Brisbane, Australia--(ACN Newswire - March 25, 2026) - 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 >100g*m 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 134g*m; 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.

The dashed red arcuate line outlines the extent of anomalous Mo and is interpreted to denote the porphyry mineralization footprint based on drilling to date. The green arrow is the vector towards epithermal mineralization based on As-Sb pathfinder elements increasing to the SSW. Pending assays and future drilling will increasingly allow the company to hone-in on porphyry-related and epithermal-related Au-Cu mineralization.

Figure 4: This long section utilizing recently reprocessed mag and IP data shows the now apparent close correlation of the Danmagal porphyry system evidenced at depth by magnetics data (red polygon >0.16MVI) and the close spatial relationship of the Kabang epithermal system (orange 27mRad IP anomaly) and known gold grades. Of note, geochemical zonation appears to be vectoring towards a hydrothermal fluid source to the SW and to depth - exactly where the Danmagal porphyry is located. Furthermore, the Kabang drilling has encountered smaller apophyses of porphyry style intrusives and copper mineralization, and the current geological model suggests that Danmagal is the likely source of these.

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 (see Figure 1).
- 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.
QUALITY ASSURANCE / QUALITY CONTROL
Adyton adheres to industry-recognized standards of Best Practice and Quality Assurance/Quality Control (QA/QC). Drill core samples were submitted in batches to Intertek Laboratory in Lae, which include a field blank, certified reference materials (CRMs) and staged duplicates. Samples were sealed ensuring Chain of Custody. To date, all batches have passed QA/QC, and blanks and CRMs were within acceptable tolerance limits. All drill holes were drilled and sampled predominantly from PQ and HQ diameter drill core, and to a lesser extent, also NQ core. Core recovery is considered to be appropriate.
