Investor Insight
Trigg Minerals is well-positioned to become a globally significant supplier of antimony, a critical mineral essential to the defense, clean energy and semiconductor sectors. Backed by a strategic focus, a supportive jurisdiction, and timing that aligns with macroeconomic urgency, Trigg is uniquely placed to deliver value from the ground up.
Overview
Trigg Minerals (ASX:TMG,OTCQB:TMGLF) is an emerging leader in the global critical minerals space, focused exclusively on the development of antimony—a metal designated as essential by the United States, Australia and the European Union for its role in national defense, energy transition technologies, and advanced industrial applications. The company’s flagship asset, the Wild Cattle Creek deposit within the Achilles antimony project in New South Wales, is the highest-grade undeveloped antimony resource in Australia and one of the few large-scale, standalone antimony projects globally. As geopolitical and industrial dynamics shift, Trigg Minerals is uniquely positioned to provide a secure, sovereign source of antimony to Western markets, amid a continuing global supply crunch.
In 2024, China—responsible for 83 percent of global production—imposed a complete export ban on antimony products to the US, following earlier restrictions on powdered forms. Combined with sanctions on Russian producers and the depletion of strategic stockpiles across NATO and allied nations, these developments have triggered a severe global supply shortage. Spot prices have surged to over US$51,000 per tonne—more than double their 2023 average—underscoring the urgent need for alternative sources.
Antimony spans a wide range of applications. It is a critical component in flame retardants, semiconductors, night vision optics, military alloys, solar panel coatings, and battery technologies. Demand is accelerating, particularly in the defense and renewable energy sectors, with a projected CAGR of 6.1 percent. However, viable new supply is extremely limited outside of China and its allies, presenting a once-in-a-generation opportunity for companies like Trigg to fill the gap and anchor Western critical mineral supply chains.
Trigg’s growth strategy is built around three key points. First, the company is advancing a high-impact resource expansion program at Wild Cattle Creek, aiming to increase its current JORC-compliant resource of 1.52 million tons (Mt) @ 1.97 percent antimony for 29,902 tonnes contained metal to more than 100,000 tonnes—potentially making it one of the top three antimony deposits in the world. Second, Trigg is capitalizing on the structural shift in global supply chains. With a Tier-1 jurisdiction, ESG-aligned operations, and backing from government incentives, the company is ideally placed to serve downstream processors and strategic buyers, particularly in the U.S. and allied nations seeking to reduce reliance on Chinese-controlled supply. Third, Trigg is maintaining disciplined and focused execution. Over 90 percent of capital and operational resources are allocated to advancing Wild Cattle Creek, ensuring near-term value creation.
Company Highlights
- Trigg Minerals is an ASX-listed company entirely focused on antimony, a critical mineral vital for solar panels, flame retardants, semiconductors and military applications.
- The flagship Achilles project’s Wild Cattle Creek deposit hosts a high-grade JORC resource of 1.52 Mt @ 1.97 percent antimony for ~30,000 tonnes contained antimony—Australia’s highest-grade undeveloped antimony deposit.
- The company’s aggressive expansion plan includes a near-term drilling program targeting a threefold increase in contained antimony to over 100,000 tonnes, positioning Trigg among the top three antimony deposits globally.
- Trigg is attracting growing attention as a potential partner to support Western antimony supply chains amid rising demand and geopolitical tension.
- Operating in New South Wales—a Tier 1 jurisdiction—Trigg benefits from government incentives, including co-investment, exploration support and deferred royalty schemes.
- China controls 83 percent of global antimony production and recently banned exports to the US, creating a strategic opening for Western suppliers like Trigg.
Key Project
Achilles Antimony Project – Wild Cattle Creek Deposit
Trigg Minerals’ flagship asset is the Wild Cattle Creek (WCC) deposit, located within its Achilles antimony project in northern New South Wales. Hosting a JORC 2012-compliant mineral resource of 1.52 Mt @ 1.97 percent antimony for 29,902 tonnes of contained metal, WCC is Australia’s highest-grade undeveloped antimony resource and among the most significant globally. The deposit lies along the Bielsdown Fault, a 6 km underexplored mineralised corridor within the New England Orogen—a prolific metallogenic belt.
Geologically, the deposit is hosted in a steeply dipping, silicified breccia lode bounded by metasedimentary rocks. The high-grade core (>2 percent antimony) extends 350 metres down plunge, is exposed at surface, and maintains an average true width of ~20 metres—ideal for future underground bulk mining. The current mineral resource estimate is conservative, focused on cemented breccia zones, but upcoming drilling will include the broader tungsten-antimony stockwork and disseminated stibnite-bearing mineralisation, potentially widening the mining envelope to more than 15 metres. The system is also enriched in tungsten, mercury and gold, with 30 regional gas and geochemical targets identified. Historic hits such as 1.3 m @ 11.8 percent antimony at the Jezebel prospect underscore the broader potential.
Trigg’s near-term strategy is simple and high-impact: secure land access, initiate an aggressive drilling program, and grow the antimony resource to more than 100,000 tonnes. Drilling contracts are in place, target zones have been defined, and land access negotiations are nearing completion, with execution anticipated in mid-2025. With China’s dominance being actively challenged by the West, Trigg offers timely, scalable exposure to a critical mineral that is scarce in nature and increasingly strategic.
Other Projects
Taylors Arm Antimony Project
Taylors Arm is a high-grade antimony district with more than 80 historic workings across seven known mining camps. Samples have returned grades of more than 50 percent antimony, including 63 percent at the Testers Mine—the highest antimony assay on record in Australia. The project also hosts silver grades more than 840 grams per ton (g/t0 and gold up to 24 g/t, indicating a polymetallic system with strong exploration upside. Trigg is conducting early-stage work to refine targets for follow-up drilling.
Spartan Antimony Project
Located adjacent to the Hillgrove antimony-gold operation (Australia’s largest known antimony deposit), Spartan is strategically situated along the Hillgrove Fault and shares geological characteristics with the adjoining high-grade system. Early exploration has confirmed structural continuity and polymetallic potential, particularly for stibnite-gold veining. Spartan complements Trigg’s core project with near-mine growth opportunities.
New Project Areas – Nundle, Upper Hunter, Cobark/Copeland
Trigg recently secured new exploration tenements across the Nundle, Upper Hunter, and Cobark/Copeland regions, all highly prospective for gold-antimony mineralisation. These projects, located within structurally complex terrains analogous to Achilles, will be progressively advanced as part of Trigg’s long-term project pipeline strategy.
