Endeavour Silver Corp. ("Endeavour" or the "Company") (NYSE: EXK; TSX: EDR) is pleased to announce that it has entered into an agreement with a syndicate of underwriters (the "Underwriters") led by BMO Capital Markets, pursuant to which the Underwriters have agreed to buy on a bought-deal basis 15,825,000 common shares of the Company (the "Common Shares"), at a price of US$4.60 per Common Share for aggregate gross proceeds of approximately US$73 million (the "Offering"). The Company has granted the Underwriters an option, exercisable in whole or in part for a period of 30 days following the closing of the Offering, to purchase up to an additional 10% of the Common Shares offered under the Offering to cover over-allotments, if any.

The principal objectives for use of the net proceeds of the Offering are for general working capital and the advancement of the Pitarrilla Project.

The Offering is expected to close on or about November 27, 2024 and is subject to Endeavour receiving all necessary regulatory approvals and the approval of the Toronto Stock Exchange and the New York Stock Exchange.

The Common Shares will be offered in all provinces of Canada (except Quebec) pursuant to a short form base shelf prospectus (the "Base Shelf Prospectus") as accompanied by a prospectus supplement (the "Prospectus Supplement") and will be offered in the United States pursuant to a prospectus supplement to a base shelf prospectus forming part of the Company's registration statement on Form F-10 (together with any amendments thereto, the "Registration Statement") registering the Common Shares under the United States Securities Act of 1933, as amended, pursuant to the Multi-Jurisdictional Disclosure System adopted by the United States and Canada. The final prospectus supplement will be filed with the securities commissions and other similar regulatory authorities in each of the provinces of Canada, except Quebec, and the United States, within two business days. The Common Shares may also be offered on a private placement basis in certain jurisdictions outside of Canada and the United States pursuant to applicable prospectus exemptions. However, there will not be any sale of Common Shares in any province, state or jurisdiction in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the applicable securities laws of such province, state or jurisdiction.
