SANTACRUZ SILVER ADVANCES SORACAYA PROJECT TOWARD PRODUCTION WITH PRELIMINARY MINE PLAN AND PERMITTING

Santacruz Silver Mining Ltd. has initiated development activities and the pursuit of full production permitting at its wholly owned Soracaya project, located in the Potosi department, Bolivia. These activities mark a key step toward advancing the project to a production decision.

Arturo Prestamo, executive chairman and chief executive officer of Santacruz, commented: "With the preliminary mine plan in place and the permitting process under way, Soracaya is emerging as a cornerstone growth project for Santacruz in Bolivia. Its high-grade resource, strategic location and synergies with existing operations give us confidence in its ability to deliver long-term value for shareholders and stakeholders alike."

Mr. Prestamo continued: "By advancing the project and preparing for future construction, we are laying the foundation to add another producing mine to our portfolio while we keep a disciplined approach to cost control and operations improvements. Our work at Soracaya represents a clear commitment to Santacruz's long-term growth and expansion in Bolivia."

Soracaya is a high-grade, silver-rich project, featuring mineralization along reactivated faults with replacement and brecciated sulphides, geological characteristics typical of some of the world's most productive silver deposits. Since 1999, more than 29.6 kilometres of drilling across 90-plus holes has provided extensive geological data, supporting robust resource modelling and preliminary mine planning.

With this resources base in place, Santacruz is now focused on completing permitting and advancing Soracaya toward full construction, an important step in the company's strategy to grow its Bolivian production base. Details regarding the full construction decision will be shared at a later stage.
