Trigg Defines 6.9 Million Tonnes Exploration Target at Antimony Canyon Project

Geological Breakthrough at Antimony Canyon

Trigg Minerals Limited has announced a significant geological breakthrough at its flagship Antimony Canyon Project in Utah. Independent expert consultancies have reinterpreted the project as a district-scale, high-sulfidation epithermal system, vastly expanding its potential beyond previous assessments. This new model suggests a vertically extensive mineralised system with multiple high-grade zones, supported by outstanding channel samples including assays up to 33.2% antimony.

The company has defined an exploration target on its recently acquired 20 patented claims, ranging from 6.1 to 6.9 million tonnes at grades between 1.4% and 2.3% antimony. This target contains an estimated 86,000 to 158,000 tonnes of antimony metal, although Trigg cautions that further exploration is required to confirm a formal mineral resource.

Strategic Acquisitions Bolster Critical Minerals Portfolio

In addition to the Utah project, Trigg has expanded its critical minerals footprint in the United States with two key acquisitions. The Tennessee Mountain Tungsten Project in Nevada, featuring historic high-grade tungsten mineralisation within a skarn system, offers a promising opportunity to develop a domestic tungsten supply. Historical drilling and trenching data confirm the presence of significant mineralisation, providing a strong foundation for modern exploration.

Further strengthening its position, Trigg is acquiring 100% of the Central Idaho Antimony Project, a district-scale landholding in a Tier-1 mining jurisdiction. This project benefits from excellent infrastructure and a clean environmental baseline, with historical records indicating high-grade antimony and gold mineralisation. The acquisition aligns with Trigg’s strategy to supply conflict-free critical minerals to Western markets.

Corporate Developments and Financial Strength

Trigg’s corporate position remains robust, with a cash balance of approximately A$16.7 million as of 30 September 2025. This strong funding base supports the company’s accelerated exploration and development plans, including permitting and drilling preparations at Antimony Canyon. The appointment of Chris Gregory, an experienced mining executive with a track record in antimony projects, to the board further enhances Trigg’s leadership capabilities.

The company is actively pursuing a dual listing on the US NASDAQ exchange to broaden its investor base and is evaluating multiple pathways to achieve this. A proposed name change to American Tungsten and Antimony Ltd reflects the company’s evolving focus on these critical minerals.

Advancing Towards Production and Processing

Trigg is progressing a conceptual study for an antimony smelter using Metso’s Ausmelt technology, aiming to establish one of the few mine-to-metal antimony supply chains in the Western world. The proposed facility would produce high-purity antimony ingots and antimony trisulfide, incorporating advanced environmental controls and efficient processing technology.

Permitting efforts are underway with the submission of a Notice of Intent for exploration drilling at Antimony Canyon, supported by completed geophysical surveys to guide target selection. These steps position Trigg to move swiftly into the next phase of exploration and potential development.
