Adyton Reports 6.60gt Au, 2.44% Cu and 39.8gt Ag within 164m @ 0.82gt AuEq Including 53m at 1.60gt AuEq within 164m at 0.82gt AuEq from the Northeastern Extension Target, Feni Island

About this update from Adyton Resources Corporation

Brisbane, Australia - Adyton Resources Corporation (TSXV: ADY) ('Adyton' or the 'Company') is pleased to announce positive expansionary drill results from its ongoing exploration program at the 100% owned Feni Island Gold-Copper Project, located on the productive Lihir Trend, Papua New Guinea (PNG). This announcement provides all the assay results for expansionary hole FDD017 (preliminary results were first reported on February 18, 2026). Hole FDD017 previously returned 53m @ 1.29g/t Au (gold only) and now, incorporating newly released copper assays, reports as 53m @ 1.60g/t AuEq representing an approximate 25% increase in reported grade. In addition, strong silver (Ag) and molybdenum (Mo) results further support the presence of a highly fertile epithermal-porphyry at Kabang. KEY HIGHLIGHTS OF DRILL HOLE FDD017 Final assays for hole FDD017 have delivered another >100gm intercept, further confirming strong Au-Cu mineralisation in the north-eastern extension target Hole FDD017 yielded: 53m @ 1.29g/t Au, 0.26% Cu (1.60g/t AuEq; from 151m) within a broader interval of 164m at 0.63g/t Au, 0.15% Cu (0.82g/t AuEq for 134gm; from 36m); including a higher-grade interval that returned: 5m @ 3.6g/t Au, 1.48% Cu (5.63g/t AuEq: from 198m) In addition to gold and copper, FDD017 also reports significant silver and molybdenum signalling strong system fertility for a large alkalic epithermal-porphyry system: 5m @ 22.3g/t Ag (from 198m) and 6m @ 275ppm Mo (from 295m; peak Mo 579ppm) These final assay results for hole FDD017 confirm the North-Eastern zone at Kabang is strongly mineralised and prospective for gold and copper and continues to expand this zone beyond the current resource model. Ground based IP/MT survey progressing well; looking to deploy within 2Q 2026. 'FDD017 continues to exceed our expectations, delivering a meaningful uplift in grade with the inclusion of copper and highlighting the strength of the broader mineralized system at Feni. The increase to 1.60g/t AuEq over 53 metres, combined with strong silver and molybdenum values, reinforces our view that Kabang represents a highly fertile and evolving epithermal-porphyry system. Importantly, this hole further confirms the scale and continuity of mineralization in the north-eastern extension, which remains open and continues to grow beyond the current resource footprint.' said Tim Crossley, CEO. Adyton is looking forward to receiving additional assays from nearby drillholes within this zone and updating the market accordingly. FUTURE CATALYSTS & OUTLOOK Adyton is well-funded with C$16.75m in cash and cash equivalents, 100% earmarked for the Feni Au-Cu Project (plus G&A). The company is executing a systematic exploration strategy to grow the MRE and discover new deposits. Upcoming results and milestones include: Pending Assays: NNE: FDD018, FDD020, FDD023, FDD025, FDD029 SSW: FDD019, FDD021, FDD024, FDD026, FDD028 Ongoing Drilling: focused on expanding the MRE footprint at Kabang, and testing new targets. Advanced Geophysics: An approximately 5km by 5km ground-based IP & MT survey is being scoped to detect additional deposits on Feni Island and detect deeper prospective targets for drilling. Spectral Mapping: Deployment of pXRF as well as spectral mineral mapping (1Q 2026) to generate a 3D alteration model for precise vectoring toward the core of the mineralized system with potential high Au-Cu grades to target for drilling. FERGUSSON ISLAND PROGRESS UPDATE EVIH, our 50/50 JV partner, continues to make good progress on the restart of the Wapolu Au Mine. Key areas of significant progress include purchasing and shipping of long lead items and processing plant components. The Mineral Resources authority have also set the date for the ML application Wardens Hearing for May 21, 2026. It is expected that, subject to permitting, Wapolu could be in production in Q4 2026. Adyton does not have any capital expenditure requirements for the Wapolu, these are being provided by EVIH as part of the JV earn-in to the Fergusson projects. ABOUT THE FENI GOLD-COPPER PROJECTThe Feni Project is 100% owned by Adyton and is a key asset in Adyton's portfolio, located in a highly prospective region of Papua New Guinea on the Lihir Island chain known for world-class gold-copper deposits, including Lihir (owned and operated by Newmont). The Company has confirmed significant gold-copper mineralization at Feni, with a focus on expanding its existing resource and identifying new high-grade targets.

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 projectThe 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. Mineral resources are not mineral reserves and have not demonstrated economic viability. Fergusson Island Au projectThe Fergusson Island Project currently has a mineral resource prepared in accordance with NI 43-101, which outlined an indicated mineral resource of 5.0 million tonnes at an average grade of 1.28 g/t Au 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 0.5g/t Au cut-off grade.
