ADYTON REPORTS HIGH-GRADE INTERVAL AT GAMETA DEVELOPMENT PROJECT OF 28.5G/T AU OVER 12.0M INCLUDING 226G/T AU OVER 1.0M, FERGUSSON ISLAND, PNG

Adyton Resources Corp. has discovered a new high-grade gold zone within the existing resource from its 2025 infill drill program at the Gameta gold development project (50/50 joint venture), located on Fergusson Island in Papua New Guinea.

The 2025 program included 4,201 metres 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 contained approximately 4.0 million tonnes of 1.33 grams per tonne gold for 173,000 ounces gold (indicated) and 10.5 Mt of 1.01 g/t Au for 340,000 oz gold (inferred), within a conceptual open-pit shell.

Hole GMDH009 returned 28.56 g/t Au over 12.0 m starting from 146 m 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 coming 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 12 m of 28.56 g/t Au.
• Significant intercepts include:
  • GMDH009: 12 metres of 28.56 grams per tonne gold from 146 m downhole;
  • GMDH008: 13 m of 3.84 g/t Au from 98 m downhole;
  • GMDH021: 16 m of 2.2.07 g/t Au from 51 m downhole;
  • GMDH010: six m of 2.69 g/t Au from 114 m downhole;
  • GMDH005: 13 m of 1.88 g/t Au from 49 m downhole;
  • GMDH013: 13 m of 1.37 g/t Au from 105 m downhole;
  • GMDH005: 14 m of 1.05 g/t Au from 94 m downhole.
• Several holes also intersected near-surface mineralization with solid grades including hole GMDH001 with nine m of 1.08 g/t Au and hole GMDH002 with six m of 1.22 g/t Au (see table 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 chief executive officer. "The project combines solid grades, near-surface mineralization 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 finalization, 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 chief executive officer.

Catalysts and 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 ounces 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 (third quarter 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 five-kilometre-by-five-kilometre induced polarization survey in second quarter 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 analyzed at the Sichuan Xiye testing technology laboratory 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 resubmitted for assaying to confirm results. Assays replicated well and give confidence to the results.

About Adyton Resources Corp.

Adyton Resources Corporation is focused on advancing gold and copper projects in world-class mineral jurisdictions. The company holds a portfolio of highly prospective assets in Papua New Guinea, where it is actively working to expand its existing gold inferred and indicated mineral resources and build on recent high-grade gold and copper drill results at its 100-per-cent-owned Feni Island project.

Adyton's projects are located on the Pacific Ring of Fire, on accessible island settings that host several globally significant deposits, including the Lihir gold mine and the Panguna copper-gold mine on Bougainville Island, both in close proximity to Feni, highlighting the district-scale potential of the company's land package.
