Adyton 2025: Momentum, Execution

and a Clear Path Forward

Brisbane, Australia – December 22, 2025 – Adyton Resources Corporation (TSX Venture: ADY) (“Adyton” or the

“Company”) is pleased to announce a message from its Managing Director, Tim Crossley.

Tim Crossley, Managing Director

To the Stakeholders and Shareholders of Adyton Resources -

As we approach Christmas and the New Year, I would like to take the opportunity to reflect on the year that has been

and look forward to 2026.

2025 was a transformaƟonal year for Adyton during which we laid the foundaƟons for the Company’s next phase of

growth. Key strategic pillars were implemented, and the Company successfully advanced on the ground exploraƟon

acƟviƟes across both our 100% owned Feni Island Project and the Fergusson Island Projects, located in Papua New

Guinea (“PNG”).

Drilling at the Fergusson projects commenced in late 2024 and con Ɵnued through 2025 while drilling at Feni began

in March 2025, marking an important milestone for the Company. Across all projects, Adyton completed a total of

approximately 16,000 metres of drilling during the year, significantly advancing our understanding of these highly

prospecƟve gold, and in the case of Feni, gold and copper, systems.

Strategy ReflecƟon

In April 2024 the Adyton Board set a strategy to advance all of the Company’s projects concurrently, an ambi Ɵous

objecƟve for a junior explorer with limited funding at the Ɵme. We were, however well posi Ɵoned with several

advanced exploraƟon assets at Fergusson Island ready to enter the permi ƫng phase, alongside Feni Island, one of

the most compelling Tier 1 exploraƟon opportuniƟes in PNG.

The Board also reaffirmed its focus on Island based projects with excellent access and logisƟcs and idenƟfied an

opportunity at Fergusson Island with the clear objecƟve of bringing these assets into cash flow. Achieving this would

enable the ongoing advancement of Feni through internally generated funds while minimising shareholder diluƟon.

I am pleased to report that the execuƟon of this strategy has delivered the outcomes we set out to achieve. Our Joint

Venture partner EVIH, has made strong progress on advancing the Fergusson assets, providing the confidence to

establish a target date for the restart of the Wapolu Project in late 2026. This progress, combined with the Company’s

approximately 20-month cash runway, places Adyton in a very strong posi Ɵon to fully deliver on the intent and

outcomes of the Board’s 2024 strategy.

Feni Island Project

Adyton’s return to on the ground exploraƟon at Feni marked a major inflecƟon point for the Company in H2 2024,

beginning with an extensive field reconnaissance program and a first-ever whole of Island drone magneƟc survey.

This modern geophysical dataset has materially enhanced the Company’s understanding of the mineralized

architecture across Feni and conƟnues to directly inform drill targeƟng.

Building on this momentum, Adyton mobilized PNG based drilling contractor Zenex to site in late February 2025 with

drilling commencing in March. The ini Ɵal program focused on confirma Ɵon and infill drilling at the exis Ɵng Kabang

Resource, providing a strong technical foundaƟon for resource growth. With this work largely complete, drilling has

advanced into step out and expansion mode, targe Ɵng the margins of Kabang and tes Ɵng newly iden Ɵfied

geophysical anomalies that mirror the signatures of known high-grade zones beyond the current resource boundary.

Results to date within the Kabang system have exceeded expecta Ɵons and provide strong confidence that the

ongoing drill program could materially expand the Kabang Resource . Of par Ɵcular excitement are recent step-out

holes southwest of Kabang, where core observa Ɵons and strong near surface visual mineralisa Ɵon indicate the

potenƟal discovery of a previously unrecognized ore zone. This emerging zone highlights the broader scale potential

beyond the limits of the existing Kabang system and reinforces the opportunity for multiple centres of mineralisation

within the Feni project area.

The Company’s recent engagement of Global Ore Discovery and renowned epithermal and Lihir specialist Dr. Erin

Johns has further strengthened the technical team and sharpened the exploraƟon thesis. Their work has re-affirmed

that Feni hosts mul Ɵple Kabang -style epithermal targets alongside high-impact concealed porphyry targets,

posiƟoning th e project as a district- scale explora Ɵon opportunity with significant upside beyond the current

resource.

In parallel with explora Ɵon success, Adyton conƟnues to demonstrate leadership in local engagement and

sustainable development. More than 95% of our Feni workforce are PNG naƟonals with the majority recruited

directly from Feni Island. The Company also maintains a 100% PNG based logisƟcs and supply chain, ensuring the

benefits of exploraƟon acƟvity are felt locally.

Adyton’s commitment to community partnership extends beyond employment. During the year, the Company

supported the Books4PNG Kids charity by providing logisƟcs assistance to deliver educaƟonal materials to children

across Feni Island. ReflecƟng its confidence in the long -term future of the project, Adyton has also commi Ʃed to

supporƟng the recommissioning of the Babase Island airstrip and is funding a clean water supply project for the

nearby Pikan village, both tangible investments that leave a lasƟng posiƟve legacy alongside exploraƟon success.

Fergusson Island

In May 2024, Adyton entered into a Joint Venture agreement with East Vision Investment Holdings (EVIH) providing

EVIH with the right (subject to the achievement of defined milestones) to earn a 50% stake in the Fergusson Island

projects. Importantly the agreement establishes a clear pathway for EVIH’s parent company to provide all required

project financing, significantly de-risking development and funding execuƟon.

Throughout the year, substan Ɵal progress was made at Fergusson Island. 8000 metres of drilling were completed

across the Wapolu and Gameta projects, alongside comprehensive landowner engagement, and the compleƟon of

social and environmental base line studies. Metallurgical test work has advanced to a stage that supports

confirmaƟon of the proposed process flow sheet, and the Company recently executed its first non-binding LeƩer Of

Intent for the purchase of Wapolu concentrate, an important milestone.

Near term ac ƟviƟes are focused on comple Ɵng feasibility studies, submi ƫng Environment permits and advancing

the Mining Lease applicaƟon. In parallel, Adyton is finalising agreements with EVIH to accelerate development at the

Gameta project, posiƟoning Fergusson Island for a clear and well-defined path toward producƟon.

Our key deliverables for 2026

Feni Island – 2026 PrioriƟes

 ConƟnue drilling and resource expansion at Feni Island including tesƟng targets beyond the Kabang resource

footprint. The primary objecƟve is to demonstrate that the scale and con Ɵnuity and the structural controls

of the Feni system support expansion of the resource targe Ɵng greater than 5 Moz with an increasing

proporƟon of Indicated resources that underpin feasible and economic mining scenarios;

 Target the release of an updated Mineral Resource EsƟmate (MRE) In H2 2026;

 Advance a preliminary assessment of the geothermal energy potenƟal on the Island, evaluaƟng its suitability

as a future low-carbon or carbon-neutral power source for a potenƟal mining operaƟon; and

 Apply modern exploraƟon vectoring and targeƟng tools to refine geological models and build convic Ɵon in

new, large-scale exploraƟon targets across the broader Feni system.

Fergusson Island – 2026 PrioriƟes

 Complete feasibility workstreams and submit Environmental Permit and Mining Lease applica Ɵons to

support the restart of the Wapolu operaƟon;

 Secure granƟng of the ML and Environmental approvals, together with compleƟon of all required landowner

agreements;

 Commence operaƟons at Wapolu, marking a key transiƟon from development to cash flow generaƟon;

 ConƟnue infill drilling at Gameta to expand Indicated Resource, complemented by selecƟve step-out drilling

to test near-mine resource growth potenƟal; and

 Advance permiƫng at Gameta including submission of the Mining Lease and ML and Environmental Permit

applicaƟons and compleƟon of all baseline studies and landowner agreements.

None of this progress would have been possible without the dedication of our talented team, the guidance of the

Board and the continued support of our shareholders. I would particularly like to acknowledge the strong support of

our local landowners, especially the family of principal landowner, Vincent Terer, whose partnership is fundamental

to our ability to operate on Feni Island.

I also want to recognize the unwavering commitment of our employees, and particularly Dr. Chris Bowden, our senior

geologists and site leadership team Fred Iwei and Eugene Atase, along with all staff and local stakeholders who

contribute every day to our success.

Finally, I would also like to acknowledge the support of the Mineral Resources Authority along with Provincial and

Local Government support, whose leadership and assistance were instrumental in enabling Adyton to successfully

return to operations on Feni Island.
