ENDEAVOUR SILVER HIGHLIGHTS PROGRESS ON ITS THREE-YEAR SUSTAINABILITY STRATEGY IN 2023 SUSTAINABILITY REPORT

Endeavour Silver Corp. has made further progress executing its 2022 to 2024 sustainability strategy, as outlined in the company's 2023 sustainability report, released today.

Entitled "Transformation in Motion," the report provides insights into Endeavour's sustainability performance and approach over 2023, including second-year progress highlights against the strategy.

"Since launching our 2022 to 2024 sustainability strategy two years ago, we have completed many significant initiatives and achieved key targets," stated Dan Dickson, chief executive officer of Endeavour. "In 2023, we transformed more commitments into meaningful impact across our sites and surrounding areas. With the ongoing construction of our flagship mine, Terronera, we're on the doorstep of a transformation that will bring us closer to becoming a premier silver producer -- and our sustainability initiatives have helped set us up for this exciting future."

Endeavour's 2022 to 2024 sustainability strategy is centred around three pillars:

• People -- increasing positive social impacts for people in the workplace and in the communities where Endeavour operates.
• Planet -- elevating the company's environmental stewardship to reduce negative impacts, protect ecosystems and support environmental sustainability.
• Business -- operating a trusted, well-performing business by further strengthening the critical foundations that create long-term organizational sustainability.
