Canter Resources Highlights Boron's Addition to U.S. Critical Minerals List-Unlocking Strategic Advantages for the Columbus Lithium-Boron Project in Nevada

Rhea-AI Summary

Canter Resources (OTC: CNRCF) announced that boron was added to the USGS 2025 List of Critical Minerals, increasing eligibility for strategic federal support for boron projects and elevating the strategic profile of the Columbus Lithium-Boron Project in Nevada.

Key disclosed facts: an estimated 8 km by 6.5 km lithium-boron mineralized footprint; surface boron up to 30,000 ppm; shallow brine values up to 1,730 mg/L total and 820 mg/L dissolved; proximity (~27 km) to Ioneer’s Rhyolite Ridge and a recent nearly $1 billion DOE funding package for that project. Canter targets exploration and potential discovery exposure in H1 2026.

Positive

• Boron added to USGS 2025 Critical Minerals List
• Estimated 8 km by 6.5 km lithium-boron mineralized footprint
• Surface sediment boron up to 30,000 ppm
• Shallow brine results up to 1,730 mg/L total B and 820 mg/L dissolved B
• Proximity (~27 km) to DOE-backed Rhyolite Ridge project with nearly $1B funding

Negative

• Historic nearby production and neighboring projects do not guarantee Columbus mineralization
• Key higher-grade lithium at depth is unproven

Vancouver, British Columbia--(Newsfile Corp. - November 17, 2025) - Canter Resources Corp. (CSE: CRC) (OTC Pink: CNRCF) (FSE: 6010) ("Canter" or the "Company") Canter Resources is pleased to announce the addition of boron ("B") to the United States Geological Survey's (USGS) 2025 List of Critical Minerals. This significant development elevates boron alongside lithium and fifty-eight additional commodities eligible for strategic government funding and policy support due to the vital role they play in the technology, energy, national security, and advanced manufacturing sectors.​

Long considered a strategic mineral by the Department of War, boron's new classification as a critical mineral is expected to further accelerate domestic investment in boron projects across the U.S., as seen with the recent nearly $1 billion U.S. Department of Energy funding package supporting Ioneer's Rhyolite Ridge Lithium-Boron Project, located just 27 kilometres south of Canter's own Columbus Lithium-Boron Project in Nevada.

Joness Lang, CEO of Canter, commented: "We believe Columbus features one of North America's most prospective untapped sources of both lithium and boron, two minerals now both recognized as critical by the U.S. government. Boron is essential for high-strength glass, permanent magnets, fertilizers and EV battery chemistries, making it increasingly strategic for decarbonization and U.S. critical minerals supply security. The need for more domestic supply of critical minerals has never been more salient, and we look forward to providing shareholders with exploration and discovery exposure during H1/2026."

Boron & Lithium Highlights

• Widespread Boron System Across a Large Footprint: Historic and modern drilling/sampling confirm a broad lithium-boron mineralized system extending across an estimated 8 km by 6.5 km area of the Columbus Basin, with both sediment-hosted and brine-hosted B anomalism indicating a significant, basin-scale evaporative footprint.

• High-Grade Boron Values in Multiple Media: Field programs returned up to 30,000 ppm B in solid sediment samples, complemented by up to 1,730 mg/L B (Total) and 820 mg/L (Dissolved) in shallow brine samples, demonstrating strong enrichment in both clastic units and active brine generation (see news release dated October 15, 2024 and Figure 1). These results align with historical accounts of late-1800s borate brine production in the district (see Image 1).

• Clear Northerly Trend in Increasing B Grades: Geochemical mapping and stratigraphic correlations reveal a progressive increase in boron concentrations toward the northern structural corridor, coincident with the Company's two highest-priority targets for future exploration well drilling. This trend supports the presence of a concentrated, structurally focused boron-enriched brine domain.

• Strategic Importance Elevated by U.S. Critical Mineral Status: Boron's addition to the 2025 U.S. Critical Minerals List enhances the strategic potential of the Columbus Project, positioning Canter to benefit from improved eligibility for federal funding, streamlined permitting pathways, and heightened institutional interest in domestic boron supply.

• Clear Potential for Higher-Grade Lithium at Depth: Structural and hydrological similarities between the Columbus Basin and Clayton Valley-Nevada's premier lithium-producing basin-indicate that deeper aquifers may host more concentrated lithium-boron brines. With shallow zones already returning substantial anomalous values and evidence of structural traps within a closed hydrological system, Columbus exhibits the hallmarks of a maturing lithium-boron brine basin capable of delivering significantly higher grades at depth.
