Canter Resources Highlights Boron's Addition

to U.S. Critical Minerals List-Unlocking

Strategic Advantages for the Columbus

Lithium-Boron Project in Nevada

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.

About Canter Resources Corp.

Canter Resources Corp. is a junior mineral exploration company advancing the Columbus Lithium-Boron

Project and the Railroad Valley (RV) Lithium-Boron Project in Nevada, USA. 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 metals targeting

database to generate a portfolio of high-quality projects with the aim of defining mineral resources that

support the technology and domestic clean energy supply chains in North America.
