Adyton Resources Corporation (TSX-V: ADY) is pleased to report final assays from expansionary drill hole FDD005 at its 100% owned Feni Au-Cu project, Papua New Guinea. The results continue to confirm the significant scale of the Feni gold-copper mineral system, whilst also highlighting the challenges and opportunities of exploring a very large mineralized system that is under cover, particularly to target and intercept higher-grade gold-copper zones.

HIGHLIGHTS

• 158m @ 0.72g/t gold equivalent (0.54g/t Au & 0.14% Cu), including 32m @ 1.09g/t Au.Eq (0.99g/t Au & 0.11% Cu) from drill hole FDD005

• FDD005 is the fifth consecutive drill hole with assays >100gxm Au.Eq

• Furthermore, FDD005 ended with significant molybdenum at end of hole (383ppm Mo) signifying a direct link to a deeper-seated intrusive-related mineral system

• FDD004 and FDD005 encountered strong and broad zones of gold and copper mineralization within the “gap” zone that is wide open for expansion between the two open pit MRE resources

• FDD005 provides key geological and structural insights into the Kabang area, including new understanding of the relationship between sulphide content and gold/copper grade, which is critical for future targeting

• Geophysics and assay re-interpretation identifies multiple additional high-priority targets within the Kabang prospect, potentially unlocking significant upside.

Tim Crossley, Chief Executive Officer, commented:

“The drilling of hole FDD005 was a bold move in the middle of the “gap” area in our block model. It is the deepest hole ever drilled at Feni with a gold bearing vertical footprint of greater than 700m. Our next focus is to integrate the new data from our current drill program into our historical data set and recent close-spaced drone magnetic survey to vector in on and identify the higher-grade zones within this extensive mineral system.”

Dr Chris Bowden, Chief Operating Officer and Chief Geologist, commented:

“While the highlight intersection in FDD005 was lower-grade than previous drillholes, it still reported >100gxm and the two very broad zones of gold-copper mineralization (382m @ 0.43g/t AuEq (from 69m) and 332m @ 0.13g/t AuEq (from 508m to EOH)) clearly indicate the footprint and scale of the system at Feni is extensive. Subsequently, we have re-interrogated the assay results with the outcomes from geophysics data (including high resolution drone survey). We now have higher confidence that FDD005 likely sits in a structural offset, explaining the significantly wide and highly anomalous grades. Furthermore, the re-review of the geophysics and assay results has resulted in a revised understanding of the potential structural controls to mineralization (more akin to the structural setting at Lihir).”

Discussion of Results

Whilst it is very early days, the dynamic and ongoing process of re-reviewing the geophysics with new assay results as received allows us to refine our geological model. This process has directly resulted in a number of additional targets now highlighted as more prospective than previously considered, and if successful, would likely result in significant upside to potential targets at Kabang. Adyton is prioritizing the newly identified geophysical targets in our current phase of drilling (4Q2025) and expects this revised geological model to significantly enhance our exploration success rate.

Table 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.

Quality Assurance / Quality Control

Adyton adheres to industry-recognized standards of Best Practice and Quality Assurance/Quality Control. Drill core samples were submitted in batches to Intertek Laboratory in Lae, which include a field blank, certified reference materials (CRMs) and staged duplicates. Samples were sealed using single-use tie-locks ensuring Chain of Custody. To date, all batches have passed QA/QC, and blanks and CRMs were within acceptable tolerance limits. All drill holes were drilled and sampled predominantly from PQ and/or HQ diameter drill core, and to a much lesser extent, also NQ core. Core recovery is considered to be appropriate.

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 Bismark Islands in PNG. Feni Island is part of the 250km long Tabar-Lihir-Tanga-Feni 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.

ABOUT ADYTON RESOURCES CORPORATION
