Advancing a district-scale
copper system in southeastern BC
Aeonian Resources Corp. is unlocking Canada’s next great sedimentary copper district at its 100%-owned Koocanusa Copper Project in the Purcell Basin, British Columbia.
From a collection of copper occurrences into a well-defined district-scale mineral system
Aeonian Resources Corp. (TSX.V: ALTN) is a founder-led exploration company advancing its 100%-owned Koocanusa Copper Project in the Purcell Basin of southeastern British Columbia, a Tier 1 mining-friendly jurisdiction.
Koocanusa is evolving from a series of individual copper showings into a well-defined, district-scale sediment-hosted copper system — confirmed by the Company’s first drill program and a decade-scale program of mapping, sampling and geophysics.
In 2026, a five-hole drill programme at the Jake target, on the project’s western copper corridor, provided the first substantive subsurface test of the corridor, confirming that copper-bearing Revett-equivalent quartzites continue at depth.

Koocanusa Copper Project
The project sits in the Purcell Basin, 30 to 45 minutes south of Cranbrook, British Columbia, on road-accessible ground with established infrastructure. Copper and silver occur in permeable quartzites and sandstones of the Creston and Sheppard formations — the Canadian continuation of the stratigraphy that hosts Rock Creek and Montanore in northwest Montana.
Ninety-eight copper occurrence sites along the western corridor
A vertically stacked exploration system spanning approximately 50 kilometres. Beyond the western trend, an emerging eastern corridor — including the Lilo and Frankie showings — remains a high-potential extension of the same regional system.
Drilled — 2026, five holes
Jake
First systematic subsurface test of the western copper corridor. Copper-bearing Revett-equivalent quartzites confirmed from surface into the subsurface, with two distinct mineralised bands intersected.
98 copper occurrence sites are classified along the western corridor: 2 drilled, 46 sampled, 50 prospected and unsampled.
Unlocking Canada’s next great sedimentary copper district
A tight share structure, a drill-ready project and a founder-led technical team.
Where rocks meet reason
Understanding the geology is understanding the opportunity. The Learning Centre sets out the science behind Koocanusa, from the Purcell Basin copper beds to the rocks that host the copper, so the story can be judged on its evidence.
Our commitment to sustainability
At Aeonian Resources, sustainability is not an afterthought — it is fundamental to how we explore, operate, and grow. We are committed to advancing mineral exploration in a way that respects the environment, supports local communities, and upholds transparency and accountability throughout the exploration lifecycle.
