Trigg Minerals (ASX:TMG) stakes a claim on America’s antimony revival

With much of the critical minerals conversation dominated by lithium and rare earths, Trigg Minerals (ASX:TMG) is charting a different course one that leads deep into the canyons of Utah and towards a commodity the United States doesn’t produce domestically: antimony.

Antimony may be lesser known, but it plays an outsized role in the production of flame retardants, ammunition, semiconductors and battery alloys.

With China and Russia controlling the lion’s share of global supply, Trigg’s Antimony Canyon Project (ACP) is gaining serious attention, not least because of its historical significance and shallow, surface exposed mineralisation ready for low cost evaluation.

Key Highlights

🔹 Trigg is advancing pilot scale mining at ACP, aiming to feed feasibility and processing studies
🔹 Mineralisation extends across a newly defined 10 kilometre corridor, linking Antimony Canyon with Dry Wash Canyon
🔹 Over 250 samples collected for assay; new claims staked to consolidate and expand strategic control
🔹 The project has a foreign resource estimate of 12.7Mt at 0.79% antimony, with over 100,000 tonnes of contained metal
🔹 Strategic interest received, including proposals to uplist to NASDAQ/NYSE

ACP sits in the aptly named town of Antimony a place with historical roots in war-era mining and a name change to match.

Yet, the geology might prove even more enduring.

Fieldwork has revealed stibnite bearing outcrops throughout the Flagstaff Formation, extending both laterally and vertically, indicating system wide continuity not previously captured in resource estimates.

“The confirmation of antimony mineralisation outside our known resource, particularly at Dry Wash Canyon, and the emerging understanding of these controlling North–South structures, is a game changer for the Antimony Canyon Project,” said Trigg Managing Director Andre Booyzen.

“This strategic expansion of our landholding underscores our commitment to establishing a robust presence in the critical minerals sector and positions Trigg Minerals to contribute significantly to America’s future antimony production landscape.”

Adding further depth to the story is Trigg’s plan to initiate surface-based pilot mining.

Using mechanical methods, the company will crush and upgrade ore on site through gravity separation.

It’s a pragmatic approach intended not for early cash flow but to validate metallurgy and streamline downstream studies.

Interestingly, waste dumps from historical operations also contain appreciable antimony, representing an unconventional but accessible source of near term material.

Combined with the recently confirmed mineralisation 10 kilometres north at Dry Wash Canyon, Trigg is now working with a vastly expanded canvas.

While a JORC compliant resource remains a priority, the company is also eyeing a future beyond Australia’s borders.

The suggestion of a US exchange listing hints at a longer term strategy that aligns neatly with Washington’s goal of rebuilding sovereign supply chains for strategic metals.

In a market where first movers matter, Trigg’s presence in Utah could prove timely.

The company is positioning itself not just as an explorer, but as a foundational player in the next phase of America’s critical minerals independence.
