Adyton Confirms Significant Scale at Feni Gold-Copper Project: FDD005

Returns 158m @ 0.72g/t Au.Eq (0.54g/t Au & 0.14% Cu) and Identifies

New High-Priority Drill Targets.

Brisbane, Australia – October 14, 2025 – Adyton Resources Corporation (TSX Venture: ADY) (“Adyton”

or the “ Company”) 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 (Au.Eq) (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.

1 Interval widths are “apparent” widths downhole, subject to true width determination.

2 ADK series drilling (2021) reported previously to TSX.V. Au.eq recalculated here.

3 Gold equivalent calculated as: Au.eq = ((Au g/t *0.93) + (Cu% *1.71 * 0.90)). Based on: metal prices of US$2,000/oz Au

and US$5/lb Cu; and recoveries of 93% Au and 90% Cu. Recovery assumptions are speculative as no metallurgical test

work have been completed at Feni but are based on comparable deposits.

Quality Assurance / Quality Control

Adyton adheres to industry-recognized standards of Best Practice and Quality Assurance/Quality Control

(QA/QC). 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.
