Trigg Minerals (ASX:TMG) eyes a sharper edge at Wild Cattle Creek

Trigg Minerals (ASX:TMG) has uncovered a buried opportunity at its Wild Cattle Creek antimony project, with high-grade historical assays revealing shallow mineralisation that never made it into its current resource estimate—offering a potential shot in the arm for one of Australia’s most intriguing undeveloped antimony plays.

In a rare move that merges forensic data review with forward-looking strategy, Trigg’s recent deep dive into legacy sampling records has exposed a cache of assays averaging 4.83% antimony (Sb) across 38 samples exceeding 1% Sb.

Critically, these results—once incorporated into a 2012 JORC-compliant estimate by a prior owner—are absent from Trigg’s 2024 restated resource, creating immediate and tangible upside.

Highlights
• Back-sampling from an underground adit returned intercepts such as:
- 5.42m @ 9.6% Sb
- 2m @ 12.7% Sb
- 3.64m @ 7.3% Sb
• Parallel “Roula” lode shows hits of:
- 2m @ 14.45% Sb & 0.84% W, incl. 1m @ 27.6% Sb
• Roula lode averages 13% Sb and 1.03% tungsten, remains open in all directions
• Wild Cattle Creek remains Australia’s highest-grade primary antimony resource:
- 1.52Mt @ 1.97% Sb (Indicated + Inferred)
- With an average mineralised width of 20m—remarkably broad for this style of deposit

It’s not just the numbers that impress—it’s what they represent.

The samples were collected from the back of an adit, a 1960s-era underground tunnel, and confirm both continuity and elevated grade of the mineralisation between drill sections.

This kind of sampling, overlooked in the modern MRE, enhances geological confidence and may be key to unlocking mine design flexibility and early-stage extraction.

Trigg Minerals Managing Director Andre Booyzen was unequivocal:

“The high-grade results strongly validate the continuity and tenor of antimony mineralisation at Wild Cattle Creek. These outcomes reinforce our confidence that substantial high-grade mineralisation remains accessible at shallow depths… and may inform future mine design by highlighting the potential for early, low-cost extraction.”

With antimony classified as a critical mineral by Australia, the US, and Europe, Trigg’s timing may prove fortuitous.

The commodity is essential for flame retardants, semiconductors, and increasingly, in next-gen battery chemistries.

What’s Next
• Update the Wild Cattle Creek resource with previously excluded data
• Evaluate early-stage development scenarios based on accessible high-grade material
• Expand Roula and surrounding lodes through targeted drilling

In a market hungry for domestic critical mineral sources, Trigg may have just unearthed more than just ore—it’s surfaced a second chance to reshape its resource base without a single new drillhole.

That’s a rare alchemy in any exploration narrative.
