ADYTON DISCOVERS NEW AU-CU MINERALIZED ZONES AND DOCUMENTS

RESOURCE CONTINUITY

Brisbane, Australia – February 18, 2026 – Adyton Resources Corporation (TSX Venture: ADY) (“Adyton” or the

“Company”) is pleased to announce successful results from its ongoing drill program at the 100% owned Feni

Island Gold-Copper Project, located within the gold-prolific Lihir Island Chain, Papua New Guinea (PNG).

To date, 10,663m of the ongoing drill program have been completed, successfully achieving its objectives: to

confirm high-grade extensions to the north; and to identify significant new scale potential to the south.

KEY HIGHLIGHTS

 High-Grade Northern Expansion: Hole FDD017 returned 1.29g/t Au over 53m, including a high-grade interval

of 3.6g/t Au over 5m with a peak grade of 6.6 g/t Au over 1 m , further defining a northern expansion zone

trending beyond the current resource model. Approximately 35% of gold assays and 100% copper assays

remain pending for the hole;

 Major Southern Scale Potential: Geological logging from the south-southwest (SSW) corridor (Holes FDD019,

FDD021, and FDD028) highlights strong vectors toward expansion of the epithermal gold-copper system and

reinforces links to a potential porphyry source, significantly increasing the system’s prospective footprint;

 Resource De-Risking & Connectivity: Step-out drilling in "The Gap" (Holes FDD004 & FDD005) demonstrates

continuous mineralization linking key zones, while twin drilling (Holes FDD001, FDD002 & FDD026) validates

historical results, advancing confidence toward upgrading inferred resources to indicated; and

 District-Scale Upside: New modelling and reprocessed geophysics define a compelling system-scale

"blueprint" likely linking the Kabang epithermal resource to the deeper Danmagal porphyry target and

unlocking multiple high-priority drill targets.

“Drill hole FDD017 delivered the highest gold grade (peak grade of 6.6 g/t Au) of the current campaign within a broad

highly mineralized interval, providing compelling evidence that the Kabang system remains open to the north and

continues to grow,” said Tim Crossely, CEO. “In addition, integrated interpretive work by Global Ore Discovery,

combined with results from our recent magnetic survey and reprocessed IP data has defined what we believe to be a

key south westerly fluid-flow corridor linking the Kabang epithermal gold system to a deeper porphyry source. This is

a major step forward for the project. It not only strengthens the expansion potential of the existing epithermal

resource but also opens the door to testing a potentially significant porphyry target at depth. We believe we are just

beginning to unlock the full scale of the system.”

NORTHERN EXPANSION: High-Grade Structures Confirmed

Drilling has successfully identified a new mineralized corridor trending north-northeast (NNE), highlighted by assays

from FDD017 and FDD012, as well as visual logging from surrounding later holes (pending assays) FDD018, FDD020,

FDD025. This area represents a high-priority target for resource grade improvement.

 Geology: FDD017 intersected phreatic breccia in monzodiorite and intense K-feldspar-quartz-sericite

alteration overprinting earlier biotite. This distinct alteration assemblage is associated with high-grade

mineralization and is indicative of a robust and widespread hydrothermal system.

 Multi-Element Support: Hole FDD012, also in the NNE corridor, in addition to gold and copper (see Table 1),

returned significant silver and molybdenum values, including: 5m @ 21.16g/t Ag and 7m @ 211ppm Mo

(both from 266m), further validating the presence of a fertile, multi-phase mineralized system in this north-

northeast zone.

SOUTHERN EXPANSION: Expanded Gold-Copper and Vectors Toward Porphyry Source

Drilling to the south-southwest (SSW), specifically holes FDD019, FDD021 and FD028, have opened another major

corridor outside the current MRE block model.

 Geological Visuals: Logging and geochemical zonation in this area show distinct vectors trending southwest

(SW) and to depth—directly towards the Danmagal porphyry target.

 Porphyry Link : Drilling has encountered apophyses of porphyry-style intrusives and related copper

mineralization (qtz-cpy-mt veins, B,C-veins); geochemistry shows a highly anomalous molybdenum halo

(Mo); and recently for the first time recognised at Kabang, centreline quartz-sulphide veins (B-veins) in the

southern drilling at Kabang - all of these support the geological model that the Danmagal porphyry is the

likely driving source of the Kabang epithermal system. This provides confidence of the scale potential of Feni

to host a Tier-1 deposit similar to neighbours in the Lihir Island Chain.

RESOURCE DE-RISKING & CONNECTIVITY

The current drill program continues to feed into our understanding of the resource, and is successfully de-risking the

resource, specifically increasing confidence and geological continuity.

 Closing "The Gap": Holes FDD004 and FDD005 tested a previously undrilled zone between major resource

blocks. Results confirmed continuous mineralization, linking previously disparate zones.

 Data Validation : Twin holes FDD001, FDD002, and FDD026 showed a strong correlation with historical

drilling. This validation will be critical for converting a significant proportion of inferred resources to the

higher-confidence indicated category.

FUTURE CATALYSTS & OUTLOOK

Adyton is well-funded (ca. CA$17m, 100% for Feni Project) and executing a systematic growth strategy. Upcoming

milestones include:

 Pending Assays: Results pending for FDD017 (all Cu and Au to EOH), plus FDD018 and above. Key holes

upcoming:

o NNE: balance of FDD017, plus FDD018, FDD020, FDD023, FDD025

o SSW: FDD019, FDD021, FDD024, FDD026, FDD028.

 Ongoing Drilling: focused on expanding the MRE footprint at Kabang, and testing new targets.

 Advanced Geophysics: A new, high-power (100kVa) IP/MT survey is being scoped to detect additional across

island and deeper drill targets, 20x more powerful than the previous IP only system (and very limited previous

footprint) used at Feni.

 Spectral Mapping: Deployment of pXRF and spectral mineral mapping (1Q 2026) to generate a 3D alteration

model for precise vectoring of future high-grade drilling.

1 Interval widths are “apparent” widths downhole, subject to true width determination.

2 ADK series drilling (2021) reported previously to TSX.V. Au.eq recalculated here.

3 Gold equivalent calculated as: Au.eq = ((Au g/t *0.93) + (Cu% *1.71 * 0.90)). Based on: metal prices of US$2,000/oz Au and

US$5/lb Cu; and recoveries of 93% Au and 90% Cu. Recovery assumptions are speculative as no metallurgical test work have

been completed at Feni but are based on comparable deposits.

Figure 6: 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 is 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.

FERGUSSON ISLAND PROGRESS UPDATE

EVIH our JV partner continues to progress in parallel permitting for the Wapolu mine restart along with purchasing

commitments to long lead items and project logistic solutions. In early February, Adyton Managing Director, Tim

Crossley, and EVIH Project lead, Louis Wang, jointly presented the projects restart plans to the Mineral Resources

Authority (MRA). Adyton and EVIH remain confident that a H2 restart of Wapolu will be achieved.

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 using single-use tie-locks 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 much lesser extent,

also NQ core. Core recovery is considered to be appropriate.
