Equinox Resources: high-grade antimony at Alturas

Rock chip samples from Equinox Resources (ASX: EQN) Alturas antimony project in British Columbia, Canada, have returned ultra-high-grade assays, notably 69.98% antimony.

The company has increased its total land holding interests to 6.31km² on the Alturas project. Historically, 105t of antimony ore, averaging 57.20% antimony has been sold from the Alps-Alturas antimony mine on this property.

Since the execution of the option agreement for the Alturas project, the price for antimony has reached $54,000 (US$36,000) per metric ton as of October 25, 2024, from about $36,000 (US$24,000) per metric ton at the time of acquisition. This significant price increase has been driven by supply constraints arising from new export controls on antimony announced by China in September 2024.

Equinox Resources managing director Zac Komur says the company is thrilled to announce its latest exceptional exploration results, revealing extraordinary antimony assays that highlight the immense potential of the Alturas project.

“Rock chip samples have returned grades as high as 69.98% antimony, establishing some of the world’s highest reported natural stibnite grades,” he said.

“Considering that pure stibnite contains 71.4% antimony, these findings confirm Alturas as a truly unique and valuable asset.

“By strategically expanding our footprint with additional claims to the east and west, we are positioned to explore beyond the known mineralisation.

“The discovered copper zone, with rock chips grading at 0.96% copper, along with an extensive shear system, further solidifies Alturas as an outstanding opportunity.

“This project offers us a rare chance to unlock substantial value by systematically exploring an underexplored, ultra-high-grade asset in a mining-friendly jurisdiction.”

Drilling is underway at Equinox’s Mata da Corda titanium and Campo Grande rare earth projects in Brazil, with assays pending.
