Company Overview

United States Antimony Corporation is a U.S.-based materials and mining company engaged in the production and sale of antimony, zeolite, and precious metal products. The company operates within the critical minerals, industrial materials, and specialty metals industries, supplying products used in flame retardants, batteries, military applications, semiconductors, ceramics, and environmental filtration. Its core revenue drivers are antimony metal and antimony oxide sales, along with zeolite mineral products and, to a lesser extent, precious metals recovered through processing activities.

Founded in 1969, United States Antimony Corporation has evolved from a domestic antimony producer into a vertically integrated processor with mining, smelting, and recycling operations. The company is publicly traded on the NYSE American and is one of the few U.S.-linked companies with operational exposure to antimony, a mineral designated as critical by the U.S. government due to supply concentration outside North America. Its strategic positioning centers on supplying Western markets with non-Chinese antimony sources, though it remains a small-cap company with limited scale compared to global peers.

Business Operations

United States Antimony Corporation operates through three primary business lines: Antimony Operations, Zeolite Operations, and Precious Metals Recovery. The antimony segment includes mining, smelting, and refining activities, with products sold to industrial and government-related customers. The company controls the Madero Smelter in Mexico and has access to antimony ore from both owned and third-party sources. Zeolite operations are conducted through its wholly owned subsidiary Bear River Zeolite Company, which produces natural zeolite used in agriculture, animal feed, water filtration, and soil remediation.

Operations span both domestic and international activities, with mining assets and processing facilities located in the United States and Mexico. The company does not currently report material joint ventures but relies on third-party ore suppliers and customer contracts to support production volumes. Revenue generation is primarily transactional, based on commodity sales, and is sensitive to antimony pricing, input availability, and regulatory conditions affecting mining and cross-border trade.

Strategic Position & Investments

The company’s strategic direction focuses on expanding antimony production capacity, securing reliable ore supply, and aligning its operations with U.S. and allied critical mineral supply chain initiatives. United States Antimony Corporation has emphasized reinvestment in existing assets rather than large-scale acquisitions, with capital allocated toward facility maintenance, incremental capacity improvements, and regulatory compliance. Management has also highlighted the strategic importance of antimony in defense and energy storage applications as a long-term demand driver.

Notable subsidiaries include Bear River Zeolite Company, which provides diversification outside of antimony and exposure to agricultural and environmental markets. The company has periodically evaluated additional mineral properties and processing opportunities, though public disclosures indicate that many proposed projects remain exploratory or contingent on financing and market conditions. Data inconclusive based on available public sources regarding any material pending acquisitions or large-scale strategic investments.

Geographic Footprint

United States Antimony Corporation maintains a modest but strategically significant geographic footprint across North America, with its corporate headquarters in Montana, United States. U.S. operations include zeolite mining in Idaho and administrative functions in Montana. Internationally, the company’s most significant operational asset is its antimony smelting facility in Mexico, which serves as a central processing hub for antimony concentrates.

The company’s market presence is primarily focused on the United States, with additional sales into Mexico and select international markets depending on demand and logistics. While its global reach is limited compared to multinational mining firms, its cross-border operational structure provides access to both U.S. and Mexican mineral resources and industrial customers.

Leadership & Governance

United States Antimony Corporation is led by a management team with experience in mining operations, mineral processing, and small-cap public company governance. The leadership philosophy emphasizes operational continuity, disciplined capital allocation, and leveraging the company’s niche position in critical minerals rather than pursuing aggressive expansion. Governance is overseen by a board of directors responsible for strategic oversight, regulatory compliance, and shareholder interests.

Key executives include:

• Gary C. Evans – Chairman of the Board and Chief Executive Officer
• John Lawrence – President and Chief Operating Officer
• Kevin R. Lahr – Chief Financial Officer
• Armando Villasenor – Vice President of Mexican Operations

The executive team has collectively guided the company through commodity price cycles and regulatory changes, with a stated focus on maintaining operational viability and positioning the company within evolving U.S. critical mineral policy frameworks.
