American Tungsten & Antimony Reports Significant Antimony Findings in Utah

American Tungsten & Antimony Ltd. (ASX: AT4; OTCQB: ATALF) has made headlines with its promising discovery of high-grade antimony at the Little Emma Prospect. This exciting revelation comes from the company's first drilling operations at the Antimony Canyon Project located in Utah, marking a robust initiation for their inaugural drilling program that anticipates a substantial antimony system in the United States.

The initial drilling efforts revealed striking stibnite mineralization in shallow depths, validating the company's geological model and indicating a consistent mineralized system. Notable intercepts recorded included:

• - 11.03m @ 3.1% Sb from 25.91m, including 2.62m @ 12.54% Sb from 29.2m
• - 8.47m @ 2.67% Sb from 31.15m, including 2.2m @ 9.69% Sb from 36.88m
• - 2.14m @ 3.02% Sb from 40.23m

The Little Emma Prospect is just one of several historical antimony mines situated within AT4's patented claim block in Antimony Canyon, showcasing the considerable exploration potential the area holds.

A Strong Start to Exploration

The impressive results follow a prior announcement on March 10, 2026, detailing encouraging outcomes from the initial drilling campaign. Managing Director Andre Booyzen expressed optimism about the findings, stating that intersecting mineralization in four of the first seven holes is a remarkable opening at Antimony Canyon. The notable grades, reaching up to 66.47% Sb, suggest a solid mineral system. Comparisons drawn with other major North American antimony deposits, such as Idaho's Stibnite Gold Project being developed by Perpetua Resources, bolster confidence in the potential of this site.

Booyzen elaborated on the signs of a significant hydrothermal system capable of hosting a noteworthy antimony resource. Many of the largest antimony deposits globally are found in China, developed under similar geological systems, and the characteristics emerging at Antimony Canyon appear to align with those vast deposits.

The discovery includes extensive sulphidation and numerous large anomalous zones, fostering beliefs that Antimony Canyon could evolve into a pivotal new antimony district in the U.S., potentially becoming one of the largest domestic antimony deposits unveiled to date.

Strategic Importance of Antimony

Classified as a critical mineral by the U.S. Government, antimony plays a crucial role in national security due to its applications in defense systems, semiconductors, batteries, flame retardants, and advanced manufacturing. The U.S. currently faces challenges with a heavy reliance on foreign suppliers for antimony, a situation historically dominated by Chinese production. Therefore, the emergence of a significant domestic resource presents a decisive step toward enhancing U.S. supply chain security.

Expanding the Portfolio of Critical Minerals

American Tungsten & Antimony aims to reinstate domestic supplies of antimony and tungsten, both critical minerals essential for defense and industrial supply chains. The Antimony Canyon Project in Utah is a defining part of this strategy, accompanied by a growing portfolio of valuable U.S. projects:

• - Tennessee Mountain Tungsten Project – Nevada
• - Sage Hen Tungsten Project – Nevada
• - Nightingale Tungsten Project – Nevada
• - Dutch Mountain Tungsten Project – Utah

These initiatives position AT4 as an emerging leader in the development of strategically vital critical minerals within the United States, catering to the escalating demand for reliable domestic supply lines. As exploration continues and more results arise, the implications of these discoveries could reshape the landscape of antimony resources in the U.S. and strengthen national security frameworks.
