Port Moresby, PNG – July 22, 2025 – Adyton Resources Corporation (TSX Venture: ADY) ("Adyton" or the "Company") is pleased to report its first preliminary gold only assays from three diamond drill holes and provide an update on its ongoing 2025 drilling activities. This news release is also designed to provide new geological observations on drillholes pending assays at its 100% owned Feni Island project.
Highlights
- Preliminary gold assay results have been returned for the first three (3) drillholes of this drill program at the Feni Island Project (no multi-element assay results or final gold assay results). Results show very consistent and broad gold zones in all three drillholes:
- FDD001: 76m @ 1.43g/t Au (from 95m) for 108gxm
- FDD002: 144.2m @ 1.18g/t Au (from 45m, EOH) for 170gxm; including 93m @ 1.58g/t Au (from 45m) for 147gxm
- FDD003: 81m @ 1.12g/t Au (from 70m) for 90gxm
- As of July 21, 2025, ten (10) diamond drillholes for 3,332m have been drilled with six (6) drillholes completed, one (1) terminated early, two (2) in-progress and one (1) abandoned. Sawn core samples from drillholes FDD001 through to FDD005 have been dispatched to the laboratory.
- Target hole depths are typically 400m. FDD001 and FDD002 reached 396m and 196m respectively (FDD002 terminated prematurely due to operational issues). FDD003 and FDD004 ended at 421.7m and 453.2m. Due to significant visual mineralization, FDD005 was drilled to 839m and terminated with visual mineralization still observed at EOH. FDD006 and FDD007 were terminated at 412m and 468m respectively.
- The preliminary assay results for the first three holes confirm that observations of shallow sulphide-mineralised hydrothermal breccias are consistently gold bearing.
- Similar — and stronger and deeper — visual sulphide mineralised breccias have been observed in FDD004, FDD005, FDD006 and FDD007.
Cautionary Statement: Observations of mineralization do not necessarily accurately predict true laboratory determined assay mineralization. Analytical assay results are pending and required to confirm the presence and grade of mineralization.
Tim Crossley, Chief Executive Officer, stated:
"These preliminary gold assays are very encouraging and demonstrate consistently greater than 100 gram/metre grade intercepts at relatively shallow depths. Subsequent to these holes being drilled we have tested for deeper mineralized extensions outside of the existing block model and we have had success with strong visual observed mineralisation to end of the holes. In particular, hole FDD005 was drilled to 839m and showed visual mineralisation from 45m through to end of hole, for a 794m mineralized interval. This hole in particular has generated a lot of excitement with our geology team as we await with interest for the assays to be reported."
Dr Chris Bowden, COO and Chief Geologist, commented:
"We are encouraged by what we are seeing in the drill core from this round of drilling at the Feni Island project. Initial assay results (preliminary gold only) for the first three drillholes confirm the geological model for the shallow, gold-bearing hydrothermal breccias encountered just below the base of the post-mineral tephra cover. These initial assay results give us confidence in the additional drillholes that also show visual observations of strong sulphide mineralisation within similar breccias, plus the upside of the deeper porphyry-style mineralisation (still pending assays)."
Significant Intercepts and Geology
Significant Intercepts received to date are based on preliminary gold assays for the first three drillholes. Gold equivalent calculated as: Au.eq = (Au g/t + 1.12(Cu %)). 'gxm' is the sum product of gold grade and widths.
Visual Results — Geological Observations from Core Logging
FDD004 Drillhole
FDD004 tested the Gap between the Kabang and Matangkaka mineralized zones that include the MRE. From the base of tephra to end of hole (EOH), FDD004 intersected variably mineralized breccias and intrusive units.
- Hydrothermal breccias showing strong sulphide mineralization from base of tephra (45m) to 111m.
- Intrusives to intrusive breccias showing disseminated and veined mineralization from 111m to EOH — including porphyry-style alteration assemblage of secondary biotite-magnetite-actinolite-chalcopyrite with stockwork pyrite-chalcopyrite-magnetite veining.
FDD005 Drillhole
FDD005 was designed to test the Gap between Kabang and Matangkaka zones and east of FDD004, drilled to a depth of 839.60m through hydrothermal breccias, diorites, microdiorite, monzodiorite and andesitic dykes with widespread sulphide mineralization from surface to over 800m depth downhole.
- Hydrothermal breccias with strong sulphide mineralization from base of tephra to depth.
- Semi-massive sulphides (up to 10%) in brecciated zones (e.g., 89.7m to 96.0m).
- Stockwork veining and fine disseminated sulphides over broad intervals from 120m to 347.6m and 450m to 616.1m.
- Deep, continuous veining and disseminated mineralization within altered monzodiorite from 743m to 829.1m (EOH), with 2–4% sulphide content.
FDD006 Drillhole
FDD006 is testing the northeast extension of Matangkaka zone and is outside any previous drilling. Drilled to 412.6m, the upper 69m intersected tephra cover; from 69m to EOH the hole intersected extensive hydrothermal breccias and mineralized intrusives.
- 69m to 207m: hydrothermal breccias with strong sulphide mineralization.
- 207m to 315m: fine- to medium-grained intrusive rocks with pervasive chlorite-silica-pyrite alteration, 2–5% disseminated pyrite and up to 1% chalcopyrite.
- 315.2m to 316.6m: vein-hosted quartz-magnetite-pyrite-chalcopyrite (Cu up to 1%).
- 320.2m to 360.1m: strongly brecciated intrusive rocks with sulphide-rich matrix infill.
- 360.1m to 412.6m: polymictic hydrothermal breccia with 2–4% sulphides, including clasts exceeding 5% sulphide content.
FDD007 Drillhole
FDD007 is testing the lateral extent of the gold-bearing hydrothermal breccias in a north to northwesterly direction, north of FDD005. Drilled to 468.20m, the hole encountered extensive hydrothermal breccias and a range of intrusive units with widespread disseminated and fracture-hosted sulphides (primarily pyrite, chalcopyrite, arsenopyrite) locally reaching 6–10%.
- 63.2m to 100.0m: hydrothermal breccia with strong pyrite and chalcopyrite mineralization.
- 100.0m to 133.7m: silicified zones and fractured monzodiorite with up to 6% total sulphides.
- 133.7m to 175.2m: intensely fractured monzodiorite with pyrite, chalcopyrite, arsenopyrite up to 6%.
- 221.0m to 243.2m: strongly mineralized hydrothermal breccia zone with 5–10% sulphides and intense silica-clay alteration — potential high-grade gold zone.
- 243.2m to 350.7m: fractured monzodiorite and diorite with consistent sulphide content (3–6%) and strong quartz-anhydrite veining.
- 370.1m to 427.7m: pervasively altered diorite with increasing sulphide intensity, potassic and clay overprinting, and stockwork vein development.
- 427.7m to 468.2m: diorite with disseminated sulphides and notable potassic alteration and sporadic mineralized quartz-chlorite veinlets.
Feni Island on-trend location
The Adyton projects are located in PNG on easily accessible island locations. Feni Island is part of the Tabar to Feni Island chain to the Northwest that hosts the operating gold mines of Simbiri and Lihir, while Feni hosts a foundation resource of inferred 1.45moz Au. To the southeast of Feni on Bougainville Island lies the giant Panguna deposit.
