Rio Grande Resources to survey gold-silver project in New Mexico using airborne magnets, following high-grade surface finds.

Rio Grande Resources will conduct a high-resolution airborne magnetic survey across its 19.2-square-kilometer Winston Gold-Silver Project in New Mexico starting late February 2026, using 50-meter line spacing to map subsurface structures. The survey, by Precision GeoSurveys Inc., follows high-grade surface sampling showing gold up to 41.2 g/t and silver up to 1,435 g/t, confirming a 2-kilometer-long mineralized corridor. Data will help identify faults, lithological contacts, and structural complexities along the Paymaster Fault to refine exploration targets for future drilling. Results will integrate with surface data to prioritize high-potential zones. A Qualified Person reviewed the technical content, though historical results were not independently verified. Updates will follow as data is processed.
