Rio Grande Resources Discovers High-Grade Gold and Silver at Winston Project

Rio Grande Resources Ltd., a mining exploration company, announced significant findings from its recently completed Phase Two surface sampling program at the Winston Gold-Silver Project in New Mexico. The program, which took place over seven days in May 2026, revealed high-grade results, including channel samples with up to 46.3 g/t gold and 1,030 g/t silver from the Poverty Creek area. These results align with previous explorations that identified multiple mineralized structural corridors.

CEO Jason Barnard stated that the program enhanced their confidence in the project, emphasizing the discovery of multiple vein systems. The integration of detailed structural mapping with sampling has improved the understanding of these systems, aiding the preparatory work for the inaugural Phase 1 drill program.

Channel sampling returned some of the highest grades, with channel D showing 46.3 g/t gold and 1,030 g/t silver. The program also involved rock chip and grab sampling, marking several structural corridors with high-grade mineralization. Rio Grande continues assessing the site, aiming to unlock its full potential through upcoming drilling operations.
