Equinox Resources (ASX:EQN) unveils copper and antimony potential at Alturas Project in British Columbia

Equinox Resources (ASX:EQN) has taken a significant leap forward with its exploration at the Alturas Antimony Project in British Columbia, uncovering expansive mineralisation zones that reinforce the potential for both antimony and copper.

The latest campaign has provided compelling evidence of a highly mineralised system, with newly discovered copper-bearing boulders and a previously identified shear zone now extending 1.5 km across the property.

These findings set the stage for future exploration and underscore the geological promise of this historic mining site.

Key Highlights:

• A 1.5 km shear zone was mapped, with widths between 5 and 25 metres, featuring key dilation zones that enhance the potential for further mineralisation.
• Discovery of copper-bearing boulders, with visible malachite staining, estimated to contain 0.5% to 1.5% copper.
• Confirmation of high-grade stibnite mineralisation, with some samples showing up to 90-100% stibnite.

Zac Komur, Managing Director of Equinox Resources, stated, “The latest exploration results at the Alturas project have exceeded our expectations, particularly with the confirmation of the wide, expansive 1.5 km shear zone and the discovery of a new copper-bearing boulder field. These findings, combined with the project’s historical ultra-high-grade antimony mining, reaffirm its potential for both antimony and polymetallic mineralisation.”

The campaign also confirmed the presence of historical workings from the Alps-Alturas Mine, which produced 105 tonnes of high-grade antimony ore, averaging 57.2% Sb, between 1915 and 1926.

Equinox’s team has verified several key geological features in the area, including zones of iron carbonate and talc alteration, which further point to hydrothermal activity conducive to high-grade mineralisation.

Copper Discovery Adds Exploration Upside

Perhaps the most exciting development from the campaign is the discovery of a copper-bearing boulder field, marked by malachite-stained rocks and fine sulphides.

This new zone sits along the east-west shear zone and suggests an untapped copper-rich mineralised system beneath the surface.

The discovery opens a new exploration front for the project, providing further upside potential in addition to the known antimony deposits.

The company’s exploration work included extensive sampling and mapping, with the results from laboratory assays expected in late October to early November.

These will provide critical insights into the grades of antimony, copper, and associated minerals, shaping the future exploration strategy.

Komur adds, “We look forward to receiving the assay results from this exploration campaign, which will further inform our next steps.”

Next Steps:

Equinox plans to expand its sampling along the eastern extension of the shear zone to further delineate the copper and antimony mineralisation.

In addition, the company will conduct geophysical surveys to better understand the structural complexity of the area.

Pending favourable results, future drilling campaigns will target both the high-grade stibnite zones and the newly discovered copper-bearing boulder field, with the goal of unlocking the full mineral potential of the Alturas Project.

Equinox’s Alturas exploration offers a glimpse into a project with significant geological upside, driven by methodical exploration and strategic focus on key mineralisation zones.
