NEWS RELEASE
ADYTON RESOURCES INCREASES INDICATED RESOURCES BY 131% AT
FERGUSSON ISLAND GAMETA PROJECT
Brisbane, Australia – August 5, 2026 – Adyton Resources Corporation (TSX Venture: ADY, OTCQB: ADYRF, FSE:
701GR) (“Adyton” or the “Company”) is pleased to announce an updated NI 43-101 Mineral Resource Estimate
(MRE) for its Gameta Gold Project (“Gameta” or the “Project”) on Fergusson Island, Papua New Guinea ( PNG).
The Gameta Gold Project represents a key growth opportunity within Adyton’s Fergusson Island portfolio and is being
advanced alongside the Company’s Wapolu Project, where Adyton is targeting a potential restart of historical mining
operations in Q4 2026. The Gameta and Wapolu projects, held in partnership with East Vision International Holdings
(“EVIH”), are located on Fergusson Island in Papua New Guinea’s Milne Bay Province, a region that also hosts the
Woodlark and Misima gold projects.
Located approximately 30 kilometres east of the historic Wapolu mine, which operated during the mid-1990s, Gameta
benefits from its proximity to existing infrastructure and potential operational synergies with Wapolu. The Company
is evaluating a standalone processing facility at Gameta while leveraging shared resources, logistics advantages, and
existing infrastructure, including the Wapolu airstrip.
Both Gameta and Wapolu host near-surface mineralization that is being developed as open-pit mines. The continued
advancement of these projects provides Adyton with the opportunity to build a multi-asset gold development platform
on Fergusson Island.
UPDATED GAMETA MRE
The updated Gameta MRE incorporates approximately 4,000 metres of infill drilling completed in 2025 and
comprises an indicated mineral resource of 8.94 million tonnes grading 1.41g/t Au containing 404,000 ounces
of gold and an inferred mineral resource of 6.52 million tonnes grading 0.99g/t Au containing 207,000 ounces
of gold. 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.
131% Increase in Indicated Mineral Resource — the updated Gameta MRE increases the indicated mineral
resource by 131% to 404,000 ounces of gold, reflecting the success of the 2025 infill drilling program in
converting resources to the higher-confidence indicated category. The updated MRE strengthens the
geological model, provides an enhanced foundation for future engineering and development studies, and
confirms that mineralization remains open at depth and along strike to the southeast.
Higher Confidence, Improved Grade Near Surface Resource — the updated MRE comprises a near-surface
resource grading ~1.41g/t Au Indicated and 0.99 g/t in the Inferred category, supporting the evaluation of
potential open-pit mining development scenarios.
Strengthening the Path Towards Permitting — The updated MRE marks a significant milestone in the
advancement of the Project providing enhanced geological confidence and critical data to support future
permitting and development studies. The increase in higher-confidence Indicated resources strengthens the
technical foundation for ongoing environmental, engineering, and regulatory evaluations as Adyton continues
to advance Gameta toward potential development.
KEY HIGHLIGHTS
“The updated Gameta MRE represents a significant milestone for Adyton and reflects the success of our 2025 infill
drilling program in substantially increasing the higher-confidence indicated resource,” said Tim Crossley, Chief
Executive Officer of Adyton . “The 131% increase in indicated resource to 404,000 ounces of gold, together with an
indicated grade of 1.41 g/t gold highlights the quality and scale of the Gameta deposit. This updated MRE strengthens
our understanding of the project and provides an important platform as we advance technical studies, permitting
activities, and future exploration across Fergusson Island. With additional resource updates planned at Feni Island,
Adyton continues to build a larger, gold resource base across its Papua New Guinea projects.”
“Although EVIH is currently very focused on supporting Adyton to restart operations at the Wapolu Mine,” commented
Louis Wang, Project Director of EVIH. “This MRE is very positive for the broader Fergusson development and confirms
that Gameta is a much larger, richer, and more contiguous deposit than initially understood. This MRE will enable us
to finalize the feasibility and financial modelling required to submit the Mining Lease application.”
Fergusson Island Mineral Resource Estimate
The updated Gameta and Wapolu Mineral Resource Estimates are highlighted in Table 1. The drill programs at
both Wapolu and Gameta were 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.

Gameta and Wapolu resources at 0.4g/t gold cut-off (see “About Adyton” for technical report references)
Notes to Table:
1. The effective date of the Gameta Mineral Resource is 12 July 2026.
2. This Mineral Resource update only affects the Gameta Exploration Licence, there has been no change to
Wapolu (announced 13 January 2026), except to report it at 0.4 g/t Au cut-off instead of 0.5 g/t Au and to
deduct 2.5% royalty from the economic assumptions used to generate the RPEEE optimisation shell.
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 Gameta and Wapolu deposit will be mined using open-pit mining methods.
6. The Mineral Resources are reported within optimised pit shells considered to have reasonable prospects for
eventual economic extraction based on these assumptions: gold recoveries of 90%, a gold price of 3500 US$/oz,
overall slope angle of 35°, 2.5% royalty, mining costs of 3.0 US$/t, processing cost of 23 US$/t and G&A costs
of 7 US$/t.
7. A cut-off grade 0.4 g/t Au was applied to the reported resource.
8. Gold grades were estimated within individual mineralisation domains using hard boundaries, capped 1m
composites applying Ordinary Kriging and Inverse Distance Squared estimation method.
9. A bulk density of 1.8 t/m3 was used for Oxide and 2.5 t/m3 for Fresh rock at Wapolu and 2.0 t/m3 for Oxide and
an average of 2.47 t/m3 for Fresh at Gameta based on hundreds of measurements.
10. The CIM definitions were followed for the classification of Indicated and Inferred Mineral Resources on a
domain-by-domain basis.
a. At Gameta, 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.
b. At Wapolu, the Indicated category was assigned for blocks in areas of 50mx50m grid drilling from all
drilling campaigns and 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 10,000 t and ounces to the nearest 1000 ounces to reflect the
relative accuracy of the estimate.

Project Update and Key Next Steps
EVIH has completed the current phase of exploration drilling at both the Wapolu and Gameta projects, providing
important geological information to support ongoing technical studies and project advancement activities across
Fergusson Island.
Key activities currently underway include:
Advancing Wapolu toward potential near-term production – Progressing development activities at the
historic Wapolu mine, including construction of the Phase 1 process plant module, which is expected to be
completed in late September 2026.
Supporting the Wapolu Mining Lease application – Working closely with the Mineral Resources Authority of
Papua New Guinea (“MRA”) through its review process and responding to recommendations and information
requests associated with the potential grant of the Wapolu Mining Lease.
Advancing Gameta permitting activities – Initiating the technical and environmental workstreams required
to support the future submission of the Gameta Mining Lease application and associated environmental
approvals.
Progressing Gameta feasibility studies – Advancing key technical studies required to support the Gameta
Mining Lease application and evaluate potential future development scenarios.
Strengthening project development synergies – Leveraging the close proximity of Gameta, located
approximately 30 kilometres from Wapolu, to evaluate opportunities to utilize shared logistics, infrastructure,
and operational capabilities as the Fergusson Island projects continue to advance.
Adyton’s Fergusson Island projects are also delivering meaningful social and economic benefits within local
communities. The Company’s activities have created numerous employment opportunities for local residents,
providing jobs, training, and economic participation in regions where employment opportunities are limited. Adyton
remains committed to working collaboratively with local communities, government stakeholders, and its partners to
support responsible resource development in Papua New Guinea.
Feni Island Project (update)
Feni conƟnues to strengthen its posiƟon as Adyton’s flagship growth asset. Over the past six months, our exploraƟon
team led by Dr Chris Bowden and Eugene Atase has significantly advanced its understanding of the broader mineral
system through ongoing drilling, geological mapping, new surface exposures, assay results and the interpreta Ɵon of
mulƟple datasets into an increasingly robust exploraƟon model.
As our understanding of the project conƟnues to improve, so does our confidence in the district-scale potenƟal of Feni
and our ability to idenƟfy new areas of mineralisaƟon beyond the current Kabang resource.
Looking ahead, several important work programs will further accelerate explora Ɵon, including a comprehensive
ground-based IP geophysics survey, regional reconnaissance across the broader Feni Island land package, and
conƟnued evaluaƟon of the recently granted Babase Explora Ɵon License. Together these ini ƟaƟves are expected to
generate a significant pipeline of new drill targets both around and beyond Kabang , including poten Ɵal deeper or
offset porphyry systems. Our objective is simple: to substantially increase the number of high-quality exploration
opportunities across the Feni district and continue building a pipeline of discoveries capable of creating long-term
value for our shareholders.
