Port Moresby, Papua New Guinea--(Newsfile Corp. - April 29, 2025) - Adyton Resources Corporation (TSXV: ADY) ("Adyton" or the "Company") is pleased to provide an update on its ongoing drilling activities at its 100% owned Feni Island project.

KEY HIGHLIGHTS

• The first batch of Feni drill samples have been prepared for dispatch to Intertek laboratory.
• The first barge resupply of fuel and other items at Feni demonstrated the ease of access for resupply by large existing coastal supply barges.
• At Adyton's Feni Island project, approximately 90 local jobs have been created, providing employment opportunities in areas with limited job prospects.

The current drill program is focused on the Kabang Prospect in order to twin select holes and assay for copper from holes previously drilled with no copper assays enabling copper to be included in the future MRE, whilst at the same time targeting open extensions and high-grade gold zones proximal to the current MRE.

Tim Crossley, Chief Executive Officer, stated:

"Significant progress is being made at the 100% owned Feni Island project, with our drill programme now well underway and first batch of drill samples already dispatched to the Laboratory in Lae, PNG's second largest city. It is also pleasing to note that approximately 90 new direct local jobs have been created along with several local businesses benefiting from the projects activities. Of course, it goes without saying that none of this activity would have been possible without the support from our local stakeholders and in particular the Feni Island Landowners."

Background

The Adyton projects are located in PNG on easily accessible island locations. Feni Island is part of the Tabar to Feni island chain which also hosts the operating gold mines of Simbiri (8 M oz) and Lihir (87 M oz) while Feni hosts a foundation resource of 1.45 M oz Au. To the southeast of Feni on Bougainville Island lies the giant Panguna deposit (23 Moz Au, 6.3 Mt Cu).

The Current Drill Program

Adyton began its drilling campaign at Feni Island targets in February of 2025. Two diamond drill rigs were deployed at site (i.e. Kabang). The focus of this program has been:

• A number of historical holes will be twinned in order to provide copper assays for input into an updated MRE. Evidence from Adyton drill holes, which were assayed for gold and copper, indicates inclusion of copper assays in the MRE would positively impact both grade and tonnage of an Au Eq. MRE. Twinned holes will also be taken to deeper target depths to test depth extension of mineralization.

• Step-out and step-back drill holes will target the strike and depth extensions of mineralization which are open in all directions. This includes infill drilling within the existing resource model where historical holes failed to penetrate post-mineralization cover.

• High grade breccia zones beneath the existing resource are high reward targets. A number of deeper holes (approx. 400 m) will target these zones.

Copper Potential

Feni Island displays multiple Lihir-style gold and copper targets. On the island, there is a central caldera complex that occurs within a NW-SE (TLTF parallel) trending pull-apart basin with low magnetic response. Within the Caldera complex the Kabang, Dome, Saddle and Caldera targets are analogous to the structural and geological setting of the Lihir deposits.

High reward gold-copper alkalic-type epithermal targets including Kabang (current MRE of 1.46 Moz Au) and its surrounding extensions (not drill tested), as well as Dome, Saddle and Caldera prospects, as well as high resolution drone geophysical targets.

Not all historical holes were assayed for copper - yet several holes that were assayed for copper returned significant copper assays over large down-hole intervals. Previous drilling by Adyton and explorers prior to Adyton confirmed the presence of near surface gold-copper mineralization and high-grade copper-gold mineralization beneath and proximal to the existing Kabang MRE.

It is notable that neither copper nor Adyton's successful 2021 drill holes have been included in the current Kabang MRE of 1.46 Moz Au.

The Company notes that it has laid a strong foundation for its work programs across all of its projects and will continue executing these programs at its 100% owned Feni Island project (see Figures 1 and 2). The near-term focus will be on continuing drilling at Feni Island. The Company will also be receiving and interpreting assay results from all three of its projects as they are received from the Intertek laboratory.

ABOUT ADYTON RESOURCES CORPORATION

Adyton Resources Corporation is focused on the development of gold and copper resources in world class mineral jurisdictions. It currently has a portfolio of highly prospective mineral exploration projects in Papua New Guinea on which it is exploring to expand its identified gold Inferred and Indicated Mineral Resources and expand on its recent significant copper drill intercepts on the 100% owned Feni Island ‎project. The Company's mineral exploration projects are located on the Pacific Ring of Fire on easy to access island locations which hosts several globally significant copper and gold deposits including the Lihir gold mine and ‎Panguna copper/gold mine on Bougainville Island, both neighboring projects to the ‎Company's Feni Island project.

Adyton has a total Mineral Resource Estimate inventory within its PNG portfolio of projects comprising indicated resources of 173,000 ounces gold and inferred resources of 2,000,000 ounces gold.

The Feni Island Project currently has a mineral ‎resource prepared in accordance with NI 43-101 dated October 14, 2021, which has outlined an initial inferred ‎mineral resource of 60.4 million tonnes at an average grade of 0.75 g/t Au, for contained gold of 1,460,000 ounces, ‎assuming a cut-off grade of 0.5 g/t Au. See the NI 43-101 technical report entitled "NI 43-101 Technical Report on the Feni Gold-Copper Property, New Ireland ‎Province, Papua New Guinea prepared for Adyton Resources by Mark Berry (MAIG), Simon ‎Tear (MIGI PGeo), Matthew White (MAIG) and Andy Thomas (MAIG), each an independent mining consultant ‎and "qualified person" as defined in NI 43-101,available under Adyton's profile
