About Silver X

Silver X is a growing silver producer building a multi-asset, district-scale precious metals platform in Peru. The Company’s portfolio includes the Nueva Recuperada Project, a district-scale land package of 20,795 hectares with two mining units and over 200 exploration targets, as well as the recently acquired Pampas Project, which further enhances the Company’s scale and long-term growth potential.

Current production from the Tangana Mining Unit is increasing alongside the planned restart of the Plata, Red Silver and Blenda Rubia mines, supporting a path toward approximately 6 million AgEq ounces annually by 2029. The addition of the Pampas Project strengthens the Company’s asset base and reinforces its strategy of evolving into a scalable, district-wide multi-asset operator.

With existing production, scalable expansion opportunities, and significant exploration upside across multiple assets, Silver X is positioning itself as a next-generation silver company focused on growth, diversification, and long-term value creation.
