A New Chapter Begins: Terronera Mine Enters Commercial Production

We are proud to announce a major milestone in Endeavour Silver’s journey, the Terronera Mine, located in Jalisco, Mexico, is now in commercial production. This moment marks not only a significant achievement for our company, but a powerful step forward for sustainable mining development in Mexico.

Terronera, now Endeavour Silver’s flagship operation with the potential to significantly boost silver production both for Endeavour Silver and for Mexico. More than a project, Terronera represents the future of responsible mining and our next step toward becoming a senior silver producer. 

A Milestone Worth Celebrating

Reaching commercial production is the result of years of vision, planning, and collective effort. Since 2010, our teams have worked tirelessly to transform Terronera from a promising exploration project into a fully operating mine. 

From early exploration to construction and now full-scale operations, the path to this point has been defined by collaboration with local communities, regional partners, and our incredible team. 

We celebrate this milestone not only as a technical and economic achievement, but as a testament to our focus on integrity, investing in long-term growth, and delivering shareholder value.

Empowering Local Communities

Terronera has been developed with a strong emphasis on community engagement and regional development. As production ramps up, so does our ability to contribute directly to the local economy through:

  • Job creation and training programs
  • Support for local suppliers and businesses
  • Investment in infrastructure and community development initiatives
  • Environmental stewardship and sustainable practices

We believe mining can and should be a force for good, and our work in Jalisco is guided by that belief.

Analyst Tour 

As part of celebrating Terronera’s successful transition into commercial production, we recently welcomed a group of analysts for a site tour. It was an opportunity to showcase the progress, innovation, and teamwork behind Terronera’s development. We extend our appreciation to everyone who joined us on the visit, and a special thanks to our on-site team for their continued hard work and dedication in bringing this milestone project to life.

Shaping the Future of Silver Mining

With Terronera now operational, we are entering a new era for Endeavour Silver. One where we are positioned to be a key contributor to Mexico’s silver output and an industry leader. 

This mine strengthens our portfolio, enhances our production capacity, and furthers our mission to build a profitable and sustainable silver company that delivers long-term value for all stakeholders, from investors and employees to the communities where we operate.

Looking Ahead

Terronera is only the beginning of the next chapter. We will continue to apply our values of excellence, safety, transparency, and sustainability as we operate and grow. We are deeply grateful to our team, our partners, and the local community for bringing this vision to life.
