Port Moresby, PNG – June 12, 2025 – Adyton Resources Corporation (TSX Venture: ADY) ("Adyton" or the "Company") is pleased to provide an update on its ongoing 2025 drilling activities and share preliminary geological observations at its 100% owned Feni Island project.
The 2025 drill program is designed to achieve 4 key objectives:
- Test the depth extension of the existing Feni Resource with deep 400m+ drill holes;
- Test the extent of mineralization in the gap area between the existing Kabang and Matangkaka Ore Zones;
- Test and better understand the continuity of the previously identified copper mineralization; and
- Test the lateral northeast extension of the Matangkaka Zone under post-mineral cover, that has had no previous drilling.
Highlights
- As at June 6, 2025, six diamond drill holes (1,876m) have been drilled with 4 drill holes completed and two in-progress.
- Sawn core samples from Holes 1, 2 and 3 have been dispatched to the laboratory and are awaiting results.
- Target hole depths are typically 400m, with FDD003 and FDD004 ending at 421.7m and 453.2m respectively. FDD004 was terminated largely due to operational reasons with end-of-hole observations indicating ongoing vein-hosted and disseminated sulphide mineralization.
- Core logging observations indicate mineralization from base of tephra (post-mineral volcanic cover; ranging from 38m to 70m), with local intercepts of semi-massive (20%–30% pyrite), along with significant lengths of disseminated, vein and fracture-filled pyrite-chalcopyrite mineralization in hydrothermal breccia, polymictic breccia and intrusive units.
- FDD004 targets the untested gap between Kabang and Matangkaka. Anhydrite-pyrite-chalcopyrite (est. 1%) ± minor bornite vein-related mineralization was logged from 383.9m to 453m (EOH). A porphyry-style alteration assemblage of secondary biotite-magnetite-actinolite-chalcopyrite was logged from 383.9m to 424m with stockwork pyrite-chalcopyrite-magnetite veining from 383.9m to 397.5m and 402.3m to 424m.
- FDD005 intersected semi-massive sulphides (20–30% pyrite + chalcopyrite) from 89.7m to 96.0m and intermittent semi-massive pyritic sulphide intervals from 120.0m to 156.5m. Intense anhydrite veining associated with fine-grained pyrite + 0.5–1% chalcopyrite mineralization from 156.5m to 255.1m. From 255.1m to 340.0m, weak potassic alteration is associated with ~1% disseminated chalcopyrite.
- FDD001 intersected pyrite-mineralized hydrothermal breccia from 75.8m to 151.50m; 151.5m to 168.6m is intensely fractured within hydrothermal breccia with fine-grained pyritic sulphides filling the breccia matrix. From 168.6m to 396.0m, logged units include intermittent hydrothermal breccia, intrusive units and tephra with disseminated and vein-filled pyritic sulphides.
- FDD002 intersected mineralized hydrothermal breccia from 45.9m to 125.0m. The interval 125.0m to 195.4m is intensely fractured with disseminated and fracture/vein filled fine-grained sulphides (pyrite). FDD002 was terminated in mineralization (at 195.4m) due to operational issues.
- FDD003 intersected sulphide (pyrite) mineralized hydrothermal breccia from 57.0m to 110.0m. Intensely fractured intrusive with intermittent semi-massive, disseminated, fracture/veinlet filled pyrite-chalcopyrite (up to ~1%) mineralization was encountered from 110.0m to 186.5m, 197.0m to 218.1m and 227.0m to 277.7m.
Cautionary Statement: Observations of mineralization do not necessarily accurately predict true laboratory determined assay mineralization. Analytical assay results are pending and required to confirm the presence and grade of mineralization.
Tim Crossley, Chief Executive Officer, stated:
"Significant progress is being made at the 100% owned Feni Island project, with our drill programme now having completed 4 drill holes, with holes 5 and 6 underway, and over 1800m completed. Holes FDD001 and FDD002 were drilled in a geothermal area with challenging drilling conditions, characterized by intense alteration, hot springs, and highly fractured and altered ground. Despite these difficulties, the team performed exceptionally well, still achieving excellent core recoveries. We are encouraged by the visual logging results of the holes, particularly Hole 4 and the ongoing Hole 5. With the extent of drilling underway across all our projects, including on Fergusson Island, we are well-positioned to provide the market with regular updates as assay results become available in the coming months."
Dr Chris Bowden, COO and Chief Geologist, commented:
"We are encouraged by what we are seeing in the drill core from this round of drilling at Feni. Whilst assay results are still pending, visual observations are showing long intercepts >100m of hydrothermal to intrusive breccias that are evidencing mineralisation with sulphides (pyrite ± chalcopyrite) and intensely altered (sulphide ± silica-clay) – the sulphides being the typical host to the gold stage of mineralisation at Feni as evidenced from previous drill campaigns, correlation to historical assays and historical petrography."
Feni Island on-trend location
The Adyton projects are located in PNG on easily accessible island locations. Feni Island is part of the Tabar to Feni Island chain to the Northwest that hosts the operating gold mines of Simbiri and Lihir, while Feni hosts a foundation resource of inferred 1.45moz Au. To the southeast of Feni on Bougainville Island lies the giant Panguna deposit.
