Adyton Reports Final Assays from FDD004 Confirming Strong Mineralized Intercepts
of 115m at 1.00g/t Gold Equivalent (0.92g/t Au & 0.07% Cu) Within A Broader
Mineralized Zone of 229m at 0.79g/t Gold Equivalent (0.71g/t Au & 0.07% Cu), With
the Hole Ending in Gold-Copper Mineralization of 70.2m at 0.21% Cu & 0.33g/t Au
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.
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: 70.2m 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, commented:
“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.”

FDD004 has been drilled on the edge of the “gap zone”. Figures 1 and 2 highlights that the gold and
copper assay results from this drillhole show a number of important outcomes, namely:
1. 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’;
2. The copper assays will likely be a material addition to any future MRE (not previously in MRE);
3. The deeper copper-gold zone is below the base of the MRE and will likely add depth extent to any
future MRE.
Figure 2 : Cross section of FDD004. Of note, the drilling assays are materially higher than the historical
block model, including gold-rich zone near surface, and copper-rich zone at depth. Also noting from Figure
1, the block model does not expand to the east from here.

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 (1050C), 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.
