Adyton Announces First Drill Samples from Latest Campaign at Its Feni Island Gold Project (With High Copper Prospectivity) Have Been Dispatched for Analysis

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.
