Aston Bay and American West Metals Announce 13% Copper in Assays at the Cyclone Deposit and a New Copper Discovery at the Storm Project, Nunavut, Canada

Drilling Highlights

• Drilling surpasses 20,000 metres (“m”) with 128 Reverse Circulation (RC) drill holes and 14 diamond drill holes now completed in 2024 at Storm and Tempest
• Drilling continues 24/7
• The resource potential of the Cyclone Deposit is further highlighted with exceptional high-grade copper intervals confirmed by assays including:

• Drill hole SR24-057 has intersected:
  • 1.5m @ 13.5% copper (“Cu”), 23g/t silver (“Ag”) from 54.9m downhole, and,
  • 3.1m @ 2.0% Cu, 8.0 g/t Ag from 85.3m downhole, and,
  • 1.5m @ 1.8% Cu, 3.0g/t Ag from 109.7m downhole
• Drill hole SR24-035 has intersected:
  • 3.1m @ 3.9% Cu, 10.5g/t Ag from 57.9m downhole, including,
    • 1.5m @ 5.9% Cu, 16.0g/t Ag from 57.9m downhole, and,

• 4.6m @ 1.4% Cu, 5.0g/t Ag from 71.6m downhole, including,
  • • • • • 1.5m @ 3.1% Cu, 11.0g/t Ag from 71.6m downhole

• Drill hole SR24-031, located outside of the known zone of mineralization, has intersected:
  • 27.4m @ 1.1% Cu, 3.5g/t Ag from 96m downhole, including,
    • 4.6m @ 3.1% Cu, 7.7g/t Ag from 109.7m downhole

Exploration drilling and Moving Loop Electromagnetics (MLEM)

• Drilling of an MLEM anomaly in an untested area south of the Thunder Prospect has intersected strong visual copper sulfides from approximately 181.4m downhole – this new discovery is named ‘Squall’
• The deep-searching 400m loop MLEM survey is currently underway at Tornado where it has identified two EM anomalies spatially coincident with outcropping copper
• Drilling of the 1,300m x 500m EM anomaly below the Cirrus Deposit is in progress with the diamond hole planned to a depth of 600m
