A boost for antimony: Trigg Minerals (ASX:TMG) doubles down at Wild Cattle Creek

A Major Milestone for Trigg Minerals

In a critical juncture for the Australian mining sector, Trigg Minerals (ASX:TMG) has delivered a game-changing update on its flagship Wild Cattle Creek (WCC) antimony deposit in New South Wales.

The newly released Mineral Resource Estimate (MRE) confirms a 92% increase in contained antimony, positioning Trigg Minerals as a pivotal player in the global scramble for critical minerals.

The headline numbers are compelling. With an updated resource of 1.52 million tonnes at 1.97% antimony, containing 29,902 tonnes of the element, Wild Cattle Creek cements its status as the second-largest antimony deposit in NSW.

Trigg’s Executive Chair Timothy Morrison aptly summed up the milestone:

“The near doubling of the Mineral Resource at Wild Cattle Creek is a great achievement for the entire team at Trigg. This substantial upgrade reinforces its status in Trigg’s portfolio and elevates us to a globally significant position in securing antimony supply”.

Antimony’s Critical Role

Antimony, an often-overlooked critical mineral, plays a key role in flame retardants, batteries, and semiconductors.

With geopolitical instability impacting traditional supply chains, securing domestic sources has become an urgent priority.

As Morrison highlighted,

“Achilles underscores our commitment to driving growth and meeting the critical demand for antimony”.

Exploration Upside at Achilles

The Achilles Project, of which WCC is part, is proving a geological goldmine—or rather, an antimony mine.

Located 40 km west of Coffs Harbour, the deposit spans a 6-km structure, largely unexplored beyond a vertical depth of 100 metres.

Trigg’s geologists have identified multiple high-grade zones (>1.6%) that remain open at depth and along strike.

The deposit’s geology is intricate, featuring a complex interplay of hydrothermal breccias and stibnite-rich zones, offering tantalising exploration upside.

Expanding the Resource Horizon

In a bid to maximise its value proposition, Trigg has also laid the groundwork for evaluating additional resources in tungsten and gold.

While not yet included in the current MRE, these elements present significant blue-sky potential.

Moreover, historical metallurgical testing indicates robust recoveries of over 95% antimony, a strong starting point for future feasibility studies.

Data Integrity and Validation

But there is more to the story than resource growth, Trigg has taken the bold step of reconstructing and validating decades-old drilling data.

Early handovers revealed transcription and calculation errors, which the company meticulously corrected.

This effort underscores Trigg’s strategic focus on transparency and quality, an approach that should reassure investors and regulators alike.

Looking Ahead: The Pathway Study

Looking ahead, Trigg plans to leverage geophysics to support a “Pathway Study,” aiming for a 100,000-tonne resource base.

This sets the stage for infill drilling and deeper exploration, as well as targeting additional high-priority zones within the Achilles licence area.

Strategic Implications for Australia

The broader implications are clear: in an era of intensifying demand for critical minerals, Wild Cattle Creek is emerging as a cornerstone project—not just for Trigg Minerals, but for Australia’s strategic mineral security.

With disciplined exploration and a robust growth strategy, Trigg is carving its niche in a market where every tonne of antimony counts.
