Brisbane, Australia--(Newsfile Corp. - January 13, 2026) - Adyton Resources Corporation (TSXV: ADY) ("Adyton" or the "Company") is pleased to announce an updated NI 43-101 Mineral Resource Estimate (MRE) for its Wapolu gold project on Fergusson Island, Papua New Guinea (PNG). The updated MRE is comprised of 1.0 million tonnes grading 1.00 g/t Au for an indicated resource of 33 koz Au and 12.7 million tonnes grading 0.97 g/t Au for an inferred resource of 393 koz Au. The estimate was prepared by Mining One under the authorship of Louis Cohalan (MAIG), an independent mining consultant ‎and "qualified person" as defined in NI 43-101.

The restart of the Wapolu gold project is an important pillar to Adytons strategy to achieve near term production and cash flow. The proposed initial Wapolu operation would be a shallow open pit ~300kt ROM operation with a simple crush, grind, float flow sheet to produce and market a gold rich concentrate. On the 10^th of December 2025, Adyton announced it had received a non-binding Letter Of Intent (LOI) from Korean trading group Hyosung TNC Corporation to purchase its Wapolu concentrate.

KEY HIGHLIGHTS

• Inferred Resource increases 197% - Wapolu MRE increases Indicated Resources to 33 koz and Inferred Resources to 393 koz, adding 226 koz versus the prior estimate, confirming strong growth potential at Fergusson Island.
• Attractive grade profile - Near-surface, open pit resource grading ~1.0 g/t Au (1.00 g/t Indicated; 0.97 g/t Inferred), supportive of simple, low-cost open-pit mining development scenarios.
• Advances project toward permitting - Updated MRE represents a key milestone for the Mining Lease Application, materially de-risking the pathway to development.

"The updated Wapolu Mineral Resource materially strengthens the foundation of our Fergusson Island development strategy and exceeds our internal expectations," said Tim Crossley, Chief Executive Officer of Adyton. "The combination of a near-1.0 g/t gold grade and a more than doubled resource base enhances the potential for a larger, more flexible operation beyond the initially planned 300,000 tpa Run Of Mine scenario as we push towards a targeted start-up later this year. Additionally, development work is fully funded to production through our joint venture with EVIH. With this updated MRE increasing the total gold resources across Fergusson and Feni Islands, and further MRE updates at Gameta and Feni planned for 2026, Adyton is entering a clear growth and execution phase."

"EVIH is currently focused on supporting Adyton to restart operations at the Wapolu Mine," commented Gary Wang, Chief Executive Officer of EVIH. "This MRE is very positive for the project and will enable us to finalize the feasibility and financial modelling required to submit the Mining Lease application."

Gameta and Wapolu resources at 0.5g/t gold cut-off (see "About Adyton" for technical report references)

Notes to Table:
1. The effective date of the Wapolu Mineral Resource is 12 December 2025.
2. This Mineral Resource update only affects the Wapolu Exploration Licence, there has been no change to Gameta.
3. The Mineral Resource was estimated using the Canadian Institute of Mining, Metallurgy and Petroleum (CIM), Definition Standards for Mineral Resources and Reserves, as prepared by the CIM Standing Committee and adopted by CIM Council.
4. The estimate was prepared by Louis Cohalan, MAIG, an independent Qualified Person as defined in NI 43-101.
5. It is envisaged that the Wapolu deposit will be mined using open-pit mining methods.
6. The Mineral Resources are reported within an optimised pit shells and are considered to have reasonable prospects for eventual economic extraction based on these assumptions: gold recoveries of 90%, a gold price of 3500 A$/oz (Australian dollars per ounce), mining costs of 3.0 A$/t (Australian dollars per tonne), slope angle of 35 OSA, processing cost of 23 A$/t and G&A costs of 7 A$/t.
7. A cut-off grade 0.5 g/t Au was applied to the reported resource.
8. Gold grades were estimated within each of five modelled mineralisation domains using capped 1m composites applying Ordinary Kriging and Inverse Distance Squared estimation method.
9. An average density of 1.8 t/m³ was assigned for the Oxide zone while 2.5 t/m³ was assigned for the Fresh zone.
10. The CIM definitions were followed for the classification of Indicated and Inferred Mineral Resources on a lens by lens basis. The Indicated category was assigned for blocks in areas of 50mx50m grid drilling from the 2025 campaign, where surrounding diamond core had recoveries >85%. The Inferred category was assigned for blocks within 50m of drilling in areas of 100m x 100m grid drilling.
11. Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability. There is no certainty that all or any part of the mineral resources will be converted into mineral reserves in the future. The MRE may be materially affected by considerations including, but not limited to, permitting, legal, sociopolitical, environmental issues, market conditions or other factors.
12. Tonnes have been rounded to the nearest 100,000 t and ounces to the nearest 1000 ounces to reflect the relative accuracy of the estimate.

Resource Estimate

The existing Gameta and updated Wapolu Mineral Resource Estimates are highlighted in Table 1. The current drill programs at both Wapolu and Gameta are in part designed to test depth and strike extensions (with resources open at depth and along strike) but also importantly to increase resource confidence to enable progress to establish reserve estimates and Mining License (ML) applications.

Project Update and Key Next Steps

Adyton's JV partner, EVIH, has completed the current phase of drilling at both Wapolu and Gameta. While lab turnaround times in PNG have faced delays, Gameta samples have been dispatched to an international laboratory.

Key activities currently underway include:

• Finalizing work streams, reports and compensation agreements for the Mining Lease (ML) application.
• Submission of the Wapolu ML application.
• Responding to information requests from government departments.
• Finalizing equipment selection for long-lead items.
• Gameta, located only 30km away is being fast-tracked to leverage the Wapolu production infrastructure.

At Adyton's projects, numerous local jobs have been created, providing employment opportunities in areas with limited job prospects.

The Wapolu Restart Advantage

The Wapolu gold project is a proposed restart of the past-producing Wapolu mine which operated in the mid 1990's before shutting down due to low gold prices. The restart of Wapolu is expected to be significantly less complex than a greenfield development, supported by substantial existing infrastructure including airstrips, workshop and warehouse facilities, basic wharf infrastructure and established tailings impoundments.

Further Background

Adyton's gold projects are on easily accessible island locations in PNG. The Gameta and Wapolu projects (in JV with EVIH) are located on Fergusson Island in the Milne Bay province of PNG which also hosts the Woodlark and Misima projects (see Figure 1 and refer to map of PNG deposits at end of document).

The neighboring Gameta project represents an advanced exploration opportunity moving toward permitting and development. Located just 30 km from Wapolu, Gameta benefits from proximity to existing infrastructure, including the Wapolu airstrip, providing potential development and operating synergies.

EVIH Joint Venture

As previously reported, (see news release dated May 13, 2024) the Fergusson projects are under an earn-in Joint Venture Agreement with EVIH, granting EVIH the right to acquire up to 50% ownership interest in the project. This interest is contingent on the achievement of certain development milestones and a total investment of up to US$9.5 million, allocated as follows:

• US$8.5 million to fund project expenditures; and
  
  
• US$1.0 million as a direct payment to the Company (US$500,000 paid).
  
  
• Once the projects are permitted and a financial investment decision made by the JV, the agreement provides for EVIH to provide a shareholder loan (8% interest charge) to the JV to fund the project development capital which would carry Adyton to production on the Fergusson projects.

At full earn-in, the JV positions Adyton with a 50% interest at Fergusson while delivering a fully carried funding solution that advances the Fergusson projects through development and into production, preserving capital and minimizing risk for Adyton shareholders.
