Aeonian expands Koocanusa project

Mr. Andy Randell reports AEONIAN RESOURCES EXPANDS KOOCANUSA COPPER PROJECT ALONG 50 KM FERTILE CORRIDOR FOLLOWING GEOPHYSICAL SURVEY RESULTS Aeonian Resources Ltd. has expanded its 100-per-cent-owned Koocanusa copper project in southeastern British Columbia through the acquisition of two new contiguous mineral tenures. The additions build on results from Aeonian's recent airborne geophysical survey, which highlighted multiple high-priority magnetic anomalies along the 50-kilometre copper corridor (see Sept. 10, 2025, news release). The expanded ground strengthens Aeonian's control of very prospective structural and stratigraphic traps within the Purcell basin, the same geological belt that hosts Montana's world-class sediment-hosted copper-silver deposits. Key highlights: District scale growth: Two new claims expand the Koocanusa project footprint to cover key magnetic anomalies and structural corridors outlined in the 2025 airborne geophysical survey. Enhanced target definition: Adds 6.7 km of prospective strike length along the Gilnockie Fold and Jake Anticline, interpreted as major fold-hosted copper traps. Strengthened geological model: Expansion aligns with magnetic-high anomalies that correlate with copper-bearing horizons of the Creston formation, known to host sediment-hosted Cu-Ag (copper-silver) mineralization and analogous to the world-class Revett formation deposits in Montana. Drill-ready momentum: Newly staked ground will be incorporated into Aeonian's upcoming exploration and drill targeting programs. "Expanding our footprint over these newly defined magnetic and structural corridors solidifies our position along one of B.C.'s most prospective yet underexplored copper systems," stated Andy Randell, chief executive officer of Aeonian Resources. "With permits secured and targets clearly emerging, we're well positioned to advance toward our inaugural drill program at Koocanusa." Tenure acquisition Aeonian has successfully acquired two new contiguous mineral tenure applications (tenure 1126059 and tenure 1126060) at its Koocanusa copper project. The acquisitions follow the recently completed airborne geophysical survey that identified several discrete magnetic-high anomalies associated with favourable lithologies and significantly extend the company's ground position in key structural corridors. Tenure 1126059 extends the property to include the interpreted extent of the southern-striking limb of the Gilnockie fold by approximately 3.5 kilometres to the United States border, significantly enhancing coverage of this inferred structural trap. Tenure 1126060 extends the property to include the interpreted extent of the western limb of the Jake anticline/Yahk target by approximately 3.2 kilometres of inferred strike length, further increasing the footprint of this prospective fold-hosted corridor. Both additional claims serve to fully cover interpreted zones where the geophysical survey returned prominent magnetic high responses, which correlates with favourable surface exposures of the Creston formation (known to host sediment-hosted copper mineralization at Koocanusa) and underlying anomalous rock grab and soil copper values. Copper-bearing Creston formation rocks at Koocanusa are directly analogous to the Revett formation in Montana, which hosts several of Hecla Mining's world-class sediment-hosted Cu-Ag deposits, including Rock Creek and Montanore. This newly staked land is now included in Aeonian's future 2026 exploration programs and provides additional avenues for targeting feeder fault and fold hinge traps along this copper-fertile Purcell basin corridor. First nations engagement and regulatory process Under the new mineral staking process in British Columbia, tenures are reserved via the on-line system and then enter a period of consultation with local first nations. Aeonian was able to expedite the tenure approvals by providing advanced information packages, including an archaeological management plan and wildlife management plan, to both the Shuswap Indian Band and the Ktunaxa Nation Council. The company thanks the bands for their co-operation and expedited review of the tenure applications, a reflection of Aeonian's commitment to transparent and respectful indigenous partnerships. Outlook and next steps With the two new tenures now added to the Koocanusa project, Aeonian has incorporated these zones into its upcoming 2026 exploration program. Activities across the project will include detailed follow-up geophysics, surface mapping, geochemical sampling and drill targeting designed to test both fold-hinge and fault-hosted traps supported by the magnetic anomaly framework. The expanded land package further strengthens Aeonian's position in one of the most underexplored sediment-hosted copper systems in British Columbia and provides a clear path toward discovery. Stock option grant The company also announces that its board of directors has approved the grant of an aggregate of 3.2 million incentive stock options to directors, officers, employees and consultants of the company pursuant to its stock option plan. Each option is exercisable to acquire one common share of the company at a price of 10 cents per share for a period of five years, expiring on Oct. 27, 2030. The options are subject to the terms of the company's stock option plan, applicable securities laws and the policies of the TSX Venture Exchange. All shares issued upon exercise of the options will be subject to a four-month hold period from the date of grant.

Aeonian Resources is a Canadian mineral exploration company focused on discovering the next generation of sustainable mineral resources in British Columbia. Its flagship Koocanusa copper project lies within the Purcell basin, part of the same geological belt that hosts major sediment-hosted copper deposits across the border in Montana. Aeonian has outlined a 50-kilometre fertile corridor with multiple drill-ready targets supported by strong geochemical and geophysical data. With multiyear permits, strong indigenous partnerships and a disciplined, science-driven approach, Aeonian is well positioned for near-term copper discovery in a Tier 1 jurisdiction.
