American Tungsten & Antimony Discovers High-Grade Antimony in Utah

American Tungsten & Antimony


High-Grade Antimony Identified at Little Emma Prospect

American Tungsten & Antimony recently reported high-grade antimony from initial drilling at the Little Emma Prospect. This drilling marks the start of its inaugural programme and confirms promising stibnite mineralisation. The results indicate potential for a district-scale antimony system within the Antimony Canyon Project in Utah, US.

Initial drill intercepts returned 11.03m at 3.1% antimony from 25.91m, and 2.62m at 12.54% antimony from 29.2m. In addition, 8.47m at 2.67% antimony from 31.15m, including 2.2m at 9.69% antimony from 36.88m, were reported. Another intercept yielded 2.14m at 3.02% antimony from 40.23m. These results validate the company’s geological model and indicate continuity of high-grade mineralisation.


Strategic Importance for US Antimony Supply

Meanwhile, the US Government classifies antimony as a critical mineral due to its use in defence systems, semiconductors, batteries, flame retardants, and advanced manufacturing. Currently, the US relies heavily on imports from China. American Tungsten & Antimony aims to restore domestic supply and secure antimony and tungsten for strategic industries. The company also advances Tennessee Mountain, Sage Hen, Nightingale, and Dutch Mountain tungsten projects across Utah and Nevada.

Andre Booyzen, Managing Director, stated, “Intersecting mineralisation in four of our first seven holes is an exceptional start. Grades reaching 66.47% Sb highlight system strength. These results rival major North American deposits such as Idaho’s Stibnite Gold Project.” The discoveries may enhance US supply security and support industrial and defence applications.


ScrapInsight Commentary

The Little Emma Prospect discovery strengthens US antimony supply and reduces import reliance. Prices may gain support amid supply diversification. This project reinforces the circular economy by enabling domestic critical mineral sourcing.
