American West Metals Limited (ASX: AW1 | OTCQB: AWMLF) has provided an update on its diamond drilling activities at the Storm Copper project, Nunavut.
Diamond drill hole ST23-03 has discovered a new near-surface zone of mineralization and a deeper sediment-hosted copper system in an underexplored area of the Storm project. The new near-surface copper has been named “Thunder”.
Hole ST23-03 has intersected two zones of visual copper sulphide mineralization. Highlights include:
- 76m of visual strong breccia to massive copper sulphide (chalcocite, bornite, and chalcopyrite) between 32m and 108m downhole
- 2m of visual breccia and dense vein style copper sulphide (chalcocite, bornite, and chalcopyrite) between 273m and 275m downhole
Managing director, Dave O’Neill, commented, “The diamond drilling at Storm continues to deliver, producing one of the best intersections ever seen at the project. Over 76m of near surface breccia copper sulphides with zones of massive sulphide have been intersected in the third diamond drill hole, ST23-03.”
Additionally, the company has stated that the deeper intersection is interpreted to correlate with the prospective sediment hosted copper horizon intersected earlier this year, and is the first recorded occurrence south of the Southern Graben Fault.
Laboratory assays are required to determine the presence and grade of any contained mineralization within the reported visual intersections of copper sulphides. Portable XRF is used as an aid in the determination of mineral type and abundance during the geological logging process.
American West are continuing diamond drilling to test key geophysical copper targets in the Storm area.
Also, the reserve circulation (RC) drilling is continuing in the Storm area with the results from the 2750N and 2200N Zones expected shortly. Drilling will also focus on expansion of the 4100N Zone and testing a number of new, near-surface copper targets.
An environmental baseline survey will continue in August 2023.
Mr. O’Neill continued, “The thickness of the near-surface intersection – which includes massive copper sulphides – suggests the potential for a substantial volume of copper in this area that could significantly add to the open pit resources at Storm.”
“The deeper copper intersection is very significant from the perspective of understanding the overall copper endowment at Storm. This confirms the prospectivity of the whole area around, and to the south of the southern graben fault. With every wide-spaced hole encountering the same mineralized unit at depth, the scale potential of the copper system cannot be overstated.”
