American West Metals Limited reported exciting exploration results at its Storm Copper Project in Canada. Drilling has revealed extensive copper gossans and high-grade sulphide intersections along an 8km strike, suggesting significant resource potential. Upcoming assays will provide further insights into this promising copper discovery.

American West Metals Limited has reported a significant breakthrough at its Storm Copper Project in Canada, where extensive copper gossan outcrops have been identified along an 8‐kilometer strike in the Tornado area. The company’s integrated exploration program—utilizing state‐of‐the‐art mobile magnetotellurics (MMT), detailed mapping and soil sampling, and both diamond and reverse-circulation (RC) drilling—has confirmed the presence of high-grade copper sulphides. Early field results have mapped extensive chalcocite and malachite mineralisation along a major fault network and provided visual evidence of thick, semi-massive sulphide intervals in two key geotechnical drill holes, PFS-001 and PFS-002, drilled on the margins of the Cyclone Deposit. Both drill holes recorded multiple intervals of copper-bearing minerals with promising widths, while a total of eight diamond drill holes (covering 1,786 meters) and 21 RC drill holes (spanning 3,194 meters) have been completed to upgrade the current resource estimate and expand high-priority exploration targets. Regional sampling and airborne geophysical surveys, including MMT imagery along the Midway-Storm-Tornado corridor, have bolstered confidence in the prospectivity of the area. Visual copper estimates, confirmed by portable XRF testing, indicate that these targets could host a large copper deposit at depth, although laboratory assays for precise grading are expected in the coming six to eight weeks. The announcement further details that the drilling orientation—optimized to achieve true-width intercepts through stratabound mineralisation—has revealed unexpected mineralisation at resource margins, suggesting further potential to increase the deposit’s size and quality. In addition to the encouraging drilling results, the company is advancing its pre-feasibility study (PFS) work along with continued environmental monitoring and further exploration phases. Detailed technical information—including drill hole coordinates, depths, geological logs, and metallurgical testing plans—has been provided to outline the progression toward a robust JORC-compliant Mineral Resource Estimate. The integration of historical exploration data with recent drilling campaigns underscores the careful approach and technical rigor that has driven this phase of the project. From an investor sentiment perspective, bullish notes stem from the considerable strike length of copper mineralisation, the high-grade visual intervals encountered, and the potential for resource expansion beyond current open-pit designs. The combination of promising geophysical anomalies and extensive field sampling adds weight to the prospect of a significant deposit contributing to a robust resource base. On the other hand, caution is warranted as final copper grades and economic viability remain subject to pending assay results and further metallurgical studies. Additionally, the forward-looking statements acknowledge standard exploration risks such as commodity price fluctuations, regulatory uncertainties, and the challenges inherent in mining projects within remote, Arctic regions. Overall, the announcement reflects a strong technical update with encouraging early results that could pave the way for further de-risking and potential resource growth at the Storm Copper Project while reminding investors that final confirmation of grades will be essential as the project progresses.
