2 ELDORADO GOLD | CODE OF ETHICS AND BUSINESS CONDUCT Message from CEO George Burns We value integrity – which means being honest and doing the right thing. This core value is central to the way we do business. We are all accountable for making ethically grounded decisions in our day-to-day work, including in how we treat one another. You can expect this of me, just as I expect it of you. Our Code of Ethics and Business Conduct (the “Code”), along with our Anti-Bribery and Corruption Policy (“ABC Policy”), clarify what is acceptable and what is not. Whenever something comes in conflict with our value of integrity, we expect people to speak up. This ties to another core value at Eldorado – courage. Ethics is more than a set of rules. It’s about communicating candidly and doing the right thing, even when it feels risky. Ethical behaviour includes avoiding actual or apparent conflicts of interest between your personal and professional relationships – and speaking up if you see this conflict in others. I believe strongly that the most sustainable companies are fundamentally ethical companies. As an ethical employer, we are committed to providing a safe and respectful work environment for all our people. We have zero tolerance for discrimination, harassment or abuse of any kind in the workplace, as further outlined in our Respectful Workplace Policy. By reading and following the Code in our daily interactions, each one of us is contributing to Eldorado’s reputation as an ethical employer and community partner wherever we operate around the world. Take the time to review the Code and reflect on your own behaviours and actions as an ethical individual. If you have any questions about the Code, seek advice from the individuals identified within it. If you become aware of any situations or conditions you believe may violate the Code, speak up. Tell your leader, record it through Eldorado’s Whistleblower Reporting Line, or report via the means identified in this Code. You can be confident that you will not face retaliation of any kind for reports made in good faith. We each play an essential role in upholding a culture of integrity across Eldorado. (Signed) George Burns Chief Executive Officer VALUES Courage We embrace the unknown and face challenges head on Collaboration We succeed together Drive We persevere through adversity, remaining committed to delivering on our promises Integrity We are honest and do the right thing Agility We continuously assess, adapt and navigate to find solutions

ELDORADO GOLD | CODE OF ETHICS AND BUSINESS CONDUCT 3 Our Code of Ethics and Business Conduct Eldorado’s Code of Ethics and Business Conduct applies to you and anyone doing work for Eldorado, our subsidiar-ies and our affiliates (collectively referred to as “Eldorado”). It describes our expectations for acting ethically in all situations and making choices that are in line with the highest standards of integrity and business conduct. The expectations described in this Code of Ethics and Business Conduct and the other applicable policies referred to in the Code (collectively, the “Code”), including your responsibility for reporting suspected violations, are subject to all applicable laws and regulations under which Eldorado operates. If this Code is in conflict with any applicable law, the law takes priority. WHO DOES THIS CODE APPLY TO? This Code applies to all Eldorado employees, directors and officers. It also applies to anyone who conducts business on behalf of Eldorado, such as our contractors, consultants and suppliers. In this Code, anyone to whom the Code applies is sometimes referred to as “you”. We provide a copy of the Code to everyone who works for or with Eldorado. Each year, you must read the Code. Annually, directors, officers, country managers who are responsible for overseeing employees in foreign jurisdictions where we operate and other key decision makers within Eldorado must sign a personal statement (called an Annual Compliance Certificate) saying that such individuals understand the Code and will follow it. In some circumstances, the Code may be explained to you by your manager or supervisor. This person will be responsible for confirming that you have heard and understood the information in the Code. There are additional expectations for our Board of Directors and for our individual directors. These expectations can be found in the Board of Directors’ Terms of Reference available on our website.. WHO OVERSEES THIS CODE? Eldorado’s Board of Directors created the standards of business and personal conduct described in this Code to provide clear guidelines and expectations for all Eldorado employees and others doing work for Eldorado. Any waiver of this Code for the benefit of a director or executive officer may only be granted by the Board of Directors or a designated committee of the Board. Where such a waiver constitutes a material departure from the Code, the Company will comply with applicable disclosure obligations under securities laws, which may include the filing of a material change report that outlines the nature and circumstances of the waiver. The Chair of the Board’s Audit Committee and our Executive Vice President and General Counsel will monitor compliance with the Code. In this capacity, they report directly to the Audit Committee and our Board of Directors. QUESTIONS? You may have questions about this Code or a particular situation you have experienced. We encourage you to speak with your manager or supervisor about any issues, without fear of retribution. You can also discuss your questions or concerns about this Code, or any other applicable business practice, with our Executive Vice President and General Counsel or any other member of the Eldorado Legal and Compliance team, using the contact details set out in the Reporting Contacts section below. If you are aware that someone is violating this Code, you must report this misconduct. Please see the section How to report a suspected Code violation for more information.

4 ELDORADO GOLD | CODE OF ETHICS AND BUSINESS CONDUCT We Comply with All Laws and Regulations Eldorado has operations around the world, with each operation subject to the laws and regulations of its jurisdiction. We also comply with international standards regarding human rights, safety, workplace practices and environmental management. In addition to complying with this Code, you must also comply with all laws and governmental regulations that apply to your role with Eldorado. If you break the law, you and/or Eldorado may face criminal or civil charges. If at any time you are uncertain about the application or interpretation of a law, regulation or policy, you should consult your manager or supervisor or seek the opinion of the Eldorado Legal and Compliance team. Q&A Q: Some of the policies in this Code (like those regarding anti-bribery under our ABC Policy and non-discriminatory workplace practices) are more stringent than the laws in the country where I work. Do I need to follow the Code and other Eldorado policies or can I just follow the law in my country? A: In this case, you must follow this Code and other Eldorado policies. Eldorado operates to the most stringent practices outlined in law or in the Code. This means that if the law is more stringent than what we have outlined in this Code, you must follow the law. If the Code is more stringent than the law, you must follow the Code.

ELDORADO GOLD | CODE OF ETHICS AND BUSINESS CONDUCT 5 We Act with Honesty and Integrity We act fairly and honestly with integrity and accountability in all of our business relationships. As set out in our ABC Policy, an act of bribery or corruption – for instance, exchanging gifts or money to obtain a benefit for Eldorado or yourself, such as a contract or a favourable government action – violates our Code and ABC Policy and may result in civil or criminal sanctions against those involved and the company. WHAT ARE SOME EXAMPLES OF BRIBERY? Some examples of bribery and corruption include offering, promising, paying or authorizing any payment or thing of value to any person, directly or indirectly through or to a third party (e.g., a representative of government, a labour union, a customer or supplier), for the purpose of or in exchange for: • A person acting or failing to act in violation of a legal duty (e.g., a payment by an Eldorado employee to a government inspector to overlook a health or safety violation); • A person abusing or misusing their position (e.g., an Eldorado employee receiving a secret payment from a supplier in exchange for giving Eldorado business to that supplier); • Obtaining or retaining an advantage or benefit (including any permit, license, contract or concession) for Eldorado or any of its representatives, suppliers or agents (e.g., making a payment to a governmental official to issue an environmental permit); or • Inducing a public official to perform a non-discretionary activity more quickly or at all (e.g., giving a gift to a tax inspector to process an Eldorado tax return). The definitions of “public official” and “bribery” are very broad. If you have any questions about these definitions or the scope of the Code, consult with Eldorado’s Executive Vice-President and General Counsel. WHAT CAN WE DO TO PROTECT OURSELVES FROM ALLEGATIONS OF BRIBERY? To uphold Eldorado’s commitment to integrity and honesty, you should always: • Limit marketing and client entertainment expenditures to those that are necessary, prudent, job-related and consistent with our ABC Policy and the related Gifts and Entertainment Procedures. • Consult with the Company’s Executive Vice President and General Counsel before offering or providing any gift, entertainment or other benefit to a public official. • Use clear and precise communication in our contracts, marketing, disclosure documents and other public statements. • Ensure full and accurate disclosure when reporting all financial information, which includes completion of the Gifts and Entertainment Register. WHAT ABOUT GIFTS? • You are never allowed to give or receive a cash gift. • Receiving non-cash gifts, or giving them to customers, suppliers and others, is allowed in limited circumstances as described in the ABC Policy and in compliance with our Gift and Entertainment Procedures. • You are not allowed to offer or receive a gift, gratuity or entertainment that might, or might be perceived to, unfairly influence a business relationship. • Any gift offered or received should be reasonable in both frequency and value given the circumstances. A gift that may be perceived as an attempt to create an obligation or enticement for the recipient is inappropriate. • Business entertainment activities should also be reasonable in frequency and value, and be provided without expecting to receive a direct or indirect advantage or benefit of any kind, whether business or personal. • Gifts must be properly documented and recorded in our financial records. • You should not offer or give a gift, entertainment or other benefit if you think that doing so would contravene the ABC Policy or any law without first consulting Eldorado’s Executive Vice President and General Counsel. • You should consult the Gifts and Entertainment Procedures for guidance on approvals and on specific limits and processes. WHAT ABOUT CHARITABLE DONATIONS? Eldorado works hard to be a positive corporate citizen in the locations where we operate. Our investments in community organizations and initiatives are one way that we bring tangible benefits to improve the infrastructure, education levels and health of the communities near our sites. While we regularly donate to charitable organizations, we do not make contributions to a charity or other organization that would provide, directly or indirectly, a personal benefit to a government official or private individual.

6 ELDORADO GOLD | CODE OF ETHICS AND BUSINESS CONDUCT ARE POLITICAL DONATIONS ALLOWED? Eldorado may occasionally make limited political donations in the jurisdictions where we work and where it is legal and appropriate to do so. The CEO must approve all political donations. We acknowledge and support the right of individuals to participate in legitimate political activities. However, these activities should not be conducted on Eldorado time nor involve the use of any Eldorado resources. Individuals will not be reimbursed for personal political contributions. MORE INFORMATION Please review our ABC Policy and the Gifts and Entertainment Procedures carefully for more information on this topic.. If you have any questions about whether a gift or expense is allowed for a public official under the Code and ABC Policy, please contact our Executive Vice-President and General Counsel or any other member of our Legal and Compliance team. Q&A Q: Giving gifts is part of the local culture and is expected protocol during meetings. If I give or receive a gift when meeting with government officials or suppliers, does this count as bribery? A: Because of our strict rules about offering benefits to public officials, you should never offer or provide any gift, entertainment or other benefit without first consulting Eldorado’s Executive Vice President and General Counsel. Q: I’m often invited to sporting events or out for dinners by our business partners or suppliers. Am I allowed to accept these invitations? A: You can accept invitations if the invitations are for business related events and if they comply with our ABC Policy and the Gifts and Entertainment Procedures. A good question to ask yourself is “Would an impartial outsider think that attending this dinner or event is appropriate?” If you are unsure if accepting the invitation is appropriate, please speak with your manager or supervisor or a member of our Legal and Compliance team. Q: When is approval required for giving or receiving a gift? A: Approval is required when the value of the gift exceeds the threshold set out in the Gift and Entertainment Procedures, or when the gift could reasonably be perceived as influencing business judgment or creating a conflict of interest. In addition, you may need to consult with the Legal and Compliance team for gifts involving public officials.

ELDORADO GOLD | CODE OF ETHICS AND BUSINESS CONDUCT 7 We Avoid All Conflicts of Interest A conflict of interest is a situation where there is a real or perceived tension between your interests and the interests of Eldorado. This includes any familial and/or romantic relationship between one employee and another employee, prospective employee, contractor or supplier that involves any direct or indirect administrative or operational authority. Even if you think you can separate your personal interests from the situation and decision-making process, this is still a conflict of interest as there could be the perception that you are influenced by your personal interests. We must avoid all situations where there is a real or perceived conflict of interest. WHAT SHOULD I DO IF I THINK THERE IS A CONFLICT OF INTEREST? You must always share any good faith concerns you have about a real or perceived conflict of interest. If you think there might be a conflict of interest, please contact our Executive Vice-President and General Counsel or any member of our Legal and Compliance team. They will determine if there is a conflict of interest and the required course of action. WHAT ARE SOME EXAMPLES OF CONFLICTS OF INTEREST? Here are some examples of situations where there could be a real or perceived conflict of interest: • You hire a contractor or supplier for Eldorado and a member of your family or household works for the contractor or supplier. This could include a spouse, child, parent, sibling, relative by blood or marriage or other person sharing your home, whether or not they are your legal relatives. • You are employed by or acting as a consultant for a business that sells products to or performs services for Eldorado. • You own a part of a company that does business with Eldorado. • You use Eldorado’s corporate property or information for your own personal gain. • You supervise a family member or someone with whom you are in a romantic relationship (either directly or indirectly). • You approve the compensation decisions within your chain of command for a family member or someone with whom you are in a romantic relationship. Q&A Q: I’ve been asked to work on a small project as a consultant with another mining company operating in a country where Eldorado doesn’t have any operations. Is this a conflict of interest? A: Yes, this is a conflict of interest. As an Eldorado employee, you are not allowed to act as a consultant for other mining companies. Q: Is it a conflict of interest if I am in a family or romantic relationship with someone who reports to me? A: Yes, this is a conflict of interest. You should disclose the relationship to your immediate supervisor. Although your relationship is a private matter, to avoid allegations of favouritism, your supervisor may recommend adjusting the reporting or supervisory relationship. Q: I have an ownership interest in a company that provides goods or services to Eldorado. Is that a conflict of interest? A: Yes, this is a conflict of interest because your financial interest in the supplier conflicts with your obligation to always act in the best interest of Eldorado.

8 ELDORADO GOLD | CODE OF ETHICS AND BUSINESS CONDUCT We Protect Confidential Information As part of your work with Eldorado, you may be entrusted with confidential information about our company, our business and our business partners.

Even after you stop working for Eldorado, you are not allowed to share confidential information with others. WHAT IS INSIDER TRADING? As an Eldorado employee, you might have access to material information about Eldorado that is not publicly available and that, if known, could affect the market price or value of Eldorado’s securities.

Eldorado may also impose specific “blackout” periods during which you are not allowed to buy, sell or exercise our securities. The prohibitions on insider trading are not limited to Eldorado securities.

You are also not allowed to share material information with others unless required or permitted by law. You must comply with the prohibitions above which are detailed in the Insider Trading Policy.

This creates a workplace where employees: • are treated with dignity and respect; • are comfortable asking questions about ethical conduct; • are hired, promoted, disciplined or terminated based on appropriate business factors, such as performance or organizational needs, and not because of their race, sex, age or other factors unrelated to our business; and • do not fear retaliation if they report misconduct.

Q&A Q: One of my colleagues often comments on my body and makes sexual comments that are inappropriate. I have to work with this person as part of my team and I don’t want to upset our group dynamics. However, I also don’t like feeling uncomfortable at work. What should I do? A: The behaviour of your colleague is unacceptable: You have the right to a workplace that is free from discrimination and harassment. You should report this misconduct to your manager, Human Resources, through a local worker voice channel, or through the reporting channels described in the section How to report a suspected Code violation.
