ADYTON RECEIVES WAPOLU ENVIRONMENTAL PERMIT, ADVANCING RESTART OF HISTORIC GOLD MINE

The Papua New Guinea Conservation and Environment Protection Authority (CEPA) has granted the environmental permit EP-L2(1080) to Adyton Resources Corp.'s Wapolu project.

The grant of the environment permit marks an important milestone in the responsible redevelopment of the Wapolu project. 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).

"The grant of the Wapolu environment permit is a significant derisking milestone and reflects the considerable work undertaken by our team, government agencies, local landowners and communities to responsibly advance the project," said Tim Crossley, chief executive officer of Adyton. "We are committed to redeveloping Wapolu in a manner that creates lasting value for all stakeholders. We appreciate the collaborative approach taken throughout this process and look forward to working with the MRA, CEPA, our host communities and all stakeholders as we progress the remaining approvals required to restart mining operations."

Louis Wang, project director of EVIH, commented: "We are pleased to have received the environment permit for Wapolu and appreciate CEPA's engagement throughout the assessment process. This approval is an important step in advancing the project toward the restart of operations."

As previously announced on June 8, 2026, the company received approval from the MRA for a variation to exploration licence EL 2549, which hosts the Wapolu gold project, 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 tonnes per annum run of mine) at Wapolu, which remains on target for Q4 2026.

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

Adyton Resources 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-per-cent-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 the Panguna copper-gold mine on Bougainville Island, both in close proximity to Feni, highlighting the district-scale potential of the company's land package.

Fergusson Island gold projects

The Fergusson Island projects currently have a mineral resource prepared in accordance with National Instrument 43-101, which outlined an indicated mineral resource of 5.0 million tonnes at an average grade of 1.28 grams per tonne gold for contained gold of 206,000 ounces and an inferred mineral resource of 23.2 million tonnes at an average grade of 0.99 g/t Au for contained gold of 733,000 ounces; both inferred and indicated resources used a 0.5-gram-per-tonne-gold cut-off grade, refer to the table below for a breakdown of the Fergusson Island projects' mineral resources.
