VANCOUVER, British Columbia, Aug. 16, 2026 (GLOBE NEWSWIRE) -- Endeavour Silver Corp. (“Endeavour” or the “Company”) (NYSE: EXK; TSX: EDR) reports that operations at its Terronera mine in Jalisco, Mexico have been temporarily suspended since August 12(th) as the result of an illegal blockade by members of the nearby Ejido community regarding their concerns over road maintenance, assistance with medical services and communications, control and access to water supply and increased financial assistance. To date, the blockade has remained peaceful, orderly and respectful.

The site remains staffed with a reduced workforce to support safety and security protocols and continues to be accessible for maintenance activities.

The Company has the ability to pursue legal action and will exercise all available legal remedies if this matter is prolonged.
