Brisbane, Australia--(Newsfile Corp. - May 5, 2026) - Adyton Resources Corporation (TSXV: ADY) (" Adyton " or the " Company ") is pleased to report the discovery of a new high-grade gold zone within the existing resource, from its 2025 infill drill program at the Gameta Gold development Project (50/50 JV), located on Fergusson Island in Papua New Guinea (PNG).

The 2025 program included 4201 meters of largely infill drilling for a total of 36 diamond core holes. Drilling focused on areas within the existing deposit to better define and expand known mineralization. Prior to this drilling, the Gameta Project's Mineral Resource Estimate (MRE) contained approximately 4.0 million tonnes (Mt) @ 1.33 g/t Au for 173 koz gold (indicated), and 10.5 Mt @ 1.01 g/t Au for 340 koz gold (inferred), within a conceptual open-pit shell.

Hole GMDH009 returned 28.56 g/t Au over 12.0m starting from 146m downhole. This is the highest-grade intercept ever recorded by Adyton to date and highlights the presence of high-grade zones within the broader deposit. This result, along with other strong intercepts reported in this release, demonstrates the potential to enhance the overall grade of the planned open- pit at Gameta. These higher-grade zones could positively impact the upcoming Feasibility Study being advanced by Adyton and its JV partner EVIH.

KEY HIGHLIGHTS

Final assays from the 2025 infill drill program highlight the presence of locally high-grade zones at Gameta including the project's best intercept to date of 12m @28.56 g/t Au returning 342 g-m.

Significant intercepts include:

GMDH009 12m @ 28.56g/t Au from 146 m downhole
GMDH008 13m @ 3.84g/t Au from 98 m downhole
GMDH021 16m @ 2.2.07g/t Au from 51 m downhole
GMDH010 6m @ 2.69g/t Au from 114 m downhole
GMDH005 13m @ 1.88g/t Au from 49 m downhole
GMDH013 13m @1.37g/t Au from 105 m downhole
GMDH005 14m @1.05 g/t Au from 94 m downhole

Several holes also intersected near surface mineralization with solid grades including hole GMDH001 with 9m @ 1.08g/t Au and hole GMDH002 6m @ 1.22g/t Au (see Table 1 below).

These infill drill results have exceeded the Company's expectations and are expected to support an updated MRE, with several intersections returning grades above those reflected in the current model. The results may also support the conversion of a significant portion of the inferred resource to the indicated category.

"I am very pleased with these results, which have exceeded our expectations and highlight the strength of the Gameta Project," said Tim Crossley, Adyton CEO. "The project combines solid grades, near surface mineralisation, and favourable logistics, including access for barge transport to support envisioned development and concentrate shipment to end markets. We are now focused on advancing Gameta alongside the Wapolu Project, accelerating toward feasibility and permitting, with the goal of developing Gameta into a second production asset. Our vision for these projects is to unlock near-term cash flow through a disciplined Direct Ship concentrate strategy, while establishing a scalable foundation for long-term growth and value creation across the portfolio."

"We are encouraged by the assay results at Gameta and, together with Adyton, plan to advance the project through MRE finalisation, Feasibility Studies, and permitting. Subject to permitting timelines, we are targeting a potential start of operations in the first half of 2028," said Gary Wang, EVIH CEO.

CATALYSTS & OUTLOOK

1) Fergusson Island Project (PNG):
Focused on advancing the Wapolu and Gameta deposits toward potential production and cash flow. Current resources include:

Wapolu: 33,000 oz Au (Indicated) and 393,000 oz Au (Inferred) Gameta: 173,000 oz Au (Indicated) and 340,000 oz Au (Inferred)

Key Fergusson Island catalysts include:

Updated MRE at Gameta (second half 2026) Permitting milestones (Q3 2026) Construction and potential commencement of operations at Wapolu (second half 2026)

2) Feni Island Project (PNG):
A 1.45-million-ounce gold alkalic gold-copper project located in the Bismarck Island chain, with geological similarities to the Lihir Gold Mine.

Key Feni Island catalysts include:

A high-resolution 5 km by 5 km induced polarization (IP) survey in Q2 2026, designed to support near-term resource development and broader project targeting A follow-up drill program to systematically test priority targets identified from the survey

QUALITY ASSURANCE / QUALITY CONTROL
Samples were analysed at the Sichuan Xiye Testing Technology Laboratory (SXTT) in China and QA/QC was verified using certified reference materials, blanks and duplicates that were blind to the lab.

In addition to this routine verification, 71 samples were selected among the highest-grade intervals and were re-submitted for assaying to confirm results. Assays replicated well and give confidence to the results.
