American West Metals Limited (American West Metals or the Company) (ASX: AW1) is pleased to announce outstanding first assay results for the diamond drilling program by the Company at the Storm Copper Project (Storm or the Project) on Somerset Island, Nunavut, Canada.
- Drill hole ST22-05 from the 2750N Zone has intersected:
- 41m @ 4.18% Cu from 38m downhole, including;
- 15m @ 10.05% Cu from 47m downhole, and including;
- 5m @ 24.28% Cu from 48m downhole
- Further assays for Storm are pending with more results expected in the coming days
Dave O’Neill, Managing Director of American West Metals commented:
“Assays for drill hole ST22-05 – the first assays to be received for drilling in the current program – have returned spectacular copper grades over very significant thicknesses.
“These results immediately validate the historical high-grade intersections within the 2750N Zone, and highlight the quality of the Storm mineral system. These kind of grades and thicknesses are exactly what we want to see as we work to define a shallow high-grade copper resource.
“The 2750N Zone is currently over 200m long and still open along strike and at depth, with excellent potential for further drilling to significantly expand the high-grade mineralisation.
“Further results for this year’s drilling are imminent and we look forward to reporting these soon.”

DRILL HOLE ST22-05 DETAILS
ST22-05 was drilled to a downhole depth of 89m and is one of eight drill holes completed to date in the 2022 drill program that were designed to determine the resource potential of the shallow 2750N Zone (Figure 2).
The drill hole is located on the same section as drill hole ST22-04 (assays yet to be received) and was testing the upper continuation of the deeper mineralisation intersected in ST22-04 (Figure 3).
ST22-05 intersected a broad, 60m zone of vein and fracture style copper sulphide mineralisation from approximately 22m downhole. The stronger and more significant mineralisation within this interval consists of breccia and massive sulphides between approximately 38m and 79m downhole that yielded 41m @ 4.18% copper. A thick zone of massive bornite and chalcopyrite is present between 48m and 53m, which returned an average grade of greater than 24% copper.
Table 1 summarises the significant intersections from ST22-05. Intersections are expressed as downhole widths and are interpreted to be approximately 90% of true width. A cut-off grade of 0.5% copper is used to define a significant intersection and is based on ore mineralogy, mineralisation habit and expected beneficiation performance.
