Rio Grande Resources Completes Mapping at Winston Project

Rio Grande Resources Ltd. has finalized its Phase 2 field sampling and structural mapping program at the Winston Gold-Silver Project in New Mexico. Through collaboration with Dahrouge Geological Consulting USA Ltd., the company has enhanced its geological understanding of mineralized vein trends across the property as they gear up for their Phase 1 drill program.

During the seven-day effort in May 2026, 91 samples were collected. Structural mapping added 307 new data points, improving insights into the project's vein trends and corridors. Identification of multiple steeply dipping vein corridors and structural intersections highlights the continuity of mineralized trends across key areas.

CEO Jason Barnard emphasized the increased confidence in the project's potential for a larger district-scale epithermal system. Pending assay results will integrate with existing data to refine drill targets, aiming to benefit the company and its shareholders.
