Massive Stibnite Confirmed in Utah

Trigg Minerals Ltd (ASX – TMG) has announced a significant milestone in its maiden exploration campaign at the Antimony Canyon Project (ACP) in Utah, USA. The company’s in-country team has confirmed multiple zones of massive stibnite mineralisation within the Emma and Mammoth deposits, two of the project’s historically high-grade antimony mines. This field validation not only supports historical data but also strengthens the case for the project’s potential to host a substantial and high-quality antimony resource.

Strategic Importance of Antimony Canyon

Located in one of the world’s most mining-friendly jurisdictions, the ACP covers 49 unpatented lode claims and includes over 30 historic antimony mines. Antimony, a critical mineral used in renewable energy technologies, defence applications, and high-tech industries, has seen rising demand globally. The Emma and Mammoth mines, averaging around 1.5% antimony with zones exceeding 2%, exemplify the high-grade nature of mineralisation at the site. Trigg’s discovery of repetitive massive stibnite zones aligns with its exploration model, which leverages decades of combined antimony expertise.

Next Steps – Geophysical Surveys and Target Refinement

Building on these promising field observations, Trigg is preparing to deploy advanced geophysical techniques, including HeliSAM and galvanic source electromagnetics, to refine its geological model and identify priority drill targets. These surveys are expected to enhance understanding of the structural controls on mineralisation and potentially reveal extensions beyond historically defined limits. The company’s approach reflects a modern exploration strategy aimed at unlocking the full potential of the underexplored project area.

Broader Development and Funding Prospects

Trigg has also identified several sites within the project area suitable for smelter development, strategically located near higher-grade mines. This infrastructure potential could be pivotal in establishing a domestic antimony supply chain, particularly as federal funding interest grows for critical mineral projects. The company is actively engaging with funding bodies and exploring strategic partnerships to support the project’s advancement toward resource delineation and eventual production.

Outlook and Market Positioning

Managing Director Andre Booyzen emphasised the significance of the confirmation of massive stibnite zones, noting it as a key step toward establishing Antimony Canyon as a major domestic source of antimony. While laboratory assays are still pending, the early field results provide a strong foundation for confidence in the project’s prospects. As global demand for critical minerals intensifies, Trigg’s progress at Antimony Canyon positions it well to contribute meaningfully to supply chains essential for national security and the energy transition.

Bottom Line?

Trigg Minerals’ Antimony Canyon Project is poised for a pivotal exploration phase that could reshape domestic antimony supply.
