Rio Grande Resources (OTCQB:RGRLF) completed its Phase 2 sampling and structural mapping program at the Winston gold-silver project in New Mexico. The work included 91 rock and channel samples and 307 new structural data points, identifying multiple steeply dipping vein corridors, structural intersections and widespread low-sulfidation epithermal quartz textures across key target areas.
The integrated dataset is expected to refine drill targets ahead of a planned Phase 1 drill program, with assay results pending. Rio Grande Resources also appointed Andrew Brown as Corporate Secretary, effective May 25, 2026.
Rio Grande Resources (OTCQB:RGRLF, CSE:RGR) reported results of its first annual general meeting held May 6, 2026. Shareholders approved fixing the board at three directors, re-elected Jason Barnard, Richard Silas and Raymond Strafehl, appointed Davidson & Company LLP as auditor, and approved an amended stock incentive plan.
The Board re-appointed executive officers and confirmed committee memberships following the AGM.
Rio Grande Resources (OTCQB:RGRLF) initiated a second phase of field sampling and mapping at the Winston Gold-Silver Project in Sierra County, New Mexico, ahead of a planned Phase 1 drill program.
Fieldwork by Dahrouge will include ~seven days of structural mapping and systematic sampling in mid-May 2026 to refine high-confidence drill targets by integrating recent high-grade surface samples (up to 41.2 g/t Au and 1,435 g/t Ag) with airborne magnetic and radiometric survey results.
Rio Grande Resources (OTCQB:RGRLF) reported results from a 384 line-km airborne magnetic and radiometric survey at the Winston Gold-Silver Project, New Mexico, identifying multiple linear magnetic trends, discrete magnetic disruptions, and radiometric responses that highlight potential hydrothermal alteration zones.
The company will integrate these data with prior surface samples (up to 41.2 g/t Au and 1,435 g/t Ag), complete ground validation, and refine drill targets. Christina Barnard was appointed President; Jason Barnard remains CEO and director.
Rio Grande Resources (OTCQB:RGRLF) reported results from a 384 line-km airborne magnetic and radiometric survey at the Winston Gold-Silver Project, New Mexico, and appointed Christina Barnard as President on April 30, 2026. The survey identified structural trends, discrete magnetic disruptions, and radiometric anomalies that may indicate hydrothermal alteration, and will be integrated with prior surface samples (up to 41.2 g/t Au and 1,435 g/t Ag) to refine follow-up sampling and drill targets. The company plans detailed interpretation, ground validation, and drill-target refinement; a Qualified Person reviewed the technical information, while historical results remain unverified.
Rio Grande Resources (OTCQB:RGRLF) engaged Precision GeoSurveys to fly a high-resolution airborne magnetic survey over 100% of the 19.2 km² Winston gold-silver project in New Mexico, starting in late February 2026. The survey (50 m line spacing, ~427 line‑km planned) will support structural interpretation after recent surface assays up to 41.2 g/t Au and 1,435 g/t Ag and a confirmed ~2.0 km mineralized corridor.
Data will be processed into magnetic intensity and derivative maps and integrated with mapping and assays to prioritize drill targets.
Rio Grande Resources (OTCQB:RGRLF) reported high-grade surface assay results from its December 2025 campaign at the Winston Project, New Mexico, including gold up to 41.2 g/t and silver up to 1,435 g/t. A total of 72 samples (including 11 channels) were collected, and the company interprets an approximate 2.0 km north-south mineralized strike within the claim block.
The program defined a new "Poverty Creek Trend", identified multiple structurally controlled corridors, and outlined priority targets for follow-up mapping and potential drill permitting.
Rio Grande Resources (OTCQB: RGRLF) completed its 2025 geological field program at the Winston gold-silver project in Sierra County, New Mexico, from December 2–8, 2025. Work by Dahrouge included detailed mapping, targeted surface sampling, and compilation of historic mine workings to refine drill targets.
Key outputs: 72 samples collected, 52 mineralized outcrops mapped, and 58 historic mine workings documented. Mapping indicates low-sulfidation epithermal veins with textures typical of boiling zones and vein continuity from hundreds of metres to over 1 km, open along strike and at depth. Next steps include updated geological models, geophysics, and targeted drill planning.
Rio Grande Resources (OTCQB:RGRLF) engaged Dahrouge Geological Consulting under a Master Service Agreement to advance systematic exploration at its drill-ready ~3,000-acre Winston gold-silver project in the Black Range, Sierra County, New Mexico. Initial scope began in October 2025 and a comprehensive site visit and sampling program is scheduled for early December 2025 to validate historical data, map veins, channel sample exposures and build a 3D geologic model to define drill targets.
The company also appointed Harpreet Bajaj as corporate secretary and granted 30,000 options exercisable at $0.42 for three years plus 25,000 RSUs subject to vesting; all awards carry a statutory hold period of four months and one day.
