American West Metals Limited (American West Metals or the Company) (ASX: AW1) is pleased to announce further outstanding 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 ST22-02 has intersected:
- 57m @ 2.5% Cu from 8m downhole, including;
- 1m @ 21.9% Cu from 14m downhole, and;
- 8m @ 7.86% Cu from 29m downhole, including;
- 3m @ 12.12% Cu from 34m downhole, and;
- 2m @ 10.24% Cu from 48m downhole
- 57m @ 2.5% Cu from 8m downhole, including;
- Result further confirms continuity of the near surface high-grade copper at the 2750N Zone
- Further assays for Storm are pending with more results expected in the coming weeks
Dave O’Neill, Managing Director of American West Metals commented:
“Assays continue to return spectacular copper intersections at the 2750N Zone.
“ST22-02 has intersected thick, high-grade copper just 8m from surface again highlighting the quality and shallow nature of copper sulphide mineralisation at the 2750N Zone.
“Results from the 2750N Zone are quickly confirming the potential for a high-grade open pit and DSO mining operation with outstanding expansion opportunities.
“We are also eagerly awaiting the results for drill hole ST22-10, which has intersected a thick sequence of sedimentary copper mineralisation below the shallow high-grade zones. We believe this new style of copper deposit at Storm is a game changing discovery, which may have huge implications for the copper endowment in the region.
“This year’s drilling program is exceeding our expectations, and we are clearly defining two exciting growth stories within the Storm Project.
“Further results are expected soon and we look forward to reporting on these in the coming weeks.”

DRILL HOLE ST22-02 DETAILS
ST22-02 was drilled to a downhole depth of 155m and was designed to test the continuity of the copper mineralisation in the central 2750N Zone (Figure 1).
The drill hole intersected a broad, 83m zone of vein and fracture style copper sulphide mineralisation from approximately 5m downhole. The volume of copper sulphide throughout the interval is variable and is controlled by the intensity of rock fracturing within the broader fault zone.
The stronger mineralisation in ST22-02 (and throughout the 2750N Zone) consists of massive and semi-massive chalcocite and/or bornite and is hosted within large fractures and breccia zones. The stronger zones within ST22- 02 occur between 14m and 15m (21.9% Cu), 29m and 37m (7.86% Cu), 48m and 50m (10.24% Cu), 53m and 56m (3.07% Cu), 82m and 83m (3.93% Cu) and 87m and 88m (4.97% Cu) downhole (Table 1 & Figure 2).
The remaining half-core from ST22-02 will be used for beneficiation and metallurgical test work to produce a direct shipping ore (DSO) product from the 2750N Zone mineralisation.
Table 1 summarises the significant intersections from ST22-02. 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.
