Extensive geophysics program commences at Hennes Bay copper-silver project, building on successful 2025 program

Full announcement

This press release is a summary of the Full Announcement which is enclosed to this press release and can also be accessed via this link.

Highlights

• 2026 Geophysics Program commenced at Hennes Bay
• Extensive airborne Magneto-Telluric ("MMT") survey underway
  • Initial MMT survey in 2025, which covered only ~34% of the overall 414km² tenement package, successfully identified several new target areas with a combined area 10 times larger than the footprint of the existing 55Mt @ 1.0% CuEq Mineral Resource Estimate ("MRE") at Dingelvik
  • 2026 MMT survey covers an additional 150km² immediately to the north and south of the initial survey, including part of the MRE and strike extensions of the prospective copper horizon
• Ground gravity survey of Dingelvik and surrounding areas being undertaken to investigate large scale tectonic thrusting structures potentially concealing mineralised strata at depth beneath granites
• Geophysical surveys provide an efficient and cost-effective means to evaluate the Project's immense resource growth and exploration upside potential
• Results from the MMT and gravity surveys are anticipated in the current quarter and will further inform target generation and drill prioritisation for current and future drilling programs

Arctic Minerals' Managing Director and CEO Peter George commented:

"After the success of the initial MMT survey in 2025, it makes sense to continue to push the boundaries of our understanding of potential target areas at our flagship Hennes Bay copper-silver project. We strongly believe that Hennes Bay hosts a large-scale sediment-hosted copper mineral system and these modern geophysical techniques provide us a quick and effective means to evaluate the aerially extensive target horizon within the 414km² tenement package. The resultant high confidence targeting allows us to focus our drilling to ensure we maximise use of shareholder funds and add value to the Company. I am looking forward to presenting the results of the MMT and gravity surveys as well as the ongoing phase 1 drilling program in the coming months."
