Aston Bay and American West Metals Announce Large-scale Copper Potential Reaffirmed by New Drilling and Geophysics at the Storm Project, Nunavut, Canada

10 July 2025

Diamond drilling at Cyclone Deeps intersects sediment-hosted style copper mineralization at depth coincident with large MobileMT anomaly
 

Highlights:

  • Cyclone Deeps drilling success: diamond drill hole ST25-02 was drilled adjacent to and below the large near-surface Cyclone Deposit and has intersected approximately 47metres (“m”) combined total of visual sediment-hosted copper mineralization of similar style and mineralogy
     
  • Multiple new copper targets identified with geophysics. Phase 1 of the airborne Mobile MagnetoTellurics (MMT) survey has been completed along the Midway-Storm-Tornado corridor with encouraging preliminary results received, including;
    • The initial orientation survey has successfully detected the large, shallow, and flat-lying Cyclone Deposit, confirming the effectiveness of this geophysical technique to detect copper sulfide mineralization at the Storm Project
    • Five additional large and favourably located conductive features have also been identified between an interpreted 0m and 350m depth
    • A series of kilometre-scale conductive anomalies have been identified in the deeper-searching, low-frequency data interpreted to be >350m depth.
    • Approximately 1,320 line-km has been flown to date with detailed data processing, interpretation and 3D modelling in progress
       
  • Reverse-Circulation (RC) drilling progressing rapidly: 12 RC drill holes completed to date, including;
    • 7 holes completed at the Thunder, Lightning Ridge, and Corona Deposits for resource category upgrade purposes
    • 2 holes completed testing shallow resource extensions to the south of the Cyclone Deposit
    • 2 exploration holes completed at The Gap and southern graben areas
    • Logging is underway, and initial observations are expected in the next 1-2 weeks, with assays expected in the next 4-6 weeks
       
  • Government of Nunavut grants $250,000 to support the 2025 drilling
 Visual estimates of mineral abundance should never be considered a proxy or substitute for laboratory analyses where concentrations or grades are the factor of principal economic interest. Laboratory assays are required to determine the presence and grade of any contained mineralization within the reported visual intersections of copper sulfides. Portable XRF is used as an aid in the determination of mineral type and abundance during the geological logging process.

TORONTO, Ontario, July 10, 2025 – Aston Bay Holdings Ltd. (TSXV: BAY) (OTCQB: ATBHF) ("Aston Bay" or the "Company") is pleased to announce preliminary results from exploration activities at the Storm Copper Project ("Storm" or the "Project") on Somerset Island, Nunavut. American West Metals Limited ("American West"), the Project operator, is conducting the exploration program. Aston Bay and American West have formed a 20/80 unincorporated joint venture with respect to the Storm Project property, with Aston Bay maintaining a free carried interest until a decision to mine is made upon completion of a bankable feasibility study.
