Aeonian Reports Final Drill Results from Jake Target and Advances District-Scale Copper Exploration Model at Koocanusa
AEONIAN REPORTS FINAL DRILL RESULTS FROM JAKE TARGET AND ADVANCES
DISTRICT-SCALE COPPER EXPLORATION MODEL AT KOOCANUSA
Vancouver, British Columbia – August 6th, 2026 – Aeonian Resources Corp. (TSX-V: ALTN) ("Aeonian" or
the "Company") is pleased to report final assay results from its inaugural five hole diamond drilling program
at the Jake Target within its 100% owned Koocanusa Copper Project in southeastern British Columbia. The
program comprised 1,229 metres, including four follow up holes totalling 954 metres completed in June
2026 (see Company news release dated June 17, 2026).
The program provided the first subsurface geological information from Koocanusa and confirmed that
prospective Revett-equivalent stratigraphy continues at depth. Although drilling did not identify significant
copper-silver intercepts at the locations tested, localized anomalous metal values, alteration and structural
features have refined the Company’s understanding of the controls on mineralization and establish ed a
calibrated framework for future exploration across its approximately 360 km² land package.
Highlights
• Completed the inaugural 1,229 metre, five-hole diamond drill program at the Jake target,
representing the first subsurface test of the Koocanusa Project.
• Four follow-up holes totalling 954 metres tested interpreted higher-priority portions of Jake
between the surface copper occurrences and the deeper KOO26-01 intersection.
• Confirmed the continuation at depth of prospective Revett-equivalent host rocks and identified
alteration and structural zones interpreted to record hydrothermal fluid movement through the
sedimentary package.
• Demonstrated that structural architecture and hydrothermal fluid pathways are key controls on
copper mineralization.
• Results support the Company's evolving district -scale exploration strategy across 360 km²
containing more than 50 km of prospective stratigraphy.
• Future exploration will focus on applying the refined geological model to provide important criteria
for ranking future targets across the project area.
"The purpose of this first drill program was not simply to test a single target, but to improve our
understanding of an emerging mineral system," said Andy Randell, P.Geo., CEO of Aeonian Resources.
"Although the drilling did not intersect significant copper grades, it successfully achieved its principal
objective by calibrating our geological model. We now have a much clearer understanding of the relationship
between favourable stratigraphy, structural architecture and hydrothermal fluid flow, providi ng a stronger
framework for ranking future drill targets."
"Perhaps most importantly, Jake has evolved from an exploration target into the geological calibration site
for evaluating opportunities across our 360 km² land package. The project is increasingly becoming a
regional exploration story, and the knowledge g ained through these first five holes will guide every future
exploration decision we make."

Drilling Refines Geological Model and Controls on Copper Mineralization
The 2026 drilling program provided the first opportunity to test the subsurface geology at the Jake Target
and refine the Company's exploration model developed through the integration of regional geological
mapping, airborne geophysics, soil geochemistry, structural analysis and surface sampling.

Notes: Reported intervals are drilling length, and the true width of the mineralized intervals has not yet
been determined. Drill hole K0026-01 was previously reported on May 5, 2026.
KOO26-01, completed in March 2026, tested the eastern and deeper portion of the Jake Target and
confirmed the presence of copper-bearing hydrothermal fluids beneath the zone of surface oxidation (see
Company news release dated May 5, 2026). The hole intersected localized structurally controlled quartz -
sulphide veining returning up to 607 parts per million (“ppm”) copper, 77.7 grams per tonne (“g/t”) silver
and 6.11 g/t mercury, providing the first direct evidence that mineralizing fluids had migrated through
favourable Revett-equivalent stratigraphy (Figures 1, 2).
Subsequent drill holes KOO26 -02 through KOO26 -05 (see Company news release dated June 17, 2026)
were designed to evaluate the continuity of the prospective stratigraphy between the surface copper
occurrences and the deeper KOO26-01 intersection, while testing structural settings interpreted as potential
fluid pathways and trap sites for copper-silver mineralization (Figures 1, 2).
Although the drilling did not intersect economic copper grades, the complete assay dataset demonstrates
that copper mineralization is widespread throughout the targeted stratigraphic sequence rather than being
restricted to isolated intervals. Across the five-hole program comprising 944 drill core samples, 71 samples
returned greater than 50 ppm copper, including 39 samples exceeding 100 ppm copper, confirming that
copper-bearing hydrothermal fluids affected the Revett -equivalent host rocks over a broad ver tical extent
(Table 1). Elevated mercury and silver values are concentrated within structurally controlled vein zones,
while anomalous cobalt occurs more broadly throughout the sequence, further supporting the interpretation
of a regionally extensive hydrothermal system.

Drilling also confirmed the continuation of favourable Revett-equivalent sedimentary units beneath surface
at Jake. Widespread bleaching, disseminated sulphides, quartz veining and multiple generations of
hydrothermal alteration observed throughout the cor e demonstrate that the geological processes
responsible for transporting and depositing metals operated across much of the targeted stratigraphy.
Perhaps most significantly, the drilling demonstrated that the distribution of anomalous copper is controlled
by a more complex interaction of favourable stratigraphy, structural architecture and hydrothermal fluid flow
than could be resolved from surface observations alone. Faults, fracture networks and zones of enhanced
permeability were encountered more frequently than anticipated and are now interpreted to represent
important conduits capable of focusing mineralizing fluids into favourable host rocks
Rather than evaluating Jake as an isolated prospect, the Company now considers it the geological reference
point for understanding similar mineralized environments across the broader Koocanusa Project. The
knowledge gained through this inaugural drilling p rogram has substantially refined the Company's
exploration model and will guide future targeting across more than 350 km² of prospective mineral tenure,
where exploration will focus on areas where favourable Revett-equivalent stratigraphy, structural complexity
and evidence of hydrothermal fluid flow coincide.
From Individual Prospect to District-Scale Opportunity
The Jake target was selected for the inaugural drill program based on its surface copper occurrences,
interpreted structural and stratigraphic setting, advanced permitting and infrastructure. Although the
program did not identify significant copper -silver intercepts at the drill locations tested, the geological
information gained at Jake is directly applicable to evaluating other targets across the Koocanusa Project.
Koocanusa comprises approximately 360 km² of mineral tenure covering more than 50 kilometres of
prospective Revett-equivalent stratigraphy. Exploration has identified numerous copper occurrences and
geochemical anomalies across the property, including surface rock samples returning up to 9,832 ppm Cu
at Lilo, 5,654 ppm Cu at Frankie, 5,542 ppm Cu at Yahk East, 3,188 ppm Cu and 31.1 g/t Ag at Jake, and
2,912 ppm Cu at Oke Creek (see Company news release dated December 8, 2025).
Rather than viewing Jake as an isolated target, the Company now considers it the geological calibration site
for evaluating the broader district. The refined exploration model will be applied across the Company's
5
regional land package to prioritize targets where favourable stratigraphy, structural preparation and
hydrothermal fluid pathways coincide.
Next Steps
The Company is now transitioning from initial calibration drilling to regional exploration aimed at refining
and prioritizing future drill targets. Planned work includes completion of regional mapping, soil
geochemistry, portable XRF screening, prospecting , structural analysis across the broader Koocanusa
project area, and integration of geological and geophysical datasets into an updated district-scale exploration
model.
