Aeonian Resources completes drill hole at Koocanusa

Executive Summary

• Aeonian Resources completed the first diamond drill hole of its 2026 exploration program at the Jake target on the Koocanusa project in southeastern British Columbia.
• Geological logging confirmed redox features, copper oxide mineralization (malachite), disseminated sulphides, and structural/alteration zones consistent with a sediment-hosted copper model.
• Observed mineralization aligns with modeled IP chargeability anomalies, validating the geophysical targeting approach; assay results are pending and drilling is temporarily paused for spring break-up.

Key Details

• First drill hole successfully intersected a sequence of sedimentary rocks matching targeted stratigraphy, with multiple zones of alteration, structure, and visible copper mineralization.
• Geological observations include: distinct oxidation front (redox boundary), green copper oxide mineralization (malachite) at multiple intervals, dendritic oxide mineralization along fractures/bedding, disseminated sulphides (fine-grained and replacement textures), fault/fracture zones with vein and fracture-fill mineralization, and variable bleaching/silicification.
• Drill hole intercepts correspond broadly with a modeled induced polarization (IP) chargeability anomaly, supporting the use of geophysical surveys to identify sulphide development.
• All core samples submitted to ALS Canada Ltd. for preparation and analysis; laboratory assay results are pending.
• Portable X-ray fluorescence (pXRF) analysis is underway on select intervals for preliminary geological vectoring; results are preliminary and not reported.
• Drilling temporarily paused due to seasonal road restrictions associated with spring break-up; program expected to resume once access conditions improve.
• Next steps involve integrating geological, structural, and geophysical data to refine targeting for subsequent near-term drilling at the Jake target and across the broader district-scale Koocanusa project.
• Project covers approximately 352 square kilometres in the Purcell basin, with a three-year exploration permit allowing for continued drilling and exploration activities.

Notable Quotes

• "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. "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."
