CANTER RESOURCES HIGHLIGHTS BORON'S ADDITION TO U.S. CRITICAL MINERALS LIST-UNLOCKING STRATEGIC ADVANTAGES FOR THE COLUMBUS LITHIUM-BORON PROJECT IN NEVADA

Canter Resources Corp. has noted boron has been added to the U.S. Geological Survey's 2025 list of critical minerals. This significant development elevates boron alongside lithium and 58 additional commodities eligible for strategic government financing 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 has a new classification as a critical mineral, which is expected to further accelerate domestic investment in boron projects across the United States, 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, chief executive officer 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 and lithium highlights:

• Widespread boron system across a large footprint: Historic and modern drilling/sampling confirms a broad lithium-boron mineralized system extending across an estimated eight-kilometre-by-6.5-kilometre 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 parts per million B in solid sediment samples, complemented by up to 1,730 milligrams per litre B (total) and 820 milligrams per litre (dissolved) in shallow brine samples, demonstrating strong enrichment in both clastic units and active brine generation (see news release dated Oct. 15, 2024). These results align with historical accounts of late 1800s borate brine production in the district.
• 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.

Note: Mineralization at nearby or adjacent properties is not necessarily indicative of mineralization hosted at the company's Columbus project.

About Canter Resources Corp.

Canter Resources is a junior mineral exploration company advancing the Columbus lithium-boron project and the Railroad Valley lithium-boron project in Nevada, United States. The company is completing a phased drilling approach at Columbus to test highly prospective brine targets at varying depths for lithium-boron enrichment and plans to leverage the company's critical metal targeting database to generate a portfolio of high-quality projects with the aim of defining mineral resources that support the and domestic clean energy supply chains in North America.
