Rio Grande Resources Confirms High-Grade Gold and Silver Including 46.3 g/t Gold and 1,030 g/t Silver in Channel Samples as it Advances Toward Phase 1 Drilling at its Winston Project, New Mexico

May 2026 surface sampling produced strong precious-metal assay results, including up to 46.3 g/t gold and 1,030 g/t silver in channel samples. Grab samples returned up to 67.1 g/t gold, while rock chip samples showed up to 26.1 g/t gold and 348 g/t silver. Overall, the findings are a constructive exploration signal but are not yet a confirmed resource or production update.
