Aeonian Completes First Drill Hole at Jake Target, Koocanusa Project; Confirms Key Geological Features Consistent With Sediment-Hosted Copper Model

Aeonian Completes First Drill Hole at Jake Target, Koocanusa Project;

Confirms Key Geological Features Consistent With Sediment-Hosted

Copper Model

VANCOUVER, BC / ACCESS Newswire / March 31, 2026 / Aeonian Resources Corp. ("Aeonian" or the

"Company") (TSX.V:ALTN) is pleased to announce that it has completed the first diamond drill hole of its

2026 exploration program at the Jake Target within the Company's Koocanusa Project, located in

southeastern British Columbia.

Highlights

 First drill hole at Jake successfully intersected redox features, copper mineralization, and

sulphides consistent with the Company's sediment-hosted copper exploration model.

 Mineralization and alteration broadly align with modeled Induced Polarization (IP) chargeability

anomaly, supporting geophysical targeting approach.

 Pending assays results will guide follow-up drilling at Jake and additional targets across the district

scale Koocanusa Project.

 Drilling temporarily paused due to seasonal conditions, with the program expected to resume

following spring break-up; the Company will update the market on drill rig remobilization timing

once confirmed.

"The first drill hole at Jake has successfully confirmed that we are operating within a mineralized

sedimentary system consistent with our exploration model, " said Andy Randell, CEO of Aeonian

Resources. "The presence of redox features, copper oxide mineralization, and disseminated sulphides,

along with their association with modeled chargeability anomalies, provides important validation of our

targeting approach. While assays are pending, these early observations are encouraging and support

continued advanced exploration works at Koocanusa. "

The inaugural drill hole was designed to test a chargeability and geochemical anomaly identified through

ground-based IP geophysical surveys, prospecting and sampling, coincident with interpreted structural

features (see March 16, 2026, news release). The hole successfully intersected a sequence of

sedimentary rocks consistent with the targeted stratigraphy and encountered multiple zones of

alteration, structure, and visible copper mineralization.

Drill Hole Summary

Geological logging of the drill core identified several features considered relevant to sediment-hosted

copper systems, including those analogous to the Revett Formation in Montana and Idaho (observations

only; assays pending):

 Redox Features: A distinct oxidation front was observed within the upper portion of the hole,

characterized by changes in colour and mineralogy consistent with redox boundaries known to

control copper deposition in sediment-hosted systems.

 Copper Oxide Mineralization: Green copper oxide mineralization, interpreted as malachite, was

observed at multiple intervals within the drill hole, typically associated with fracture surfaces and

permeable zones. The presence of malachite is considered indicative of copper-bearing fluids

within the system; however, assay results are required to confirm copper concentrations.

 Dendritic Oxide Mineralization: Multiple intervals contain dendritic mineral growths along

fracture planes and bedding surfaces, interpreted to represent oxide mineralization (potentially

manganese and/or copper oxides) associated with fluid movement through permeable

sedimentary units.

 Sulphide Mineralization: Disseminated sulphide mineralization was observed at depth, including

fine-grained ("fly-speck") sulphides and localized zones exhibiting textures consistent with

replacement of the host rock.

 Structural Features: Several fault and fracture zones were logged throughout the hole, including

intervals with vein and fracture-fill mineralization, interpreted to represent pathways for basin-

derived fluids.

 Alteration: The core exhibits variable bleaching and localized silicification consistent with fluid-

rock interaction within permeable stratigraphic horizons.

These features are consistent with the necessary elements and attributes associated with sediment-

hosted copper systems, where metal-bearing basinal fluids migrate through permeable strata and

precipitate sulphide minerals at redox boundaries.

Geophysical Correlation

The drill hole intersected geological features, including disseminated sulphides and structurally

controlled zones, at depths corresponding broadly with a modeled chargeability anomaly identified in

prior IP geophysical surveys.

Chargeability anomalies are commonly associated with the presence of disseminated sulphide minerals

due to their ability to temporarily retain electrical charge. The spatial association between observed

sulphide mineralization and the modeled anomaly provides encouragement that the geophysical

response may be eƯectively identifying zones of sulphide development within the system.

While further drilling is required to confirm the extent and continuity of this relationship, these initial

results suggest that chargeability surveys may represent an eƯective targeting tool for identifying

prospective zones within the Koocanusa Project.

Analytical Work and XRF Screening

All drill core samples from the first hole have been submitted to ALS Canada Ltd. for preparation and

analysis. Analytical results are pending and will be released once received, validated, and interpreted.

The Company is also conducting portable X-ray fluorescence (pXRF) analysis on select intervals of drill

core, which will provide eƯiciency benefits with future geological interpretation and vectoring. pXRF

results are considered preliminary and are not a substitute for laboratory assays; accordingly, they are

not being reported at this time.

Next Steps

The Company is currently compiling and integrating geological, structural, and geophysical data from this

important first drill hole, allowing the exploration team to refine their targeting approach for subsequent

near-term drilling at the Jake Target and across the broader Koocanusa Project.

Drilling activities have been temporarily paused to comply with seasonal road restrictions associated

with spring break-up conditions. The Company anticipates resuming operations once access conditions

improve and will provide an update on the timing of drill rig remobilization to site once confirmed.

About the Koocanusa Project

The Koocanusa Project is a district-scale copper-silver exploration property located in southeastern

British Columbia near the Canada-United States border. The project covers approximately 352 km² of

prospective ground within the Purcell Basin, a large Proterozoic sedimentary basin known to host

stratiform copper-silver mineralization.

Exploration at Koocanusa has focused on identifying conductive stratigraphic horizons and structural

trap zones within Revett-equivalent sedimentary units that may host sediment-hosted copper

mineralization.

The Koocanusa Project benefits from excellent infrastructure and access, including highway access on

three sides of the property and the ability to conduct exploration activities throughout the year.

The current exploration permit allows for drilling activities over a three-year period, providing the

Company with flexibility to advance exploration depending on results.
