**EXHIBIT 99.1**

**Endeavour Silver Launches Offering of Convertible Senior Notes**

**VANCOUVER, British Columbia, Dec. 01, 2025 (GLOBE NEWSWIRE) -- Endeavour Silver Corp. ("Endeavour" or the "Company") (NYSE: EXK; TSX: EDR)** announces that it is offering US$300 million aggregate principal amount of unsecured convertible senior notes due 2031 (the "Notes") pursuant to private placement exemptions (the "Offering"). Endeavour expects to grant the initial purchasers of the Notes an option to purchase up to an additional US$45 million aggregate principal amount of Notes.

Endeavour intends to use the net proceeds of the Offering to repay its senior secured debt facility with ING Capital LLC (together with ING Bank N.V.) and Societe Generale (the "Credit Facility"), to fund the advancement of its Pitarrilla project located in Durango State, Mexico, and for general corporate purposes, including strategic opportunities.

The final terms of the Offering will be determined by Endeavour and the initial purchasers. The Notes will bear cash interest semi-annually at a fixed rate and will be convertible by holders into Endeavour common shares (the "Shares"). The Notes will be redeemable by Endeavour at its option in certain circumstances. Holders will have the right to require Endeavour to repurchase their Notes upon the occurrence of certain events.

The Offering is subject to customary closing conditions including approval of the Toronto Stock Exchange and the New York Stock Exchange.

The Notes and the Shares issuable upon the conversion thereof have not been and will not be registered under the U.S. Securities Act of 1933, as amended (the "Securities Act"), registered under any state securities laws, or qualified by a prospectus in Canada. The Notes and the Shares may not be offered or sold in the United States absent registration under the Securities Act or an applicable exemption from registration under the Securities Act. The Notes will be offered only to "qualified institutional buyers" (as defined in Rule 144A under the Securities Act) in the United States and outside of the United States in accordance with the requirements of Regulation S under the Securities Act. The Notes may not be offered or sold in Canada except pursuant to exemptions from the prospectus requirements of applicable Canadian provincial and territorial securities laws.

*This news release is neither an offer to sell nor the solicitation of an offer to buy the Notes or the Shares issuable upon the conversion thereof, and shall not constitute an offer to sell or solicitation of an offer to buy, or a sale of, the Notes or the Shares issuable upon the conversion thereof in any jurisdiction in which such offer, solicitation or sale is unlawful.*

**About Endeavour Silver –** Endeavour is a mid-tier silver producer with four operating mines in Mexico and Peru and a robust pipeline of exploration projects across Mexico, Chile, and the United States. With a proven track record of discovery, development, and responsible mining, Endeavour is driving organic growth and creating lasting value on its path to becoming a leading senior silver producer.
