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

Executive Summary

• The U.S. Geological Survey added boron to its 2025 List of Critical Minerals, placing the element alongside lithium and 58 other commodities eligible for strategic government funding and policy support.
• Canter Resources’ Columbus Lithium‑Boron Project now benefits from heightened eligibility for federal financing, streamlined permitting and increased investor interest as a domestic source of a newly‑designated critical mineral.
• Recent field work returned high‑grade boron values (up to 30,000 ppm in solid samples and up to 1,730 mg/L total B in shallow brines), underscoring the project’s potential to supply both lithium and boron for advanced manufacturing, EV batteries and national security applications.

Key Details

• Critical Mineral Designation: Boron is officially listed on the USGS 2025 Critical Minerals List, expanding the pool of commodities eligible for U.S. government funding and strategic support.
• Project Proximity to Funding: The Department of Energy recently announced a nearly $1 billion funding package for Ioneer’s Rhyolite Ridge Lithium‑Boron Project, located ~27 km south of Canter’s Columbus project.
• Geological Extent: Historic and modern drilling indicate a lithium‑boron system covering an estimated 8 km × 6.5 km area within the Columbus Basin.
• High‑Grade Boron Results:
• Solid sediment samples: up to 30,000 ppm B.
• Shallow brine samples: up to 1,730 mg/L total B (820 mg/L dissolved).
• Trend Analysis: Geochemical mapping shows a clear northward increase in boron concentrations, aligning with Canter’s two highest‑priority drill targets.
• Lithium Potential at Depth: Structural analogies to Nevada’s Clayton Valley suggest deeper aquifers could host higher‑grade lithium‑boron brines, offering upside for future drilling programs.
• Strategic Implications: The critical mineral status is expected to improve the Columbus project’s eligibility for federal funding, accelerate permitting, and attract institutional capital focused on domestic supply chain security.
• Qualified Person Review: Technical information reviewed and approved by Eric Saderholm, P.Geo., Director & Technical Advisor (QP) under NI 43‑101.

Notable Quotes

“We believe Columbus features one of North America's most prospective untapped sources of both lithium and boron… 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.” – Joness Lang, CEO, Canter Resources Corp.
