AEONIAN Completes Drilling at Jake Target and Advances District-Scale Copper-Silver Model, Koocanusa Project, BC

Executive Summary

• Aeonian Resources Corp. completed five drill holes totaling approximately 1,229 metres at the Jake Target on its 100%-owned Koocanusa Project in southeastern British Columbia.
• All drill core has been logged, sampled, and submitted to ALS Canada Ltd. for analysis, with assay results currently pending.
• Geological observations and structural reinterpretation have expanded the exploration model from a localized fold target to a broader, laterally extensive stratigraphic corridor, significantly increasing the district-scale exploration footprint.

Key Details

• Drilling Program: Five holes completed at the Jake Target (~1,229m total); includes KOO26-01 (March 2026) plus four new holes (KOO26-02 to KOO26-05) designed to evaluate the continuity and geometry of the Revett-style copper-silver system.
• Core & Assays: All core logged, sampled, and submitted to ALS Canada Ltd.; drill core assays, surface rock samples, and soil geochemistry results are pending and will refine future targets.
• Project Scale: Koocanusa Project covers ~360 km² in the Purcell Basin; Jake Target is located within a 50 km anomalous copper trend on the western side.
• Geological Model Refinement: Interpretation shifted from a localized fold closure to a regionally extensive east-dipping stratigraphic package, emphasizing laterally extensive corridors and fluid conduits over isolated targets.
• Structural & Alteration Observations: Multiple fault zones, breccias, altered gouges, widespread alteration, bleaching, oxidation features, and sulphide replacement textures identified, highlighting structural pathways for copper-bearing fluids.
• Comparative Systems: Model aligns with Revett-hosted sedimentary copper-silver systems in northwestern Montana, including the Troy, Spar Lake, Libby, and Montanore deposits.
• Drill Hole Data: Coordinates, elevations, dip, azimuth, and end-of-hole depths provided for KOO26-01 through KOO26-05 (WGS84 Zone 11N).
• Exploration Permit: Current permit allows for drilling activities over a three-year period.
• Qualified Person: Andrew Randell, P.Geo., reviewed and approved all scientific and technical information per NI 43-101.

Notable Quotes

• Andrew Randell, CEO: "The most important outcome of the 2026 drilling program so far is the increasing alignment between our geological observations and the sediment-hosted copper-silver model that has guided exploration at Koocanusa from the outset... While assays remain pending, the geological evidence collected to date continues to increase our confidence in both the exploration model and the broader potential of the Koocanusa Project."
