Brisbane, Australia--(Newsfile Corp. - August 26, 2026) - Adyton Resources Corporation (TSXV: ADY) (OTCQB: ADYRF) (FSE: 701) (" Adyton " or the " Company ") announces that it has filed its financial statements for the six months ended June 30, 2026 and accompanying Management Discussion and Analysis on its SEDAR+ profile at www.sedarplus.ca .

KEY HIGHLIGHTS

Fiscal discipline and strong quarter-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 period with a combined cash and cash equivalents and other financial assets (Term Deposits) of $13.4 million at June 30, 2026, providing a strong foundation for planned activities in the upcoming period.

Updated Mineral Resource Estimate for the Fergusson Gameta Project: On August 5, 2026, the Company reported an updated NI 43 101 Mineral Resource Estimate (MRE) for its Gameta Gold Project ("Gameta") on Fergusson Island, Papua New Guinea (PNG). 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.

Fergusson Island Mineral Resource Estimate

The updated Gameta and Wapolu Gold Project ("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.

Continued achievements of major mining milestones at the Fergusson Wapolu Gold Project On July 6, 2026, the Company reported that the Papua New Guinea Conservation and Environment Protection Authority (CEPA) granted the Environment Permit EP-L2(1080) for Wapolu. The permit confirms that the Project's environmental management plans have satisfied the requirements of the CEPA framework and supports Adyton's commitment to developing Wapolu in an environmentally responsible manner, in partnership with local communities and stakeholders. With this approval now in place, the remaining key regulatory milestones for the recommencement of mining operations are the grant of a Mining Lease and a Lease for Mining Purposes, both of which are administered through the Mineral Resources Authority (MRA). On June 8, 2026, the Company reported it had received approval from the MRA for a variation to Exploration Licence 2549 ("EL 2549"), enabling the extraction and processing of an approximately 20,000 tonne bulk sample. The approval of the EL 2549 variation, together with the grant of the Environment Permit, represents meaningful progress toward the restart of mining and processing operations (300,000 tpa ROM) at Wapolu.

Continued Drilling on Feni Island Continued advancement of drilling activities at Feni Island through the quarter ending June 30, 2026 despite continued challenging rainy season conditions.

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.
