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.
