Utah’s Antimony Resource: A Strategic Investment Play in Critical Minerals
Utah may be best known for its copper and gold legacy, but hidden beneath its rugged terrain lies one of the most overlooked critical mineral opportunities in the US: antimony.
With global supply heavily concentrated in China and export restrictions tightening, Utah’s underexplored antimony deposits are gaining new relevance. For investors, this presents a timely and potentially undervalued opportunity to get ahead of a domestic supply chain revival, with early movers leading the way.
Once home to scattered historic antimony production, Utah is now re-emerging as a strategic hotspot for this essential element.
Growing demand for antimony
Antimony is increasingly recognized as a mineral of strategic importance due to its broad industrial and defense applications. Used in flame retardants, semiconductors, lead-acid batteries, military-grade alloys and solar energy systems, it plays a vital role in modern manufacturing and national security.
The US government lists antimony as a critical mineral, emphasizing the risk posed by concentrated foreign supply. Notably, China currently controls 83 percent of global production and 55 percent of reserves.
The geopolitical implications are significant. China has imposed export bans on antimony in recent years, raising alarm over Western access and increasing pressure on governments and industries to secure domestic sources. Growing demand, driven in part by renewable energy and military applications, underscores the urgency of diversifying supply.
Utah: A re-emerging antimony source
Utah is globally known and well-established as a mining-friendly jurisdiction, with a history that dates back to the 19th-century silver and copper booms. Today, it remains a top-tier destination for mineral investment providing an ideal blend of regulatory clarity, skilled workforce and robust infrastructure — including highways, rail and energy networks.
The Utah Geological Survey has identified critical minerals as a top exploration priority, encouraging public-private collaboration and supporting legislative initiatives to streamline permitting processes and promote investment.
This pro-mining posture is timely, as the global push for critical mineral security has spurred renewed interest in Utah’s subsurface wealth — such as antimony, which has been documented in the state since the early 1900s.
Geologically, Utah sits at the convergence of highly prospective belts that stretch across eastern Nevada and western Utah. These belts are known for polymetallic mineral systems, including antimony associated with gold, silver and tungsten. Historic antimony production and showings have been identified in several regions, including Antimony Peak, Coyote Knoll, Beaver County, Thomas Range and Wah Wah Mountains.
