Aeonian Resources begins drilling at Koocanusa

Executive Summary

• Aeonian Resources Corp. has commenced its inaugural 2026 diamond drill program at the Jake Zone of its Koocanusa Copper-Silver Project in southeastern British Columbia.
• The program will drill three holes (~900m total) to test a 130-metre-thick conductive sedimentary package for downdip copper-silver mineralization.
• The target is supported by surface sampling up to 0.32% Cu and 31.1 g/t Ag, strong airborne magnetic/ground conductivity anomalies, and favorable geological bedding orientations.

Key Details

• Drill Program: Inaugural 2026 diamond drill program at the Jake Zone, Koocanusa project.
• Scope: 3 diamond drill holes from 2 drill pads, totaling approximately 900 metres.
• Target Geology: 130-metre-thick conductive sedimentary package interpreted as a premium host for copper mineralization, dipping eastward consistent with surface outcrop measurements.
• Geophysical Anomalies: Conductivity anomaly extends along ~500 metres of strike length and remains open laterally and downdip. Coincident with surface exposed copper-silver mineralization and airborne magnetic geophysics.
• Surface Sampling: Values up to 0.32% copper and 31.1 g/t silver from mineralized sedimentary units exposed at surface (referenced from Dec. 8, 2025 release).
• On-Site Analysis: Portable XRF (pXRF) analyzer will be used on-site to rapidly assess copper concentrations in drill core for real-time geological interpretation and drilling guidance.
• Exploration Pipeline: Jake is 1 of ~19 priority copper-silver targets identified across the district-scale Koocanusa property (~352 km² within the Purcell basin).
• Geological Model: Focuses on Revett-type sedimentary copper mineralization (equivalent to the Creston formation in BC). References regional stratigraphic parallels and deposits like Libby (Montanore), Rock Creek, and Spar Lake for geological context.
• Permit & Timeline: Current exploration permit allows drilling activities over a three-year period. Follow-up drilling decisions will be made after evaluating initial geological observations and laboratory assay results.

Notable Quotes

• "Commencing our inaugural drill program at Koocanusa is an important milestone for Aeonian. The Jake target presents a compelling combination of encouraging copper-silver values at surface, favourable sedimentary host rocks and a strong conductive geophysical signature that may represent sulphide-bearing horizons at depth." – Andy Randell, CEO
• "This program represents the first test of a broader exploration model across the Koocanusa property. With 19 priority targets identified to date, we believe the project has the potential to develop into a significant copper-silver exploration district within the Purcell basin." – Andy Randell, CEO
• "Our objective with this initial drilling is to confirm the geological model and determine whether these conductive sedimentary horizons host copper mineralization at depth." – Andy Randell, CEO
