Brisbane, Australia – September 8, 2025 – Adyton Resources Corporation (TSX Venture: ADY) ("Adyton" or the "Company") is pleased to report final assays from drillhole FDD004 at its 100% owned Feni Island gold-copper (Au-Cu) project, located within the gold-prolific Lihir Island Chain, Papua New Guinea (PNG). The results confirm long >200m intercepts of consistent gold mineralization.
Highlights
- FDD004 represents another drillhole returning significant and continuous gold-copper intercepts from the Feni Island project, consistent with assay results from FDD001, FDD002 & FDD003;
- FDD004 returned 115m at 1.00g/t Gold Equivalent (Au.Eq) (0.92g/t Au & 0.07% Cu), within a broader interval of 229m at 0.72g/t Au.Eq (0.71g/t Au & 0.07% Cu);
- FDD004 also ended in gold and copper mineralization: 2m at 0.21% Cu & 0.33g/t Au (0.57g/t Au.Eq);
- FDD004 successfully encountered strong gold and copper mineralization within a targeted "gap" in the current block model which currently has minimal blocks above cut-off reporting to the existing MRE.
Tim Crossley, Chief Executive Officer, stated:
"The results from FDD004 continue to demonstrate the scale of the mineral system with in excess of 200m of continuous mineralization and the hole bottoming in copper and gold mineralization. Hole FDD004 was also an important hole having been drilled in a gap area within the block model. With holes 5, 6, and 7 now sampled and dispatched to the lab, we can expect ongoing results in the coming weeks and months; given the current observed consistency in grades in the upper hydrothermal breccia zone, we are confident that where the hydrothermal breccia's repeat in these holes, we anticipate ongoing strong grades in these mineral zones."
Dr Chris Bowden, Chief Operating Officer and Chief Geologist, commented:
"It is rare to work on an early-stage exploration project and continue to hit significant gold-copper intersections. This is a testament to the geological robustness of the Feni Project, and the regional prospectivity of the gold-prolific Lihir Island Chain. Looking forward, in knowing the post-mineral tephra cover has a large footprint (effectively hiding the mineralization at surface), we need to leverage our observations on geology, mineralization, alteration zonation, structural controls, and paragenesis. By better understanding these controlling factors to mineralization, we can continue to optimize the drill program and optimize the probability of success."
Significant Intercepts and Geology
Significant Intercepts for gold and copper assay results have been received to date for the first four drill holes in 2025.
Notes: Interval widths are "apparent" widths downhole, subject to true width determination. Gold equivalent calculated as: Au.eq = (Au g/t + (1.12 × Cu %)). Assuming 100% recovery – detailed met pending. FDD002 & FDD004 ended in mineralisation.
FDD004 has been drilled on the edge of the "gap zone". The gold and copper assay results from this drillhole show a number of important outcomes, namely:
- The upper gold-rich (plus copper) hydrothermal breccia is reporting grades higher than previously modeled. This will increase the grade and confidence in this location and will likely expand the MRE in proximity to this drillhole, namely to the east 'filling the gap';
- The copper assays will likely be a material addition to any future MRE (not previously in MRE);
- The deeper copper-gold zone is below the base of the MRE and will likely add depth extent to any future MRE.
Drillhole status notes: FDD008 was abandoned at a shallow depth while still in post-mineral cover due to operational issues, redrilled as FDD009. FDD002 was terminated prematurely due to ground conditions while still in observed visual mineralisation. WGS 84 Zone 56S UTM coordinates.
Feni Island Gold-Copper asset, on-trend location to giant gold +/- copper mines
The Adyton Feni Island Au-Cu project is strategically located on the easily accessible Outer Bismark Islands in PNG. Feni Island is part of the 250km long gold-prolific Lihir Island Chain, which to the northwest hosts the operating gold mines of Simberi and the giant Lihir mine, while Feni hosts a foundational resource of 1.45moz Au. To the southeast of Feni Island, on Bougainville Island, lies the giant past producing Panguna Cu-Au mine.
Sampling and Quality Assurance / Quality Control
Adyton adheres to industry-recognized standards of Best Practice and Quality Assurance/Quality Control (QA/QC). All drill holes were drilled and half core sampled predominantly from PQ and HQ diameter drill core with lesser amounts of NQ core sampling. Samples undergo an auditable record from point of drilling (including sealed using single-use tie-locks) to delivery to the laboratory, ensuring chain of custody. Drill core samples were submitted in batches to Intertek Laboratory in Lae, Papua New Guinea, an ISO 9001 certified laboratory. Samples are dried (105°C), crushed (95% <3mm), and pulverised (95% <75µm). Analytical testing includes 50gm fire assay digest and AAS determination for gold, and a four-acid digest with ICP determination for a 33 multi-element suite. QA/QC samples were inserted into the batches in accordance with industry-standard practices, and include: a field coarse blank, certified reference materials (CRMs) and staged duplicates (coarse, crush and pulp). To date, all batches have passed QA/QC, and blanks and CRMs were within acceptable tolerance limits.
Adyton has no direct relationship with Intertek laboratory.
