American West Metals Strikes Copper Gold with Record 27.3% Grades at Storm Project
American West Metals has delivered another standout drilling result from its Storm Copper Project in Canada, with assays revealing exceptional 27.3% copper grades at the flagship Cyclone deposit. These latest results continue to validate the company's strategic focus on high-grade, near-surface copper mineralisation that could support rapid development in North America's critical minerals landscape.
The recent drilling programme demonstrates the exceptional potential of this North American copper development, with results that exceed industry benchmarks. Moreover, these findings position American West Metals as a leading player in the critical minerals sector.
Diamond Drilling Delivers Exceptional High-Grade Copper Intercepts
The latest geotechnical and resource diamond drilling programme at Cyclone has exceeded expectations, with two diamond holes delivering substantial copper mineralisation outside current pit designs. These results demonstrate significant expansion potential for what is already the largest planned open pit at Storm.
Drill hole PFS-002 emerged as the standout performer, intercepting:
- 12.1m @ 5.6% Cu, 21g/t Ag from 70m depth
- Including 3.8m @ 8.1% Cu, 31g/t Ag from 72.7m
- With a spectacular 0.5m @ 27.3% Cu, 80g/t Ag from 76m
- Plus 2.3m @ 4.6% Cu, 21.8g/t Ag from 78.1m
Furthermore, Drill hole PFS-001 also delivered impressive results:
- 18.2m @ 1.1% Cu, 11g/t Ag from 30m depth
- Including 7.1m @ 2.2% Cu, 12g/t Ag from 33.4m
- Additional 7.5m @ 0.5% Cu, 3.8g/t Ag from 81m (outside current pit design)
| Hole ID | From (m) | To (m) | Interval (m) | Cu (%) | Ag (g/t) |
|---|---|---|---|---|---|
| PFS-002 | 70.0 | 82.1 | 12.1 | 5.6 | 21.0 |
| PFS-002 | 72.7 | 76.5 | 3.8 | 8.1 | 31.0 |
| PFS-002 | 76.0 | 76.5 | 0.5 | 27.3 | 80.0 |
| PFS-001 | 30.0 | 48.2 | 18.2 | 1.1 | 11.0 |
| PFS-001 | 33.4 | 40.5 | 7.1 | 2.2 | 12.0 |
"The drilling at Cyclone has intersected thick intervals of copper mineralisation very close to surface, including exceptional high-grade zones with individual assays up to 27.3% Cu. We believe these intervals will enhance the development and expansion opportunity of Cyclone, highlighting the excellent continuity of the largest current open pit mine at Storm." – Dave O'Neill, Managing Director
Understanding Sediment-Hosted Stratiform Copper Deposits
Storm represents a sediment-hosted stratiform copper deposit, a geological formation that has produced some of the world's most significant copper mines. These deposits form when copper-rich fluids migrate through permeable sedimentary rocks and precipitate metals in favourable structural and chemical environments.
What Makes These Deposits Attractive?
Key characteristics that make these deposits attractive:
- Predictable geology with continuous mineralised horizons
- Large tonnage potential across extensive strike lengths
- Near-surface mineralisation reducing development costs
- High-grade zones within broader mineralised envelopes
Storm's mineralisation is hosted within the Allen Bay Formation dolostones, with chalcocite as the primary copper mineral. This geological setting provides excellent grade continuity and expansion potential, as demonstrated by the latest drilling results extending mineralisation beyond current resource boundaries.
Consequently, sediment-hosted deposits typically offer lower discovery costs, predictable metallurgy, and the potential for long-life mining operations with consistent production profiles. This geological advantage significantly enhances the investment proposition for American West Metals shareholders.
Reverse Circulation Programme Confirms Resource Expansion Potential
Beyond the spectacular diamond drilling results, American West's Reverse Circulation (RC) drilling programme continues to validate resource upgrade opportunities across multiple deposits. The programme has achieved 100% success rate intersecting copper mineralisation, with results supporting both resource expansion and grade improvements.
Key RC Drilling Highlights
| Hole ID | Prospect | Interval (m) | Cu (%) | Ag (g/t) | Significance |
|---|---|---|---|---|---|
| SR25-016 | Cyclone | 6.1 | 1.0 | 8.8 | Resource upgrade zone |
| SR25-017 | Cyclone | 9.1 | 0.6 | 3.7 | Extension drilling |
| SR25-019 | Cirrus | 4.6 | 0.7 | 2.3 | Deposit expansion |
| SR25-020 | Thunder | 3.0 | 2.7 | 3.0 | New target validation |
Upcoming catalysts for the drilling programme:
- Remaining assay results expected within 1-2 weeks
- Updated Mineral Resource Estimate incorporating all 2025 drilling
- Pre-Feasibility Study activities accelerating across multiple workstreams
In addition, these results continue to demonstrate the exceptional 27.3% copper grades at American West Metals' Storm Project, reinforcing the company's position as a premier North American copper developer.
Investment Thesis: Critical Minerals Leadership in Tier-1 Jurisdiction
American West Metals has positioned itself at the intersection of two major investment themes: North American critical minerals security and high-grade copper development. The Storm Project offers several compelling investment advantages in today's market environment.
Resource Scale and Grade Profile
With a current 228,500 tonnes of contained copper across 20.6 million tonnes at 1.11% Cu, Storm already ranks among significant North American copper developments. The ongoing drilling continues to demonstrate expansion potential, with results like the recent drilling programme highlighting exceptional grade zones within the broader resource.
Strategic Location Benefits
Located in Nunavut, Canada, Storm benefits from:
- Stable mining jurisdiction with established regulatory framework
- Growing government support for critical minerals development
- Proximity to established northern supply chains and infrastructure
- Strong indigenous community relationships
Furthermore, the project's near-surface mineralisation and proven metallurgy position Storm for potential rapid development. Recent ore sorting test work achieved 53.1% Cu concentrate from initial 6.52% Cu feed, demonstrating strong beneficiation potential that could reduce processing costs and environmental footprint.
Market Positioning
American West's meeting with the Governor of Utah scheduled this week underscores growing government engagement with domestic copper supply chain development. This high-level political support reflects the strategic importance of projects like Storm in North America's critical minerals security strategy.
Why Should Investors Follow American West Metals?
American West Metals has assembled a compelling combination of high-grade resources, strategic location, and development momentum that positions the company as a potential major player in North American copper production. The latest drilling results reinforce several key investment themes driving long-term value creation.
Near-Term Value Catalysts
- Updated resource estimate incorporating significant drilling expansion
- Pre-feasibility study advancing toward completion in 2025
- Government engagement accelerating at state and federal levels
- Metallurgical optimisation demonstrating improved processing economics
Long-Term Growth Potential
The Storm Project's 4.3km strike length with multiple deposits offers substantial exploration upside beyond current resources. Regional targets including Thunder, Lightning Ridge, and The Gap provide pipeline opportunities for resource expansion and new discoveries.
However, the most compelling aspect remains the consistent delivery of exceptional results, including the remarkable 27.3% copper grades at American West Metals that continue to validate the world-class nature of this copper system.
