Adyton Resources drills 24 m of 0.51% Cu at Feni Island

Executive Summary

• Adyton Resources Corp. released final assay results for the first three diamond drill holes (FDD001-003) at its Feni Island gold-copper project in Papua New Guinea.
• The results confirm multiple zones of copper mineralization that complement previously reported gold intercepts, with Hole FDD003 upgraded by 40% to a combined 125.9 gxm AuEq.
• All three drill holes reported significant intercepts exceeding 100 g-m on an AuEq basis, reinforcing the geological robustness of the asset and highlighting potential for future resource upgrades.

Key Details

• Hole FDD003 Copper Intercepts:
  • 24 metres at 0.51% copper (Cu)
  • 5 metres at 0.48% Cu
  • 12 metres at 0.23% Cu
• Hole FDD003 Gold Equivalent Upgrade:
  • The significant intercept grade increased to 1.36 g/t gold equivalent (AuEq) over 81 metres (109.8 gxm).
  • Combined significant intercepts for FDD003 now total 125.9 gxm AuEq, representing a 40% upgrade from the initial gold-only estimate of 90 gxm.
• General Drill Hole Performance:
  • Each of the three Feni Island drill holes now reports more than 100 g-m on an AuEq basis.
  • Copper assays show coherent zones >0.5% Cu within gold mineralized intervals (>1 g/t Au), suggesting strong potential for future mineral resource estimate (MRE) upgrades.
• Drilling Program Update:
  • Since the July 21, 2025 news release, an additional 1,064 metres of drilling have been completed.
• Project Context:
  • Feni Island is part of the Tabar-Lihir-Tanga-Feni Island chain, located near operating mines Simberi and Lihir, and the past-producing Panguna Cu-Au mine.
  • Current MRE (Oct 14, 2021) for Feni Island: 60.4 million tonnes at 0.75 g/t Au for 1.46 million oz Au (Inferred).
  • Current MRE (Oct 14, 2021) for Fergusson Island: 4.0 million tonnes at 1.33 g/t Au (Indicated) and 16.3 million tonnes at 1.02 g/t Au (Inferred).

Notable Quotes

• Tim Crossley, CEO: "We are very encouraged that the first three drill holes of this program are all reporting greater than 100 g-m AuEq basis. The addition of the copper assays reinforces our view that the Feni Au-Cu asset contains strong potential for significant copper mineralization, alongside the previously reported gold."
• Dr. Chris Bowden, COO and Chief Geologist: "To have the results from the first three drill holes from a new drill program all return more than 100 g-m AuEq highlights the geological robustness of the Feni project... This is only the beginning for Feni, and we look forward to keeping the market updated as future gold and copper assay results are received."
