Item 5.Full Description of Material Change

On May 30, 2023, Eldorado announced that it had entered into agreements with respect to a C$81.5 million strategic investment in Eldorado by the EBRD. The investment is to be effected by way of the Private Placement. The proceeds of the Private Placement will be invested in the Skouries project in Northern Greece, and will be credited against the Company’s 20% equity funding commitment per the terms of the project financing facility that closed on April 5, 2023.

In addition, Eldorado also announced that it had entered into an agreement with BMO Capital Markets and National Bank Financial, on behalf of the Underwriters, pursuant to which the Underwriters agreed to purchase on a bought deal basis 10,400,000 Common Shares of the Company (the “Common Shares”) at the same price as the EBRD Private Placement of C$13.00 per Common Share, for gross proceeds of approximately C$135 million under the Offering. In addition, the Company granted the Underwriters the Over-Allotment Option. In the event that the option is exercised in its entirety, the aggregate gross proceeds of the Offering would be C$155 million. Proceeds from the Offering will be used to fund growth initiatives across the Company’s global portfolio, including some not currently contemplated within the Company’s five-year plan, as well as for general corporate and working capital purposes.

The Common Shares are being offered for sale pursuant to the Offering in all of the provinces and territories of Canada by way of a Canadian prospectus supplement to the Company’s Canadian short form base shelf prospectus dated May 18, 2023.

The Private Placement is expected to close on or about June 13, 2023 following completion of the Offering, and is not conditional on the closing of the Offering. The Private Placement is also subject to a number of customary conditions, including the approval of the Toronto Stock Exchange and New York Stock Exchange. In addition, and as part of the Private Placement, the Company and EBRD have entered into a Project Support Agreement, pursuant to which, amongst other things, the Company has agreed to provide EBRD with certain ongoing reporting rights regarding the development and operations of the Skouries Project, as well as customary anti-dilution rights with respect to its investment in the Company. All securities issued under the Private Placement will be subject to a hold period expiring four months and one day from the date of issuance.

Steven Reid (for 12,000 Common Shares), George Burns (for 25,000 Common Shares), Stephen Walker (for 10,000 Common Shares), Teresa Conway (for 2,500 Common Shares), Carissa Browning (for 2,000 Common Shares), Pamela Gibson (for 10,000 Common Shares), Catharine Farrow (for 7,500 Common Shares), Philip Yee (for 15,000 Common Shares), Frank Herbert (for 2,000 Common Shares), and Lynette Gould (for 1,500 Common Shares), each an insider of the Company by virtue of being a director and/or officer of the Company, subscribed for an aggregate of 87,500 Common Shares for aggregate consideration of $1,137,500 in connection with the Offering.

In addition, Helikon Investments Ltd., an insider by virtue of holding greater than 10% of the issued and outstanding Common Shares, purchased 3,150,000 Common Shares for aggregate consideration of $40,950,000, representing approximately 1.60% of the issued and outstanding common shares of the Company following the closing of the Offering of June 7, 2023.

The issuance of Common Shares to each above noted insider is considered related party transactions under Multilateral Instrument 61-101 Protection of Minority Security Holders in Special Transaction (“MI 61-101”).

The Company relied on exemptions from the formal valuation and minority approval requirements in sections 5.5(a) and 5.7(1)(a), respectively, of MI 61-101, in respect of such insider participation. The exemptions are based on the fact that neither the fair market value of the Common Shares, nor the fair market value of the entire Offering, insofar as it involves the insiders, exceeds 25% of the Company’s market capitalization. The Company did not file a material change report with respect to the participation of the insiders at least 21 days prior to the closing of the Offering as the insider participation was not determined at that time. The terms of the Offering and the agreements relating thereto were submitted to and unanimously approved by way of a resolution approved at a meeting of the Board of Directors of the Company.

This report shall not constitute an offer to sell or the solicitation of an offer to buy these securities, nor shall there be any sale of these securities in any state or jurisdiction in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such state or jurisdiction.
