December 2025 Quarterly Activities Report - New target area 10 times the footprint of maiden resource at Hennes Bay which totals 447,000t of contained copper and 37Moz of silver

Highlights during and subsequent to quarter end:

• Flagship Hennes Bay Copper-Silver Project
  • Exploration works demonstrated a significant increase in target area.
    • Processing and interpretation of an airborne magnetotelluric ("MMT") survey and magnetic vector inversion ("MVI") modelling of historical airborne magnetic data was completed.
    • Integration of the geophysical datasets resulted in the identification of several new target areas, including extensions of known prospects and new anomalies both near surface and at depth. Significantly, the MMT survey covered only ~34% of the overall 402km² tenement package.
    • The combined area of new targets is 10 times larger (based on areal extrapolation) than the footprint of the existing 55Mt @ 1.0% CuEq (0.8% Cu & 20.8g/t Ag) Mineral Resource Estimate ("MRE") at Dingelvik.
    • The next step includes field verification, followed by target ranking and prioritisation for drill testing. Additional MMT surveys are also planned for 2026.
  • Positive Underground Conceptual Mining Study confirmed the technical feasibility of large-scale UG Room and Pillar mining, based solely on the existing MRE.
• Swan Lake Copper-Gold Project
  • Located within the Proterozoic Norrbotten volcanic belt between the giant Aitik and Laver porphyry copper-gold ("PCG") deposits, the project is characterized by a large-scale alteration system spanning tens of km².
  • Previous exploration work has identified magnetic high and low anomalies associated with copper and gold mineralized quartz vein systems, with surface outcrop sampling results up to 0.7% Cu, 0.16g/t Au and 55g/t Ag.
  • Additional geological mapping and sampling, and gradient array and dipole-dipole induced polarisation ("IP") geophysical surveys have been recently completed.
  • Results from the IP surveys are expected within the next month.
