Copper Quest Exploration has announced the completion of an arms-length purchase agreement to acquire full possessory rights and interest in the Auxer Gold Property in Bonner County, Idaho, US.

This acquisition expands the company's prospective gold and copper assets across North America.

The property spans 1,087 hectares (ha) and includes 130 unpatented lode claims.

It benefits from road access and proximity to the BNSF Railway mainline, potentially lowering transport costs and accelerating development timelines.

Auxer Gold features a 7km strike length of mineralisation, with geological characteristics similar to orogenic gold settings.

The site contains several high-grade ore shoots, suggesting the possibility of significant underground mining activities.

It includes 1,000m of historical underground workings that offer valuable geological data and possible cost savings through existing access points.

Under the agreement terms, Copper Quest has distributed two million common shares valued at $0.15 each and will pay a non-refundable fee of $30,000 ($40,991) for full possessory rights to the project.

The company has also received permits for surface diamond drilling and re-establishing underground access to historical workings such as the Boston Vein and Chicago Vein systems.

The site shows near-surface high-grade mineralisation, with historical exploration results revealing grades of up to 26.8 grams per tonne (g/t) gold by Lightning Creek Gold.

Additional infrastructure permits allow for temporary road construction and water withdrawal.

Copper Quest president and CEO Brian Thurston said: “The Auxer is just the latest acquisition for Copper Quest and adds to our existing gold portfolio including the past-producing Alpine Gold mine located approximately 150km to the north-west. From a geological perspective, the Auxer Project exhibits all the hallmarks of other mineralised orogenic gold systems as defined by contemporary deposit models.

“The expansion of the Boston Vein from 0.6m at surface to 3.66m at a 20m depth demonstrates classic orogenic gold vein geometry with strong depth continuation potential with mineralisation extending over multiple kilometres.”

In November 2025, Copper Quest announced an arms-length option to purchase agreement to acquire the Alpine Gold mine in British Columbia, Canada, from 0847114 BC (Privco).
