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.

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.

Exploration Target at Golden Crown to Focus on Resource Growth
Highlights
- WIN has defined an Exploration Target for Golden Crown of 400kt to 700kt tonnes between 2.4g/t to 3.2g/t Au for 23,000oz to 73,000oz of gold. This is in addition to the current Inferred Mineral Resource Estimate (MRE) of 400kt @ 3.1g/t Au for 38,000oz of gold1
- The Exploration Target is supported by the successful 2024 drilling campaign, which tested mineralisation below current Inferred Resource at Golden Crown including2:
- 24BCRC014 - 6m @ 10.85g/t Au (140m below MRE)
- 24BCRC012 - 5m @ 3.63g/t Au (95m below MRE)
- WIN remains focused on growing shareholder value through low-cost, high-impact drilling at the high-grade Golden Crown, complementing the recently announced 2025 Butchers Creek MRE update of 5.23Mt at 1.G1g/t Au for 321,000oz of gold
- Heritage clearance results for the 2025 field program have now been received with no impediments to proposed drilling activities
- Preparation work is underway to support a G,000m drilling program, with drilling scheduled to commence in July 2025
The potential quantity and grade of the Exploration Target is conceptual in nature and, as such, there has been insufficient exploration drilling conducted to estimate a Mineral Resource. At this stage it is uncertain if further exploration drilling will result in the estimation of a Mineral Resource. The Exploration Target has been prepared in accordance with the JORC Code (2012). This exploration target is exclusive of the 2021 Golden Crown Mineral resource estimate of 400kt at 3.10g/t Au for 38,000oz of gold.
Gold Project (“BCGP”) located in the East Kimberley region of Western Australia. The BCGP currently contains a global Mineral Resource of 5.63Mt @ 1.98g/t Au for 359,000oz of gold.
The Golden Crown Exploration Target, which lies below the current Inferred Resource, is estimated at between 400kt to 700kt @ 2.4g/t to 3.2g/t Au, representing an additional 23,000oz to 73,000oz of gold beyond the current MRE.
WIN Metals Managing Director and CEO, Mr Steve Norregaard, commented:
“The establishment of an Exploration Target at the high-grade Golden Crown gold deposit following our highly successful 4-hole drilling program late in 2024 marks another important milestone in WIN’s strategy to unlock value from the project. The potential for additional gold at Golden Crown represents a compelling resource growth opportunity that could see Golden Crown be a meaningful satellite producer complementing the main Butchers Creek body of mineralisation.
With a very targeted, low-cost exploration approach this supports our vision of becoming the next gold producer in Kimberley region of WA. The upcoming S,000m drill campaign is designed to test the potential and deliver further value to shareholders through disciplined, high-impact exploration. We’re suitably enthused by what lies ahead.”
Exploration Target Basis
During WIN’s 2024 drilling campaign, 4 holes for 873m were drilled at Golden Crown demonstrating the resource growth potential. In aggregate, 159 holes for 12,570m have been drilled at Golden Crown along the lightly tested 2km strike.
Highlights from WIN’s drilling included:
- 6m @ 10.85g/t Au from 253m in hole 24BCRC014 (140m below the Mineral Resource)
- 5m @ 3.63g/t Au from 222m in hole 24BCRC012 (95m below Mineral Resource)
- 2m @ 6.00g/t Au from 130m in hole 24BCRC013 (25m below Mineral Resource)
The Golden Crown Exploration Target was generated using the following parameters:
- Mineralised envelopes have been remodelled at Golden Crown using Micromine software, with the new intercepts included at Golden Crown North from all holes drilled at the deposit
- A 0.3g/t Au cut-off was applied to constrain the mineralisation envelopes
- Mineralisation envelopes have been extended up to 250m below surface (130m RL) and extended a maximum of 60m radii along strike from a mineralised intercept
- Volume of the mineralisation envelopes were converted to tonnage using a factor of 2.71t per cubic meter, consistent with the April 2025 MRE update for Butchers Creek
- Upper and lower grade ranges were calculated at ±15% of the current MRE for Golden Crown of 3.10g/t Au. The southern extension mineralisation envelope, which was not modelled nor reported in 2021 MRE, has been assigned the average composite grade
- Upper and lower tonnage ranges were calculated at ±15% of the updated mineralisation envelopes
- The Exploration Target output range was rounded to the nearest 1,000oz to reflect the conceptual nature of this calculation

Heritage Clearance for 2025 Drilling Programme
All drilling proposed in the 2025 heritage survey has been approved by the Koongie Elvire Traditional Owners Group following the completion of a heritage survey in April. This approval enables WIN to accelerate its 2025 drilling programme, focusing on growing the Golden Crown resource and testing the EIS co-funded exploration target, Ganymede3.
Future Work
The 2025 field season has commenced with reconnaissance work underway, now both heritage survey and the necessary clearances have been received. The drilling program will primarily focus on resource growth at the Golden Crown gold deposit, with 9,000m of drilling planned to commence in June/July 2025. An updated MRE for Golden Crown is expected later in 2025.
Location and Project History
The Golden Crown gold deposit is within exploration licence E80/4976, which is 4.5km north of the Butchers Creek gold mine and 30km southeast of Halls Creek in the Kimberley region of Western Australia. The project is accessible via the Duncan Road that connects the BCGP to the town of Halls Creek and the Great Northern Highway.
