How Trigg Minerals Plans to Revive US Antimony Supply with $12.5M Boost

Strategic Acquisition in a Top Mining Jurisdiction

Trigg Minerals Limited has taken a decisive step forward in its ambition to become a leading antimony producer by acquiring 49 unpatented lode mining claims covering the Antimony Canyon Project (ACP) in Utah, USA. Situated in what is widely regarded as the world’s top-ranked mining investment jurisdiction, this acquisition significantly broadens Trigg’s footprint in a critical mineral essential for various industrial and defense applications.

The Antimony Canyon area hosts several historically productive high-grade mines, including the Emma, Mammoth, and Nevada mines, with antimony grades averaging between 1.5% and 2.2%, and some zones reaching as high as 3.6%. Recent fieldwork has confirmed extensive zones of massive stibnite mineralisation, expanding the potential beyond previously defined limits and suggesting a vertically and laterally continuous mineralised system.

Defining a Significant Exploration Target

Building on historical data and recent sampling, Trigg has defined an Exploration Target for ACP ranging from 12.8 to 15.6 million tonnes at 0.75% to 1.5% antimony, equating to an estimated 96,000 to 234,000 tonnes of contained antimony metal. While this target remains conceptual pending further drilling and resource estimation, it underscores the project's considerable scale and potential.

To advance this, Trigg has engaged Dahrouge Geological Consulting to undertake detailed geological mapping, ground truthing, and resource estimation compliant with both Australian JORC and US SEC S-K 1300 reporting standards. Complementing this, geophysical surveys are underway to refine drill targets, with a maiden Mineral Resource estimate anticipated later this year.

Innovative Processing and Environmental Commitment

In parallel with exploration, Trigg has commissioned Metso, a global leader in mineral processing, to conduct a conceptual study on processing antimony concentrates using the Ausmelt Top Submerged Lance (TSL) smelting technology. This advanced pyrometallurgical method promises high metal recoveries, energy efficiency, and significantly reduced greenhouse gas emissions, aligning with Trigg’s commitment to environmentally responsible mining.

The study aims to establish a pilot-scale smelter capable of producing 3,000 to 5,000 tonnes per annum of 99.65% pure antimony ingots, positioning Trigg to supply high-purity antimony to critical markets, including the US defense sector.

Strengthening Leadership and US Government Engagement

Trigg has bolstered its leadership team with the appointment of Andre Booyzen as Managing Director, bringing over two decades of antimony mining and operational expertise. Additionally, the company has added David J. Fourie as Net Zero Expert Antimony Technical Advisor and Ben Harris as US Defense and Armaments Advisor, enhancing its technical and strategic capabilities.

Recognising the strategic importance of domestic antimony supply, Trigg has engaged The Bernhardt Group, a Washington D.C.-based consultancy with deep US government ties, to facilitate engagement with key stakeholders and secure support for the Antimony Canyon Project within US defense and economic frameworks.

Financial Position and Outlook

Trigg closed the quarter with a cash balance of A$3.35 million and successfully raised an additional A$12.5 million through a placement to institutional investors. This capital injection will underpin ongoing exploration, resource definition, and early-stage development activities at ACP and its Australian assets, including the Wild Cattle Creek deposit.

With no production activities during the quarter, Trigg remains focused on advancing its projects towards pilot mining and processing, aiming to fill a critical gap in the US antimony supply chain, which currently lacks domestic production.
