American West Metals Accelerates Storm Copper Project Exploration Programme

Storm Copper Project: Deep Drilling Success Confirms Large-Scale Potential

American West Metals has announced significant breakthroughs at its Storm Copper Project in Canada, with new diamond drilling and geophysical results providing compelling evidence of a potentially substantial copper system at depth. The latest results include the intersection of copper mineralisation at the Cinto project and the identification of multiple large conductive anomalies through advanced geophysical surveys.

Major Breakthrough at Cyclone Deeps Target

The first diamond drill hole of the 2025 program has delivered a significant development, intersecting approximately 47 metres of visual sediment-hosted copper mineralisation below the existing Cyclone Deposit. Drill hole ST25-02 targeted the Allen Bay Formation within the Central Graben at approximately 280m depth, revealing:

• Multiple zones of visual sulphide mineralisation between 284m-319m and 368m-380m
• Mineralisation hosted in fractured dolomudstones with veinlets and matrix breccias
• Similar style and mineralogy to the edges of the near-surface Cyclone Deposit

This substantial thickness of mineralisation suggests American West Metals may be on the edge of another large copper deposit beneath the existing resource, potentially enhancing the scale of the Storm Copper Project significantly.

"The style and mineralogy of the copper mineralisation in ST25-02 as well as the features of the host geology are similar to that of the edges of the near-surface Cyclone Deposit, and is typical of sedimentary-hosted copper systems. This mineralogy and the thickness of the intersection indicate that we may be on the edge of another large copper deposit," said Dave O'Neill, Managing Director of American West Metals.

Geophysical Survey Reveals Multiple New Copper Targets

Phase 1 of the innovative Mobile MagnetoTellurics (MMT) survey has been completed along the Midway-Storm-Tornado corridor, with preliminary results identifying multiple large conductive targets:

Critically, the MMT survey successfully detected the known Cyclone Deposit, validating the technique's effectiveness for identifying copper mineralisation at the Storm Copper Project. This technology is providing American West Metals with powerful new targeting capabilities, particularly for deeper exploration where previous geophysical methods had limitations.

Comprehensive 2025 Exploration Program Advancing Rapidly

The 2025 exploration program at the American West Metals Storm Copper Project is progressing efficiently with:

• 12 RC drill holes completed to date across resource upgrade and exploration targets
• Resource category upgrade drilling at Thunder, Lightning Ridge, and Corona deposits
• Exploration drilling at The Gap and southern graben areas
• Phase 1 MMT survey completed with approximately 1,320 line-km flown
• Government support through CAD$250,000 in funding from Nunavut's DIG program

Furthermore, the company has been making progress similar to recent drilling at New South Wales copper-gold prospect, showing the increased industry focus on copper exploration.

Understanding Sediment-Hosted Copper Systems

Sediment-hosted copper deposits represent an important class of copper resources globally, accounting for approximately 20-25% of worldwide copper production. These deposits form in sedimentary basins where copper-bearing fluids move through permeable rocks and deposit copper minerals at favourable horizons or structural traps.

The mineralisation at the Storm Copper Project displays characteristic features of sediment-hosted copper systems:

• Hosted within dolomitic sedimentary rocks
• Strong structural control on mineralisation
• Chalcocite as the primary copper mineral with lesser chalcopyrite and bornite
• Lateral and vertical zonation of mineralisation

This deposit style is comparable to world-class copper districts like the Kupferschiefer in Europe and Central African Copperbelt, which are known for their large size and high grades.

Investment Thesis: A World-Class Copper Project Emerging

American West Metals is positioning the Storm Copper Project as a significant copper development opportunity at a time when copper demand is forecast to outstrip supply due to global electrification and decarbonisation trends.

Several key factors make the Storm Copper Project compelling for investors:

1. Expanding Resource Potential: The new drilling and geophysical results strongly suggest the existing resource could be substantially expanded both at depth and along strike.

2. High-Grade, Near-Surface Mineralisation: The current resource features high-grade copper that starts at surface, supporting potential for low strip-ratio open pit mining.

3. Simple Metallurgy: Previous metallurgical testing has demonstrated excellent sorting and processing characteristics, with potential for low-cost processing options.

4. Infrastructure Advantages: Despite its remote location, the project benefits from nearby tidewater access, facilitating potential future shipping of concentrate.

5. Strong Government Support: The Nunavut government has demonstrated support through funding, highlighting the project's importance to regional development.

In addition, recent gold discovery at the Hurricane project by other explorers shows the region's broader potential for diverse mineral systems.

Why Investors Should Follow American West Metals

The Storm Copper Project represents a rare opportunity to invest in a potentially world-class copper discovery at a time when new copper discoveries are becoming increasingly scarce globally. With assay results pending from multiple drill holes and additional MMT survey results forthcoming, the company is entering a period of high news flow that could significantly enhance project valuation.

The combination of near-surface, high-grade resources already defined, plus the emerging deeper mineralisation potential demonstrated by the latest drilling, positions the American West Metals Storm Copper Project as one of the most promising emerging copper projects in North America. For investors seeking exposure to the critical minerals needed for the global energy transition, American West Metals offers a compelling opportunity with significant discovery upside.

As the mining industry shifts focus to critical minerals, projects like Storm Copper are gaining attention alongside other exciting developments such as uranium exploration in Namibia and drilling at the Oasis uranium project, reflecting broader industry trends toward energy transition metals.
