Rio Grande Resources

What Rio Grande Resources does

Rio Grande Resources Ltd. is a pre-revenue mineral exploration company focused on the ~3,000-acre Winston Gold-Silver Project in the Black Range of Sierra County, New Mexico. The asset comprises 147 unpatented BLM mining claims, 2 patented lode claims (Ivanhoe and Emporia), and 4 Little Granite lode claims covering three historic past-producing high-grade gold-silver mines within a low-sulfidation epithermal vein system along the Paymaster Fault corridor. The company does not currently produce minerals and generates no operating revenue; its activity is limited to surface sampling, geological mapping, airborne geophysics, and 3D modeling to define drill targets ahead of a planned Phase 1 drill program.

The company was incorporated in July 2024 and became a standalone public entity on January 31, 2025, after Foremost Clean Energy Ltd. (NASDAQ: FMST, CSE: FAT) spun out its Winston Property via a Plan of Arrangement, distributing two Rio Grande shares for each Foremost share held and retaining an approximately 19.95% ownership stake (the largest single shareholder). Denison Mines Corp. (TSX: DML, NYSE American: DNN) acquired a 15.31% stake in connection with the spin-out. Rio Grande's common shares began trading on the Canadian Securities Exchange (CSE: RGR) on February 7, 2025, and subsequently listed on the OTCQB Venture Market (RGRLF) and the Frankfurt Stock Exchange (488).

The business model is capital-intensive exploration rather than commercial sales: the company is funded primarily through equity raises (a non-brokered private placement of up to ~$1.33M CAD was announced in May 2025 with insider participation) and deploys funds into technical work programs executed by partners such as Dahrouge Geological Consulting and Precision GeoSurveys. Surface sampling has returned high-grade results, including up to 66.2 g/t gold and 830 g/t silver along the Paymaster Fault corridor, up to 41.2 g/t gold and 1,435 g/t silver from the Poverty Creek Trend, and historical peak values of 66.5 g/t gold and 4,610 g/t silver at Little Granite. The company employs between 1 and 10 people and is led by CEO Jason Barnard, President Christina Barnard, CFO Curtis Bouwman, and Non-Executive Chairman Richard Silas.

Products and services

• Winston Gold-Silver Project A ~3,000-acre drill-ready property in the Black Range Mountains of Sierra County, New Mexico, encompassing three historic past-producing gold and silver mines (Ivanhoe, Emporia, and Little Granite) with 147 unpatented BLM mining claims and 2 patented lode mining claims. The property hosts high-grade, low-sulfidation epithermal gold-silver veins within the Paymaster Fault corridor.
• Ivanhoe Mine A past-producing gold-silver mine consisting of 2 patented lode claims with exclusive ownership of the land and its resources. Historic production included peak values of 26.8 g/t gold and 1,670 g/t silver. The Ivanhoe Emporia Vein structure is 3-5m wide at surface and was historically developed to a depth of 384 feet.
• Emporia Mine A past-producing gold-silver mine with historic sampling returning peak values of 46.1 g/t gold and 517 g/t silver. Part of the Ivanhoe and Emporia patented claims providing exclusive ownership of the land and its resources.
• Little Granite Mine A 100%-owned past-producing gold mine consisting of 4 lode mining claims. Past sampling included peak values of 66.5 g/t gold and 4,610 g/t silver. The main vein has been traced for over 200 meters by past drilling and remains open along strike and at depth.

Emerging players

• Foremost Clean Energy Ltd. Sister spin-out and largest shareholder (~19.95%) of Rio Grande following the January 2025 Plan of Arrangement. Both are CSE-listed exploration companies led by overlapping management and share a common technical DNA, although Foremost is focused on uranium/critical minerals rather than gold and silver.

Others

• Denison Mines Corp. 15.31% strategic shareholder of Rio Grande following the spin-out. Denison is a uranium-focused intermediate, not a direct precious-metals peer, but its meaningful equity stake and exploration-finance pedigree make it a directly comparable governance/financing counterparty for micro-cap resource spin-outs.

Direct peers

• Aya Gold & Silver Inc. CSE-listed silver-gold developer advancing epithermal-style precious-metals assets in Morocco with both exploration upside and early production. Closely comparable stage, jurisdiction profile (Morocco vs. New Mexico), and silver-gold exploration thesis to Rio Grande.
• Vizsla Silver Corp. Silver-gold explorer-developer focused on the Panuco epithermal vein district in Mexico, with high-grade drill results and a similar CSE/TSX-listed junior profile. Useful peer for benchmarking exploration-stage precious-metals valuations and drill-program value creation.
• MAG Silver Corp. Silver-focused explorer-developer with a flagship high-grade epithermal asset (Juanicipio, Mexico) operated in partnership with a major. Represents a comparable silver-rich epithermal thesis and provides a benchmark for resource-stage precious-metals valuations.
• Defiance Silver Corp. TSX Venture-listed silver-gold explorer with assets in Mexico, including epithermal vein systems. Closely aligned with Rio Grande on size, single-asset focus, exploration stage, and silver-gold epithermal thesis.
• Reyna Silver Corp. Junior silver-gold explorer with a district-scale epithermal/carbonate-replacement project in Mexico. Comparable to Rio Grande in scale, stage, and precious-metals exploration focus, making it a useful peer for benchmarking early-stage resource stories.

Broad incumbents

• Hecla Mining Company: Established silver and gold producer with multiple U.S. and Mexican operations. Provides a long-term benchmark for what a successful silver-gold exploration pipeline can become, although at vastly larger scale than Rio Grande.
• Coeur Mining Inc. Mid-tier precious-metals producer operating silver and gold mines across North America, including epithermal-style systems. Relevant broad incumbent for understanding how advanced exploration assets in the Southwest U.S. are valued and developed.
• First Majestic Silver Corp. Pure-play silver and gold producer with multiple Mexican operations targeting epithermal vein systems. A relevant broad incumbent peer that demonstrates the strategic value of district-scale silver-gold portfolios in the same geological belt as Rio Grande's exploration thesis.
