Wedoany.com Report-Oct. 17, Endeavour Silver  has commenced commercial production at its Terronera silver-gold mine in Jalisco, Mexico, with plans to process 360,000 tonnes of ore over the next six months. The milestone was announced on Thursday, October 16, 2025, following a successful commissioning phase.

Terronera silver-gold mine in Jalisco, Mexico.

Since operations started on July 1, 2025, the Terronera mine has operated for 100 days with only eight days of downtime, consistently exceeding 90% of its designed 2,000-tonne-per-day capacity and achieving at least 90% of projected metal recoveries since mid-August. This performance strengthens Endeavour’s position as a growing mid-tier silver producer.

“Bringing Terronera into commercial production marks a huge milestone for Endeavour Silver and represents a truly transformational moment in our company’s history,” said chief executive officer Dan Dickson. “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.”

“We expect Terronera to be a significant contributor to free cash flow generation and silver-equivalent production growth for Endeavour,” said Alex Terentiew, a mining analyst at National Bank Financial, in a note on Thursday. He noted that the mine accounts for 42% of his 2026 cash flow estimate and 37% of his silver-equivalent production projection.

The Terronera mine includes the Terronera and La Luz underground deposits, extracted using long-hole stoping and cut-and-fill methods. A recent feasibility study projects annual production of 4 million ounces of silver and 38,000 ounces of gold over a 10-year mine life. Over the next six months, the mine is expected to process ore with average grades of 122 g/t silver and 2.52 g/t gold, with higher-grade zones anticipated by mid-2026 to further enhance output. Endeavour plans to issue its 2026 production and cost guidance for Terronera in January.

Following the announcement, Endeavour’s shares rose 7.1% to C$14.26 in Toronto on Thursday afternoon, reaching their highest intraday level since the company’s founding in 2004. This increased the company’s market value to approximately C$4.2 billion, with its stock more than doubling since the start of 2025.

With Terronera now operational, Endeavour Silver operates four mines across Mexico and Peru, alongside an active exploration portfolio in Mexico, Chile, and the United States. The company’s focus on sustainable growth and efficient operations positions it to contribute significantly to the global silver and gold markets.
