CEO.CA Chairman's Briefing

Brisbane, Australia--(Newsfile Corp. - April 30, 2026) - Adyton Resources Corporation (TSXV: ADY) ("Adyton" or the "Company") announces that it has filed its financial statements for the twelve months ended December 31, 2025 and accompanying Management Discussion and Analysis on its SEDAR+ profile at www.sedarplus.ca.

KEY HIGHLIGHTS

• Successful C$20 million financing:

The Company completed a non-brokered/brokered financing for gross proceeds of C$20 million, strengthening its balance sheet and providing sufficient capital to advance exploration activities predominantly focused on the Feni project while the continued advancement of the Fergusson projects are funded through the East Vision International Holdings ("EVIH") JV earn-in structure.

• Fiscal discipline and strong year-end cash position:

The Company maintained a disciplined approach to capital allocation throughout the year, ensuring efficient deployment of funds across exploration programs. As a result, the Company ended the year with a combined cash and cash equivalents and other financial assets (Term Deposits) of C$18.3 million at December 31, 2025 (2024: C$6.9 million), providing a solid foundation for planned activities in the upcoming period.

• Appointment of Michael Gray to the Board of Directors:

The Company strengthened its Board with the appointment of Michael Gray, Co-Founder of Agentis Capital. Michael brings extensive experience in technical, corporate and capital markets experience. His expertise will play a key role in advancing the Company's strategic growth and development objectives.

• Commencement of drilling at Feni:

The Company successfully commenced its inaugural drill program at the Feni Gold-Copper Project, marking a significant milestone in advancing the asset beyond the Kabang resource footprint. The primary objective is to demonstrate that the scale and continuity and the structural controls of the Feni system support expansion of the resource that underpin feasible and economic mining scenarios.

• Successful 8,000 metre drilling program at Fergusson Island Projects:

The Company, through its strategic partner, EVIH, completed approximately 8,000 metres of drilling across the Fergusson Island projects, including Wapolu and Gameta. The program was executed on time and within budget, targeting resource expansion and conversion, with results supporting continued confidence to advance the projects into development.

• Updated Mineral Resource Estimate at Wapolu:

On January 13, 2026, the Company reported 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 restart of the Wapolu gold project is an important pillar to Adyton's 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.

• Strong community support across all projects:

The Company continued to foster positive relationships with local communities and stakeholders across both Feni Island and Fergusson projects. Ongoing engagement initiatives and responsible operating practices have contributed to strong community support, which remains critical to the successful advancement of exploration activities.
