Past-producing Ivanhoe, Emporia and Little Granite establish a long history of high-grade gold-silver mineralization across Winston.
Modern exploration is expanding beyond the historic mine areas, with Poverty Creek emerging as an important new target within a broader structural system.
Integrated geological work has advanced priority targets toward Phase 1 drilling — the next major step in testing Winston below surface.
The Winston Project is situated in the northwestern region of Sierra County, New Mexico, about 45 miles northwest of the town of Truth or Consequences, within the Chloride Sub-District of the Black Range Mountains.
The area was a past major producer with current strong potential for district-scale discovery.
Multiple drill-ready targets on both patented and un-patented claims.
Located 45 miles northwest of Truth or Consequences in an area with significant gold and silver production history.
Ivanhoe • Emporia • Little Granite
Three past-producing mine areas provide Winston with more than a century of geological and mining history and a foundation of known gold-silver mineralization.
Modern sampling has reaffirmed high-grade mineralization across the property, including peak earlier results of 66.5 g/t Au at Little Granite, 46.1 g/t Au at Emporia and 26.8 g/t Au at Ivanhoe.
Systematic channel sampling returned up to 46.3 g/t Au + 1,030 g/t Ag, while structural mapping traced multiple mineralized vein corridors beyond the historic mine areas.
Initial drill pad locations established at Poverty Creek as Rio Grande advances Winston toward its first drill program in decades.
Rio Grande controls 100% of Winston, providing direct exposure to exploration success across the broader project.
Winston is not dependent on a single target — historic mine areas and newer targets provide several opportunities for exploration success across the property.
Historic workings are being evaluated with systematic sampling, structural mapping, airborne geophysics and integrated geological targeting.
Historic workings and drilling are now being combined with modern sampling, structural mapping and property-wide airborne geophysics — creating a substantially richer exploration dataset than existed during earlier exploration.
Past-producing high-grade gold-silver mine areas provide historical geological proof
Poverty Creek demonstrates that Winston’s opportunity extends beyond the historic workings.
Sampling, structural mapping and airborne geophysics are building a modern geological model across Winston.
Dahrouge Geological Consulting completed the 2026 mapping and sampling work, supporting a disciplined, data-driven targeting model.
Phase 1 drilling provides the opportunity to begin testing the modern geological model below surface
Subject to certain underlying royalties, Rio Grande Resources controls a 100% interest in the Winston Project.
Comprised of three historic past-producing high-grade gold-silver mines on 147 unpatented lode mining claims.
The four (4) Little Granite Claims (the “LG Claims”) and (2) patented mining claims, Ivanhoe and Emporia (the “Ivanhoe/Emporia Claims”), for a total of 149 total mining claims across 3,000+ acres.
