Brisbane, Australia--(Newsfile Corp. - June 18, 2026) - Adyton Resources Corporation (TSXV: ADY) (OTCQB: ADYRF) (FSE: 701) ("Adyton" or the "Company") is pleased to announce that the Mineral Resources Authority (MRA) has approved Adyton's application to vary Exploration Licence EL 2549, enabling bulk sample extraction and processing at the Wapolu Gold Project as part of preparations for the recommencement of mining operations.

The approved variation permits the extraction and on-site processing of a bulk sample of approximately 20,000 tonnes for the purposes of process flow sheet optimisation, metallurgical testing, and the production of bulk concentrate samples for customer evaluation and product qualification.

"The approval of our Exploration Licence variation to enable bulk sampling is an important step forward in our strategy to restart mining operations at Wapolu," said Tim Crossley, Chief Executive Officer of Adyton. "The ability to mobilise ahead of Mining Lease approval enables us to accelerate key development activities including, metallurgical testing, process optimisation and the production of concentrate samples for customer qualification and pricing. This approval keeps us firmly on track as we work to unlock the value of this high-quality gold project and progress Wapolu towards production. We appreciate the MRA's timely and practical support as we advance the responsible redevelopment of this historic mine."

Louis Wang, Project Director of EVIH, commented:

"We are very pleased with the pragmatic approach adopted by the MRA throughout this variation process. Their willingness to work constructively with project proponents and support practical solutions that facilitate responsible project development is highly encouraging. The approval of this variation, together with the recent completion of the Mine Warden's Hearing, represents meaningful progress toward bringing the historic Wapolu Mine back into production."

Exploration Licence (EL) 2549, which hosts the Wapolu Gold Project, is currently the subject of an Environment Permit application, Mining Lease Application (ML) 1390, and Lease for Mining Purposes (LMP) 152. Together, these statutory approvals are intended to support the recommencement of mining operations at the historic Wapolu Mine. The ML application covers the proposed mining and processing activities, while the LMP application relates to supporting infrastructure, including facilities such as airstrips and associated project infrastructure.

Importantly, the Mine Warden's Hearing for ML 1390 was recently completed, representing a significant milestone in the permitting process and demonstrating continued progress toward securing the approvals required to restart mining operations. The approved variation to EL 2549 will enable Adyton to undertake advanced development and testing activities on the ground while the Environment Permit, Mining Lease and LMP applications continue through the approval process.

The Wapolu Project, together with the neighbouring Gameta licence area, represents two of the most advanced development assets on Fergusson Island. Both projects are being actively advanced through the permitting and development process by Adyton and EVIH.

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% 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 ‎Panguna copper-gold mine on Bougainville Island, both in close proximity to Feni, highlighting the district-scale potential of the Company's land package.

Feni Island Au-Cu project

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 on SEDAR+ at www.sedarplus.ca. Mineral resources are not mineral reserves and have not demonstrated economic viability.

Fergusson Island Au projects
