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

February 4, 2025 Off By MarketOpen

In a market where critical minerals are increasingly taking centre stage, Trigg Minerals (ASX:TMG) is making a strategic play for antimony – a metal that is both indispensable and largely overlooked in Australia’s resource sector.

With the acquisition of the past-producing Bukkulla Mine and an extension to the historically significant Nundle Goldfield, Trigg Minerals is expanding its footprint in New South Wales, bringing new life to a commodity that has long been overshadowed by gold and lithium.

The Case for Antimony

Antimony is a crucial element in flame retardants, semiconductors, and military applications, yet China dominates the global supply chain.

The metal has been identified as critical by the Australian and US governments, yet domestic production remains limited.

This creates an opportunity for players like Trigg to tap into an underdeveloped yet strategically vital market.

Trigg’s New Ground

With the latest exploration licence applications (ELAs), Trigg’s antimony holdings now cover 1,026km², adding to its already substantial regional portfolio of 717km².

The highlight is the Bukkulla Mine, which historically produced high-grade antimony at over 25% Sb – far exceeding typical mining grades.

Recent rock chip sampling confirmed the site’s potential, returning grades of around 23% Sb.

“This is an exciting step forward for Trigg Minerals as we continue to diversify and grow our exploration footprint in highly prospective regions like the New England Orogen,” said Executive Chairman Tim Morrison. “These new applications demonstrate our commitment to unlocking shareholder value by targeting highly prospective areas with strong potential for further major discoveries.”

Untapped Potential in Nundle Goldfield

Trigg’s expansion also includes the North Nundle Antimony Project, covering an extension of the historically productive Nundle Goldfield.

The area has seen limited modern exploration, but historical workings suggest strong potential for both gold and antimony mineralisation.

Nearby, the Tia Antimony Project covers deep leads and reef gold occurrences, adding further prospectivity.

Geologically, the region shares characteristics with Hillgrove-type deposits, which are known for high-grade antimony-gold mineralisation.

This presents Trigg with a rare opportunity: exploring historically known deposits with modern techniques to unlock new economic resources.

The Road Ahead

Unlike other commodities prone to speculative booms and busts, antimony is largely driven by industrial demand.

With no modern exploration conducted at these tenements, Trigg has a clean slate to execute systematic surveys, geochemical sampling, and drilling campaigns.

While Australia has a long history of gold and base metal exploration, antimony has remained under the radar.

Trigg Minerals’ strategic push into the sector could position it as a leader in domestic antimony supply at a time when Western economies are seeking to diversify away from China’s dominance.

For investors looking beyond lithium and gold, Trigg’s bet on antimony could be a timely and high-grade opportunity.
