

In addition to the litigation brought against Hellas Gold described in this section titled “Litigation”, which is referred to as being applicable to all the Kassandra Mines, Hellas Gold is, from time to time, subject to and involved in various complaints, claims, investigations, proceedings and legal proceedings arising in the ordinary course of business, including, but not limited to, licenses, permits, supplies, services, employment and tax. Eldorado Gold and Hellas Gold cannot reasonably predict the likelihood or outcome of these actions.

For further description of all of our risks, see section entitled “Risk Factors in Our Business”.

Other than what has been disclosed above, we are not aware of any material legal proceedings which we are a party to or that involve our property, nor are we aware of any being considered.

We have not had any penalties or sanctions imposed by a court or regulatory body relating to securities legislation or regulatory requirements, or by a court or regulatory body that would be considered important to a reasonable investor in making an investment decision. We have also never been involved in a settlement agreement with a court relating to securities legislation or with a securities regulatory authority.

“heapleaching” is the process of stacking ore in a heap on an impermeable pad and percolating a solution through the ore that contains a leaching agent such as cyanide. The gold that leaches from the ore into the solution is recovered from the solution by carbon absorption or precipitation. After adding the leaching agent, the solution is then recycled to the heap to effect further leaching.

“HDPE” is high density polyethylene and is used as an impermeable geomembrane for heap leaching.

“hostrock” is the body of rock in which mineralization of economic interest occurs.

“HPGR” is high-pressure grinding roll

“HQ” denotes a specific diameter of diamond drill core, namely 63.5 mm.

“metallurgy” is the science of extracting metals from ores by mechanical and chemical processes and preparing them for use.

“mill” is a plant where ore is crushed and ground to expose metals or minerals of economic value, which then undergo physical and/or chemical treatment to extract the valuable metals or minerals.

“Mineral Reserve” is the economically mineable part of a Measured and/or Indicated Mineral Resource. It includes diluting materials and allowances for losses, which may occur when the material is mined or extracted and is defined by studies at Pre-Feasibility or Feasibility level as appropriate that include application of Modifying Factors. Such studies demonstrate that, at the time of reporting, extraction could reasonably be justified. The reference point at which Mineral Reserves are defined, usually the point where the ore is delivered to the processing plant, must be stated. It is important that, in all situations where the reference point is different, such as for a saleable product, a clarifying statement is included to ensure that the reader is fully informed as to what is being reported. The public disclosure of a Mineral Reserve must be demonstrated by a Pre-Feasibility Study or Feasibility Study.

a.“Proven Mineral Reserve” (Proved Mineral Reserve) is the economically mineable part of a Measured Mineral Resource. A Proven Mineral Reserve implies a high degree of confidence in the Modifying Factors.

b.“Probable Mineral Reserve” is the economically mineable part of an Indicated, and in some         circumstances, a Measured Mineral Resource. The confidence in the Modifying Factors applying to a Probable Mineral Reserve is lower than that applying to a Proven Mineral Reserve.

“Mineral Resource” is a concentration or occurrence of solid material of economic interest in or on the Earth’s crust in such form, grade or quality and quantity that there are reasonable prospects for eventual economic extraction. The location, quantity, grade or quality, continuity and other geological characteristics of a Mineral Resource are known, estimated or interpreted from specific geological evidence and knowledge, including sampling.

a.“Measured Mineral Resource” is that part of a Mineral Resource for which quantity, grade or quality, densities, shape, and physical characteristics are estimated with confidence sufficient to allow the application of Modifying Factors to support detailed mine planning and final evaluation of the economic viability of the deposit. Geological evidence is derived from detailed and reliable exploration, sampling and testing and is sufficient to confirm geological and grade or quality continuity between points of observation. A Measured Mineral Resource has a higher level of confidence than that applying to either an Indicated Mineral Resource or an Inferred Mineral Resource. It may be converted to a Proven Mineral Reserve or to a Probable Mineral Reserve.

b.“Indicated Mineral Resource” is that part of a Mineral Resource for which quantity, grade or quality, densities, shape and physical characteristics are estimated with sufficient confidence to allow the application of Modifying Factors in sufficient detail to support mine planning and evaluation of the economic viability of the deposit. Geological evidence is derived from adequately detailed and reliable exploration, sampling and testing and is sufficient to assume geological and grade or quality continuity between points of observation. An Indicated Mineral Resource has a lower level of confidence than that applying to a Measured Mineral Resource and may only be converted to a Probable Mineral Reserve.

c.“Inferred Mineral Resource” is that part of a Mineral Resource for which quantity and grade or quality are estimated on the basis of limited geological evidence and sampling. Geological evidence is sufficient to imply but not verify geological and grade or quality continuity. An Inferred Mineral Resource has a lower level of confidence than that applying to an Indicated Mineral Resource and must not be converted to a Mineral Reserve. It is reasonably expected that the majority of Inferred Mineral Resources could be upgraded to Indicated Mineral Resources with continued exploration.

“mineralization” is the rock containing minerals or metals of potential economic interest.

“mm” is a millimetre.

“monzonite” is a coarse-grained intrusive rock containing less than 10 percent quartz.

“ounce” or “oz” is a troy ounce, equal to 31.103 grams.

“pastefill” refers to a blended material that is used to fill open stopes or voids in the underground operations. This material may contain rock, tailings material, sand and cement.

“Pb” is the chemical symbol for lead.

“PEIA” is a preliminary environmental impact assessment.

“pH” is a measure of the acidity of a material.

“phyllite” is a metamorphic rock containing fine-grained, planar-oriented mica minerals. This orientation imparts a layering to the rock.

“QA” is quality assurance.

“QC” is quality control.

“QMX” is QMX Gold Corporation.

“ramp” is an inclined underground tunnel that provides access for mining or a connection between the levels of a mine.

“recovery” is a multiple disciplinary term. Its main usage in this report refers to metallurgical recovery, stated as a percentage, to indicate the proportion of valuable material obtained in the processing of an ore. It is also used to imply a type of mineral process. The term also has application in mining where it refers to the proportion of ore extracted by the mining method and sent to the mineral process facility. Core recovery refers to the percentage of rock retrieved by diamond drilling.

“ROM” pertains to the ore that has been mined but not crushed.

“SAG” is a semi-autogenous grinding, a method of grinding rock into fine powder whereby the grinding media consist of larger chunks of rocks and steel balls.

“tailings” is the material that remains after all metals or minerals of economic interest have been removed from ore during milling.

“TMF” refers to a tailings management facility. These facilities are designed to store process tailings for the long term. Process tailings might have potentially reactive materials and if so, would then be stored in a lined facility.

“tonne” is a metric tonne: 1,000 kilograms or 2,204.6 pounds.

“TSX” is the Toronto Stock Exchange.
