Aston Bay and American West Metals Announce New Copper Intersections at the Storm Project, Nunavut, Canada

Executive Summary

• RC and deep diamond drilling at the Storm Copper Project intersected multiple high‑grade copper–silver intervals, including 12.2 m @ 1.9% Cu & 77 g/t Ag and a total of ~57 m of visual copper mineralization in hole ST25‑04.
• The results support strong resource upgrade potential and indicate the possibility of expanding the pit‑constrained resource beyond current conceptual pit walls.
• A second deep diamond drill hole (ST25‑04) reached 692 m, intersecting two broad zones of visual copper sulphide mineralization and identifying a new organic‑rich horizon that may host additional base‑metal targets.

Key Details

• RC Drilling Highlights (first 10 holes):
• SR25‑005 (Corona): 12.2 m @ 1.9% Cu, 77 g/t Ag (19.8–32.0 m).
• SR25‑005: 4.6 m @ 3.2% Cu, 129 g/t Ag (27.4–31.9 m).
• SR25‑005: 1.5 m @ 2.9% Cu, 115 g/t Ag (30.5–32.0 m).
• SR25‑006 (Corona): 7.6 m @ 1.7% Cu, 3.2 g/t Ag (25.9–33.5 m) with sub‑intervals of higher grade.
• SR25‑007 (Corona): 4.6 m @ 1.1% Cu, 1.3 g/t Ag (25.9–30.5 m).

• SR25‑010 (The Gap): 7.6 m @ 1.1% Cu, 2.2 g/t Ag (73.2–80.8 m); assays pending below 128 m.

• Diamond Drilling – Hole ST25‑04:

• Total depth: 692 m; intersected two visual copper sulphide zones: 183–215 m and 298.5–327 m.
• Upper zone: crackle breccia with sulphide matrix, localized high‑grade pockets at 183‑184 m & 196‑197 m.
• Lower zone: organic breccia containing native Cu, malachite, bitumen (298.5‑327 m).
• Additional pyrite mineralization encountered near the South Graben fault (578‑593 m).

• Presence of organic‑rich shale/dolostone (578‑635 m) suggests a new base‑metal trap horizon.

• Overall Drill Program (2025):

• Total of 9 diamond holes completed (2,295 m) including the deep Cirrus target.
• RC program covered Corona, Thunder, Lightning Ridge deposits and The Gap prospect; all aimed at resource upgrade and expansion.

• Table of significant intersections (cut‑off 0.3% Cu) shows multiple >5 m intervals above 1% Cu across several prospects.

• Joint Venture Structure:

• Aston Bay holds a 20% free‑carried interest in the Storm Project JV with American West Metals (80%).

• Carried interest remains until a bankable feasibility study triggers a mining decision; thereafter, Aston Bay may convert to a 2% NSR royalty if diluted below 10%.

• Qualified Person: Michael Dufresne, P.Geo., reviewed and approved the technical information.

Notable Quotes

“We are excited to report these new intercepts of near‑surface copper mineralization… Many of these new intersections are located outside the conceptual pit walls and demonstrate excellent potential to expand the mineral resource.” – Thomas Ullrich, CEO, Aston Bay Holdings

Materiality Assessment: Material – Positive (the high‑grade intersected intervals materially enhance the outlook for a resource upgrade and future development potential).
