An update from Rio Grande Resources Ltd ( (TSE:RGR) ) is now available.

Rio Grande Resources has completed its 2025 geological field program at the Winston Gold–Silver Project in New Mexico, confirming a well-developed low-sulfidation epithermal vein system that hosts multiple mineralized trends and extensive historic mine workings. The program, conducted by Dahrouge Geological Consulting, included detailed mapping, 72 channel and rock-chip samples, the mapping of 52 mineralized vein outcrops, and documentation of 58 previously under-reported historic workings, leading to the identification of several priority areas—such as Ivanhoe–Emporia, Little Granite Mine, and Poverty Creek—for follow-up work. Geological interpretation indicates vein continuity over hundreds of metres to more than a kilometre, with mineralization remaining open along strike and at depth, supporting the view that Winston may represent a district-scale system rather than isolated structures. The company now plans to integrate the new data into an updated geological and structural model, consider additional geophysical surveys, improve site access, and design a targeted drill program focused on vein intersections and zones with strong epithermal textures, potentially enhancing the project’s exploration upside and strategic value for stakeholders.
