The global supply chain for gallium, a designated critical mineral, remains highly concentrated, highlighting a broader market need for alternative supply sources. At Cerro de Pasco Resources, recent drilling results from the Quiulacocha Tailings Project have identified gallium concentrations. Additional project information is available at: pascoresources.com

Milestone at Quiulacocha: our continuous mini-pilot at SGS reproduced bench-scale results — ~94% silver and >92.5% sulphide recovery into a single high-grade concentrate, advancing a conceptual two-concentrate flowsheet. Full release + cautionary notes: pascoresources.com/_resource… $CDPR

Gallium is a critical building block for modern aerospace and defense technology. Offering superior performance over traditional materials, it is essential for everything from advanced guidance systems to satellite communications.
