Endeavour Silver’s Terronera mine achieves commercial production in Mexico
The operations achieved at least 90% of the anticipated metal recoveries.

October 17, 2025

Endeavour Silver has announced that the Terronera mine in Jalisco state, Mexico, achieved commercial production status earlier this month following a successful commissioning phase.

During commissioning, both mining and processing operations were scaled up to surpass an average of 90% of the designed nameplate capacity of 2,000 tonnes (t) per day.

Additionally, the operations achieved at least 90% of the anticipated metal recoveries.

Endeavour Silver said that Terronera has made significant progress, having been operational for 100 days since 1 July 2025, with only eight days of downtime.

The mine is said to have maintained strong metal recoveries since mid-August.

Endeavour Silver chief executive officer Dan Dickson said: “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.”

The company expects throughput of around 360,000t over the upcoming six months, with average grades projected to be 122 grams per tonne (g/t) silver and 2.52g/t gold.

Access to higher-grade zones is expected by mid-2026, potentially enhancing production further.

The management intends to announce the annualised production and cost guidance for the Terronera mine in January 2026.

Endeavour is a mid-level silver producer, operating four active mines in Mexico and Peru.
