Endeavour Silver said it has achieved commercial production at the Terronera Mine located in Jalisco state, Mexico.
The declaration of commercial production at Terronera comes after a successful commissioning phase during which both mining and processing operations were ramped up to consistently exceed an average of 90 percent of the designed nameplate capacity of 2,000 tonnes per day, while also achieving at least 90 percent of the projected metal recoveries.
Terronera has demonstrated remarkable progress, operating for 100 days since July 1, 2025, with eight days of downtime, and has sustained strong metal recoveries since mid-August. This achievement marks an important milestone that positions Endeavour for continued growth and long-term success.
“Bringing Terronera into commercial production marks a huge milestone for Endeavour Silver and represents a truly transformational moment in our company’s history. This achievement not only reinforces our commitment to sustainable growth but also positions Endeavour as a leading mid-tier silver producer with a solid foundation for future expansion,” said Dan Dickson, chief executive officer.
The company forecasts throughput of approximately 360,000 tonnes over the next six months, with average grades estimated at 122 g/t silver and 2.52 g/t gold. Higher grade zones are scheduled to be accessed by mid-2026, which is expected to further enhance production. Management plans to issue annualized 2026 production and cost guidance for the Terronera mine in January 2026.
Endeavour Silver is a mid-tier precious metals company with a strong commitment to sustainable and responsible mining practices. With operations in Mexico and Peru, and the development of the new cornerstone mine in Jalisco state, the company aims to contribute positively to the mining industry and the communities in which it operates. In addition, Endeavour has a portfolio of exploration projects in Mexico, Chile, and the United States to facilitate its goal to become a premier senior silver producer.
