American West Metals confirms new copper system at the Storm Project

Initial assay results from American West Metals’ drilling at the Storm Copper Project on Somerset Island, Nunavut, Canada have confirmed a significant discovery, the Company says.
Drill hole ST22-10 highlighted sediment hosted copper and zinc sulphide mineralisation below the near-surface high-grade deposits at the project.
Notably, the discovery drill hole is associated with a series of untested large and coincident geophysical anomalies identified across a zone that extends for more than 5km, indicating the potential for a large-scale sedimentary copper system at depth.
American West Metals (ASX:AW1) MD Dave O’Neill said the results have huge implications for the potential metal endowment of the project – which has previously returned intersections including 110m at 2.45% Cu from surface and 6.84m at 8.98% Cu from surface.
The company says the results validate its geological model that interprets the extensive near-surface high-grade copper mineralisation at Storm to be associated with a much larger sedimentary copper deposit at depth.
“These results demonstrate that in addition to the near-surface high-grade copper deposits, we have a second type of copper deposit at Storm,” O’Neill said.
“This sedimentary copper mineralisation style is typically associated with very large deposits, such as the large-scale copper deposits in the Congo and the Kupferschiefer deposits in Central Europe.
“The discovery drill hole at Storm is associated with a series of large IP, EM and gravity anomalies that sit below or adjacent to the known high-grade copper prospects and major faults.
“These features occur across a zone more than 5,000m long, supporting the potential for a very large sedimentary copper system.”
Further assays from the Storm drill program are due soon, with beneficiation text work to commence shortly, focusing on further optimising the process to produce a direct shipping ore (DSO) product.
Plus, further diamond drilling and surface electromagnetics are planned to follow-up the new deeper discovery as well as the shallow mineralisation at the 2750N Zone.
“This is a tremendous exploration opportunity, and we are already planning follow-up exploration and drilling,” O’Neill said.
